Answer:
[tex]\sf \tan\left(c_2\right)=\dfrac{OD}{OC}=\dfrac{2\sqrt{66}}{19}[/tex]
Step-by-step explanation:
**Please note that if the segment AO = 3.8 cm then the 50° angle on the given rhombus is incorrect. It should be 49.46° (2 d.p.)**
In a rhombus, all four sides are equal in length. Therefore:
CD = AB = 5cmDiagonals bisect each other at 90°. Therefore:
OC = AO = 3.8 cmm∠COD = 90°Therefore, triangle COD is a right triangle.
To find the tangent ratio of angle c₂, first find the length of OD using Pythagoras Theorem:
[tex]\implies OC^2+OD^2=CD^2[/tex]
[tex]\implies 3.8^2+OD^2=5^2[/tex]
[tex]\implies 14.44+OD^2=25[/tex]
[tex]\implies OD^2=10.56[/tex]
[tex]\implies OD^2=\dfrac{1056}{100}[/tex]
[tex]\implies OD^2=\dfrac{1056 \div 4}{100 \div 4}[/tex]
[tex]\implies OD^2=\dfrac{264}{25}[/tex]
[tex]\implies OD^2=\dfrac{4 \cdot 66}{25}[/tex]
[tex]\implies OD=\sqrt{\dfrac{4 \cdot 66}{25}}[/tex]
[tex]\implies OD=\dfrac{\sqrt{4 \cdot 66}}{\sqrt{25}}[/tex]
[tex]\implies OD=\dfrac{2\sqrt{66}}{5}[/tex]
[tex]\boxed{\begin{minipage}{6 cm}\underline{Tan trigonometric ratio} \\\\$\sf \tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\end{minipage}}[/tex]
Given:
θ = c₂O = ODA = OCSubstitute the values into the tan ratio:
[tex]\implies \sf \tan\left(c_2\right)=\dfrac{OD}{OC}[/tex]
[tex]\implies \sf \tan\left(c_2\right)=\dfrac{\frac{2\sqrt{66}}{5}}{3.8}[/tex]
Rewrite 3.8 as 19/5:
[tex]\implies \sf \tan\left(c_2\right)=\dfrac{\frac{2\sqrt{66}}{5}}{\frac{19}{5}}[/tex]

find the length of the curve. r(t) = 6t i + 8t3/2 j + 6t2 k, 0 ≤ t ≤ 1
Answers
The length of the curve is given by the integral of the magnitude of the velocity vector, which is the derivative of the position vector. Taking the derivative of the position vector, we get the velocity vector as follows:
v(t) = 6i + 24t1/2j + 12tk
The magnitude of this vector is
√(6²+ 24²t + 12²t²)
= √(36 + 576t + 144t²).
To find the length of the curve, we need to integrate this magnitude from t=0 to t=1. This is given by the integral:
L = ∫0² √(36 + 576t + 144t²)dt
This evaluates to L = 18.75. Therefore, the length of the curve is 18.75.

find the perimeter of the triangle with the vertices $(0,\ 1),\ (3,\ 6)$ , and $(4,\ 1)$ . if necessary, round your answer to the nearest hundredth.
Answers
The perimeter of the triangle having vertices (0,1),(3,6), and (4,1) will be 10.83 units.
Any two-dimensional figure's perimeter is determined by the space surrounding it. By summing the lengths of the sides, we can determine the perimeter of any closed shape.
Any polygon's perimeter is equal to the sum of its side lengths. Considering a triangle
The sum of the three sides equals the perimeter.
Units are always a part of the ultimate response. The final solution should be given in centimeters if the triangle's sides are in that unit.
Because the y values between U and V differ, the distance is equal to the x value difference.
Because the x values of V and W differ, the distance equals the difference between their y values.
The hypotenuse of a right triangle, or U to W, equals sqr (sum of squares on the other two sides)
Perimeter = sum of the 3 sides
[tex]= \sqrt{34} + \sqrt{26}+ \sqrt{16}= 5.83 + 5.1 + 4 = 10.83\:units[/tex]

