Hector's parents started saving money for his college education when Hector was six. If they save $400 per month at a credit union account, paying 2.5% interest compounded daily, how much will Hector have for college expenses 12 years later?
Answer:
$539.94
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r/m)^mn
FV = Future value
P = Present value = $400
R = interest rate = 2.5/ 365
N = number of years = 12 x 365
$400 x ( 1 + 0.025/365)^4380 = $539.94
If using the method of completing the square to solve the quadratic equation x^2-13x+5=0, which number would have to be added to "complete the square"?
Answer:
(13/2)^2
Step-by-step explanation:
Hope this will help
Solving the quadratic equation by completing the square method (13/2)² is added.
What is a quadratic equation?A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
One method for locating the roots of a quadratic equation is to complete the square method. We must convert the given equation into a perfect square using this method. The quadratic formula can also be used to calculate the roots of a quadratic equation.
The given quadratic equation is x²-13x+5=0. Solve the equation by completing the square method as
x² - 13x + 5 = 0
( x - 13 / 2 )² = -5 + (13/2)²
Here in the equation (13/2)² is added to solve it by completing the square method.

Answer:
m=5?
Step-by-step explanation:
Answer:
Step-by-step explanation:
y=mx+b where m is the slope we can solve for y to see the slope.
