The measure of angle fge is 53.13°.
The equation used to find the measure of angle fge is the Law of Cosines. The Law of Cosines states that for any triangle, the square of the length of any side is equal to the sum of the squares of the other two sides, minus twice the product of those sides and the cosine of the angle opposite the side.
Using the Law of Cosines, we can solve for the measure of angle fge as follows:
[tex]fge = cos-1((a^2 + b^2 - c^2) / 2ab)[/tex]
For example, if the length of side a is 3, the length of side b is 4, and the length of side c is 5, then the measure of angle fge can be calculated as follows:
fge =[tex]cos-1((3^2 + 4^2 - 5^2) / 2(3)(4))[/tex]
fge = [tex]cos-1(1/6)[/tex]
fge = 53.13°
Therefore, the measure of angle fge is 53.13°.

Answer:
122
Step-by-step explanation:
the question is asking for the area of the whole shape
however, it's split into a trapezoid and rectangle, so all you have to do is find the area of the respective shapes and then add them
the formula for area of a rectangle is [tex]A = L(W)[/tex]
if you substitue, A = 15(6)
so the area of the rectangle is 90
then, you have the trapezoid
area of a trapezoid = [tex]\frac{1}{2} (h)(b_{1} +b_{2})[/tex]
you might assume that you don't have the second base, but it's in the rectangle - 6
A = 1/2(4)(6+10)
A=32
90+32 = 122

Camden went to the grocery store and purchased cans of soup and frozen
dinners. Each can of soup has 150 mg of sodium and each frozen dinner has
300 mg of sodium. Camden purchased a total of 7 cans of soup and frozen
dinners which collectively contain 1500 mg of sodium. Graphically solve a
system of equations in order to determine the number of cans of soup
purchased, x, and the number of frozen dinners purchased, y.
Camden purchased 4 cans of soup and 3 frozen dinners.
How to solve for thisWe can solve this problem by using a system of two linear equations.
Let x be the number of cans of soup purchased and y be the number of frozen dinners purchased.
Then, based on the information given, we can set up two equations as follows:
150x + 300y = 1500 (the total amount of sodium consumed is 1500 mg)
x + y = 7 (Camden purchased 7 cans of soup and frozen dinners)
Now, we can use either substitution or elimination to find the values of x and y.
Using substitution:
Solve the second equation for y: y = 7 - x
Substitute the expression for y into the first equation: 150x + 300(7 - x) = 1500
Simplify the expression: 150x + 2100 - 300x = 1500
Combine like terms: -150x + 2100 = 1500
Solve for x: -150x = -600
Divide both sides by -150: x = 4
Use the second equation to find y: y = 7 - x = 7 - 4 = 3
So, Camden purchased 4 cans of soup and 3 frozen dinners.

y=x-6 and y=-x-2 graph the system then right a solution if there is one
Answer: To graph the system of linear equations, you can plot the two lines on the same coordinate plane and look for the point where they intersect. If they intersect, that point represents the solution to the system.
The equation y = x - 6 can be written in slope-intercept form, y = mx + b, where m = 1 and b = -6. The equation of the line will be y = x - 6.
The equation y = -x - 2 can be written in slope-intercept form, y = mx + b, where m = -1 and b = -2. The equation of the line will be y = -x - 2.
Plotting these two lines on the same coordinate plane, we can see that they intersect at the point (2, -4). This means that there is one solution to the system of equations: (2, -4).

what's the domain and range of the function f(x) = 5(4)^x + 2
The required domain and range of the function are (-∞, ∞) and (2, ∞).
How to find the domain and range of the function?The domain of a function is the set of all possible values of the input variable (x) for which the function is defined. In this case, the function is an exponential function with base 4, which means it is defined for all real numbers.
Therefore, the domain of f(x) is all real numbers, or (-∞, ∞).
The range of a function is the set of all possible values of the output variable (f(x)) for all possible values of the input variable (x).
Since 4^x is always positive (for all x), the value of the function f(x) will always be greater than 2 (the constant added to 5(4)^x), no matter what the value of x is.
As x approaches negative infinity, 5(4)^x approaches zero, so the minimum value of f(x) is 2.
As x approaches positive infinity, 5(4)^x increases without bound, so the range of f(x) is (2, ∞).
Thus, required domain and range of the function are (-∞, ∞) and (2, ∞).

