Answer:
x ≈ 1.28
Step-by-step explanation:
I just took the exam:
Area of rectangle =(3x-1)(x+6), Area of circle = PI(x+1)^2. If you graph these and find where they intersect, you will get x ≈ 1.28.
I hope this helped! :)
Answer:
1200 feet
Step-by-step explanation:
given:
5 steps------> equivalent to 12 feet
1 step -------> equiv. to 12/5 feet
500 steps ----> equiv to (12/5) x 500 = 1200 feet
a. She divided the fraction strip into 8 parts
b. she converted 3.4 into a fraction with a numerator of 6.
c. she erased one eighths of the shaded area
Answer:
This should be A. -4 < x < 9.
Step-by-step explanation:
Domains are the x-values. So, you would have to look at the x axis to know your x values. I'm not a 100% sure if this is that correct answer, but here's the answer to what I know.
From your information
Let shorter base = h +3 and longer base = h + 7 where h is the height.
Formula for area of a trapezoid is
Substituting into the formula we get the following equation.
This is a quadratic equation which I will solve by factoring.
this is a useable answer (it's positive and length must be nonnegative)
can't use this answer
so shorter base = 10 + 3 = 13 yards and longer base = 10 + 7 = 17 yards
