For a right triangle, we have he advantage of using the trigonometric functions like cosine and sine.
If you use cosine function:
cos45 = adjacent/hypotenuse
cos 45 = b/c
c = b/cos 45
If you use sine function:
sin 45 = opposite/hypotenuse
sin 45 = a/c
c = a/sin45
From the choices, the answer is <span>b over cos 45 degrees</span>
first find the slope
m = (y2-y1)/(x2-x1)
choose any 2 points
m= (17 - 5)/( 2 + 2)
m = 12/4
m = 3
the difference between 5 and 9 is 4
do 4 x 3 = 12
then 26 + 12 = 38
answer (9,38)
Answer:
14 minutes...
Step-by-step explanation:
Wage for an hour: $11.50 per hour
Wage for first 35 hours: $11.50*35 = 402.5
Wage after 35 hours: $17.25 per hour
Earning in one week: $626.75
Therefore, hours worked :
$626.75 - 402.5 = 224.25
Now 224.25/17.25 = 13
Therefore total hours is
13+35 = 48 Hours

The rate of change is 3/4.
Explanation:
The rise is 3 and the run is 4.
The slope, or rate of change, is rise/run.
Answer:
Step-by-step explanation:
- In order to combine these two equations, an idea you need to keep in mind is finding a way of setting these equations as equal to each other. I saw that each equation shared a common value, . In this case, we need to isolate in the first equation so that both equations .
- With this, we now know that both and are equal to , so we can set them equal to each other.
- Reply to this if anything I'm saying or doing is confusing in any way, or if you find a mistake. :) Solve for .
- Hopefully this answer is correct AND makes sense in terms of how I achieved it. Again, reply to this with any questions or mistakes I made and I'll do my best to answer or fix them.
