Factoring x2-14x+11
The first term is, x2 its coefficient is 1 .
The middle term is, -14x its coefficient is -14 .
The last term, "the constant", is +11
Step-1 : Multiply the coefficient of the first term by the constant 1 • 11 = 11
Step-2 : Find two factors of 11 whose sum equals the coefficient of the middle term, which is -14 .
-11 + -1 = -12 -1 + -11 = -12 1 + 11 = 12 11 + 1 = 12
Observation : No two such factors can be found
Hey there! :)
Answer:
y + 32 = 3(x + 8)
Step-by-step explanation:
Begin by finding the slope of the line using the slope formula:
Plug in the coordinates of the points into the equation:
Simplify:
m = 3.
Point-slope form is:
y-y₁=m(x-x₁)
Plug in the coordinates of the first point, as well as the slope:
y - (-32) = 3(x - (-8)
y + 32 = 3(x + 8)
Break up the problem into two parts: 1) find the surface area of the sides of the cylinder and 2) find the surface area of the top or bottom and multiply your result by 2.
Part 1: Imagine that you cut the side of the cylinder parallel to its axis once and then open up this shape to form a rectangle. The length of this rectangle is equal to the circumference of the cylinder times the height/length of the cylinder parallel to its axis: A1 = 2 pi (7 units) (3 units), or 42 pi square units.
Part 2: The total area of the two ends of the cylinder is 2 (pi [7 units]^2), or 98 pi square units.
Add these two areas together to get the total surface area of the cylinder.
