Write the equations of the line that passes through the point 4,3) and is perpendicular to the line y=2x−4 . Write the equation

Anon25 [30]

Answer:

Step-by-step explanation:

The product of slopes of perpendicular lines is -1

y = 2x − 4 ⇒ m₁ = 2

m₁m₂ = -1

2m₂ = -1

m₂ = -¹/₂

The Point-Slope form of equation of a line with slope of "m" and passing through point (x₁, y₁) is: y - y₁ = m(x - x₁)

m = -¹/₂

(4, 3) ⇒ x₁ = 4, y₁ = 3

So the equation in point-slope form:

y - 3 = -¹/₂(x - 4)

Therefore:

y - 3 = -¹/₂x + 2

y = -¹/₂x + 2 + 3

What is the area of the two-dimensional cross section that is parallel to face ABC ?

Umnica [9.8K]

Answer:

The area of the two-dimensional cross section is $30\ ft^{2}$

Step-by-step explanation:

we know that

The two-dimensional cross section that is parallel to face ABC is a triangle congruent with the triangle ABC

Therefore

Calculate the area of triangle ABC

$A=\frac{1}{2}(BC)(AB)$

we have that

Triangles ABC and DEF are congruent

$BC=EF=12\ ft$

$AB=5\ ft$

substitute

$A=\frac{1}{2}(12)(5)=30\ ft^{2}$
