Answer:
900
Step-by-step explanation:
Answer:
(a) A = 700×1.015^t
(b) 36.2 years
Step-by-step explanation:
(a) Each year, the account value is multiplied by (1 + 1.5%) = 1.015. Repeated multiplication is signified using an exponent. In t years, when the account has been multiplied by 1.015 t times, the account value will be ...
A = $700×1.015^t
__
(b) You want to find t when A=$1200. Logarithms are involved.
1200 = 700×1.015^t . . . . use 1200 for A
1200/700 = 1.015^t . . . . . divide by 700
log(12/7) = t×log(1.015) . . . . . take logarithms
log(12/7)/log(1.015) = t ≈ 36.2 . . . . divide by the coefficient of t
It will take about 36.2 years for the account balance to reach $1200.
Answer:
no
Step-by-step explanation:
because the sum of the angles of a triangle should = 180, and adding these numbers together give a greater result of 220 degrees
Answer:
-18, 30
Step-by-step explanation:
8 × -2 = -16
-16 - 2 = -18
8×4=32
32-2=30
hope this helps! :)
the original cost was $111.60.
