Answer:
Domain : 0 ≤ t ≤ 3
Range : -4 ≤ d ≤ 0
Step-by-step explanation:
The graph attached models the depth of submarine as a function of time.
Points on x-axis represent the time and points on y-axis represent increase in height of the submarine.
Domain of a function is represented by the points on x-axis.
Therefore, Domain : 0 ≤ t ≤ 3
Range of function is represented by te points on y-axis.
Therefore, Range : -4 ≤ d ≤ 0
The answer is 80,00 pounds.
Your answer will be D
As y = -(x+2)(x-1)
Thus the external negative sign will flip the positive 2 into a negative & negative 1 into a positive; Resulting, y=(x-2)(x+1)
Answer:
5mph
Step-by-step explanation:
Given that two cars are 40 miles apart at the beginning.
They started at the same time with speeds 48 mph and 56 mph respectively
Since both cars are travelling in the same direction,
Relative velocity = Speed of the behind car-Speed of the first car
=56-48 =8mph
To catch the I car, the second car has to travel a distance of 40 miles extra in the same time as the I car
i.e. speed to be made up by the second car = 40 miles
Relative velocity per hour = 8mph
Hence time taken to catch up = 
Answer:
Either 43 or 88
Step-by-step explanation:
45/3 = 15 (one witch)
21/3 = 7 (one broom)
12/3 = 4 (one spoon)
PEMDAS:
Equation: 15 + 7 x 4
if there are parenthesis and the equation looks like:
(15 + 7) x 4
the <u>answer is 88</u>.
if there is NOT parenthesis and the equation looks like:
15 + 7 x 4
the <u>answer is 43</u>.
