Ten members of the academic team went to a local restaurant after their contest. Each meal combo that came with soda cost $6.75,
Aneli [31]

Answer:

7 ordered with Soda;

3 ordered with water

Step-by-step explanation:

Given

m \to With water

n \to With Soda

So:

m + n =10 --- total

5m + 6.75n = 62.25 -- cost

Required

Find m and n

m + n =10

Make m the subject

m = 10 - n

Substitute m = 10 - n in 5m + 6.75n = 62.25

5(10-n) +6.75n = 62.25

50-5n +6.75n = 62.25

Collect like terms

-5n +6.75n = 62.25 - 50

-5n +6.75n = 12.25

1.75n = 12.25

Solve for n

n = 12.25/1.75

n = 7

m = 10 - n

m = 10 - 7

m =3

4vir4ik [10]

Hi,

During halftime of a soccer game, a slingshot launches T-shirts at the crowd. A T-shirt is launched from a height of 5 feet with an initial upward velocity of 72 ft. Per second. The T-shirt is caught 34 feet above the field. How long will it take the T-shirt to reach its maximum height? What is the maximum height? What is the range of the function that models the height of the T-shirt over time.

<u>Write the general equation that represents height of the t-shirt as a function of time. </u>

f(t) = -16t^{2} + 72t + 5

2. <u>What is the maximum height of the t-shirt?</u>

<u />t = \frac{-72}{2(-16)} = 2,25                         f(2,25) = -16(2,25)^{2} + 72(2,25) + 5

                                                                = 86 feet

1. <u>How long will it take the t-shirt to reach its maximum height?</u>

2,25 secondes

3. <u>The range describes which values of the graph? What would the range of this graph be? (Write in inequality and interval notation).</u>

height (y)

5 ≤ y ≤ 86        [ 5,86 ]
