Hello from MrBillDoesMath!

Answer:

4 sin(70) which is approximately 3.76

Discussion:

sin(70) =

side opposite angle/ hypotenuse =

?/4.

As sin(70) = ?/4, multiplying both sides by 4 gives

? =4 sin(70) which is approximately 3.76

Thank you,

Michael ran 655 feet in 19 seconds jasmine ran 1 mile in 4 minutes and 24 seconds in miles per hour and to the nearest tenth how

Natalka [10]

Answer:

Step-by-step explanation:

<h3>Step 1: Convert miles to feet</h3>

First, we need to convert the miles to feet keeping in mind that:

1 mile = 5,280 feet

655 ft 19 sec

5,280 ft 4 min 24 sec

<h3>Step 2: Divide the distance by the time to find the unit rate</h3>

3,447 feet per minute

1,245 feet per minute

<h3>Step 3: Convert minutes to hours</h3>

206,820 feet per hour

74,700 feet per hour

<h3>Step 4: Convert feet to miles</h3>

39.17 miles per hour

14.15 miles per hour

To find how much faster Michael ran, we need one more step.

<h3>Step 5: Subtract smaller amount from larger amount</h3>

39.17 - 14.15 = 25

I'm always happy to help :)

Use the vertical line test to determine if the graph below represents a function. If it is not a function, tell where the vertic

Step2247 [10]

Answer:

see attached

Step-by-step explanation:

The vertical line test for a function passes when, if you draw a vertical line which intersects the graph, the line intersects the graph at ONLY ONE point.

It is quite clear that for all positive values of X, any vertical line will intersect the graph at 2 points, thereby failing the vertical line test for a function.
