Answer:
I think it's the 3rd one
Step-by-step explanation:
because it makes sense
You can take any 2 points from the table and calculate the slope, as follows:
-2-(-4) 2
m = slope = ---------- = ------ = -1/5
-5 - 5 -10
The slope-intercept form is y = mx + b. You already know m (which is -1/5), and have several points from which to choose to obtain x and y. Let's use the given point (-2, -1).
Then -1 = (-1/5)(-2) + b, or -1 = 2/5 + b. Solve for b.
-5 = 2 + 5b, so 5b = -7, and b = -7/5.
The desired equation is y = (-1/5)x - 7/5.
Answer:
9000watts
Step-by-step explanation:
m=50kg
g=10
h=6
t=3
formula=work done×time
work done=m×g×h
Answer=m×g×h×t
