To find the missing angle measure, we need to use the fact that the sum of angles in a triangle is 180 degrees. Let's denote the missing angle as x. We know that one angle is 38 degrees and another angle is 12.5 degrees.Therefore, the missing angle measure is 129.5 degrees.
By subtracting these two angles from 180 degrees, we get:
180 - 38 - 12.5 = 129.5
Without additional information, it is not possible to determine the remaining parts of the triangle. We would need the lengths of at least one side or the measures of other angles to solve for the missing parts.
The given information states that AC is equal to AB minus mzB. Without knowing the values of AB and mzB, we cannot determine the exact length of AC. We would need additional information to solve for the length of AC.Therefore, the missing angle measure is 129.5 degrees.

Answer:
1 solution
2.88
Step-by-step explanation:
Consider this quadratic equation.
x ^2+ 2x + 7 = 21
Subtract 7 from both sides
x ^2+ 2x + 7 -7= 21-7
x^2+2x = 14

What are the coordinates of point (1, 5) after dilating by 1/3 about (4,2)?
(2, 1)
(-1,-5)
(3, 2)
(3, 3)
The coordinates of point (1,5) after dilation is (3,3). Therefore, 4th option is correct.
It is given to us that -
The coordinates of the original point is (1,5)
=> \((x_{o},y_{o} )=(1,5)\) ---- (1)
The dilating factor is 1/3
=> \(s=\frac{1}{3}\) (say) ---- (2)
And, the center of dilation is at the point (4,2)
=> \((x_{cod},y_{cod})=(4,2)\) ---- (3)
We have to find out the coordinates of point (1,5) after dilation.
Using the formula for dilation coordinates from original to image, we have
\([(x_{cod}+s(x_{o}-x_{cod}),y_{cod}+s(y_{o}-y_{cod})]\\=[4+\frac{1}{3}(1-4),2+\frac{1}{3}(5-2)]\\=[(4-1),(2+1)]\\=(3,3)\)

Simplify (2x-3)(5x squared-2x+7)
To simplify the expression (2x-3)(5x^2-2x+7), we can use the distributive property.
First, multiply 2x by each term inside the second parentheses:
2x * 5x^2 = 10x^3
2x * -2x = -4x^2
2x * 7 = 14x
Next, multiply -3 by each term inside the second parentheses:
-3 * 5x^2 = -15x^2
-3 * -2x = 6x
-3 * 7 = -21
Combine all the resulting terms:
10x^3 - 4x^2 + 14x - 15x^2 + 6x - 21
Now, combine like terms:
10x^3 - 19x^2 + 20x - 21

A town has a population of 1600 people at time t=0. In each of the following cases, write a formula for the population P, of the town as a function of year t.(a) The population increases by 70 people per year.(b) The population increases by 9 percent a year.
The population of the town at any given time t can be determined using the formulas provided. For example, if the town's population at time t=5 years is desired, the population can be calculated as follows:(a) P(5) = 1600 + 70(5) = 2100 people (b) P(5) = 1600(1.09)^5 = 2266.05 people
(a) P(t) = 1600 + 70t
(b) P(t) = 1600(1.09)^t
(a) In this case, the population increases by 70 people per year, so the formula for the population as a function of time is P(t) = 1600 + 70t. This means that the population is 1600 people at time t=0 and increases by 70 people for each additional year.
(b) In this case, the population increases by 9 percent each year, so the formula for the population as a function of time is P(t) = 1600(1.09)^t. This means that the population is 1600 people at time t=0 and increases by a factor of 1.09 (9 percent) for each additional year.
The population of the town at any given time t can be determined using the formulas provided. For example, if the town's population at time t=5 years is desired, the population can be calculated as follows:
(a) P(5) = 1600 + 70(5) = 2100 people
(b) P(5) = 1600(1.09)^5 = 2266.05 people

