The slope of a line perpendicular to line E is -(5/3).
How do you calculate slope of a perpendicular line?By taking the negative reciprocal of the slope of the provided line, one can determine the slope of a perpendicular line from that line. We obtain m₂ = -1/m₁ if the slope of the provided line is m₁ and the slope of a perpendicular line is m₂.Given:
Line E passes through the points (-3, 4) and (2, 7).
Slope of line E = [tex]\frac{y_{2}-x_{1} }{x_{2}-x_{1} }[/tex]
= [tex]\frac{7-4}{2-(-3)}[/tex]
= [tex]\frac{3}{5}[/tex]
So, the slope of a line perpendicular to line E will be the negative reciprocal of the slope of line E i.e. -(5/3).
Therefore, the slope of a line perpendicular to line E is -(5/3).

The four algebra classes at sanchez school are going on a field trip to a museum. each class contains s students. the museum charges $8 per student for admission. there is also a flat fee of $200 for the buses. a. write an expression for the total cost of the buses and the museum admission fees for all four classes. b. write a rational expression for the cost per student. simplify the expression as much as possible. c. use the expression you wrote in part (b) to find the cost per student if each class has 20 students.
a)The expression for the total cost for all four classes can be given as 32s + 200. b) the rational expression for the cost per student is 2(4s+25)/s c) if each class has 20 students then the cost per student is equal to $10.50.
a) Total cost expression can be determined as follows:
total fees of admission + fees of bus = total cost
total cost = (4s × 8) + 200
total cost = 32s + 200
b) A rational expression to determine the cost per student can be calculated as follows:
cost per student = total cost ÷ the total number of students
cost per student = 32s + 200 ÷ 4s
We now factor the numerator by using its GCF;
cost per student = 4 × 2 (4s + 25) / 4×s
cost per student =2 (4s + 25) / s
c) Now using this expression we can find the cost per student if each class has 20 students;
cost per student = 2 (4s + 25) / s
cost per student = 2 ( 4×20 + 25)/ 20
cost per student = 2 ( 80 + 25) / 20
cost per student = 2 (105) / 20
cost per student = 210 / 20 = $10.50

15. The table shows the minimum and maximum
elevations, relative to sea level, of several
hiking trails. Which hiking trail has the least
change in elevation, related to sea level?
Explain how you solved.
The hiking trail that has the least change in elevation, related to sea level, is:
Southern Moon.
Which trail has the least change in altitude?The change in altitude of each trail is calculated as the subtraction of the highest altitude by the lowest altitude, that is:
Change in elevation = highest altitude - lowest altitude.
For Eastern Point, the change is given as follows:
Change = 78 - (-85) = 78 + 85 = 163 feet.
(subtracting by a negative is the same as adding to the positive of the number).
For Northern Star, the change is given as follows:
Change = 34 - (-150) = 34 + 150 = 184 feet.
For Southern Moon, the change is calculated as follows:
Change = 48 - (-62) = 48 + 62 = 110 feet.
The smallest amount is of 110, hence Southern Moon has the least change in elevation relative to sea level.

How to translate the vertices of a triangle in a accordance to a vector
Triangles are defined by the locations of its three vertices on Cartesian plane and we must find the locations of the images of the three vertices after applying a translation rule. In this case, we must translate each vertex 2 units upward and 4 units to the right. The general translation formula is described below:
P'(x, y) = P(x, y) + T(x, y)
Where:
P(x, y) - Location of the vertex.T(x, y) - Translation vector.P'(x, y) - Location of the image of the vertex.If we know that C(x, y) = (- 5, - 4) and T(x, y) = (4, 2), then the location of the image of point C is:
C'(x, y) = (- 5, - 4) + (4, 2)

Given vector v as a linear combination of the standard unit vectors i and j would be, vec v = 10 i -4 j
In this question, we have been given a vector whose initial point is (-2, -1) and the final point is (8, -5)
We need to write vector v as a linear combination of the standard unit vectors i and j.
Let (x1, y1) = (-2, -1) and (x2, y2) = (8, -5)
We know that for vector A having initial point (x1, y1) and terminal point (x2, y2), a linear combination of the standard unit vectors i and j is:
vec A = (x2 - x1)i + (y2 - y1)j
So, for given vector it would be,
vec v = (x2 - x1) i + (y2 - y1) j
vec v = (8 - (-2)) i + (-5 - (-1)) j
vec v = (8 + 2) i + (-5 + 1) j

piggy bank contains 2.65$ in nickles and dimes. If the number of nickles is 7 less that three times the number of dimes, how many of each are there?
There are 29 nickels and 12 dimes in the piggy bank.
In this question, we have been given a piggy bank contains 2.65$ in nickels and dimes.
We need to find the number of nickels and dimes if the number of nickels is 7 less than three times the number of dimes.
Let x be the number of nickels and y be the number of dimes.
We know that, 1 dollar = 20 nickels
and 1 dollar = 10 dimes
So, we get an equation
0.05x + 0.1y = 2.65 ...........(1)
Also the number of nickels is 7 less than three times the number of dimes.
x = 3y - 7 .................(2)
Substitute above value of x in equation (1)
0.05(3y - 7) + (0.1)y = 2.65
0.15y - 0.35 + 0.1y = 2.65
0.25y = 2.65 + 0.35
0.25 y = 3
y = 12
Substitute above value of y in equation (2)
x = 3(12) - 7
x = 29
Therefore, there are 29 nickels and 12 dimes in the piggy bank.

