A class of 24 students is planning a field trip to a science museum. A nonrefundable deposit of $50 is required for the day-long

erica [24]

Answer:

Option A , C ,D

Step-by-step explanation:

A nonrefundable deposit required for the day-long program = $50

Charge per person = $4.50

Let us suppose the number of students is s

So, Charge for s students = $4.50s

Let c denotes the total cost

So, total cost : $c=50+4.50s$

So, Option A is correct : The linear model is f(s) = 4.5s + 50.

Total cost : $c=50+4.50s$

We are given that total students are 24

Substitute s = 0

So, $c=50$

Substitute s = 24

$c=50+4.50(24)$

$c=158$

So, Option C and D is also correct.

C. The domain is {x| 0 ≤ x ≤ 24}

D .The range is {y| 50 ≤ y ≤ 158}

Refer the attached figure

The graph is discrete .

So, Option E is incorrect.

A pool measuring 16 meters by 22 meters is surrounded by a path of uniform width, as shown in the figure. If the area of the po

lesantik [10]

Let X be the width of the path.

The width of the path would be the width of the pool plus 2x, so 2x +16

The length of the path would be the length of the pool plus 2x, so 2x+22

The total area is 832 square feet.

Area is found by multiplying the length by the width.

So you have:

(2x+16) (2x+22) = 832

Use the Foil Method:

(2x+16) (2x+22) = 4x^2 +76x+352

Now you have:

4x^2 +76x+352 = 832

Subtract 832 from both sides:

4x^2 +76x+352-832 = 0

Simplify:

4x^2 +76x -480

Factor the left side:

4(x-5)(x+24) = 0

Divide both sides by 4:

(x-5)(x+24) = 0

Set both parenthesis to equal 0 and solve for x:

x=5 and x = -24

The width of the path cannot be a negative number, so the width is 5 meters.

The value of x is 8 from the diagram given.

<h3>How do you calculate the sides of similar triangles?</h3>

The corresponding sides of a similar triangle are said to be in proportion if and only if the corresponding angle are also equal.

To calculate the side of line x (|x|), we have to determine the ratios of the corresponding sides as:

$\mathbf{\dfrac{BC}{DC} = \dfrac{AC}{EC}}$

$\mathbf{\dfrac{x}{10} = \dfrac{12}{15}}$

x = 120/15

x = 8

Therefore, we can conclude that the value of x is 8.
