The opposite of something means to change this signed that is with the number.
If it is a positive number, the opposite would be negative.
So in this example, if it's the opposite of positive 5, that is -5. The opposite of -5 would be positive 5.
The equation that shows this correctly would be D.
Answer:
161
Step-by-step explanation:
350*0.46=161
(7, 0) and (11, 3) HOPE THIS HELPED!! <span>( ⸝⸝•ᴗ•⸝⸝ )੭⁾⁾</span>
Step-by-step explanation:
initial speed = 272 ft/s
h = -16t² + 272t
a. 1120 = -16t² + 272t we change a bit into
16t² - 272t + 1120 = 0 then divide all with factor 16
t² - 17t + 70 = 0
(t - 10)(t - 7) = 0
t = 10 and t = 7
7 s when it goes up and 10 sec when the rocket goes down.
b. 1152 = -16t² + 272t we change a bit into
16t² - 272t + 1152 = 0 then divide all with factor 16
t² - 17t + 72 = 0
(t - 9)(t - 8) = 0
t = 9 and t = 8 sec
c. since the answer of a and b is:
7 sec and 8 sec the rocket goes up but at 9 sec and 10 sec the rocket goes down then we can take conclusion that the maximum height is reached at 8.5 s
so how long the rocket in the air?
goes up : 8.5 sec
goes down : 8.5 sec
total = 17 sec
Answer: -3
The coefficient is the number that is getting multiplied by the variable
