Type in the correct value for m... (Only the numerical answer)
369 + m = 908
m(x)=x(x+6)
p(x)=x(x+3)²-9
Show that m(x) and p(x) are equivalent
Answer:
m=x+6
Step-by-step explanation:
Let's solve for m.
mx=x(x+6)
Step 1: Divide both sides by x.
2x/x= x²+6x/x
m=x+6

x to the second power is 49 what is x?
Answer:
7 or -7
Step-by-step explanation:
the question is asking for x to to the second power which is x squared or x^2
so setting x^2=49
square root both sides of the equation so that x is by itself and the other side is just ±√(49). which ±√49 is just 7 or -7

X has a volume of 130 cm^3 and a surface area of 202^2 cm?.
The volume of Y is 638.69 cm^3.
What is the surface area of Y?
Answer:
992.43 cm²
Step-by-step explanation:
From the question given above, the following data were obtained:
Volume of shape X (Vₓ) = 130 cm³
Surface area of shape X (SAₓ) = 202 cm²
Volume of shape Y (Vᵧ) = 638.69 cm³
Surface area of shape Y (SAᵧ) =?
The surface area of shape Y can be obtained as follow:
Since the shape are similar, then:
Vₓ / Vᵧ = SAₓ / SAᵧ
130 / 638.69 = 202 / SAᵧ
Cross multiply
130 × SAᵧ = 638.69 × 202
130 × SAᵧ = 129015.38
Divide both side by 130
SAᵧ = 129015.38 / 130
SAᵧ = 992.43 cm²
Thus, surface area of shape Y is 992.43 cm²

Find the equation of the graph given below. Notice that the sine function is used in the answer template, representing a sine function that is shifted and/or reflected.
Use the variable x in your equation rather than the multiplication × symbol.
y = __ sin (___) + (___)
Given:
The graph of a sine function.
To find:
The sine function.
Solution:
The general form of a sine function is
[tex]y=Asin(Bx+C)+D[/tex] ...(i)
Where, |A| is amplitude, [tex]\dfrac{2\pi}{B}[/tex] is period, [tex]-\dfrac{C}{B}[/tex] is phase shift and D is mid-line.
From the given graph it is clear that the minimum value of the function is -4 and the maximum value is 0.
[tex]|A|=\dfrac{Maximum-Minimum}{2}[/tex]
[tex]|A|=\dfrac{0-(-4)}{2}[/tex]
[tex]|A|=\dfrac{4}{2}[/tex]
[tex]|A|=2[/tex]
The graph is reflected across the mid-line, so A=-2.
And,
[tex]D=\dfrac{Maximum+Minimum}{2}[/tex]
[tex]D=\dfrac{0+(-4)}{2}[/tex]
[tex]D=\dfrac{-4}{2}[/tex]
[tex]D=-2[/tex]
Period of the function is 4π because it completer its one cycle in the interval of 4π.
[tex]4\pi=\dfrac{2\pi}{B}[/tex]
[tex]B=\dfrac{2\pi}{4\pi}[/tex]
[tex]B=\dfrac{1}{2}[/tex]
Phase shift is [tex]\dfrac{\pi}{4}[/tex].
[tex]-\dfrac{C}{B}=\dfrac{\pi}{4}[/tex]
[tex]-\dfrac{C}{\frac{1}{2}}=\dfrac{\pi}{4}[/tex]
[tex]C=-\dfrac{1}{2}\times \dfrac{\pi}{4}[/tex]
[tex]C=-\dfrac{\pi}{8}[/tex]
Putting [tex]A=-2,B=\dfrac{1}{2},C=-\dfrac{\pi}{8},D=-2[/tex] in (i), we get
[tex]y=-2\sin\left(\dfrac{1}{2}x-\dfrac{\pi}{8}\right)-2[/tex]
Therefore, the required equation is [tex]y=-2\sin\left(\dfrac{1}{2}x-\dfrac{\pi}{8}\right)-2[/tex].

Kelly wants to plant flowers on the edge of a circular flowerbed around a tree. If the radius of the flowerbed is 2 feet, and she wants to place the
plants approximately 3 feet apart. How many flower plants should she buy?
A
2 flowers
B
3 flowers
D
4 flowers
5 flowers
Answer:
Divide the given diameter by 2 to obtain the radius in feet.
Divide the radius in feet by 3 to obtain the radius in yards.
Square the radius and multiply the result by an approximation of suitable for your required level of precision. This calculation will provide you with the area of the circle in square yards.
Multiply the calculated area by 13 and round to the nearest whole number. (unless you think the hero of this story knows of a nursery that will sell him fractional parts of a plant)
Notes on approximation of for this problem. Either , , or any representation of to greater precision will result in the same number of plants after rounding to the nearest whole number of plants.

