The correct answer is C)
.
Since it is a geometric sequence, we multiply by a constant, r, each time to find the next term.
g₂ = -8
g₅ = 512
g₂ * r * r * r = g₅
-8(r)(r)(r) = 512
-8r³ = 512
Divide both sides by -8:
-8r³/-8 = 512/-8
r³ = -64
Take the cubed root of both sides:
∛r³ = ∛-64
r = -4
Now we work backward from g₂ to find g₁:
-8/-4 = 2
We have that g₁ = 2 and r = -4. This gives us

Here’s why:
- The average is found by dividing the sum of the values by the number of values.

The numerator would consist of the test grades and the unknown 'g' and the denominator would be the number of tests he taken.
"At least" indicates a greater than or equal to inequality.

Answer:
4a. S = 300c
4b. S = 2400
Step-by-step explanation:
4a. There are 300 seats in a conference room 'c' so to find the amount of seats there are in total you need to times these values so...
S = 300c
4b. substituting 8 into c gets
S = 300x8
S = 2400
hope this helps!
Its C the third one i just had the that question on my test
