Answer:
slope= - 5/4
Step-by-step explanation:
Answer:
R = 5% per year
Step-by-step explanation:
Solving for rate r as a decimal
r = n[(A/P)^1/nt - 1]
r = 4 × [(4,835.71/3,092.00)^1/(4)(9) - 1]
r = 0.05
Then convert r to R as a percentage
R = r * 100
R = 0.05 * 100
R = 5%/year
Summary:
The interest rate required to get a total amount of $4,835.71 from compound interest on a principal of $3,092.00 compounded 4 times per year over 9 years is 5% per year.
Sine (theta) = 5 / hypotenuse
We do not know the hypotenuse length, so let's use the tangent function.
tan (theta) = 5/7
arc tan (5/7) = 35.538 Degrees
The answer is a. 1/7
The length of QR is 3 sqrt(2) which means half of that is where the median intersects. Since the triangle formed is a right triangle with legs that are equal. The vertex angles are 45°, we can get the coordinates of the point of intersection which is (4.5,3.5).
So,
m (slope) = (3.5-3)/(4.5-1) = 1/7
