Answer:
A. 85°
Step-by-step explanation:
By interior angle sum theorem of a triangle.
x = 180° - ( 40° + 55°)
x = 180° - 95°
x = 85°
Y=mx+b
7=6(3)+b
7-18=b
b=-11
y=6x-11 (i guess that is the answer)
Answer: 0.15
Step-by-step explanation:
Multiply 0.03 by 5.
So for this you will be using an exponential equation, which is with a=initial value, b=growth/decay, y = total balance, and x = # of years
In this case, a = 500, and since with this problem the initial value is growing, you will add 100% to 6% to get 106%, or 1.06. The equation will be formed as such:
With this problem, just plug in 15 into x and solve for y:
In short, after 15 years Tom will have $1198.28 in his account.
