Convert 91007500 to scientific notation

1 answer:

8 0

Scientific notation is a number greater than 0 and less than 10 multiplied by 10 to a power. The expression will be equal to the number given.
91007500
We move the decimal place first so that the number is within our range:
9.1007500
Then we count how many places we moved the decimal. In this case we moved it to the left 7 times, so our exponent of 10 will be 7
Therefore in scientific notation it is 9.1007500 x 10^7
Some teachers prefer to have scientific notation rounded off to the nearest 10th place, so that would be:
9.1 x 10^7

$Question$

Why some absolute value equations can have a extraneous solution?

Answer:

it means that thing inside the absolute value A equals either positive B or negative B.

So either the expression on the other side or the expression on the other side with a negative sign in front of it.

Hope this helps!

what is the value of the the expression x+5/y^2 for x = 2/3 and y= 1/3. A. 17/27 B. 17. C.34. D.51

uysha [10]

Answer:

Step-by-step explanation:

x + 5/y^2

x = 2/3

y = 1/3

2/3 + 5 / (1/3)^2 Expand (1/3)^2

2/3 + 5 / (1/9) Put a 1 underneath the 5

2/3 + 5/1 / (1/9) Invert and multiply the second expression

2/3 + 5/1 * 9 Simplify 5/1

2/3 + 5* 9 Combine

45 2/3

I'm not getting any of these. It's possible I'm misreading the question, but what you've given is the result I got. All I can suggest is that you ask your teacher how this is done.

(f+g) means add the expressions together. combine like terms.
$5 {x}^{2} + 3 {x}^{2} = 8 {x}^{2}$
$- 2x + x = - x$
there is no other constant term so the -4 stays as is.
