Answer:
0.000000049.
Step-by-step explanation:
This will have 7 zeros after the decimal point followed by 49:
4.9 × 10^–8 = 0.000000049.
If we imagine the decimal point making jumps to the right over the digits it takes 8 jumps till it gets to 4.9. that's where the -8 comes in.
Answer:
y=2x
Step-by-step explanation:
2 up, 1 over. put rise over run so that concludes the 2x.
The line starts at 0 so there is no y-intercept
Answer:
Step-by-step explanation:
point-slope equation looks like y-y1 = m(x-x1)
plug in the given point for x and y.... and the slope for m
y-9 = 3/2(x-6)
y-9 = 3/2x - 9
y = 3/2x
Answer:
≈ 82 feet
Step-by-step explanation:
Since the triangle is right use Pythagoras' identity to calculate distance (d)
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
Here the hypotenuse is the distance (d) between the 2 poles, hence
d² = 80² + 45² = 6400 + 2025 = 8425 ( take the square root of both sides )
d = 
≈ 82 feet ( to the nearest foot )
A. 36 is your answer
2 x 3 = 6 x 6 = 36
coefficient is the number in front of the variable. In the case of 36Q, it is 36
hope this helps
