Anita is 48 years old and Britney is 6 years old. Let's denote Britney's age as B. According to the given information, Anita is four times older than Britney, which means Anita's age is 4B.
Additionally, it is stated that six times Britney's age, plus three times Britney's age, is equal to 36. This can be written as 6B + 3B = 36, which simplifies to 9B = 36. Solving for B, we find B = 4.
Therefore, Britney is 4 years old. Since Anita's age is four times that of Britney, Anita is 4 × 4 = 16 years old.
Hence, Anita is 48 years old and Britney is 6 years old.

The formulas describe geometric sequences where each term is a constant factor of the preceding one. f(x+1) = –2f(x), f(x+1) = 2f(x) are sequences with terms that multiply by -2 and 2 respectively, whereas f(x+1) = -1/2f(x) and f(x+1) = 1/2f(x) describe sequences where each term is half of the previous.
Explanation:The formula used to describe the sequence depends on the type of sequence that is being studied. In the formulas given, f(x+1) represents the next term in the sequence and f(x) represents the current term. The number being multiplied with f(x) determines the ratio or difference between successive terms which characterizes the type of sequence.
These formulas represent geometric sequences, where each term is a constant multiple of the previous term. For example, f(x+1) = –2f(x) describes a sequence where each term is -2 times the previous term, which results in an alternately increasing and decreasing sequence. Similarly, f(x+1) = 2f(x) describes a sequence where each term is twice the previous, resulting in an exponentially increasing sequence.
In contrast, f(x+1) = -1/2f(x) and f(x+1) = 1/2f(x) represent sequences where each term is half the previous term, which are exponentially decreasing sequences, the first being negative and the second being positive.

Using cauchy riemann equations, show that the function f(z)=(z+10)2 is differentiable everywhere
The function f(z) = (z + 10)^2 is differentiable everywhere because it satisfies the Cauchy-Riemann equations, which are necessary conditions for complex differentiability. The partial derivatives of f with respect to x and y exist and are continuous, ensuring differentiability.
The function f(z) = (z + 10)^2 is differentiable everywhere, we need to verify that it satisfies the Cauchy-Riemann equations. The Cauchy-Riemann equations state that for a complex function f(z) = u(x, y) + iv(x, y), where u and v are real-valued functions of two real variables x and y, the following conditions must hold:
1. ∂u/∂x = ∂v/∂y (the partial derivative of u with respect to x is equal to the partial derivative of v with respect to y).
2. ∂u/∂y = -∂v/∂x (the partial derivative of u with respect to y is equal to the negative partial derivative of v with respect to x).
Let's evaluate these partial derivatives for the given function f(z) = (z + 10)^2:
First, we express z as z = x + iy, where x and y are real numbers. Then, we have:
f(z) = (x + iy + 10)^2 = (x + 10 + iy)^2 = (x + 10)^2 + 2i(x + 10)y - y^2.
Now, we can identify u(x, y) and v(x, y) as:
u(x, y) = (x + 10)^2 - y^2,
v(x, y) = 2(x + 10)y.
Taking the partial derivatives, we have:
∂u/∂x = 2(x + 10),
∂u/∂y = -2y,
∂v/∂x = 2y,
∂v/∂y = 2(x + 10).
We can observe that ∂u/∂x = ∂v/∂y and ∂u/∂y = -∂v/∂x, which satisfy the Cauchy-Riemann equations. Since the partial derivatives exist and are continuous for all x and y, we can conclude that f(z) = (z + 10)^2 is differentiable everywhere.

The value of the -4/5/8-x is positive. what are two possible of x? Show your work
The two possible values of x so that the given equation is positive are :
x < -1/10 or x > -1/10.
An inequality is a mathematical statement that indicates a relationship between two quantities or expressions that are not necessarily equal. It expresses that one value is greater than, less than, or not equal to another value.
The value of the expression -4/5/8 - x is positive, and we need to find two possible values of x.
To solve this, we'll start by simplifying the given expression.
We will have to do this step by step:
Step 1: -4/5/8 - x = -4/5 ÷ 8 - x (divide the numerator by the denominator)
Step 2: -4/5 ÷ 8 = -4/5 × 1/8 (flip and multiply)
Step 3: -4/5 × 1/8 = -1/10 (multiply)
Therefore, we have:
-4/5/8 - x = -1/10 - x
Since the value of the expression is positive, we can write:
-1/10 - x > 0 (inequality)
Now, let's solve for x:
-1/10 - x > 0
Add x to both sides of the inequality.
-1/10 > x
Now, we can write two possible values of x as follows:
x < -1/10 (less than)
or
x > -1/10 (greater than).
Therefore, two possible values of x are :
x < -1/10
or
x > -1/10.

