Answer: D. (4,3)
The x coordinates of A and B are 9 and -1 in that order. Add them up to get 9+(-1) = 9-1 = 8. Then divide by two to end up with 8/2 = 4. The midpoint has an x coordinate of 4.
Repeat for the y coordinates. Add them up: 8+(-2) = 8-2 = 6. Then divide by two: 6/2 = 3. The midpoint has an y coordinate of 3.
Those two coordinates pair up to get (x,y) = (4,3) which is the midpoint of segment AB.
a. The lightbulb uses the energy of 960 W or 9.60 kW.
Step-by-step explanation:
Step 1:
To determine the energy used by the appliances we need to understand the equation
To determine the energy used, we multiply the power of the appliance with the amount of time it has been used for.
Step 2:
The lightbulb has a power of 60 W and is used for a period of 16 hours.
The energy used by the lightbulb 
W = 0.96 kW.
The toaster oven has a power of 1,500 W and is used for 0.75 hours.
The energy used by the toaster oven 
W = 1.125 kW.
I THINK there is a typo. Instead of "for problems each day", i think it's "four problems each day."
Anyway, we need to find how many days it takes Jeremy to complete the paper.
If he completes 8 problems on the first day and 4 on the rest of the days, after the first day he'll have 28 - 8 = 20 more problems.
And since he does 4 every day with 20 problems: 20 / 4 = 5 days.
Answer:
(3 x 10^3) / (12 x 10^6) = 0.00025
Answer:
Step-by-step explanation:
Product means multiply
(10x^4y^2)(3xy3)
Numbers: 10*3 = 30
x: x^4 * x = x^5
y: y^2 * y ^3 = y ^ 5
Answer: 30x^5y^5
Powers don't multiply, they add. How confusing!