The Total Surface Area of the Pyramid with pentagon base can be calculated using the formula
TSA = 5/2*b(a+s) ,
where b is the base length (side of pentagon)
s is the slant height ,
a is the apothem
and the Total Surface Area of the Pyramid with square base can be calculated using the formula .
TSA = b² + 2bs
where , b is the base and
s is the slant height .
Pyramid (a)
we can see from the figure that ,the pyramid has a pentagon base ,
So, the TSA will be 5/2*b(a+s) ,
in the figure , given that height =12 cm , apothem = 7.8cm
we find the slant height by Pythagoras theorem
(slant height)²=(height)²+(apothem)²
(slant height)² = 12² + 7.8²
(slant height) = √(12² + 7.8²)
(slant height) = √(144+60.84)
(slant height) = 14.3 cm
Substituting in TSA formula , TSA = 5/2*b(a+s)
we get ,
TSA = 5/2*11.3(7.8+14.3)
= 2.5*11.3(22.1)
= 28.25*22.1
=624.32 cm²
Pyramid (b)
we can see from the figure that ,the pyramid has a square base ,
So, the TSA will be b² + 2bs,
in the figure , given that height =12 m , apothem = 4 m
we find the slant height by Pythagoras theorem
(slant height)²=(height)²+(apothem)²
(slant height)² = 12² + 4²
(slant height) = √(12² + 4²)
(slant height) = √(144+16)
(slant height) = 12.6 m
Substituting in TSA formula , TSA = b² + 2bs
we get ,
TSA = 8² + 2*8*12.6
= 64 + 16*12.6
= 64 + 201.6

The triangle is Isosceles and Acute.
From the given data, the coordinates of the three points of the triangle are, A(2, 3), B(8, 3), and C(5, 6).
applying the distance formula, D = √((x2-x1)²+(y2-y1)²) the distance AC and BC are obtained as 3√2 and the distance AB as 2√3.
From this, it can be concluded that AC=BC≠AB.
thus since two of the sides, AC and BC are equal and the third side AB is not equal to AC and BC hence the given triangle is an isosceles triangle.
To check whether the given triangle is right, acute.
A right triangle is a triangle with one of its angles equal to 90 degrees.
An acute triangle is a triangle with all three of its angles less than 90 degrees.
An obtuse triangle is a triangle with at least one of its angles greater than 90 degrees.
To check whether the given triangle is right, acute, or obtuse we use the law of cosines.
To find the angle of a triangle given 3 of its sides, let the angle between the sides AB and AC be A then,
cos(A) = (AC² + AB² − BC²)÷(2×AB×AC).
cos(A) = (3√2² + 2√3² - 3√2²)÷(2×2√3×3√2) =2÷√6
[tex]cos^{-1}[/tex](2÷√6) = 39.182.
Let the angle between the sides AB and BC be B then,
cos(B) = (BC² + AB² − AC²)÷(2×AB×BC).
cos(B) = (3√2² + 2√3² - 3√2²)÷(2×2√3×3√2) =2÷√6
[tex]cos^{-1}[/tex](2÷√6) = 39.182.
Let the angle between the sides AC and BC be then,
cos(C) = (AC² + BC² − AB²)÷(2×AC×BC).
cos(C) = (3√2² + 3√2² - 2√3²)÷(2×3√2×3√2) =2÷3

Solve for x :
5x+8=7x-72
Answer:
x = 40
Step-by-step explanation:
We just have to manipulate the terms, putting each term that has the variable "x" on one side of the equation like this:
5x + 8 = 7x - 72
5x - 7x = - 72 - 8
-2x = -80
x = -80/--2
x = 40
Answer:
x = 40
Step-by-step explanation:
Given equation:
[tex]5x+8=7x-72[/tex]
Add 72 to both sides:
[tex]\implies 5x+8+72=7x-72+72[/tex]
[tex]\implies 5x+80=7x[/tex]
Subtract 5x from both sides:
[tex]\implies 5x+80-5x=7x-5x[/tex]
[tex]\implies 80=2x[/tex]
Divide both sides by 2:
[tex]\implies \dfrac{80}{2}=\dfrac{2x}{2}[/tex]
[tex]\implies 40=x[/tex]
Therefore, the solution to the given equation is x = 40.
A group of friends wants to go to the amusement park. They have no more than $195 to spend on parking and admission. Parking is $9.75, and tickets cost $17.75 per person, including tax. Which inequality can be used to determine xx, the maximum number of people who can go to the amusement park?
Answer:
7
Step-by-step explanation:
assuming everyone takes their own car, 9.75+17.75 * 7 = 192 I don’t know the state tax, because each state is different but 192 gives about $3 worth of room for tax. If the tax is higher in your state maybe I’d answer with 6 people. Hope this helped!
