This is called a literal equation, or an equation with multiple variables. You solve it the same as you solve any other equation, but the variables stay there the whole time.
If they want "r" to be the subject, then they want you to solve for r. This means that you need to get the variable r by itself on one side of the equation, but still have the equation be equivalent to it original form.
I'm going to show you, in steps, how to solve this problem:
<span>V=πr²h
Divide both sides by "</span>π²h<span>"
</span>V/π²h=(πr²h)/<span>π²h
</span>
V/(π²h)=r
Your answer is r=V/<span>π²h</span>
Answer:
1. y = 4x - 4
2. y = x + 2
3. y = -2x - 4
4. y = -x + 2
Step-by-step explanation:
Slope-intercept form is y = mx+b. As we know, m is the slope and b is the y-intercept. We need to find the slope and y-intercept and put them in the equation. Slope is rise over run, so we just count up then over until we get to an intersection. For the y-intercept, we look where the line crosses the y-axis.
Answer:
0.5
Step-by-step explanation:
The average rate of change (m) on the interval [a, b] is ...
m = (f(b) -f(a))/(b -a)
On the interval [-2, 3], the average rate of change is ...
m = (5 -2.5)/(3 -(-2)) = 2.5/5 = 0.5
Answer:
<u><em>He made a loss of 6.67%</em></u>
Step-by-step explanation:
Loss percentage = 
Loss = 50
Cost price = 750
Hence, Loss percentage=
=
= 6.66 %
He made a loss of 6.6666%.
This amount can be rounded up to 6.67%
