Point slope graph y+2÷4(x+5)
ladessa [460]

Answer:

See attachment for graph

Or

The slope intercept form is y=4x+18

Step-by-step explanation:

Assuming you want to graph the straight line given in point-slope form as

y+2=4(x+5)

Then we need at least two points on this line

When we compare to the point-slope formula y-y_1=m(x-x_1) then we  obtain (-5,-2) as a point on this line so we plot it.

When x=0, y=4(0+5)-2=18 so we plot (0,18)

We then draw a straight line through as shown in the attachment.

On the other hand, if you had wanted the equation slope intercept form, then we expand to obtain:

y+2=4x+20

\implies y=4x+20-2

\implies y=4x+18

whats the lateral area of a right circular cone if the diameter of the base is 4m and the slant height of the cone is 15m? round
alex41 [277]
First is to understand the terms. Lateral area is the surface area of a 3D figure, excluding the area of any base. 
<span>Laterial Area (L.A.) of a right cone = pi*radius*slant height </span>
<span>radius = 1/2 * diameter </span>
<span>L.A. = pi*(1/2)*(4)*(15)=30*pi </span>

<span>the formula for this is pi*r*rt(r^2 + h^2). If the diameter is 4, then the radius is 2. If the slant height is 15, then to get the real height we use the Pythagorean Theorem and get rt(221). So the lateral area is pi*2*rt(2^2 + (rt221)^2)...= 2pi*rt(225) = 30pi = 94.248 meters squared which is rounded to 94 meters squared.</span>
