Represent geometrically the following numbers on the number line: √4.5 √8.3. (step by step explanation preferably done in notebook please) I’ll mark the best answer as brainliest
Answers
Answer:
To represent geometrically √x on a number line:
Draw a line segment AB with length x (where point A is -x and point B is zero on the number line).Extend AB by drawing a line segment BC of length 1 unit.Draw a line perpendicular to AC at point B.Let O be the midpoint of AC.Draw a semicircle with center O and radius OA.Let point D be where the semicircle intersects with the perpendicular line. BD = √xDraw an arc with center B and radius BD from point D to the number line.BE = √x ⇒ point E = √x on the number line.Attachment 1
To represent geometrically √4.5 on a number line:
Draw:
Point A = -4.5Point B = 0Point C = 1Draw a line perpendicular to AC at point B.
Let O be the midpoint of AC:
[tex]\implies \sf O=\dfrac{-4.5+1}{2}=-1.75[/tex]
Draw a semicircle with center O and radius OA
[tex]\implies \sf OA=\dfrac{AC}{2}=\dfrac{5.5}{2}=2.75[/tex]
Let point D be where the semicircle intersects with the perpendicular line
[tex]\implies \sf BD=\sqrt{AB}=\sqrt{4.5}[/tex]
Draw an arc with center B and radius BD from point D to the number line.
[tex]\implies \sf BE=\sqrt{4.5}[/tex]
⇒ Point E is [tex]\sf \sqrt{4.5}[/tex] on the number line.
Attachment 2To represent geometrically √8.3 on a number line:
Draw:
Point A = -8.3Point B = 0Point C = 1Draw a line perpendicular to AC at point B.
Let O be the midpoint of AC:
[tex]\implies \sf O=\dfrac{-8.3+1}{2}=-3.65[/tex]
Draw a semicircle with center O and radius OA
[tex]\implies \sf OA=\dfrac{AC}{2}=\dfrac{9.3}{2}=4.65[/tex]
Let point D be where the semicircle intersects with the perpendicular line
[tex]\implies \sf BD=\sqrt{AB}=\sqrt{8.3}[/tex]
Draw an arc with center B and radius BD from point D to the number line.
[tex]\implies \sf BE=\sqrt{8.3}[/tex]
⇒ Point E is [tex]\sf \sqrt{8.3}[/tex] on the number line.

4n^2-15n-25 factor trinomials pls help me on this i would love if you would put the steps too thank you
Answers
---Multiply a x c
Quadratic Form: ax^2 + bx + c
4 x -25 = -100
---Find a factor pair of -100 that adds up to -15
-20 x 5 = - 100
-20 + 5 = -15
---Separate the b term into your two factors
4n^2 + 5n - 20n - 25
This can take some trial and error (though there are only two options) because when you factor, you want the inside of the parentheses to be the same. If you look at the next step, (4n + 5) appears twice.
---Factor each binomial
n(4n + 5) - 5 (4n + 5)
---Rewrite
(n - 5)(4n + 5)
What you're really doing here is factoring out the (4n + 5), which leaves you with the terms that you factored out in the previous step. You then combine these terms into one set of parenthesis.
Answer: (n - 5)(4n + 5)

The taylor series about x=5 for a certain function converges
Answers
The evaluation of the function [tex]f(x)=e^x[/tex] at a=0 and x=5 by the taylor series will have a value 65.37.
What is taylor's series?We know the fromula of taylor series is given as:
[tex]f(x)=f(a)+\dfrac{f'((a)}{1!}(x-a)+\dfrac{f''(a)}{2!}(x-a)^2+\dfrac{f'''(a)}{3!}(x-a)^3.................[/tex]
Now for the function [tex]f(x)=e^x[/tex] the taylor's series will become.
[tex]f(x)=e^a+e^ax+\dfrac{e^ax^2}{2!}+\dfrac{e^ax^3}{3!}+\dfrac{e^ax^4}{4!}[/tex]
[tex]f(x)=1+x+\dfrac{x^2}{2!}+\dfrac{x^3}{3!}+\dfrac{x^4}{4!}[/tex]
So at x=5 the values will become
[tex]f(x)=1+5+12.5+20.83+26.04=65.37[/tex]
hence the evaluation of the function [tex]f(x)=e^x[/tex] at a=0 and x=5 by the taylor series will have a value 65.37.

A triangle has a base that is 19 inches long, and a height of 12 inches. What is the area of the triangle?
Answers
Answer:
[tex]144[/tex] [tex]inches^2[/tex]
Step-by-step explanation:
Hey there!
In order to find the area of a triangle, you need to:
Multplipy the base by the height
Then you take that product and multiply it by 1/2 (basically divide it by 2)
Then you get your area!
Base: 19
Height: 12
19 x 12
228
228 x 1/2
228/2
114
So the area of this triangle is [tex]144[/tex] [tex]inches^2[/tex]

the perimeter of an equilateral triangle is 6cm find its area
Answers
Answer:
√3 cm
or
1.73 cm to the nearest hundredth.
Step-by-step explanation:
Each side must be 2 cm long
Using Heron's formula
Area = √(s(s-a)(s-b)(s-c) where s = semi-perimeter, a , b and c are the 3 side lengths.
So here s = 6/2 = 3 and all the sides = 2 so
Area = √(3(3-2)^3
= √3 cm.
the area of the triangle below is 29.25 square centimeters the height is 6.5. what is the length of the base?

Answer: 9
Step-by-step explanation:
½bh = 29.25
½ × 6.5 × b = 29.25
B= 29.25/ 3.25
The length of the base of the triangle is 9 centimeters.
What is the base length of the triangle?The area of a triangle is simply expressed as half base multiplied by height.
Area A = 1/2 × base length × height
Given the dimensions of the triangle:
Area A = 29.25 square centimeters
Height = 6.5 centimeters
Base length =?
To find the height of the triangle, plug the given values into the above formula and solve for h:
Area A = 1/2 × base length × height
29.25 = 1/2 × base length × 6.5
29.25 = base length × 3.25
Base length = 29.25 / 3.25
Base length = 9 cm.
Therefore, the base length measures 9 centimeters.

How to find the density and volume?She is serving hot coffee and cold coffee in two rectangular-shaped tanks, each with dimensions width of 8.75 inches, a length of 8.75 inches, and a height of 23 inches.
The hot coffee has a density of 5.8 oz/in³ and the cold coffee has a density of 3.5 oz/ in³.
Then the volume of the coffee in each tank will be
We know that the dimension of both tanks is equal. Then the volume will remains equal.
Volume = L × B × H
Volume = 8.75 × 8.75 × 23
Volume = 1760.9375 ≅ 1760.94 in³
Then the mass of the coffee in each the tank will be
The mass of hot coffee will be
Mass = Density × Volume
Mass = 5.8 × 1760.94
Mass = 10213.45 oz
The mass of cold coffee will be
Mass = Density × Volume
Mass = 3.5 × 1760.94
Mass = 6163.29 oz
Then the number of the tank placed on a table is one only.
