Answer:
to help, i will demonstrate the first problem. This is a right triangle. We know this because it is a 45-45-90 triangle.
Because of this we know that the sides are 2 and 2 (they must be equal).
Now we need the hypotenuse- the side across from the right angle (in other words, the diagonal line).
To do this we take 2 times the square root of two. This makes it 2.82.
I believe the correct answer is that the temperature will be 12 degrees F at 9 A.M. I hope this helps!
Answer:7m^5 - 3m^3 + 9
Step-by-step explanation: You’d have to remove the brackets, but remember that the second has to have everything multiplied by -1, because there’s a minus sign in front of the second bracket. Then you’d group like terms, then add or subtract. Here’s the step by step
6m^5 + 3 - m^3 - 4m + m^5 - 2m^3 + 4m + 6
2. 6m^5 + m^5 - 2m^3 - m^3 + 4m - 4m + 6 + 3
Subtract or add what’s needed, which would be figures with the same variable and coefficient.
3. 7m^5 - 3m^3 + 9
After this, there’s nothing you can add, since the remaining figures don’t have the same variable.
Hope it’s clear and this wasn’t that long
There are no numbers for this, thus you will have to use the quadratic formula.
I = PRT
P = 8000
T = 4
R = 12%...turn to decimal...0.12
now we sub
I = (8000)(0.12)(4)
I = 3840 <==
