The equation to find volume is V=
r²h and you know all of your numbers other than h so you plug all that in. 100=3.14×2²×h → 100=3.14×4×h → 100=12.56×h → Divide 12.56 from both sides 100÷12.56=12.56×h÷12.56 → 7.96cm=h.

Answer:
<u>$600</u>
Step-by-step explanation:
The costs associated with the loan is:
$25 processing fee
1.5% interest, or, 1.5/100 = 0.015 of Loan
Total charge is given as $34, subtracting processing charge:
34 - 25 = $9 for interest
We now want:
What amount (loan amount we are looking for)'s 1.5% is $9??
We can say the amount to be "x", so we can write:
Hence, x is:
<u>Hence, Mr. Hernandez took a loan of $600</u>
Answer:
Step-by-step explanation:
First thing is to remember the sin ratio. It is, by definition, the side opposite over the hypotenuse of the reference angle. In QIII the side opposite the angle is -8 which is one of the legs of a right triangle, and the hypotenuse, which is always positive, is 10. That means that if we are going to find the cosine of the angle, we need the other leg of the triangle. Using Pythagorean's Theorem, we find that
and
and
so
a = 6. But because we are QIII, that value is negative, because x is negative in QIII.
That leg happens to be the side adjacent to the angle. The cosine of the angle is the side adjacent over the hypotenuse. So now that we have the side adjacent as -6, we can say that the cosine of the angle is -6/10.
