I'm assuming the given function is f(x) = 15x^2 + 10x.
If so, then,
f(x) = 15x^2 + 10x
f(x) = 15*(x)^2 + 10*(x)
f(-1) = 15*(-1)^2 + 10*(-1) ... note how x is replaced with -1
f(-1) = 15*(1) + 10*(-1)
f(-1) = 15 - 10
f(-1) = 5
Therefore the answer is 5
2^3 = 2 x 2 x 2 = 8
your answer is 8
hope this helps
f(3) is equal to -101.
<u>Step-by-step explanation</u>:
- The sequence is followed by f(0)=4
- The given expression is f(n+1)= -3f(n)+1
Put n=0,
f(0+1)= -3f(0)+1
f(1)= -3(4)+1
f(1)= -12+1 = -11
Put n=1,
f(1+1)= -3f(1)+1
f(2)= -3(-11)+1
f(2)= 33+1 = 34
Put n=2,
f(2+1)= -3f(2)+1
f(3)= -3(34)+1
f(3)= -102+1
f(3)= -101
Answer:
Step-by-step explanation:
If 75 percent is 180 pages, we need to find the amount of pages the remaining 25 percent of the book has and add that to 180 pages because 75+25 = 100. 75/3 is equal to 25.
75:180 =
25:60.
By dividing the ratio, we found out that if Logan read 25 percent of his book, he would have read 60 pages.
180 + 60 = 240.
The total number of pages is 240
Distribute
5c + 4 = 2c - 10
Subtract 2c from each side
3c + 4 = -10
Subtract 4 from each side
3c = -14
Divide each side by 3
c = -4 2/3
The answer is #1