The total distances add up to the triangle's perimeter is 10.00
The triangle's perimeter may be calculated by summing the distances between its three vertices. Use the distance formula to calculate the separation between the points:
d = √((x2 - x1)2 + (y2 - y1)2)
The distances between the points are as a result for the triangle with vertices (0,1), (3,6), and (4,1)
Utilizing the distance formula, determine the separation between (0,1) and (3,6):
d = √((x2 - x1) 2 + (y2 - y1) 2) = √((3-0) 2 + (6-1) 2) = √(32 + 52) = √45
Utilizing the distance formula, determine the separation between (3,6) and (4,1):
d = √((x2 - x1) 2 + (y2 - y1) 2) = √((4-3) 2 + (1-6) 2) = √(12 + 52) = √25
Utilizing the distance formula, determine the separation between (4,1) and (0,1):
d = √((x2 - x1) 2 + (y2 - y1)2) = √((0-4) 2 + (1-1) 2) = √(42 + 02) = √16
The triangle's perimeter is calculated by adding the three distances together:
Perimeter = √45 + √25 + √16 = 10.00.
Hence, the perimeter of the triangle is 10.00, rounded to the closest hundredth.

Answers
It's worth noting that to solve for T2 you need to have the values of other variables such as K1, K2, Ea, R and T1
What is the Arrhenius Equation?
The Arrhenius equation is a mathematical equation that describes the relationship between the rate constant (K) of a chemical reaction and the temperature (T) of the reaction. The equation was first proposed by Svante Arrhenius in 1889 and it states that the rate constant of a chemical reaction is directly proportional to the exponential of the negative activation energy (Ea) of the reaction, divided by the gas constant (R) and the absolute temperature (T). The equation can be written as:
K = A * e^(-Ea / (R*T))
The Arrhenius Equation Two-point form is a mathematical equation that describes the relationship between the rate constant (K) of a chemical reaction, the activation energy (Ea) of the reaction, the universal gas constant (R), and the temperature (T) of the reaction.
Given the equation K2/K1 = Ea / R (1/T1 - 1/T2)
a. To solve for K2, we can multiply both sides of the equation by
K1: K2 = K1 * Ea / R (1/T1 - 1/T2)
b. To solve for K1, we can divide both sides of the equation by
Ea / R (1/T1 - 1/T2): K1 = K2 / Ea / R (1/T1 - 1/T2)
c. To solve for Ea, we can multiply both sides of the equation by
R (1/T1 - 1/T2): Ea = K2/K1 * R (1/T1 - 1/T2)
d. To solve for T2, we can use the equation 1/T2= 1/T1 - Ea/R * K1/K2
It's worth noting that to solve for T2 you need to have the values of other variables such as K1, K2, Ea, R and T1.

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of ducks be D
Let the number of cows be C
Now , the total number of animals = 14
So , D + C = 14 be equation (1)
And , the total number of legs = 40
Number of legs for ducks = 2 legs
Number of legs for cows = 4 legs
And , the total number of legs = 2D + 4C = 40
So , 2D + 4C = 40 be equation (2)
On simplifying the equations , we get
Multiply equation (1) by 2 , we get
2D + 2C = 28 be equation (3)
Subtracting equation (3) from equation (2) , we get
2C = 40 - 28
2C = 12
Divide by 12 on both sides of the equation , we get
C = 6 cows
Substituting the value of C in equation (1) , we get
D = 14 - 6
D = 8 ducks
Therefore , the value of C and D is 6 and 8 respectively