Find the trigonometric integral. (Use C for the constant of integration.)
Suppose we let \(u=\sin\theta+\cos\theta\), so that \(\mathrm du=(\cos\theta-\sin\theta)\,\mathrm d\theta\).
Also, recall the double angle identity for cosine:
\(\cos(2\theta)=\cos^2\theta-\sin^2\theta=(\cos\theta-\sin\theta)(\cos\theta+\sin\theta)\)
So, we can rewrite and compute the integral using the substitution, as
\(\displaystyle\int\cos(2\theta)(\sin\theta+\cos\theta)^3\,\mathrm d\theta\)
\(=\displaystyle\int u\cdot u^3\,\mathrm du\)
\(=\displaystyle\int u^4\,\mathrm du\)
\(=\dfrac{u^5}5+C\)
\(=\boxed{\dfrac{(\cos\theta+\sin\theta)^5}5+C}\)

Janet, an experienced shipping clerk, can fill a certain order in 2 hours. Tom, a new clerk, needs 3 hours to do the same job.
Working together, how long will it take them to fill the order?
Answer:
1 hour and 15 minutes.
Step-by-step explanation:
Since Janet, an experienced shipping clerk, can fill a certain order in 2 hours, while Tom, a new clerk, needs 3 hours to do the same job, to determine how long will it take them to fill the order by working together you must perform the following logical reasoning:
Each of them will do half the work, so in principle, Janet will do her work in 1 hour, while Tom will do it in 1 hour and a half. Now, the remaining half hour that Tom has more than Janet can in turn be divided in two, with which each one will do their work in 15 minutes. Thus, the order will be ready in 1 hour and 15 minutes.

Find the distance between the points P and Q shown.
The distance between points P and Q is √73
How to find the distance between the two points?First, remember that the distance between two points whose coordinates are (a, b) and (c, d) is given by:
distance = √( (a - c)² + (b - d)²)
Here we can see that the coordinates of the two shown points are:
P = (-3, 2)
Q = (5, -1)
Replacing that in the distance formula we will get:
distance = √( (-3 - 5)² + (2 + 1)²)
distance = √( (-8)² + (3)²)
distance = √73

The decimal number will be rounded to the nearest hundredth value as 1.93 to the nearest hundredth.
What about the nearest hundredth?Look at the rightmost place value to see how to round a number to the closest hundredth (the thousandths this time). In the same way, simply eliminate all the digits to the right if the number is four or less. Remove all the digits to the right after adding 1 to the digit in the hundredths position if the number is five or above.
Take into account the hundredths place (9) to convert 1.299 to the nearest tenth, 1.3. To round to the nearest hundredth, consider the thousandths place (9) The tenth would be rounded up in this situation to the nearest whole number, 1.30, which is equal to 1.3.

DFS can be used because the graph is directed and all of the edge weights are positive.
What is Algorithms?
An algorithm is a process used to carry out a computation or solve a problem. In either hardware-based or software-based routines, algorithms function as a detailed sequence of instructions that carry out predetermined operations sequentially. All aspects of IT employ algorithms extensively.
Steps can be taken. There may be a path from v to z* but not from z* to v or different from each with different weights, so we just need to apply DFS, dijkstras twice, starting with vertex v, to find the path length until z*. Then we need to add the path weights.
The problem is clear in that we need to find path weight from v to z* and z* to v. There may be more than one path that leads from v to z*, thus we must locate them all and store some of them because each loop will require a time complexity of O(V+E).
where, in the given graph, E stands for edges and V for vertex. When a graph is complete, meaning there is a path connecting every vertex to every other vertex, we must execute this technique V times to determine the total number of paths. As a result, the time complexity is O(V(V+E)).
Then we must repeat the process from z* to v, but this time we must choose every path whose weights satisfy the specified condition. In the worst case, we must repeat this process (V-1) times, thus the time complexity will be the same as before. As a result, our time complexity will be O(V(V+E)) overall.
Since the graph is directed and every edge weight is positive, DFS may be used.
