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.

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.

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.

Answer: a. e= 24

b. f = 40

Step-by-step explanation:

a. 125% of e = 30

125/100 × e = 30

1.25 × e = 30

1.25e = 30

e = 30/1.25

e = 24

b. 35% of f = 14

35/100 × f = 14

0.35 × f = 14

0.35f = 14

f = 14/0.35

f = 40

Answer: 21

Step-by-step explanation:

since 19 is the breadth and the perimeter is 80m, so 19*2=38 and 80-38= 42 so 42/2=21. The answer is 21

6 feet

20/15= 1.3 8/1.3=6.1 round to the nearest tenth and BOOM 6 feet

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

Answer: 27.2

Step-by-step explanation:

A squared + B squared = C squared 22 is A squared and 16 is B squared and C squared is the hypotenuse and that is what we are figuring out

22squared= 484 and 16 squared=256 484+256=740 and 27.2 squared is 740 I hope this helps

Answer:

20

Step-by-step explanation:

locate 10 on the horizontal (x- axis), go vertically up to meet the line at (10, 20)

The corresponding output is the value on the vertical (y- axis )

That is the output is 20

Answer:

probability of rolling a number greater than 3 is 1/2

Step-by-step explanation:

all numbers on a standard number cube: 1, 2, 3, 4, 5, 6

number greater than 3:  4, 5, 6

three out of six, of one-half, are greater than three

Answer:

282.6

Step-by-step explanation:

v=pi r^2 h =3.14x9x10

since diameter is 0.5 feet then it is equal to 6 inch so diveided by 2 give 3 as radius and square 3 give 9 so 3.14x9x10 = 282.74 which 282.6 is the closees answer

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.
