10/2 =5
Step-by-step explanation:
You need to use trigonometric stuff here. Since you're given the hypotenuse and an angle you can plug that right into an equation.
Recall that sin is opposite over hypotenuse and cos is adjacent over hypotenuse.
Now that you know the opposite side (DC) you can use tan, too, but I'm going to use cos.
This is the adjacent side (BC). I put it in its exact value, but in decimal form it's ≈12.124.
Now you can do the perimeter:
Your answer is the 38.2
Answer:
B
Step-by-step explanation:
The definition of a function is that any input will only have one output. Here, the input is the number of years, and the output is the value of the car. We know this because the question is asking why the value of the car is a function of the number of years. Therefore, based on the number of years, the value of the car is given.
Going back to the definition of a function, we can apply this year to say that any number of years will only have one car value. Another way to say this is that each time is associated with exactly one car value.
Vcylinder=hpir^2
VA=hpi6^2
VB=hpi(6/2)^2=hpi3^2
A times ?=B
?= a fraction
hpi6^2 times ?=hpi3^2
divide both sides by hpi
6^2 times ?=3^2
36 times ?=9
divide both sides by 36
?=9/36
?=1/4
1/4 of A is B
