The answer would be the third one .
Perpendicular would always be the opposite of your original slope.
Hope this helps! (:
Answer:
D is the correct choice
Step-by-step explanation:
To get the y-intercept, we write the equation in the standard form
The standard form is ;
y = mx + b
So we have to rewrite the equation this very form
Thus, we have that;
0.05y = 0.4x + 1.25
we simply isolate the y value
To do this, we divide through by 0.05 and the y-intercept value will be ;
1.25/0.05 = 25
Answer:
the zero of a function is the value of x which makes the final value zero
First Equation:
So let 25 - 2x equal to 0
<em>25 - 2x = 0</em>
x = 12.5
Second Equation:
Let 2x² - 11x - 6 equal to zero
<em>2x² - 11x - 6 = 0 </em>
<em>2x² - 12x + x - 6 = 0 </em><em>(Splitting the middle term)</em>
<em>2x(x - 6) + 1(x - 6) = 0</em>
<em>(2x + 1) (x - 6) = 0</em>
So we can transpose either one of the brackets below the zero
(2x + 1) = 0 or (x-6) = 0
x = -1/2 or x = 6
You can build a cylinder in two ways: either you draw a circle on a plane, and "raise" it perpendicularly to the plane itself, or you start with a rectangle, and rotate it around one of its sides.
For these reasons, if you cut the cylinder with a plane parallel to the base you have a circular cross section, while if you cut the cylinder with a plane perpendicular to the base you have a rectangular cross section.
