Find the gain percent in the following:
Cost Price Rs 280,
(a) Selling Price
Rs 290
Answer:
3.57
Step-by-step explanation:
P=SP -CP
=290-280=10
P%=[tex]\frac{P*100}{CP}[/tex]
=[tex]\frac{10*100}{280}[/tex]
=[tex]\frac{1000}{280}[/tex]
=3.57
-[tex]-\frac{1}{2}[/tex] x + y = 10
Step-by-step explanation:
y = mx + c
is this form
-1/2x + y = 10
we need to get y by its self
to do that move -1/2x to the other side
do u know how to do that
Answer:
Slope = 1.000/2.000 = 0.500
x-intercept = 20/-1 = -20.00000
y-intercept = 20/2 = 10
Step-by-Step Explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-1/2*x+y-(10)=0 <----- given linear equation
STEP 1:
Simplify 1/2
Equation at the end of step 1:
((0 - (1/2 • x)) + y) - 10 = 0
STEP 2 : Rewriting the whole as an Equivalent Fraction
Adding a whole to a fraction
Rewrite the whole as a fraction using 2 as the denominator :
y = y/1 = y · 2/2
Equivalent fraction :
The fraction thus generated looks different but has the same value as the wholeCommon denominator :
The equivalent fraction and the other fraction involved in the calculation share the same denominatorAdding fractions that have a common denominator :
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
-x+y• 2 /2 = 2y-x/2
Equation at the end of step 2:
(2y-x)/2-10=0
Step 3:
Rewriting the whole as an Equivalent Fraction :
Subtracting a whole from a fraction
Rewrite the whole as a fraction using 2 as the denominator :
10=10/1=10 * 2/2
Adding fractions that have a common denominator :
Adding up the two equivalent fractions
(2y-x)-(10*2)/2=-x+2y-20/2
Step 4:
Pulling out like terms :
Pull out like factors :
-x + 2y - 20 = -1 • (x - 2y + 20)
Equation at the end of step 4:
-x+2y-20/2=0
Step 5: When a fraction equals zero :
When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
-x+2y=20/2 *2=0*2
Now, on the left hand side, the 2 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
-x+2y-20 = 0
Equation of a Straight Line
Solve -x+2y-20 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line -x+2y-20 = 0 and calculate its properties
Graph of a Straight Line : PICTURE
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 10/1 so this line "cuts" the y axis at y=10.00000
y-intercept = 20/2 = 10
Calculate the X-Intercept :
When y = 0 the value of x is 20/-1 Our line therefore "cuts" the x axis at x=-20.00000
x-intercept = 20/-1 = -20.00000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 10.000 and for x=2.000, the value of y is 11.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 11.000 - 10.000 = 1.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 1.000/2.000 = 0.500
Geometric figure: Straight Line
Slope = 1.000/2.000 = 0.500
x-intercept = 20/-1 = -20.00000
y-intercept = 20/2 = 10

HELP FAST!!
(m+nx)/(m-n)=(p+qx)/(p-q) if mq=np
Basically all you need to show is –(p-q)=(-p)+q. (1)
Since 0 = (p-q) + (-(p-q)) (additive inverse), we get –p = -q +(-(p-q)). Now substitute for (–p) in (1).
Then m+q-n-p=(m+q)-(n+p) follows. (since -n-p+(n+p) = 0 implies -n-p = -(n+p) (additive inverse))
so technically all u need to show is –(p-q)=(-p)+q. Hope this helps!!

Hello people ~
plot the graph of y=cos x
Step-by-step explanation:
[tex]\displaystyle \boxed {y = sin\:(x + \frac{\pi}{2})} \\ y = Asin(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 0 \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \hookrightarrow \boxed{-\frac{\pi}{2}} \hookrightarrow \frac{-\frac{\pi}{2}}{1} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{2\pi} \hookrightarrow \frac{2}{1}\pi \\ Amplitude \hookrightarrow 1[/tex]
OR
[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A| \\ \\ Vertical\:Shift \hookrightarrow 0 \\ Horisontal\:[Phase]\:Shift \hookrightarrow 0 \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \hookrightarrow \boxed{2\pi} \hookrightarrow \frac{2}{1}\pi \\ Amplitude \hookrightarrow 1[/tex]
You will need the above information to help you interpret the graph. First off, keep in mind that although this looks EXACTLY like the cosine graph, if you plan on writing your equation as a function of sine, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = sin\:x,[/tex]in which you need to replase "cosine" with "sine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the cosine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the sine graph [photograph on the right] is shifted [tex]\displaystyle \frac{\pi}{2}\:unit[/tex]to the right, which means that in order to match the cosine graph [photograph on the left], we need to shift the graph BACKWARD [tex]\displaystyle \frac{\pi}{2}\:unit,[/tex]which means the C-term will be negative, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{-\frac{\pi}{2}} = \frac{-\frac{\pi}{2}}{1}.[/tex]So, the sine graph of the cosine graph, accourding to the horisontal shift, is [tex]\displaystyle y = sin\:(x + \frac{\pi}{2}).[/tex]Now, with all that being said, in this case, sinse you ONLY have a wourd problem to wourk with, you MUST use the above formula for calculating the period. Onse you do that, the rest should be easy. Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = 0,[/tex]in which each crest is extended one unit beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.
I am delighted to assist you at any time.
Answer:
Properties of y = cos(x)
The cosine wave is a sinusoidal function (sine and cosine waves are the same except for a horizontal shift).
It is a continuous function and so its domain is (-∞, ∞)
The center line is y = 0
The Amplitude (the height from the center line to the peak) is 1, and so its range is -1 ≤ x ≤ 1
The y-intercept is at (0, 1)
Its period (length of one wave) is 2π (360°)

Answer:
h = 3.6
Step-by-step explanation:
This is just substituting in for variables and solving for x. The hard part is knowing the formula.
R = h((a+b)/2) where a and b are the 2 different bases, h is the height or latitude, and R is the area of a trapezoid, is the formula.
Given that R = 8.1, a = 1 and b = 3.5, we can substitute these equations in the formula.
(8.1) = h(((1) + (3.5)) / 2)
= h((4.5) / 2)
= h(2.25)
8.1/2.25 = h
3.6 = h
If b + 2a = c and 2a +b = 10, then what is c
