Answer:
8x10^-7
Step-by-step explanation:
First one you have correct however the second one you were close lets figure it out:
0.0000008
In order to move the decimal in front of the eight we have to "jump" 7 times to the right. Furthermore since we have to move the decimal to the right our exponent will be negative. That means that we have:

Answer:
x = 13.9
Step-by-step explanation:
With respect to the angle shown, we have the hypotenuse (the side opposite the 90 degree angle) and we have the adjacent side (which is the side labeled x). thus we can use the ratio "cosine" to solve this.
<em>The ratio of cosine is defined as:</em>
Where adjacent and hypotenuse are the respective sides and is the angle
<em>Thus, we can now write:</em>
The first answer choice is right, x = 13.9
Answer:
B 4m
Step-by-step explanation:
If the height is 5 the base has to be four because of the equation base x height / 2
5*4=20
20/2=10
Answer:
The coefficient of x² in the expression is 2
x/3(6x-1/2) = 6x²/3 - x/6
= 2x² - x/6
