A) A=500(1+0.015)^t
b)800=500(1.015)^t
800/500=1.015^t
t=log(800/500)/log(1.015)
t=31.6 years
Answer:
w = -27
Step-by-step explanation:
w/3 = -9
3(w/3) = 3(-9) <em>isolate</em><em> </em><em>w</em><em> </em>
w = -27
Answer:
Step-by-step explanation:
Formula
AB = sqrt( (x2 - x1)^2 + (y2-y1)^2 )
Givens
x2 = 6
x1 = - 4
y2 = -2
y1 = 8
Solution
AB = sqrt( (6 - - 4)^2 + (-2 - 8)^2 )
AB = sqrt(10^2 + (-10)^2 )
AB = sqrt(100 + 100)
AB = sqrt(200)
AB = 10*sqrt(2)
AB = 10* 1.4142
AB = 14.41
(x+4)−(x−1) simplified = 5
