The proof will be given as:- $\dfrac{tanx+Cotx}{Coscx Cosx} = Sec^2x$ .

<h3>What is trigonometry?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The proof will be given as:-

$\dfrac{tanx+Cotx}{Coscx Cosx} = \dfrac{tanx}{coscxCosx}+\dfrac{Cosx}{CoscxCosx}\\\\$

$\dfrac{tanx+Cotx}{Coscx Cosx} =\dfrac{\dfrac{Sinx}{Cosx}}{\dfrac{Cosx}{Sinx}}+\dfrac{\dfrac{Cosx}{Sinx}}{\dfrac{Cosx}{Sinx}}$

$\dfrac{tanx+Cotx}{Coscx Cosx} = \dfrac{Sin^2x}{Cos^2x}+1$

$\dfrac{tanx+Cotx}{Coscx Cosx} = tan^2x+1}$

$\dfrac{tanx+Cotx}{Coscx Cosx} =Sec^2x$

Therefore the proof will be given as:- $\dfrac{tanx+Cotx}{Coscx Cosx} = Sec^2x$ .

Given that ,

A number is taken away from 40 and the result is 45 .

Let :-

The required number be x .

According to Question :-

$:\implies$ 40 - x = 45

$:\implies$ - x = 45 - 40

$:\implies$ - x = 5

$:\implies$ x = -5

The main tank at an aquarium is a cylinder with a diameter of 203 ft and a height of 25 ft. Find the volume of the tank to the n

emmasim [6.3K]

In order to find the volume of the tank, you just need to use this formula :

V = π r^2 h

r = 101.5 ft (half the diameter)
h = 25 ft

V = π (101.5)^2 x 25

= 809462.5 ft^3

What is 1 4 add 2 5 in frations

fgiga [73]

Answer:

$\frac{1}{4} +\frac{2}{5}= \frac{13}{20}$

Decimal form: 0.65

Step-by-step explanation:

$\frac{1}{4} +\frac{2}{5}$

To add, you need to get the denominators to be the same, so find the lowest number that both 4 and 5 fit into (multiplication):

4, 8, 12, 16, 20

5, 10, 15, 20

20 is the lowest common multiple of both. So multiply $\frac{1}{4}$ by 5 (both top and bottom) and $\frac{2}{5}$ by 4 (top and bottom) so that the denominators will have the same value:

$\frac{1(5)}{4(5)}+ \frac{2(4)}{5(4)}$

Simplify

$\frac{5}{20}+ \frac{8}{20}$

Now you can add the numerators. Keep the denominators the same:

$\frac{13}{20}$

This is the most simplified version.
