Answer:

Step-by-step explanation:

∠B=65°

∠A+∠B+∠C+∠D=360

90+65+∠C+65=360

∠C=360-220=140°

AB=AD (given)

BC=BD (given)

so ∠B=∠D

also sum of four angles of a quadrilateral=360°

ivolga24 [154]

For this case we must find the inverse of the following function:

f (x) = x ^ 2-1

For them we follow the steps:

We change f (x) to y:

y = x ^ 2-1

We exchange variables:

x = y ^ 2-1

We solve for "y":

y ^ 2-1 = x

We add 1 to both sides of the equation:

y ^ 2 = x + 1

We apply square root to eliminate the exponent:

y = \pm \sqrt {x + 1}

We change y by f ^ {- 1} (x):

f ^ {- 1} (x) =\pm \sqrt {x + 1}

Answer:

Option D

Difference between mutually exclusive
denis-greek [22]

Answer:

A mutually exclusive event is when there are two events that can occur, such as flipping a coin, either it will be a head or a tail. Hence, both the events here are mutually exclusive.

An independent event is termed as an event that occurs without being affected by other events. The happening of one event has nothing to do with the happening of the other and there is no cause-effect between the two.
