Answer:
look up how to find the slope and figure it out:)
Step-by-step explanation:
The use of the symbol • in <span>(p•q)(x)
is confusing.
You may be using it to indicate multiplication or to indicate composition of functions.
The operation and the results will be different in each case.
So, make sure that you interpret the problem correctly. I will do the problem for the two cases to help you.
1) if </span><span>• means multiplication:
</span>use the distributive property:
<span>(p•q)(x)
= (2x^2 - 4x) (x - 3) = 2x^3 - 6x^2 - 4x^2 + 12 x = 2x^3 - 10x^2 + 12x
2) if </span><span>• means compositon of functions:
=> </span><span>(p•q)(x)
= p [ q(x)] = p [ x -3] = 2 (x - 3)^2 - 4(x - 3)
= 2[x^2 - 6x + 9] - 4x + 12 = 2x^2 - 12x + 18 - 4x + 12 = 2x^2 - 16x + 30
Then, only make sure of the use of the symbol </span><span>• in (</span><span>p•q)(x)
, which you can find in the context of the question.</span>
(X-3)^2 /18 + (y+4)^2 / 27 =1
Answer:
12 foot.
Step-by-step explanation:
Given that,
A ladder leans a 15 foot ladder against a second story window.
The distance on the ground between the base of the ladder and the house is 9 feet.
We need to find the height of the ladder. Let it is h.
If we consider a right angles triangle such that 15 foot is hypotenuse, 9 feet is base, then we need to find the perpendicular height of the triangle. Using Pythagoras theorem to find it.
So, the height of the ladder that reaches the second story window is 12 foot.
