Using rectangles whose height is given by the value of the function at the midpoint of the rectangle's base, estimate the area under the graph using first two and then four rectangles 1x)=x² between x 0 and x=1 Using two rectangles to estimate, the area under f(x) is approximately (Type an integer or a simplified fraction) Using four rectangles to estimate, the area under fox) is approximately (Type an integer or a simplified fraction)
4. using two rectangles to estimate, the area under f(x) is approximately 5/16.
To estimate the area under the graph of the function f(x) = x² between x = 0 and x = 1 using rectangles, we can use the midpoint method.
First, let's calculate the width of each rectangle. Since we are using two rectangles, the width of each rectangle is (1 - 0) / 2 = 1/2.
For the first estimate with two rectangles:
1. Find the midpoint of the base of each rectangle:
- The midpoint of the first rectangle is 0 + (1/2) * (1/2) = 1/4.
- The midpoint of the second rectangle is 0 + (1/2) * (3/2) = 3/4.
2. Evaluate the function at the midpoint of each rectangle:
- f(1/4) = (1/4)²
= 1/16.
- f(3/4) = (3/4)²
= 9/16.
3. Calculate the area of each rectangle:
- The area of the first rectangle is (1/2) * (1/16) = 1/32.
- The area of the second rectangle is (1/2) * (9/16) = 9/32.
4. Sum the areas of the two rectangles to get the estimated area under the graph:
- Estimated area = (1/32) + (9/32) = 10/32
= 5/16.
Now, let's use four rectangles for a more accurate estimate:
1. Calculate the width of each rectangle. Since we are using four rectangles, the width of each rectangle is (1 - 0) / 4 = 1/4.
2. Find the midpoint of the base of each rectangle:
- The midpoint of the first rectangle is 0 + (1/4) * (1/4) = 1/8.
- The midpoint of the second rectangle is 0 + (1/4) * (3/4) = 3/16.
- The midpoint of the third rectangle is 0 + (1/4) * (5/4) = 5/16.
- The midpoint of the fourth rectangle is 0 + (1/4) * (7/4) = 7/16.
3. Evaluate the function at the midpoint of each rectangle:
- f(1/8) = (1/8)² = 1/64.
- f(3/16) = (3/16)² = 9/256.
- f(5/16) = (5/16)² = 25/256.
- f(7/16) = (7/16)² = 49/256.
4. Calculate the area of each rectangle:
- The area of the first rectangle is (1/4) * (1/64) = 1/256.
- The area of the second rectangle is (1/4) * (9/256) = 9/1024.
- The area of the third rectangle is (1/4) * (25/256) = 25/1024.
- The area of the fourth rectangle is (1/4) * (49/256) = 49/1024.
5. Sum the areas of the four rectangles to get the estimated area under the graph:
- Estimated area = (1/256) + (9/1024) + (25/1024)
+ (49/1024) = 84/1024 = 21/256.
using four rectangles to estimate, the area under f(x) is approximately 21/256.

In a safari park, the ratio of flamingos to monkeys was 6: 7.
4 monkeys were then born, and the ratio of flamingos to monkeys became 2: 3.
Work out how many flamingos and how many monkeys are in the safari park now.
If the ratio of flamingos to monkeys was 6:7, then in present the number of monkeys is 18 and number of flamingo is 12.
Let "6x" be the number of flamingos and "7x" be the number of monkeys,
After the 4 monkeys were born, the number of monkeys became 7x + 4, and the ratio of flamingos to monkeys became 2:3.
This means that the number of flamingos is now 2/3 of the total number of monkeys,
Which is : 2/3(7x + 4) = 6x,
Simplifying further,
We get,
⇒ 2(7x + 4) = 18x,
⇒ 14x + 8 = 18x
⇒ 8 = 4x
⇒ x = 2
So, there were 6x = 12 flamingos and 7x = 14 monkeys in the safari park before the 4 monkeys were born.
After the 4 monkeys were born, the number of monkeys became 14 + 4 = 18, and the new ratio of flamingos to monkeys is 2:3,
Which means the number of flamingos is 2/5 of total-number of animals.
⇒ 2/5(12 + 18)
⇒ 12
Therefore, there are currently 12 flamingos and 18 monkeys in the safari park.

