What is the domain of the function represented by the graph?

the graph of a quadratic function with a maximum value at the point (2,4) and zeros at 0 and 4

A.
x ≥ 0
B.
0 ≤ x ≤ 4
C.
all real numbers
D.
x ≤ 4

Answer:

To find the solution, plug in 8 for d

d=-3x2+16  

8=-3x2+16  Subtract 8 from both sides

0=-3x2+8

Now, use the quadratic equation to solve for x  

a=-3

b=0

c=8

x=1.63 or  

C. 1.6s

Step-by-step explanation:

The skateboarder is 8 feet from the bottom of the hill after 1.633 seconds.

Quadratic functions are polynomial functions consisting of variables and exponents and the degree of the variable is 2.

The general form of a quadratic function is f(x) = ax² + b x + c.

Given that,

Quadratic function which models a skateboarder’s distance, in feet, from the bottom of a hill x seconds after the skateboarder starts moving down the hill is,

d = –3x² + 16

We have to calculate after how many seconds is the skateboarder 8 ft from the bottom of the hill.

d = 8 feet. Substitute it.

–3x² + 16 = 8

–3x² = 8 - 16

3x² = 8

x² = 8/3

x = √(8/3) seconds

  ≈ 1.633 seconds

Hence the time is approximately 1.633 seconds.

Answer:

The width is 12.5

Step-by-step explanation:

so you would do 150 divided by 12 which would give you 12.5 so the width has to be 12.5 because length times width = area and 12.5 time 12 = 150

Hope this helped :3  o(*￣▽￣*)ブ

Answer:

12.5 ft

Step-by-step explanation:

Area of a rectangle of length L and width W:  A = L * W

Then 150 ft^2 = (12 ft)(width), and so:

(width) = (150 ft^2) / (12 ft) = 12.5 ft

Answer:

The answer is A.

Step-by-step explanation:

You have to use the formula of volume of cone,

[tex]v = \frac{1}{3} \times \pi \times {r}^{2} \times h[/tex]

Given that the diameter of cone is 10 units so the radius is 5. Then substitute the followung values into the formula :

Let r = 5 units,

Let h = 45 units,

[tex]v = \frac{1}{3} \times \pi \times {5}^{2} \times 45[/tex]

[tex]v = \frac{1}{3} \times \pi \times 1125[/tex]

[tex]v = 375\pi \: \: {units}^{3} [/tex]

Answer:

[tex]375\pi \: \: units ^{3} [/tex]

Step-by-step explanation:

[tex]v = \pi {r}^{2} \frac{h}{3} \\ =\pi \times 5 \times 5 \times \frac{45}{3} \\ = \pi \times 25 \times 15 \\ = 375\pi \: \: units ^{3} [/tex]

w=9z

Step-by-step explanation:

For each z value, w is 9 times that. For instance, 18 is 9 times 2, and 45 is 9 times 5. Therefore, the equation that would describe this is w=9z. Hope this helps!

Answer:

z = (1/9) w or w = 9z

Step-by-step explanation:

w = 18 , z = 2

if relationship is proportional than z = k (constant) *w

2 = k * 18 divide each side by 18

k = 2/18 = 1/9

0.5 inch on the drawing

Step-by-step explanation:

The following information is missing:

The scale factor of the drawing to the actual flag is represented by the ratio 1:18.

This scale factor means that 1 inch on the drawing are equivalent to 18 inches o n the actual flag. We want to know the height on the drawing, given that a height of 9 inches is drawn on the actual flag. The following proportion must be satisfied:

1 inch on the drawing / x inch on the drawing = 18 inches o n the actual flag / 9 inches o n the actual flag

x = 9/18 = 0.5 inch on the drawing

7^12  or 7 to the 12th power!

Step-by-step explanation:

[tex]7^{14}[/tex] ÷ [tex]7^{2}[/tex] = [tex]7^{12}[/tex]

14-2=12

7 stays as the base so

[tex]7^{12}[/tex]

The solution is, 7^12  or 7 to the 12th power, is the expression which is equivalent to: 7^14 divided by 7^2.

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

7^14 divided by 7^2

now, we have to find the expression which is equivalent to: 7^14 divided by 7^2.

so, we have,

7^14 ÷ 7^2

= 7^14 / 7^2

=7^14-2

as, we know that,

14-2=12

so, we get,

7^14-2

=7^12

as, we know,

7 stays as the base so,

7^14 ÷ 7^2 = 7^12

Hence, The solution is, 7^12  or 7 to the 12th power, is the expression which is equivalent to: 7^14 divided by 7^2.

Answer:

45

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 3 - 2 = 1, thus

[tex]a_{44}[/tex] = 2 + (43 × 1) = 2 + 43 = 45

Answer:

1)  y = -3x + 9

2) y = -3/4x + 6

3) y = x - 5

Step-by-step explanation:

1) 3x + y - 7 = 2

            +7   +7

        3x + y = 9

       -3x        -3x

                y = -3x + 9

2) 3x + 4y = 24

  -3x           -3x

          4y = -3x + 24

          4        4      4

          y = -3/4x + 6

3) x - y = 5

  -x        -x

      -y = -x + 5

       -1     -1   -1

        y = x - 5

Answer:

This is an example of independent probability.

Step-by-step explanation:

Independent events are not affected by previous events, just like the outcome of rolling a dice is not effected by the previous outcome. (The dice has no memory of any kind, what so ever!).

When two events are said to be independent of each other, meaning the probability that one event occurs in no way affects the probability of the other event occurring. Another example of an independent event is when you flip a coin. (The coin has no memory of any kind, what so ever!).

Multiplication Rule: When two events, A and B, are independent, the probability of both occurring is:

P(A and B) = P(A) · P(B)

The dice was cast 10 times. In three occasions a 5 came out, and in 7 occasions another outcome occurred. The probability of the outcome of exactly 3 times a 5 in 10 casts, can be calculated as:

P(5) =(1 / 6)^3 + (5 / 6)^7

P(5) = 0.28

P(5) = .3

Answer:

k = -1

Step-by-step explanation: 6-4 = k-3k

subtract: 2 = -2k

divide both sides by -2: k = -1

simplifying is easy! we simply add or subtract like terms on each side.

6-4=2

1-3=-2 and then add k which is the variable so -2k

The equation would be 2=-2k and then we can divide both sides by -2 to isolate the variable to get -1=k
