Answer:
63 ft^2
Step-by-step explanation:
The hole is the rectangle minus the area of the triangle.
The area of the rectangle is
A =l*w
A = 12*6
=72
The area of the triangle is
A = 1/2 b*h
= 1/2 (3*6)
= 9
A rectangle - A triangle = A hole
72 - 9
63

Step-by-step explanation:
The answer is dhdt=325πmmin.
With related rates, we need a function to relate the 2 variables, in this case it is clearly volume and height. The formula is:
V=πr2h
There is radius in the formula, but in this problem, radius is constant so it is not a variable. We can substitute the value in:
V=π(5m)2h
Since the rate in this problem is time related, we need to implicitly differentiate wrt (with respect to) time:
dVdt=(25m2)πdhdt
In the problem, we are given 3m3min which is dVdt. So we substitute this in:
dhdt=3m3min(25m2)π=325πmmin
Inches can be measured with how long something is... Pounds can be measured with how much something weighs and cups with how much of something you need
Answer:
10.
Step-by-step explanation:
To find the distance between two numbers, subtract the two numbers. The absolute value of the difference is the distance.
The absolute value of -10 is 10.
Therefore, distance between -7 and 3 is 10.
