<h3>
Answer: Choice B) -471,861</h3>
=====================================================
Explanation:
This is a geometric sequence because each new term is found by multiplying the last term by -4.
The common ratio is r = -4. The first term is a = -9. We want to sum up n = 9 terms.
Use the geometric nth partial sum formula below to plug in the terms mentioned
Answer:
3 question papers
Step-by-step explanation:
If the teacher takes 15 minutes to mark 1 question paper. Then they will probably take 30 minutes to grade 2 question paper. Because 15 minutes+15 minutes=30 minutes. Then if you and another 15 minutes which will be 40 minutes because 15 minutes+15 minutes+15 minutes=40 minutes.
Hence, the teacher will mark 3 question papers in 40 minutes
Answer: 5/12

Answer:
Step-by-step explanation:
Total surface area of cube = a^3
here , a = 11 cm
So surface area of the cube = a^3
= 11^3
=1331 cm^3

Answer:
<u><em>(x+5) is not a factor of f(x)</em></u>
Step-by-step explanation:
Step 1 : we solve the equation x +5 = 0
x + 5 = 0 then x = -5
Step 2: we plug in -5 into f(x)
If we get zero then x+5 is a factor of f(x)
If we get a number other than zero then x+5 is not a factor of f(x)
Calculation:
f(-5) = (-5)³ − 4(-5)² + 3(-5) + 7 = - 233
Since we got -233 and not 0
Therefore ,(x+5) is not a factor of f(x)
