The focal length F of a lens made by combining two lenses of focal length U and V is given I/F=I/U+I/V

jolli1 [7]

Answer:

a). $V=\frac{U.F}{U-F}$

b). V = 15 units

Step-by-step explanation:

Focal length F of a lens made by combining two lenses of different focal lengths U and V will be,

$\frac{1}{F}=\frac{1}{U}+\frac{1}{V}$

A). By solving the given formula,

$\frac{1}{V}=\frac{1}{F}-\frac{1}{U}$

$\frac{1}{V}=\frac{U-F}{U.F}$

$V=\frac{U.F}{U-F}$

B). If F = 6 and U = 10 then we have to find the value of V.

By substituting the given values in the formula,

$V=\frac{6\times 10}{10-6}$

$V=\frac{60}{4}$

V = 15 units

Therefore, focal length (V) of the lens = 15 units

Two points on a line L are (5,2) and (7,-4). what is the slope of L

klemol [59]

Answer:

-3

Step-by-step explanation:

The slope of a line can be calculated with the formula (y2-y1)/(x2-x1)

In this case we have:

(-4-(2))/(7-5)

(-6)/(2)

-3

Let me know if this helps!

How to convert standard form to slope intercept form??

zubka84 [21]

Hi there!
To convert an equation from standard form to slope-intercept form, you need to pull the x over to the other side by making it 0 (by either subtracting or adding that number on both sides):

4x + 2y = 10----> 2y = -4x + 10

Now, we simply divide both sides by the coefficient on y and there you have it!

y = -2x + 5
