Answer:


Step-by-step explanation:
Given
The attached table

This represents an inverse function.
So, we look into x row for its value.
i.e.


Just like (a)
---- by looking into the x rows

So:


Answer:
The only multiples of 3 between 20 and 30 are 21, 24, and 27. Only 27 satisfies the condition that it is 3 times the sum of its digits.
Step-by-step explanation:
Answer:

Step-by-step explanation:
From the question we are told that
Angle 
Height of plane 
Generally the equation for the total distance flown is mathematically given by


Therefore total distance flown is

I'm assuming you mean
, not
, like your prompt suggests.
First, let's figure out what rule we can use. A likely noticeable one is the Power Rule, which says the following:
![\dfrac{d}{dx} [u^a] = a(u)^{a-1} du](https://tex.z-dn.net/?f=%5Cdfrac%7Bd%7D%7Bdx%7D%20%5Bu%5Ea%5D%20%3D%20a%28u%29%5E%7Ba-1%7D%20du)
Applying this, we can solve for the derivative:

While you can simplify the expression to your liking, I believe that this form is not overly complex and will thus leave it as is.
Thus, our answer is:

Answer:=3a+2b−21
Step-by-step explanation:
Let's simplify step-by-step.
3a+2b−7−4−10
=3a+2b+−7+−4+−10
Combine Like Terms:
=3a+2b+−7+−4+−10
=(3a)+(2b)+(−7+−4+−10)
=3a+2b+−21
