Answer:
Option (3)
Step-by-step explanation:
In a right triangle,
Cosine rule → 
Sine rule → 
In the given triangle,
By cosine rule,
Or cos(h°) = z ÷ x
Therefore, Option (3) will be the answer.
Answer:
m=-11
point-slope form _y-y1=m(x-x1)
so 5 , 2 is x1,y1
so y-2=-11(x-5)
Answer:
Step-by-step explanation:
The only place that the function is increasing is [-3, -1] (learn your interval notation). At x = -3, y = -11; at x = -2, y = -6 (-6 is greater than -11); and at x = -1, y = -1 (-1 is greater than -6). The next x value, 0, returns a y value of -2. But -2 is less than -1, the value before it, so it begins deceasing again at x = 0.
A1 There are two ends so their combined surface area is 2 π * r2. The surface area of the side is the circumference times the height or 2 π * r * h, where r is the radius and h is the height of the side. The entire formula for the surface area of a cylinder is 2 π r2 + 2 π r h. so add the number of the height and radius plug in and you will get the answer for that.
