Answer:

In 2020, the price of the phone would be $1000 - (10% * $1000) = $900.

In 2021, the price of the phone would be $900 - (5% * $900) = $855.60.

So the price of the phone in 2021 would be $855.60.

Step-by-step explanation:

The price of the phone in 2021 was $304.

The price of the phone in 2020 was $1000 - $1000*10% = $900.

The price of the phone in 2021 was $900 - $596 = $304.

The correct interpretation for the statement D'(8) = -0.5 is (c) At 8 a.m. the water level was 0.5 meters below sea level.

From the question, we have the following parameters that can be used in our computation:

The function D gives the depth of the water, in meters, t hours after midnight on a certain day

This means that

D = depth in meters

t = time in hours

From the question, we have

Notation = D(n)

Also, from the question, we have

D'(8) = -0.5

This is the inverse of the function D(t)

So, the values of the parameters are

D(t) = -0.5

t = 8

This means that the number of hours is 8 and the depth is -0.5 meters

Hence, the interpretation of D'(8) = -0.5 is (c) At 8 a.m. the water level was 0.5 meters below sea level.

Five 1/2 inch cubes fit along it’s 2 1/2 length.

An object's longest or largest dimension is a measured distance. Dimensions: 10 ft. see Weights and Measures, Metric System Table

An object's length, which is a measurement of its longest side, is its most stretched dimension. Your dog, for instance, would measure its length from the point of its nose to the end of its tail. The space between its top and bottom feet is greater than that of the creature's head.

In addition to utilizing handspan, foot span, and other methods, one can measure length in many units, such as centimeters, inches, meters, and so on.

Let x be the number of 1/2 cubes to fit 2 1/2 length

(1/2)x= 2 1/2

(1/2)x=5/2

x=5

As x and y are directly proportional the value of y is 9 when the value of x is 15.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, The value of y varies directly with x.

So, y ∝ x, Or y = kx, where k is the constant of proportionality.

When the value of y is 6 the value of x is 10.

Therefore, 6 = 10k.

k = 6/10 ⇒ 3/5.

The distance traveled by a particle with position (x, y) as t varies in the time interval 0 ≤ t ≤ 3π be, 6π units.

Given, a particle with position (x, y) move across a distance as t varies in the given time interval 0 ≤ t ≤ 3π

where, x = sin2t, y = cos2t

On using the length of the curve concept, we get

d = ∫√((dx/dt)² + (dy/dt)²) dt

as, x = sin2t and y = cos2t

dx/dt = 2cos2t

dy/dt = -2sin2t

On substituting the values, we get

d = ∫√(4cos²2t + 4sin²2t) dt

d = ∫2 dt

d = 2∫dt

d = 2×(3π - 0)

d = 6π

So, the distance traveled by the particle be, 6π

The complete square for the binomial expression is x² + 15x + [ 15²/4 ].  

→ The squaring of a binomial will always give a trinomial.

For example,  

(a + b)(a + b) = (a + b)² = a² + 2ab + b²  

(ax - b) (ax - b) =  (ax - b)² = ax²  - 2axb + b²

→ If a trinomial (ax² + bx + c ) is perfect square then

The formula for constant term c = [ b/2√a ]²  

Here we have

x² + 15x + __  is a square of the expression

As we know constant term c = [ b/2√a ]²    

=> Constant term of (x² + 15x + __) =  [ 15/2√1 ]² = [ 15²/4 ]    

Therefore the complete expression is  x² + 15x + [ 15²/4 ]  

Here divide and multiply by 2 with 15x

Answer: To calculate the length of a loan, you need to know the total cost of the loan, the monthly payment amount, and the interest rate. In this case, the total cost of the car is $16,000, the monthly payment amount is $250, and the interest rate is 7.3%.

First, you need to calculate the total interest that will be paid on the loan. This can be done by multiplying the total cost of the loan by the interest rate, and then dividing by 100 to convert the result to a percentage. In this case, the total interest paid would be $16,000 * 7.3 / 100 = $1,168.

Next, you need to subtract the total interest from the total cost of the loan to find the total amount of the loan that will be used to pay for the car. In this case, the total amount of the loan used to pay for the car would be $16,000 - $1,168 = $14,832.

Finally, you can use this total amount and the monthly payment amount to calculate the length of the loan by dividing the total amount by the monthly payment amount. In this case, the length of the loan would be $14,832 / $250 = 59.32 months, or just over four years. The answer is 59.32 months.

according to question:

AE = 9X-5

2AE = AC

2(9x-5)= 14x+34

18x-10= 14x+34

4x = 44

x = 11

Now we need to find AC = 14x+34

                                         = 14*11+34

a. To find the extrema of the function f(x,y) = x^2 - y^2 - 2xy - 2x on the triangular region with vertices (1,0), (0,1), and (-1,0), we can consider the points on the boundary of the region as well as the interior points.

On the boundary, we can use a parametrization to evaluate the function at the vertices of the triangle. Letting x = t, we can evaluate the function at the points (t, 0), (0, 1-t), and (-1, -t). Substituting these points into the function, we get:

f(t,0) = t^2

f(0,1-t) = (1-t)^2 - 2(1-t)t

f(-1,-t) = (-1)^2 - (-t)^2 - 2(-1)(-t)

We can then find the maximum and minimum values of these expressions on the given domain. For f(t,0), the maximum value is 1 and the minimum value is 0. For f(0,1-t), the maximum value is 1 and the minimum value is 0. For f(-1,-t), the maximum value is 1 and the minimum value is -1.

Therefore, the maximum value of the function on the boundary is 1 and the minimum value is -1.

We can also use the second derivative test to check for extrema in the interior of the triangle. The Hessian matrix for the function is:

H = [2 -2 -2]

[-2 2 0]

The second derivatives are all continuous on the domain, and the Hessian is negative definite at the point (0,0). This indicates that (0,0) is a local minimum.

Since the maximum and minimum values on the boundary are 1 and -1, respectively, and the local minimum in the interior is -1, the absolute maximum value of the function on the triangular region is 1 and the absolute minimum value is -1.

b. To find the extrema of the function g(x,y) = x + xy - 2y^2 on the domain y ≥ 0, y ≤ x, x ≤ 1, we can consider the points on the boundary of the region as well as the interior points.

On the boundary, we can use a parametrization to evaluate the function at the vertices of the region. Letting y = tx, we can evaluate the function at the points (1, t), (1/t, 1), and (0, 0). Substituting these points into the function, we get:

g(1,t) = 1 + t - 2t^2

g(1/t,1) = 1/t + 1 - 2
