Prove that 1/sec0-tan0= sec0+tan0

Leviafan [203]

Answer:

Step-by-step explanation:

$\text{LHS}=\frac{1}{\sec \theta-\tan \theta}\\=\frac{\sec \theta+\tan \theta}{(\sec \theta-\tan \theta)(\sec \theta+\tan \theta)}\\=\frac{\sec \theta+\tan \theta}{\sec^{2} \theta-\tan^{2} \theta}\\=\frac{\sec \theta+\tan \theta}{1}\\=\sec \theta+\tan \theta\\=\text{RHS}$

Which set of values could be from a direct proportion

mr Goodwill [35]

Answer:

First table

Step-by-step explanation:

We have to find the set of value which could be from a direct proportion.

We know that

Direct proportion :

When x is directly proportional to y

$x\propto y$

$x=ky$

Where k=Proportionality constant

$k=\frac{x}{y}$

K remain constant when x and y are in direct proportion

From first table

$k=\frac{\frac{1}{2}}{6}=\frac{1}{12}$

$k=\frac{1}{12}$

$k=\frac{2}{24}=\frac{1}{12}$

$K=\frac{3}{36}=\frac{1}{12}$

When x and y are both varies then ratio of x and y remain constant.Hence, it is in direct proportion.

From second table

$k=\frac{0}{0}=$ not ]define

$k=\frac{1}{1}=1$

It is not direct proportion because k does not remain constant.

From third table

$k=\frac{0}{2}=0$

$k=\frac{2}{4}=\frac{1}{2}$

It is not direct proportion because k does not remain constant.

Tyler used 1 1/2 gallons of paint to paint 5/7 of a fence. How many gallons will it take to paint the whole fence?

Mademuasel [1]

9514 1404 393

9514 1404 393

Answer:

1) (1 1/2)(7/5) = g

2) (1 1/2)/(5/7) = g

Step-by-step explanation:

1) Tyler has painted 5/7 of the 7/7 of the fence. So the total amount of the fence is (7/7)/(5/7) = 7/5 as much as what was already painted.

The total amount of paint needed is then 7/5 the amount already used:

g = (7/5)(1 1/2) . . . . . gallons of paint needed for the whole fence

__

2) If g gallons are required for the whole fence, the amount used so far for 5/7 of the fence is 5/7 of the quantity required:

(5/7)g = 1 1/2

g = (1 1/2)/(5/7) . . . . division expression for the paint needed
