Answer:
Rs. 7245
Step-by-step explanation:
Given parameters:
Cost price = Rs. 6300
Percentage profit = 15%
Unknown:
Selling price = ?
Solution:
If profit is made on a trade, the selling price is higher than the cost price.
Profit = Selling price - Cost price
To find the selling price simply;
Selling price =( 1 + ) x cost price
Selling price = 1.15 x 6300 = Rs. 7245
Answer: the equation of the standard parabola
1)
The equation of the standard parabola
2) (x+5)^2 = 16(y-2)
Step-by-step explanation:
<u>Explanation </u>
<u>Parabola:-</u>
The set of points in a plane whose distance from a fixed point and a constant ratio to their corresponding perpendicular distance from a fixed straight line is a conic.
Let S be a fixed point and l be a fixed straight line from any point P,the perpendicular PM is drawn to the line 'l'
- The locus of P such that
- The fixed point 'S' is called the Focus.
- The fixed line'l 'is called the directrix of the conic
- The constant ratio is known as the eccentricity, denoted by 'e'
- If e=1 , the conic is called a parabola
1) <u> Step 1</u> :-
Given the focus S = (2,6) and directrix is x=0
we know that
now cross multiplication , we get
squaring on both sides,we get
step 2:-
now using distance formula is
Given S =(2,6) and P(x,y) be any point on parabola
........(1)
Now using perpendicular distance formula
let P(x , y ) be any point on the parabola
Given the directrix is x =0 and P(x,y) be any point on parabola
......(2)
equating equation(1) and equation (2), on simplification
we get .....(3)
- apply
now the equation (3) is
now the standard form of parabola is
<u>Final answer</u>:-
2) <u> Explanation:-</u>
<u>step 1:</u>
Given vertex of a parabola is A(-5,2) and its focus is S(-5,6)
here the given points of 'x'co- ordinates are equal
- Therefore the axis AS is parallel to y- axis
now the standard equation of parabola
now you have to find' a' value
Given vertex of a parabola is A(-5,2) and its focus is S(-5,6)
The distance of
on simplification we get a =4
<u>Final answe</u>r :-
the vertex (h,k) = (-5,2) and a=4
The standard parabola is
Okay Bright, so the central angle is 36 degrees, so according to the formula you have on the top of the screen, we have to do 36/360, which is 1/10 or 0/1.
Then we multiply that by the radius squared. 12^2 = 144.
Finally, we multiply 144 by 0.1, which is 14.4. So our answer is H. 14.4
.
Notice that we don't multiply the radius squared by, since the answers are in terms of .
Hope this helped!
