If the apy of a savings account is 4.7% and if the principal in the savings account is 4500 for an entire year, what will be the balance of the savings account after all the interest is paid for the year
a. 4500.00
b. 4521.15
c. 4711.50
d. 4700.00

step-by-step explanation:

its an acute right triangle

step-by-step explanation:

c-   36

taxicab circle radius 9 has 4(9) = 36 points

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