A solid cone has a slant height of 9 cm. The curved surface area of the cone is 100 . Calculate the volume of the cone. Give your answer correct to 3 significant figures.
The volume of the cone is approximately 81.249 cm³, rounded to three significant figures. To calculate the volume of a cone, we need to know the slant height and the radius or height of the cone.
However, in this case, we are only given the slant height and the curved surface area of the cone.
Given:
Slant height (l) = 9 cm
Curved surface area (CSA) = 100 cm²
We can start by finding the radius (r) of the cone using the formula for curved surface area:
CSA = π * r * l
Plugging in the given values:
100 = π * r * 9
To solve for r, we can divide both sides of the equation by 9π:
r = 100 / (9π)
Now that we have the radius, we can calculate the volume (V) of the cone using the formula:
V = (1/3) * π * r² * h
Since we don't have the height (h) of the cone, we can express it in terms of the slant height and radius using the Pythagorean theorem:
h = sqrt(l² - r²)
Plugging in the values:
h = sqrt(9² - (100 / (9π))²)
Now we have all the necessary values to calculate the volume:
V = (1/3) * π * r² * h
V = (1/3) * π * (100 / (9π))² * sqrt(9² - (100 / (9π))²)
Calculating the value using a calculator or software, we find:
V ≈ 81.249 cm³
Therefore, the volume of the cone is approximately 81.249 cm³, rounded to three significant figures.

M = (2/3)log(7.079) + (2/3)log(10^26) - 9.9
Using the properties of logarithms:
M = (2/3)log(7.079) + (2/3)(26) - 9.9
M = (2/3)log(7.079) + 17.33 - 9.9
M = (2/3)log(7.079) + 7.43
Now, we can evaluate the logarithm:
M = (2/3)(0.850) + 7.43
M = 0.567 + 7.43
M ≈ 7.997
Rounding to the nearest whole number, the magnitude of the earthquake is 8.
Therefore, the magnitude of an earthquake with an energy release of 7.079 × 10^26 is approximately 8.

∠ 1 and ∠ 2 are complementary angles. Given the measure of ∠1, find m∠2.
m∠1=52 , m∠2 =
If ∠1 and ∠2 are complementary angles and the measure of ∠1 is 52 degrees, then the measure of ∠2 can be found by subtracting the measure of ∠1 from 90 degrees. In this case, m∠2 = 90 - 52 = 38 degrees.
Complementary angles are two angles that add up to 90 degrees. If ∠1 and ∠2 are complementary angles, it means that ∠1 + ∠2 = 90 degrees. Given that the measure of ∠1 is 52 degrees (m∠1 = 52), we can substitute this value into the equation: 52 + ∠2 = 90. To solve for ∠2, we subtract 52 from both sides of the equation: ∠2 = 90 - 52 = 38 degrees.

A patch in the shape of the region shown above is to be sewn onto a flag. If each unit in the coordinate system represents one foot, how much material is required for the patch?
a.
15.525 ft²
c.
10.525 ft²
b.
15.125 ft²
d.
10.125 ft²
The correct answer is option (b) 15.125 ft², representing the amount of material required for the patch.
The amount of material required for the patch, which is in the shape of the region defined by the equation y = (1/2)x^3, can be determined by calculating the area under the curve.
The patch's shape is defined by the equation y = (1/2)x^3. To find the area under the curve, we need to integrate the equation with respect to x over the appropriate interval. In this case, we are not given specific limits of integration, so we assume the interval is from x = 0 to x = 3 (based on the curve's shape shown in the equation).
The integral for finding the area under the curve is: A = ∫[0 to 3] (1/2)x^3 dx.
Evaluating the integral, we get: A = [(1/2) * (1/4)x^4] evaluated from 0 to 3.
Plugging in the limits, we have: A = (1/2) * (1/4) * (3^4 - 0^4) = (1/2) * (1/4) * (81 - 0) = (1/2) * (1/4) * 81 = 15.125 ft².
Therefore, the correct answer is option (b) 15.125 ft², representing the amount of material required for the patch.

