Hello from MrBillDoesMath!
Answer:
f(-1) = 2
f(1) = 6
f(2) = 11
Discussion:
Let f(x) = 2x^3 - 3x^2 + 7. Then
f(-1) = 2 (-1)^3 - 3 (-1)^2 + 7 = -2 -3 + 7 = -5 + 7 = 2
f(1) = 2(1)^3 - 3(1)^2 + 7 = 2 -3 + 7 = -1 +7 = 6
f(2) = 2(2)^3 - 3(2)^2 + 7 = 2*8 - 3*4 + 7 = 16-12+7 = 11
Thank you,
MrB
Hello :
the sum is arithmetic secquence of common -diff is :
(-7)-(-5) =(-5)-(-3) = (-3)-(-1) =-2 = d
the first term is : a1 = -1
<span>the formula of the sum : S= (n/2)(a1 +an)
n is number of term an = a1+(n-1)d</span>
A more simplified way to show this is 3/10

Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Price of home = $220,000
Down payment = 20%
3 points at closing
30 years fixed rate mortgage at 7%
A.)The down payment :
20% of price
0.2 × $220,000 = $44,000
B.) Amount of the Mortgage :
Price - down payment
$220,000 - $44,000 = $176,000
C.) Amount to be paid for the 3 point of closing :
3% of mortgage amount
0.03 * $176,000 = $5,280
D.) monthly payment :
(mortgage amount(1 + rate)) / 30* 12
176000(1 + 0.07)
($176,000 + $12320) / 360
$523
E.) Total cost of interest :
0.07 * 176000 = $12,320
