The sequences below is geometric sequences. 8,16,32
Step-by-step explanation:
It is geometric as far as it goes.
Notice that the ratio between each successive pair of terms is constant:
4/2=2
8/4=2
16/8=2
That these ratios are all the same is sufficient for the given terms to form a geometric sequence with general term:
an=[tex]2^{n}[/tex]
The sequence then continues:

What we have here in the picture is a graph of a segment. The goal is to find the segment's length, which we can do by using the distance formula:[tex]d^2=\left(x_2-x_1\right)^2-\left(y_2-y_1\right)^2[/tex].
What is graph?
A graph is a structure that resembles a set of items in discrete mathematics, more especially in graph theory, in which certain pairs of the objects are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.
Note that the distance between two points is equal to the length of the line segment that joins them.
So now we already have answers for two of the boxes.
The difference in the x-coordinates gives us the horizontal distance between the two points, while the difference in the y-coordinates gives us the vertical distance between the points.

The equation of the line is y = -1/2x + 7 which passes through the point (2, 6) and has a slope of -1/2.
What is the equation of a line?
The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis. Key Point. The equation of a straight line with gradient m and intercept c on the y-axis is y = mx + c.
The equation of a line that passes through the point (2, 6) and has a slope of -1/2 can be written in the form y = mx + b, where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.
To find the equation of the line, we can use the point-slope form of a line, which is given by the equation y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line.
Substituting the values for the point and the slope into this equation, we get:
y - 6 = (-1/2)(x - 2)
y - 6 = -1/2x + 1
y = -1/2x + 7

Jill made a New Year's resolution to learn how to play the cello. She bought an Introduction to
Cello class pack from the Purple Harp music shop, which covers the cost of 15 cello lessons.
She also paid $35 to rent a cello. In all, Jill paid $425.
Which equation can you use to find the cost, c, of each cello lesson?
A. 35(c +15) = 425
B. 15c + 35 = 425
C. 15(c + 35) = 425
D. 35c+15= 425
Answer: The correct equation to find the cost, c, of each cello lesson is: 15c + 35 = 425
Step-by-step explanation:
This equation represents the total cost of the cello lessons and the cello rental, which is 425 dollars. The cost of the cello lessons is represented by 15c, and the cost of the cello rental is represented by 35 dollars. By solving this equation for the variable c, we can find the cost of each cello lesson.
To solve this equation, we can use the following steps:
Subtract 35 from both sides of the equation: 15c = 425 - 35
Simplify the right side of the equation: 15c = 390
Divide both sides of the equation by 15: c = 390/15
Simplify the right side of the equation: c = 26
Therefore, the cost of each cello lesson is $26.

Michelle invests in a savings account that pays 5% interest compounded monthly. What is the APY for this account ?? (Round to the nearest 0.00%)
Only answer if you know!!
The account's APY is 5.12%.
Waht is APY.Annual Percentage Yield, or APY, is the rate that may be earned on an account over the course of a year and includes compound interest.
The annual percent yield, or APY, accounts for interest compounding. Because it takes into account the interest you earn on your money, it accurately reflects the interest rate you really receive on an investment.
Consider the previous illustration, where a $100 investment generates a 5% quarterly compounded return. On the $100, you receive interest throughout the first quarter. However, in the second quarter, you also receive interest on the $100 in addition to the first quarter's interest.
The APY (Annualized Percentage Yield) formula is:
APY = [tex](1+i/N)^{N} -1[/tex]
where, i = Nominal rate = 5%, N = Number of compounding periods = 12
putting the values in the above formula, we get,
APY = (1 + 5% / 12)^12 - 1
APY = (1 + 0.4167%)^12 - 1
APY = (1 + 0.0041667)^12 - 1
APY = (1.0041667)^12 - 1
APY = 1.051161897 - 1
APY = 0.051161 or 5.12%

