You should’ve paid attention so don’t cheat
She can measure the temperature, if it will be equal or more than 100, then water is boiling otherwise not.
A)
rate of change from A to B = 48-0 / 1-0 = 48/1 = 48 ( feet per second)
rate of change from B to C = 64 -48 / 2-1 = 16 /1 = 16 ( feet per second)
B) the rate from A to B is greater. This tells me gravity starting acting on the rocket and started slowing it down
Answer:
(-4, 0) U (1, ∞)
Step-by-step explanation:
Set each factor EQUAL to zero to find the zeroes (since it is not actually equal to zero, you will use an open circle when graphing and an open bracket when writing in interval notation).
x = 0 x-1 = 0 x + 4 = 0
x = 1 x = -4
Next, choose a value to the far left, between each of the zeroes, and to the far right to evaluate if it makes a true statement when input into the given inequality.
far left (I choose -5): -5(-5 - 1)(-5 + 4) > 0 → (-)(-)(-) > 0 → negative > 0 FALSE
- 4 to 0 (I choose -2): -2(-2 - 1)(-2 + 4) > 0 → (-)(-)(+) > 0 → positive > 0 TRUE
0 to 1 (I choose 0.5): .5(.5 - 1)(.5 + 4) > 0 → (+)(-)(+) > 0 → negative > 0 FALSE
far right (I choose 2): 2(2 - 1)(2 + 4) > 0 → (+)(+)(+) > 0 → positive > 0 TRUE
I assume it would be y=65,536x
0=65,536(0)
65,536=65,536(1)