Answer:
[tex]x=-15.8994[/tex]
Step-by-step explanation:
Skills needed: Solving one variable equations, Multiplication
1) We are given: [tex]-11.818=-7+\frac{x}{3.3}[/tex], and we need to solve for "[tex]x[/tex]"
2) In order to do this, you need to isolate the variable. In other words, you need to make sure the term involving "[tex]x[/tex]" is on one side of the equation, while everything else is on the other side.
In this case, the term involving "[tex]x[/tex]" is: [tex]\frac{x}{3.3}[/tex] In order to isolate [tex]\frac{x}{3.3}[/tex], you need to get rid of the "-7" on the right side. To get rid of it, we can add 7 to both sides.3) [tex]-11.818+7 = -7+\frac{x}{3.3} +7[/tex]
[tex]-11.818+7=-4.818[/tex]
-7 and 7 on the right side cancel out.
4) So you are left with: [tex]-4.818=\frac{x}{3.3}[/tex]
To get "[tex]x[/tex]", you need to multiply both sides by 3.3If you do this, the denominator will get cancelled out, leaving us with "[tex]x[/tex]" equaling a value.5) So then: [tex]-4.818 * 3.3 = x[/tex] (that star sign in between -4.818 and 3.3 is a multiplication sign)
[tex]-4.818*3.3 = -15.8994[/tex], so [tex]x = -15.8994[/tex]

Table I contains outputs of the function f(x) = b* for some 2 values, and Table Il contains outputs of the
function g(x) = log: (x) for some e values. In both functions, b is the same positive constant.
Fill in the missing values in the tables. If necessary, round your answer to three decimal places.
Table 1: 1.683 Table 2: 9
The missing values in the table will be 11.452.
What is a logarithm?Logarithms are another way of writing exponent. A logarithm with a number base is equal to the other number. It is just the opposite of the exponent function.
The given data from the table;
[tex]\rm f(x)=b^x[/tex]
For the first function;
[tex]\rm b^(0.683)= 3 \\\\ b= 4.995[/tex]
The blank data is found as;
[tex]\rm b^x = 8 \\\\ \rm (4.995)^x = 8 \\\\ x \ log \ 4.995 =8 \\\\ x=11.452[/tex]
Hence the missing values in the table will be 11.452.

Answer:

Step-by-step explanation:
Answer:
#4 - 36
#5 - 2
Step-by-step explanation:
For the first question, #4, I believe you have to just find what both those numbers go into, that's 36, so the 36th customer will get both.
For the second question, #5, all you need to know is how many time 2/3 can go into 2 2/3, then that is your answer. So 2/3 only goes in twice, it almost makes it to three but that doesn;t matter you don't have enough raisins to make it there she can only make two batches with the raisins she has.

Mean and standard deviation of sample proportions
Suppose that 35% of students in a school can sing their national anthem correctly. The music teacher takes an SRS of 30 students from the population of 750 students at the school and finds that 40% of students sampled can sing their national anthem correctly. The teacher plans to take more samples like this. Let p represent the proportion of a sample of 30 students in the school who can sing their national anthem correctly. What are the mean and standard deviation of the sampling distribution of p?

The mean and standard deviation is given by -
μ = 0.35 and σ = 0.09.
What is mean, median and mode in statistics?Mean : The "average" number; found by adding all data points and dividing by the number of data points.Median : The middle number; found by ordering all data points and picking out the one in the middle (or if there are two middle numbers, taking the mean of those two numbers).Mode : The most frequent number—that is, the number that occurs the highest number of times.Given is that suppose that 35% of students in a school can sing their national anthem correctly. The music teacher takes an SRS of 30 students from the population of 750 students at the school and finds that 40% of students sampled can sing their national anthem correctly. The teacher plans to take more samples like this. Let {p} represent the proportion of a sample of 30 students in the school who can sing their national anthem correctly.
The standard deviation is given by → [tex]$\sigma={\sqrt {\frac {\sum(x_{i}-{\mu})^{2}}{N}}}[/tex]where -
{σ} = population standard deviation
{N} = the size of the population
x{i} = each value from the population
{μ} = the population mean
The mean and standard deviation is given by -
μ = 0.35
σ = √(0.35)(0.65)/(30) = 0.48/5.5 = 0.09
σ = 0.09
Therefore, the mean and standard deviation is given by -
μ = 0.35 and σ = 0.09