What is a monomial example?
A monomial is an algebraic expression that consists of a single term. A monomial can contain constants and/or variables, which are multiplied together.
The expression 3x²y is a monomial. It contains the constant 3, the variable x squared, and the variable y. The variables can be raised to an exponent, as in this example; however, the exponent must be a whole number.A monomial can also contain coefficients, which are the numbers that are multiplied with a variable. In the example above, the coefficient is 3. If there is no coefficient stated, then the coefficient is assumed to be 1. Therefore, the expression x²y is also a monomial, with the coefficient being 1.Additionally, a monomial can contain a product of numbers and variables, such as the expression 2xyz. This is also considered a single term, since all of the numbers and variables are multiplied together.
Monomials can be used to calculate polynomials, which are algebraic expressions consisting of multiple terms. By adding, subtracting, and multiplying monomials together, you can create a polynomial. For example, the expression (3x²y) + (2xyz) is a polynomial, since it consists of two terms. The first term is the monomial 3x²y, and the second term is the monomial 2xyz.

C is the circumcenter of isosceles triangle ABD with vertex angle ∠ABD. Does the following proof correctly justify that triangles ABE and DBE are congruent?
It is given that triangle ABD is an isosceles triangle, so segments AB and DB are congruent by the definition of isosceles triangle.
It is given that C is the circumcenter of triangle ABD, making segment BE a median.
By the definition of perpendicular, angles AEB and DEB are 90°, so triangles ABE and DEB are right triangles.
Triangles ABE and DEB share side BE making it congruent to itself by the reflexive property.
Triangles ABE and DBE are congruent by HL.
Triangle ABD with segments BC, DC, and AC drawn from each vertex and meeting at point C inside triangle ABD, segment BC is extended past C with dashed lines so that it intersects with side AD at point E.
There is an error in line 1; segments AB and BD are given to be congruent.
There is an error in line 2; segment BE should be a perpendicular bisector.
There is an error in line 4; segment BE is not a shared side.
The proof is correct.
The proof is not correct.
How did we arrive at this assertion?The given information that segments AB and BD are congruent does not imply that triangles ABE and DBE are congruent. Congruency of triangles requires more information, such as additional side lengths or angle measures.
While it is true that point C is the circumcenter of triangle ABD and that segment BE is a median, it is not necessarily true that BE is also a perpendicular bisector. In fact, this would only be true if triangle ABD were also an equilateral triangle.
The statement that triangles ABE and DEB share side BE is incorrect. Triangles ABE and DEB do not share any sides, but rather have segment BE as a common hypotenuse.
Therefore, the conclusion that triangles ABE and DBE are congruent by HL (hypotenuse-leg) is not valid since the previous steps in the proof are flawed.

Slope: [tex]\bf \boxed{-\dfrac{1}{3}}[/tex]
y-intercept: [tex]\boxed{-1}[/tex]
Equation: [tex]\boxed{\bf{y=-\dfrac{1}{3}x - 1}}[/tex]
The two boxes at the bottom are asking you to repeat the above information:
the slope is [tex]\bf \boxed{-\dfrac{1}{3}}[/tex] the y-intercept is [tex]\boxed{-1}[/tex]
Step-by-step explanation:
Actually, you don't have to graph the equation since the graph is already provided
You have to answer the questions based on the provided graph
To find slope
1. Take any two well=defined points on the graph:
We can see that point (0, -1) which has x value at 0 and y-value 1 unit down is a distinguishable point. Let's call this point P1Another point is (3, -2). Let's call this point P22. Find the difference in y-values between P2 - P1. This called rise
rise = P2 v-value - P1 y-value = -2 - (-1) = -2 + 1 = - 1
3. Find the corresponding difference in x-values: P2 - P. This is called run
4. The slope is computed as rise/run = - 1/3
To find y-intercept
Just note where the line crosses the y-axis and the y-value corresponding to that would be the y-intercept
This is also the y-value at which x = 0
Looking at the graph we see that the line crosses(intercepts) the y-axis at y = - 1
So y-intercept = - 1
To write the equation
The equation of the line is
y = mx + b
where
m = slope
b = y-intercept
So the equation of this particular line is

k = 20/30 = 2/3
The equation becomes
y = 2/3 x
Therefore if x = 1 we get
y = 2/3 x 1 = 2/3

For the SOLVED version: j = 4037.
Multiply 11 on both sides, canceling the 11 on one side and getting 4037 when you multiply 11 by 367.
Answer:
J/11 = 367; this is the equation as When J is divided by 11 it answers to 367
Step-by-step explanation:
total answer;
J = 367(11)
J= 4037
