Answer:
7x^2 -7x +3
Step-by-step explanation:
The synthetic division of the volume by the height is shown below.
(7x^3 -4x +3)/(x +1) = 7x^2 -7x +3
The area of the bottom face is 7x^2 -7x +3.
Answer:
7/3 ≤ x < 5.
Step-by-step explanation:
3 ≤ 3 x − 4 < 2 x + 1
Split this up into 2 inequalities:
3x - 4 ≥ 3
3x ≥ 7
x ≥ 7/3.
and
3x - 4 < 2x + 1
3x - 2x < 1 + 4
x < 5.
So it's 7/3 ≤ x < 5.
d) d = 2.5t, continuous
Explanation:
Jeff is traveling at the same pace, so he is moving at constant speed: its motion is a uniform motion, so the distance he covers (d) as a function of the time (t) is expressed by the law
(1)
where v is Jeff's speed.
We can find the speed from the initial data:
t = 2 hours
d = 5 miles
so, the speed is given by the ratio between the distance and the time
Therefore, equation (1) becomes
and the graph is continuous, because t can have any real value.
