Step-by-step explanation:

5. I assume you mean this:

(cos²x / sin x) + sin x

Add using common denominator.

(cos²x / sin x) + (sin²x / sin x)

(cos²x + sin²x) / sin x

Use Pythagorean identity.

1 / sin x

csc x

6. tan²x cos²x

Write tangent in terms of sine and cosine.

(sin²x / cos²x) cos²x

Simplify.

sin²x

Answer:

∠Q = ∠U = 60°

Step-by-step explanation:

Construct the figure QSUT with your own dimensions as long as QR ≅ RU and SR ≅ RT , where R is the common midpoint.

I choose QR = 4 cm and SR = 5  cm

Then measure ∠Q and ∠U to check if they are equal.

I got that ∠Q = ∠U = 60° proving that;

∠Q ≅ ∠U

find a rational number that is between 5.2 and 5.5. Explain why it is rational Find an irrational number between 5.2 and 5.5. Ex
DedPeter [7]

A rational number is 5.3 . It's rational because it can be written as a fraction a/b

- that is 5 3/10 or   53/10.

An irrational number between the 2 values would be √29

Enter this into ur calculator and you'll get an answer like 5.385164807  but this number  carries on beyond bounds and can't be written as a fraction a/b  It is irrational.

Graphing Exponential Functions In Exercise, sketch the graph of the function.
denis23 [38]

Answer:

The graph of the function f(x) = (1/2)^2x + 4 is attached as image below.

Analysis:

We have two intersection points in the graph

The function f(x) = (1/2)^2x + 4  intersects the y-axis at points (0,4)

The function f(x) = (1/2)^2x + 4  intersects the x-axis at points (-16,0)

f(x) is positive for x>-`16

f(x) is negative for x<-`16
