Answer:
Whole numbers
Explanation:
The domain of a function is the set of all the possible values that the variable x can take. In this case, x represents the number of Chromebooks, so x can take values like 0, 1, 2, 3, ...
Therefore, the c(x) domain is the set of whole numbers because these are the numbers that we use to count.
Use the Law of Sines to solve the triangle. Round your answers to two decimal places.A = 8° 40', B = 13° 15', b = 4.8
Given
[tex]A=8°40^{\prime},B=13°15^{\prime},b=4.8[/tex]To find the value of a, c, C.
Explanation:
It is given that,
[tex]A=8°40^{\prime},B=13°15^{\prime},b=4.8[/tex]Since,
[tex]A=8°40^{\prime},B=13°15^{\prime}[/tex]Then,
[tex]\begin{gathered} A+B+C=180 \\ 8\degree40^{\prime}+13\degree15^{\prime}+C=180\degree \\ C=180\degree-21\degree55^{\prime} \\ C=(179-21)\degree(60^-55^)^{\prime} \\ C=158\degree5^{\prime} \end{gathered}[/tex]Therefore, by using Sine law,
[tex]\begin{gathered} \frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c} \\ \frac{\sin8\degree40^{\prime}}{a}=\frac{\sin13\degree15^{\prime}}{4.8}=\frac{\sin158\degree5^{\prime}}{c} \\ \Rightarrow\frac{\sin8\degree40^{\prime}}{a}=\frac{\sin13\degree15^{\prime}}{4.8} \\ \Rightarrow\frac{\sin13\degree15^{\prime}}{4.8}=\frac{\sin158\degree5^{\prime}}{c} \end{gathered}[/tex]Therefore,
[tex]\begin{gathered} \begin{equation*} \frac{\sin8\degree40^{\prime}}{a}=\frac{\sin13\degree15^{\prime}}{4.8} \end{equation*} \\ \frac{0.14608}{a}=\frac{0.227501}{4.8} \\ a=\frac{0.14608}{0.047396} \\ a=3.08211 \\ a=3.1 \end{gathered}[/tex]Also,
[tex]\begin{gathered} \begin{equation*} \frac{\sin13\degree15^{\prime}}{4.8}=\frac{\sin158\degree5^{\prime}}{c} \end{equation*} \\ 0.047396=\frac{0.366501}{c} \\ c=\frac{0.366501}{0.047396} \\ c=7.73274 \\ c=7.7 \end{gathered}[/tex]Hence, the answer is
[tex]C=158\degree5^{\prime},a=3.1,c=7.7[/tex]What is the value of n?
Answer:
[tex]n = { \boxed{ - \frac{2}{3} }}[/tex]
Step-by-step explanation:
[tex] \frac{1}{( {\sqrt[3]{5}})^{2} } = {5}^{n} \\ [/tex]
- Change or convert the cube root into an index form; ³√x = x^⅓
[tex] \frac{1}{( {5}^{ \frac{1}{3} }) {}^{2} } = {5}^{n} \\ [/tex]
- Open the brackets by multiplying the powers; (a²)² = a²×²
[tex] \frac{1}{ {5}^{( \frac{1}{3} \times 2)} } = {5}^{n} \\ \\ \frac{1}{ {5}^{ \frac{2}{3} } } = {5}^{n} [/tex]
- Following the law of indices below;
[tex]{ \boxed{ \blue{ \pmb{( \frac{1}{ {x}^{a} } ) = {x}^{ - a} }}}}[/tex]
- Therefore;
[tex] {5}^{ - \frac{2}{3} } = {5}^{n} \\ [/tex]
- Since the bases (5) are the same, the powers are equal;
[tex]n = - \frac{2}{3} [/tex]

Write your answer in the form y=mx+b
An equation of line with slope m = 5 and which goes through the point (8, -9) is y = 5x - 49
In this question, we have been given a slope of the line and a point (8, -9)
We need to find an equation of the line with slope m = 5 and which goes through the point (8, -9)
Let (x1, y1) = (8, -9)
Using the slope-point form of the line,
y - y1 = m(x - x1)
y - (-9) = 5(x - 8)
y + 9= 5x - 40
y = 5x - 40 - 9
y = 5x - 49

1) how many mg are equal are in 64 hectometers?2) 52000 micrometers (um) to Gm (giga)
1) 64 * 10^5 mg 2) 5.2 * 10^-11gm
Explanation:
There is no direct conversion from mg to hectometers
The conversions available:
1 m³ = 10^-6 hm³
where hm = hectometer
Also 1 hm³ = 1 * 10 ^15 mg
64 hm³ = 64 * 1 * 10 ^15 mg
= 64 * 10 ^15 mg
1 hm³ = 1hm * 1hm * 1hm
To get 1 hm, we will find the cube root of the value in mg:
[tex]\begin{gathered} 1hm\text{ = }\sqrt[3]{10^{15}mg} \\ 1\text{ hm = }10^5mg \\ 64\text{ hm = 64}\times10^{^5}mg \end{gathered}[/tex]64 hectometers = 64 * 10^5 mg
2) 1 µm = 10^-15gm
52000 µm = 52000 * 10^-15gm
= 5.2 * 10 ^4 * 10^-15gm = 5.2 * 10^(4-15) gm
= 5.2 * 10^-11gm

