A) 1 km =1000 m
5 km*1000 =5000m
=5000:400. = 50:4

b) 1 hours = 60 minutes
2 hours *60 minutes =120 minutes
=120 minutes :160 minutes =(12:16)/4
=3:4

2. Determine if either of the following equations are functions? Draw the graphs and explain how

nekit [7.7K]

Answer:

Both equation represent functions

Step-by-step explanation:

The function is the relation that for each input, there is only one output.

A. Consider the equation

$y=-\dfrac{3}{5}x+2$

This equation represents the function, because for each input value x, there is exactly one output value y.

To check whether the equation represents a function, you can use vertical line test. If all vertical lines intersect the graph of the function in one point, then the equation represents the function.

When you intersect the graph of the function $y=-\dfrac{3}{5}x+2$ with vertical lines, there will be only one point of intersection (see blue graph in attached diagram). So this equation represents the function.

B. Consider the equation

$y=x-x^2$

This equation represents the function, because for each input value x, there is exactly one output value y.

When you intersect the graph of the function $y=x-x^2$ with vertical lines, there will be only one point of intersection (see green graph in attached diagram). So this equation represents the function.

Your graphing the speed your car goes on the interstate from the time you enter the ramp until you arrive at the next exit ramp

inysia [295]

Answer:

1 minute on the x-axis; 10 mph on the y-axis

Step-by-step explanation:

The distance between exit ramps is less than 6 miles and since you are traveling at 70 mph on the highway you should get there in less than 5 mins, so the scale on the x-axis should be 1 minute. Since you have 10 tick marks on the y-axis and will be going at a speed of 70 mph at some point, the scale on the y-axis should be 10 mph (100 mph total). A good scale would be 1 minute on the x-axis; 10 mph on the y-axis.

Can someone please help me?<br>Need this for today!

Vesnalui [34]

Answer:

First one: Degree of 13, type monomial

Second one: Degree of 5, type trinomial

Third one: Degree of 8, type trinomial

Step-by-step explanation:

The degree of a polynomial is determined by the highest degree of its individual terms. To determine the degree of a term, add up the power values of the variables.

The type of the polynomial is determined by how many terms are being separated by an addition sign ( a subtraction sign is just the addition of the inverse of a number).

One term: Monomial

Two terms: Binomial

Three terms: Trinomial

Four terms and so on: Generally just called polynomials

Car A is rated at 32 mi/gal (miles per gallon) for city driving and 29 mi/gal for highway driving. Car B is rated at 27 mi/g

Irina18 [472]

The gallons of gas that each vehicle would consume for the different amounts of driving are as follows:

a) For 300 mi of city driving plus 100 mi of highway driving, car A will consume <u>12.825 gallons</u> of gas, while car B will consume <u>14.05 gallons</u> of gas.

b) For 100 mi of city driving plus 300 mi of highway driving, car A will consume <u>13.475 gallons</u> of gas, while car B will consume <u>12.52 gallons</u> of gas.

<h3>Data and Calculations:</h3><h3>Rating (miles per gallon)</h3>

City Driving Highway Driving

Car A 32 mi/gal 29 mi/gal

Car B 27 mi/gal 34 mi/gal

<h3>Miles of Driving</h3>

City Driving Highway Driving

a) 300 mi 100 mi

b) 100 mi 300 mi

<h3>Car A's Consumption of Gas:</h3>

City Driving Highway Driving Total

a) 9.375 gal.(300/32) 3.45 gal. (100/29) 12.825 gal.

b) 3.125 gal.(100/32) 10.35 gal (300/29) 13.475 gal.

<h3>Car B's Consumption of Gas:</h3>

City Driving Highway Driving Total

a) 11.11 gal. (300/27) 2.94 gal. (100/34) 14.05 gal.

b) 3.70 gal. (100/27) 8.82 gal. (300/34) 12.52 gal.

Thus, different driving ratings (miles per gallon) show the differences in gas consumption by vehicles in city driving and highway driving.
