Mathematics
1 answer:
irinina [24]3 years ago
4 0

<u><em>1/1024 is the correct answer.</em></u> First you had to apply exponent rule, and it gave us, \frac{1}{(2^5)^2}, or 2^5^*^2. Then you can also refine, and it gave us, 2^10, or \frac{1}{2^10}. And it gave us the answer is 2^1^0=2*2*2*2*2*2*2*2*2*2=1024, or 1/1024 is the correct answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

Write a division problem whose quotient has its first digit in the hundreds place
Margaret [11]
Quotient is another name for the answer to a division problem

the hundreds place is the 3rd number before the decimal, 9999999.0
                                                                                           ^this one

so you need to find a division problem that equals something between 100 and 999

1000 divided by 10 is a good one, the answer to that problem is 100, and 100 has its first digit in the hundreds place.

Fully Factor 3x^2 – 16x + 20
ryzh [129]

Answer:

C. (3x2 - 10) (x - 2)

Step-by-step explanation:

3x^2 - 16x +20

Step 1: Sum = - 16x

Product = 60x^2

Step 2: Find 2 numbers that their sum is -16 and their product is 60. If you do that correctly, then you will get two numbers: 10 and -6

Step 3: Replace -16x with the two numbers found in step 2, then you will have; 3x^2 - 6x - 10x + 20

Step 4: Factorise the equation in step 3, like so;

(3x^2 - 6x)(- 10x + 20)

3x(x - 2) -10(x - 2)

(3x - 10)(x - 2)

To check if the answer is correct, expand the bracket: (3x - 10)(x - 2)

If the bracket is opened properly, you will get 3x^2 - 16x + 20
