Answer:
B
Step-by-step explanation:
Since the triangle is right use the sine/ tangent ratios to solve for x and y
note sin60° = 
and tan60° = 
sin60° = 
= 
ysin60° = 3
y × = 3
multiply both sides by 2 and divide by
y v= 6
= 6
tan60° = 
= 
xtan60° = 3
x × = 3
divide both sides by
x = 3 = 3
The equation of the tangent line can be found using slope formula and fact that slope = dy/dx.
where (x0,y0) is point A ---> (0,-1)
Then rearrange equation into slope-intercept form:
Finally sub in x=0 into dy/dx to get slope at the point (0,-1)
Answer:
Nope!
Step-by-step explanation:
No, because 9 x 4 = 36, whereas 11 x 3 = 33.
