Answer:
-8/15
Step-by-step explanation:
So remember what sin, cos, and tan are.
sin = opposite/hypotenuse
cos = adjacent/hypotenuse
tan = opposite/adjacent
Now, using what we know of sin and cos, lets find opposite and adjacent to solve for tan.
Sin=-8/17
So this must mean that opposite is -8, and the hypotenuse is 17.
Next, lets find adjacent. Cos = 15/17
So this must mean that adjacent is 15, and again, hypotenuse is 17.
Now lets take the -8 of the opposite, and 15 of the adjacent, and get tan.
<u>Tan: -8/15. </u>
17 is not included in this whatsoever, since hypotenuse is not included in tan. And remember that it cannot be -15/8, since its opposite/adjacent, not adjacent/opposite.
Hope this helps!
Answer:B
Step-by-step explanation: a factor of a number that is multiplied by itself
Let m be the slope and b the y-intercept:
m=(y-y)/(x-x) and y=mx+b
Line A
y=4x-3.2
Line B
(3,0) and (0,6)
m= 6/-3= -2
y= -2x+b
0=-2(3)+b
b=6
y= -2x+6
Line C
(1.5,0) and (0,-6)
m=-6/-1.5=4
y=4x+b
0=4(1.5)+b
b = -6
y=4x-6
Line D
(-3,0) and (0,3)
m=3/3=1
y=x+b
0=-3+b
b=3
y=x+3
B is not a solution to the graph
