Write an equation of the line that passes through (5, −1) and is perpendicular to the line y=12x−1.

Lisa [10]

Step-by-step explanation:

solution

let,A(5,-1)

given

y=12x-1

or, y = 12 × x + (-1)

comparing it with y=mx+c

we get

x=1

y = c = -1

now

A(5,-1) and B(1,-1)

equation of line is,

(y-y1)/(x-x1) = (y2-y1)/(x2-x1)

or, (y+1)/(x-5) = (-1+1)/(1-5)

or, (y+1)/(x-5) = 0/-4

cross multiply

-4y-4 = 0

or, 0=4y+4

or, 4y+4=0 is the required eqn

I think this is the process and answer too.

I hope this helps you

What is the volume of the following triangular pyramid?

Readme [11.4K]

Answer:

The volume of the triangular pyramid

V = 566.66 in³

Step-by-step explanation:

Step(i):-

The volume of the triangular pyramid

$= \frac{1}{3} X base area X height$

Base area = Area of the triangle

$A= \frac{1}{2} X base X height$

Given the base of the triangle (b) = 17in

Given Height of the triangle (h ) =10 in

$A= \frac{1}{2}( 17 ) (10) = 85$

The base area of the pyramid ( A) = 85 in²

Step(ii):-

Given the height of the pyramid (h) = 20in

The volume of the triangular pyramid

$= \frac{1}{3} X base area X height$

The volume of the triangular pyramid

= $= \frac{1}{3}( 85)(20) = 566.66$

Final answer:-

The volume of the triangular pyramid

V = 566.66 in³

What is f(x) = 8x2 + 4x written in vertex form?

lesya [120]

The equation is a quadratic equation, and it represents a parabola, opening upward. The standard form of this parabola is (x – h)^2 = 4a (y – k) f(x) = y = 8( x^2 + (1/2)x) y + ½ = 8( x^2 + (1/2)x + 1/16) (1/8)(y + ½) = (x + ¼)^2 Vertex is at (-1/4, -1/2)
