A. Mars 37.7% and moon 16.6%.
b. not 100% sure, but could be y=.377x and y=.166x
c. 29.88
d. 425.52
Answer:
Your expression would be 9x + 3y
Step-by-step explanation:
Coefficients with the same variables can be added together
Answer:
The antiderivative is .
Step-by-step explanation:
Antiderivative F(x)
This is the integral of
So
F′(x) = f(x) = 6 + 24x^3 + 18x^5
Then:
F(1)=0
when . We use this to find K.
Thus
The antiderivative is .
Answer:
Step-by-step explanation:
Circumference is the perimeter of a circle. It can be found using the formula:
However, we are given the radius.
- The radius measures from the center to the edge of the circle.
- The diameter measures from edge to edge through the center.
- So, the diameter is twice the radius, or d=2r
The formula can be rewritten as:
We know the circumference is 25.12 inches.
Let's round pi to 3.14
We want to solve for the radius, so we must isolate it.
Divide both sides by 3.14 because the inverse of multiplication is division.
Divide both sides by 2.
The radius of the disc is <u>4 inches.</u>
