Answer:
yes
Step-by-step explanation:
21−=2(2−)=2cos(−1)+2 sin(−1)
−1+2=−1(2)=−1(cos2+sin2)=cos2+ sin2
Is the above the correct way to write 21− and −1+2 in the form +? I wasn't sure if I could change Euler's formula to =cos()+sin(), where is a constant.

No. It is not true that =cos()+sin(). Notice that
1=1≠cos()+sin(),
for example consider this at =0.
As a hint for figuring this out, notice that
+=ln(+)
then recall your rules for logarithms to get this to the form (+)ln().
Answer:
E. The area to the left of 5.5 and D. The area to the right of 5.5
Step-by-step explanation:
Please see attachment .
In each of the problems, one of the equations is solved for y. Just plug in what y is equal to into the other equation.
1.) Plug -3 in for y.
-3 = 7x - 10
7x = 7
x = 1
2.) Plug -8 in for y.
-8 = -2x - 12
-2x = 4
x = -2
9.) Plug -8x in for y.
2x + 4(-8x) = 0
2x - 32x = 0
-30x = 0
x = 0
10.) Plug 2x in for y.
6x + 7(2x) = 20
6x + 14x = 20
20x = 20
x = 1
