Answer:

Yes this is a function.

Step-by-step explanation:

This graph is a function because it passes the vertical line test. The vertical line test ensures that no x value has more than one y value. You can take a pencil, hold it vertically, and move it horizontally across your paper to test whether or not the graph contains multiple y values for a single x value. If it passes this test, then the graph is indeed a function.

Answer:

B

Step-by-step explanation:

I put A and got it wrong. The correct answer is B.

The function has a range of f(x) ≤ 3/4 is f(x) = -x² + 3/4.

An function is an expression that shows the relationship between two or more numbers and variables.

The range of a function is the set of all output variables.

From the graph plotted;

The function has a range of f(x) ≤ 3/4 is f(x) = -x² + 3/4.

Answer:

C, 8.5

Step-by-step explanation:

The area of a rectangular prism is Length times Width times Height. If the volume of the tank (which is a rectangular prism) is 1360, then the L x W x H is 1360. The area of the base of the tank is determined by multiplying the Length and the Width together, so that means that L x W = 160.

Our first equation

L x W x H = 1360

Our second equation

L x W = 160

We see that 1360 divided by 160 gets us the height of the prism.

1360 / 160 = 8.5, so the answer is C

Answer:

= 50% decrease

Step-by-step explanation:

There is a percentage decrease of 50% in the number of people from 72 people to 36 people

An equation is an expression used to show the relationship between two or more numbers and variables.

There is a change of 72 people to 36 people, hence:

Percentage change = [(36 - 72) / 72] * 100% = -50%

There is a percentage decrease of 50% in the number of people from 72 people to 36 people

Answer: Answer: C. 3.2 × 10^4

Step-by-step explanation: for this case the multiplication of the values with exponent are summed, as the exponent are the 6 and -3

6 - 3 = 3

this will be the exponent of the common value which is the 10.

after you only need to multiply 8 and 4 by separate the

8 * 4 = 32.

then we only need to place the values one by one

32 × 10^3

3 is the result of the sum of the exponent.

10 is the common value.

32 is the result of the product.

if we add another zero to the multiplication we get 3.2 and exponent finish with one more zero, then we get this result

3.2 × 10^4

because of that the C is the correct answer, keep in mind that the other answers do not apply correctly the rule of the exponent, because the rest of answer give us wrong answer with final result of the exponent.

Answer:

[tex]\displaystyle f(x)=-\frac{1}{24}\left(x-12\right)^2+6[/tex]

Where f(x) models the height, in inches, of the frog's leap after it had leapt x inches.

Step-by-step explanation:

We are given that a frog leaps two feet, with the highest point in the jump being six inches.

Assuming the frog starts at (0,0), we want to find a quadratic function in vertex form for the path of the jump.

First, we will convert the length of the jump to inches. Two feet is equivalent to 24 inches.

Next, since the frog started at (0, 0), in order to jump a length of 24 inches, it must have ended at (0, 24). These two points will also be our two roots: x = 0 and x = 24. We can use the factored form of a quadratic:

[tex]f(x)=a(x-p)(x-q)[/tex]

Where p and q are the roots.

Substitute in the roots:

[tex]f(x)=a(x-0)(x-24)=ax(x-24)[/tex]

Now, since the frog reached a maximum height of six inches, the y-coordinate of the function at its vertex point is 6.

Since a parabola is symmetrical along its axis of symmetry, the axis of symmetry is always halfway between the two roots.

Therefore, the x-coordinate of our vertex is:

[tex]\displaystyle x=\frac{24-0}{2}=12[/tex]

So, when x = 12, f(x) = 6. Substitute:

[tex]6=a(12)(12-24)[/tex]

Solve for a:

[tex]\displaystyle- 144a=6\Rightarrow a=-\frac{1}{24}[/tex]

Therefore, our function is:

[tex]\displaystyle f(x)=-\frac{1}{24}x(x-24)[/tex]

Now, we can place this into vertex form:

[tex]\displaystyle f(x)=a(x-h)^2+k[/tex]

Where a is the leading coefficient and (h, k) is the vertex.

Our leading coefficient is -1/24, and the vertex is (12, 6). Hence, our function is:

[tex]\displaystyle f(x)=-\frac{1}{24}\left(x-12\right)^2+6[/tex]

Where f(x) models the height, in inches, of the frog's leap after it had leapt x inches.

Answer:

1. 454

2. 96

Step-by-step explanation:

1. To find The surface area, find the are of each side. The bases of the triangular prism have the same surface area,

Surface area of triangle: 1/2b*h, half of the base times the height. base = 8, height = 10, 1/2(8) * 10 = 4*10 = 40, the other side has the same area, so double it to get 80.

The surface area of one of the rectangle is 11*14, another is 12*11, and the last is 11*8, multiply all to get 154, 132, and 88, and 154 + 132 + 88 + 80 = 454

2. The two triangles is 1/2b * h, b = 6, h = 2, 1/2(6) * 2 = 3*2 = 6, double it because there is another triangle to get 12

The three rectangles are 3*7 + 3*7 + 6*7 = 21 + 21 + 42 = 84, 84 + 12 = 96
