the diagram shows a circle inside a square ABCDB AB = 20 cm. the radius of the circle is 9 cm. work out the area of the shaded region
Step-by-step explanation:
Area of the square = a²
= 20²
= 400cm²
Area of the circle = πr²
= 22/7 × 9²
= 22/7 × 81
= 254.57cm²
Area of the shaded region = Area of the square - Area of the circle
= 400cm² - 254.57cm²
= 145.43cm²
What is the slope, y-intercept, and equation of a line given the points (-4, 0) and (1, 5)?
Slope:
y-intercept:
Equation:
Answer:
[tex]Slope: 1\\y-Intercept: 4\\Equation: y = x + 4[/tex]
Step-by-step explanation:
Given two points, we can find the equation of the line between them with the following:
[tex]y = mx + b\\m = \frac{y_2-y_1}{x_2-x_1}[/tex]
First, we can calculate m, or slope
[tex]m = \frac{y_2-y_1}{x_2-x_1} = \frac{5-0}{1-(-4)} = \frac{5}{5} = 1[/tex]
Next we can use the top equation and solve for b, the y-intercept
[tex]y = mx + b\\y = x + b\\5 = (1) + b\\b = 4\\\\y = x + 4[/tex]
[tex]Slope: 1\\y-Intercept: 4\\Equation: y = x + 4[/tex]
Find the equation of the line that passes through (1,-1) and is parallel to 2x+y−3=0.
Leave your answer in the form y=mx+c
Answer: y= -2x + 1
Step-by-step explanation:
We can formulate the slope equation of that line by
S= Y-Y1/X-X1
By the given statement "parallel", the slope of the function "y=3-2x" shall then equals the first line -->1
to conclude, we will use the first point at x=1 ( Like the given point of the line) and additional point at x=0...
y(1)=3-2(1)=1, Hence, (1,1)
y(0)=3-2(0)=3, Hence, (0,3)
By the fact 1
then we shall conclude with simple linear equation as follow
m=y2-y1/x2-x1 = 1-3/1-0=-2
The general formula of the Required function is y=mx+c
In fact the line passes through the point (1,-1)
Hence y in x=1 equals -1
-1= -2(1)+C
C= -1+2=1
Then FINALLY the line formula isy= -2x + 1what's y intercept on a graph of y = -5x + 6
The y-intercept on a graph of y = -5x + 6 is 6.
What are intercepts?The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.
We have a linear equation,
y = -5x + 6.
The general slope-intercept form,
y = mx + b.
Where m is the slope and b is the y-intercept.
Comparing,
b = 6.
Therefore, 6 is the y-intercept.

a) The value of a is
(-3,4)
A: negative
B: zero
C: positive
b) The value of c is
A: negative
B: zero
C: positive
c) The solutions of y=ax*2+ bx + c = 0 are
A: both negative
B: both positive
C: one negative and one positive
Answer:
A, A and A
Step-by-step explanation:
Given
y = ax² + bx + c
• If a > 0 then minimum vertex
• If a < 0 then maximum vertex
Here the vertex is a maximum, thus a < 0 , that is negative → A
The value of c is the y- intercept
The graph crosses the y- axis below the y- axis, thus c is negative → A
The solutions to ax² + bx + c = 0 are the values of x on the x- axis where the graph crosses the x- axis.
The graph crosses the x- axis to the left of the y- axis , thus
Both solutions are negative → A

Write the equation of the line in slope-intercept form.
11. A line that passes through (3, 1) and (0, -3)
Answer:
y=(4/3)x - 3
Step-by-step explanation:
Use equation (y-y1) =m (x-x1)
slope is m= (y1-y2)/(x1-x2)=1+3/3-0=4/3
use one of the points and this slope to complete the equation
(y-1)=(4/3)(x-3) distribute and add1 to both sides
y=(4/3)x-(3*4/3)+1
y=(4/3)x - 3
Answer:
y = [tex]\frac{4}{3}[/tex] x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, 1) and (x₂, y₂ ) = (0, - 3)
m = [tex]\frac{-3-1}{0-3}[/tex] = [tex]\frac{-4}{-3}[/tex] = [tex]\frac{4}{3}[/tex]
The line crosses the y- axis at (0, - 3) ⇒ c = - 3
y = [tex]\frac{4}{3}[/tex] x - 3 ← equation of line

The area of this figure is 80 square units.
Write an equation for the area of the shape below.
Answer:
Step-by-step explanation:
A = 12 × 16 + (1/2)(12 + 8)(10) = 292 units²
The Equation for Area of figure is area of Figure, h² + 1/2(h)(b) = 80
What is Area?The measurement that expresses the size of a region on a plane or curved surface is called area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

The front and back covers of a textbook are each 0.3 cm thick. Between the covers are 200 sheets of paper, each 0.008 cm thick. How high is a stack of 10 books
Answer:
22 cm
Step-by-step explanation:
Start off by multiplying the number of pages by the thickness.
200*0.008=1.6
Add the thickness of the front and back cover.
1.6+0.6=2.2
Multiply by 10.
2.2*10=22 cm
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The height of the 10 stacks of books is 22cm.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that the front and back covers of a textbook are each 0.3 cm thick. Also, there are 200 sheets of paper between the cover and the thickness of each sheet is 200 sheets. Therefore, the thickness of the book is,
The thickness of a single book
= (Number of covers × Thickness of cover) + (Number of sheets × Thickness of sheets)
= (2 × 0.3cm) + (200 × 0.008cm)
= 2.2 cm
Now, the thickness of 10 books will be,
The thickness of 10 books = 10 × the Thickness of a single book
= 10 × 2.2 cm
= 22 cm
Hence, the height of the 10 stacks of books is 22cm.

You have quarters. You find % more quarters in your room. Then you go shopping and spend % of the total number of quarters. Write an expression to represent the total number of quarters you take with you shopping. Calculate, in dollars, the amount of money you have left.
Complete question :
You have 20 quarters. You find 40% more quarters in your room. Then you go shopping and spend 50% of the total number of quarters.
A. Write an expression that represents the total number of quarters you take with you when you go shopping.
B. How much money do you have left?
Answer:
[20 + (0.4*20)] = 28 quarters
$3.5
Step-by-step explanation:
Given that:
Initial number of quarters = 20
Quarters in room = 40%
Hence, Numbe of quarters in room = 0.4 * 20 = 8
Total number of quarters taken for shopping :
(Initial amount + Numbe of quarters in room)
(20 + 8) = 28 quarters
50% of quarters was spent on shopping :
0.5 * 28 = 14 quarters
Total left :
28 - 14 = 14
Quarters left in dollars :
1 quarter = 25 cent = 0.25 dollars
14 * $0.25 = $3.5

Write an equation of a line that has a slope of -2 and passes through the point (1,4)
Answer:
y = -2x + 6
Step-by-step explanation:
Since we already have the slope we just need to find the y-intercept.
To do that just plug in the point you were given. (1,4)
4 = -2(1) + b (b represents the y-intercept)
4 = -2 + b (add 2 on both sides)
6 = b
y = -2x + 6 is the equation
Hope this helps!!
Answer:
The equation (in y=mx+b form) would be y= -2x+6
Step-by-step explanation:
The slope is given from the start, which is -2, so you would plug that in for m to make the equation y=-2x but this IS NOT YOUR ANSWER
I was able to graph it, although there are multiple ways to do this.
Next you have to find the y-intercept. You use your coordinate (1,4) and go up twice (positive) (1,6) and go to the left (negative) to get the point (0,6) giving you your intercept.
Plugging it into the equation for b, your equation would now be y= -2x + 6 giving you your final answer
