8. The first three terms of a geometric sequence are ( x-6), 3x, and y. If the common ratio is 6, then the value of y is.
Answer:
The value of y is 216
(and the value of x is 12)
Step-by-step explanation:
The general formula for a geometric sequence is,
\(a_n = a_1(r)^{n-1}\)
Where n represents the nth term, a_1 is the first term and r is the common ratio,
we see that,
r = 6,
the first term is,
a_1 = (x-6)
the 2nd term is,
a_2 = 3x,
the 3rd term is,
a_3 = y, finding y,
first we find x, using the above given formula we have,
\(a_2 = a_1(6)^{2-1}\\3x = (x-6)(6^1)\\3x = 6x -36\\36 = 6x - 3x\\36 = 3x\\x=36/3\\x=12\)
x = 12,
Now, for y we can use the relation between a_3 and a_2,
\(a_3 = a_1(6)^{3-1}\\y = (x-6)(6)^2\\y = (12-6)(6^2)\\y = 6(6^2)\\y = 6^3\\y = 216\)
y = 216

Coco flips a penny, a nickel, and a quarter. Each coin is fair (meaning that heads and tails are equally likely to come up). What is the probability that at least one of the coins comes up heads?
Enter your answer as a fraction in simplified form.
Answer:
7/8
Step-by-step explanation:
Using the binomial distribution, it is found that there is a \(\frac{7}{8}\) probability that at least one of the coins comes up heads.
What is the binomial distribution formula?The formula is:
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
A coin is fair, hence p = 1/2.Three coins are thrown, hence n = 3.The probability that at least one of the coins comes up heads is given by:
\(P(X \geq 1) = 1 - P(X = 0)\)
In which:
\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)
\(P(X = 0) = C_{3,0}.\left(\frac{1}{2}\right)^{0}.\left(\frac{1}{2}\right)^{3} = \frac{1}{8}\)
Then:
\(P(X \geq 1) = 1 - P(X = 0) = \frac{8}{8} - \frac{1}{8} = \frac{7}{8}\)
\(\frac{7}{8}\) probability that at least one of the coins comes up heads.

The formula for the area of a trapezoid is A = 1/2h (b1 + b2), where h is the height of the trapezoid, and b1 and b2 are the lengths of the bases.
Part A: Solve the formula for h. What is the height of a trapezoid that has an area of 91 cm2 and bases of 12 cm and 16 cm?
Part B: What method would you use to solve the formula for b1? What is the formula when solved for b1?
Part C: What is the length of the other base if one base of a trapezoid is 30 cm, the height of the trapezoid is 8.6 cm, and the area is 215 cm2?
Part D: If both bases of a trapezoid have the same length, can you find their lengths given the area and height of the trapezoid? Explain.
Answer:
A) The height of the trapezoid is 6.5 centimeters.
B) We used an algebraic approach to to solve the formula for \(b_{1}\). \(b_{1} = \frac{2\cdot A}{h}-b_{2}\)
C) The length of the other base of the trapezoid is 20 centimeters.
D) We can find their lengths as both have the same length and number of variable is reduced to one, from \(b_{1}\) and \(b_{2}\) to \(b\). \(b = \frac{A}{h}\)
Step-by-step explanation:
A) The formula for the area of a trapezoid is:
\(A = \frac{1}{2}\cdot h \cdot (b_{1}+b_{2})\) (Eq. 1)
Where:
\(h\) - Height of the trapezoid, measured in centimeters.
\(b_{1}\), \(b_{2}\) - Lengths fo the bases, measured in centimeters.
\(A\) - Area of the trapezoid, measured in square centimeters.
We proceed to clear the height of the trapezoid:
1) \(A = \frac{1}{2} \cdot h \cdot (b_{1}+b_{2})\) Given.
2) \(A = 2^{-1}\cdot h \cdot (b_{1}+b_{2})\) Definition of division.
3) \(2\cdot A\cdot (b_{1}+b_{2})^{-1} = (2\cdot 2^{-1})\cdot h\cdot [(b_{1}+b_{2})\cdot (b_{1}+b_{2})^{-1}]\) Compatibility with multiplication/Commutative and associative properties.
4) \(h = \frac{2\cdot A}{b_{1}+b_{2}}\) Existence of multiplicative inverse/Modulative property/Definition of division/Result
If we know that \(A = 91\,cm^{2}\), \(b_{1} = 16\,cm\) and \(b_{2} = 12\,cm\), then height of the trapezoid is:
\(h = \frac{2\cdot (91\,cm^{2})}{16\,cm+12\,cm}\)
\(h = 6.5\,cm\)
The height of the trapezoid is 6.5 centimeters.
B) We should follow this procedure to solve the formula for \(b_{1}\):
1) \(A = \frac{1}{2} \cdot h \cdot (b_{1}+b_{2})\) Given.
2) \(A = 2^{-1}\cdot h \cdot (b_{1}+b_{2})\) Definition of division.
3) \(2\cdot A \cdot h^{-1} = (2\cdot 2^{-1})\cdot (h\cdot h^{-1})\cdot (b_{1}+b_{2})\) Compatibility with multiplication/Commutative and associative properties.
4) \(2\cdot A \cdot h^{-1} = b_{1}+b_{2}\) Existence of multiplicative inverse/Modulative property
5) \(\frac{2\cdot A}{h} +(-b_{2}) = [b_{2}+(-b_{2})] +b_{1}\) Definition of division/Compatibility with addition/Commutative and associative properties
6) \(b_{1} = \frac{2\cdot A}{h}-b_{2}\) Existence of additive inverse/Definition of subtraction/Modulative property/Result.
We used an algebraic approach to to solve the formula for \(b_{1}\).
C) We can use the result found in B) to determine the length of the remaining base of the trapezoid: (\(A= 215\,cm^{2}\), \(h = 8.6\,cm\) and \(b_{2} = 30\,cm\))
\(b_{1} = \frac{2\cdot (215\,cm^{2})}{8.6\,cm} - 30\,cm\)
\(b_{1} = 20\,cm\)
The length of the other base of the trapezoid is 20 centimeters.
D) Yes, we can find their lengths as both have the same length and number of variable is reduced to one, from \(b_{1}\) and \(b_{2}\) to \(b\). Now we present the procedure to clear \(b\) below:
1) \(A = \frac{1}{2} \cdot h \cdot (b_{1}+b_{2})\) Given.
2) \(b_{1} = b_{2}\) Given.
3) \(A = \frac{1}{2}\cdot h \cdot (2\cdot b)\) 2) in 1)
4) \(A = 2^{-1}\cdot h\cdot (2\cdot b)\) Definition of division.
5) \(A\cdot h^{-1} = (2\cdot 2^{-1})\cdot (h\cdot h^{-1})\cdot b\) Commutative and associative properties/Compatibility with multiplication.
6) \(b = A \cdot h^{-1}\) Existence of multiplicative inverse/Modulative property.
7) \(b = \frac{A}{h}\) Definition of division/Result.

