Answer:
Step-by-step explanation:
Since we are talking about compounded annual interest, we can use the Exponential Growth Formula to calculate the answer for this question.
Where:
- y is the total amount after a given time
- a is the initial amount
- r is the interest rate in decimal form
- t is the amount of time
First we need to calculate the total after 2 years with a 9% interest.
So after 2 years there will be £1,188.10 in the account. Now we can add £3000 to that and use the new value as the initial amount, and calculate the new total in 5 years.
So now we can subtract the £4000 purchase from the amount currently in the account, and calculate one more year of interest with the new initial amount.
So at the end you would have £2,662.86 in the account one year after the purchase.
B.) (15 + 2)x because they both are getting multiplied by the value of x making it 17x.
Answer:
I think it iss 6$
Step-by-step explanation:
what's 15% of 66 half of that number is 6 so i think its 6$ if its not I'm sorry
176 in The area of the first square is 44 and you want to find the second square you will have to do 44*4=176
Answer:
y= -1x-6
Step-by-step explanation:
The equation would be y=mx+b
M= slope, and B=y-intercept
If you look at a graph and use the slope to get to the Y-intercept you'll see that it is -6, and so you would just plug that into the equation along with the slope :)
