Answer:

The door is not in rectangle shape.

Step-by-step explanation:

Given:

Length of base = 30 inches

Height of door = 84 inches

Diagonal of door = 91 inches

Find:

The door is rectangle or not

Computation:

Using Pythagorean theorem

Hypotenuse² = Perpendicular² + Base²

So,

91² = 84² + 30²

8,281 = 7,056 + 900

8,281 ≠ 7,956

So we say that the given door angle is not 90°

So,

The door is not in rectangle shape.

First Method:

Round \frac{3}{5} to the closest integer, which is 1.

Round \frac{3}{4} to the closest integer, which is also 1.

So 1 + 1 = 2.

Answer for method 1: 2

Second Method:

\frac{3}{5} + \frac{3}{4} = \frac{3*4}{5*4} + \frac{3*5}{4*5}  = \frac{12}{20}+\frac{15}{20}=\frac{27}{20}

\frac{27}{20} is around 1

Answer for method 2: 1

The closest answer is 1.

2^sinx+2^cosx find the minimum value of this trignometry
Anit [1.1K]
Take the deritiivive
ln(2)cos(x)2^{sin(x)}-ln(2)sin(x)2^{cos(x)}
it is zero at pi/4 and it repeats at every pi
minimum at where slope goesfrom negative to positive
so at 5pi/4 and 13pi/4 so at every 2pi interval


evaluate origial at 5pi/4
2^{sin(5pi/4)}+2^{cos(5pi/4)}=
(2^ \frac{- \sqrt{2} }{2} )+(2^ \frac{- \sqrt{2} }{2} )=
2(2^ \frac{- \sqrt{2} }{2} ) or aprox 1.22509
