Answer:
-26
Step-by-step explanation:
9+33-6
calculate the sum of the positive numbers
42-6
subtract the numbers
36 divided by 6-32
6-32
-26
I think the answer is 3.5 cause when you divide it 7 go inside and 7 there's nothing you can multiply to get 7
Answer:
Ok, first in our series we can see two numbers in the Sigma, one bellow 0, and other above, 4.
This means that the value of k will go from 0 to 4, then all the numbers in the sum are:
(-1/2)^0 + (-1/2)^1 + (-1/2)^2 + (-1/2)^3 + (-1/2)^4
So we have 5 terms in our series.
b) to see the sign in each term, we must solve the powers, remember that:
(-1)^n is -1 if n is odd, and is equal to 1 if n is even, so we have:
(-1/2)^0 + (-1/2)^1 + (-1/2)^2 + (-1/2)^3 + (-1/2)^4
= 1 -1/2 + 1/4 - 1/8 + 1/16.
So the sign in each term of the series alternates.
Answer: 300*0.73^x
Step-by-step explanation:
300 is the initial value and every time x goes up by 1, the value get multiplied by 0.73
when x=3
then the value would be 300*0.73*0.73*0.73 or 300*0.73^3
then for x amount of times the equation would be 300*(0.73 x times ) or 300*0.73^x
Answer:
Read my explanation
Step-by-step explanation:
Since they both end with a 0, you can just cancel it out. So you'd have 484/9.
The answer to that is 53.7777777777...
So the decimal would come before the 3 and after the 7.
I hope this helped and have a good rest of your day!
