Answer

Write a function rule for the cost of n pounds and Find how much would 30 pounds of bananas cost .

To prove

First Case

First find the function rule for the cost of n pounds.

As given

Bananas are on sale for $0.40 a pound, and you have a coupon for $0.25 off your total purchase.

Here number of bananas = n pounds

Than the function becomes

C(n) =  0.4n - 0.25

Where C(n) is represented the total cost of the n pounds bananas.

Second Case

Find the cost for the 30 bananas .

Put n = 30 in the above equation.

C(30) =  0.4 × 30 - 0.25

          = $11.75

Therefore the option (C) is correct.

Graph the line. y=-4x+6 what the graph
Aloiza [94]
So the -4x is the M and then 6 is the B. So m is the slope and B is the y-intercept. The 6 goes on the y axis and the -4 will be how the line looks. It’ll be rise (-4) over run (1).

Each side of an equilateral triangle measure 11 centimeters. To the nearest tenth of an centimeter, what is the length of the al
Orlov [11]
The length of the altitude is 9.5 cm.

The altitude bisects the base of the equilateral triangle (this is because the two sides emerging from the vertex are equal).  This gives us a right triangle with leg 5.5 and hypotenuse 11.  We use the Pythagorean theorem:

5.5² + h² = 11²
30.25 + h² = 121

Subtract 30.25 from both sides:
30.25 + h² - 30.25 = 121 - 30.25
h² = 90.75

Take the square root of both sides:
√h² = √90.75
h = 9.5
