if $95 is put in an account that gets 6% and I add $18 per year how much will I have at the end of 11 years?
VLD [36.1K]
First, you need to get the 6% of $95 which would be: $5.70. Then you need to multiply $5.70 to 11 to know how much of the 6% of $95 will be added at the end of 11 years. It will leave you with $62.70. Since you're adding $18 per year, you need to multiply it by 11 which would be $198. Now that you calculated all the money you will be having at the end of 11 years, you just need to add them all up. Since you have already $95 + $62.70 + $198 = $355.70. The total money you will be having is $355.70.

. A population is currently 6,000 and has been increasing by 1.2% each day. Write an exponential model for the population.
larisa86 [58]

Answer: A=6000(1.012)^t

Step-by-step explanation:

General exponential function:

A=P(1+r)^t

, where P= current  population

r= rate of growth

t= time period

A= population after t years

As per given , we have P=6,000

r= 1.2% = 0.012

Then, the required exponential function:  A=6000(1+0.012)^t

or A=6000(1.012)^t

Please someone help me .I need help. Focus on number 4
eimsori [14]

Answer:

No

Step-by-step explanation:

To determine if the point (- 3, 5) is a solution to both equations.

Substitute the x and y values into the left side of both equations and if equal to the right sides then the point is a solution.

x - 3y = - 3 - 3(5) = - 3 - 15 = - 18 ← True

- 2x + y = - 2(- 3) + 5 =  6 + 5 = 11 ← False

Thus (- 3, 5) is not a solution to the system of equations.
