To solve the equation, we should isolate x on one side and the numerical term on the other side
So we have to multiply both sides by 2 to cancel the denominator 2 from the right side
[tex]\begin{gathered} 6\times2=\frac{(x+3)}{2}\times2 \\ 12=x+3 \end{gathered}[/tex]Now want to move 3 from the right side to the left side
Subtract 3 from both sides
[tex]\begin{gathered} 12-3=x+3-3 \\ 9=x \end{gathered}[/tex]The solution is x = 9

A)
[tex]\begin{gathered} c=17.159 \\ A=4.747\text{\operatorname{\degree}} \\ B=85.253\operatorname{\degree} \end{gathered}[/tex]Explanation
Explanation
Step 1
c) to find the measure of the hypotenuse we can use the Pythagorean theorem, it states that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)
[tex]a^2+b^2=c^2[/tex]Step 1
a) Let

Given:
Center of the circle = P
Let's determine the following:
a) Radius.
Here, the radius of the circle is the hypotenuse of the triangle.
Therefore, the radius of the circle is 3 units
b) Center:
To find the point at the center of the circle, let's locate the point P on the graph.

5g + h =g solve for g
You have the following equation:
5g + h = g
In order to solve for g, you first organize the previous equation, as follow:
5g + h = g substract g both sides and substract h both sides too
5g - g = -h
4g = -h dive by 4 both sides
g = -h/g
Then, the answer is g = -h/g
Cook-It rice cooker has a mean time before failure of 42 months with a standard deviation of 3 months, and the failure times are normally distributed. What should be the warranty period, in months, so that the manufacturer will not have more than 9% of the rice cookers returned? Round your answer down to the nearest whole number.
From the statement, we have a normal distribution with:
• variable X = time before failure,
,• mean μ = 42 months,
,• standard deviation σ = 3 months.
We want to know for how much time the manufacturer will not have more than 9% of the rice cookers returned. So this is equivalent to finding the value x such that the probability of failure is lower than 9%:
[tex]P(X\leq x)=9\%=0.09.[/tex]We can compute this probability using the z-scores:
[tex]\begin{gathered} P(Z\leq z)=0.09, \\ z=\frac{x-\mu}{\sigma}\Rightarrow x=\mu+\sigma\cdot z=42+3\cdot z. \end{gathered}[/tex]We have the following table for z-scores:
The entries in the table represent the area under the curve, i.e. the probability. We must look for the closest value to the probability of 0.09. From the table, we see that the closest value to this probability is 0.091:
For this value we see that we have the z-score:
[tex]z=-1.34.[/tex]Replacing this value in the equation for x from above, we get:
[tex]x=42+3\cdot(-1.34)=37.98.[/tex]So we have found that for x = 37.98, we have:
[tex]P(X\leq x=37.98)=9\%=0.09.[/tex]This means that by a time x = 37.98 months, only 9% of the cookers will fail have failed. So the manufacturer must set a warranty period of 38 months to not have more than 9% of the rice cookers returned.
AnswerThe manufacturer must set a warranty period of 38 months to not have more than 9% of the rice cookers returned.

In order to add the mixed numbers given, we first convert the mixed numbers to improper fractions.
Now,
[tex]3\frac{7}{3}=3+\frac{7}{3}[/tex]The number 3 can be rewritten as
[tex]7=3\cdot\frac{3}{3}[/tex]which helps us rewrite our mixed fraction as
[tex]3+\frac{7}{3}=3\cdot\frac{3}{3}+\frac{7}{3}[/tex][tex]=\frac{9}{3}+\frac{7}{3}[/tex]adding the numerators gives
[tex]\frac{16}{3}[/tex]Hence,
[tex]3\frac{7}{3}=\frac{16}{3}[/tex]Similarly,
[tex]2\frac{5}{6}=2+\frac{5}{6}[/tex]the number 2 can be rewritten as
[tex]2=2\cdot\frac{6}{6}=\frac{12}{6}[/tex]therefore, the mixed number becomes
[tex]2+\frac{5}{6}=\frac{12}{6}+\frac{5}{6}[/tex][tex]=\frac{17}{6}[/tex]Hence,
[tex]2\frac{5}{6}=\frac{17}{6}[/tex]Now with mixed numbers rewritten as improper fractions, we are ready to add
[tex]3\frac{7}{3}+2\frac{5}{6}=\frac{16}{3}+\frac{17}{6}[/tex]rewriting 16/3 as 16/3 * 2/2 gives
[tex]\frac{16}{3}=\frac{32}{6}[/tex]therefore, we have
[tex]\frac{16}{3}+\frac{17}{6}=\frac{32}{6}+\frac{17}{6}[/tex]and now we just add the denominators to get
[tex]\frac{32}{6}+\frac{17}{6}=\frac{49}{6}[/tex]Hence,
[tex]3\frac{7}{3}+2\frac{5}{6}=\frac{49}{6}[/tex]which is our answer!