{ 0 otherwise.
a) Find the probability that the student finishes the inquiry in less than 1.5 hours.
b) Find the mean and standard deviation of the number of hours it takes to finish the inquiry.
Answers
The probability that the student finishes the inquiry in less than 1.5 hours is 0.45.
Mean= 4/3 and standard deviation= √(11/90)
a) To find the probability that the student finishes the inquiry in less than 1.5 hours, we need to find the area under the probability density function (PDF) of f(x) between the lower limit of 1 and the upper limit of 1.5.
This is given by the definite integral of f(x) from 1 to 1.5:
∫f(x)dx from 1 to 1.5
= ∫(2/5(x + 1))dx from 1 to 1.5
= (2/5)∫(x + 1)dx from 1 to 1.5
= (2/5)[x^2/2 + x] from 1 to 1.5
= (2/5)[(1.5)^2/2 + 1.5 - (1)^2/2 - 1]
= (2/5)[2.25/2 + 1.5 - 1/2 - 1]
=(2/5)[2.25/2]
=0.45
b) To find the mean, we need to use the formula:
Mean = ∫x*f(x)dx from a to b
In this case:
Mean = ∫x*(2/5(x + 1))dx from 1 to 2
= (2/5)∫x(x + 1)dx from 1 to 2
= (2/5)[x^3/3 + x^2/2] from 1 to 2
=(2/5)[(2)^3/3 + (2)^2/2 - (1)^3/3 - (1)^2/2]
= (2/5)[8/3 + 4/2 - 1/3 - 1/2]
=(2/5)[7/3 + 3/2]
=(2/5)[(20)/6]
=4/3
=1.333
To find the standard deviation, we need to use the formula:
Standard deviation^2 =(∫(x-μ)^2*f(x)dx) from a to b
Where μ is the mean
In this case,
Standard Deviation ^2= ∫(x-μ)^2(2/5)(x+1) dx from 1 to 2
=(2/5)∫(x-μ)^2(x+1) dx from 1 to 2
Simplifying, we get,
(x-μ)^3*(3x+μ+4)/30 from 1 to 2
=[(2-μ)^3*(6+μ+4)-(1-μ)^3*(3+μ+4)]/30
=[(2-μ)^3*(10+μ)-(1-μ)^3*(7+μ)]/30
Substituting the value of μ,
=[(2-4/3)^3*(10+4/3)-(1-4/3)^3*(7+4/3)]/30
=11/90
Therefore, Standard Deviation= √(11/90)

9 / 3 = 3
Box 2:
The bottom is multiplied by 1 ⅔, so you do the same to the bottom
1 ⅔ x 15 = 25

function f(x) = x² to transform the
function to g(x) = (x-4)² +2.
Answers
Answer:
4 units right, 2 units up
Step-by-step explanation:
For [tex]g(x)=(x-4)^2+2[/tex], the graph of [tex]f(x)=x^2[/tex] would need to move 4 units to the right and 2 units up. Hence, the vertex would be [tex](4,2)[/tex] if we compare the function g(x) with the form [tex]y=a(x-h)^2+k[/tex].
Can someone please solve this.

What is differential equation?A differential equation is an equation which contains one or more terms and the derivatives of one variable (i.e., dependent variable) with respect to the other variable (i.e., independent variable) dy/dx = f(x) Here “x” is an independent variable and “y” is a dependent variable. For example, dy/dx = 5x.General Differential Equations. Consider the equation y′=3x2, which is an example of a differential equation because it includes a derivative. There is a relationship between the variables x and y:y is an unknown function of x. Furthermore, the left-hand side of the equation is the derivative of y.Ordinary differential equations applications in real life are used to calculate the movement or flow of electricity, motion of an object to and fro like a pendulum, to explain thermodynamics concepts. Also, in medical terms, they are used to check the growth of diseases in graphical representationTo learn more about differential equation refers to:

If a rectangular garden is 45 ft. by 20 ft., how many feet of fence are needed to enclose it?
Answers
Answer:
130 feet
Step-by-step explanation:
45 feet is one of the lengths of the rectangular garden and 20 feet is the other.
The perimeter of a rectangle is 2(l+w) and we know that these must be the lengths and widths.
Communitive property of addition states that it doesn't matter the order that we add so we know it's just 20+45 (65) then times 2 which is 130
130 feet is your answer.
