If Fred rides 17 miles an hour and rides for 4 hours, then you multiply 17 miles by 4 hours to determine total miles. Then multiply total miles by the $ per mile to determine total $ made.

Step 1:
=17 miles * 4 hours
=68 total miles

Step 2:
=68 total miles * $1 per mile
=$68 total money made

Hope this helps! :)

Please help me with this question it is due today! What value of m makes the system show perpendicular lines? Explain.
Lady bird [3.3K]
M = -2

In perpendicular lines, the slopes are opposite reciprocal. This means you flip the sign (from + to - or from - to +) and flip the numerator and denominator.

So 1/2 becomes negative, and 2/1 = 2

So the slope is -2

Help please I realy nead help
Makovka662 [10]

Answer:

B) 77.5 square feet

Step-by-step explanation:

cut shape into rectangle and triangle

area of rectangle = x*y

area of rectangle = 5*13

area of rectangle = 65

area of triangle = (z-x)*(y-w)/2

area of triangle = 5*3/2

area of triangle = 7.5

Total area = 65 + 7.5

Total area = 77.5, B)

The linear relationship is y = 20x, 0 ≤ x ≤ 17.5 and the quadratic relationship is y = -16x² + 288, 0 ≤ x ≤ 3√2

<h3>The equations that represent the relationships</h3>

<u>The linear relationship</u>

When making the trip up, we have:

Rate = 20 feet per seconds

This means that the relationship is:

Distance = Rate * Time

So, we have:

y = 20x

The height of the tower is 350.

So, we have:

20x = 350

Divide by 20

x = 17.5

Hence, the linear relationship is y = 20x, 0 ≤ x ≤ 17.5

<u>The quadratic relationship</u>

The quadratic equation can be represented as:

y = -0.5ax² + vx + h

Where:

  • a = acceleration due to gravity = 32
  • v = velocity = 0
  • h = height = 288

So, we have:

y = -0.5 * 32x² + 0 * x + 288

Evaluate

y = -16x² + 288

When you get to the ground level, we have:

-16x² + 288 = 0

Subtract 288 from both sides

-16x² = -288

Divide by -16

x² = 18

Take the square root of both sides

x = ±3√2

Remove negative domain

x = 3√2

Hence, the quadratic relationship is y = -16x² + 288, 0 ≤ x ≤ 3√2
