Hey there mate :)

As per question,

Options (a), (b) and (d) are correct.

<h3>Proof :-</h3>

(a) <em><u>The cost per visit to a community pool.</u></em>

Considering x = number of visits to the pool

a = fixed cost of visit.

So, the cost per visit to the pool y will be ax

Therefore, this represents a linear function.

And

<em><u>The neighborhood charges a yearly fee to use the pool.</u></em>

Assuming x = number of years

a = fixed fee to use the pool

So the yearly fee to use the pool y will be ax

Therefore, this represents a linear function.

(b) <em><u>The cost to attend a show at the local theater. Tickets are $12 each.</u></em>

Let x = number of shows

Let the cost of one show = $12.

Now, the cost of x shows y will be 12x

So, it represents a linear function.

(d) <em><u>The distance a bicyclist travels when cycling at a constant speed of 30 mph. </u></em>

Assuming <em>x</em>= time

Speed = 30 mph.

Since the distance (y) is given as:-

Distance = Speed×time, so,

<em>=> y = 30x</em>

Hence, this also represents a linear function.

<u>Hence, all correct option are proved</u>

How do you convert 7/6 into a mixed number
Natali [406]
Wel its kinda difficult to say but look on how much times 6 can fit into 7 which is 1 but that will be 6,so in order to become seven you need 1 which is our left over number,so in the end you will get 1 whole and 1/6 and you use the leftover number as your numerator and just leave the 6 as it was.Whoof that was long but its no nearly as long as i explain it.

Suppose Marcy's rectangular laptop measures 12 inches by 9 inches. Find the diagonal measurement from corner A to corner B.
astraxan [27]

Answer:

the diagonal measurement from corner A to corner B=15 inches

Step-by-step explanation:

as we know that the loptop has the shape of a rectangle that means all it's angles are right angles. so we can use the pythogoras theorem to find out the diagonal of the rectangle.

let us denote the diagonal of rectangle by D and the sides of rectangle be denoted by X=12 and Y=9

so by using pythogoras theorem we have,

D^{2} =X^{2} +Y^{2}

D^{2}=225

D=15

Hence the diagonal measurement from corner A to corner B is 15 inches.
