Answer:
Step-by-step explanation:
The question is incomplete. Find the complete question a=below;
A golf ball is hit with a club from the ground on a flat surface. The height of the ball, h(t), in feet, t seconds, after it was hit can be modeled by the function h(t)=40t-16t2. After how many seconds does the golf ball strike the ground?
The ball strikes the ground when the height h(t) = 0. To get the time wen the golf ball strikes the ground, we will substiute h = 0 into the modeled equation and calculate t as shown;
h(t)=40t-16t2
0 h(t)=40t-16t2
40t-16t² = 0
add 16t² to both side
40t-16t²+16t² = 0+16t²
40t = 16t²
40 = 16t
divide both sides by 16
t = 40/16.
t = 2.5secs
Hence the golf ball hit the ground after 2.5secs
Answer:
when the ball is hit as 0 second it has a height of 0 feet (because it hasnt done anything yet). The ball's height increases until it reaches its maximum height of 40 feet after 1.25 seconds (40t= 2.5/2). The balls height then decreases until it reaches 2.5 seconds after it was hit.

Is the sum of √16 and 1.5 rational or irrational?" Justify and explain your answer.
Answer:
Rational
Step-by-step explanation:
The square root of 16 is 4, and 4 + 1.5 is = to 5.5. An irrational number is defined as infinite and never-ending. Since 5.5 is not infinite, we can conclude that it isn't irrational.

A movie, including the previews, is 2 hours and 40
minutes long. If the previews last 20 minutes, what
fraction of the total time is the actual movie?
Answer:
7/8
Step-by-step explanation:
Given the length of the actual movie time and the length of the total movie time, the actual movie is 7/8 of the total movie time.
What fraction of the total time is the actual movie?Given the data in the question;
Total time of the movie is 2 hours and 40 minutes = 160 minutes
Preview time is 20 minutes
Now time of the actual movie will be;
Total time of the movie - Preview time
2 hours and 40 minutes - 20 minutes
160 minutes - 20 minutes
Time of the actual movie is 140 minutes
Now we get the fraction
Time of the actual movie / Total time of the movie
= 140 minutes / 160 minutes
= 14/16
= 7/8
Therefore, given the length of the actual movie time and the length of the total movie time, the actual movie is 7/8 of the total movie time.

what is 4.5x10^-6 in standard notation?
The number 4.5x10⁻⁶ can be expressed in standard notation as decimal 0.0000045.
In scientific notation, numbers are expressed as a decimal number between 1 and 10 multiplied by a power of 10. In this case, 4.5 is the decimal number and 10⁻⁶ represents the power of 10.
To convert this to standard notation, we move the decimal point six places to the left to match the negative exponent of 10⁻⁶. This gives us:
0.0000045
In standard notation, this number is written as 0.0000045, where the zeros after the decimal point indicate the value of the number in the place of each digit. The last non-zero digit in this case is 5, which is in the sixth decimal place.

what is the distance between 8 1/2 and 4 1/2?
Answer:
4
Step-by-step explanation:
just subtract 4.5 from 8.5
A fraction is a way to describe a part of a whole. The distance between 8 1/2 and 4 1/2 is 13 feet.
What is a Mixed Fraction?A mixed fraction is a fraction that contains a whole number and a fraction whose denominator is greater than the numerator. A mixed fraction can be converted as,
2 1/2 = (2×2 + 1)/2
= 5/2
= 2.5
Now, the distance between them
Distance = (8 1/2) feet + (4 1/2) feet
Converting Mixed fractions to fractions,
(8×2 + 1)/2 + (4×2 + 1)/2
= 17/2 + 9/2
= (17+9)/2
= 26/2
= 13 feets
Hence, the distance between 8 1/2 and 4 1/2 is 13 feet.

How do I solve this and make it the most simplified it can be?
Answer:
[tex]m = \frac{5}{2} [/tex]Step-by-step explanation:
[tex]\frac{3}{2} + \frac{2m}{9} = \frac{37}{18}[/tex]
Multiply through by 18 to eliminate the fraction
That's
[tex]18 \times \frac{3}{2} + 18 \times \frac{2m}{9} = 18 \times \frac{37}{18} \\ 27 + 4m = 37[/tex]
Subtract 27 from both sides
That's
[tex]27 - 27 + 4m = 37 - 27 \\ 4m = 10[/tex]
Divide both sides by 4
That's
[tex] \frac{4m}{4} = \frac{10}{4} [/tex]

How do you figure this equation out?
4r + 7 = 35
Answer:
r = 7
Step-by-step explanation:
Step 1: Write out equation
4r + 7 = 35
Step 2: Subtract 7 on both sides
4r + 7 - 7 = 35 - 7
4r = 28
Step 3: Divide both sides by 4
4r/4 = 28/4
r = 7
Solve 4r+7=35
4r=35-7
4r=28
r=7

14. 9(y - 4) - 7y = 5(3y - 2
step by step please
Answer:
y=-2
Step-by-step explanation:
9(y−4)−7y=5(3y−2)
(9)(y)+(9)(−4)+−7y=(5)(3y)+(5)(−2)
9y+−36+−7y=15y+−10
(9y+−7y)+(−36)=15y−10
2y+−36=15y−10
2y−36=15y−10
Step 2:
2y−36−15y=15y−10−15y
−13y−36=−10
Step 3:
−13y−36+36=−10+36
−13y=26

y=-2
Answer:
y=-2
Step-by-step explanation:
Simplifying
9(y + -4) + -7y = 5(3y + -2)
Reorder the terms:
9(-4 + y) + -7y = 5(3y + -2)
(-4 * 9 + y * 9) + -7y = 5(3y + -2)
(-36 + 9y) + -7y = 5(3y + -2)
Combine like terms: 9y + -7y = 2y
-36 + 2y = 5(3y + -2)
Reorder the terms:
-36 + 2y = 5(-2 + 3y)
-36 + 2y = (-2 * 5 + 3y * 5)
-36 + 2y = (-10 + 15y)
Solving
-36 + 2y = -10 + 15y
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-15y' to each side of the equation.
-36 + 2y + -15y = -10 + 15y + -15y
Combine like terms: 2y + -15y = -13y
-36 + -13y = -10 + 15y + -15y
Combine like terms: 15y + -15y = 0
-36 + -13y = -10 + 0
-36 + -13y = -10
Add '36' to each side of the equation.
-36 + 36 + -13y = -10 + 36
Combine like terms: -36 + 36 = 0
0 + -13y = -10 + 36
-13y = -10 + 36
Combine like terms: -10 + 36 = 26
-13y = 26
Divide each side by '-13'.
y = -2
Simplifying
y = -2
