Answer:
(2 , 0)
(1 , 0)
(4 , 0)
(0, -8)
Step-by-step explanation:
f(x) = x³ -7x² + 14x - 8
The y intercept occurs when x = 0.
This means the first three terms all go to zero an the result is y = -8
As we are given one factor, (x - 4), we know that one zero will occur when this factor is zero
x - 4 = 0
x = 4
taking out the x - 4 term from the quadratic
x³ -7x² + 14x - 8 = (x² ± Cx + 2)(x - 4)
we can see that
2x ± 4Cx = 14x
±4C = 12
C = 12/±4 = ±3
also
±Cx² - 4x² = -7x²
±C - 4 = -7
so C = -3
(x² - 3x + 2)
(x - 2)(x - 1)
x = 2
x = 1
Answer:
Step-by-step explanation:
Start by calculating the effective rate of interest:
.09/52= .0017307
(we divide by 52 because there are 52 weeks in a year)
Then just use the annuity formula
I am not sure but i think it is D 12 years but if i were you i would wait for somebody else to answer.
Answer:
18m?
Step-by-step explanation:
Answer: Find the measures of an exterior angle and an interior angle given the number of sides of each regular polygon. Round to the nearest tenth, if necessary. 24 b 15, 345 24, 156 7.5, 172.5 15, 165
Step-by-step explanation: sum, S, of the measure of the interior angles of a polygon with n sides is: ... The sum of the interior angles of a 24 -gon is 3960. ... angles of a polygon is (n−2)⋅180 , where n is the number of sides. ... Each exterior angle measures 36024=15 . ... The sum of the 24 interior angles is then 24⋅165=3960 .
