Mariana [72]
Knowing that a year later, the car is only worth 0.80 x, you can simplify that by stating that one year after purchase, the car is only worth 80% of its original purchase price.   
Another way of stating that is that the car lost 20% of its value of the course of one year.

Find the sum of the coefficients in the expansion of (x+1)^12
MariettaO [177]

Answer:

<h2>2¹²</h2>

Step-by-step explanation:

The sum of the coefficients in the expansion of (x+1)^12:

= 12C0 + 12C1 + 12C2 + . . . + 12C11 + 12C12

the formula says that this sum equal to 2¹².

Other examples

The sum of the coefficients in the expansion of (x+1)^3:

3C0+3C1+3C2+3C3

=8 = 2³

The sum of the coefficients in the expansion of (x+1)^4:

4C0+4C1+4C2+4C3+4C4

=16 = 2⁴

What is the radius of a circle with an area of 113.04 cubic inches? Use 3.14 for pi. Enter your answer in the box. in.
gizmo_the_mogwai [7]

Answer:

6 inches.  

Step-by-step explanation:

We have been given that area of a circle is 113.04 cubic inches and we are asked to find the radius of the circle.

We will use area of circle formula to find the radius of our circle.

\text{Area of circle}=\pi r^2

Upon substituting the area of given circle we will get,

113.04=\pi r^2

Substituting \pi=3.14 we will get,

113.04=3.14*r^2  

\frac{113.04}{3.14}=\frac{3.14*r^2}{3.14}  

36=r^2

Upon taking square root of both sides of our equation we will get,

r=\pm 6  

Since the radius of the circle can not be negative, therefore, the radius of circle will be 6 inches.
