F(x)=-2e^x
x=3
f(3)=-2e^3
pemdas so exponents first
e^3
e=2.718281828454590
cube that
20.0855
now we have
-2 times 20.0855=-40.1711
answer should be -40.1711
(I see what you did wrong, if -6=-2 times e^3, divide -2, 3=e^3, maybe you just put -2 times 3 by mistake)
Answer:
The first answer is wrong the real answer is 180
Step-by-step explanation:
A straight angle looks like a straight line. It has an angle measurement of 180 degrees. Straight angles can be composed of several angles, as long as the angles add up to 180 degrees.
Answer:
F(4)= 2
Step-by-step explanation:
F(x) = 2x^2 − 30, find f(4).
F(4)= (2)(4)^2 - 30
F(4)= (2)(16) - 30
F(4)= 32 - 30
F(4)= 2
1) Lets say there is point A that is perpendicular to WX and has W in it.
2) To find YA, we have to 19 - 11 = 8
3) Do Pythagorean theorem to find WY, which is:

This is equal to
42.76 in decimal
