Find the output, y, when the input, x, is -5.

Answer:

BCDE= 100+ 80+100+80 = 360 degree

BAC = 20 degree

DBC = 100 degree

BDE = 80 degree

Shows all is correct

We associate isosceles trapezoid in this question, this helps us prove with angle A in the triangle vertices how we can find one of the adjacent angles from the trapezoid by subtraction when all angles within one single trapezoid = 360 degrees. We can use 20 degree angle A to subtract and find each alternative angle easier.

Step-by-step explanation:

The semi circle shows 9 stones

Where angles are interior to the trapezoid

Where all 4 sided shapes add up to 360 degree

We draw a line of symmetry on BCED angle

To make midway points BC  and DE = 90 degree

The two new formed shapes are still 4 sided and add up to 360 degree.

BC + DE = 180 degree

BDE = Triangle 180 -20/2 = 160/2 = 80

BCDE = Trapezoid = 360

Trapezoid angle DBC = 360-80-80/2 = 360-160/2 = 200/2 = 100 degree  

Finding interior angle A (BAC)

BAC = 180/9 = 20 degree

BAC * (2) = 360 degree circle

BAC = 360/18 = 20 degree

Proves BAC = 20 degree

20 degree is used in BAC workings above in bold and proves all trapezoid angles are correct. We now know this is an isosceles trapezoid and that is why symmetry and midway points can help us find the angles without any given length.

Notice that 81 = 9 * 9

So here is the first expression:

● 9^2

9 is 3^2 so 9^2 is 3^4

That's another expression

● 3^4

81 = 9*9 = 3*3*3*3 = 3^3 *3

That's another expression

● 3*3^3

You can keep manipulating the product and create many expressions like:

● 3^2 * 3^2

● 9 * 3^2

Let's take a look at the dimensions of the cube. Since each cube has a side length of 1, the answer to the question is 1 x the number of cubes. Counting the sides gives 2 x 3 x 4, or 24 yd^3

Answer:

see explanation

Step-by-step explanation:

Given

x² - 6x = - 5

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- 3)x + 9 = - 5 + 9 [ part a, c = 9 ]

(x - 3)² = 4 [ part b ]

Take the square root of both sides

x - 3 = ± [tex]\sqrt{4}[/tex] = ± 2 ( add 3 to both sides )

x = 3 ± 2

Thus part c is

x = 3 - 2 = 1

x = 3 + 2 = 5

interval [3,6]

as you can see only values of x, having a value y in the graph.

Answer:

33

Step-by-step explanation:

We can write an equation:

x+x+1+x+2+x+3=130

x represents the smallest number of the consecutive integers

By the way, an example of consecutive would be 2, 3, 4, 5 or 10, 11, 12, 13

We can combine like terms from our equation:

4x+6=130

4x=124

x=31

The smallest number is 31. The second number would be 31+1=32, which means the third number is 33!

Hope this helps! :) :)

Answer:

[tex]\huge\boxed{3rd\ number = 33}[/tex]

Step-by-step explanation:

Let the consecutive numbers(Coming one after another) be x, x+1, a+2 and x+3

So,

x+x+1+x+2+x+3 = 130

4x + 6 = 130

Subtracting 6 to both sides

4x = 130-6

4x = 124

Dividing both sides by 4

x = 32

So,

1st number = x = 31

2nd Number = x+1 = 31+1 = 32

3rd number = x+2 = 31+2 = 33

4th number = x+3 = 31+3 = 34

Answer:

H, 40%

Step-by-step explanation:

We can start out simple by finding out the number of cars in each category.

30 remote-controlled cars

90 non remote-controlled cars.

20% of the remote controlled cars are yellow, meaning that there are 6 yellow remote controlled cars.

Since 50% of the total cars are yellow, there are 60 yellow cars. Subtracting this from the yellow remote controlled cars, there are 54 yellow non remote contolled cars.

What this means is that 54/90 of the non-remote cars are yellow, and 36/90 of the non-remote cars are yellow. 36/90 is just 2/5, which means that our answer is H, 40%.

Answer:

63 degrees

Step-by-step explanation:

(180-54)/2=126/2=63

Answer:

The value of y is 63

Step-by-step explanation:

The sum of angles in a triangle is 180°.

The angles in the triangle are 54°, y°, y°

Sum of angles in the triangle = 54° + y° + y° = 54 + 2y°

To find y, equate the sum of the angles in the triangle to 180°

54° + 2y° = 180°

2y° = 180° - 54°

2y° = 126°

y = 126/2 = 63

3.35 (3 sig.fig)

Triangle ABC

AC = BC, AB = 3, CD perpendicular to AB, CD =3

AC (Hypotenuse)

AC = BC shows that Triangle ABC is an isosceles triangle.

As CD is perpendicular to AB, and, both sides

(AC & BC) have equal angles and length, making the line CD cut right across the triangle.

(Point D is in the middle of Line AB)

Resulting in 2 EQUAL triangles in Triangle ABC.

