Answer:
- 18
Step-by-step explanation:
note that | 9 | = 9 , thus
- 2 | 9 | = - 2 × 9 = - 18
Scientific notation is a way of writing numbers in a form of a decimal multiplied by an exponent of 10.
For these, the exponent will be negative, since they're teeny tiny decimals, and we'll have to move the decimal point back to the right.
0.00000012 will become
This is because the decimal point is moved seven places to the right of where it originally was.
0.000005008 will become

Again, this is because the decimal point is moved seven places to the right of where it originally was.
So, your scientific notations are

and
Answer:
A= 30
Step-by-step explanation:
This requires several steps.
First, you need to find the 2 other missing angles.
One can be found easily by substracting 130 from 180
so 180-130 = 50
The other angle is the same as 8x+4
Now set up your equation
180=3x-6 + 8x+4 +50
180 = 3x + 8x -6 + 4 +50
180+6-4-50 = 11x
132 = 11x
132/11 = x
12 = x
Now plug in 12 for x in your angle A
A=3x-6
A=3 * 12 - 6
A=36 - 6
A= 30
The slope of the line is 2
Answer:
(1/2 ,3) or (0.5, 3) is the same
Step-by-step explanation:
The midpoint between (3,5) and (-2,1) would be:
Apply the formula:
x1+x2 / 2 , y1 + y2 / 2
= 3 + (-2) / 2, 5 + 1 /2
= 1/2, 6/2
= 1/2 ,3 or 0.5, 3 is the same
Hope this helped :3
