Answer:
(x - 
)² + 
Step-by-step explanation:
x² - 5x + 8
Using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 5x
x² + 2(- )x + 
- + 8
= (x - )² - + 
= (x - )² +
Answer:
Step-by-step explanation:
Let the larger number is a and the smaller number is b.
According to the question,
a² + b² = 100 .... (1)
And
a² = a (4b + 8a)
a = 4b + 8a
b = -7a/4 ..... (2)
Put in equation (1)
65a² = 100 x 16
Put in equation (2)
65,000 really easy once you know
Answer:
$289,169.84 (to the nearest cent)
Step-by-step explanation:
Compound interest is based on the principal amount and the interest that accumulates on it in every period.
Compound Interest = P (1 + r)^n
where P = principal amount, r = annual interest rate (as a decimal), n = term, in years
So for this problem:
P = 185000
r = 1.4 ÷ 100 = 0.015
n = 30
Therefore,
Compound Interest = P (1 + r)^n
= 185000 x (1 + 0.015)^30
= 185000 x (1.015)^30
= 289169.8408...
= $289,169.84 (to the nearest cent)
