Answer:

the correct answer is marked

Step-by-step explanation:

The graph ranges vertically between 9 and 15, starting at 9 (the minimum) when x=0. The minimum appears again at x=350.

This means the vertical offset is (9+15)/2 = 12, and the amplitude is (15 -9)/2 = 3. The period is 350, so the coefficient of x is (2π/350). All of the answer choices agree on these parameters.

So, the selection comes down to an understanding of how the sine and cosine curves vary. The sine curve starts at zero and increases from there. The cosine curve starts at its maximum (1) and decreases. Here, the curve starts a its minimum and increases, so could be the opposite of the cosine function.

y = -3cos(2πx/350) +12 . . . . . . matches choice C

The eatery restaurant has 200 tables a recent evening there were reservations for 1/10 of the tables how many tables were reserv

leonid [27]

1. 20 tables are reserved.

2. I know this because...
- If I make an equivalent fraction to 1/10, using 200 as the denominator, I get:
· 1/10 x 20 = 20/200 tables are reserved.

Hope this helped! :)

Select three ratios that are equivalent to 8:58:58, colon, 5. Choose 3 answers: Choose 3 answers: (Choice A, Checked) A 16:1016:

Snezhnost [94]

Answer:

I think the reference ratio given is wrong so the right one is

8:508:508:5

Step-by-step explanation:

Given that,

8:58:58:5

We want to find which of the option is equivalent to the given ration

Option A.

16:1016:1016:10

Divide each of the ration by

Then,

16÷2:1016÷2:1016÷2:10÷2

8:508:508:5

Option B

50:8050:8050:80

Divide through by 10

50÷10:8050÷10:8050÷10:80÷10

5:805:805:8

Option C

48:3048:3048:30

Divide through by 6

48÷6:3048÷6:3048÷6:30÷6

8:508:508:5

Option D

32:2032:2032:20

Divide through by 4

32÷4:2032÷4:2032÷4:20÷4

8:508:508:5

Option E

64:3564:3564:35

Divide through by 8

64÷8:3564÷8:3564÷8:35÷8

This doesn't have a factor

So the ratio still retain

64:3564:3564:35

So to analyse the solution,

I believe the reference ratio given is wrong, so I think the reference ratio about be 8:508:508:5

So, from the option, the equivalent to the given ratio are options A, C, and D

A golf store purchases a set of clubs at a wholesale price of $250. Mr. Edmond learned that the clubs were marked up 200%. Is it

Black_prince [1.1K]

Answer:

Yes it is possible to have an increase of 100%.

Retail price is 83.4$

Step-by-step explanation:

250 = x + (200% of x)

250 = 300% of x

so basically 250$ = 3x

250/3 = 83.3333334

So you can round it to $83.4

Hope this helps. I'm not entirely sure this is true but I hope it is.
