========================================================
Explanation:
Consider an example like 3, 6, 12, 24, 48, ...
The ratio between consecutive terms is
6/3 = 212/6 = 224/12 = 248/2 = 2Each time we divide any given term over its previous one, we get the same ratio 2. We call this the common ratio. In terms of notation, the variable r is used for the common ratio, so r = 2 in this case.
As another example, the geometric sequence 5, 50, 500, 5000, ... has r = 10 as the common ratio because we multiply each term by 10 to get the next one. Moving forward has us multiply by r, moving backward and we divide by r. The value of r cannot be zero, but it can be negative.
An example with r being negative would be something like
1, -1, 1, -1, 1, -1, ....
we just bounce back and forth between those two values. In this case, r = -1.
Multiply 81.5 and 3.5
Answer:
285.25
Step-by-step explanation:
Basically we multiply them as normal numbers so,
815*35 = 28525
Then we take the amount of spots each number had to the RIGHT of the decimal point
81.5 = 1
3.5 = 1
1+1= 2
So: 28525. move to the left 2 times to get 285.25

Which statement best describe the diagonals of a rhombus?
A) Is a parallelogram with congruent diagonals
B) Is a parallelogram with diagonals that bisects a pair of opposite angles and the diagonals are perpendicular
C) Is a parallelogram with the diagonals that intersect but does not form 90 degree
D) Is a parallelogram with diagonals that are congruent and perpendicular
Answer:
Is a parallelogram with congruent diag............ option is best describing better
The statement which best describes the diagonals of a rhombus is B. Is a parallelogram with diagonals that bisects a pair of opposite angles and the diagonals are perpendicular.
What is Rhombus?A rhombus is a two dimensional shape which consists of four equal sides with opposite side being parallel and opposite angles being equal.
So, rhombus is a parallelogram with all sides being equal.
The diagonals of a rhombus are not of equal length, so they are not congruent.
Also, the two diagonals of a rhombus cuts each other in to two equal halves and the intersecting angle is 90 degrees.
This means that the diagonals of a rhombus are perpendicular bisectors of each other.
Also, the diagonals bisect the pair of opposite angles through which the line passes.
Hence the correct option is B. Is a parallelogram with diagonals that bisects a pair of opposite angles and the diagonals are perpendicular.

Describe the end behavior of the function: y = -2x³ + x4 + 1 A. Even positive B. Odd positive C. Even negative D. Odd negative
Answer:
Even positive
Step-by-step explanation:
Given
[tex]f(x) = -2x^3 + x^4 + 1[/tex]
Required
The end behavior
We have:
[tex]f(x) = -2x^3 + x^4 + 1[/tex]
Rewrite as:
[tex]f(x) = x^4 -2x^3 + 1[/tex]
To describe the end behavior, we check the leading coefficient and the degree of the function.
We have:
Leading Coefficient = 1 (i.e. the coefficient of [tex]x^4[/tex])
Degree = 4 (i.e. the power of [tex]x^4[/tex])
The degree of the function is even (i.e. 4)
The leading coefficient is positive (i.e. 1)
Hence, the end behavior is Even positive

Mr. Blake took 10 minutes to drive 5 miles,
He claims it will take half an hour to drive 15 more miles at the same rate.
Select all the statements that are true if Mr. Blake claim is true.
1. He will travel 2 miles per minute.
2. Hw would travel 50 miles in 25 minutes.
3. He will travel 1 mile for every 2 minutes.
4. He will travel at a rate of 30 miles per hour.
5. The ratio of miles driven to minutes traveled is 1:2.
Answer:
The correct answer is - 3, 4, and 5.
Step-by-step explanation:
Given:
distance = 5 miles
time to cover 5 miles = 10 minutes
If his claim is true then,
additional Distance = 15 miles
total distance will be = 15+5 = 20 miles
additional time = 30 minutes
total time = 10+30 = 40 minutes
Solution:
The speed of the vehicle can be calculated by the formula:
V = d/t
where V is speed or velocity
d = distance
t = time
Putting the final or total values in formula =
V = 20/40
= 1/2 (5th statement is true)
In an hour where 60 minutes are there, 1/2 = 30 miles per hour.
Thus, 3rd and 4th statement are true.

What is the average rate of change for the function f(x)=3x^2 -5 on the interval −3 ≤ x ≤ −1 ?
Answer:
-12
Step-by-step explanation:
Let b = -1 and a = -3
The average rate of change = [tex]\frac{f(b) - f(a)}{b - a}[/tex]
f(b) = f(-1) = 3(-1)^2 - 5 = 3 - 5 = -2
f(a) = f(-3) = 3(-3)^2 - 5 =27 - 5 = 22
f(b) - f(a) = -2 - 22 = -24
b - a = -1 + 3 = 2
[tex]\frac{f(b) - f(a)}{b - a}[/tex] = -24/2 = -12

Here’s the revenue and expenses for the month. Calculate whenever Mia had profit or loss.
Answer:
Profit = $200
Step-by-step explanation:
Total revenue = $9,500
Fixed expenses = $9,000
Variable expenses = $300
Total expenses = Fixed expenses + Variable expenses
= $9,000 + $300
= $9,300
Total expenses = $9,300
Profit is when revenue is greater than expenses
Loss is when revenue is less than expenses
Mia made profit because her revenue is more than her expenses
Profit = Revenue - Expenses
= $9,500 - $9,300
= $200
Profit = $200

The three side lengths of four triangles are given which triangle is a right triangle
Answer:
Triangle 3: 3, 4 ,5
Step-by-step explanation:
Well, you can easily tell by 3, 4, 5 being a Pythagorean triple.
But you have to use the Pythagorean Theorem to solve this.
So you get the side lengths of the two shortest sides, and you add the squared versions of them together.
So: 3^2+4^2 and if that equals the biggest side:5^2 then it's a right triangle.
Ken is thinking of a number. Nine more than the product of 4 & the number is 73. Find Ken's number.
Answer:
x = 16
Step-by-step explanation:
Let the unknown number be x.
Translating the word problem into an algebraic expression, we have;
4x + 9 = 73
4x = 73 - 9
4x = 64
x = 64/4
x = 16
Therefore, the unknown number is 16.
When a child is born, her grandfather decides to put $100 in an account that earns interest. He plans to make no other deposits or withdrawals for 18 years. When the child turns 18 years old, the money in the account will be a birthday gift. The grandfather is choosing between two options:
Option 1: An account that grows by 10.5% each year.
Option 2: An account that grows by $20 each year.
Which option will result in a better 18th birthday gift? Explain your reasoning.
Answer:
option (1) is a better 18th Birthday gift of child by Grandfather.
Step-by-step explanation:
Amount deposited in bank at time of birth by Grandfather is $100.
And there is no other deposits and withdrawals for 18 years.
So,
Principal amount =$100
Time = 18 years
Rate of interest of bank = 10.5%
Option 1:- An account That grows by 10.5% each year
we know that Bank give compound interest on the deposit amount
then Compound interest = C.I=P(1+r) with an exponent of t
C.I= 100(1 + 10.5 over 100)with an exponent of 18
C.I= 100*6.0328
C.I= $603.28
Option 2:- An account that grows by $20 each year
Here,
Amount credited in account for 18 years = $20
So, Total amount after completion of 18 years = 10+18*20
=460
Hope this helped <3
