List the angles of the triangle in order from largest to smallest.Question options:A) ∠A, ∠C, ∠BB) ∠C, ∠B, ∠AC) ∠B, ∠C, ∠AD) ∠A, ∠B, ∠C
Angles opposite to shorter sides are shorter. Then, the shortest angle is opposed to the shortest side.
Since the shortest side has a length 2.8 and is opposed to the angle A, then the shortes angle is A.
The next shortest side is that opposite to B, which has a length of 3.4.
And finally, the largest side has a length of 4.7 and it's opposite to the angle C.
Therefore, the list of angles from largest to smallest, is:
[tex]\angle C,\angle B,\angle A[/tex]Write a situation in which positive and negative numbers are used to describe values that have opposite meaning. What does 0 represent in this situation you created? (10 points)
A situation in which positive and negative numbers are used to describe values that have opposite meaning is that John is on top of a mountain that is 2000 above sea level and his friend is diving and is below 2000 feet.
The thing that 0 represents is the addition in the sea level.
How to illustrate the information?Based on the information illustrated, the situation will be that John is on top of a mountain that is 2000 above sea level and his friend is diving and is below 2000 feet.
Therefore, the addition will be:
= 2000 + (-2000)
= 2000 - 2000

She put the pieces together to form a parallelogram. What is the area of the parallelogram?
The area of the parallelogram is 240 feet.
What is area of parallelogram?A parallelogram's area is the area that it occupies in a two-dimensional plane. A parallelogram is a four-sided, two-dimensional form in geometry. This particular quadrilateral example has equal and parallel opposite sides. The space bounded by a parallelogram's four sides is known as its area. A parallelogram's area is determined by multiplying its length by its height.
A quadrilateral's interior angles add up to 360 degrees.
The area of a parallelogram can thus be written as :
Area = Base × Height
In this diagram it is given that the Base = 20 feet and the height = 12 feet
Thus the area can be obtained by simply multiplying these two dimensions
So area = 20 × 12 = 240 feet .

b(x)=18-0.5x 6 and 18
The solution of B(x) = 18 - 0.5x with x being -2, 0, 5 is 19, 18 and 15.5.
How to evaluate functions?Finding the value of f(x) =... or y =... that corresponds to a certain value of x is what it means to evaluate a function. Simply swap out all instances of x with the value of x to do this. For example, if we are requested to evaluate f(4), then the value 4 has been given to x.Given:
B(x) = 18-0.5x
x = -2, 0, 5
Putting the values of x to find the result of the function.
B(-2) = 18 - 0.5 × (-2) = 18 + 1 = 19
The required solution of the function at x = -2 is f(-2) = 19.
B(0) = 18 - 0.5 × (0) = 18
The required solution of the function at x = 0 is f(0) = 18.
B(5) = 18 - 0.5 × (5) = 18 - 2.5 = 15.5
Thus, the required solution of the function at x = 5 is f(5) = 15.5.

The property that completes the proof is the transitive property
How to determine the statement that represents the reason in the proof?From the question, we have the following parameters
The point C is the midpoint of AE
BC = CD
The above implies that
AC = CE
And it also means that:
The line segment BC and the line segment CD have equal lengths
According to the transitive property of equation, we have:
If A = B and B = C, then A = C
This can also be represented as
If A + B = C + D and C + D = E + F, then A + B = E + F
Using the above as a guide, we have (in step 3)
AB + BC = AC
CD + DE = CE

In the other words, there is the only one plane that contains that triangle, and every triangle is contained in some plane. If the entire geometry is only Euclidean plane, there is only one plane and all triangles are contained in it; however, in the higher-dimensional Euclidean spaces, this is no longer true.

The value of f'(x) at x = 1 is 1 for first order derivative of x^x^3.
A derivative in calculus is the rate of change of a quantity y with respect to another quantity x. It is also termed the differential coefficient of y with respect to x. Differentiation is the process of finding the derivative of a function.
Given that, x^x^3 and we have to find the first order derivative with respect to x and then find the value at x = 1.
Let's proceed to solve this question accordingly.
let f(x) = x^x^3
The first order derivative = f'(x) = d/dx(x^x^3)
First apply the generalized power rule, then we have
= x^x^3.d/dx(ln(x)x^3)
Applying the power rule, we get
= x^x^3 (d/dx(x^3).ln(x)+x^3.d/dx(ln(x)))
= x^x^3 (3x^2 ln(x) +x^3.1/x)
= x^x^3 (3x^2ln(x) +x^2)
On simplifying, we will get
= x^x^3+2(3ln(x)+1)
f'(x) = d/dx(x^x^3) = x^x^3+2(3ln(x)+1)
Now, at x = 1, we get
f'(x) = d/dx(x^x^3) = x^x^3+2(3ln(x)+1) = 1
Therefore, f'(x) = d/dx(x^x^3) = x^x^3+2(3ln(x)+1) = 1 is the required answer.

containing 46 that are defective and 26 that have no defects. What is the
probability that all four of the
calculators selected are defective? Round to four
decimal places.
A) 0.1021
B) 0.1586
C) 0.1666
D) 10.9154
Answer:
C) 0.1666
Step-by-step explanation:
The probability of selecting a calculator that is defective can be defined as: [tex]\frac{46}{46+26}[/tex]
The 46 in the numerator is the number of calculators that are defective in the group. The 46 + 26 represents the total amount of calculators since 46 are defective and 26 are not defective and assuming a calculator can only be defective or not defective then these are the total number of calculators in the group.
This gives you a probability of approximately: [tex]\frac{46}{72}[/tex] or approximately 0.638889
We can multiply independent events to find the combined probability of these events occurring. So we have to assume you put the calculator back into group after selecting one.
If this is the case we simply multiply 46/72 * 46/72 * 46/72 * 46/72 or (46/72)^4 to get an approximate probability of: 0.1666

To find the midpoint, plug the given points into the midpoint formula above and simplify.
M = ( (x₁+x₂)/2, (y₁+y₂)/2 )
M = ( ( 11 + 4 )/2, ( 3 + 3 )/2 )
M = ( ( 15 )/2, ( 6 )/2 )
Midpoint M = ( 15/2, 3 )

[tex]\begin{gathered} \begin{pmatrix}5&-2\\ \:\:\:4\:&-3\end{pmatrix}\times \begin{pmatrix}2&-1\\ \:\:3&1\end{pmatrix} \\ \begin{pmatrix}5\cdot \:2+\left(-2\right)\cdot \:3&5\left(-1\right)+\left(-2\right)\cdot \:1\\ 4\cdot \:2+\left(-3\right)\cdot \:3&4\left(-1\right)+\left(-3\right)\cdot \:1\end{pmatrix} \\ \begin{pmatrix}4&-7\\ -1&-7\end{pmatrix} \end{gathered}[/tex]) Thus, the se are theanswers .
If a nonlinear system of equations contains one linear function that touches the quadratic function at its minimum, then the system has which of the following?
A. No solution
B. Infinitely many solutions
C. One solution
D. Two solutions
Answer:
C. One solution
Step-by-step explanation:
You want to know the number of solutions of a system of equation such that the graph of the linear function touches the graph of the quadratic function at its minimum.
SolutionsThe number of real solutions of the system of equations is equal to the number of points of intersection of their graphs. The problem statement tells you the graphs intersect at one point, so there is one solution.
__
Additional comment
The linear function can only touch the minimum of a quadratic if its graph is a horizontal line.
