Answer:
Your grade point average would be 2.75(B- or C+)
Step-by-step explanation:
The thousands place value is the fourth digit (number) to the left of the decimal point. If the decimal point is not present, it goes to the right of the digit at the end of the number. So 4 over from that is the starting number, 4. So there are 4 thousands in the thousands place
Answer:
1 9
2 11
3 13
4 15.
Step-by-step explanation:
When x = 1 y = 2(1) + 7 = 9.
x = 2, y = 2(2)+7 = 11
x = 3, y = 2(3) + 7 = 13
x = 4, y = 2(4) + 7 = 15.
Answer:
1256
Step-by-step explanation:
Given the function F(x)=1256(1.24)^x, the initial value occurs at x = 0
Substitute x = 0 into the function;
F(0)=1256(1.24)^0
f(0) = 1256(1) (any value raise to sero is 1)
f(0) = 1256
hence the initial value is 1256
