How high the football gets is a function of the maximum height of the ball

The football goes 40.313 ft high

The equation that models the height of the ball is given as:

[tex]h(t) = -5t^2 +27.5t+2.5[/tex]

Differentiate the function

[tex]h'(t) = -10t +27.5[/tex]

Set to 0

[tex]-10t +27.5 = 0[/tex]

Collect like terms

[tex]10t =27.5[/tex]

Divide by 10

[tex]t =2.75[/tex]

Substitute 2.75 for t in [tex]h(t) = -5t^2 +27.5t+2.5[/tex] to calculate how high the ball get

[tex]h_{max} = -5 * 2.75^2 +27.5 * 2.75+2.5[/tex]

[tex]h_{max} = 40.3125[/tex]

Approximate

[tex]h_{max} = 40.313[/tex]

Hence, the football goes 40.313 ft high

Given :

Casey's company charges , C = $300.

In summer special, Casey offers customers a trade discount of 25%.

To Find :

Charges during summer.

Solution :

Let, x is the amount of charges they take during summer.

Casey offers customers a trade discount of 25%.

[tex]x =300(1-\dfrac{25}{100})\\\\x=300(1 - 0.25)\\\\x=300(0.75)\\\\x=\$225[/tex]

Therefore, amount of charges during summers are $225.

Hence, this is the required solution.

Answer:

Step-by-step explanation:

6y+4-3y=-5+y+17

6y-3y-y= -5+17-4

2y=8

y=4

Answer:

y = 4

Step-by-step explanation:

6y + 4 - 3y = -5 + y + 17

First, we have to combine like terms on each side of the equation:

3y + 4 = y + 12

Then, we have to combine the terms from both sides of the equation:

3y + 4 = y + 12

      -4          -4

3y = y + 8

-y    -y

2y = 8

Then, we divide so we only have y on the left side:

2y = 8

/2     /2

y = 4

4. I used the formula -b/2a to find the x-value of the vertex. I got 0 (there is no b) and then I subbed it into the function and y = 9. Hence the vertex of the first function is (0,9) which is the same as the second function

5. The vertex of the f(x) is (-3, -3) and the vertex of g(x) is (3, 12). To find the difference you would do 12 - (-3), which would become 12 + 3 = 15

Answer:

After the December 7, 1941, Japanese attack on the American naval fleet at Pearl Harbor, Hawaii, the U.S. was thrust into World War II (1939-45), and everyday life across the country was dramatically altered. Food, gas and clothing were rationed. Communities conducted scrap metal drives. To help build the armaments necessary to win the war, women found employment as electricians, welders and riveters in defense plants. Japanese Americans had their rights as citizens stripped from them. People in the U.S. grew increasingly dependent on radio reports for news of the fighting overseas. And, while popular entertainment served to demonize the nation’s enemies, it also was viewed as an escapist outlet that allowed Americans brief respites from war worries.

Step-by-step explanation:

as x+6 is the quotient, you need to use -6

-6 |  4   -3   +5       6

x         -24  +162 -1002

add

       4  -27  167  -996

f(x)= 4x^2 -27x +167 - 996/(x+6)

Lets check

(x+6)(4x^2 -27x +167)= 4x^3 -27x^2 +167x + 24x^2 - 162x + 1002 =

= 4x^3 - 3x^2 +5x +1002

1002-996= 6

So we have the correct solution: 4x^2 -27x +167 - 996/(x+6)

Answer:

w = 99 pounds

Step-by-step explanation:

The problem states that Mary's weight is given by the equation:  

w = 92 + g - 1

I believe the "-1" should be "-x."  -1 would mean that Mary lost 1 pound.  But we know that Mary lost 8 pounds, which is designated as x.

The correct equation is:

w = 92 + g - x

============

Using the correct equation, and g=15 and x=8, Mary's new weight is:

w = 92 + 15 - 8

w = 99 pounds

Answer:

slope is 3/2

Step-by-step explanation:

you can find slope by comparing the vertical height / horizontal height of two points on the line

for example, we can use points (20,0) and (40,30)

vertical height is 30 minus 0 which is 30

horizontal height is 40 minus 20 which is 20

so slope is 30/20 or 3/2

Answer:

[tex](x+11)(x-7)[/tex]

Step-by-step explanation:

To factorize [tex]x^2+4x-77[/tex]

[tex]\textsf{for} \ ax^2+bx+c \ \textsf{find} \ v, w \ \textsf{such that} \ v \cdot w=a \cdot c \ \textsf{and} \ v+w=b\\ \textsf{ and group into} \ (ax^2+vx)+(wx+c)[/tex]

[tex]a \cdot c=1 \cdot -77=-77[/tex]

[tex]b=4[/tex]

Therefore, the 2 numbers that multiply together to give -77 and add together to give 4 are:  11 and -7

[tex]\implies x^2+11x-7x-77[/tex]

[tex]\implies (x^2+11x)+(-7x-77)[/tex]

Factor the parentheses:

[tex]\implies x(x+11)-7(x+11)[/tex]

Factor out the common term [tex](x+11)[/tex]:

[tex]\implies (x+11)(x-7)[/tex]

[tex]\\ \rm\rightarrowtail x^2+4x-77[/tex]

[tex]\\ \rm\rightarrowtail x^2+11x-7x-77[/tex]

[tex]\\ \rm\rightarrowtail x(x+11)-7(x+11)[/tex]

[tex]\\ \rm\rightarrowtail (x-7)(x+11)[/tex]

Answer:

[tex]Cost= \$47[/tex]

Step-by-step explanation:

Given

Vertices: (−1, 5), (4, 2), and (9, −4)

Cost per foot = $8

Required

Determine the cost of fencing (-1, 5) and (4, 2)

First, we need to determine the distance between (-1, 5) and (4, 2)

Distance, d is calculated as follows:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

Where

[tex](x_1,y_1) = (-1, 5)[/tex]

[tex](x_2,y_2) =(4, 2)[/tex]

So, we have:

[tex]d = \sqrt{(4 - (-1))^2 + (2 - 5)^2}[/tex]

[tex]d = \sqrt{(4 +1))^2 + -3^2}[/tex]

[tex]d = \sqrt{5^2 + -3^2}[/tex]

[tex]d = \sqrt{25 + 9}[/tex]

[tex]d = \sqrt{34}[/tex]

[tex]d = 5.83095189485[/tex]

[tex]d = 5.831[/tex] -- Approximated;

If the cost of 1 foot is $8.

5.831 feet will cost:

[tex]Cost= 5.831 * \$8[/tex]

[tex]Cost= \$46.648[/tex]

[tex]Cost= \$47[/tex] -- Approximated

The interest rate Cindy will be charged is approximately 8.5%.

The money factor or lease factor is a method for determining the financing charges on a lease with monthly payments. The money factor can be translated into the annual percentage rate (APR) by multiplying the money factor by 2,400.

Money factor = 0.00354

So, the interest rate Cindy will be charged = 2400* 0.00354

The interest rate Cindy will be charged = 8.496% ≈8.5%

Therefore, The interest rate Cindy will be charged is approximately 8.5%.
