Answer:
Step-by-step explanation:
To explain how to approach this question, I am going to place letters in the blank spaces:
First, compare the <u>coefficients</u> of the x² terms on both sides of the equation:
Therefore, we need to choose any two numbers in place of a and d whose difference is -5:
⇒ a = 2 and d = 7 as 2 - 7 = -5.
Similarly, upon comparing the <u>coefficients</u> of the x terms, we can see that there is no x term on the right side of the equation. Therefore, we need to choose numbers in place of b and e for which the difference is zero. So b and e should be the <u>same number</u>:
⇒ b = 2 and e = 2 as 2 - 2 = 0.
Finally, compare the constant term on both sides of the equation:
Therefore, we need to choose any two numbers in place of c and f whose difference is -14:
⇒ c = 1 and f = 15 as 1 - 15 = -14.
Plug in the numbers in place of the letters on the left side of the equation:
<u>Check</u>
Remove the brackets:
Collect like terms:
Combine like terms:
Hence proving that the left and right sides of the equation are the same.
It would be: 3 * 0.53 = 1.59
In short, Your Answer would be 1.59 lbs
Hope this helps!
average rate of change of work from max. height unitil it reaches the ground 4 ≥ t .
<h3>WHAT IS AVERAGE RATE ? </h3>
The average rate at which one quantity changes in relation to another's change is referred to as the average rate of change function. A method that determines the amount of change in one item divided by the corresponding amount of change in another is known as an average rate of change function.
<h3>CALCULATION</h3>
h(t)=-16t^2+144t
= 16t [ 4 - t ]
4 - t ≥ t
domain is (0,4)
t is the time , time must be positive so domain starts from zero .
