P L E A S E H E L P!!!!!!!!!
Nostrana [21]

Answer:

The equation that matches the function shown is option;

C. y = sin\left (\dfrac{1}{2} \cdot x\right)

Step-by-step explanation:

The given graph of the function is a sinusoidal graph

The values of 'x' and 'y' coordinates at the maximum, x-intercept and minimum points are given as follows;

x, {}      y

0    {}   0

π {}       1

2·π   {} 0

3·π {}    -1

4·π {}    0

We note that sin(π/2) = 1, sin(π) = 0 sin(3·π/2) = -1, and sin(4·π/2) = sin(2·π) = 0

Therefore;

y = the sine of half the x-value

Which is presented as follows;

y = sin\left (\dfrac{1}{2} \cdot x\right).

I need help with these two trigonometry problems.
Sloan [31]

Answer:

B \approx 32.1\°; A \approx 39.0\°

Step-by-step explanation:

Sine theorem: in any triangle, the ratio between a side and the sine of the opposite angle is constant

\frac{sin\ \alpha}a = \frac{sin\ \beta}b =\frac{sin\ \gamma}c

In our case, for the left triangle,

\frac {sin\ 103\°}{11} =\frac{sin\ B} 6 \rightarrow sin\ B = \frac6{11} sin\ 103\°

Time to grab a calculator and crunch numbers. Double check your calculator is in degrees and not in radians (plug in sin 30°, if you're getting 0.5 you're good) and you will get

sin\ B \approx 0.53 \rightarrow B \approx 32.1\°

Same difference with the right triangle. With the same calculations

sin\ A = \frac{26}{41} sin 83\° \approx 0.68 \rightarrow A \approx 39.0\°

The double number line shows the amount of time a hen needs to lay 1 egg.
Scorpion4ik [409]

I realize the double number line in this exercise can be as shown in the attached image, in that case, the table, correctly completed is:

Eggs      Time (hours)

 3                   <u>75</u>

 <u>4</u>                  100

 12                <u>300</u>

Method to complete the table.

First, you must see the double number line (attached image), in this we identify a hen needs 25 hours to lay 1 egg, by this reason, to identify the time required for a certain number of eggs, just multiply the number of eggs by 25 (the number of hours shown on the double number line), then:

  • 3 * 25 = <u>75</u>
  • 12 * 25 = <u>300</u>

To calculate the number of eggs taking into account the time, you must divide the hours by 25:

  • 100 / 25 = <u>4</u>

In this way, <u><em>you can check that the answers are 75, 4, and 300 respectively, to complete the table in the correct form</em></u>.
