Answer:
g(4) = -5, h(8)= 8, f(-2)= -7, g(-2)= 7
Step-by-step explanation:
It's pretty simple. The number in the parenthesis is the value of x.
Therefore, you look at the table, find the required function and the value of x that is given.
The number that is in the answers is the value of y.
Answer:
60500
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
= [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 4 and d = 7 - 4 = 3, thus
= [ (2 × 4) + (199 × 3) ]
= 100(8 + 597)
= 100 × 605
= 60500
Area= 190
height= 2(width) - 1
area= length times width
190= (2(width) -1) x width
190 = 2w^2-w
w^2-w-190 = 0
use quadratic fomula, you'll get w= 10
so height will be 2(10)-1 = 19
Answer:
Final answer is $9000.
Step-by-step explanation:
Given that Alice took out a $15,000 loan for college. She is borrowing money from two banks. Bank A charges an interest rate of 6%, and Bank B charges an interest rate of 7%. After one year, Alice owes $960 in interest.
Now we need to find out about how much money did she borrow from Bank A.
So let's assume that money borrowed from bank A = x
then money borrowed from bank B = 15000-x
Interest from bank A = 6% of x = 0.06x
Interest from bank B = 7% of (15000-x) = 0.07(15000-x)
Given total interest is $960. So we can write equation:
0.06x+0.07(15000-x)=960
0.06x+1050-0.07x=960
1050-0.01x=960
-0.01x=960-1050
-0.01x=-90
x=9000
Hence final answer is $9000.
