Suppose you travel at 60 mph for 318 miles. How many hours will it take you to reach your destination
mel-nik [20]

Answer:

The time is 5.3 hours

Step-by-step explanation:

This is a distance problem

Distance = rate * time

We know the distance is 318 miles

The rate is 60 miles per hour.  We need to find the time

318 = 60 * t

Divide by 60

318 /60 = 60/60 *t

5.3 = t

The time is 5.3 hours

The graph of f(x) is shown below. where is f(x) < 0? write your answer in interval notation.
Bad White [126]

Answer:

The graph of  f(x) passes through (1,1) , (2,1.4...), (3,1.7....),(4,2)......

As, this curve is not linear.

To find the graph of a inverse function if a function is given

As we can see that ,

√1=1

√2=1.414..

√3=1.732..

√4=2

it means, √x=y is f(x).

So, to find the inverse of f(x), follow the procedure

Squaring both sides

Replace x by y and y by x to get inverse of f(x)

So,there will be two inverses of f(x)

1. x=√y

2. x= -√y

Domain of g(x)∈[0,∞], means y≥0.

Option A, 2nd graph below. and Option B. 3 rd Graph below is true regarding graph of g(x).

Nina [5.8K]

Answer:

72 cents.

Step-by-step explanation:

The expected winnings is the amount times the probability that you will get that amount.

2,000 * (1/10,000) = 2,000 / 10,000 = 2 / 10 = 0.2.

700 * (4 / 10,000) = 2,800 / 10,000 = 28 / 100 = 0.28.

300 * (8 / 10,000) = 2,400 / 10,000 = 24 / 100 = 0.24.

0.2 + 0.28 + 0.24 = 0.72.

Hope this helps!
