Step-by-step explanation:
$79.56- $62.51= $17.05.
The stock increased $17.05 in one year~
First, solve the exponent part because it has a higher precedence than multiplication. And we have a negative exponent. Which means we takes the reciprocal of 4 then take to the power of 4.
4^-4 = 1/4^4 = 1/256
Now do the multiplication part.
16 * 1/256 = 1/16
AE = 6
This is because ABE is a right triangle with the right angle being angle BAE. We know that AB = 8 and EB = 10, so we can use the Pythagorean Thoerem to find AE.
D. 44
4.5•2=9
9•3.14=28.26
28.28 rounds down to 28cm
11.5•2=23
23•3.14=72.22
72.22 rounds down to 72cm
72-28=44
