Answer:
<h2>
</h2>
Step-by-step explanation:
s = πrl + πr²
First move πr² to the left side of the equation
We have
πrl = s - πr²
Divide both sides by πr to make l stand alone
That's
<h3>
</h3>
We have the final answer as
<h3>
</h3>
Hope this helps you
For easy answers, I find a graphing calculator very helpful.
(a) f is increasing on (-∞, -1) and on (9, ∞). You may be expected to use the union of these two intervals to describe "the interval on which f is increasing":
(-∞, -1) ∪ (9, ∞)
Look at the picture.

<h3>Answer: x ≥ -6 and x ≤ 5</h3>
Answer:
37 yw
Step-by-step explanation:
Answer:
1) x = 15
Step-by-step explanation:
We use the Pythagorean thm for these questions. Where a and b are the legs (So order doesn't matter), and where c is the hypotenuse
1)
a² + b² = c²
9² + 12² = x²
81 + 144 = x²
x² = 225
You square root each side so you can get rid of the exponent on x.
x = 15
