Yes, this is a polynomial, but a special form of a polynomial with just one term which is called a monomial .
Answer:
I think is -x + 105/42y
Step-by-step explanation:
2(3/10)x - 5/7y - 4(5/6)y - 2(4/5)x
6/10x - 5/7y - 20/6y - 8/5x
6/10x - 8/5x - 5/7y - 20/6y
6-16/10x - 35+140/42y
-10/10x + 105/42y
-x + 105/42y
Answer with Step-by-step explanation:
The height of the ball from the ground as a function of time is given by

The height of the ball at any instant of time can be found by putting the value of time 't' in the above relation as
Part a)
Height of ball after 2 seconds it is released is

Part b)
Height of ball after 4 seconds it is released is

If the two triangles are similar you can use a proportion to solve for the length of the legs.

=

Now, you would cross multiply to get
4x=18
Now, you simplify that using the division property of equality.
You end up with
x=4.5
Therefore, the legs of the triangle with a base of 9 inches will each be 4.5 units long.
12^3 would be one
12^3 = 1728
and 1728 / 24 = 72
