Find the value of x.
A) 870
C) 127°
E) 66°
B) 106°
D) 100°
Answer:
100
Step-by-step explanation:
y + 140 = 180 {Linear pair}
y = 180 - 140
y = 40
Given triangle is an isosceles triangle.
x + y + y = 180 {angle sum property of triangle}
x +2y = 180
x +2*40 = 180
x + 80 = 180
x = 180 - 80
x = 100

The curve above the graph of a sinusoidal function. It goes through the points (-11,0) and (3,0). Find a sinusoidal function that matches the given graph.if needed you can enter pi=3.1416… as pi in your answer otherwise use at least 3 decimal digits.
F(x)=
Considering the zeros, the graph for the sinusoidal function is:
[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]
The zeros given for the function are: [tex]x = -11, x = 3[/tex].For practicality, we are going to define a sine function, which has a zero at x = 0, so we use shifting.The sine function is given by:
[tex]F(x) = A\sin{Bx}[/tex]
In which:
The amplitude is A.The period is [tex]T = \frac{2\pi}{B}[/tex].In this problem:
We suppose an amplitude of 1, thus [tex]A = 1[/tex].The difference between the zeros is 14, so we use a period of 14, thus [tex]T = 14[/tex], and:[tex]\frac{2\pi}{B} = 14[/tex]
[tex]B = \frac{2\pi}{14}[/tex]
[tex]B = \frac{\pi}{7}[/tex]
Thus:
[tex]F(x) = \sin{\frac{\pi}{7}x}[/tex]
Like this, the zeros are at [tex]x = -14[/tex] and [tex]x = 0[/tex]. We want it at [tex]x = -11, x = 3[/tex], thus, we shift the function 3 units to the right, that is, the function is:
[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]
The graph is sketched at the end of this answer, and has the desired behavior, which are points (-11,0) and (3,0).

You have a rectangular prism as shown below. Its height is 7 cm, its width is 4 cm, the length is 3 cm. How would we calculate this volume?
9514 1404 393
Answer:
84 cm³
Step-by-step explanation:
There are formulas for the volumes of simple geometric solids: prism, cylinder, pyramid, cone, frustum of a pyramid or cone.
The formula for the volume of a rectangular prism is ...
V = LWH . . . . . product of Length, Width, and Height
Put the numbers in place of the corresponding variables and do the arithmetic.
V = (3 cm)(4 cm)(7 cm) = 84 cm³
The volume of this rectangular prism is 84 cubic centimeters.

A = 16[tex]x^{10}[/tex]
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the side length )
Here s = 4[tex]x^{5}[/tex] , then
A = [tex](4x^5)^{2}[/tex]
= 4 × 4 × [tex]x^{5}[/tex] × [tex]x^{5}[/tex]

The value of y is directly proportional to the value of x.
If y = 10 when x = 5, what is the value of the following.
a) find the value of y when x is equal to 4.
b) find the value of x when y is equal to 6
Answer:
a) find the value of y when x is equal to 4.
Step-by-step explanation:
Answer:
a) the value of y will be x=5 - 4= 1
therefore y=1
b) the value of x will be y= 10 - 6= 4
therefore x=4

What is the length of DE
A. 18
B. 12
C. 10
D. 22
Answer:
the length of DE is A) 18
Step-by-step explanation:
these triangles are similar so you need to create a proportion!
since sides DF and FE are the same, it means that AC and CB are the same!
now we have to find the hypotenuse for DE, which is X
- set up a proportion!
side AC/side AB = side DF/side DE ----> 15/27 = 10/x
- butterfly multiply to get 15x = 270
- divide both sides by 15 to isolate x
now you get --------> x = 18!

What are similar triangle ?Similar triangles have the same form but differ in size. Similar items include all equilateral triangles and squares of any side length. In other words, if two triangles are comparable, their corresponding angles and sides are in proportion.

Graph the image of the given triangle after a rotation of 180° about the origin
Answer:
The bottom point is at (-1, 1) the right point is at (6,-2) and the left point is at (-5,4)
Step-by-step explanation:
Rotation of any polygon about the origin gives the opposite sign coordinate of the original figure thus new coordinate will be (1,-1),(2,-6), and (5,-4).
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If a coordinate of any polygon (x,y) is rotated 180 degrees about the origin either clockwise or anticlockwise then its coordinate will change sign.
(x,y) → (-x,-y)
Given triangle have coordinates as (-1,1),(-2,6), and (-5,4).
The transformation (x,y) → (-x,-y) gives ;
(-1,1) → (1,-1)
(-2,6) → (2,-6)
(-5,4) → (5,-4)
Hence "Rotation of any polygon about the origin gives the opposite sign coordinate of the original figure thus new coordinate will be (1,-1),(2,-6), and (5,-4)".

Write an equation of the parabola in intercept form (3, 4) (4,0) (2,0)
An equation of the parabola is y=?
The equation of the parabola is gotten as;
y = -4x² + 24x - 32
We are given the coordinates of a parabola to be;
(3, 4) ; (4,0) ; (2,0)
The general form of equation of a parabola is given by;
y = ax² + bx + c
Let's plug in the x and y coordinates as given to us from the question.
For coordinate (3, 4), the equation is;(3²)a + 3b + c = 4
9a + 3b + c = 4 ----(eq 1)
For coordinate (4, 0), the equation is;(4²)a + 4b + c = 0
16a + 4b + c = 0 ----(eq 2)
For coordinate (2, 0), the equation is;(2²)a + 2b + c = 0
4a + 2b + c = 0 ----(eq 3)
Solving the 3 equations using an online simultaneous equation solver tool, we have; a = -4; b = 24; c = -32Plugging these values of a, b and c into the general equation of parabola gives us;y = -4x² + 24x - 32
