Answer:
p=1, q=5. (1, 5).
Step-by-step explanation:
8p+7q=43
2-7=-q
------------------
-q=-5
q=5
--------
8p+7(5)=43
8p+35=43
8p=43-35
8p=8
p=8/8=1

Answer:
The answer is 4 minutes
Step-by-step explanation:
I divided 825 by 3 and got 165. If you multiply 165 by all the factors, you get approximately 4 minutes. It's the closest. Try that one.
I assume you're asked to solve
4 cos²(<em>x</em>) - 7 cos(<em>x</em>) + 3 = 0
Factor the left side:
(4 cos(<em>x</em>) - 3) (cos(<em>x</em>) - 1) = 0
Then either
4 cos(<em>x</em>) - 3 = 0 <u>or</u> cos(<em>x</em>) - 1 = 0
cos(<em>x</em>) = 3/4 <u>or</u> cos(<em>x</em>) = 1
From the first case, we get
<em>x</em> = cos⁻¹(3/4) + 2<em>nπ</em> <u>or</u> <em>x</em> = -cos⁻¹(3/4) + 2<em>nπ</em>
and from the second,
<em>x</em> = <em>nπ</em>
where <em>n</em> is any integer.
Answer:
4 units
Step-by-step explanation:
You have a triangle. This means that the formula is 1/2 x b x h. So its 2 x 4 = 8. Then its 8 x 1/2 which gives you 4.
