Answer: The required factored form of the given expression is
Step-by-step explanation: We are given to find the factored form of the following quadratic expression :
Since the given quadratic expression does not contain the constant term, so first we should take common the x-term and then factorize.
From equation (i), we have
Thus, the required factored form of the given expression is
Answer:
40 feet
Step-by-step explanation:
We know that the area of a rectangle is represented as , where l is the length and w is the width.
We already know the width, and we know the area, so we can plug these values into the equation.
Our goal is to now isolate the variable l, and to do this we can divide both sides by 6.
Hope this helped!
Answer:
The instantaneous velocity after eight seconds is 9 m/s
Step-by-step explanation:
Given as :
The ball shot upward with velocity of 15 m/s
The height of the ball after t sec is given as h(t) =
Now, The instantaneous velocity after 8 sec =
Or, The instantaneous velocity =
or, The instantaneous velocity =
Now at t = 8 sec
The instantaneous velocity = 5 + 4 = 9 m/s
Hence The instantaneous velocity of ball at t = 8 sec , is 9 m/s Answer
