Answer:
16
Step-by-step explanation:
Solve 5 to the power of x minus 3 to the power of x when x=2.
So, you do 5 to the power of 2 minus 3 to the power of 2, which is 25-9=16
Volume of a sphere=(4/3)πr³ ⇒r=∛(3v/4π)
volume of a sphere=950 in³
Therefore:
r=∛(3*950 in³/4π)=6.09834... in≈6.1 in
answer: radius=6.1 in
Answer:
D
Step-by-step explanation:
w = 6 m
L = 1/2 m
Area = 1/2 * 6
Area = 3 m^2
Are you sure you have the givens correct? If you are hesitant about this answer, ask your instructor how it is done.
Edit
In that case (L = 12) then the area is
Area = 12 * 6
Area = 72
So the answer is D
Sketch a graph so you can find the vertex and determine if the parabola is horizontal or vertical. When i graph (-2,4) and then y=6, I find the middle is (-2,5) so that will be the vertex. The distance to the vertex is -1 so 4p=-4.
My formula is (x-h)^2=4p(y-k), now just plug in numbers. You should end up with (x+2)^2=-4(y-5).
Some instructors want you to write (y-k)=1/(4p)(x-h)^2 which is the same thing, so check to see which one you should be using.
