Simple as subbin' in -5 for x.
f(-5) = -(-5)² - 2(-5) + 1
= -25 + 10 + 1
= -14
Answer:
Hi,
Step-by-step explanation:
PR²=PQ²+QR²-2*PQ*QR*cos(51°)
=15²+12²-2*15*12*cos(51°)
=142,444659....
PR=11.9350...
PQ²=QR²+PR²-2*QR*PR*cos(R)
cos(R)=(12²+142.444...-15²)/(2*12*11.9350...)=0,21451112....
angle R=77,61315...°≈77.6°
angle P=180°-51°-77.6°≈51,4°
<span><u>Answer </u>
Skew lines do not lie on the same plane.
<u>Explanation
</u>
Skew line are lines that do not meet yet they are not parallel. Skew line are such that when translated they make an angle with each other. So they cannot be said to be parallel.

Answer:
<KJM and <IJH
Step-by-step explanation:
Those are supplementary angles because when put together they give you an angle of 180°
Answer:
Your answer would be V = 181472.0 m³ or 5671/1 m³
Step-by-step explanation:
You can divide 181472 by 32 to get 5671, and it can't be divided anymore so the answer is 5671/1 m³.
Hope this helps.
