How to solve pythagorean theorem i need an assay someone help

Veronika [31]

Answer:

first write the formula

Step-by-step explanation:

Hypotenuse^2 = Perpendicular ^2 + Base^2

only applicable for a right triangle (one of the sides is of measure 90 degree

Give an example

let is assume in Triangle ABC, angle B = 90 degrees

AB = 3cm

BC = 4 cm

to find AC or hypotenuse

Solution

by using pythagoras formula we get

(AB)^2 + (BC)^2 = (AC)^2

(3)^2 + (4)^2 = (AC) ^2

9 + 16 = (AC)^2

25 = (AC)^2

Root of 25 = AC

5cm =AC

Name the equation for any horizontal line of your choosing

Lerok [7]

Answer:

y=0 (x-axis itself)

Step-by-step explanation:

A horizontal line is a line which is parallel to x-axis

It has a slope of 0

Any line whose slope is m can be represented as

y = mx + c

Here m=0

y=c where c is a constant

Any line whose equation is of the above form is a horizontal line.

The rectangle below has an area of x^2+8x+15x

Darina [25.2K]

Answer:

The length of the rectangle is x+5.

Step-by-step explanation:

Given : The rectangle below has an area of $x^2+8x+15$ square meter and a width of $x+3$ meter.

To find : What expression represents the length of the rectangle?

Solution :

The area of the rectangle is given by,

$\text{Area}=\text{Length}\times \text{Breadth}$

$\text{Area}=x^2+8x+15$

$\text{Breadth}=x+3$

$x^2+8x+15=\text{Length}\times(x+3)$

$\text{Length}=\frac{x^2+8x+15}{x+3}$

$\text{Length}=\frac{(x+5)(x+3)}{x+3}$

$\text{Length}=x+5$

Therefore, the length of the rectangle is x+5.

Two life insurance companies determine their premiums using different formulas:

Pie

Answer:

<em>The age at which both companies charge the same premium is 44 years</em>

Step-by-step explanation:

<u>Graph Solution to System of Equations</u>

One approach to solving systems of equations of two variables is the graph method.

Both equations are plotted in the same grid and we find the intersection point(s) of both graphs. Those are the feasible solutions.

The annual premium p as a function of the client's age a for two companies are given as:

Company A: p= 2a+24

Company B: p= 2.25a+13

The graphs of both functions are shown in the image below.

The red line indicates the formula for Company A and the blue line indicates the formula for Company B.

It can be seen that both lines intersect in the point with approximate coordinates of (44,112).

The age at which both companies charge the same premium is 44 years
