Answer:

∠M

Step-by-step explanation:

∠M is the only vertex that does not already have an indicated angle. There are three vertexes, being 90° at ∠K (the box-like figure means it is a right angle, therefore 90°) , 61° at ∠N , and ∠M, which does not have a given angle.

Keep answers as exact as possible (NOT IN TERMS OF PI). <br><br>

Andreyy89

Answer:

121.9

Step-by-step explanation:

I will use pi but not in the answer

use formula V=πr²h

(π)(3.5²)(5.5)

12.25 × 5.5=67.375 × π=211.6648...

1/2(4/3(π(3.5³))

4/3(42.875)=57.166...× π = 179.59438...

1/2(179.59438...) = 89.79719...

211.6648... - 89.79719... = 121.86761... ≈ 121.9

Prove that :

Dimas [21]

Answer:

<h3>Question 1</h3>

sec²θ + cosec²θ =
1/cos²θ + 1/sin²θ =
(sin²θ + cos²θ)/(sin²θcos²θ) =
1 / (sin²θcos²θ) =
[(sin²θ + cos²θ)/sinθcosθ]² =
(sinθ/cosθ + cosθ/sinθ)² =
(tanθ + cotθ)²

<h3>Question 2</h3>

(1 - tan²θ) / (1 + tan²θ) =
(1 - sin²θ/cos²θ) / (1 + sin²θ/cos²θ) =
(cos²θ - sin²θ) / (cos²θ + sin²θ) =
(cosθ + sinθ)(cosθ - sinθ) / 1 =
(cosθ + sinθ)(cosθ - sinθ)

<h3>Question 3</h3>

sinθ/ (1 - cotθ) + cosθ / (1 - tanθ) =
sinθ / (1 - cosθ/sinθ) + cosθ / (1 - sinθ/cosθ) =
sinθ/ [(sinθ - cosθ) / sinθ] + cosθ / [(cosθ - sinθ)/cosθ] =
sin²θ/ (sinθ - cosθ) + cos²θ/(cosθ - sinθ) =
sin²θ/ (sinθ - cosθ) - cos²θ/(sinθ - cosθ) =
(sin²θ - cos²θ) / (sinθ - cosθ) =
(sinθ + cosθ)(sinθ - cosθ) / (sinθ - cosθ) =
sinθ + cosθ

Reyna runs a textile company that manufactures T-shirts. The profit, p, made by the company is modeled by the function , where s

Sonja [21]

Answer:

s > 42

Step-by-step explanation: INCOMPLETE QUESTION, PROBLEM STATEMENT DOES NOT GIVE THE MODELING FUNCTION.

I´VE FOUND IN NTERNET PROFIT

p(s) = s² + 9*s - 142

Then we have

s² + 9*s - 142 > 2000

rearrange that inequation

s² + 9*s - 142 > 2000 ⇒ s² + 9*s - 2142 > 0

we complete the expression as a perfect quadratic, with the help of two number that add +9 and multiplying - 2142

Numbers are 51 and - 42

then

factoring that expression as a perfect quadratic

( s + 51 )* ( s - 42 ) > 0

For what have two solution, and we dismiss the negative value since the numbers of shirts could not be negative, we get

s - 42 > 0

s > 42 the solution
