Step-by-step explanation:
\(m\angle CBF = 46\degree\) (Given)
\(m\angle FIG = 55\degree\) (Given)
\(m\angle IFG = m\angle CBF\) (Corresponding angles)
\(\implies m\angle IFG = 46\degree\)
\(m\angle FGC =m\angle IFG+ m\angle FIG\)
(By exterior angle theorem)
\(m\angle FGC =46\degree+ 55\degree \)
\(m\angle FGC =101\degree\)

Round answers to 3 decimals or more. Absolute Maximum: 21.243 Absolute Minimum: 12.757 X
The absolute maximum value of the function f(x, y) = 2x² + 2y² + x + y - 1 on the domain x² + y² ≤ 9 is 21.243, and the absolute minimum value is 12.757.
To find the absolute extrema of the given function on the given domain, we can use the method of Lagrange multipliers. First, we define the objective function as f(x, y) = 2x² + 2y² + x + y - 1, and the constraint function as g(x, y) = x² + y² - 9.
Next, we calculate the partial derivatives of the objective function with respect to x and y, as well as the partial derivatives of the constraint function with respect to x and y. Setting up the Lagrange equations, we have:
∇f(x, y) = λ∇g(x, y)
where ∇ represents the gradient operator and λ is the Lagrange multiplier. Solving these equations simultaneously, we obtain values for x, y, and λ.
By substituting the obtained values of x and y into the objective function f(x, y), we can calculate the corresponding function values. The maximum value among these function values represents the absolute maximum, and the minimum value represents the absolute minimum on the given domain.
Rounding the results to three decimal places, we find that the absolute maximum is 21.243, and the absolute minimum is 12.757. These values indicate the highest and lowest points, respectively, that the function achieves on the given domain.

How do you find the y-intercept with two ordered pairs?
Equation employing the slope-intercept method for two points
The slope-intercept version of the equation may be used to calculate the two-point Y-intercept.
The shape of a point-slope is\(\mathbf{Y-Y_{1} = m(X-X_{1})}.\)
Steps to find the y-intercept with two ordered pairs?
Determine the slope using two points.
\(Slope = \frac{Y_{2}-Y_{1}}{X_{2}-X_{1}} = \frac{Rise}{Run} = \frac{\bigtriangleup Y}{\bigtriangleup X}\)
As an illustration, two points are (3, 5) and (6, 11)
Slope = \(\frac{Y_{2}-Y_{1}}{X_{2}-X_{1}} = \frac{11 - 5}{6 - 3} = \frac{6}{3} = 2\)
In the slope-intercept form of the equation, substitute the slope(m).
\(\\y = mx+b \\y = 2x+b\)
Either point may be substituted in the equation. You may either use (3,5) or (6,11).
\(\\y = 2x+b \\5 = 2(3)+b\)
Find the answer to the equation for b, the line's y-intercept.
\(\\5 \ \ \ = 2(3) + b \\5 \ \ \ = 6 + b \\\underline{-6\ = -6 \ \ \ \ \ \ \ } \\-1 = b\)
Substitute b, into the equation.
\(\\y = 2x + b \\y = 2x - 1\)

3. The system of equations for two liquid surge tanks in series is
A₁ dh'₁/dt = q'ᵢ - 1/R₁ h'₁, q'₁ = 1/R₁ h'₁
A₂ dh'₂/dt = 1/R₁ h'₁ - 1/R₂ h'₂ q'₂ = 1/R₂ h'₂
Using state-space notation, determine the matrices A,B,C, and D assuming that the level deviations are the state variables: h'₁ and h'₂. The input variable is q'ᵢ , and the output variable is the flow rate deviation, q'₂.
The surge tank is a vital component of a system in which the flow rate fluctuates significantly. The flow rate entering the tank varies significantly, causing the fluid level in the tank to fluctuate as a result of the compressibility of the liquid. The surge tank is utilized to reduce pressure variations generated by a rapidly fluctspace uating pump flow rate. To determine the matrices A,B,C, and D using state-space notation, here are the steps:State representation is given by:dx/dt = Ax + Bu; y = Cx + DuWhere: x represents the state variablesA represents the state matrixB represents the input matrixC represents the output matrixD represents the direct transmission matrixThe equation can be written asA = [ -1/R₁ 0; 1/R₁ -1/R₂]B = [1/A₁; 0]C = [0 1/R₂]D = 0Thus, the matrices A,B,C and D assuming that the level deviations are the state variables: h'₁ and h'₂. The input variable is q'ᵢ, and the output variable is the flow rate deviation, q'₂ are given by A = [ -1/R₁ 0; 1/R₁ -1/R₂]B = [1/A₁; 0]C = [0 1/R₂]D = 0.Hence, the required matrices are A = [ -1/R₁ 0; 1/R₁ -1/R₂], B = [1/A₁; 0], C = [0 1/R₂], and D = 0 using state-space notation for the given system of equations for two liquid surge tanks.

