Law of cosines: a2 = b2 + c2 – 2bccos(A) Find the measure of J, the smallest angle in a triangle with sides measuring 11, 13, and 19. Round to the nearest whole degree. 30° 34° 42° 47°
The smallest angle occurs opposite the shortest side length of the triangle. So by the law of cosines we have
[tex]11^2=13^3+19^2-2\cdot13\cdot19\cos\angle J\implies\cos\angle J=\dfrac{409}{494}\implies\theta\approx\boxed{34^\circ}[/tex]
Answer:
The measure of angle J is 34°
Step-by-step explanation:
Given,
J is the smallest angle in the triangle with sides measuring 11, 13, and 19,
Thus, J must be the opposite angle of the side measuring 11,
Since, the law of cosines,
[tex]a^2 = b^2 + c^2 - 2bc cos A[/tex]
Where, a, b and c are the sides of a triangle ABC,
Such that angle A is opposite to the side measuring a,
By applying the law,
We can write,
[tex]11^2 = 13^2 + 19^2 - 2\times 13\times 19 cos J[/tex]
[tex]121 = 169 + 361 - 494 cos J[/tex]
[tex]\implies cos J = \frac{169+361-121}{494}=\frac{409}{494}[/tex]
[tex]\implies m\angle J=34.1127839945\approx 34^{\circ}[/tex]

Answer:
a + b - c - d
Step-by-step explanation:
The rules of exponents are ...
(x^a)(x^b) = x^(a+b)
(x^a)/(x^b) = x^(a-b)
Using these rules on your expression, we can simplify it to ...
(3^a) · (3^b) ÷ (3^c) ÷ (3^d)
= 3^(a+b) ÷ (3^c) ÷ (3^d)
= 3^(a+b-c) ÷ (3^d)
= 3^(a+b-c-d)

At 73°F a certain insect chirps at a rate of 97 times per minute, and at 80°F, they chirp 132 times per
minute. Write an equation in slope-intercept form that represents the situation.
Answer:
The equation is: y = 5x - 268
Explanation:
We are given that:
At 73°F, the chirp is 97 times per minute .........> first point is (73, 97)
At 80°F, the chirp is 132 times per minute .......> second point is (80, 132)
The general equation of the linear line is:
y = mx + c
where m is the slope and c is the y-intercept
1- getting the slope:
The slope can be calculated using the following rule:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute with the given points to get the slope as follows:
[tex]m = \frac{132 - 97}{80 - 73} = 5[/tex]
The equation, now, became:
y = 5x + c
2- getting the y-intercept:
To get the y-intercept, use any of the given points and substitute in the rule we got in part 1. I will use the point (80, 132)
Therefore:
y = 5x + c
132 = 5(80) + c
c = 132 - 5(80) = -268
The equation, therefore, is:
y = 5x - 268

Which location has the least variability in temperatures? Explain how you arrived at your answer.
Answer:
Los Angeles
Step-by-step explanation:
Los Angeles has the least variability in temperatures.
To determine which location has the least variability in temperatures, we need to calculate the range or variance of the temperatures for both Miami and Los Angeles.
For Miami:
Temperatures: 76 75 83 73606676 81 83 85 83 87 8080 74
To calculate the range, we subtract the minimum temperature from the maximum temperature:
Range = Maximum temperature - Minimum temperature
Range = 87 - 73
Range = 14
For Los Angeles:
Temperatures: 63 62 65 72 67 | 65 | 6565 69 64 64 61 3639 62
Again, to calculate the range, we subtract the minimum temperature from the maximum temperature:
Range = Maximum temperature - Minimum temperature
Range = 72 - 61
Range = 11
Comparing the ranges, we see that Miami has a range of 14, while Los Angeles has a range of 11. Therefore, Los Angeles has the least variability in temperatures.

