Answer:
h = 8.845 m
Step-by-step explanation:
The height h(t) of the football above the ground in meters t seconds after being punted is affected by gravity and by the punters kick, and can be represented as the difference of two functions:
[tex]a(t)=1.4t^2\\\\v(t)=12.1t+2.5[/tex]
We need to find h(t) such that, h(t)=v(t)-a(t)
So,
[tex]h(t)=12.1t+2.5-1.4t^2\\\\h(t)=-1.4t^2+12.1t+2.5[/tex]
It is a quadratic equation. When we solve it we get :
[tex]h(t)=8.845\ m, -0.2\ m[/tex]
Neglecting negative value,
h(t) = 8.845 m
So, the ball was at a height of 8.845 m when it was punted.

Answer:
C. 2.84%
Step-by-step explanation:
We are trying to figure out how much money will be made from the interest each year in percentage form so to set up the problem we need to first find the earnings from this year: 2,056.72 - 2,000 = 56.72
Then we will put 2,000 below that because that was the original full account deposit used to make the interest. 100 automatically goes on the other side because it is the full value of the percentage. Then solve the equation.
56.72 X
--------- = -------
2,000 100
To solve for X start by multiplying the diagonal numbers, in this case 56.72 and 100. Then divide by the remaining number, 2,000.

Select three sets of numbers that can be the side lengths of a right triangle
5, 6, 8
7, 24, 25
8, 10, 12
20, 21, 29
12, 35, 37
Answer:
4th choice, 20, 21, 29 would be the answer.
Step-by-step explanation:
Pythagorean Theorem: a^2 + b^2 = c^2
a= 20, b= 21, c= 29 ( c has to be the C, hypotenuse, because it is the longest)
therefore,
20^2 + 21^2 = 29^2
into
400 + 441 = 841,
which is true, makes the Pythagorean Theorem work.

Given :
Fitness center A has a $60 enrollment fee and costs $35 per month. Fitness center B has no enrollment fee and costs $45 per month.
To Find :
A) Identity the variables then write system of linear equations to represent the situation.
B) In how many months will both fitness centers cost the same? What will the cost be? Use the substitution method to solve this real-world application.
Solution :
a) Linear equation of center A :
F = 35x + 60 ...1)
Linear equation of center B :
F = 45x ...2)
b) Let, after n months both fitness centers cost the same fee :
So, 35m + 60 = 45m
10m = 60
m = 6 months
Putting value of m in equation 1) or 2) is :
F = (35×6) + 60 = $270 or F = 45×6 = $270 .
Therefore, the cost when they have same fee is $270 .
Hence, this is the required solution.

Set up and solve an equation to find the measure of each missing angle.
Answer:
<A = 76°
<B = 63°
<C = 41°
Plug in the value of x
<C = 34 + 7
<C = 41°
Step-by-step explanation:
[tex] 63 + (2x + 8) + (x + 7) = 180 [/tex] (sum of ∆)
Solve for x
[tex] 63 + 2x + 8 + x + 7 = 180 [/tex]
Add like terms
[tex] 78 + 3x = 180 [/tex]
Subtract 78 from each side
[tex] 78 + 3x - 78 = 180 - 78 [/tex]
[tex] 3x = 102 [/tex]
Divide both sides by 3
x = 34
<A = 2x + 8
Plug in the value of x
<A = 2(34) + 8 = 76°
<B = 63°
<C = x + 7
Plug in the value of x
<C = 34 + 7
<C = 41°

Joe concluded that the expression 3x + 15 + 2x is equivalent to the expression 5(x + 3). Which of these best explains how Joe reached his conclusion?
o dividing each term in the first expression by 3
combining like terms in the first expression and dividing each term by 3
combining like terms in the first expression and dividing each term by 5
subtracting 20 and applying the distributive property to the first expression
Answer:
The correct option is c. Combining like terms in the first expression and dividing each term by 5.
Step-by-step explanation:
Joe concluded that the expression [tex]3x+15+2x[/tex] is equivalent to the expression [tex]5(x+3)[/tex].
Let's analyze each option :
a. Dividing each term in the first expression by 3.
If we perform this operation it will lead us to :
[tex]\frac{3x+15+2x}{3}=x+5+\frac{2}{3}x[/tex]
And if we sum each term ⇒ [tex]x+5+\frac{2}{3}x=5+\frac{5}{3}x=5(1+\frac{1}{3}x)[/tex]
Which isn't equivalent to the expression [tex]5(x+3)[/tex]
b. Combining like terms in the first expression and dividing each term by 3.
If we perform this operation it will lead us to :
[tex]3x+15+2x=15+5x[/tex] ⇒
[tex]\frac{15+5x}{3}=5+\frac{5}{3}x=5(1+\frac{1}{3}x)[/tex]
Which isn't equivalent to the expression [tex]5(x+3)[/tex]
c. Combining like terms in the first expression and dividing each term by 5.
If we perform this operation it will lead us to :
[tex]3x+15+2x=15+5x[/tex] ⇒ Now if we divide each term by 5 and then we multiply the expression by 5 (in order to keep the equivalence) ⇒
[tex]\frac{15+5x}{5}=3+x[/tex]
And then we multiply by 5 to keep the equivalence ⇒
[tex]5(3+x)[/tex]
Finally, using commutative properties ⇒ [tex]5(3+x)=5(x+3)[/tex]
Which is the same expression that Joe found.
The correct option is c. Combining like terms in the first expression and dividing each term by 5.
Anyway, let's analyze option d. Subtracting 20 and applying the distributive property to the first expression :
[tex]3x+15+2x-20=-5+5x=5(-1+x)[/tex]
Which isn't equivalent to [tex]5(x+3)[/tex]
Answer: The correct option is c. Combining like terms in the first expression and dividing each term by 5.

