Answer:
<h2>At the 7th bounce, the ball reached 2.3 feet height.</h2>
Step-by-step explanation:
The given expression is
This exponential function represents the movement of a bouncing ball after being dropped.
represents the bounce number.
So, at 7th bounce means 
, replacing this value in the function, we have
Therefore, at the 7th bounce, the ball reached 2.3 feet height.
Answer:
1/10
Step-by-step explanation:
1 minus 9/10 is 1/10
9514 1404 393
Answer:
4
Step-by-step explanation:
The function is of even degree. You can tell this because the end behavior is the same at both ends.
There are at least 4 zeros. There are 2 zeros of multiplicity 1 and one zero of multiplicity 2.
The crossings of the x-axis at x=-2 and x=3 have no flat spot, so the multiplicity must be 1; not 3, 5, or some other odd number.
You can tell the zero at x=1 is even multiplicity, because the graph does not cross the x-axis there. You can tell the multiplicity is only 2 because the curve is not flat enough for it to be 4 or more.
A polynomial function with 4 real zeros has a minimum degree of 4.
Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try!