10 Find the value of CB
A. 10.5cm
B. (20/7)√58 cm
C. 21/2 cm
D. None of these
Answer:
Option A
Step-by-step explanation:
(x + 7)2 = 102 + (x + 3)2
(Tangents from the external point are equal)
⇒ x = 7.5cm ⇒ OB = x + 3 = 10.5 cm
Line q passes through the points (3,5) and (-2,4)
10) The second pair of coordinate on the line parallel to q and passes through the point (1, 0) is (-5, 0).
11) The second pair of coordinate on the line perpendicular to q and passes through the point (3, 5) is (2, 0).
What is a slope?When the ratio is expressed as a quotient ("rise over run"), the same number is provided for every two distinct locations on the same line. There is a negative "rise" on a descending line.
Given,
Line q passes through (3, 5), (-2, 4)
(y-y₁)=m(x-x₁)
(y-5)=((4-5)/(-2-3))(x-3)
(y-5)=(-1/-5)(x-3)
-5y+25=-x+3
x-5y+22=0
10) Given point is (0,1)
Slopes are equal for parallel lines.
So, (y-1)/(x-0)=(-1/-5)
-5y+5= -x
x-5y+5=0Let y=0 then,
x= -5
Therefore, the second pair of coordinate on the line parallel to q and passes through the point (1, 0) is (-5, 0).
11) The equation of a line perpendicular to q is,
(y-y₁)=(-1/m)(x-x₁)
(y-5)=5(x-3)
y-5=5x-15
5x-y-10=0
Let y=0 then,
5x-10=0
x=2
Therefore, the second pair of coordinate on the line perpendicular to q and passes through the point (3, 5) is (2, 0).

We can solve this question by using Pythagoras Theorem . The value of x in the given question is 8√3.
What do you mean by Pythagoras Theorem?
The well-known Pythagorean Theorem, which states that the square of the hypotenuse is equal to the sum of squares of the lengths of the other two sides of the right-angled triangle, states that the square on the hypotenuse (the side opposite the right angle) is equal to the square on the legs of a right triangle. Pythagorean Theorem is written as a2 + b2 = c2. Alternatively, the square of the hypotenuse of a right triangle is equal to the sum of the squares of its two legs.
CalculationFrom the given triangle using Pythagoras theorem,
Assume the triangle as ABC where AB=y BC=z and AC=28
D is the altitude from B and BD=x
AD=12 so CD=16
Now using Pythagoras theorem,
(y)2 = (12)2 + (x)2 - eq1
(z)2 = (x)2 + (16)2 -eq2
(y)2 + (z)2 =(28)2 -eq3
Substitute eq 1 and 2 in 3

[tex]\implies t^2-10t+6-6=7-6[/tex]
[tex]\implies t^2-10t=1[/tex]
Add the square of half the coefficient of the term in x to both sides to form a perfect square trinomial on the left side:
[tex]\implies t^2-10t+\left(\dfrac{-10}{2}\right)^2=1+\left(\dfrac{-10}{2}\right)^2[/tex]
Simplify:
[tex]\implies t^2-10t+\left(-5\right)^2=1+\left(-5\right)^2[/tex]
[tex]\implies t^2-10t+25=1+25[/tex]
[tex]\implies t^2-10t+25=26[/tex]
Factor the perfect square trinomial on the left side:
[tex]\implies (t-5)^2=26[/tex]
Square root both sides:
[tex]\implies \sqrt{(t-5)^2}=\sqrt{26}[/tex]
[tex]\implies t-5=\pm \sqrt{26}[/tex]
Add 5 to both sides:
[tex]\implies t-5+5=\pm \sqrt{26}+5[/tex]
[tex]\implies t=5 \pm \sqrt{26}[/tex]
Therefore, the solutions of the given quadratic equation are:
[tex]t=5 +\sqrt{26}, \quad t=5-\sqrt{26}[/tex]

A certain statistic dˆ is being used to estimate a population parameter d. The expected value of dˆ is not equal to d. What property does dˆ exhibit?.
According to the Central Limit Theorem for proportions, the property does dˆ exhibit is the statistic is biased.
Central line theorem:
In statistics, central limit theorem states that when the large sample size has a finite variance, the samples will be normally distributed and the mean of samples will be approximately equal to the mean of the whole population.
Given,
A certain statistic dˆ is being used to estimate a population parameter d. The expected value of dˆ is not equal to d.
Here we need to find the property does dˆ exhibit.
As per the Central Limit Theorem establishes that for a proportion p in a sample of size n:
Expected value μ = p
Standard error s = √p(1 - p) /n
Here the expected value is different of the expected, hence, the statistic is biased.