The sum of three numbers is 27. The product of the first number times the third number is 56. The quotient of the second number divided by the first number is 1.5. If the first number is represented by x, the second number is represented by y, and the third number is represented by z, which of the systems of equations below can be used to determine the three numbers?
Answer:
The system of equations that can be used to determine the three numbers are equation 1 and 6
x + y + z = 27 ----- ( 1 )
37.33 x - 56 y + 0 = 0 ---- ( 6 )
Step-by-step explanation:
x + y + z = 27 ----- ( 1 )
x * z = 56 ------ ( 2 )
y / x = 1.5 -------- ( 3 )
from equation 3
x = y / 1.5 -------- ( 4 )
input equation 4 into ( 2 )
( y / 1.5 ) * z = 56
y * z = 37.33 ------ ( 5 )
from equation 5 ; z = 37.33 / y input back to equation 2
x ( 37.33 / y ) = 56
37.33 x = 56 y
37.33 x - 56 y + 0 = 0 ---- ( 6 )

Janice is preparing a recipe that calls for 3/4 cups of oil per serving. If janice needs to prepare 2 2/3 servings, how many cups of oil will she need?
Answer:
Janice will need 2 cups of oil.
Step-by-step explanation:
You know that Janice needs to prepare 2[tex]\frac{2}{3}[/tex] servings. A mixed number is a numerical way of representing a fraction greater than unity, that is, of representing fractions in which the numerator is greater than the denominator (improper fraction). To calculate the number of cups of oil needed, first it is convenient to transform the mixed number to an improper fraction. For that, the integer part is multiplied by the denominator and the numerator is added to it. The result obtained is the numerator of the improper fraction. The denominator is the same as that of the rational part of the mixed number.
In this case:
[tex]2\frac{2}{3} =\frac{3*2+2}{3} =\frac{8}{3}[/tex]
Knowing that the recipe calls for [tex]\frac{3}{4}[/tex] cups of oil per serving and Janice needs to prepare [tex]\frac{8}{3}[/tex] servings, you can apply the following rule of three: if [tex]\frac{3}{4}[/tex] cups of oil are required for 1 serving, [tex]\frac{8}{3}[/tex] servings how many cups of oil require?
[tex]cups of oil=\frac{\frac{8}{3}servings *\frac{3}{4}cups of oil }{1 serving}[/tex]
Solving:
cups of oil= 2
Janice will need 2 cups of oil.

The number of female nurses in a country can be predicted using the function f(t)=7,300 + 25t, where t is the number of years since 2000. The number of male nurses can be predicted using the function m(t) = 2,500(1.02)t, where t is the number of years since 2000. About how many years will it take before the number of male nurses is expected to exceed the number of female nurses?
It take 2 years for the number of male nurses to exceed the number of female nurses.
Given:
f(t) = 7,300 + 25t
m(t) = [tex]2,500(1.02)^t[/tex]
To find the value of t at which m(t) > f(t).
Let's set up the inequality:
[tex]2,500(1.02)^t > 7,300 + 25t[/tex]
We can start with t = 0 (year 2000) and increment t until m(t) exceeds f(t).
For t = 0:
m(0) = [tex]2,500(1.02)^0[/tex] = 2,500
f(0) = 7,300
Since m(0) < f(0), increase t.
For t = 1:
m(1) = [tex]2,500(1.02)^1 =[/tex] 2,550
f(1) = 7,300 + 25(1) = 7,325
Since m(1) < f(1), increase t as
For t = 2:
m(2) = [tex]2,500(1.02)^2 =[/tex] 2,601
f(2) = 7,300 + 25(2) = 7,350
Since m(2) > f(2), the number of male nurses is expected to exceed the number of female nurses after 2 years since 2000.
Therefore, it will take about 2 years.
