David kicks a ball off the ground. After t seconds, it’s height, h (in feet), is given by the formula h=-16t^2+80t. How many seconds does the ball reach its maximum height? What is the maximum height reached by the ball?
Answer:
The ball reaches its maximum height at 2.5 seconds
The maximum height is 100 feet
Step-by-step explanation:
Maximum Value of Functions
We use the derivative of a function to find its maximum or minimum value over a given interval.
Given a function y=f(x), the first derivative criterion establishes if x=a is such that:
f'(a)=0, and f''(a) < 0 then x=a is a maximum of f.
The height h in feet of a ball after t seconds is:
[tex]h(t)=-16t^2+80t[/tex]
Find the first derivative:
[tex]h'(t)=-32t+80[/tex]
Equate to 0:
[tex]-32t+80=0[/tex]
Subtract 80:
[tex]-32t=-80[/tex]
Divide by -32:
[tex]t = -80 / (-32) = 2.5[/tex]
t=2.5 seconds
Find the second derivative:
h''(t)=-32
Since h''(t) is always negative, then
The ball reaches its maximum height at 2.5 seconds
To find the value of the maximum height, substitute t=2.5 into the function:
[tex]h(2.5)=-16(2.5)^2+80*2.5=-100+200 = 100[/tex]
The maximum height is 100 feet
Solve the equation.
4n−18=5
Answer:
n = 5.75
Step-by-step explanation:
4(5.75) - 18 = 5
4(5.75) = 23
23 - 18 = 5
Therefore, n = 5.75.

Malcolm and Theo's families are both traveling to the same vacation resort.
The equation d = 65t models the distance, d, that Malcolm's family travels after t hours.
The graph below shows the relationship between the distance and the amount of time that Theo's family traveled.
Answer:
Malcom's family travel 15 miles per hour faster than Theo's
Step-by-step explanation:
See attachment for complete question
Given
Malcom's Family:
[tex]d = 65t[/tex]
To determine the equation of Theo's family, we refer to the attached graph.
From the graph:
[tex]t = 1; d = 50[/tex]
[tex]t = 2; d = 100[/tex]
First, we determine the slope, m:
[tex]m = \frac{d_2 - d_1}{t_2 - t_1}[/tex]
[tex]m = \frac{100 - 50}{2- 1}[/tex]
[tex]m = \frac{50}{1}[/tex]
[tex]m = 50[/tex]
Next, we determine equation for Theo's family using:
[tex]d - d_1 = m(t - t_1)[/tex]
[tex]d - 50 =50(t - 1)[/tex]
[tex]d - 50 =50t - 50[/tex]
Add 50 to both sides
[tex]d - 50 +50=50t - 50 + 50[/tex]
[tex]d =50t[/tex]
So, we have the following:
[tex]d = 65t[/tex] --- For Malcom's family
This implies that Malcom's family travel at 65 miles per hour
[tex]d =50t[/tex] --- For Theo's family
This implies that Theo's family travel at 50 miles per hour
The difference between this rates is:
[tex]Rate = 65t - 50t[/tex]
[tex]Rate = 15t[/tex]
Which implies that Malcom's family travel 15 miles per hour faster than Theo's

2 + 3( 4x + 5) = -53
Answer:
x=-35/6
Step-by-step explanation:
2 + 3( 4x + 5) = -53
subtract 2 from both sides= 3(4x+5)=-55
divide both sides by 3 = 4x+5=-55/3
subtract both sides by 5 = 4x=-70/3
divide both sides by 4 = x=-35/6
x=-35/6 is your final answer
Answer:

Answer:
([tex]\frac{2}{3}[/tex], 2 )
Step-by-step explanation:
Given the 2 equations
3x + [tex]\frac{1}{2}[/tex] y = 3 → (1)
6x - y = 2 → (2)
Multiplying (1) by - 2 and adding to (2) eliminates the term in x, that is
- 6x - y = - 6 → (2)
Add (2) and (3) term by term to eliminate x
- 2y = - 4 ( divide both sides by - 2 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (2)
6x - 2 = 2 ( add 2 to both sides )
6x = 4 ( divide both sides by 6 )
x = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]
Solution is ( [tex]\frac{2}{3}[/tex], 2 )

The density of a certain material is such that it weighs 4 kilograms per cup of volume. Express this density in pounds per liter. Round your answer to the nearest tenth.
Pls help
Answer: 37.2 pounds per liter
Step-by-step explanation:
The density of the material of 4 kg/cup on converting it into pounds per litre will be 37.2 lbs/lt.
Given that, the density of a certain material is such that it weighs 4 kilograms per cup of volume.
What are derived units?Defining a derived unit is the process of deriving a measurement unit from one or more of the seven base units of the international system of units (SI). There are two types of derived units: dimensionless and the product of base units.
Here it is given that, the density d of a certain material is 4 kilograms per cup of volume and it is finding the density of material in pounds per litre.
Now it is known that,
1 kg equals 2.2 pounds
Now, 1 cup of volume equals 0.237 lt.
Converting the density d of material in pounds per litre and rounding it to the nearest tenth:
d=4 kg/cup
=4×2.2/0.237
=37.13≈37.1 pounds/lt
Therefore, the density of the material of 4 kg/cup on converting it into pounds per litre will be 37.2 lbs/lt.