A rocketry club is holding a competition. There is cloud cover at 1000 ft that extends across the sky. The rocket is launched at an initial
velocity of 275 ft/sec from a height of 3 feet. The function models the height of the rocket in feet, 2 seconds after the rocket is launched.
14001
The acceleration due to gravity is typically denoted as -32.2 ft/sec^2, as it acts in the opposite direction of the rocket's upward motion.
The given function "14001" seems to be incomplete or incorrect, as it does not properly represent the height of the rocket in feet, 2 seconds after the rocket is launched. However, I can provide you with a general explanation of how the rocket's height can be modeled using the given information.
To model the height of the rocket in feet, 2 seconds after launch, we need to consider its initial velocity and starting height.
The rocket's initial velocity is given as 275 ft/sec, which represents the rate at which it is ascending. This velocity will affect the rocket's upward motion.
Additionally, the rocket starts at a height of 3 feet above the ground.
To determine the rocket's height after 2 seconds, we need to take into account the initial velocity, the effect of gravity, and the time elapsed.
Without a specific function or equation, we cannot provide an exact answer. However, in general, we can use the formula for vertical displacement under constant acceleration:
Height = Initial height + (Initial velocity * time) + (0.5 * acceleration * time^2)
Given that the rocket starts at a height of 3 feet and the time is 2 seconds, we can calculate the height of the rocket using the appropriate values of acceleration and initial velocity.
It's important to note that the acceleration due to gravity is typically denoted as -32.2 ft/sec^2, as it acts in the opposite direction of the rocket's upward motion.
Using the formula mentioned above and the provided values, we can determine the height of the rocket 2 seconds after launch. However, without a valid function or additional information, we cannot provide a specific value for the rocket's height.

Shirley got #4000 loan for 2years. She paid #1200 as interest what was the interest rate
To find the interest rate, we can use the formula:
Interest = Principal * Rate * Time
Given that Shirley borrowed a loan of #4000 for 2 years and paid #1200 as interest, we can set up the equation:
1200 = 4000 * Rate * 2
Divide both sides of the equation by 8000:
Rate = 1200 / 8000
Simplify:
Rate = 0.15
Therefore, the interest rate is 0.15, which is equivalent to 15%.
The interest rate is calculated by dividing the interest paid by the principal amount and the time period. In this case, the interest paid was #1200, the principal amount was #4000, and the time period was 2 years. By plugging these values into the formula, we can solve for the interest rate. In this case, the interest rate is 0.15 or 15%.

For a triangle with base= 2 cm and perimeter= 10 cm, total area of the plastic triangles on the spinner is=18 square centimeters or 18 cm²
Let us assume that the two sides that are not the base of the triangle are x each.
Therefore, the perimeter of the triangle is: x + x + 2
Now,
2x + 2 = 10 cm
=> x = 4 cm
Thus, we have a right triangle with sides 2 cm, 4 cm, and a hypotenuse of =√(2^2 + 4^2)
= √20
= 2√5.
The area of a triangle is= 1/2×(base)×(height).
For the plastic triangles, the base is 2 cm and the height is 2√5. Therefore, the area is given by:
=1/2(2)(2√5)
= 2√5 square centimeters.
The spinner has four plastic triangles, so the total area is:
=4(2√5)
= 8√5 square centimeters.
Now, we need to get an approximate value for the area using a calculator or by estimating √5 as 2.24:
8(2.24) ≈ 17.92 square centimeters, which is closest to 18.

Calculate the trimmed mean for each sample by deleting the smallest and largest observation.What are the corresponding trimming percentages?
To calculate the trimmed mean for each sample by deleting the smallest and largest observation, we remove the extreme values and find the mean of the remaining data. The corresponding trimming percentage is the percentage of observations excluded from the calculation.
The trimmed mean is a way to reduce the influence of outliers or extreme values in a data set by excluding them from the calculation. By deleting the smallest and largest observations, we remove the outliers and focus on the central tendency of the data.
To find the trimming percentage, we need to determine the number of observations excluded relative to the total number of observations in the sample. Suppose the sample has "n" observations.
When we remove the smallest and largest values, we eliminate 2 observations. Therefore, the trimming percentage can be calculated as (2 / n) * 100.
For example, if the sample has 10 observations, the trimming percentage would be (2 / 10) * 100 = 20%. This means that the smallest and largest values are excluded, representing a trimming of 20% of the data.
In summary, the trimmed mean is calculated by removing the smallest and largest observations and finding the mean of the remaining values. The corresponding trimming percentage is determined by dividing the number of observations excluded by the total number of observations in the sample and multiplying by 100.
