Could i have branliest please and a heart
we know that
The simple interest formula is equal to
![A=P(1+rt)](https://tex.z-dn.net/?f=A%3DP%281%2Brt%29)
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
![t=5\ years\\ P=\$8,500\\ A=\$10,093.75\\r=?](https://tex.z-dn.net/?f=t%3D5%5C%20years%5C%5C%20P%3D%5C%248%2C500%5C%5C%20A%3D%5C%2410%2C093.75%5C%5Cr%3D%3F)
substitute in the formula above
![10,093.75=8,500*(1+r*5)](https://tex.z-dn.net/?f=10%2C093.75%3D8%2C500%2A%281%2Br%2A5%29)
solve for r
![5*r=(10,093.75/8,500)-1](https://tex.z-dn.net/?f=5%2Ar%3D%2810%2C093.75%2F8%2C500%29-1)
![r=0.0375](https://tex.z-dn.net/?f=r%3D0.0375)
![r=3.75\%](https://tex.z-dn.net/?f=r%3D3.75%5C%25)
therefore
<u>the answer is</u>
the rate of interest is ![3.75\%](https://tex.z-dn.net/?f=3.75%5C%25)
Answer:
A.
Step-by-step explanation:
1. Write down the coordinates of the two points on the line.
(-4,-3) (-1,2)
2. Use the slope formula to find the slope.
Slope formula: y2-y1/x2-x1
2--3/-1--4
Slope: 5/3
Answer:
A. ( x + 2)²=9
Step-by-step explanation:
2x2 + 8x = 10 equivalent to :
x²+4x =5 ....(divid by2)
(x²+4x+4 ) - 4=5
(x +2)² - 4 = 5
(x +2)² =9...(add 4)