Here is the answer: {2,3,4}
option A
Options for the first time:increases, remains the same, decreases Options for the second box: increases, remains the same, decreases Options for the third box: reflects over the x-axis, remains the same, reflects over the y-axis
The general form of a trigonometric function is:
[tex]A\sin (B(x-C))+D[/tex]Where B is the frequency of the function.
In our problem, A=1, C=D=0.
Then, as the value of B increases, so the frequency does. The answer to the second gap is 'increases'.
On the other hand, let P be the period and f the frequency. Those two quantities are related by the formula:
[tex]f=\frac{1}{P}[/tex]Then, if the frequency increases, the period decreases. The answer to the first gap is 'decreases'.
Finally, if B is negative we have that:
[tex]\begin{gathered} B<0,A=-B,A>0 \\ \Rightarrow\tan (Bx)=\frac{\sin(Bx)}{\cos(Bx)}=\frac{\sin(-Ax)}{\cos(-Ax)}=-\frac{\sin(Ax)}{\cos(Ax)}=-\tan (-Bx) \end{gathered}[/tex]Therefore, the function is reflected over the x-axis.

A computer program found that the line c = 2t - 89 is a good fit for the data, Use this equation to predict how many cups of lemonade Lin might sell on a day when the high temperature is 74 degrees. Enter your answer in the box below. Answer:Ocups. The high temperature this Sunday is expected to be 5 degrees warmer than the high temperature this Saturday. Using the line c = 2t - 89. how many more cups of lemonade should Lin expect to sell on Sunday than Saturday? Explain or show your reasoning. Enter your response here
Part 1. Find how many cups will Lin sell when the high temperature is 74°.
We are given the expression:
[tex]c=2t-89[/tex]Where is c is the number of cups that Lin might sell and t is the high temperature.
We have the value of the high temperature:
[tex]t=74[/tex]And to solve this problem we need to substitute t=74 into the given expression:
[tex]\begin{gathered} c=2t-89 \\ \text{Substituting t=74} \\ c=2(74)-89 \end{gathered}[/tex]Solving the operations:
[tex]\begin{gathered} c=148-89 \\ c=59 \end{gathered}[/tex]Answer (for part 1): 59 cups.
Part 2. Find how many more cups of lemonade Lin should sell on Sunday than Saturday.
We will call the high temperature on Saturday "x". The number of cups that Lin Might sell for x temperature is:
[tex]c=2x-89[/tex]Now, we are told that the temperature on Sunday is expected to be 5° warmer, so we represent the high temperature on Sunday as 5 more than the temperature on Saturday (which we called x).
Thus, the temperature on Sunday is:
[tex]t=x+5[/tex]And we substitute this into the expression:
[tex]\begin{gathered} c=2t-89 \\ \text{Substituting t=x+5} \\ c=2(x+5)-89 \end{gathered}[/tex]Using the distributive property on the right-hand side of the equation:
[tex]\begin{gathered} c=2x+2\cdot5-89 \\ c=2x+10-89 \end{gathered}[/tex]Re-arranging the expression:
[tex]c=(2x-89)+10[/tex]Comparing this with the expression we got for Saturday:
[tex]\begin{gathered} \text{Saturday:} \\ c=2x-89 \\ \text{Sunday:} \\ c=(2x-89)+10 \end{gathered}[/tex]As you can see, 10 more cups were sold on Sunday than on Saturday.

We have two events:
A: sum of the numbers is less than 10.
B: sum of the numbers is a multiple of 3.
We can calculate the probabilities as a quotient of the "success" events and all the possible events.
The conditional probability P(B | A) is equal to the probability of P(A intersection B) divided by P(A). That is because, if A is given, then if B happens, A had also happen.
The "success" events for intersection A and B are:
{1,2}, {2,1}, {1,5}, {5,1}, {2,4}, {4,2}, {3,3}, {3,6}, {6,3}, {4,5}, {5,4}
There are a total of 11 results that belong to the intersection of A and B (sum less than 10 and multiples of 3).
Now, we calculate the results that correspond to event A:

The countries with the most widgets in the world are the United States and France. If the United States has 2006 more widgets than France and the total number of widgets is 8306. Find the number of widgets for each country.
Given:
a.) The United States has 2006 more widgets than France.
b.) The total number of widgets is 8306.
Let,
x = The number of widgets the United States has
y = The number of widgets France have
x = y + 2006 ; Since the United States has 2006 more widgets than France.
From the given scenario, we generate the following equation:
[tex]\text{ x + y = 8306}[/tex]Let's determine the value of x and y.
[tex]\text{ x + y = 8306}[/tex][tex]\text{ (}y+2006)\text{ + y =8306}[/tex][tex]\text{ }y+2006\text{ + y =8306}[/tex][tex]\text{ }y+\text{ y =8306 - }2006[/tex][tex]\text{ 2y = }6,300[/tex][tex]\text{ }\frac{\text{2y}}{2}\text{ = }\frac{6,300}{2}[/tex][tex]\text{ y = }3150[/tex]Therefore, France has 3150 Widgets.
Let's determine the number of fidgets the United States has. Use y = 3150 in the equation x + y = 8306.
[tex]x+y=8306[/tex][tex]x+3150=8306[/tex][tex]x=8306\text{ - }3150[/tex][tex]x=5156[/tex]Therefore, the United States has 5156 Widgets.
