Given ABC with A(0, 0), B(2, 3),
and C(4,0), prove ABC is isosceles
Step-by-step explanation:
1. if to calculate the length of AB; AC and BC, then:
[tex]|AB|=\sqrt{(2-0)^2+(3-0)^2} =\sqrt{13}.[/tex]
[tex]|AC|=\sqrt{(4-0)^2+(0-0)^2} =4.[/tex]
[tex]|BC|=\sqrt{(2-4)^2+(0-3)^2}= \sqrt{13}.[/tex]
2. if to compare the calculated lengths, then:
AB=BC. It means the given triangle is isosceles.

find the length of side VW
Answer:
46 units.
Step-by-step explanation:
To find the perimeter, you need to add up all the sides. Knowing this, we can set up an equation to solve for y.
2(5y + 1) + 2(4y + 3) = 170
10y + 2 + 8y + 6 = 170
18y + 8 = 170
18y = 162
y = 9
Now that we know y = 9, we can solve for vw.
vw = 5(9) + 1
vw = 45 + 1
vw = 46
Therefore, line vw is 46 units.
Answer: VW=11
4y+3=5y+1
2=y

The straight line L, has equation y = 3X - 4.
The straight line L2, is perpendicular to L, and passes through the point (9, 5). Find an equation of line L2. Show your working out.
Step-by-step explanation:
y = mx + c, where m is the slope of the line and c is the y-intercept.
We have y = 3x - 4 as line L.
Slope of line L = 3
=> Slope of line L2 = -1/3
We have y = -1/3 x + c as our line L2 equation.
When x = 9, y = 5.
=> (5) = -1/3 * (9) + c
=> 5 = c - 3, c = 8
Hence the answer is y = -1/3 x + 8.
The equation of required line [tex]l_2[/tex] is .
Y = mX+c
[tex]Y = \frac{-1}{3} x + 2[/tex]
Given, The equation of straight line L.
Y=3X-4
compareing with the standard equation of line
Y=mX+c
slope of the equation of line L is [tex]m_1[/tex]= 3.
The product of slopes of two perpendicular lines is -1.
[tex]\rm m_1. m_2 = -1[/tex]
[tex]3.m_2 = -1\\m_2 = \frac{-1}{3}[/tex]
The slope of perpendicular line is and it passes through the point (9,5). So the equation of the line is
[tex]y = m_2x+c[/tex]
[tex]5 = -\frac{1}{3} . 9 + c[/tex]
5 = -3 + c
5+3 = c
c = 8
Therefore, the equation of required line [tex]l_2[/tex] is .
Y = mX+c
Y = [tex]\frac{-1}{3} X +8[/tex]

Find the percent increase from 15 to 18
Answer:
The percentage increase would be 20%
Step-by-step explanation:
worked it out
The percent increase from 15 to 18 is 20%.
To find the percent increase from 15 to 18, we can use the following formula Subtract the initial value from the final value, then divide the result by the absolute value of the initial value.
Percent Increase = (New Value - Old Value) / Old Value * 100
Using this formula, let's calculate the percent increase:
Percent Increase = (18 - 15) / 15 * 100
Percent Increase = 3 / 15 * 100
Percent Increase = 0.2 * 100
Percent Increase = 20
Therefore, the percent increase from 15 to 18 is 20%.

Determine the dimensions of a rectangular solid (with a square base) with maximum volume if its surface area is 529 square meters. Round each dimension to 4 decimal places
Answer:
[tex]x=23/\sqrt{6}[/tex],
[tex]y= \frac{23}{6\sqrt{6}}[/tex]
Step-by-step explanation:
From the question we are told that
Surface area is 529 square meters
Generally the dimensions of the cuboid
[tex]v=x^y[/tex]
[tex]D=4xy+2x^2 =529[/tex]
[tex]V=x^29(\frac{529-6x^2}{4x})[/tex]
[tex]V' =529-6x^2/4[/tex]
[tex]v'=0[/tex]
Therefore
[tex]529=6x^2[/tex]
[tex]x=\sqrt{\frac{529}{6} }[/tex]
[tex]x=23/\sqrt{6}[/tex]
Mathematically
[tex]v''=\frac{12x}{4}[/tex]
[tex]v''=-3\frac{23}{\sqrt{6} }<0[/tex]
[tex]y= \frac{529-2*(\frac{529}{6} }{4*\frac{23}{\sqrt{6} } }[/tex]
[tex]y= \frac{23}{6\sqrt{6}}[/tex]
Therefore
[tex]x=23/\sqrt{6}[/tex]
and
[tex]y= \frac{23}{6\sqrt{6}}[/tex]

What is the end behavior of the graph of f(x) = -0.25x2 – 2x + 1?
End behavior means what are the y-values doing as the x-values both increase and decrease without bound.
This is a parabola (degree 2) with a negative leading coefficient (−0.25). Therefore both ends of the graph will be going towards negative infinity.
As x increases, f(x) decreases.
As x decreases, f(x) decreases.
Since the highest degree of the given function, f(x) = -0.25x² – 2x + 1 the end behavior of the graph will be down.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that,
f(x) = -0.25x² – 2x + 1
A polynomial function's end behavior defines how the graph acts as x gets closer. The leading term of the function—that is, the term with the highest n-value for a × n, where n is a positive integer and an is any nonzero number—allows us to infer the function's final behavior.
The highest degree of the given function is 2. When the function is plotted on the graph we get the graph shows downward behavior when x gets closer.
Thus, since the highest degree of the given function, f(x) = -0.25x² – 2x + 1 the end behavior of the graph will be down.

A hot air balloon is rising vertically. From a point on level ground 110 feet from the point directly under the passenger compartment, the angle of elevation to the balloon changes from 25 degrees to 32 degrees. How far, the nearest tenth, does the balloon rise during this period
Answer:
17.44 ft.
Step-by-step explanation:
Given,
The Distance of the hot air balloon: 110 ft
Change in elevation, [tex]\theta_1 = 25^0, \theta_2 = 32[/tex]
We know that,
[tex]\tan \theta = \dfrac{Perpendicular}{base}[/tex]
Now,
[tex]\tan \theta_1 = \dfrac{h_1}{110}[/tex]
[tex]\tan 25^0= \dfrac{h_1}{110}[/tex]
[tex]h_1 = 51.294\ ft[/tex]
[tex]\tan \theta_2= \dfrac{h_2}{110}[/tex]
[tex]\tan 32^0= \dfrac{h_2}{110}[/tex]
[tex]h_2 = 68.736\ ft[/tex]
Rise of balloon = 68.736 - 51.294
= 17.442 ft
= 17.44 ft
Hence, the rise of the balloon rise is 17.44 ft.

Answer:
The answer is 630 miles using a 30 gallons tank.
Step-by-step explanation:
Well this question is incomplete, but if we are trying to find how many miles can 30 gallons give then the answer would be 630.
Why? Well since 21 miles = 1 gallon then 630 miles = 30 gallons.
Because 21 multiplied by 30 = 630.

Value of x in the equation 2(x+3)=4(x-1)?
Answer:
x = 5
Step-by-step explanation:
In this question, you would solve for x.
Solve:
2(x + 3) = 4(x - 1)
Use the distributive property.
2x + 6 = 4x - 4
Subtract 4x from both sides.
-2x + 6 = -4
Subtract 6 from both sides.
-2x = -10
Divide both sides by -2
x = 5
The value of x is 5.