Graph the system of inequalities. Then use your graph to identify the point that
represents a solution to the system.
X > -2
y≤ 2x + 7
(-1,6)
(1, 11)
(-1,4)
(-3,-1)
The solution to the system of inequalities is (-1, 4).
To graph the system of inequalities and identify the point that represents a solution, we will plot the lines corresponding to the inequalities and shade the regions that satisfy the given conditions.
The first inequality is x > -2, which represents a vertical line passing through x = -2 but does not include the line itself since it's "greater than." Therefore, we draw a dashed vertical line at x = -2.
The second inequality is y ≤ 2x + 7, which represents a line with a slope of 2 and a y-intercept of 7.
To graph this line, we can plot two points and draw a solid line through them.
Now let's plot the points (-1, 6), (1, 11), (-1, 4), and (-3, -1) to see which one lies within the shaded region and satisfies both inequalities.
The graph is attached.
The dashed vertical line represents x > -2, and the solid line represents y ≤ 2x + 7. The shaded region below the solid line and to the right of the dashed line satisfies both inequalities.
By observing the graph, we can see that the point (-1, 4) lies within the shaded region and satisfies both inequalities.
Therefore, the solution to the system of inequalities is (-1, 4).

6. To check whether the rose bush lies on the circle, see if its coordinates make the
equation for the circle true. Show your work (2 points)
Part of question :
(x-10)^2+(y-10)^2=100
(16-10)^2+(18-10)^2=100
Answer:
Yes, equation of circle is true
Step-by-step explanation:
(x-10)^2+(y-10)^2=100
(16-10)^2+(18-10)^2=100
100=100
plugging the coordinates into the equation of the circle, we observe that the equation is true since both sides of the equation are equal(value on both sides of the equal sign are same). This wouldn't be true if for instance the left side of the equation evaluated to ≠100. Therefore we can conclude that the rose bush lies on circle since the equation is true

the perimeter of the triangle below is 38 units. Find the length of side WX. Write your answer without variables
Answer:
5.5
Step-by-step explanation:
Add each side of the triangle.
3z+z+1+4z-3 = 8z - 2
8z - 2 is equivalent to the perimeter.
Since you know the perimeter is 38 units, you can set 8z-2 to 38.
8z-2 = 38
Solve for z. Subtract 2 from each side.
8z = 36
Divide each side by 8.
z = 4.5
Now solve for side WX.
WX = z + 1
WX = 4.5 + 1
WX = 5.5

If you move line m, what happens? if you move line r?
Moving line m will likely result in a change in the position or alignment of the element or object associated with line m. Moving line r, on the other hand, will likely result in a change in the position or alignment of the element or object associated with line r.
When line m is moved, it can affect the arrangement or relationship of elements or objects that are connected or associated with it. This could include shifting the position of a graphic or adjusting the layout of a design. For example, in a floor plan, moving line m could change the location of a wall, thereby altering the overall structure of the space. Similarly, in a musical composition, moving line m could involve adjusting the melody or rhythm, leading to a different arrangement of notes and chords.
Similarly, when line r is moved, it can have an impact on the position or alignment of the element or object it is associated with. This could involve repositioning a visual element, such as adjusting the angle of a line or changing the alignment of text. For instance, in a website layout, moving line r might result in shifting the position of a sidebar or adjusting the spacing between columns. In a mathematical graph, moving line r could involve modifying the slope or intercept, thereby changing the relationship between variables.
In summary, moving line m or line r can bring about changes in the position, alignment, or arrangement of associated elements or objects. The specific outcome will depend on the context in which these lines are being moved and the nature of the elements they are connected to.

Given f (x) = x2 + 5x + 6, what is [picture included] equal to?
h2 + 14h

h + 4
9 + h
The difference quotient evaluated in x = 2 gives:
[ f(2 + h) - f(2)]/h = h + 9
So the last option is the correct one.
How to find the difference quotient evaluated in 2?
Here we know the function:
f(x) = x^2 + 5x + 6
And we want to find the difference quotient:
[ f(2 + h) - f(2)]/h
Let's evaluate the function:
f(2 + h) = (2 + h)^2 + 5*(2 + h) + 6
= 2^2 + h^2 + 4h + 10 + 5h + 6
= h^2 + 9h + 20
f(2) = 2^2 + 5*2 + 6
f(2) = 4 + 10 + 6 = 20
Then we have:
[ f(2 + h) - f(2)]/h
[h^2 + 9h + 20 - 20]/h
[h^2 + 9h ]/h
Taking the quotient we get:
[h^2 + 9h ]/h = h + 9

Rob bought a hat and 3 shirts for $35 . Dan bought 2 hats and a shirt for $20 Which system of equations can be used to find s , the cost of one shirt, and h, the cost of one hat?
Answer:
1x+3y=35, 2x+y=20
x=5, y=10
Step-by-step explanation:
Let x equal the number of hats and y equal number of shirts.
Solve by substitution, elimination, or graphing.
Personally, I just solved by substitution.
Solve for x (or y) in the first equation. Let's do x.
1x+3y=35 goes to 1x=35-3y or just x=35-3y.
Since we have x, plug it in the other equation. 2(35-3y)+y=20. This equals out to y=10, i assume you understand the algebra.
Plug 10 into either equation for y.
1x+3(10)=35 or x+30=35. subtract 30 on each side. X=5.
