If the point (x, square root 3/2) is on the unit circle, what is x?

photoshop1234 [79]

Answer:

$\frac{1}{2}$

Step-by-step explanation:

On a unit circle, the only points where y = $\frac{\sqrt{3} }{2}$ have an x coordinate of $\frac{1}{2}$ or $\frac{-1}{2}$ . Since only one of those is an option, the answer is $\frac{1}{2}$ .

5^2x * 5^3 =5^9 what is x please help

erastovalidia [21]

Answer:

x = 3

Step-by-step explanation:

${5}^{2x} \ast {5}^{3} = {5}^{9} \\ {5}^{2x + 3} = {5}^{9} \\ 2x + 3 = 9 \\ (bases \: are \: equal \: so \: exponents \: will \: also \: \\ be \: equal) \\ 2x = 9 - 3 \\ 2x = 6 \\ x = \frac{6}{2} \\ \huge \red { \boxed{x = 3}}$

Prove : (sec θ - tan θ )^2 = 1 - sin θ /1+sin θ

labwork [276]

$(sec x - tan x)^2 \\ \\ = sec^2x - 2 sec x tan x + tan^2 x \\ \\ =(1+tan^2 x) - 2 sec x tan x +tan^2 x \\ \\ =1 - 2 sec x tan x + 2 tan^2 x \\ \\ = 1 - 2tan x(sec x - tan x) \\ \\ =1 - \frac{2 sin x}{cos x} (\frac{1-sin x}{cos x}) \\ \\ = 1 - \frac{2 sin x (1-sin x)}{cos^2 x} \\ \\ =1 - \frac{2 sin x (1-sin x)}{1-sin^2 x} \\ \\ =1 - \frac{2 sin x (1-sin x)}{(1-sin x)(1+sin x)} \\ \\ =1-\frac{2 sin x}{1+sin x}$

A square pyramid is shown. What is the surface area?

ICE Princess25 [194]

Answer:The answer is B

Step-by-step explanation:

first find te height:

1.5/2=0.75 (this will be your "b" of the pythagorean theorem for finding the height)

now do the pythagorean theorem:

a^2+0.75^2=3^2

(height)= 2.905

A= a^2+2a√((a^2/4)+h^2)

a (base edge)= 1.5

h (height)= 2.905

Calculate and you get B as your answer.

Hope this elpsand you get this right!
