Use complete sentences to describe the range of the sine function.
alisha [4.7K]
The Range of a function is the set of all values that that function can take.

Given the sine function f(x)=sinx,

This function is the function which calculates the sine of the values of x.

According to the definition of the sine of an angle x in the unit circle, 

-1 \leq sinx \leq 1,

so the sine of an angle is always larger or equal to -1, and smaller or equal to 1.

This means that the values that the sine function takes are any values between -1 and 1, inclusive.

This determines the Range of the sine function. 

So the Range of the sine function is [-1, 1]

An observer (O) spots a plane (P) taking off from a local airport and flying at a 33° angle horizontal to her line of sight and
lana [24]

Answer:

Option D. 10,779 feet

Step-by-step explanation:

Given from the figure attached,

PT = OB = 7000 ft

PB = OT = x feet

and angle of elevation (∠POT) = 30°

By applying Tan rule in the triangle POT,

tan33° = \frac{\text{Opposite side}}{\text{Adjacent side}} = \frac{PT}{OT}

tan33° = \frac{7000}{x}

x = \frac{7000}{\text{tan}33}

x = 10779 feet

Therefore, distance between the bird (B) and plane (P) is 10,779 feet.

Option D. will be the answer.

How to solve y=2x+5 and y=3x-1 by a system of linear equations by substitution
Ronch [10]

Answer:

x = 6, y = 17

Step-by-step explanation:

These equations are both equal to y.

Substitute 3x - 1 in the y value of the first equation.

3x - 1 = 2x + 5

Subtract 2x.

x - 1 = 5

Add 1 to both sides

x = 6

Then substitute this x value into the first equation.

y = 2x + 5

y = 2(6) + 5 = 12 + 5 = 17
