Scientific notation:
8.41 x 10^7
expanded form:
84100000
Parallel lines always have the same slope. If we use the example you gave, y = x - 10, the slope of the line is 1. We just have to find another line with a slope of 1. It doesn't matter what the y-intercept is, the slope just has to be the same. Some examples of parallel lines to y = x-10 are y = x, y = x + 5, or y = x - 5. Hope this helps!
Answer:
it is in the equation
Step-by-step explanation:
Using Pythagorean theorem, we can find that DG is 10.(I don't think I need to explain this)
Now cosD means the adjacent side over the hypotenuse.
The side adjacent to <D is 6 and the hypotenuse is 10 so
cosD=6/10=3/5
Which means the correct answer is choice D.
Hope this helped!
Answer:
Step-by-step explanation:
y=x^2+8x+12
y = (x² +8x +16) -16 +12
y = ( x +4)² - 4....standard vertex form
the vertex is : A(- 4 ; - 4)
