I know my math and your answer is going to be A.
Hello :
<span>the general term equation, an, for the arithmetic sequence is :
An = A1+d(n-1)
A1 : the first term and : d the common diference
in this exercice :
A1 = 9
d =(-3)-(1) =(1)-(5) =(5) -(9) = -4
An = 9-4(n-1)
An = -4n +13</span>
Answer:
C. 2.8 * 10^-5
Step-by-step explanation:
Ok so its been a while since I've done these but pretty sure c is the answer. (Double check to make sure I'm correct)
1. The value of (cd)(x) is equal to the product of c(x) and d(x) which is equal to,
5(x + 3) / (x - 2)
The function can take all real numbers except 2 because that would make the denominator 0.
2. To answer, substitute first 5 to the given functions,
f(x) = 7 + 4x = 7 + 4(5) = 27
g(x) = 1/2x = 1 / (2)(5) = 1/10
Dividing 27 by 1/10 is 270.
Answer:
divide by 8
2.25 cubic units
Step-by-step explanation:
3 x 6 half cubes = 18 half cubes
one cubic unit =1/8 cubic units
18/8=2.25 cubic units
