The length of the windshield wiper to the nearest inch is 24 inches

<h3>How to calculate the area of a sector</h3>

The formula for calculating the area of a sector is given as:

A = r²β/2

r is the length of the wiper

β is the subtended angle

Given the following

A = 500.3 square in

β = 98 degrees = 98pi/180 = 49pi/90

Substitute

500.3 =  r²49pi/180
500.3 = 153.86r²/180

153.86r² = 90054
r² = 585.298

r = 24.19

Hence the length of the windshield wiper to the nearest inch is 24 inches

What are the zeros of the function below?
Ivan
When you want to find zeros of rational expression you need to find at which points numerator is equal to zero. In this case, we have the product of three expressions.
x(x-1)(x+11)=0
A product is equal to zero whenever one of the factors is equal to zero. 
That means that zeros of our functions are:
1)x=0
2)x-1=0
x=1
3)x+11=0
x=-11
The final answer is a. Function has zeros at (0, 1, -11).

An online video store charges $24 please help
mr Goodwill [35]

Answer:

B. 24d + 4; $76

Step-by-step explanation:

Part 1: If the online store charges $24 per DVD, this is the same as saying "24 multiplied by the number of DVDs bought".

It's given that "d" represents the number of DVDs

  • So the first part of the variable expression is: 24d

If the online store also charges an additional $4 per <em>order,</em> that means that it's only $4 extra for the whole order. NOT per DVD you buy.

  • Result: 24d + 4

Part 2: If someone were to buy 3 DVDs, that would mean that d = 3.

To find the total cost, substitute 3 for d into the expression.

  • 24d + 4
  • 24(3) + 4
  • 72 + 4 = 76
  • Result: $76
