A toy rocket is shot vertically into the air from a launching pad 7 feet above the ground with an initial velocity of 40 feet per second. The height h, in feet, of the rocket above the ground at t seconds after launch is given by the function h(t) = -16t²+40t+7. How long will it take the rocket to reach its maximum height? What is the maximum height?
The rocket reaches its maximum height at ___ second(s) after launch.
(Simplify your answer.)
The rocket reaches its maximum height at 1.25 second(s) after launch
The maximum height reached by the object is 32 feet.
Time to reach the maximum heightThe function is given as
h(t) = -16t² + 40t + 7
Differentiate the above function
So, we have the following representation
h'(t) = -32t + 40
Set to 0
-32t + 40 = 0
So, we have
32t = 40
Divide by 32
t = 1.25
Hence, the time is 1.25 seconds
The maximum heightIn (a), we have
t = 1.25
Substitute t = 1.25 in h(t) = -16t² + 40t + 7
h(1.25) = -16(1.25)² + 40(1.25) + 7
Evaluate
h(1.25) = 32
Hence, the maximum height is 32 feet

PLEASE HELP!!!:
A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 60% pure antifreeze. The company wants to obtain 180 gallons of a mixture that contains 20% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed?
The volume of premium antifreeze to be used is 60 gallons.
The volume of water to be used is 120 gallons
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Let the volume of 60% pure antifreeze be used to make 20% pure antifreeze.
= x gallons
The volume of 20% pure antifreeze = 180 gallons
For 60% pure antifreeze:
C₁ = 60% , V₁ = x gallons
For 20% pure antifreeze :
C₂ = 20% , V₂ = 180 gallons
Applying,
C₁V₁ = C₂V₂
60 × x = 20 × 180
x = 60 gallons
The volume of 60% pure antifreeze used = 60 gallons.
The volume of water to be used.
= 180 - 60 gallons
= 120 gallons
Thus,
The volume of premium antifreeze to be used is 60 gallons.

The total amount that Ms. Henderson must pay, given the penalty and the amount of taxes is $1, 478.75
How to find the total amount to be paid?First, find the total penalty on the taxes, to Ms. Henderson.
= Tax amount x Penalty percentage
= 1, 400 x 11 ¹ / ₄%
= $157.50
Because she paid in 6 months, but the penalty is for a year, Ms. Henderson's tax penalty is:
= 157.50 / 2
= $78.75

Solve the following quadratic equation by using the definition of a square root and write the solutions in simplified radical form. 3(y-7)² = 24
Answer:
y = 7 + 2√2, y = 7 - 2√2
Step-by-step explanation:
We need to solve for y to find the solutions of the quadratic equation:
3(y-7)^2 = 24
(y-7)^2 = 8
y-7 = ±√8 = ±√(4*2) = ±2√2
y = 7 + 2√2
y = 7 - 2√2
2√2 is the simplified radical form because 4 is the highest factor of 8 that is a perfect square.

The values of the composite functions f(g(x)) and g(f(x)) are (x/4) and (4x - 9),respectively.
We are given two functions, f(x) and g(x). The function f(x) is defined as 1/(x - 3). The function g(x) is defined as (4/x) + 3. A function connects an input to an output. It is analogous to a machine with an input and an output. And the outcome is somehow connected to the input. We need to find the composition of the functions.
The first composition is f(g(x)). The composite function is solved below.
f(g(x)) = f((4/x) + 3)
f(g(x)) = 1/([(4/x) + 3] - 3)
f(g(x)) = 1/(4/x)
f(g(x)) = x/4
The second composition is g(f(x)). The composite function is solved below.
g(f(x)) = g(1/(x - 3))
g(f(x)) = (4/[1/(x - 3)]) + 3
g(f(x)) = 4(x - 3) + 3
g(f(x)) = 4x - 12 + 3
g(f(x)) = 4x - 9

What is fundamental operation?
The fundamental operations are expressed in an order. Generally, the order will be in the format of “DMAS” where “D” stands for “Division”, “M” stands for “Multiplication”, “A” stands for “Addition”, “S” stands for “Subtraction”. This order is considered and sequentially performed from left to right.
Given, 1 box contains 10 bags of marbles
1 bag contains 10 marbles
Hence, 1 box contains 10 × 10 = 100 marbles.
Total numbers of marbles = 254
First condition is,
you can buy one box of marble = 1× 100 = 100
4 single marbles,
To find the number of bags, let x be the number of bag and one box contains 10 marbles,
therefore, x bags contains 10x marbles.
According to question,
100 + 4 +10x =254
104 +10x = 254
10x = 254- 104
10x = 150
x = 150÷10
= 15
Similarly in case of second condition,
2 boxes = 100×2 = 200
4 bags = 10× 4 = 40
Single marbles =?
200 + 40 +? =254

Solve 6x + 2 = 2x - 14
Answer:
x = - 4
Step-by-step explanation:
6x + 2 = 2x - 14 ( subtract 2x from both sides )
4x + 2 = - 14 ( subtract 2 from both sides )
4x = - 16 ( divide both sides by 4 )
x = - 4
We move all terms to the left:
6x + 2 - (2x - 14) = 0We get rid of the parentheses.
6x- 2x + 14 + 2 = 0We add all the numbers and all the variables.
4x + 16 = 0We move all terms containing x to the left hand side, all other terms to the right hand side

It is given that the function is,
I'm assuming that you mean the left and right Riemann sums with four equal subintervals when you refer to L4 and R4.
If so, then Δx = (8-0)/4 = 2, and f(x) = 2√x.
L4 = f(0)Δx + f(2)Δx + f(4)Δx + f(6)Δx
L4 =2[2√0 + 2√2 + 2√4 + 2√6]

Inverse of the given function y= 4x² +12x + 9 is given by x=(1/2) (√y -3).
Restricted domain is required to make function one -one so that its inverse exist.
Domain of the inverse function is y ≥ 0.
As given in the question,
Given function is equal to :
y = 4x² +12x + 9
Inverse of the function exist if and only if it is one to one.
x₁ ≠ x₂
⇒2x₁ +3 ≠ 2x₂ + 3
⇒f(x₁) ≠ f(x₂)
It is one -one. Inverse exist.
y = (2x +3)²
⇒ 2x + 3 = √y
⇒x = (1/2) ( √y -3)
Restricted domain of the inverse of the function is y ≥0.
