Answer:
It accelerated at 5 km/hr/s or the car was going 5 km/h faster each second.
The car was speeding up
Step-by-step explanation:
To find an estimated acceleration, you just take the speed it got to and divide it by the tie it took to get there
<em>s</em>/<em>t = a</em> <---- where <em>s = </em>speed <em>t = </em>time <em>a =</em> acceleration
We know it was speeding up because it was at a red light so it was stopped. Then when it turned green, then the car would have started moving
Answer:
AB = 83
Step-by-step explanation:
The mid-point of any segment divides the segment into two equal parts
∵ B is the midpoint of segment AC
→ That means B divides AC into two equal segments AB and BC
∴ AB = BC
∵ AB = 12x + 11
∵ BC = 14x - 1
→ Equate them
∴ 14x - 1 = 12x + 11
→ Subtract 12x from both sides
∵ 14x - 12x - 1 = 12x - 12x + 11
∴ 2x - 1 = 11
→ Add 1 to both sides
∵ 2x - 1 + 1 = 11 + 1
∴ 2x = 12
→ Divide both sides by 2
∵ 
∴ x = 6
→ To find AB substitute x by 6 in its expression
∵ ab = 12x + 11
∵ x = 6
∴ AB = 12(6) + 11
∴ AB = 72 + 11
∴ AB = 83
For the answer to the question above, <span>Well, first let us put up a functional equation. </span>
<span>Since this is an exponential function, it'll be: f(t)=54,000*1.03^t </span>
<span>But we want to know how many wolves there were 10 years ago. </span>
<span>For that, we simply "turn time around", as in: f(t)=54,00*1.03^-t </span>
<span>This displays a decreasing number of wolves, as you turn back time. </span>
<span>Now we simply calculate 54,000*1.03^-10 </span>
<span>which is approximately 40,200?</span>
Answer:
h = 39.8 inches
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2h
We know the diameter d = 32 so the radius is 1/2 of the diameter
r = d/2=32/2 = 16
32000 = pi (16)^2 h
32000 = 256 ( pi) h
Divide each side by 256 pi
32000 / 256 pi = h
125/pi = h
Using 3.14 for pi
39.8089172 = h
Rounding to the nearest tenth
h = 39.8 inches