The vertex form equation is y = (x-3)^2 - 14
The equation y = x^2-6x+5 is really the equation y = 1x^2-6x+5. It is in the form y = ax^2 + bx + c where
a = 1
b = -6
c = 5
We will use 'a' and 'b' in the formula below
h = -b/(2a)
h = -(-6)/(2*(1))
h = 6/(2)
h = 3
The h refers to the x coordinate of the vertex. Since we know the x coordinate of the vertex (is 3), we can use it to find the y coordinate of the vertex
Simply plug x = 3 into the original equation
y = x^2 - 6x + 5
y = -(3)^2 - 6(3) + 5
y = (9) - 6(3) + 5
y = +9-18+5
y = -4
This is the k value, so k = -4.
In summary so far, we have a = -1, h = 3 and k = -4. Plug all this into the vertex form below
y = a(x-h)^2 + k
y = 1(x-3)^2 -4
y = (x-3)^2 - 14
Therefore the vertex form equation is y = (x-3)^2 - 14

probability experiment4.4 Given that a spinner lands on a prime number, find the probability that the arrow will land on an odd number.
To determine the probability of an event to occur, the formula is:
[tex]P(x)=\frac{noof\text{ favorable outcomes}}{no.\text{ of total possible outcomes}}[/tex]In the spinner, there are 6 possible outcomes. The arrow can either point from 1 to 6.
4.1. In the spinner, there are 3 prime numbers. These are 2, 3, and 5. Hence, there are 3 favorable outcomes if we want to have a prime number as a result after the spin. The probability of that happening will be:
[tex]P(x)=\frac{3}{6}=\frac{1}{2}=0.5[/tex]The probability of spinning a prime number is 1/2 or 0.5 or 50%.
4.2. We have already mentioned that there are 3 prime numbers (2, 3, 5). For odd numbers, we also have 3 and these are 1, 3, and 5. Combining the two, we get {1, 2, 3, 5} as either prime or odd numbers. As we can see, there are 4 favorable outcomes. Therefore, the probability is:
[tex]P(x)=\frac{4}{6}=\frac{2}{3}[/tex]The probability of spinning a prime number or an odd number is 2/3.
4.3. We have already mentioned that there are 3 prime numbers (2, 3, 5). For multiple of 3, we only have {3, 6}. Since the given operation is AND, that means, we have to find the intersection or what's common of both data. As we can see, only {3} is common. This means, only 3 is both a prime number and a multiple of 3. There is only 1 favorable outcome. The probability is:
[tex]P(x)=\frac{1}{6}[/tex]The probability of spinning a prime number and a multiple of 3 is 1/6.
4.4. If it has been already given that the number lands on a prime number, this means that we only have 3 choices or 3 possible outcomes. It's either 2, 3, or 5. Out of the 3 prime numbers, there are only 2 odd numbers and these are 3 and 5. Hence, the probability is:
[tex]P(x)=2\text{ out of 3}=\frac{2}{3}[/tex]Given that a spinner lands on a prime number, the probability of spinning an odd number is 2/3.

Hi, can you help me with this problem?A manufacturer has a monthly fixed cost of $42,500 and a production cost of $6 for each unit produced. The product sells for $11/unit.(a) What is the cost function?C(x)= (b) What is the revenue function?R(x)=(c) What is the profit function?P(x)= (d) Compute the profit (loss) corresponding to production levels of 6,000 and 11,000 units.P(6,000)=P(11,000)=
Given:
Fixed cost = b = $ 42,500
Production cost (Variable cost) /unit = m = $ 6/ unit
Let 'x' represent the number of unit, therefore the variable cost will be
[tex]6x[/tex]a) The cost function will be the sum of the fixed cost and the variable cost.
[tex]C(x)=6x+42500[/tex]b) The revenue function is the amount the product is sold per unit.
Recall: 'x' represents the number of units.
Therefore,
[tex]11\times x=11x[/tex]Hence, the revenue function R(x) is
[tex]R(x)=11x[/tex]c) The profit function is the difference between the revenue function and the cost function.
[tex]P\mleft(x\mright)=11x-\mleft(425000+6x\mright)=5x-42500[/tex]Hence, the profit function is
[tex]P\mleft(x\mright)=5x-42500[/tex]d) Let us compute the profit (loss) values when the units are 6000 and 11000
Using the profit function
[tex]P(x)=5x-42500[/tex]Therefore,

In the first paragraph,
It is given that a group of 26 people started a settlement and the population increased by an average of 2.6 people a year.
We can represent the population function as ;
g(x) = 26 + 2.6 x
Where x denotes the number of years and g(x) is the population after some certain years.
At a nearby community, it was discovered that the population can be written as;
f(x) = -5.3x + 256
Part A.
The population can be expressed as a function because the population at a particular time depends on the number of years x.
Specifically, it can be represented as a linear function because the rate at which the population increases per year is constant.
Part B.
Equating the functions
-5.3x + 256 = 26 + 2.6x
=> 5.3x + 2.6x = 256 - 26
=> 7.9x = 230
=> x = 29
Therefore, if the number of years is less than 29
The population of the first community will be less than the population of the second community
If the number of years is greater than 29
The population of the first community will be greater than the population of the second community

Given the fraction 3 7/9 + 4 10/12
Add the numbers first
3 + 4 = 7
Then the fractions
7/9 + 10/12
The lowest common multiple of 12 and 9 ( the denominators) is 36
Divide the denominators by 36 and multiply the result with the numerators
(7*4 + 10 * 3)/36
= (28 + 30)/36
= 58/36
= 29/18
= 1 11/18
Add this to the sum of the wholes munbers done earlier
= 7 + 1 11/18
=8 11/18
