John paid $50 for renting a cycle for 5 hours. Which graph shows the relationship between the cost of renting a cycle for differ
SpyIntel [72]

Answer:

Graph A <==

Step-by-step explanation:

$ 50 for 5 hours......50/5 = 10...thats $ 10 per hr

so the equation would be : y = 10x...with x being the number of hrs and y being the total cost.

So ur x axis will be the hours and your y axis will be the total cost.

so ur answer is :the title of the graph is cycle renting. the x axis (the horizontal axis)...since it is the hours, will be labeled 0,1,2,3,4,5,6

the y axis (the vertical axis)...since it is the total cost, will be labeled  

0,10,20,30,40,50,60. points are plotted on (1,10),(2,20), and (3,30)

(NOT A MULTIPLE CHOICE)
Vsevolod [243]

9514 1404 393

Answer:

  a, b, c --- all <em>not</em> representative

Step-by-step explanation:

The question posed by the engineer is "are residents of the city in favor of ...".

The only representative sample is one from a pool that includes <em>all residents of the city</em>—not just those who (a) use the road, (b) live along the road, or (c)  own homes.

__

<em>Additional comment</em>

The engineer may want to refine the question. As posed, it would include children, homeless, and/or institutionalized residents of the city as well as drivers and tax-payers. In inclusive cultural traditions, "residents of the city" may also include animals, plants, water, air, and other holders of spiritual energy.

If the quadratic equation x2+18x+74=0 is rewritten in the form (x−p)2=q, what is the value of q?
PilotLPTM [1.2K]

Answer:

<em>C) 7</em>

Step-by-step explanation:

<u>Quadratic equation</u>

The quadratic equation can be written in several ways, one of the most-used is

ax^2+bx+c=0

To rewrite the equation in the form

(x-p)^2=q

we can complete squares and rearrange the terms as follows. The provided equation is

x^2+18x+74=0

The second term can be seen as

2(x)(9)

And the first two terms can be visualized as the square of a binomial

x^2+2(x)(9)+81-81+74=0

We have added and subtracted 81 to complete the square and not modify the equation. The new form of the equation is

(x+9)^2-7=0

Rearranging

(x+9)^2=7

Comparing with the general form written above, we find that

\boxed{q=7}
