In the region 0-2, the first derivative has a zero at x=1, and the second derivative (slope of the first derivative line) is positive. This means f(x) will have a minimum at x=1.
Likewise, in the region 4-6, the second derivative is negative and the first derivative is zero at x=5, indicating a maximum there.
These observations narrow the selection to choices A or C. The derivative curve is continuous at x=2 and x=4, so there will not be any discontinuities in f(x)--eliminating selection C.
The best choice is
A.
Step-by-step explanation:
<u>Here :-</u>
- Selling price of 25 balls is equal to the Cost of 15 balls
<u>Let the cost price of one ball is ₹1. So ;-</u>
- Cost price of 25 balls = ₹25
- Cost price of 15 balls = ₹15
↝ Here the selling price of 25 balls is equal to the cost of 15 balls. It means C.P of 15 balls = S.P of 25 balls. So, the selling price of 25 balls is ₹15.
<u>Firstly, finding the loss :-</u>
<em><u>∴ The loss is Rs.10.</u></em>
<u>Now, finding the loss percentage :-</u>
<em><u>∴ The loss percent is 40%.</u></em>
the equation of line that is perpendicular to 2x+y=3 & passes through points (2,-5) is:
Step-by-step explanation:
Given equation of line is:
Let m1 be the slope of given line and
m2 be the slope of line perpendicular to given line
The slope of first line will be (The coefficient of x)
m1 = -2
We know that the product of slopes of two perpendicular lines is -1
So,
slope-intercept form is:
Putting the value of slope we get
Putting the point in the equation
Putting the value of b
Hence,
the equation of line that is perpendicular to 2x+y=3 & passes through points (2,-5) is:
