4. The value of y is directly proportional to the value of x. If y = 45 when x = 180, what is the value of y when x = 80?
Given:
The value of y is directly proportional to the value of x.
y = 45 when x = 180.
To find:
The value of y when x = 80.
Solution:
Since the value of y is directly proportional to the value of x, therefore
[tex]y\propto x[/tex]
[tex]y=kx[/tex] ...(i)
where, k is constant of proportionality.
Putting y=45 and x=180, we get
[tex](45)=k(180)[/tex]
[tex]\dfrac{45}{180}=k[/tex]
[tex]k=\dfrac{1}{4}[/tex]
Substituting [tex]k=\dfrac{1}{4}[/tex] in (i), we get
[tex]y=\dfrac{1}{4}x[/tex]
Put x=80 in this equation.
[tex]y=\dfrac{1}{4}(80)[/tex]
[tex]y=20[/tex]
Therefore, the value of y is 20 when x=80.

Robert is designing hexagonal tiles that are made up of 12 identical right triangles, as shown. Write three equations robert can use the find the area A of the hexagonal tile in square centimeters.
Given:- Hexagon is made up of identical 12 triangles Sides of triangle :- 5cm,4cm,3cmTo Find:- 3 Equations for finding the area of the triangle Answer:-First method:-we know 12 triangles make up hexagon so we can say
12× Area of triangle = Area of hexagon
[tex]12 \times ( \frac{1}{2} \times base \times height) = area \: of \: hexagon[/tex]
[tex]12 \times \frac{1}{2} \times 3 \times 4 = area \: of \: hexagon \\ 12 \times 3 \times 2 = area \: of \: hexagon \\ 12 \times 6 = area \: of \: hexagon \\ 72cm {}^{2} = area \: of \: hexagon[/tex]
Second method:-we can see that there is a rectangle in the middle of the hexagon and 4 triangles (identical ) on 2 sides
According to question:-
sides of rectangle :- 8 cm and 6cmside of triangle is sameso area of hexagon= area of square+ 4 area of triangle
[tex]( l \times b ) + (4( \frac{1}{2} \times b \times h)) = area \: of \: hexagon[/tex]
[tex] (8 \times 6 ) + 4(\frac{1}{2} \times 4 \times 3) = area \: of \: hexagon \\ 48 + 24= area \: of \: hexagon \\ 72 {cm}^{2} = area \: of \: hexagon[/tex]
Third method:-we can see 2 square at the sides of the 4 triangle at the middle so we can say
side of square = 5cmsides of triangle = 4cm ,3cmArea of hexagon =4× area of triangle + 2 area of square
[tex]area \: of \: hexagon = (4\frac{1 }{2} × 4×3)+2(5×5) [/tex]
[tex]area \: of \: hexagon = 24+ 50 \\ area \: of \: hexagon = 74cm² \\ area \: of \: hexagon = 72 cm ² approx [/tex]
This approximation turn out bez in your question the area of 4 identical triangle is not equal to square formed by them
4 area of triangle = area of square
4×6 = 24 cm² not equal to 5² = 25 cm²
thats why there is approximation of 2 cm²

Answer:
∠3 = 115°
Step-by-step explanation:
Angles 4 and 6 are "same-side interior angles", so are supplementary.
∠4 +∠6 = 180°
(x +5) +(2x -5) = 180
3x = 180
x = 60
The angles marked 3 and 6 are alternate interior angles, so are congruent. The measure of angle 3 is ...
∠3 = ∠6 = (2x -5)° = (2(60) -5)°
∠3 = 115°

The length of the arc is about 1.758 cm.
First, we need to determine the size of the angle. If we have pi/5 radians, we can convert that to 36 degrees, because pi radians is 180 degrees. Now, we know the measure of the arc is 36 degrees. 36 degrees out of 360 degrees is 10%.
Our arc is 10% of the circumference of the circle.
The circumference is 2(pi)r or 2(3.14)2.8 = 17.58 cm
Now, multiply 17.58 by 0.1 to get a total of 1.758 cm.

To rewrite y(t) = 2 * sin (4 pi t) + 5 * cos (4 pi t) in the form Asin(wt+phi), you must first find the amplitude. Use c1=Asin(phi) and c2=Acos(phi) along with the Pythagorean identity to solve for A (amplitude.) previous question: By plugging in for c1 and c2, the equation should shift to be: Asin(wt+phi)=Acos(phi)sin(wt)+Asin(phi)cos(wt) Use the identity sin(x+y)=sin(x)cos(y)+cos(x)sin(y)
Answer:
The equation in standard form is [tex]y(t) = 5.390\cdot \sin (4\pi\cdot t +0.379\pi)[/tex].
Step-by-step explanation:
We use the following trigonometric identity:
[tex]\sin (\alpha + \beta) = \sin \alpha\cdot \cos \beta + \cos \alpha \cdot \sin \beta[/tex], [tex]\forall\,\alpha,\beta\in \mathbb{R}[/tex] (Eq. 1)
If we have formula [tex]y(t) = 2\cdot \sin (4\pi\cdot t)+5\cdot \cos (4\pi\cdot t)[/tex], by direct comparison with (Eq. 1):
[tex]A\cdot \cos \phi = 2[/tex] (Eq. 2)
[tex]A\cdot \sin \phi = 5[/tex] (Eq. 3)
Where:
[tex]A[/tex] - Amplitude, dimensionless.
[tex]\phi[/tex] - Phase angle, measured in radians.
By dividing (Eq. 3) by (Eq. 2), we get that:
[tex]\tan\phi = \frac{5}{2}[/tex]
[tex]\phi = \tan^{-1}\left(\frac{5}{2} \right)[/tex]
[tex]\phi = 0.379\pi\,rad[/tex]
From (Eq. 2) we find the amplitude:
[tex]A = \frac{2}{\cos \phi}[/tex]
[tex]A = \frac{2}{\cos 0.379\pi}[/tex]
[tex]A = 5.390[/tex]
Therefore, we find that equation in standard form is:
[tex]y(t) = A\cdot \sin (\omega\cdot t +\phi)[/tex] (Eq. 4)
Where [tex]\omega[/tex] is the angular frequency, measured in radians per second.
([tex]A = 5.390[/tex], [tex]\omega = 4\pi\,\frac{rad}{s}[/tex], [tex]\phi = 0.379\pi\,rad[/tex])
[tex]y(t) = 5.390\cdot \sin (4\pi\cdot t +0.379\pi)[/tex]
Tom started an entertainment company.

Answer:
4(t-3)^2-64
3 months
Step-by-step explanation:
1) Vertex form of the equation of the parabola is [tex]v(t)=4(t-3)^2-64[/tex]
2)3 months after its creation the company will reach its lowest net value.
The net value of the company after t months is given as:
[tex]v(t) = 4t^2-24t-28[/tex]
The above parabolic equation can be written as
[tex]v(t)=4(t^2-6t+9)-64[/tex]........(1)
What is the general equation of a parabola with vertex (h,k)?The general equation of a parabola is:
[tex]y = a(x-h)^2 +k[/tex]
where (h,k) is the vertex of the parabola.
So, (1) can be written in the vertex form as
[tex]v(t)=4(t-3)^2-64[/tex]
So, the vertex of the given parabola is (3, -64).
[tex]v'(t) = 8t - 24[/tex]
[tex]v''(t) =8[/tex]
So, from the second derivative test
t value corresponding to v'(t) =0 will give minimum value
[tex]8t-24=0[/tex]
[tex]t=3[/tex]
So, 3 months after its creation the company will reach its lowest net value.
Therefore, 1) Vertex form of the equation of the parabola is [tex]v(t)=4(t-3)^2-64[/tex]
2)3 months after its creation the company will reach its lowest net value.

Solve this equation. Enter your answer in the box. –4(x – 26) = –200\
Answer:
x is 76
Step-by-step explanation:
im pretty sure, i just sloved it
Answer:
76.
Step-by-step explanation:
Simplifying
-4(x + -26) = -200
Reorder the terms:
-4(-26 + x) = -200
(-26 * -4 + x * -4) = -200
(104 + -4x) = -200
Solving
104 + -4x = -200
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-104' to each side of the equation.
104 + -104 + -4x = -200 + -104
Combine like terms: 104 + -104 = 0
0 + -4x = -200 + -104
-4x = -200 + -104
Combine like terms: -200 + -104 = -304
-4x = -304
Divide each side by '-4'.
x = 76
Simplifying

The difference of two number is 2 and product of them is 224. Find the Numbers if both of them are negative.
Answer:
The numbers are 14 and 16.
Step-by-step explanation:
Equation:
x (x - 2) = 224
Solution:
x (x - 2) = 224
x² - 2x = 224
x² - 2x - 224 = 0
Now, we ended up with a trinomial. To find the two numbers, we need to factor it.
Factoring Trinomials
Trinomial is a polynomial with three terms which are connected by plus or minus notations. It is expressed as a² + b + c.
To factor, we need to follow these steps:
1. Find the factors of "ac" that when combined it will result to "b".
2. When "c" is positive, the sign in each binomial is the same as "b".
3. When "c" is negative, the sign in each binomial is different.
4. Write as the product of two binomials ( )( ).
Let us continue.
x² - 2x - 224
(x - 16)(x + 14)
Therefore, x = 16 and x = -14.
Since we are looking for a positive value, we are going to use the positive value of x and that is 16.
Larger number is 16.
x - 2 = 16 - 2 = 14
Smaller number is 14.
Final Answer:
The two numbers are 14 and 16.
Checking:
x (x - 2) = 224
16 (16 - 2) = 224
16 (14) = 224
224 = 224 ✔

Mean = 11Step-by-step explanation:
The mean is the average number of the data.
Given data: 17, 9, 11, and 7To calculate the mean of the data, divide the sum of the data by the total numbers in the data. The quotient will be the average of the data.
[tex]\dfrac{17 + 9 + 11 + 7}{\text{Total digits in the data}}[/tex]
We can see 4 digits included in the data. Thus, the sum of the data will be divided by 4.
[tex]\dfrac{17 + 9 + 11 + 7}{4}[/tex]
Now, let's solve for the mean.
[tex]\dfrac{17 + 20 + 7}{4}[/tex]
[tex]\dfrac{44}{4} = 11[/tex]
