Answer:
a. -2+6 (ends up at 4)
b -2+(-6) (ends up at -8)
Step-by-step explanation:
Answer:
The answer is 21
Step-by-step explanation:
No it would be Pi *r *r because the r is to the power of 2
Answer:
<h2>f(-2) = 13</h2>
Step-by-step explanation:
f(x) = x² - 2x + 5
Yo find f(-2) substitute the value of x that's - 2 into f(x) that is for every x in f (x) replace it with - 2
So we have
f( - 2) = (-2)² - 2(-2) + 5
= 4 + 4 + 5
= 8 + 5
We have the final answer as
<h3>f(-2) = 13</h3>

Below represents the proof that the quadrilateral QRST is a parallelogram
<h3>How to prove that QRST is a parallelogram?</h3>
The coordinates are given as:
Q = (-1,-1)
R = (2,9)
S = (-4,5)
T = (-7,-5)
Calculate the length of each side using:

So, we have:




The above computations show that opposite sides are equal.
Next, we determine the slope of each side using:

So, we have:




The above computations show that opposite sides are parallel, because they have equal slope
Hence, the quadrilateral QRST is a parallelogram
