Answer:

Inverse variation k=4

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

In this problem

The graph represent a inverse variation

Because

if x increases ----> y decreases

if x decreases ----> y increases

Find the value of k

we have that

For x=2, y=2 -----> see the graph

$k=y*x$

substitute

$k=2*2=4$

tiny-mole [99]

Answer:

A(an) altitude of a prism is a perpendicular segment that joins the planes of the bases. (The height h is the length of one.)

Step-by-step explanation:

AN ALTITUDE - An altitude of a triangle is a line segment that passes through a vertex and is perpendicular to (i.e. forms a right angle with) the base line (the side opposite the vertex). The expanded base of the altitude is the line that contains the opposing side. The foot of the altitude is the point where the extended base meets the altitude. The area of a triangle can be calculated using altitudes: one half of the product of an altitude's length and its base's length equals the triangle's area. As a result, the longest altitude is perpendicular to the triangle's shortest side. Through trigonometric functions, the heights are also connected to the triangle's sides.

Hence , the answer is an altitude .

Given: ABCD is a parellelogram. Prove: AB=CD and BC=DA

ozzi

Answer:

Step-by-step explanation:

We have given a parallelogram ABCD.

For a parallelogram,

Opposite pair of sides are parallel to each other.

i.e AD is parallel to BC and AB is parallel to CD.

From the attached figure,

∡1 = ∡4 and ∡2 = ∡3 {If two parallel lines cut by a transversal line then alternate interior angles are congruent }

Next, AC ≅ AC {Reflexive identity}

hence, ΔABC ≅ ΔCDA , By Angle-Side-Angle(ASA) congruent property of triangle.

Therefore, AB = CD and AD = BC {Proved}
