1024=2*2*2*2*2*2*2*2*2*2=2^10 (means 2 times itself 10 times)
the options re
A. 4^5
B. 512^2
C.254^4
D. 5^4
see if any of them can be simplified to 2^10
we know that
so
4^5=(2^2)^5=2^(2*5)=2^10
true
he answer is A. 4^5
4^5
Why?
Because,
4^5 = 4 × 4 × 4 × 4 × 4 = 1024
4^5 = 1024
1024 written as a power of a number is 4^5.

7-(-12)=19
Answer:
x = -12
Step-by-step explanation:
To solve an equation, you want to "undo" what has been done to the variable. Here, it has been multiplied by -1 and that result added to 7. In general, you want to "undo" these operations in reverse order.
First, you need to subtract 7 to undo the addition of 7. Of course, anything you do to one side of the equation is also done to the other side:
7 -x -7 = 19 -7
-x = 12 . . . . . . . . simplify
Now, you want to undo the multiplication by -1. Multiplication (or division) by -1 will take care of that:
(-1)(-x) = (-1)(12)
x = -12 . . . . . . . . simplify
The solution is x = -12.

Answer:
(0,1) and (-2,4)
Step-by-step explanation:
Reflection over y axis means that the x axis coordinate will be negative as it will now have shifted to the other side of the axis. Since (0,1) is on the y axis it will remain in it's position not changing. (2,4) will change to (-2,4) as it is now at the other side (negative-x side) of the y axis. I hope I helped

To solve a kind of question like this and to have a better understanding while solving it. It is pertinent to list out the parameters given:
List of Items bought by Nicole:
- Volleyball = $9.75
- Net = $29.99
- Knee pads = $15.00
If Nicole gave her mother the money $40 for babysitting, and:
Her mother paid back $5.26 out of it.
Then, the total amount of money Nicole's mother owed Nicole can be calculated by adding the items Nicole bought with the amount her mother paid her back, then we will subtract the total amount from the money Nicole gave her mother for babysitting.
Mathematically, we have:
= $(9.75 + 29.99 + 15+ 5.26) - $(40)
= $60 - $40
= $20
Therefore, we can conclude that the amount of Money Nicole's mother owed Nicole for babysitting is $20
Learn more about arithmetic operations here:
To figure this out just add:
9.75 + 29.99 + 15 + 5.26 = $60 Since this is $20 more than Nicole gave her mom that means she made $20 baby sitting. There's your answer!
