A football is punted from a height of 3.5 feet about the ground with an initial velocity of 45 feet per second. This situation can be represented by the function h(t)=- 16t^2 + 45t + 3.5, where t is the number of seconds elapsed since the football was kicked. If the football is caught at a height of 5.5ft on the ball's descent, how long was the football in the air? Round to the nearest hundredth.
*show me how you did it not just the answer please
The time at which the ball was in the air for the two cases of being dropped and being caught are respectively; t = 0.05 s and t = 2.77 s
What was the time of descent?We are given the function to represent the given height as;
h(t)= -16t² + 45t + 3.5
Since the football is caught at a height of 5.5ft on the ball's descent, then;
-16t² + 45t + 3.5 = 5.5
⇒ -16t² + 45t - 2 = 0
From online quadratic equation solver, we have;
t = 0.05 s and t = 2.77 s

which pair of ratios will make a proportion ?
Answer:
B. 3/5 and 9/15
Step-by-step explanation:
When looking for a proportion, you must look at a ratio that equals the same like:
1/2 = 2/4
You could see that I would just have to multiply or divide the numbers by 2.
So, that means they doubled.
3/5 = 9/15
How would you get 9 from 3? You would multiply by 3 to get 9.
Therefore, to check if it is a proportion, multiply with the same number you used to multiply the first number, which would be 3.
5 × 3 = 15.
Since 15 is written in the ratio, B would be the correct answer.
Therefore, B is the Correct Answer.

What is the simplified form of this expression?
(-x2 + x) + (4x2 − x − 1)
Explanation:
The x^2 terms add to -x^2+4x^2 = 3x^2
The x terms add to x+(-x) = x-x = 0x = 0
The constant -1 doesn't have anything to pair with it, so it just stays as is.
So overall we end up with 3x^2-1
18. Find the smallest angle in a triangle whose
sides are of length 3x, 4x and 6x.
Answer:
Step-by-step explanation:
The value of the smallest angle will be 26.38°.
Trigonometric Identities are equality statements that hold true for all values of the variables in the equation and that use trigonometry functions. There are numerous distinctive trigonometric identities that relate to a triangle's side length and angle.
Given that the sides are 3x,4x and 6x. The smallest angle will be calculated as below,
( 3x )² = ( 4x )² + ( 6x )² - 2 (4x) ( 6x)cosθ
9x² = 16x² +36x² - 48x²cosθ
9 = 52 - 48cosθ
cosθ = 43 / 48
θ = cos⁻¹ (43/48)
θ = 26.38°

u/3 + 29 =37
Answer:
u = 24
Step-by-step explanation:
Simplify both sides of the equation.
1/3u+29=37
Subtract 29 from both sides.
1/3u+29−29=37−29
1/3u=8
Multiply both sides by 3.
3*(1/3u)=(3)*(8)
u=24

The unit of measurement that is used for the water in the swimming pool is 2.3×10⁴ gallons.
What is the Units conversion?Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm,
though the real measurement is still the same the units and numerical values have been changed.
As it is given that the volume of the pool or the amount of water that is in the pool is equal to 2.3×10⁴ units.
We know that an average swimming pool has a volume of water that is in gallons, therefore, the unit of water that will be filled in the swimming pool will be equal to 2.3×10⁴ gallons.
Hence, the unit of measurement that is used for the water in the swimming pool is 2.3×10⁴ gallons.
