solve the quadratic equation by completing the square x^2+8x+6=0 first choose the appropriate form and fill in the blanks with the correct numbers then solve the equation
By completing squares we will see that the solutions of the quadratic equations is:
x = -4 ± √10
How to solve the quadratic equation?Here we want to solve the quadratic equation:
x^2 + 8x + 6 = 0
Remember the perfect square trinomial:
(a + b)^2 = a^2 + 2ab + b^2
We can rewrite the quadratic equation as:
x^2 + 2*4x + 6 = 0
To complete squares we need to add 4^2 = 16 in both sides, then we will get:
x^2 + 2*4x + 16 + 6 = 16
(x + 4)^2 + 6 = 16
(x + 4)^2 = 16 - 6
(x + 4)^2 = 10
x = -4 ± √10

Greg purchased a baseball bat at a 20% discount. The original cost of the bat was $95. How much will Greg pay for the bat if there is a 6% sales tax?
Answer:
$80.56
Step-by-step explanation:
First determine the cost of the bat after the discount.
20% of 95 = .20x 95 = 19
95-19= $76
Next, you will calculate the additional cost of sales tax.
Sales tax rate = Sales tax percent / 100 (6/100) = .06
Sales tax = List price x Sales tax rate (76 x .06) = 4.56
Total tax equals $4.56
76+4.56= $80.56

What is random sample?A simple random sample is a subset of people selected at random from a larger group of people, all with the same probability, in statistics. This procedure involves choosing a sample at random. A simple random sample is a population subset that has been chosen at random. This sampling technique minimizes the possibility of selection bias by giving every member of the population an exact equal probability of being chosen. The use of random sampling assures that the results of your study should be close to those that would have been obtained from measurements of the complete population (Shadish et al., 2002). The most basic random sample gives every unit in the population an equal probability of being chosen.The mean monthly family income for a sizable population will be calculated using a researcher's random sample of n = 500 families.

3. Ato Liku purchases a house for Br. 250, 000. He makes a 20% down payment, with a balance amortized by a 30 year mortgage at an annual interest rate of 12% compounded monthly. a) Determine the amount of the monthly mortgage payment. b) What is the total amount of interest Ato Liku will pay over the life of the mortgage? c) Determine the amount of the mortgage Ato Liku will have paid after 10 years?
Answer:
a) To determine the monthly mortgage payment, we first need to calculate the amount of the loan, which is equal to the purchase price of the house minus the down payment. In this case, the loan amount is 250,000 * 0.8 = 200,000. Next, we need to calculate the monthly interest rate, which is equal to the annual interest rate divided by 12. In this case, the monthly interest rate is 0.12/12 = 0.01. Using the formula for the monthly mortgage payment (P = L[i(1+i)^n]/[(1+i)^n-1]), where P is the monthly payment, L is the loan amount, i is the monthly interest rate, and n is the number of payments (in this case, 30 years * 12 = 360), we can calculate the monthly payment as:
P = 200,000[0.01(1+0.01)^360]/[(1+0.01)^360-1] = 1326.91
b) To calculate the total amount of interest Ato Liku will pay over the life of the mortgage, we can subtract the original loan amount from the total amount of payments made over the life of the mortgage. In this case, that would be 360 * 1326.91 - 200,000 = 480,596.
c) To determine the amount of the mortgage Ato Liku will have paid after 10 years, we can multiply the monthly mortgage payment by the number of payments made in 10 years (10 years * 12 = 120). In this case, that would be 120 * 1326.91 = 159,223.20.
