Answer:
Yes, the student is correct
Step-by-step explanation:
Given
Required
Does it represent the x intercept
At the x intercept, the value of x is 0.
So, the function becomes
can be compared to
Hence, the student is correct
perimeter = 2L+2w
from the problem L = 1/5w-2
so perimeter = 2(1/5w-2) +2w
= 2/5w-4 +2w
=12/5w-4
without seeing your choices it should be similar to this
Answer:
-7
Step-by-step explanation:
-3x-5=16
-3x-5+5=16+5
-3x=21
-3x/-3=21/-3
x=-7
The third option has the highest value
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
