A rock has a mass of 14 g and a volume of 2 cm3. What is the density of the rock? *
We will determine the density of the rock as follows:
\(\rho=\frac{14g}{2cm^3}\Rightarrow\rho=7g/cm^3\)So, the density of the rock is 7 g/cm^3.
Find the value of x. A: 15 B: 12 C: 10 D: 8
Answer:
\(\boxed{\sf C. \ 10}\)
Step-by-step explanation:
\(\sf The \ intersecting \ chord \ theorem \ states \ that \ the \ products\)
\(\sf of \ the \ lengths \ of \ the \ line \ segments \ on \ each \ chord \ are \ equal.\)
\(NH \times HT = MH \times HY\)
\((x+20) \times 8=12 \times 20\)
\(\sf Expand \ brackets \ and \ multiply.\)
\(8x+160=240\)
\(\sf Subtract \ 160 \ from \ both \ sides.\)
\(8x+160-160=240-160\)
\(8x=80\)
\(\sf Divide \ both \ sides \ by \ 8.\)
\(\displaystyle \frac{8x}{8} =\frac{80}{8}\)
\(x=10\)
The value of x is 10.
We have a circle and inside it two chords MY and NT intersect at point H.
We have to find the value of x in the figure.
What is intersecting chord theorem?According to the intersecting chord theorem, when two chords say AB and CD intersect at point O, then
AO x OB = CO x OD
Applying the chord intersecting theorem to the figure in the question, we get -
MH x HY = NH x HT
12 x 20 = (x+20) x 8
240 = 8x + 160
8x = 80
x = 10
Hence the value of x is 10.

The measure of angle ADC in the geometric system is equal to 55°.
How to determine the value of an angle related to a geometric system
In this question we find a geometric system formed by a quadrilateral and an angle vertical to a vertex of the quadrilateral. Angle CDE is supplementary to angles EDF and ADC. Two angles are supplementary whose sum of measures equals 180°. Therefore:
m ∠ CDE + m ∠ EDF = 180°
(2 · x + 1) + (x - 7) = 180°
3 · x - 6 = 180°
3 · x = 186°
x = 62
m ∠ CDE = 2 · x + 1
m ∠ CDE = 2 · 62 + 1
m ∠ CDE = 125°
m ∠ ADC = 180° - 125°
m ∠ ADC = 55°

Create the letter M in desmos. It must be a BLOCK M and you can use the following:
Polynomial (degree 3 and higher), Rational, Trigonometric and Logarithmic functions. You're also open to use square root functions, exponential functions, and circles.
Make sure that the top of the "M" does not exceed y = 13 and the bottom does not go below y = 1.5 (use this to figure out the size of the M itself).
Answer:
see attached
Step-by-step explanation:
You want a series of functions and their transformations that will develop a graph of a block capital letter "M", using trig functions.
ApproachThe block letter M consists mainly of straight lines. To approximate a straight line, we have elected to use the portion of the sine function in the interval [-π/3, π/3] where it is approximately straight, but shows a hint of the sine function.
First, we created a function that moves that segment of the sine function so it is defined between the points (0, 0) and (1, 1). This makes scaling relatively easy.
Then, we created a function that draws that segment between coordinates (a, b) and (c, d).
Letter MWe used this second function to draw segments between the points we chose for the outline of the left half of the letter.
Finally, we created the right half of the letter by reflecting those functions over the vertical line of symmetry (at x = 4.7). The end result is shown in the first attachment. The function and segment definitions not shown in the first attachment are shown in the second attachment. The f( ) in the Reflection section fills in the horizontal segment between the two halves of the letter.
__
Additional comment
Appending this identifier to the Desmos URL will give you the graph and function definitions we show here. This should eliminate the need to type them, if the result here is suitable.
We have used 13 function definitions that need to be changed if you desire to move the letter to different coordinates or scale it. You could combine these into two piecewise functions (one for the top, one for the bottom), so that translation or scaling could be done more easily.

x - 24 = 40
Now we add 24 on both sides to isolate the x and get all of the numbers on the other side:
x = 64

[~S & (R V S)] ≡ (Q ⊃ S) is true when A = T, S = F, R = F, and Q = T by substituting the propositional variables.
What is truth table?A truth table is a table used to determine the truth values of a compound proposition, which is a logical statement made up of simpler propositions using logical operators such as "and" (represented by "&"), "or" (represented by "V"), "not" (represented by "~"), conditional (represented by "⊃"), and biconditional (represented by "≡").
According to question:Let's substitute the given truth values for the propositional variables in the given statement:
[~F & (F V F)] ≡ (T ⊃ F)
Using the truth table for conjunction (represented by "&") and disjunction (represented by "V"), we can simplify the left-hand side of the equivalence:
[T & F] ≡ (T ⊃ F)
Using the truth table for conditional (represented by "⊃"), we can simplify the right-hand side of the equivalence:
F ≡ F
Since both sides of the equivalence have the same truth value, the statement is true.
Therefore, [~S & (R V S)] ≡ (Q ⊃ S) is true when A = T, S = F, R = F, and Q = T.

