First you need to find the slope of the line containing those 2 points using the slope formula. Filling in with our info we have

. So the slope is -1.5. Now we need to find out the rest of the info, mainly the y-intercept. The line appears to go through the y axis at (0, 0), but let's make sure. We will use the slope we just found and one of our points to solve for the y-intercept. I picked point (4, -6). Filling in to solve for b we get -6 = (-1.5)(4) + b. Doing the multiplication on the right gives us -6=-6 + b. Add 6 to both sides to get that b = 0. Now let's use that and the slope we found to rewrite the equation in slope-intercept form. y = -1.5x + 0 or y = -1.5x and there you go!
Answer:
C(t) = 6 + .4t
Step-by-step explanation:
Since there is a constant rate of 6 for the first 5 minutes, that would be a value itself. After that, it would always differ by .4 every minute, making this the function.
Answer:
b. d > 6
Step-by-step explanation:
The answer would be Weak negative
Answer: 4.64805 pounds of CO₂ was produced
Step-by-step explanation:
Given that;
wattage = 4694 watt = 4694 /1000 = 4.694 kW
time in use t = 10hrs
CO₂ was produced = ?
Total Energy produced = wattage × time = 4.694 kW × 10hrs = 46.95 kWh
we know that 1 kWh produces 0.99 pounds of CO₂
so
46.95 kWh will produce ⇒ 46.95 kWh × 0.99 = 4.64805 pounds of CO₂
Therefore 4.64805 pounds of CO₂ was produced
