Which graph best represents the function f(x) = 3(1.5)x?
jok3333 [9.3K]

Answer:

B). graph of increasing exponential function going through point (0, 3)

Step-by-step explanation:

Given function is f\left(x\right)=3\left(1.5\right)^x

Now we need to find about which of the given choices best describes the given function. Where given choices are:

A). graph of increasing exponential function going through point 0, 2

B). graph of increasing exponential function going through point 0, 3

C). graph of increasing exponential function going through point 0, 1

D). graph of increasing exponential function going through point 0, 4

plug x=0 into given function

f\left(x\right)=3\left(1.5\right)^x

f\left(0\right)=3\left(1.5\right)^0=3(1)=3

Hence graph passes through point (0,3).

growth factor 1.5 is greater than 1 so that means it is increasing function.

Hence correct choice is:

B). graph of increasing exponential function going through point (0, 3)

Runner A is initially 5.1 km west of a flagpole and is running with a constant velocity of 8.5 km/h due east. Runner B is initia
Sati [7]

Find the total distance between the two runners:

5.1 + 4.1 = 9.2 km apart.

We want to calculate the distance each runner does:

Runner A distance = X km, rate = 8.5 km/ hr.

Time = X / 8.5

Runner B distance = (9.2 - x) Total distance between the runners minus what runner A runs equals where they meet).

Rate = 7.4 km/hr.

Time = (9.2-x) / 7.4

Now to find where they meet set the two equations equal:

x / 8.5 = (9.2-x) / 7.4

Cross Multiply:

7.4x = 78.2 - 8.5x

Add 8.5x to both sides:

15.9x = 78.2

Divide both sides by 15.9:

x = 78.2 / 15.9

x = 4.918 = 4.9 km.

Since X is the distance runner A runs, subtract that from his distance from the flag pole:

5.1 - 4.9 = 0.2

The runners meet 0.2 km west of the flag pole.
