Answer:

  -29/20

Step-by-step explanation:

The cosecant function is the inverse of the sine function. Both sine and cosecant are odd functions, meaning csc(-x) = -csc(x) = -1/sin(x).

  csc(-θ) = -1/sin(θ) = -1/(20/29) = -29/20

Write an exponential equation in the form y = ab^x whose graph passes through points (4, 8) and (6, 32).
luda_lava [24]

Answer:

(1,4),(2,12)

----------

The form is y = ab^x

12 = ab^2

4 = ab^1

------------

Divide the 1st by the 2nd to get:

3 = b

--------

Substitute that into the 2nd equation to solve for "a":

4 = a*3^1

a=(4/3)

-------------

EQUATION:

y = (4/3)*2^x

Which of the following functions I which of the following functions are one to one? Select all that apply there are 3 answers
ivann1987 [24]

Answer:

The function f(x)=\frac{x-1}{3x+3} is one-to-one function ⇒ 1st

The function f(x)=\sqrt{5x+9} is one-to-one function ⇒ 2nd

The function f(x)=\frac{1}{2}x^{3} is one-to-one function ⇒ 4th

Step-by-step explanation:

* Lets explain how to solve this problem

- One to one function is the function that has no reputation in the value

 of the y-coordinates for every corresponding x-coordinates

- That means when you draw a horizontal line at any value of y, then

  the horizontal line intersects the graph of the function at one point

  only

- So to solve the problem look to the attached figures

# The red graph of the function f(x)=\frac{x-1}{3x+3} ⇒1st graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at only one point

- Take care there is a horizontal asymptote at y= 1/3, that means

  there is no value of x at y = 1/3

∴ The function f(x)=\frac{x-1}{3x+3} is one-to-one function

# The blue graph of the function f(x)=\sqrt{5x+9} ⇒2nd graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at only one point

∴ The function f(x)=\sqrt{5x+9} is one-to-one function

# The green graph of the function f(x)=\frac{1}{2}x^{3} ⇒3rd graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at only one point

∴ The function f(x)=\frac{1}{2}x^{3} is one-to-one function

# The purple graph of the function f(x)=\frac{7}{4x^{2}} ⇒5th graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at more than one point

∴ The function f(x)=\frac{7}{4x^{2}} is not one-to-one function

# The black graph of the function f(x)=3x^{4}+7x^{3} ⇒4th graph

- In this graph if we draw a horizontal line at any value of y it will

 intersect the graph at more than one point

∴ The function f(x)=3x^{4}+7x^{3} is not one-to-one function

* The answers are 1st , 2nd and 4th functions