Answer:
The answer is the secret beans cost $22.5 per pound.
Step-by Step: Step 1: make an equation. 12 lbs is the secret formula, and the cost in unknown lets put that as x. So 12 lbs +15 lbs of $18 mix which is the coffee beans =$20 per lbs. So the total amount is is 27 lbs. Now lets right the equation. 12x+15(18)=20(27) solve for x normally 12x+270=540 12x=270 x=22.5 SO the final answer is $22.5 I hope this helped.
The baristas secret formula beans cost per pound is $19.2.
What is function?A function is a relation between a dependent and independent variable.
Mathematically, we can write → y = f(x) = ax + b.
Given is that a barista mixes 12 lb of his secret-formula coffee beans with 15 lb of another bean that sells for $18 per lb.
The cost of 1 pound of another bean as -
$(15/18) = $(5/6)
Assume that 1 pound of secret coffee costs ${x}. So, we can write -
x + 5/6 = 20
x = 20 - 5/6
x = 19.2
Therefore, the baristas secret formula beans cost per pound is $19.2.

Step-by-step explanation:
Consider the functions f and g.
Which statement is true about these functions ?
The correct statement regarding the average rate of change of the functions f(x) and g(x) on the interval [-2,2] is given as follows:
Over the interval [-2,2], the function f is increasing at a faster rate than function g is decreasing.
How to obtain the average rate of change?The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.
For the function f(x), the numeric values at x = -2 and x = 2 are given as follows:
f(-2) = (-2)³ + 5(-2)² - (-2) = 14.f(2) = (2)³ + 5(2)² - 2 = 26.Hence the rate is of:
(26 - 14)/(2 - (-2)) = 12/4 = 3. -> positive rate -> increasing.
For function g(x), the rate is given as follows:
(-16 - 4)/4 = -5.

Step-by-step explanation:
This is a bit of a tricky equation, and it's what we call an exponential equation since it involves some exponents. The way we begin to solve these kinds of problems is make the base on each side of the equals sign the same. On one side, we have 9 as our base, and on the other side, we have 3 as our base. 9 = 3², so we can rewrite our equation as shown below:
(3²)⁴ˣ⁻¹⁰ = 3⁵ˣ⁻²
From there, we can use the exponent rule (xᵃ)ᵇ = xᵃᵇ to simplify the left side of the equation.
3²⁽⁴ˣ⁻¹⁰⁾ = 3⁵ˣ⁻²
3⁸ˣ⁻²⁰ = 3⁵ˣ⁻²
Since our bases are now the same, we can take just the exponents and turn it into a new equation as shown below:
8x - 20 = 5x - 2
Hopefully at this point, this problem becomes easy for you, but I'll show how I solved this new equation below in case it doesn't make sense.
8x - 20 = 5x - 2
8x - 20 - 5x = 5x - 2 - 5x
3x - 20 = -2
3x - 20 + 20 = -2 + 20
3x = 18
3x/3 = 18/3

a) We know that 13 cities had soccer and football, 13 had soccer and volleyball, and 7 had all three sports. Therefore, the number of cities that had only 5 soccer.
b) 34 cities had either a soccer team or a football team.
c)27 cities had either a soccer team or a football team, but not a volleyball team.
What is set theory?
(a) To find the number of cities that had only a soccer team, we need to subtract the cities that had soccer and at least one other sport from the total number of cities that had soccer.
From the given information, we know that 13 cities had soccer and football, 13 had soccer and volleyball, and 7 had all three sports. Therefore, the number of cities that had only soccer is:
24 (total cities with soccer) - 13 (cities with soccer and football) - 13 (cities with soccer and volleyball) + 7 (cities with all three sports) = 5
So, 5 cities had only a soccer team.
(b) To find the number of cities that had soccer or football, we need to add the number of cities that had soccer to the number of cities that had football and then subtract the cities that had both soccer and football (which were counted twice).
From the given information, we know that 24 cities had soccer, 23 had football, and 13 had both. Therefore, the number of cities that had soccer or football is:
24 (cities with soccer) + 23 (cities with football) - 13 (cities with both) = 34
So, 34 cities had either a soccer team or a football team.
(c) To find the number of cities that had soccer or football, but not volleyball, we need to subtract the cities that had all three sports from the total number of cities that had soccer or football (which we calculated in part b).
From the given information, we know that 7 cities had all three sports. Therefore, the number of cities that had soccer or football, but not volleyball, is:
34 (cities with soccer or football) - 7 (cities with all three sports) = 27
So, 27 cities had either a soccer team or a football team, but not a volleyball team.
