Find the area bounded by the curves y = x/2 and y =√x.
Answers
Answer:
[tex]\displaystyle \frac{4}{3}[/tex].
Step-by-step explanation:
Start by finding the intersection of the two curves:
[tex]\left\lbrace\begin{aligned}& y = \frac{x}{2} \\ & y = \sqrt{x} \\ & x \ge 0 \\ \end{aligned}\right.[/tex].
[tex]\displaystyle \frac{x}{2} = \sqrt{x}[/tex] while [tex]x \ge 0[/tex].
[tex]\displaystyle \frac{x^{2}}{4} - x = 0[/tex].
[tex]x = 0[/tex] or [tex]x = 4[/tex].
Therefore, these two curves would intersect at two points: [tex](0,\, 0)[/tex] and [tex](4,\, 2)[/tex].
The area bounded between [tex]\displaystyle y = \frac{x}{2}[/tex] and [tex]y = \sqrt{x}[/tex] would be between [tex]x = 0[/tex] and [tex]x = 4[/tex].
Refer to the diagram attached. The graph [tex]y = \sqrt{x}[/tex] is always above the graph of [tex]\displaystyle y = \frac{x}{2}[/tex] over the entire bounded area (except for the two intersections).
Therefore, [tex]\displaystyle \left(\sqrt{x} - \frac{x}{2}\right)[/tex] would represent the vertical distance between the upper and lower curve for any given [tex]x[/tex] over this bounded area (where [tex]0 \le x \le 4[/tex].)
Integrating height over the horizontal variable [tex]x[/tex] over some closed interval would give area. Likewise, the area between the two curves in this question could be found with the following integral:
[tex]\begin{aligned}& \int\limits_{0}^{4} \left(\sqrt{x} - \frac{x}{2}\right)\, dx \\ = \; & \int\limits_{0}^{4} \left(x^{1/2} - \frac{x}{2}\right)\, dx \\ =\; & \left[\frac{2}{3}\, x^{3/2} - \frac{x^{2}}{4}\right]_{x=0}^{x=4} \\ =\; & \frac{2\times 8}{3} - 4 \\ =\; &\frac{4}{3} \end{aligned}[/tex].

Answers
Answer:
(x+x)^2=4-x
Step-by-step explanation:
I think, don't be mad if I'm wrong!
The approach used seems to be:
Step 1: Make the first term x^2 not 2x^2, by dividing every term by 2.
x^2 + 1/2 x - 2=0
Note here that because the computer had “+” before the second box in the first line, you needed to put “-2” instead of 2 to keep the sign correct.
Step 2: Move that -2 to the other side and then figure out what you’re going to add to the right side to complete the square. The way you do this is you take the “b” value from “bx” and divide it by 2 and square it.
Divide b by 2: 1/2 ÷ 2 = 1/2 • 1/2 = 1/4
Square that: (1/4)^2 = 1/16
So you need to add 1/16 to both sides.
The final step is to factor the left side and add the numbers on the right side.
Left side: x^2 + 1/2x + 1/16 = (x+1/4)^2.
The 1/4 can be found either by dividing the “b” by 2 or taking the square root of 1/16. Both give you 1/4.
You can always double check your work by FOILing out (x+1/4)^2 as (x+1/4)(x+1/4) and making sure you get used 1/4 correctly.
On the right side, 2 + 1/4 = 2/1 + 1/4 = 8/4 + 1/4 = 9/4
You need to find a common denominator to add them.
The above process will always work. How messy it is totally depends on the numbers involved.
h=54+1/2at^2 solve for a
Im lost on if I should square the 1/2at first?
Answers
Other answer formats are possible.
===========================================================
Explanation:
Let's say we want to solve the equation h = 54 + 10a for the variable 'a'. This is relevant to the problem at hand don't worry.
What we'd do is two things
Subtract 54 from both sides Divide by 10So the steps look like this
h = 54 + 10a
h-54 = 10a
(h-54)/10 = a
a = (h-54)/10
Now let's say we wanted to solve this equation: h = 54 + ca, where c is a constant and can stand in place of any number. The steps would be pretty much identical. Instead of dividing both sides by 10, we divide both sides by c. We can do this as long as c isn't zero of course.
That means the equation h = 54+ca solves to a = (h-54)/c
---------------------------
Why did I do those examples? To build up to the equation your teacher gave you.
Let's replace c with 0.5t^2
This is because 1/2 = 0.5
The 1/2at^2 is the same as (1/2t^2)a
So instead of a = (h-54)/c, we'd get a = (h-54)/(0.5t^2)
As a last optional and encouraged step, we can multiply every term by 2 to get rid of that decimal value.
Doing so makes a = (h-54)/(0.5t^2) turn into a = (2h-108)/(t^2)
---------------------------
Here's another way to solve:
h = 54 + (1/2)at^2
h-54 = (1/2)at^2
2(h-54) = at^2
2h-108 = at^2
(2h-108)/(t^2) = a
a = (2h-108)/(t^2)
In the second step, I subtracted 54 from both sides. Immediately afterward, I multiplied both sides by 2 so I could clear out the fraction. Then I divided both sides by t^2 to fully isolated the variable 'a'.

What is the mean, median and mode for...45,50,55,55,55,60,60,60,65,65,70?
Answers
Answer:
Mean = 58.18
Median = 60
Modes = 55 and 60
Step-by-step explanation:
To find the mean/average, add up all the numbers and divide the sum by the # of numbers there are (ex. there are 11 numbers so divide the sum by 11).
The median is the middle number of a set. In this case, the middle number is easy to see because the # of numbers is odd, but if it was even, just find the average of the two middle numbers.
The mode is/are the most frequent number(s) in the set. In this set, the numbers that appear the most are 55 and 60.

Answer:
m∠QRS = 80°
Step-by-step explanation:
We know that, sum of supplementary angles is 180°.
Given that ∠ABC and ∠QRS are supplementary, and m∠ABC = 100°.
So, m∠ABC + m∠QRS = 180°
=> 100° + m∠QRS = 180°
=> m∠QRS = 180° - 100°
=> m∠QRS = 80°

Step-by-step explanation:
Y2-y1/x2-x1
The slope of the given line is m = 4.
Given,
Point A has coordinates (-6, -2).
Point B has coordinates (-4,6).
We need to find what is the slope of a line segment connecting the two.
What is the slope of a line between two points?If the two points are (x_1, y_1) and (x_2, y_2).
Then the slope is given by:
m = (y_2 - y_1) / (x_2 - x_1)
Find the slope.
Let,
(-6, -2) = (x_1, y_1)
(-4, 6) = (x_2, y_2)
m = (y_2 - y_1) / (x_2 - x_1)
m = (6 - (-2)) / (-4 - (-6))
m = (6 + 2) / (-4 + 6)
m = 8 / 2
m = 4
Thus the slope of the given line is m = 4.

The actual selling price was 20% below the cost price, so was ...
sp = cp(1 -20%) = 0.80cp
Had the selling price been raised, the selling price would have been 5% above the cost price:
sp +800 = cp(1 +5%) = 1.05cp
Subtracting the first equation from the second gives ...
(sp +800) -(sp) = (1.05cp) -(0.80cp)
800 = 0.25cp . . . . . . . simplify
3200 = cp . . . . . . . . multiply by 4
