I REALLY NEED HELP PLEASE

Mathematics
1 answer:

Answer:

sin X =  12/13

cos X = 5/13

tan X = 12/5

Step-by-step explanation:

Recall the definitions as follows:

For a right triangle (i.e one angle is 90 deg) with one of the angles X

sin X = opposite side / hypotenuse

cos X = adjacent side / hypotenuse

tan X = opposite side / adjacent side

In our case for angle A, the following applies:

opposite = 36

adjacent = 15

hypotenuse = 39

hence

sin X = opposite side / hypotenuse = 36/39 = 12/13

cos X = adjacent side / hypotenuse = 15/39 = 5/13

tan X = opposite side / adjacent side = 36 /15 = 12/5

Write a linear function f with the values f (-1) = 5 and f (3) = 4.<br> A function is f(x) =
Drupady [299]

Answer:

Step-by-step explanation:

Since we have points (-1,5) and (3,4) we can find the slope m of y=mx+b

m=(y2-y1)/(x2-d1)=(5-4)/(-1-3)=1/-4=-1/4 so we have

y=-x/4+b, using point (3,4) we can solve for the y intercept, b.

4=-3/4+b, b=19/4, so the line is

y=(-x+19)/4