To find one of the 2 triangles:

1. Take Line AB and divide it in half as both sides are equal.

Line AD = 3 / 2

= 1.5

2. Use the Pythagoras Theorem to find Line AC (Hypotenuse). [c^2 = a^2 + b^2]

a : Line AD = 1.5

b : Line CD = 3

c^2 = 1.5^2 + 3^2

c^2 = 2.25 + 9

c^2 = 11.25

c = (Square Root) 11.25

c = 3.35 (3 significant figure)

Therefore, the answer is:

Answer:

0.5 L

Step-by-step explanation:

volume of bottle: 1.5 L

amount of water = 1.5 L

volume of glass: x

3/4 full is the same as 0.75 full

vol of water in bottle + vol of water in glass = total vol of water

      0.75(bottle)          +       0.75(glass)          =           1.5

0.75(1.5) + 0.75x = 1.5

0.75x = 0.375

x = 0.5

Answer:

h(x + 1) = (x+3)(x-1)

Step-by-step explanation:

Simply plug the value of x+1 into the equation for x.

h(x) = x^2 - 4

h(x + 1) = (x + 1)^2 - 4

h(x + 1) = x^2 + 2x + 1 - 4

h(x + 1) = x^2 + 2x - 3

h(x + 1) = (x+3)(x-1)

Step-by-step explanation:

The points from the table need to have a constant slope for the function to be linear.

Slope is rise over run.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

For (1,1) and (2,2):

[tex]m=\frac{2-1}{2-1}=\frac{1}{1}=\boxed{1}[/tex]

The slope is 1.

For (3,6) and (4,24):

[tex]m=\frac{24-6}{4-3}=\frac{18}{1}=\boxed{18}[/tex]

The slope is 18.

1 ≠ 18

Since the slopes of the points are no consistent, the table represents a nonlinear function.

Therefore,

The table does NOT represent a linear function.

Answer:

The answer is B

Step-by-step explanation:

A line has Zero slope is when the line is parallel to the x-axis. The slope of the first pair of coordinates will have no slope or zero slopes.

The slope of a line is given by the formula,

[tex]m = \dfrac{(y_2-y_1)}{(x_2-x_1)}[/tex]

where (x₂,y₂) and (x₁,y₁) are the coordinates of any point on the line of slope.

1. For the first slope, the given coordinates are

(-3,2),(-1,2),(1,2),(3,2)

Now, if we take the first and the last point to calculate the slope of the line, we will get,

[tex]m = \dfrac{(y_2-y_1)}{(x_2-x_1)} = \dfrac{2-2}{-3-3}=\dfrac{0}{-6}=0[/tex]

Thus, the slope of the line is 0. And if we plot the points on the graph we will see that the slope of the line is 0.

2. For the second slope, the given coordinates are

(-3,3),(-1,1),(1,-1),(3,-3)

Now, if we take the first and the last point to calculate the slope of the line, we will get,

[tex]m = \dfrac{(y_2-y_1)}{(x_2-x_1)} = \dfrac{3-(-3)}{-3-3}=\dfrac{6}{-6}=-1[/tex]

Thus, the slope of the line is -1. And if we plot the points on the graph we will see that the slope of the line is -1.

3. For the third slope, the given coordinates are

(-5,-5), (0,0), (5,5)

Now, if we take the first and the last point to calculate the slope of the line, we will get,

[tex]m = \dfrac{(y_2-y_1)}{(x_2-x_1)} = \dfrac{-5-5}{-5-5}=\dfrac{-10}{-10}=1[/tex]

Thus, the slope of the line is 1. And if we plot the points on the graph we will see that the slope of the line is 1.

4. For the fourth slope, the given coordinates are

(-2,5), (-2,0), (-2,5)

Now, if we take the first and the last point to calculate the slope of the line, we will get,

[tex]m = \dfrac{(y_2-y_1)}{(x_2-x_1)} = \dfrac{5-0}{-2-(-2)}=\dfrac{5}{0}[/tex]

Thus, the slope of the line is undefined. And if we plot the points on the graph we will see that the slope of the line is undefined or at 90° from the x-axis.

Hence, the slope of the first pair of coordinates will have no slope or zero slopes.

Answer:

Normal; increases.

Step-by-step explanation:

In Statistics and probability, a student t-distribution also known as the t-distribution refers to the continuous probability distribution which can be used to estimate population parameters when the population variance or standard deviation is not known (unknown) and the sample population is relatively small. The student t-distribution is a statistical distribution which was published in 1908 by William Sealy Gosset.

The t-distribution approaches the normal distribution as the sample size increases because the parameters becomes negligibly smaller.

This ultimately implies that, when the degree of freedom of a t-distribution curve is increased in comparison with that of a normal distribution, the value of probability becomes significantly similar.

Answer: The probability would be 1/3.

Step-by-step explanation:

Answer:

1/3

Step-by-step explanation:

Only '1' and '2' are less than '3' on a 6-sided die.

Thus, only 2 out of 6 outcomes are of interest.

The probability of rolling a number less than three on a six-sided die is therefore 1/3.

Answer:

So we have a function such that:

Takes elements of Set A, and maps them into Set B.

So Set A is the domain, and Set B is the range.

Where the domain is defined as the set of all the possible inputs of a function, and the range is the set of the possible outputs.

In principle, yes, if f(x) maps Set A into Set B, all the elements of Set A should be used, why?

Because we need to check if there is a problem with Set A, for example the function f(x) = 1/x has a problem when x = 0, so we remove x = 0 from the domain of that function.

So, a function is only a function if it maps ALL the elements of its domain into only one element in the range.

A "flip" can be considered a reflection.

A "spin" is a rotation.

A "slide" is a translation.

None of these transformations change the way a shape looks, or the size of the shape. They only change how the shape is oriented.
