Answer:
Step-by-step explanation:
So we have a rectangle and a triangle.
The height you can find for the triangle is 12ft
And for the rectangle it is 6ft
Formula for area on triangle is 1/2(b*h)
Or for the given picture
A = .5(15 * 12)
= 90ft^2 ( The area of the triangle)
Next for the rectangle
C = length * width
= (3 * 6)
= 18ft^2 (area of rectangle)
Boom that is it no Pi needed
To find the slide we can us the pythagorical theorem that say:
Where l1 and l2 iare the leg of the triangle so in our problem will be:
So the slide is 35 ft
Answer:
Intrest Income= 434.87, Account Balance= 4434.87
Step-by-step explanation:
To solve this problem, we can use the exponential growth formula.
To find the decimal for 3.5%, divide it by 100. 3.5/100=0.035
The formula is F(T)= A(1+R)^T
A= Initial Amount
R= Regrowth rate
T= Time period
Now insert everything,
F(T)= 4000(1+0.035)^3
Now solve the problem,
4000(1.035)^3 (First do the exponent, then multiple)
1.035^3= approx 1.108717875 or 1.11
4000*1.108717875=
Our account balance is 4434.87, after 3 years.
4434.87-4000 will give us the interest income after three years,
The interest income is 434.87.
One and six tenths. i hope this helped you!!
