Answer:
No
Step-by-step explanation:
x = 0
y = 2
y = 7x
2 = 7(0)
2 ≠ 0
Answer:
The expression of h as function of x is h = 
Step-by-step explanation:
Given as :
The distance of blimp (AB) = 5500 feet
The slanted distance to the pagoda (BC) = d feet
The horizontal distance (AC) = h
Let the angle made between slanted distance and horizontal distance be Ф
So , cos Ф =
= 
And sin Ф =
= 
∵, cos²Ф = 1 - sin²Ф
So,
= 
Or,
=
Or, h² = d² - 5500²
∴ h = 
Or, h = 
Hence The expression of h as function of x is h =
Answer
Your answer should be 1/6 because you are dividing thing by the number.

Answer:
only -2 is in the domain
Step-by-step explanation:
For negative values under the sqrt, there is no real answer, hence
-2x ≥ 0
only for x=-2 this is the case.
The domain represents all the valid input values for x.
