Identify the variation as direct, inverse, joint or combined. V = r²h

Mathematics
1 answer:
trapecia [35]3 years ago
7 0

We are given equation V =  r²h.

Let us break it into parts to get the correct variation.

V = r²h could be written first V= r² × h.

And we could break it in two different proportions:

V ∝ r²  can be read as V is directly proportional to r².

V ∝ h  can be read as V is directly proportional to h .

Non of the variable r² or h in denominator.

<em>When we have any variable in denominator, it's an inverse variation and if we don't have any variable in denominator, it would be a direct variation.</em>

<h3>Therefore, we can say V = r²h is a direct variation.</h3>

Use the Remainder Theorem to find the remainder when P(x) = x^4 – 9x^3 – 5x^2 – 3x + 4 is divided by x + 3.
kirza4 [7]
P(x) = (x + 3)Q(x) + R 

<span> P(-3) = (0)Q(x) + R </span>

<span>i P(-3) = R </span>

<span>Now, P(-3) = (-3)⁴ - 9(-3)³ - 5(-3)² - 3(-3) + 4 
</span>So

<span>P(-3) = 81 + 243 - 45 + 9 + 4 </span>

Simultaneous equations <br>5x + 3y= 31<br>2x + y = 12 <br><br>a. find for x​<br>b. find for y
Anna007 [38]

Answer:

x=5

y=2

Step-by-step explanation:

5x + 3y= 31

-6x - 3y = -36  (multiple  by -3)

 

-x=-5

x=5

2(5)+y=12   or         25 + 3y= 31

10+y=12                  3y=6

y=2                          y=2

On a piece of graph paper, plot the following points: A (0, 0), B (5, 0), and C (2, 4). These coordinates will be the vertices o
shtirl [24]

The triangle is an isosceles triangle and the four triangles are similar

<h3>How to determine the triangle type?</h3>

The coordinates are given as:

A (0, 0), B (5, 0), and C (2, 4).

Calculate the distance between the coordinates using:

d = \sqrt{(x_2 -x_1)^2 +(y_2 -y_1)^2

So, we have:

AB = \sqrt{(0 -5)^2 +(0-0)^2} =5

AC = \sqrt{(0 -2)^2 +(0-4)^2} =4.5

BC = \sqrt{(5 -2)^2 +(0-4)^2} =5

The above shows that two sides are congruent.

Hence, the triangle is an isosceles triangle

<h3>The midpoints of the sides</h3>

This is calculated using:

(x, y) = 0.5 * (x1 + x2, y1 + y2)

So, we have:

AB = 0.5 * (0 + 5, 0 + 0) = (2.5, 0)

AC = 0.5 * (0 + 2, 0 + 4) = (1, 2)

BC = 0.5 * (5 + 2, 0 + 4) = (3.5, 2)

From the attached graph, we can see that the triangles are similar
