Since the triangle is equilateral, QR = RS = QS.
a. MS = (1/2)74
MS = 37
b. Half of the equilateral triangle makes a right triangle. Use Pythagorean Theorem to find QM.
a^2 + b^2 = c^2
37^2 + b^2 = 74^2
1369 + b^2 = 5476
subtract 1369 from both sides
b^2 = 4107
take the square root if both sides
b = 64.1
QM = 64.1
y-intercept for x = 0.
Substitute x = 0 to the equation of the function:
Oder of operations is this;
Answer:
$911.02
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 1.25%/100 = 0.0125 per year,
then, solving our equation
I = 845 × 0.0125 × 6.25 = 66.015625
I = $ 66.02
The simple interest accumulated
on a principal of $ 845.00
at a rate of 1.25% per year
for 6.25 years is $ 66.02.
