What will be the solution of linear equation 3x 4y 10 and 2x 2y 2?.
Answers
The solutions of the system of linear equations 3x+ 4y= 10 2x+ 2y= 2 can be found by using the method of substitution or elimination.Solve one of the equations for one of the variables in terms of the other variable.
Let's solve the first equation for x: 3x + 4y = 10 3x = -4y + 10 x = -4/3y + 10/3
Substitute this expression into the other equation and solve for the remaining variable.
2(-4/3y + 10/3) + 2y = 2 -8/3y + 20/3 + 2y = 2 -8/3y + 2y = -20/3 + 2 -2/3y = -18/3 y = 9
Use the value of y to find the value of x.
x = -4/3y + 10/3 x = -4/3(9) + 10/3 x = -4 + 10/3 x = -4 + 10/3
The solution of the system of equations is (x,y) = (-4 + 10/3, 9)

The slope of this line is m = 1.
An equation of this line is y = x.
How to calculate the slope of a line?In Mathematics, the slope of any straight line can be determined by using this mathematical equation;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Based on the information provided, we can logically deduce the following data points on the line:
Points on x-axis = (0, 1).Points on y-axis = (0, 1).Substituting the given data points into the slope formula, we have the following;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (1 - 0)/(1 - 0)
Slope (m) = 1/1
Slope (m) = 1
At data point (1, 1), an equation of this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x and y represents the data points.y - 1 = 1(x - 1)

Answers
The slope of the line is a measure of the rate of change between two points and is calculated by dividing the change in y-values by the change in x-values. In this case, the slope is -6, which means that for every 1 unit increase in x, there is a 6 unit decrease in y.
The slope of the line is a measure of the rate of change between two points. It is calculated by dividing the change in y-values by the change in x-values. To find the slope of the line represented by the table of values, we need to first identify two points on the line. We will use the points (x1, y1) and
(x2, y2).
We can choose any two points, but for this example, we will use
(x1, y1) = (-7, 9) and (x2, y2) = (8, -15).
The slope of the line is then calculated by finding the difference between the y-values
(y2 - y1 = -15 - 9 = -24)
and the difference between the x-values
(x2 - x1 = 8 - (-7) = 15)
and dividing these two values:
-24/15 = -6.
This means that for every 1 unit increase in x, there is a 6 unit decrease in y.

It is a downward parabola, which means the height of the ramp decreases as the distance from one side of the ramp increases.
What is the parabola?
A parabola is a symmetric, U-shaped geometric curve that can be defined as the set of all points that are equidistant to a fixed point (the focus) and a fixed line (the directrix). It is a conic section, which means it is the intersection of a plane and a cone. In algebraic terms, a parabola can be defined as the graph of a quadratic equation of the form y = ax^2 + bx + c, where a, b, and c are constants.
The height of a ramp can be modeled by f(x) = -1/2 x − 241 +2, where f(x) is the height of the ramp, in feet, and x is the distance from one side of the ramp. To find the vertex of the parabola, we need to complete the square.

Answers
It would take Lisa 3 hours to complete the painting as both Brennan and Lisa could end up charging the same amount of $63.
What is an hour?An hour is a unit of time that is traditionally calculated as 124 of a day and is scientifically estimated to last between 3,599 and 3,601 seconds, depending on how quickly the Earth rotates. There are 60 minutes in an hour and 24 hours in a day.
The concept of the hour was first developed in the ancient Near East as a flexible measurement of 1/12 of the night or day. Such seasonal, temporal, or uneven hours varied with latitude.
Equal or equinoctial hours were defined as 124 of the day, measured from noon to noon; the minor seasonal variations of this unit were eventually smoothed out by making it 124 of the mean solar day.
Flat rate quoted by Brennan = $63
Rate quoted by Lisa = $8 h + $47
The number of hours for Lisa to finish the painting = ($63 - $47)/$8
= 2 hours
The total cost that Lisa would charge is = ($8 x 2 + $47)
= $63
Thus, It would take Lisa 3 hours to complete the painting as both Brennan and Lisa could end up charging the same amount of $63.

