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>

Find the length of GF
Cerrena [4.2K]
By the Pythagorean Theorem:

The square of the hypotenuse (longest side) of a right triangle is equal to the sum of the side lengths squared, or mathematically:

h^2=x^2+y^2, where x and y are the side lengths and h is the length of the hypotenuse, in this case:

9.4^2=6.8^2+GF^2

GF^2=9.4^2-6.8^2

GF^2=42.12

GF=√42.12 units

GF≈6.49 units (to nearest hundredth of a unit)

John buys 3 pounds of cherries and 2 pounds of bananas he pays a total of $24.95 the bananas cost $6.50 less per pound than the
Murrr4er [49]

John will pay $8.68 for the combined cost of 1 pound of banana and 1 pound of cherries.

Let: b=cost of banana per pound and c=cost of cherries per pound

Equation 1: For 3 pounds of cherries and 2 pounds of bananas, John pays a total of $24.95.

3c + 2b =$24.95

Equation 2: The cost of bananas is $6.50 less than a pound of cherries.

b= c - $6.50

We can substitute the second equation into the first one to solve for the cost of cherries per pound.

3c + (2)(c-$6.50)= $24.95

3c + 2c -$13.00 = $24.95

5c = $24.95 + $13.00

c = $7.59

Substituting the value of c to the second equation to solve for b.

b= $7.59 - $6.50 = $1.09

The combined cost of 1 pound of banana and 1 pound of cherries is $1.09 + $7.59 or $8.68.

First you find how much the shape has dilated. To d ok that you divide the size of the size already given to you from the bigger shape from the same did if the smaller shape. So 58÷6=9.7. The shape grew by 9.7. To find x you use the similar side of the other shape again and multiy that size by 9.7. So 9.7×3=29.1

x=29.1

The surface area of a cylinder is the sum of the area of the two ends and the lateral area.
.. surface area = 2*(end area) +(lateral area)
.. = 2*(π*r^2) +(2π*r*h)
.. = 2π*r*(r +h)
.. = 2*3.14*(8 in)*(8 in +8 in)
.. = 3.14*256 in^2
.. ≈ 803.8 in^2

The 3rd selection is appropriate.
