The value of the tangent when the angle is from 180 to 270 is 0.9392. Then the correct option is B.

Trigonometry deals with the relationship between the sides and angles of a right-angle triangle.

If sine Θ almost equals negative 0.7660.

Then the angle will be

[tex]\theta = sin ^{-1} (-0.7660)\\\\\theta = -49.996^o[/tex]

The interval of the angle is from 180 degrees to 270 degrees. Then we have to add 270 degrees in the angle. Then the angle will be

[tex]\theta = -49.996^o + 270^o\\\\\theta = 220.0039^o[/tex]

Then the tangent of Θ will be given as

[tex]tan \theta = tan \ (220.0039^o) = 0.8392[/tex]

Have a great day

Answer:

Period:  [tex]4\pi[/tex]

Midline:  y = 2

Amplitude:  3

Range:   [-1, 5]

Step-by-step explanation:

Period - from one peak to the next (or from one trough to the next)

⇒ Period:  [tex]2\pi - (-2\pi )=4\pi[/tex]

Midline - center line

Range = -1 ≤ f(x) ≤ 5

[tex]\implies \sf midline =\dfrac{5-(-1)}{2}+(-1)=2[/tex]

⇒ Midline:  y = 2

Amplitude - height from the center line to the peak (or to the trough)

Maximum height:  y = 5

center line:  y = 2

Therefore, amplitude = 5 - 2 = 3

Range - the set of all values that the function takes

-1 ≤ f(x) ≤ 5  →  [-1, 5]

Period:-

Only one peak is shown so we take distance between troughs

Answer:

2/3.

Step-by-step explanation:

Geometric mean  = √(2 * 2/9)

= √(4/9)

= 2/3.

The geometric mean between 2 and 2/9 is 2/3.

We can define the mean of the given data set as the average of all the

numbers. Mathematically, we can write mean as -

M = ∑x{i}/n

Given is to find the geometric mean between 2 and 2/9.

The general formula used to calculate the geometric mean is -

[tex]$\left(\prod _{i=1}^{n}x_{i}\right)^{\frac {1}{n}}={\sqrt[{n}]{x_{1}x_{2}\cdots x_{n}}}[/tex]

We can write the geometric mean between 2 and 2/9 as -

GM = √(2 x 2/9)

GM = √(4/9)

GM = √4/√9

GM = 2/3

Therefore, the geometric mean between 2 and 2/9 is 2/3.

The dimensions of the rectangular area of Tina's fence is 40 ft by 40 ft

where

l = length

w = width

She wants to create a rectangular area of 1,600 square feet for her pet . Therefore,

lw = 1600

Therefore,

perimeter = 160 ft

Then,

perimeter of rectangle = 2(l + w)

160 = 2(l + w)

l + w = 80

Let's combine the equations

lw = 1600

l + w = 80

l = 80 - w

Therefore,

w(80 - w) = 1600

80w - w² = 1600

Therefore,

w² - 80w + 1600 = 0

w² - 40w - 40w + 1600 = 0

w(w - 40) - 40(w - 40) = 0

(w - 40)(w - 40) = 0

w = 40 or 40

Therefore, the dimensions can be calculated as follows:

lw = 1600

40l = 1600

l = 1600 / 40

l = 40 ft

Therefore, the dimensions are 40ft by 40 ft

Answer:

y = x/2 means that it's whatever x is and that divided by 2

Step-by-step explanation:

For example for 8 it would be y=8/2 which is 4

14 would be 7

3 would be y= 3 x 2 your multiplying because the value is y so it's 6

Answers (from top to bottom)

Reasoning:

The rule says if you know what x is, divide by 2 to get y

In the first row, if x = 8, then y = x/2 = 8/2 = 4.

In the second row, x = 14 leads to y = 7 since 14/2 = 7.

The third row has us go in reverse. We multiply the y value by 2 to find x

This is because y = x/2 solves to x = 2y. So if y = 3, then x = 2y = 2*3 = 6.

We can then check this to get y = x/2 = 6/2 = 3.