Find, correct to the nearest degree, the three angles of the triangle with the given vertices.
Answers
The three angles of the triangle can be found by using the formula for the sum of angles of a triangle, which is 180°. Then, the measure of angle A + angle B + angle C = 180°.
1. Using the sum of angles formula, angle A + angle B + angle C = 180°
2. Use the Law of Cosines to calculate the angle between two sides of the triangle.
3. Subtract the sum of those two angles from 180° to find the measure of the third angle.
The three angles of a triangle can be found using the sum of angles formula, which states that the sum of the angles of a triangle equals 180°. This means that angle A + angle B + angle C = 180°. To find the individual angles, we can use the Law of Cosines which states that c2 = a2 + b2 - 2ab cos C, where C is the angle between two sides of the triangle. This formula allows us to calculate the angle between two sides of the triangle. Once we have calculated the sum of the two angles, we can subtract this sum from 180° to find the measure of the third angle. For example, if the sum of the two angles is 120°, then the third angle would be 180° - 120° = 60°. This method allows us to find the three angles of the triangle with the given vertices.

what is wave Equation?One of the most crucial equations in mechanics is the wave equation. It describes the movement of fluid surfaces, such as water waves, in addition to the movement of strings and wires.
Define constants:
t0 = 1.7seconds h0 = 58cm highest point
t1 = 4.4 seconds h1 = 44 cm lowest point
t2 = 6 seconds h2 = (h0 + h1)/2 = 51 cm center height
Half a cycle passes between t0 and t1, so the period T is
T = 2(t1 - t0) = 2(4.4-1.7) seconds = 5.4 seconds
The amplitude A is half the total height change between h0 and h1:
A = (h0 - h1)/2 = 7 cm
a) Equation of motion in terms of height H above the floor is
H(t) = h2 + A Co s[2π(t - t0)/T]
H(t) = 51 cm + (7cm) Cos[0.1775(t - 1.7second)/second]
b) Let t = 6 seconds in the equation:
H(t) = 51 cm + (7cm) Cos[0.1775(6 - 1.7second)/second]
= 51 + 7 x (-0.4008)

A Cylinder The lateral surface of a cylinder has an area of 824 m². The cylinder has a height of 40 m. a) Determine the circumference of the cylinder's circular face.
Answers
The circumference of cylinder's circular face is 20.09 pi units.
What is circumference?The cylinder's lateral surface area is equal to the circumference of the circular base multiplied by the height. A circle's circumference is 2r and its height is h, so the lateral area is 2rh.
That is LSA = 2 × π × r × h where, r = base radius, and h = height of the cylinder.
Here given,
LSA = 824m²
Height = 40 m
By substituting
824 = 2 x 3.14 x r x 40
824 / 2 x 3.14 x 40 = r
r = 3.2m
Circumference of circular face = 2 π r
By substituting the values,
Circumference = 2 x 3.14 x 3.2
Circumference = 20.09 pi units.
Therefore the circumference of a cylinder with circular face is 20.09 pi units.

following is closest to the value of b?
Answers
The closest to the value of b is 3.6912.
An exponential function is a Mathematical function in the form f (x) = ax, where “x” is a variable and “a” is a constant which is called the base of the function and it should be greater than 0. The most commonly used exponential function base is the transcendental number e, which is approximately equal to 2.71828.
f(x)=a(b)^x and we know that f(3)=17 and f(7)=3156. what is the value of b
Set up both equations with values
When x = 3, f(3) = 17, so we have a(b)^3 = 17
When x = 7, f(7) = 3156, so we have a(b)^7 = 3156
Isolate a in each equation
a = 17/(b)^3
a = 3156/(b)^7
Now set them equal to each other
17/(b)^3 = 3156/(b)^7
Cross Multiply
17b^7 = 3156b^3
Divide each side by b^3
17b^4 = 3156
Divide each side by 17
b^4 = 185.6471
b = 3.6912
Therefore, the closest to the value of b is 3.6912.
