x=180°-(102°+43°)=180°-145°=35°
Answer:
Step-by-step explanation:
y=4 times 1/2 to the power of x can be written symbolically as
4 4
y = 4(1/2)^x. This is the same as y = ------- or y = -------- * 2^(-x)
2^x 1
This function is a "decaying exponential."
A suitable table follows:
x 4(2^[-x]) x y
0 4(2^0) (0, 4)
1 4(2^1) (1, 8)
2 4(2^2) (2, 16)
and so on.
16x-15-9x=13
7x-15=13
+15 +15
x=4
A. A Parsec
A parsec is a unit of distance used to measure huge distances (as in solar system measurements)
1. -2g = 1.75 -4
-g = -2.25/2
g = 1.12
