The axis of symmetry would be x=0
The first choice if ()2 means to the power of two if not then it is none of them.
First
angle in front of c is 30°, so hypotenuse is equal to 2c
it's right triangle, so let's use Pythagorean theorem\
Second
b - the base of the triangle, angles at the base are equal ⇒ cathets are equal
it's right triangle, so let's use Pythagorean theorem
Alright, the first thing we should have to do is find the total cost per year of his insurance. To do that, we multiply $96.21 by the 12 months in a year to get $1154.52. This is the cost of his insurance per year.
Next, we need to find out how much his boss covers, which we know is 85% of the total cost. SO what we can do is multiply the yearly cost ($1154.52) by the percent his boss covers (.85) to get $981.342. This is how much his boss covers per year.
Lastly, to find out how much Derek pays for insurance yearly, we just need to subtract how much his boss pays ($981.342) from the total yearly cost ($1154.52), which leaves us with $173.178, which is how much Derek pays yearly for his insurance, which should be your answer.
Answer:
V=( 1/6 )* π * d³
Step-by-step explanation:
We khow that d= 2r⇒ r=d/2
- so r³= d³/8
- substitute r with d³/8
- V= (4/3)*π*(d³/8) = (4/3*8)*d³*π = (1/6 )* d³ *π
