Length x width is the formula.
so 18 x 18 for 7.
22 x 24 for 8.
and 8 would probably be 5 x 5 to equal 20. so the length and width would be 5 and 5 because 20 is the area

You and your friends are going to the movies, and you plan to buy tickets for your friends because there is a discount
LekaFEV [45]

Answer:

y = 9.50 + 6.00n

Step-by-step explanation:

This equation shows that the base rice that you must pay is $9.50 (the cost of your ticket). $6.00n represents the cost of however many additional tickets you purchase for n friends. Say 3 friends decide to come, your n value is 3.

You would need to do the following to determine the price you need to pay for 3 friends:

6.00(3) = 18.00  (this is how much you'd pay for 3 friends)

You must add your ticket price to $18.00 to find y (the total amount you must pay for yourself and your 3 friends). So you must do the following:

y = 9.50 + 6.00(3)

y = 9.50 + 18.00

y = 27.50 (this is the total price you'll pay for everyone attending

Hope this helps :)

Please help asap! thx

Answer:

y = 0

Step-by-step explanation:

The given sinusoidal equation is y = 2 \cdot sin \left(\dfrac{\pi}{2} \cdot x + 3 \right)

The general form of the sin function is presented as follows;

y = A·sin(B·(x - C)) + D

Where;

A = The amplitude

The period, T = 2·π/B

The frequency, f = B/2·π

C = The horizontal shift

D = The vertical shift

By comparison with the given sine function, we have;

The amplitude, A = 2

The frequency, f = B/2·π = π/2/(2·π) = 1/4

The frequency, f = 1/4 Hz

C = The horizontal shift = 3/(π/2) = 6/π

The vertical shift, D = 0

Given that the mid line of the parent function, sin(x), is the line y = 0, and that the vertical shift is 0, the midline of the function, y = 2 \cdot sin \left(\dfrac{\pi}{2} \cdot x + 3 \right), is therefore, the line;

y = 0.

Look at the graph below: First line joins ordered pairs negative 4, 3 and 2, negative 3. Second line joins negative 4, negative
slavikrds [6]

Answer:

Part B shaded below first line and above second line.

Step-by-step explanation:

The first inequality corresponds to the second line (-3 = -4+1, for example) The ≥ symbol in that inequality tells you it will be satisfied by y values above those on the line.

The second inequality corresponds to the first line (-4+3 = -1, for example) The ≤ symbol in that inequality tells you it will be satisfied by y values below those on the line.

Hence the solution set is those values shaded below the first line and above the second line — matching Part B.
