Answer:
Simplifed (X-5)(x^2+4x-2) = x^3 − x^2 − 22x + 10
Step-by-step explanation:
Expand ( x − 5 ) ( x^2 + 4x − 2 ) by multiplying each term in the first expression by each term in the second expression.
x ⋅ x^2 + x (4x) + x ⋅ −2 −5x^2 − 5 (4x) −5 ⋅ −2
Simplify terms.
x^3 − x^2 − 22x + 10
I hope this helps.
Since the roots are 2,3i, and -3i, you can write it as
(x-2)(x-3i)(x+3i)=(x-2)(x^2+9)=x^3-2x^2+9x-18.
Answer:
x=0
Step-by-step explanation:
4 ( 2.5) ^x = 4
Divide each side by 4
4/4 ( 2.5) ^x = 4/4
( 2.5) ^x = 1
Take the log of each side
log ( 2.5) ^x = log (1)
x log ( 2.5) = log 1
x log (2.5) = 0
Divide each side by log (2.5)
x = 0

Answer!!!!!!!!!!!!!!!!!!!
Answer:
19.38 Months, so 1.6 years
Step-by-step explanation:
6.5% compounded monthly is $325 a month (5,300*.065) so if you subtract 11,300-5,000 you get $6,300. You divide that by 325 and you get 19.38 (months) divide that by 12 months and you get 1.6 (years)
