The first term of a geometric series is -3, the common ratio is 6, and the sum of the series is -4, 665. Using a table of values, how many terms
are in this geometric series?
OA 6
OB. 5
OC. 10
OD. 4
This geometric progression has 5 terms
This is a geometric progression or geometric series whose sum of n terms is given by the formula
Sn = a[([tex]r^{n\[/tex] – 1)/(r – 1)]
Where Sn is sum of n terms of geometric progression, a is the first term of the series , r is the common ratio
Here we are required to find the number of terms in the geometric progression whose first term is -3 and common ratio is 6
-4665 = -3 [( [tex]6^{n}[/tex]-1)/(6-1)
1555=( [tex]6^{n}[/tex]-1)/5
7775= [tex]6^{n}[/tex]- 1
7776 = [tex]6^{n}[/tex]
[tex]6^{5}[/tex] = [tex]6^{n}[/tex]
So, n=5
Therefore this geometric progression has 5 terms

Which table represents a linear function?
A student performs several experiments in which he swings a pendulum for 20-second duration. He uses a string that is 27 cm long, and he tests pendulum masses of different sizes, varying from 2 to 12 grams. He records the number of swings each pendulum makes in 20 seconds. What is the independent quantity and the dependent quantity.Be sure to include the appropriate units of measure
Using it's concepts, we have that:
The independent variable is the pendulum mass.The dependent variable is the number of swings.What is the relation between a function and the dependent and independent variables?A function has the following format: y = f(x).
In which each value of y is a function of one value of x, and thus, x is the independent variable and y is the dependent variable.
That is, the input of the function is the independent variable and the output is the dependent variable.
For this problem, we have that the number of swings is dependent on the mass of the pendulum, hence:
Number of Swings = f(mass).
Thus:
The independent variable is the pendulum mass.The dependent variable is the number of swings.More can be learned about dependent and independent variables at https://brainly.com/question/1429012

Division is one among the four basic operations of arithmetic, the ways in which numbers are combined to make new numbers. the opposite operations are addition, subtraction, and multiplication.
At an elementary level the division of two natural numbers is, among other possible interpretations, the method of calculating the number of times one number is contained within another.7 This number of times needn't be an integer. for instance , if 20 apples are divided evenly between 4 people, everyone receives 5 apples (see picture).
The division with remainder or Euclidean division of two natural numbers provides an integer quotient, which is that the number of times the second number is completely contained in the first number, and a remainder, which is that the part of the first number that remains, when within the course of computing the quotient, no further full chunk of the dimensions of the second number can be allocated. for instance , if 21 apples are divided between 4 people, everyone receives 5 apples again, and 1 apple remains.
For division to always yield one number instead of a quotient plus a remainder, the natural numbers must be extended to rational numbers or real numbers.

consider a sample with data values of 28, 26, 24, 15, 30, 34, 20, and 26. compute the range. 19 correct: your answer is correct. compute the interquartile range. 14 incorrect: your answer is incorrect. compute the sample variance. (round your answer to two decimal places.) 34.6 correct: your answer is correct. compute the sample standard deviation. (round your answer to two decimal places.) 5.9 correct: your answer is correct.
According to the given statement the values are:
The range = 19
Interquartile Range will be = 8.25
Sample Variance =33.93
Sample Standard deviation = 5.82
What is Interquartile Range?The dispersion of your data's middle quartile is measured by the interquartile range (IQR). It is the range for your sample's middle 50%. Assess geographical variability where the majority of your numbers are by using the IQR. Larger numbers suggest a wider dispersion of your data's center region.
According to the given data:
finding the range = Maximum value + Minimum value
= 34 - 15
= 19
The range = 19When ordering the observations, we obtain:
15,20,24,26,26,27,30,34
Where ,
n = 8
Q1=(n+14)the observation's term value
=(94)the observation's term value
=(2.25)the observation's term value
=2nd observation +0.25[3rd-2nd]
=20+0.25[24-20]
=20+0.25(4)
=20+1
=21
Q3=(3(n+1)4)the observation's term value
=(3⋅94)the observation's term value
=(6.75)the observation's term value
=6th observation +0.75[7th-6th]
=27+0.75[30-27]
=27+0.75(3)
=27+2.25
=29.25
Now finding the Interquartile Range
= Q3 -Q1
= 29.25 - 21
=8.25
The Interquartile Range will be = 8.25
Sample Variance S2=∑x2-(∑x)2nn-1

42. (a) find the unit vectors that are parallel to the tangent line to the curve y − 2 sin x at the point sy6, 1d. (b) find the unit vectors that are perpendicular to the tangent line. (c) sketch the curve y − 2 sin x and the vectors in parts (a) and (b), all starting at sy6, 1d.
Vectors is a quantity that has both magnitude and direction as well. A vector that has 1 magnitude is called unit vector. Unit vector is represented by the symbol '^'.
To find a Unit vector we divide the vector by its magnitude.
First find the slope of the tangent line, slope of a tangent line for a point f(x) is given by f'(x). Hence at point (π/6,1) where x = π/6, the slope of the tangent line is :
[tex]f(x)=2sinx\\f'(x)=2cosx\\f'(\pi /6)=2cos(\pi /6)=2.\frac{\sqrt{3} }{2}=\sqrt{3}[/tex]
The slope of the tangent line at this point is [tex]m=\sqrt{3}[/tex]
Finding a unit vector parallel to the tangent line. since slope is the ratio y and x then we can set an arbitrary vector with slope 4 by letting x=1 and y = √3 or v=[1,√3]. this vector has slope √3 and this is parallel to the tangent line, However this is not unit vector because its magnitude is not equal to 1 so we can divide this vector by its magnitude to find the unit vector.
[tex]u_v=\frac{v}{|v|} =\frac{1 \sqrt{3} }{\sqrt{1^{2}+(\sqrt{3})^2 } } \\=\frac{1}{\sqrt{4} } ,\frac{\sqrt{3} }{\sqrt{4} } =\frac{1}{2}, \frac{\sqrt{3} }{2} =[\frac{1}{2},\frac{\sqrt{3} }{2} ][/tex]
If a line has slope of m then all lines perpendicular of it will have a slope of -1/m
So we are looking for a unit vector of slope of -1/√3
Using the same logic we have unit vector that are perpendicular to the tangent line are [tex][\frac{\sqrt{3} }{2},-\frac{1}{2} ][/tex]

A. The integer that represents the change of altitude to avoid the storm is 8,000
B. The integer representing the altitude after passing the storm is 30,000
How to illustrate the information?A. We are given that the initial altitude of the plane was 30,000 ft. The plane flew at at altitude of 38,000 feet
Change of altitude = final altitude - initial altitude
Change of altitude = 38,000 - 30,000 = 8,000 ft
Therefore, the integer representing the change of altitude to avoid the storm is 8,000
B. After the storm:
We know that, after the storm, the plane returned to its initial altitude. Given that the initial altitude is 30,000 ft, this would mean that the integer representing the altitude after passing the storm is 30,000
