Ifp * (x) = 3x ^ 2 - 4 and r(x) = 2x ^ 2 - 5x + 1 . find value r(x + 2)
valina [46]

Answer:

<h2>          r(x+2) = 2x² + 3x - 1</h2>

Step-by-step explanation:

r(x) = 2x ^ 2 - 5x +1\\\\ r(x+2) = 2(x+2)^ 2 - 5(x+2) +1\\\\ r(x+2) = 2(x^2+4x+4) - 5x-10+1\\\\ r(x+2) = 2x^2+8x+8 - 5x-9\\\\ r(x+2) = 2x^2+3x-1

The local ice cream parlor sells an average of 11 milkshakes a day for $3.99
Greeley [361]

In a week, the parlor would make about $300 from milkshakes

The total amount the ice cream parlor makes in a week is dependent is the product of the number of days in a week , the number of milkshakes sold in a day and the price of a milkshake.

Total amount = number of milkshakes sold in a week x price of a milkshake

There are 7 days in a week, in a week the parlor would sell : 11 x 7 = 77 milkshakes

price of a milkshake = $3.99

77 x $3.99 = $307.23

lisov135 [29]

Answer:

24.997 cm

Step-by-step explanation:

Find the diameter:

7(2) = 14 cm

Find the circumference:

C = \pi d

C = \pi (14)

C = 43.988

Divide the circumference by 4:

43.988/4 = 10.997

(This is the length of the curved side)

Add length to the other 2 sides:

7 + 7 + 10.997 = 24.997
