Answer:

Step-by-step explanation:

A many-to-one function is a function that have y-values associated to more than one x-value.

Graphically speaking, if I draw an horizontal line through the graph, my horizontal line would cross the graph at least twice.

In the pictures, we can see that A is a parable, if I draw an horizontal line above y = 0, my line will go through the parable twice. For example, in y = 10 it will cross the parable at the point (-3,10) and (3,10). Therefore, this is a many-to-one graph.

The second picture is a one-to-one graph since there is only one y-value associated to each x-value.

The third graph is not even a function because by definition of function, each element of x should be associated with ONE element of y. In this case, x= 5 and x = 9 are associated to more than one y elements (the vertical lines that form two sides of the square) and therefore is not a function.

Answer:

none of the graphs shown

Step-by-step explanation:

A "many to one" function will be a graph that contains a single horizontal line and no points that can be on the same vertical line. Graph C has horizontal lines, but maps "many to many", rather than "many to one."

The ac is a leg of the right triangle <br> True <br> False

Vinil7 [7]

Answer:

False

Step-by-step:

The hypotenuse of the triangle is the side opposite to the right angle. The legs are the other two sides of the triangle. Since AC is on the opposite side of the right angle, it is the hypotenuse and therefore not a leg. Hope this helps!

yawa3891 [41]

Answer:

a. Blank time = 7:12 am

b. Blank Minutes = 30 minutes

Step-by-step explanation:

The individual got downstairs 25 minutes after 6:47am

Hence Blank time = 6:47am + 25 minutes = 7:12 am

To calculate amount of blank minutes he spent reading books

7:42am - 7:12am = 30 minutes

On average, a pair of bike tires can last 18 months if used every day. The length of time bike tires can last is exponentially d

aleksandr82 [10.1K]

Answer:

We conclude that eighty percent of bike tires last at most 14.4 months.

Step-by-step explanation:

We know that a pair of bike tires can last 18 months if used every day.

We calculate how much eighty percent of the tire will last in months.

We have the following proportion:

$18:100\%=x:80\%\\\\100x=18\cdot 80\\\\100x=1440\\\\x=\frac{1440}{100}\\\\x=14.4$

We conclude that eighty percent of bike tires last at most 14.4 months.

Cal is measuring temperature changes in four substances over different time periods as part of a school project. Which data show

djyliett [7]

Answer:

C) The third table. K= 5

$C)\frac{10}{2}=\frac{15}{3}=\frac{25}{5}=\frac{40}{8}=k= 5$

Step-by-step explanation:

1) Below there are the missing data:

A proportional relationship through a constant k. It is obtained when we divide:

$k=\frac{y}{x}$

2)In this case, when we divide the temperature (T) by the time (h).

$k=\frac{T}{h}$

3)So, examining the table below we are searching for a ratio k common to all measures (temperatures over hour).

$A) \frac{12}{3}\neq\frac{25}{5}\neq\frac{36}{6}\neq\frac{81}{9}\\B) \frac{22.5}{3}\neq\frac{30}{4}\neq\frac{52.5}{7}\neq\frac{67.5}{8}\\C)\frac{10}{2}=\frac{15}{3}=\frac{25}{5}=\frac{40}{8}=k= 5\\D)\frac{8.5}{2}\neq\frac{22.5}{5}\neq\frac{28.5}{7}\neq\frac{36}{8}$
