The answer is 79 because 9/10 divided by 71.1 is 79. And if you want to check, you can multiply 9/10 by 79, which will give you 71.1. I hope this helped :)

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

Find the slope of the line that passes through the points A (3, -1), B (3,5) *

Harman [31]

Answer:

0 or infinity i believe

Step-by-step explanation:

slope equation is rise over run or y2-y1 over x2 - x1, so 5 - (-1) turns into 5+1 because of the double negative so that equals six. then 3-3 is 0 so it would be 6 over zero and by dividing that'd equal zero aka infinity for slope

By remainder theorem, find the remainder of p(x) when it is divided by g(x), where p(x)= x^3-2x^2-4x-1, g(x)= x+1

Anuta_ua [19.1K]

By the remainder theorem the remainder when dividing p(x) by x-a is p(a).

Dividing by x+1 means we want p(-1).

p(-1) = (-1)³ - 2(-1)² -4(-1) - 1 = -1 - 2 + 4 - 1 = 0

Answer: 0

They go in evenly so x+1 is a factor of p(x).
