Answer:
Step-by-step explanation:
Given the equation
comparing the equation with the slope-intercept form
Here,
- m is the slope
- b is the intercept
so the slope of the line is m = -2/5
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line,
so the slope of the perpendicular line will be: 5/2
Therefore, the point-slope form of the equation of the perpendicular line that goes through (2,-8) is:
subtract 8 from both sides
Answer:
Option D.
Step-by-step explanation:
Minimize the objective function P = 5x + 8y for the given constraints.
The related equations of above inequalities are
For ,
x y
0 5
7.5 0
Plot (0,5) and (7.5,0) and join them by straight line.
For ,
x y
0 7.5
5 0
Plot (0,7.5) and (5,0) and join them by straight line.
Check the inequalities for (0,0).
False
False
It means both lines are solid lines and shaded region for each lies opposite side of (0,0).
From the below graph it is clear that the vertices of feasible region are (0,7.5), (3,3), (7.5,0).
Point P = 5x + 8y
(0,7.5) P=5(0)+8(7.5)=60
(3,3) P=5(3)+8(3)=15+24=39
(7.5,0) P=5(7.5)+8(0)=37.5 (Minimum)
So, minimum value is 37.5.
Therefore, the correct option is D.
The equation which is equivalent to 16 Superscript 2 p Baseline equal to 32 Superscript p 3 is,
Equivalent equation are the expression whose result is equal to the original expression, but the way of representation is different.
Given information-
The given equation in the problem is,
Write both the equation in the form of same base number as,
The power of the power of a number can be written as product of both the numbers. Thus,
This is the required equation.
Now if the base is the same at both side of the expression, then the powers can be compared. Thus,
Solve it further to find the value of p as,