F(x) 5.5 7 8.5
(x) 0 2 4
F(x) 2 5 9
The first function is a linear function while the second function is neither a linear nor exponential
How to identify whether a function is linear, exponential, or neither?
A linear function is of the form f(x) = mx + c,
where m is the slope (or rate of change) and y-intercept
m = y2-y1 / x2-x1
An exponential function is of the form f(x) = abˣ
where a and b are constants
In a linear function, the slope must be constant. Also, in exponential function a and b must be constants
Given:
(x) 2 3 4
F(x) 5.5 7 8.5
For x = 2 and 3:
slope = 7-5.5 / 3-2 = 1.5
For x = 3 and 4:
slope = 8.5-7 / 4-3 = 1.5
The slope is the same, thus, it is a linear function
Note: f(x) = y
(x) 0 2 4
F(x) 2 5 9
This is not linear, check for exponential
y = abˣ
when x = 0, y =2
2 = ab⁰
a = 2
when x =2, y = 5
5 = 2b²
b² = 5/2
b = √(5/2)
when x =4, y = 9
9 = 2b⁴
b⁴ = 9/2
b = \(\sqrt[4]{(9/2)}\)
Since the b are not the same. Thus, this is an exponential function also

How to find a quadratic equation with y-intercept and vertex? Explain with examples.
To find a quadratic equation with the y-intercept and vertex, follow these steps: identify the coordinates of the y-intercept and vertex, substitute them into the general form of the quadratic equation, solve for the coefficients, and substitute the coefficients back into the equation. For example, if the y-intercept is (0, 3) and the vertex is (-2, 1), the quadratic equation would be y = x^2 + x + 3.
To find a quadratic equation with the y-intercept and vertex, we can follow these steps:
Step 1: Identify the coordinates of the y-intercept. The y-intercept has the form (0, c), where c is the y-coordinate.Step 2: Identify the coordinates of the vertex. The vertex has the form (-b/2a, f(-b/2a)), where a, b, and c are the coefficients of the quadratic equation.Step 3: Substitute the coordinates of the y-intercept and vertex into the general form of the quadratic equation, y = ax^2 + bx + c.Step 4: Solve the resulting system of equations to find the values of a, b, and c.Step 5: Substitute the values of a, b, and c back into the general form of the quadratic equation to obtain the final equation.For example, let's say the y-intercept is (0, 3) and the vertex is (-2, 1). We can substitute these coordinates into the general form of the quadratic equation:
3 = a(0)^2 + b(0) + c
1 = a(-2)^2 + b(-2) + c
Simplifying these equations, we get:
c = 3
4a - 2b + c = 1
By substituting c = 3 into the second equation, we can solve for a and b:
4a - 2b + 3 = 1
4a - 2b = -2
2a - b = -1
By solving this system of equations, we find a = 1 and b = 1. Substituting these values back into the general form of the quadratic equation, we obtain the final equation:
y = x^2 + x + 3

To find a quadratic equation with a given y-intercept and vertex, you need the coordinates of the vertex and one additional point on the curve.
Start with the standard form of a quadratic equation: y = ax^2 + bx + c, where a, b, and c are constants.Use the vertex form of a quadratic equation: y = a(x - h)^2 + k, where (h, k) represents the coordinates of the vertex.Substitute the vertex coordinates (h, k) into the equation to obtain the equation in vertex form.Use the y-intercept to find another point on the curve. The y-intercept has the form (0, c), where c is the value of y when x is zero.Substitute the coordinates of the additional point into the equation to obtain a system of two equations. Solve the system to find the values of a, b, and c.Substitute the determined values of a, b, and c into the standard form of the quadratic equation to obtain the final equation.Example:
Suppose we want to find a quadratic equation with a y-intercept of (0, 4) and a vertex at (2, -1).
Using the vertex form, we have y = a(x - 2)^2 - 1.Substituting the y-intercept coordinates, we get 4 = a(0 - 2)^2 - 1, which simplifies to 4 = 4a - 1.Solving the equation above, we find a = 1.Substituting the values of a and the vertex coordinates into the vertex form equation, we have y = 1(x - 2)^2 - 1.Expanding the equation and simplifying, we get y = x^2 - 4x + 3.The final quadratic equation with the given y-intercept and vertex is y = x^2 - 4x + 3.To find a quadratic equation with a given y-intercept and vertex, you can use the vertex form of a quadratic equation and substitute the coordinates to obtain the equation. Then, use the y-intercept to find an additional point on the curve and solve a system of equations to determine the coefficients. Finally, substitute the coefficients into the standard form of the quadratic equation to get the final equation.

Find the 8th term of the geometric sequence 4,-12,36
The 8th term of the geometric sequence \(4,-12, 36\) is \(-8748\).
How to find the 8th term of the geometric sequence?We must find common ratio by dividing the term by its preceding term. By dividing second term (-12) by the first term (4), this gives us:
= -12 / 4
= -3
So, the common ratio is -3.
The formula for the nth term of geometric sequence to find the 8th term is : an = a1 * r^(n-1) where an = nth term, a1 = first term, r = common ratio and n = term number
a8 = 4 * (-3)^(8-1)
a8 = 4 * (-3)^7
a8 = 4 * (-2187)
a8 = -8748.
