Evaluate f (x)= [tex]\frac{1}{3}[/tex]x for x = 4



A. [tex]1\frac{1}{3}[/tex]


B. [tex]\frac{3}{4}[/tex]


C. -12


D. [tex]\frac{1}{12}[/tex]

Answers

Answer:

Use the given functions to set up and simplify f.

f =

x  =  1/ 3 x  =   x =  0

x  =  4  =  x  =  0

You would multiply 1/3 by 4 which is 4/3......all it is, is 1/3 multiplied by 4/1

Step-by-step explanation:

A:  Hello!

The answer is: f(4) = 4/3

Why?

Evaluating a function means substituting the variable (x in this case) by the given value (4 in this case), so where is an "x" we should rewrite with the number 4.

So, evaluating the function for  we have:

f(4) = 1/3 (4) = 1/3 *4 = 4/3

Have a nice day!

B:  When evaluating this you get 4/3

C:  Answer:

1) The equation below shows the height of a soccer ball, h(d) meter as a function of the
horizontal distance, d meters the ball travels until it hits the ground. The ball is kicked when
it is on the ground. h(d) = -0.025(d – 20)2 + 12
Always make a sketch to begin even if you are not asked to!
a) What is the maximum height of the ball?
b). What is the horizontal distance of the ball from the kicker when it reaches its maximum
height?
c) How far does the ball travel horizontally from when it is kicked until it hits the ground?

Answers

For the given equation

a)The maximum height of the ball is 12 meters.

b)The horizontal distance of the ball from the kicker is 20 meters.

c)The ball travels approximately 32.85 meters horizontally.

What does equation mean?

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, the left-hand side (LHS) and the right-hand side (RHS), separated by an equal sign (=). The equation can contain variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. Solving an equation means finding the value(s) of the variable(s) that make the equation true.

According to the given information

a) The equation is in vertex form, where the maximum height is the y-coordinate of the vertex. We can see that the vertex is at (20, 12), so the maximum height of the ball is 12 meters.

b) The horizontal distance of the ball from the kicker when it reaches its maximum height is the x-coordinate of the vertex. In this case, the vertex is at (20, 12), so the horizontal distance of the ball from the kicker when it reaches its maximum height is 20 meters.

c) To find the distance the ball travels horizontally from when it is kicked until it hits the ground, we need to find the value of d when h(d) = 0. This is because the ball hits the ground when its height is 0. Setting h(d) = 0, we get:

0 = -0.025(d – 20)2 + 12

Solving for d, we get:

(d – 20)2 = 480

d – 20 = ±√480

d = 20 ± 4√30

Since the ball is kicked when it is on the ground, we only consider the positive value of d:

d = 20 + 4√30

Therefore, the ball travels approximately 32.85 meters horizontally from when it is kicked until it hits the ground.

Step-by-step explanation:

HEB has dish soap that costs $2.80 for a 12oz bottle. Fiesta has the same dish soap that costs $2.00 for a 8 oz tube.

The unit rate at HEB is $
per ounce. The unit rate at Fiesta is $
per ounce. So
has the better buy for dish soap.

Answers

Answer:

The unit rate at HEB is $0.23 per ounce. The unit rate at Fiesta is $0.25 per ounce. So HEB has the better buy for dish soap.

Step-by-step explanation:

To calculate unit rate, you divide the price by the oz.

So for HEB, you should do $2.80/12 oz. This will equal to $0.23 per ounce. For Fiesta, you should do $2.00/8 oz. This will equal to $0.25 per ounce.

To determine which one is the better buy, the lower priced one is better, meaning HEB is the better buy.

A company is deciding which box to us for their merchandise. The first box measures 8in by 6.25in by 10.5in. The second box measures 9in by 5.5in by 11.75in. Which box required more material to make?

Answers

Answer:

the second box

Step-by-step explanation:

To determine which box would use more material to make, the volume of the boxes have to be determined. the box with the larger volume would require more material to make

Volume of a box = length x breadth x height

Volume of box 1 = 8in x 6.25in x 10.5in = 525 in³

Volume of box 2 =  9in x 5.5in x 11.75in = 581.6 in³

the second box has a larger volume and thus would need more material to make

Answers

Answer:

a = 8

r = 15%

When t = 3, y= 4.9

Step-by-step explanation:

8 represents the original amount because that's what you're increasing, so a=8.

To find your percentage, look into the parenthesis to see the decimal. We see that it's 0.15, but that's not a percentage yet, so you have to multiply it by 100. Or, moving your decimal two times to the right. Therefore, r=15%.

Now to find what the function will equal when t=3, simply plug 3 for t. I've always used a calculator for this so I'm not going to write it out (sorry). Your result should be 4.9 (this is already rounded to the nearest tenth for you).
