<u>Answer:</u>
Approximately after 2 hours the distance between the two cars will be 268 miles.
Solution:
We know
.
Here it is given that the speed of Car 1 is 65 mph and the speed of car 2 is 2.5 mph faster than car 1. It means that the speed of car 2 is (65+2.5) = 67.5 mph
We will use the below given equation to find out the time after which the distance between the two cars will be 268 miles.
Let ‘t’ be the time after which the distance between the two car will be 268 miles.
∴ A/Q, ![65t + 67.5t = 268](https://tex.z-dn.net/?f=65t%20%2B%2067.5t%20%3D%20268)
![132.5t = 268](https://tex.z-dn.net/?f=132.5t%20%3D%20268)
![t = \frac{268}{132.5}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B268%7D%7B132.5%7D)
![t = 2.02 hour](https://tex.z-dn.net/?f=t%20%3D%202.02%20hour)
Therefore, approximately after 2 hour the distance between the two cars will be 268 miles.
Answer:
Step-by-step explanation:
Let c ----> Cat
t ------> Table
f ---------> Frog
From the first figure,
c + t -f = 170 -----------(i)
From the second figure,
f + t -c = 130 ---------(ii)
Add (i) and (ii)
(i) c + t -f = 170
(ii) <u>f + t -c = 130</u> {c & -c and f & -f gets cancelled
2t = 300
t = 300/2
t = 150 cm
The table is 150 cm tall
Answer:
g(x) = 2x + 13
Step-by-step explanation:
To shift a function f(x) to the left, we add the unit h inside the function argument.
That is g(x) = f(x + h)
To shift a function f(x) to the right, we subtract the unit h inside the function argument.
That is g(x) = f(x - h)
Now, to shift f(x) = 2x - 1 to the left, we add the unit 7 inside the function f(x + 7) to have
g(x) = 2(x + 7) - 1
= 2x + 14 - 1
= 2x + 13
Answer:
2,856,271
Step-by-step explanation:
We presume your equation is intended to be ...
P = 1,030,000(1.12)^t
To find the prediction in 9 years, put 9 where t is and do the arithmetic.
P = 1030000(1.12^9) ≈ 2,856,271
In 9 years, the population is predicted to be about 2,856,271.
