The rangers at two park stations spot a signal flare at the same time. Based on the measurements shown in the diagram, what is the distance between park station 1 and the point where the flare was set off? Round to the nearest tenth.
The distance between park station 1 and the point where the flare was set off is 73.9 km.
What is distance?Distance is the length between two points expressed in meters or kilometers.
To calculate the distance between park station 1 and the point where the flare was set off can be calculated using Sine Rule
Formula:
a/sinA = b/sinB....................... Equation 1Where:
a = Distance between park station 1 and the point where the flare was set off.Make a the subject of the equation
a = bsinA/sinB............ Equation 2From the diagram,
Given:
A = 59°B = (180-59-75) = 46°b = 6.2 kmSubstitute these values into equation 2
a = 6.2(sin59°)/(sin46°)a = 73.9 kmHence, the distance between park station 1 and the point where the flare was set off is 73.9 km.

The volume of the coffee in each tank will be 1760. in³. The mass of cold coffee and hot coffee will be 6163.29 oz and 10213.45 oz. Then the number of the tank placed on a table is one only.
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.

Use Parts I and II to determine if AB and CD are parallel, perpendicular, or neither. Explain your answer.
Graph and on the grid to support your answer from Part III.
Answer:
The slopes of parallel lines are the same
The slopes of perpendicular lines are negative reciprocals
Line AB
[tex]\textsf{let}\:(x_1,y_1)=(3,4)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(7,7)[/tex]
[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{7-4}{7-3}=\dfrac{3}{4}[/tex]
Line CD
[tex]\textsf{let}\:(x_1,y_1)=(0,0)[/tex]
[tex]\textsf{let}\:(x_2,y_2)=(-6,8)[/tex]
[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{8-0}{-6-0}=-\dfrac{4}{3}[/tex]
As the slopes of AB and CD are negative reciprocals of each other, lines AB and CD are perpendicular.
the perimeter of an equilateral triangle is 6cm find its area
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.

4n^2-15n-25 factor trinomials pls help me on this i would love if you would put the steps too thank you
---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
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?
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]
