The time of takeoff of this hovercraft would be 0 seconds, as if you were starting a timer. So, if you plug in 0 for x (unit for seconds) in your equation, it will look like this:
h(0) = -3(0 - 3)² + 108
Parenthesis first
h(0) = -3(-3)² + 108
Exponents next
h(0) = -3(9) + 108
Multiplication
h(0) = -27 + 108
Combine like terms
h(0) = 81: The height of the hovercraft at the time of takeoff is 81 meters!
Hope this helps :)
2(a+bc)=2a+2bc
3.(ab-cb-ba+bc)= 3ab-3cb-3ba+3bc
Since the brackets and multiplication have a higher order than the rest.
Cb=Bc
Ab=ba
Ac=Ca
Because multiplication is commutative.
2a+2bc + cb +ab + ac -(3ab-3cb-3ba+3bc)
2a + 2bc + cb + ab + ac(+ -3ab - - 3cb - -3ba +-3bc)
2a + 2bc + cb + ab + ac -3ab + 3cb + 3ba -3bc
2a + (2bc-3bc +cb + 3cb ) + (ab -3ab + 3ba) + ac
=2a + 3cb + ba+ ac OR 2a +3bc + ab + ac
The Or is just a different way to write it.
Hope this helps
Answer:
E. is not a polynomial
Step-by-step explanation:
Because the degree of x is 2/5 which is not a polynomial.
On a number line that represents an inequality, if it has a closed circle the inequality will say or show a greater/ less than or equal to or it will say the number is at least this. The at least means that it could be more than this but it could also be this number.
2 - 3/2(x) greater than or equal to 5 1/2 - This one is the last option
(2 * x) + (-2) greater than or equal to 8 - This one is the first option
7 - (4 * x) greater than 13 - The second one
4 + (3 * x) less than 19 - The third one
