It's C. -26. Since they're both negative you, you add: -71 + 45 = -26.

What are the period and vertical shift of the cosecant function below?
lutik1710 [3]

Answer:

y=acsc(bx-c)+d\\y=csc(\frac{1}{2}x)+2\\P=\frac{2\pi}{b}\Rightarrow P=\frac{2\pi}{\frac{1}{2}} \Rightarrow P = 2\pi*2 \Rightarrow P=4\pi\\d=2

Step-by-step explanation:

The trigonometric functions have some features like amplitude, period, phase shift, and vertical shift.

Retrieving the original cosecant graph and copying and attaching it below we have this function:

y=cosec(\frac{1}{2})x+2

1) Period

Since the period of a basic secant and basic sine function 2\pi

y=acsc(bx-c)+d\\y=csc(\frac{1}{2}x)+2\\P=\frac{2\pi}{b}\Rightarrow P=\frac{2\pi}{\frac{1}{2}} \Rightarrow P = 2\pi*2 \Rightarrow P=4\pi

2) Vertical Shift

This value affects the graph by displacing it from x-axis.

The Vertical Shift does not need calculation for it is given by the parameter "d"

y=acsc(bx-c)+d\\y=csc(\frac{1}{2}x)+2\\ d=2 \: (Vertical\:Shift)

Please help. Brainliest.

C.) 2 is the right answer

Step-by-step explanation:

Given

-15(x-__)=25

We can see in the next step

-15x+30=25

We can check by substituting each option one by one

So,

A.) -30

-15(x-(-30))=25\\-15(x+30)=25\\-15x-150=25

We can see that by putting -30 we don't get the expression given in the picture so it is not the right answer.

B.) -2

-15(x-(-2))=25\\-15(x+2)=25\\-15x-30=25

We can see that by putting -2 we don't get the expression given in the picture so it is not the right answer.

C.) 2

-15(x-2)=25\\-15x+30=25

We get the same expression by putting 2 in the blank so it is the right answer.

Hence,

C.) 2 is the right answer

In ASTU, MZS = (2x + 10)°, mZT = (3x – 9)°, and mZU = (6x-19)<br> Find mZT.
Sonja [21]

9514 1404 393

Answer:

  m∠T = 45°

Step-by-step explanation:

The sum of angles in a triangle is 180°, so ...

  (2x +10)° +(3x -9)° +(6x -19)° = 180°

  11x -18 = 180 . . . . . collect terms, divide by °

  11x = 198 . . . . . . . . add 18

  x = 18 . . . . . . . . . . . divide by 11

Then the angle of interest is ...

  m∠T = (3x -9)° = (3·18 -9)°

  m∠T = 45°

_____

The other angles are ...

  m∠S = 46°

  m∠U = 89°
