Multiply 2 by 7, which is 14, and add it to the 4 in the numerator. The fraction becomes 18/7
Answer:
t = 1 s
Step-by-step explanation:
The function models the height of the ball after t seconds is given by :

We need to find how many seconds does it take for the ball to reach its maximum height.
For maximum height put dh/dt = 0

So,
32-32t = 0
t = 1
So, it will take 1 second to reach its maximum height.
Answer:
it would take 21 minutes per mile
Step-by-step explanation:
Answer: The answer is D
Step-by-step explanation:The reason for this is because 48.6 is closer to 50 and also when its rounded its about 50 not 40.In addition,0.7 is turned into 1 because its higher .5 which means it would be consider 1.For example, if the number is 16.6 it will be rounded up to 17.

Answer:
x^3 -14x^2 -6
Step-by-step explanation:
Your expression is the difference of two polynomials. The parentheses can be removed by using the distributive property. The minus sign outside the second set of parentheses applies to each term inside parentheses.
-5x^2 +3 +x^3 -9x^2 -9
Now, you can group like terms. In "standard form", the degrees of the terms decrease from left to right.
x^3 +(-5x^2 -9x^2) +(3 -9)
And combine like terms.
x^3 -14x^2 -6 . . . . . simplified form of the given expression
