Which graph represents the solution set to the system of inequalities?
1 answer:
Answer:
The answer to your question is: The forth one is the right option
Step-by-step explanation:
Graph each of the inequalities
a) y - 6 ≤ 0 but y = 6 find this line in the graph and all the points below it are shaded. It's not a dotted line
b) y < 1/3 x + 4 but y = 1/3x + 4 It's a dotted line with intercepts (0.4) and ( 12,0), and only need the points below this line
c) y + 6 > -3x but y = -3x - 6 It's a dotted line with intercepts (0,-6) and (-2,0), and we need the points up the line

There are a couple of ways to tackle this one, using the 45-45-90 rule or just using the pythagorean theore, let's use the pythagorean theorem.
the angle at A is 45°, and its opposite side is BC, the angle at C is 45° as well, and its opposite side is AB, well, the angles are the same, thus BC = AB.
hmmm le'ts call hmmm ohh hmmm say z, thus BC = AB = z.

Answer:
942
Step-by-step explanation :
so your d is 300 so your r = 300/2= 150
a=3.14*r*r= 3.14*150*150= 70650
c= 3.14*d= 3.14*300= 942

The curved surface area of solid cylinder is
As we are given that:
Diameter of solid cylinder = 8 cm
Length or Height o solid cylinder = 140 cm
Formula used to calculate the curved surface area of cylinder is:2n x h
Curved surface area of cylinder =2r x h
where,
r = radius of cylinder
h = height or length of cylinder
Radius of cylinder = daimeter
Now putting all the given values in above formula, we get:
Curved surface area of cylinder = 2x 22/7 x 140cm
Curved surface area of cylinder =
Therefore, the curved surface area of solid cylinder is3520cm^{2}
