An old principle of public landscaping says "build sidewalks last." In other words, let
the people find their chosen paths and then build the sidewalks on the paths. The
picture below shows a campus quadrangle that measures 40 meters by 30 meters.
The path between each building is an illustration of Pythagoras theorem.
The sidewalk between library and humanities is 21.21 metersThe sidewalk between chemistry and humanities is 29.15 metersThe sidewalk between chemistry and humanities is 36.06 metersSee attachment for a copy of the given image.
The sidewalk between library and humanities
This is represented with (a).
The value of (a) will be calculated using Pythagoras theorem.
So, we have:
[tex]a^2 = 15^2 + 15^2[/tex]
[tex]a^2 = 450[/tex]
Take square roots
[tex]a = 21.21[/tex]
Sidewalk between chemistry and library
This is represented with (d).
First calculate the value of (b) and (c)
[tex]c + 15 = 30[/tex]
So:
[tex]c = 15[/tex]
Also:
[tex]b + 15 = 40[/tex]
So:
[tex]b = 25[/tex]
The value of (d) will be calculated using Pythagoras theorem.
[tex]d^2 = b^2 + c^2[/tex]
[tex]d^2 = 25^2 + 15^2[/tex]
[tex]d^2 = 850[/tex]
Take square roots
[tex]d = 29.15[/tex]
The sidewalk between chemistry and humanities
This is represented with (e).
The value of (e) will be calculated using Pythagoras theorem.
[tex]e^2 = d^2 + a^2[/tex]
[tex]e^2 = 850 + 450[/tex]
[tex]e^2 = 1300[/tex]
Take square roots
[tex]e = 36.06[/tex]

The graph of a function g is shown below.
Use the graph of the function to find its average rate of change from x=-1 to x=3.
Simplify your answer as much as possible.
Step-by-step explanation:
the rate of change (like the slope for a line) is expressed by y/x.
for x = -1 we get y = -3
for x = 3 we get y = 5
so, while x changes by 4 units (-1 to +3), y changes by 8 units (-3 to +5).
so, the average change rate in that interval is 8/4 = 2/1 = 2

The hundreds digit of my number is less

the tens digit. What could my number be?
Answer:
Step-by-step explanation:
6 7 8 is one possibility
789 is another choice.
123 even works.
So how many numbers are there like this?
You can't have 0 in the 100s place and you can't have 8 0r 9
So there are 7 numbers 1 2 3 4 5 6 7 possible choices for the hundreds.
You can't 0 in the tens place nor 1 nor 9
You can't have 0 or 1 or 2 in the units place

Use the midpoint formula to find the midpoint of the segment whose endpoints are
(3,-2) and (-5, 8).
O (4, 5)
.0 (-1, )
O (1, -3)
0 (-1, 3)
Answer:
(-1;3)
(3 - 5)/2 = -1
(-2 + 8)/2 =3
Midpoint of segment (3, -2) and (-5, 8) is (-1, 3).
The midpoint formula allows us to find the point that lies exactly halfway between two given points on a line segment. For two points represented as (x₁, y₁) and (x₂, y₂), the midpoint ([tex]x_m[/tex], [tex]y_m[/tex]) is calculated using the formula:
[tex]x_m[/tex] = (x₁ + x₂) / 2
[tex]y_m[/tex] = (y₁ + y₂) / 2
Now, let's apply this formula to find the midpoint of the segment with endpoints (3, -2) and (-5, 8):
x₁ = 3, y₁ = -2
x₂ = -5, y₂ = 8
[tex]x_m[/tex] = (3 + (-5)) / 2 = (-2) / 2 = -1
[tex]y_m[/tex] = (-2 + 8) / 2 = 6 / 2 = 3
So, the midpoint of the segment is (-1, 3).
In this explanation, we used the midpoint formula, represented by the subscript "m," to find the midpoint ([tex]x_m[/tex], [tex]y_m[/tex]) of the segment with endpoints (x₁, y₁) and (x₂, y₂). By substituting the given coordinates into the formula, we computed the x-coordinate and y-coordinate separately. The midpoint gives the exact center of the segment, dividing it into two equal parts. In this case, the midpoint lies at (-1, 3), which is indeed the point that is equidistant from both (3, -2) and (-5, 8) on the line segment.

The value of a car dropped from $23,600 to $21,900 over the last year. Determine the actual and relative change in this situation.
Actual Change: ? This car's value decreased by $
last year.
Round your answer to the nearest dollar.
Relative Change: ? This car's value decreased by
% last year.
Round your answer to the nearest tenth of a percent.
Answer:
The actual change in the car's value is $[tex]1700[/tex] and the relative change is [tex]7.20[/tex]%.
Step-by-step explanation:
It is given that the value of a car is dropped from $[tex]23600[/tex] to $[tex]21900[/tex].
So, the change in the value is the drop in the value of car, which is, [tex]23600-21900=1700[/tex].
So, the actual change in this car's value is $[tex]1700[/tex].
The relative change can be given by the expression,
[tex]\dfrac{\:\rm{Actual Change}}{\:\rm{Original Value}}\times100[/tex]
Substituting values, the relative change can be given by,
[tex]\begin{aligned}\dfrac{1700}{23600} \times 100&=\dfrac{1700}{236}\\&=7.20\end{aligned}[/tex]

. Pencils are sold in packages of 10, and erasers are sold in packages of 6. What is the least number of pencils and erasers you can buy so that there is one pencil for each eraser with none left over?
Answer:
3 packs of pencils
5 packs of erasers
Step-by-step explanation:
To solve this problem, find the least common multiple. The least common multiple is the smallest number that both terms are a factor of. In this case, that number is 30. Both 10 and 6 are a factor of 30. So, the answer is the other factor needed to get 30 through multiplication. 10's other factor is 3 and 6's other factor is 5. Therefore, the answers are 3 and 5 respectively.

g(x) = x2 + 7x+ 5
Composition of functions how to solve value of g [f(4)]
9514 1404 393
Answer:
g(f(4)) = -1
Step-by-step explanation:
Evaluate this the way you would any function. Start with the inner parentheses according to the order of operations. Substitute for the function variable and do the arithmetic.
g(f(4)) = g(-4·4 +10) = g(-6) = (-6)² +7(-6) +5 = 36 -42 +5
g(f(4)) = -1

Please help me. 20 Points with explanation.
Answer:
See Below.
Step-by-step explanation:
Square roots deal with multiplication, so if you can simplify to an even square, you can pull out the integer.
sqrt(75) = sqrt(25×3) = sqrt(25)×sqrt(3) = 5×sqrt(3)
((50 is 25×2, so same 5, but with sqrt(2), not 3))
So...
5 / (5×sqrt(3) - 5×sqrt(2)) = 5 / (5×(sqrt(3) - sqrt(2)))
5's cancel out
1 / (sqrt(3) - sqrt(2))
If you multiply top and bottom by (sqrt(3) + sqrt(2)) (which doesn't technically alter anything, since anything over itself is just 1), you get...
(sqrt(3) + sqrt(2)) / ((sqrt(3))^2 - (sqrt(2))^2 + (sqrt(3)×sqrt(2)) - (sqrt(2)×sqrt(3)))
Which simplifies to...
(sqrt(3) + sqrt(2)) / (3 - 2) = (sqrt(3) + sqrt(2)) / 1 = sqrt(3) + sqrt(2)
