Answer:

D. Obtuse Scalene

Step-by-step explanation:

One of the angles is over 90 degrees, which classifies the triangle as obtuse (right triangles are 90 degrees, and acute triangles are under 90 degrees). None of the side lengths are equivalent, so therefore the triangle is scalene (Isosceles triangles have two sides that are the same length). Hope this helps.

What is the equation of the plane that contains the triangle shown in the diagram *answers in question*

LiRa [457]

Answer:

Option C is correct.

$10x+4y+5z =20$

Step-by-step explanation:

The intercept form of the equation of plane is given by:

$\frac{x}{a}+\frac{y}{b} +\frac{z}{c} = 1$ .....[1]

where

a is the intercept of x-axes

b is the intercept of y-axes and

c is the intercept of z-axes

From the given diagram:

a = 2

b = 5

c = 4

Substitute these in equation [1] we have;

$\frac{x}{2}+\frac{y}{5} +\frac{z}{4} = 1$

LCM of 2, 5 and 4 is 20

$\frac{10x+4y+5z}{20} = 1$

Multiply equation 20 both sides we get;

$10x+4y+5z =20$

Therefore, the equation of plane that contains the given triangle is, $10x+4y+5z =20$

Usimov [2.4K]

Answer:

Edge length in inches = 3√(v in³)

Step-by-step explanation:

A jewelry box is shaped like a cube, with it's volume as v cubic inches.

The formula for the volume of a cube = (edge length)³

From the question, we are asked to write an expression that represents the edge length of julies jelwery box in inches

volume of a cube = (edge length)³

v in³ = edge length ³

We cube root both side

= 3√(v in³) = 3√(edge length³)

Edge length = 3√(v in³)

Therefore, the expression that represents the edge length of julies jelwery box in inches is:

Edge length in inches = 3√(v in³)

line passes through the point (0, –1) and has a positive slope. Which of these points could that line pass through? Check all th

sammy [17]

Answer:

Points passing though are (12, 3),(–2, –5) and (1, 15)

Step-by-step explanation:

For a line passing through (x₁,y₁) and (x₂,y₂) slope is given by $\frac{y_2-y_1}{x_2-x_1}$ .

Here we have one point (0, –1), we need to check slope of all the points given.

(12, 3)

$m=\frac{3-(-1))}{12-0}=\frac{1}{4}>0$

(–2, –5)

$m=\frac{-5-(-1))}{-2-0}=\frac{-4}{-2}=2>0$

(–3, 1)

$m=\frac{1-(-1))}{-3-0}=\frac{2}{-3}=-\frac{2}{3}$

(1, 15)

$m=\frac{15-(-1))}{1-0}=\frac{16}{1}=16>0$

(5, –2)

$m=\frac{-2-(-1))}{5-0}=\frac{-1}{5}=-\frac{1}{5}$

Points with positive slope are (12, 3),(–2, –5) and (1, 15)
