Answer:

True

Step-by-step explanation:

Given : Expression \csc^{-1}[\csc(-\frac{\pi}{4})]=-\frac{\pi}{4} and \sec[{\sec^-1}(\sqrt3)]=\sqrt3

To find: The given expression are true or false?

Solution :

In the given expression,

Applying Inverse trigonometric functions,

i.e, f(f^{-1}x)=x

or \csc^{-1} (\csc x)=x\\\csc(\csc^{-1} x)=x

and this true for all trigonometric functions.

So, if apply in the given expression the resultant we get is true.

\csc^{-1}[\csc(-\frac{\pi}{4})]=-\frac{\pi}{4} is true

and \sec[{\sec^-1}(\sqrt3)]=\sqrt3 is true

Therefore, The given expressions are true.

The length of a parking Lot is 5 yards more than the width. If the area of the parking lot is 66 square yards, find the dimensio
Brums [2.3K]

Answer:

  6 yards by 11 yards

Step-by-step explanation:

Factors of 66 are ...

  66 = 1·66 = 2·33 = 3·22 = 6·11

The last pair of factors differ by 5, so represent the solution to the problem.

The width of the parking lot is 6 yards; the length is 11 yards.

Find the y-intercept and the x-intercept of the line 2x-4y=10
kompoz [17]
Finding y intercept and x intercept is easy:

X intercept will be of the form (x,0) and y intercept will be of the form (0,y)

● If you put x=0 in the equation, you will get y-intercept.

● If you put y=0 in the equation, you will get x-intercept.
______________________________

Given equation: 2x - 4y = 10

◆ Put x = 0
2×0 - 4y = 10
=> -4y = 10
=> y = 10/(-4)
=> y = -5/2

Thus y intercept is (0, -5/2)

◆Put y = 0
2x - 4×0 = 10
=> 2x = 10
=> x = 10/2
=> x = 5

Thus the x intercept is (5,0)
