If sine theta almost-equals negative 0.7660, which of the following represents an approximate value of tangent theta, for 180 degrees less-than-theta less-than 270 degrees? 0.7660 0.8392 1.1916 1.4198
The value of the tangent when the angle is from 180 to 270 is 0.9392. Then the correct option is B.
What is trigonometry?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]

Which student correctly translated the phrase ""twice the sum of a number cubed and nine"" and evaluated it for r = 3? Antonio's work. 2 (r cubed 9) = 2 (3 cubed 9) = 2 (9 9) = 2 (18) = 36. Jessica's work. 2 (r cubed 9) = 2 (3 cubed 9) = 2 (27 9) = 2 (36) = 72. Maria's work. 2 r cubed 9 = 2 3 cubed 9 = 2 27 9 = 29 9 = 38. Mark's work. 2 3 r 9 = 2 3 (3) 9 = 2 9 9 = 11 9 = 20.

Tina is planning to fence in an area for her dog. She wants to create a rectangular area of 1,600 square feet for her pet and can afford to purchase 160 feet of fence. In two or more complete sentences, explain the algebraic model, calculations and reasoning necessary to determine the dimensions of the rectangular area.
The dimensions of the rectangular area of Tina's fence is 40 ft by 40 ft
Area of a rectangle:area = lwwhere
l = length
w = width
She wants to create a rectangular area of 1,600 square feet for her pet . Therefore,
area = 1600 ft²lw = 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

Use 3.14 for PI
please answer i will give brainliest
Solution:
We know that:
Radius: Diameter/2Area of circle: (π)(r²)Step-1: Find the radius:
Diameter = 22 mm=> Radius: 22 mm/2=> Radius: 11 mmStep-2: Find the area of the circle:
Area of circle = (π)(r²)=> Area of circle = (3.14)(11²)=> Area of circle = (3.14)(121)=> Area of circle = 3.14 x 121 = 379.94 mm²[tex]\\ \rm\Rrightarrow Area=\pi r^2[/tex]

Find the equation of the line that passes through (3,1) and is parallel to y=3−2x. Leave your answer in the form y=mx+c
How do I find the equation of the line y=mx + C, passing through the points M (-2, -3) and T (3, 7)?
How do I find the equation of the line y=mx + C, passing through the points M (-2, -3) and T (3, 7)?
A2A
y = mx + C is often called slope-intercept form.
There are two pieces of information you will need to solve for. #1: The slope, which is m, and #2: the y-intercept, which is C (incidentally I learned this as y = mx + b, instead of y = mx + C, but that is a trivial detail)
Step #1 Find the slope. use the formula slope = (y₂ - y₁)/(x₂ - x₁) => (7 - -3)/3 - -2) = 10/5 = 2. m=2
Step #2 Find the y-intercept. Solve for y = mx + C when x is 2 and x = -2 and y = -3 -3 = 2(-2) + C => -3 = -4 + C add 4 to both sides, 1 = C
Equation: y = 2x + 1.
Check: x = 3 => y = 2(3) + 1 => y = 6 + 1 => y = 7 => (3, 7)
Check: x = -2 => y = 2(-2) + 1 => y = -4 + 1 => y = -3 => (-2, -3)
State the period, midline, amplitude, and range of the given graph. (I will mark brainliest, my answers were wrong!)
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]

geometric mean between 2 and 2/9
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.
What is mean?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.
