Answer:

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

For example, 750,000,000 can be written in scientific notation as 7.5 ✕ 10^8.

Step-by-step explanation:

Move the period to the right it is positive

Move the Period to the left it is negative | 55 can be written in scientific notation as 5.5 x 10^-1

How do you graph 8x -7 = 16

lys-0071 [83]

Get in standard form first. You need it to be y=mx+b
So you’d have y=8x-23
You’d plot (0,23) first and then rise 8 from that point and run over 1

Which statements are true about the unknown side length in this right triangle? Check all that apply.

belka [17]

Answer:

The true statements are:

1) The equation a squared + (√13) squared = 6 squared can be used to find the unknown length.

2) The length of the unknown leg is √23 meters.

=================================================

Step-by-step explanation:

The hypotenuse of the right triangle = 6

And the length of one leg is √13

using Pythagorean equation: c² = a² + b²

where c is the hypotenuse and a , b are the length of the two legs

So, the third side = $\sqrt{6^2-(\sqrt{13} )^2} =\sqrt{36-13} =\sqrt{23}$

So, the true statements are:

1) The equation a squared + (√13) squared = 6 squared can be used to find the unknown length.

2) The length of the unknown leg is √23 meters.
