The curtains will be 152 cm or 1.52 m.
There are 100 cm in a meter. Therefore, 1.6 meters is equal to 160 cm. If we subtract 8 from 160, we have 152 cm. We can also write it as 1.52 m.
Answer:
The constant in the polynomial is 9. A constant number is a number that does not change during the equation. This equation is 4x² + 9. Since you are just adding 9 the number of 9 does not change. If you were multiplying 9 it would not be a constant anymore because it does not stay the same throughout the equation.
Hope This Helps :)
C = 3.5t....when t = 15
c = 3.5(15)
c = 52.50 <==
First, we need to solve for the common ratio from the data given by using the equation.
a(n) = a(1) r^(n-1)
15 = -3 r^(2-1)
-5 = r
r = -5
Then, we can find the sum by the expression:
S(n) = a(1) ( 1 - r^n) / 1-r
S(8) = -3 (1 + 5^8) / 1+5
S(8) = -195313
