the graph shows the height of a golf ball in meters when it is hit. the height is modeled by f(x)=-5x^2+50x, where x is time in seconds. How long is the ball in the air

Answer:

The distance between those points is 15.

Step-by-step explanation:

1.   (x2-x1) = (8 - -4) = 12

2.   (y2-y1) = (-3 - 6) = -9

3.   (12)^2 + (-9)^2 = 144 + 81 = 225

4.   √225 = 15

5.   15

Answer:A

Step-by-step explanation: I did the quiz

The terminal point of the 0=pi/4 is (2/√2 and 2/√2) and the value of tan0  is 1.

The terminal point of a circle or circular path is the measure of the angle in degrees or radians over the circle, at the endpoint on the coordinate plane.

The equation for the angle is given as,

[tex]\theta=\dfrac{\pi}{4}\rm radians[/tex]

The terminal point and tan 0 has to be found out.As, the value of pi is 180 degrees. Put this value in the above expression as,

[tex]\dfrac{\pi}{4}=\dfrac{180}{4}=45^o[/tex]

Now, as the rotation of it clockwise from the x-axis in quadrant 1to get the degrees of the angle to the terminal point.

Let this is unit circle with radius 1. Therefore, from the unit circle attached below,

[tex]y=\sin(45)\times1=\dfrac{2}{\sqrt{2}}\\x=\cos(45)\times1=\dfrac{2}{\sqrt{2}}[/tex]

[tex]\tan (45)=1[/tex]

Hence, the terminal point of the 0=pi/4 is (2/√2 and 2/√2) and the value of tan0  is 1.

x = 4.5

Step-by-step explanation:

Given a segment joining the midpoints of 2 sides of a triangle, then

the segment is half the length of the 3rd side, that is

5x = 0.5 × 45 = 22.5 ( divide both sides by 5 )

x = 4.5

The answer is 14 2 /3, if the area of the rectangle face is 7 1/3 then you just multiply by the height.

The answer is C

Step-by-step explanation:

I took the quiz and looked it up just to make sure

Answers of the quiz are as follows

A. 75

B. -50

C. 20

D. -12

We have been given that -

Number of questions= 25

Correct answers= x and score= 3

Incorrect answers= y and score= -2

Not answered= z and score= 0

We can calculate the score as:

A) What is the maximum score you could get on the quiz?

Maximum score one can get on the quiz if he / she correct all i.e. -

25 × 3 = 75.

B)  What is the minimum score you could get on the quiz?

Minimum score one can get on the quiz if he / she correct all i.e. -

25 ×-2 = -50.

C)  A student answers 15 questions.10 are correct. How many points does he score?

Scored points = (10 × 3) + (5 × -2)

= 30 -10

=20 points

D) Another student answers 21 questions. 6 are correct. How many points does she score?

= 6 × 3 + (15 × -2)

= 18-30

= - 12 points

Hence, the answer are a- 75 , b- -50 , c - 20, d- -12.

Answer:

x = 2, x = 4

Step-by-step explanation:

Begin by letting f(x) = 0 , that is

x² - 6x + 8 = 0

Consider the factors of the constant term (+ 8) which sum to give the coefficient of the x- term (- 6)

The factors are - 2 and - 4 , since

- 2 × - 4 = + 8 and - 2 - 4 = - 6 , then

(x - 2)(x - 4) = 0

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x - 4 = 0 ⇒ x = 4

The justification (D) shading is to the left because (0, 0) does not satisfy the inequality option (D) is correct.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.

We have inequality:

[tex]\rm x+3.5 < \dfrac{1}{10}(y-2)^2[/tex]

If plug (0, 0)

0 + 3.5 < 4/10

Which is not true.

Thus, the justification (D) shading is to the left because (0, 0) does not satisfy the inequality option (D) is correct.

Answer:2 yds and h

Step-by-step explanation:

The volume of the new cylinder will be equal to 40.96 cubic centimeters.

The amount of space inside a cylinder is its volume. You can find it by dividing the base area by the height.

The formula to calculate the volume of the cylinder is given below:-

V = πr²h

Given that volume of a cylinder is 80 cubic centimeters. The diameter and height of the cylinder is multiplied by 4/5. The new volume will be:-

Vi= πr²h = 80 cubic centimeters.

The new volume will be calculated as:-

Vn= π (4/5r)²(4/5)h

Vn = (64 / 125 )  πr²h

Vn = (64 / 125 ) x Vi

Vn = (64 / 125 ) x 80

Vn = 40.96 cubic centimeters.

Therefore, the volume of the new cylinder will be equal to 40.96 cubic centimeters.