What is the probability of an event that is impossible? Suppose that a probability is approximated to be zero based on empirical results. Does this mean that the event is impossible?
Answer:
The probability of an event that is impossible is zero (0)No, a probability approximated to be zero based on empirical results does not mean that the event is impossible.Explanation:
For the first question, the mathematical (statistical, to be more precise) definition of a event that is impossible is that its probability is zero.
There are two extremes when you talk about probability: 0 and 1. 0 means that the event cannot occur in any way, while 1 is that the event is certain (it cannot not happen).
An example of an event with probability 0 is: men born in the Sun. This is an impossible event, and so there is no chance (probability 0) to find a man born in the Sun.
For the second question, when you deal with empirical results, this is with an experiment, the fact of having a probability zero as result of approximations does not make that an event be impossible; the event is unlikely (if the experiments were carried out properly) but yet it can happen.
For example, say you put 1,000 ballots in a bag with the number 3, together with 1 ballot with the number 9. Then, you perform the experiment of drawing a ballot 2,000 times. Suppose you draw the ballot with the number 9 two times. In that case, your approximated experimental probability of drawing a 9 will be 2 /2,000 = 0.001. Which you could round to 0.00. That may be valid but it cannot be taken as that the event of drawing the ballot with the number 9 is impossible, it is just unlikely.

A. 243/2048
B. -243/2048
C. 81/1024
D. -81/1024
Answer:
The sixth term is -243/2048 ⇒ answer B
Step-by-step explanation:
* Lets explain the geometric sequence
- There is a constant ratio between each two consecutive numbers
- Ex:
# 5 , 10 , 20 , 40 , 80 , ………………………. (×2)
# 5000 , 1000 , 200 , 40 , …………………………(÷5)
* General term (nth term) of a Geometric sequence:
# U1 = a , U2 = ar , U3 = ar² , U4 = ar³ , U5 = ar^4
# Un = ar^(n-1), where a is the first term , r is the constant ratio
between each two consecutive terms and n is the position of the
number in the sequence
- Ex: U5 = ar^4 , U7 = ar^6 , U10 = ar^9 , U12 = ar^11
- Lets solve the problem
∵ The sequence is 1/2 , -3/8 , 9/32
- Lets find the constant ratio r
∵ The first term is a = 1/2
∵ The second term is U2 = ar
∵ The second term U2 = -3/8
∴ ar = -3/8
∴ 1/2 r = -3/8 ⇒ multiply both sides by 2
∴ r = -3/4
- Lets find the sixth term
∵ a = 1/2 and r = -3/4
∵ n = 6
∴ U6 = ar^5
∴ U6 = 1/2 (-3/4)^5 = 1/2 × -243/1024 = -243/2048
* The sixth term is -243/2048

Given graph for function f(x) given above, find the f(-2). f(-2) =
Answer:
f(-2) = 3
Step-by-step explanation:
The graph goes through the point (-2, 3), indicating the value of f(x) is 3 when x=-2.
Which transformation from the graph of a function f(x) describes the graph of f(x)-1?
Answer:
Step-by-step explanation:
Any side to side movement of a function will be reflected inside a set of parenthesis with the x. For example, if the function was a parabola, the parent graph could be, very simply,
[tex]y=x^2[/tex]
Side to side movement would make the equation look like this:
[tex]y=(x-h)^2[/tex]
where h is the x coordinate of the vertex.
Up or down movment would make the equation look like this:
[tex]y=x^2+k[/tex] for movement upwards, or
[tex]y=x^2-k[/tex] for movement downwards. The k represents the y coordiante of the vertex in this parabola.
Because our function has NO numbers inside the parenthesis with the f(x), but it has a -1 after, we are moving the parent graph of this function, whatever it is, down one from its starting position.
The transformation from the graph of a function f(x) describes the graph of f(x) - 1 is a vertical shift down by 1 unit
From the question, we have the following parameters that can be used in our computation:
The function f(x)
Also, we have
The function f(x) - 1
Subtracting a value from a function means that the function is shifted down
In this case, the subtracted value is 1
This means that f(x) - 1 is a vertical shift down by 1 unit from f(x)
Find the area of this rhombus
The answer is:
The area of the rhombus is equal to 64 squared inches.
[tex]area=64in^{2}[/tex]
Why?Since we already know half of the length of the diagonals of the rhombus, we can calculate the area of the rhombus using the following formula:
[tex]area=\frac{diagonal_{1}*diagonal_{2}}{2}[/tex]
From the image we can see that:
[tex]diagonal_{1}=8in+8in=16in[/tex]
[tex]diagonal_{2}=4in+4in=8in[/tex]
So, substituting, we have:
[tex]area=\frac{16in*8in}{2}=\frac{128in^{2} }{2}=64in^{2}[/tex]
Hence, we have that the area of the rhombus is equal to 64 square inches.
Have a nice day!
Answer: SECOND OPTION.
Step-by-step explanation:
You can calculate the area of the rhombus with this formula:
[tex]A=\frac{d_1*d_2}{2}[/tex]
Where [tex]d_1[/tex] and [tex]d_2[/tex] are the lengths of the diagonals.
You can observe in the figure that the length of each diagonal is:
[tex]d_1=4in+4in=8in\\d_2=8in+8in=16in[/tex]
Now you can substitute the lenghts of the diagonals into the formula. Therefore, the area of this rhombus is:
[tex]A=\frac{(8in)(16in)}{2}[/tex]
[tex]A=\frac{128}{2}[/tex]
[tex]A=64in^2[/tex]