(x + 8)² + (y - 8)² = 64=======================
Given ConditionsTangent to x-axis,Tangent to y-axis,In the second quadrant,Radius is 8 units.SolutionEquation of circle:
(x - h)² + (y - k)² = r², where (h, k) is center and r - radiusThe center is the radius long distance from the x- axis to left and y-axis up same distance, this makes it in the second quadrant.
So the coordinates of the center are:
x = - 8, y = 8The equation is:
(x - (-8))² + (y - 8)² = 8²(x + 8)² + (y - 8)² = 64
Answer:
\((x+8)^2+(y-8)^2=64\)
Step-by-step explanation:
Required conditions:
Tangent to both axes.Center in the second quadrant.Radius = 8 units.If the circle is tangent to both axes, its center will be the same distance from both axes. That distance is its radius.
If the center of the circle is in quadrant II, the center will have a negative x-value and a positive y-value → (-x, y).
Therefore, the coordinates of the center will be (0-r, 0+r) where r is the radius.
If the radius is 8 units, then the center is (-8, 8).
\(\boxed{\begin{minipage}{4 cm}\underline{Equation of a circle}\\\\$(x-a)^2+(y-b)^2=r^2$\\\\where:\\ \phantom{ww}$\bullet$ $(a, b)$ is the center. \\ \phantom{ww}$\bullet$ $r$ is the radius.\\\end{minipage}}\)
Substitute the found center and given radius into the formula to create an equation for the circle that satisfies the given conditions:
\(\implies (x-(-8))^2+(y-8)^2=8^2\)
\(\implies (x+8)^2+(y-8)^2=64\)

Answer:
What is a linear function? A linear function is a function whose graph is a straight line. The rate of change of a linear function is constant. The function shown in the graph below, y = x + 2, is an example of a linear function.
Graph of linear function
Graph of linear function
A linear function has a constant rate of change. The rate of change is the slope of the linear function. In the linear function shown above, the rate of change is 1. For every increase of one in the independent variable, x, there is a corresponding increase of one in the dependent variable, y. This gives a slope of 1/1 = 1.
A linear function is typically given in the form y = mx + b, where m is equal to the slope, or constant rate of change.
Examples of linear functions include:
If a person drives at a constant speed, the relationship between the time spent driving (independent variable) and the distance traveled (dependent variable) will remain constant.
Assuming no change in price, the relationship between the number of pounds of bananas a person buys (independent variable) and the total cost of the bananas (dependent variable) will remain constant.
If a person earns an hourly wage at their job, the relationship between the time spent working (independent variable) and the amount earned (dependent variable) will remain constant.

Exponential Functions
What is an exponential function? An exponential function is a function that involves exponents and whose graph is a smooth curve. The rate of change in an exponential function is not constant. The functions shown in the graph below, y = 0.5x and y = 2x, are examples of exponential functions.
Graphs of exponential functions
Graphs of exponential functions
An exponential function does not have a constant rate of change. The rate of change in an exponential function is the value of the independent variable, x. As the value of x increases or decreases, the rate of change increases or decreases as well. Rather than a constant change, as in the linear function, there is a percent change.
An exponential function is typically given in the form y = (1 + r)x, where r represents the percent change.
Examples of exponential functions include:

Is the range a subset or a proper subset of the codomain?
A function's codomain is a subset of its range. Although it is not a true subset, it is conceivable for the range to be equal to the codomain, in which case it is also a subset of the codomain.
What is a subset?A set that includes all or a portion of another set's elements is known as a subset. For instance, because every even integer is also an integer, the set of even integers is a subset of the set of integers. A subset that contains some, but not all, of the members of another set is said to be a proper subset. Because it contains some, but not all, of the positive integers, the set of positive integers less than 10 is a valid subset of the set of positive integers.
