Answer:
33 by 45 meters
Step-by-step explanation:
The perimeter is twice the sum of adjacent side lengths, so the sum of the dimensions is 78 meters. If x is one of the dimensions, then 78-x is the other, and the area is their product:
x(78 -x) = 1485
Subtracting the left side, we get ...
x^2 -78x +1485 = 0
This can be graphed as ...
y = x^2 -78x +1485
and the zeros will reveal the dimensions.
The attached graph shows them to be ...
33 by 45 meters
so the sand pile looks more or less like the one in the image below.
let's check its circumference first. We know that dC/dt = 5π
hmmm when the circumference C = 8π, what's the radius "r"?
now let's take the derivative to the volume equation, and check what dV/dt is
Answer: 10 hours
Step-by-step explanation: so if you do 10 times 2.00 it equals 20 dollars or you can divide 20 and 2
Answer:
A) 7 is the greatest common factor of the expression.
B) factoring the expression we get
Step-by-step explanation:
We are given the expression:
Part A: What is the greatest common factor of the expression?
We need to find the greatest common factor of the expression.
The expression is divisible by 7
So, 7 is the greatest common factor of the expression.
Part B: Factor the expression
We need to factor the expression:
Taking 7 common:
So, factoring the expression we get