Big Bob's Pizza is having a special on pizza and is offering two different choices: Choice #1: One slice of pizza from a pizza with a 22 inch diameter and is cut into 8 slices. The cost is $4.95. Choice #2: An entire personal-size pizza that has a diameter of 6 inches. The cost is $3.75. Which choice will give you more pizza for your money? Justify your answer using numbers and words.
The special at Big Bob's Pizza which will give you more pizza for your money is Choice #1. Per square inch, Choice #1 will cost less and give more overall pizza at $0.10 a square inch then Choice #2 at $0.13 per square inch. You can find more pizza for your money, by using the area formula for a circle for each pizza and finding the price per square inch of each serving. This is called a unit rate and is the cost per unit.
Further Explanationa. Find the radius of each pizza.
Since a pizza is a circle shape, it has a diameter and radius. The diameter is the distance across the pizza and the radius is half the diameter. We use the radius to find the area.
Choice #1: One slice of a pizza with a 22 inch diameter and is cut into 8 slices. Since the diameter is the distance across the pizza, 22 inch diameter means the pizza is 22 inches wide. The area formula uses the radius or half the diameter. The radius of choice #1 is 11 inches.Choice #2: An entire personal-size pizza that has a diameter of 6 inches. Here the radius is half of 6 inches. The radius of choice #2 is 3 inches.b. Find the area of each pizza using [tex]A = \pi r^{2}[/tex].
Choice #1: Substitute r = 11 into the formula then divide by 8 to find the area of one slice or serving.[tex]A = \pi r^{2} \\A = \pi (11)^{2} \\A = 121\pi \\A= 379.94[/tex]
The area of one slice is [tex]\frac{379.94}{8} = 47.49.[/tex]
Choice #2: Substitute r = 3 into the formula. This is a personal pizza so the entire pizza is a serving.[tex]A = \pi r^{2} \\A = \pi (3)^{2} \\A = 9\pi \\A= 28.26[/tex]
c. Divide each area by the price.
The cost of Choice #1 is $4.95. Since the serving size is 1 slice, use the area of the slice 47.49. Divide it into the price to find the cost per square inch of one serving.[tex]\frac{4.95}{47.49} = 0.10[/tex]
The cost of Choice#2 is $ 3.75. Since the serving serving size is the entire personal pizza, use the area of the pizza 28.26.[tex]\frac{3.75}{28.26} = 0.13[/tex]

Does the graph of any relation have end behaviors that can be described the same way as the end behaviors of a polynomial relation?
Answer:
No
Step-by-step explanation:
Not all relations have either an infinite domain or an infinite range. Some have no "end behavior". A sine function, for example, continues to oscillate between -1 and +1 forever.
The graphs of some relations are simply a collection of points, so the "end behavior" would be the points at either extreme of the domain.
