Find all numbers for which the rational expression is undefined ​

Mathematics
1 answer:
Dafna1 [17]3 years ago
8 0

Answer:

{-3, 8}

Step-by-step explanation:

This rational expression is undefined wherever the denominator is 0.

Thus, our task is to determine the roots of x² - 5x - 24:

This expression factors as follows:  (x - 8)(x + 3) = 0

Setting x - 8 = 0 and solving for x yields x = 8.

Similarly, x + 3 = 0 yields x = -3.  

This rational expression is undefined for {-3, 8}.

The distance y (in miles) that a truck travels on x gallons of gasoline is represented by the equation y=18x The graph shows the
salantis [7]

Answer:

Car M:

50.4/2 = 25.2

car M uses up 1 gallon every 25.2 miles

Car P:

Just from the graph, you can see that it uses up 1 gallon every 30 miles

The two graphs vary the /miles slightly but it is around their zones of 25.2 and 30. It varies slightly because the cars may be traveling at a fast speed or slower speed thus using up more or less fuel by the time they've reached the recorded distances on the graphs.

An ice cream shop wants to be sure their cups and cones hold the same amount of
ella [17]

If the cone has the same width with the cup, the height of the cone will be 6 inches.

<h3>How to find the volume of cylinder and cone?</h3>

The cup is cylindrical.

Therefore,

volume of the cup = πr²h

where

  • r = radius
  • h = height

Hence,

volume of the cup = π × 1.5² × 2 = 4.5π

If the cone has the same width of the cup, the height of the cone can be calculated as follows;

4.5π  = 1  /3 πr²h

4.5π = 1 / 3 × π × 1.5² × h

4.5π = 0.75πh

h = 4.5π / 0.75π

h = 6 inches
