Hi, there.
____
Coefficients: numbers multiplied by variables
Like Terms: terms with the same variables/exponents
Constant Terms: numbers
Thus
is your desired expression
Hope the answer - and explanation - made sense,
happy studying.
The function h(t) = -16t² + 72t will equal zero when the ball hits the ground:
-16t² + 72t = 0. Solving for the time, t, we factor -16t² + 72t : 16t (-t + 4.5) = 0.
This results in t = 0 and t = 4.5 sec. The ball hits the ground after 4.5 sec.
Problem 12.
Starting with A:(-5,3): Reflecting A over the y-axis results in B: (5,3). Translating B 3 units to the right results in C: (8,3). Finally, translating C down by 4 units results in D: (8,-1) (answer).
Answer:
60/90, 6/9, 30/45, 20/30, 2/3 are equivalent fractions.
The given equation of sphere is
We have to use completing the square method , and in that method, we have to divide 12x ,-4y,2z by 2, square the results, and add the reult obtained after squaring to both sides. That is
So here the center is (-6,2,-1) and radius is 2 .
