The area of the school is about 827 m² less than the area of the museum.
What is area?Area is the amount of area occupied by an object's flat (2-D) surface or shape.
Given:
Sammy finds satellite images of a school and a museum. They put the images on a coordinate grid (shown below).
School coordinate values are in meters.
To find the area of the school:
The school is rectangular.
Area of the rectangle = length x width
To find the length,
use distance formula.
We interpreted coordinates,
Fort length (-20, 20) and (-40, 80)
For width (-50, 10) and (80, -20)
Distance of length = √(60)²+(-20)² = 20√10
Distance of width = √(30)²+(10)² = 10√10
Area of the rectangle = length x width
Area of the rectangle = 20√10 x 10√10 = 2000 m²
The area of the museum is πr².
And r = 30
The area of the museum = π(30)². ≈ 2827 m².
Subtracting the area's = 827 m².
Therefore, the area of the school is about 827 m² less than the area of the museum.

Find the area of each figure. Round your answer to 2 decimal places if required. (Use = 3.14 if needed)
Answers
Answer:
285 ft²
Step-by-step explanation:
Hello There!
The figure shown is a composite figure so in order to find the total area we are going to need to split the irregular figure into two regular figures:
A parallelogram with the following dimensions
base = 15
height = 7
and a trapezoid with the following dimensions
base 1 = 11
base 2 = 13 (found by subtracting the height of the parallelogram ( 7 ) from the total height of the composite figure ( 20 ) 20 - 7 = 13 so the length of base 2 is 13 ft)
height = 15
Now that we have identified each dimensions of the two regular figures we need to find the area of each individual figure
For the parallelogram
The area of a parallelogram can simply be found by multiplying the height and the base
So A = 15 * 7
15 * 7 = 105 so the area of the parallelogram is 105 square feet
For the Trapezoid
The area of a trapezoid can be found by using this formula
[tex]A=\frac{a+b}{2} h[/tex] where a and b = bases and h = height
So using the information that we had found about the trapezoids dimensions we plug in the values
[tex]A=\frac{11+13}{2} 15\\11+13=24\\\frac{24}{2} =12\\12*15=180[/tex]
So the area of the trapezoid is 180 square feet
Finally we add the areas of the two regular figures
180 + 105 = 285
so we can conclude that the area of the composite figure is 285 ft²

Answer:
Option A. x = –5 ± √133 / –6
Step-by-step explanation:
0 = –3x² + 5x + 9
From the above equation the following data were obtained:
Coefficient of x² (a) = –3
Coefficient of x (b) = 5
Constant (c) = 9
Using formula method, the solution to the equation can be obtained as follow:
x = –b ± √(b² – 4ac) / 2a
a = –3
b = 5
c = 9
x = –5 ± √(5² – 4 × –3 × 9) / 2 × –3
x = –5 ± √(25 + 108) / –6
x = –5 ± √133 / –6
Thus, option A gives the correct answer to the question.
F’(x)= 1+3 square root x f(9)=68
Answers
Answer:
[tex]f(x) = x + 2x^\frac{3}{2} + 5[/tex]
Step-by-step explanation:
I'm assuming the question here is asking for f(x)
The first step would be to find the antiderivative of f'(x)
[tex]\int{1+3\sqrt{x}} \, dx = \int{1 + 3x^\frac{1}{2}} dx[/tex]
Apply the reverse power rule
[tex]x + 2x^\frac{3}{2} + C[/tex]
Now solve for C when x = 9
[tex]x + 2x^\frac{3}{2} + C = 68\\9 + 2(9)^\frac{3}{2} + C = 68\\9 + 2(27) + C = 68\\9 + 54 + C = 68\\63 + C = 68\\C = 5[/tex]
Now substitute into the antiderivative
[tex]f(x) = x + 2x^\frac{3}{2} + 5[/tex]

A single-server waiting line system has an arrival pattern characterized by a Poisson distribution with 3 customers per hour. The average service time is 12 minutes. The service times are distributed according to the negative exponential distribution. The average time a customer can expect to wait in line is:
Answers
Answer:
18 minutes
Step-by-step explanation:
Given that:
The arrival time = 3 customers / hour
The avg. service rate (s) = 12 minutes per customer
To hour, we have:
[tex]s = \dfrac{60}{12}[/tex]
s = 5 customers/ hour
Thus, the required average time for a customer needs to wait in line is:
[tex]= \dfrac{3}{5}\times (5-3) hours \\ \\ = \dfrac{3}{5}\times 2 \\ \\ = \dfrac{3}{10} \ hours[/tex]
To minutes;
[tex]= 3 \times \dfrac{60}{10} \ minutes[/tex]
= 18 minutes
