There is a rather-hard-to-remember formula for the lateral area of a cone. I'd suggest you look that up on the 'net. Here you have a right circular cone with radius 24/2, or 12 units and slant height 36 units. If you're unable to find the formula on your own, come back and I'll give you some hints.

when a ladder is rested against a tree, the foot of the ladder is 1 m from the base of the tree and forms an angle of 64° with t

Pie

Answer:

2.05 meters

Step-by-step explanation:

Superimpose a triangle when drawing out the situation. The distance the ladder reaches up the tree is the side of the triangle opposite of the angle. The distance the ladder is from the tree is side adjacent to the triangle. We can use tangent to solve this.

Tan X = (opposite side)/(adjacent side)

Tan 64 = a/1

Tan 64 = a (anything over 1 is just itself)

2.050303842 = a (use tan on your calculator)

Write an equation in slope Intercept form for the line with slope

aivan3 [116]

Answer:

y= $\frac{2}{5}$ x -3

Step-by-step explanation:

slope-intercept form is y=mx+b

m= slope

b= y-intercept

so plugin your numbers with the given data...

and you get y=2/5x-3

For the graph, you start at -3 on the y-intercept and then move right 5 and up 2

Graph is the picture below :)

Answer:

If you aren't looking for the quadratic solving method then comment it down below and tell me what you're looking for

QUADRATIC EQUATION

x²- 4x = 6

(x - 2)²- 4 = 6

(x - 2)² = 10

x - 2 = ±10

x = ±10+2

x = -8, 12
