Answer:6x2=12-10=2 and 4×+3=12
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.
rate of change as in the gradient??
if yes then the formula would be rise over run, so y over x, therefore 1/3
Answer:
-x² + x + 6
Step-by-step explanation:
Hey there!
To solve this, you have to use foil...
( 3 - x ) ( x + 2 )
3 ( x + 2 ) = 3x + 6
-x ( x + 2 ) = -x² - 2x
3x + 6 - 2x - x²
-x² + x + 6
Hope this helps :)
