Answer:

a = 10.36m

B = 47.7º

C = 90º

Step-by-step explanation:

we know the angle of A so we do the sin of A; Spoiler: its 0.67

0.67 = a / 15.4

0.67 * 15.4 = a

a = 10.36

----------

B = 90 - 42.3 = 47.7º

Graph x=−6. Please help this is very confusing

attashe74 [19]

This is how you would draw x=-6 on a graph:) (Its the red line)
You have to imagine it as (0, -6) so you would just draw that line:)

Determine whether each ordered pair is a solution of y = x+3. (2,5) (4,6) (5,8) (3,7)

MrRissso [65]

Answer:

(2,5) and (5,8)

Step-by-step explanation:

you can just plug in the numbers to get your answer and if two numbers aren't the same then its not a solution

example: (2,5)

5 = 2 + 3

5 = 5

5 does equal 5 making it a solution because it makes sense right?

example: (4,6)

6 = 4 + 3

6 = 7

this isn't a solution because six doesn't equal 7

URGENT<br>Which of the following is the graph of y=0.5sec (x+pi/3)-2?

arlik [135]

Answer:

See attachment.

Step-by-step explanation:

The given function is

$y=0.5\sec(x+\frac{\pi}{3})-2$

This is the graph of $y=\sec(x)$ that is shifted down 2 units and shifted to the left $\frac{\pi}{3}$ units.

When x=0, $y=0.5\sec(0+\frac{\pi}{3})-2$

$y=0.5\sec(\frac{\pi}{3})-2$

$y=1-2=-1$

The y-intercept is -1.

The correct choice is shown in the attachment
