of means times so you multiply the fractions
1 x 9 = 9
3 x 16 = 48 (we multiplied numerators and denominators)
9/48 = 3/16 (Simplify by dividing a multiple on both the numerator and denominator
Answer:
y(t) = 494 (1.03)^t
y(10) = 663,89
Step-by-step explanation:
An increase in population by 3% each year means that at the end of each year, the population is 1.03 times what it was at the start of the year
This increase in population continues for t years
Exponential growth model that represents the population y (in thousands) t years after the beginning of the decade is
y(t) = 494 (1.03)^t
Where,
y = population
t = number of years
Find y when t = 10
y(t) = 494 (1.03)^t
y(10) = 494 (1.03)^10
= 494 ( 1.3439)
= 663.8866
Approximately y(10) = 663.89
This means that after 10 years from when the population was 494,000, it increased to 663,89.
Answer:
b 2 to the second -5
Step-by-step explanation:
Answer:This seems easy! do u want help on how to do the answer or r u just looking for the answer????/
Step-by-step explanation:
Two equations
W*L=1260
3W+48=L
Solve
L=1260/W
3W+48=1260/W
3W^2+48W=1260
3W^2+48W-1260=0
Divide by 3
W^2+16W-420=0
Factor
(W-14) (W+30)
W=14
L=90
