Answer:
A n+1 / A n the ratio of successive terms will be less than 1 if A is between -1 and 1 so successive terms will have a ratio less than 1 and can be determined
If A n+1 / A n > 1 then successive values of the given ratio will not approach a constant value
If you write the value of the nth term as L = a r^(n - 1) one can see that r^(n - 1) approaches a fixed value if r between -1 and 1 but not if | r | > 1

When x4
calculate the median of 2,7,10,8,9,10,15
please do it step by step
Answer: 9
Concept:
The median is the value separating the higher half of a data sample, a population, or a probability distribution, from the lower half.
In other words, the median of a set of data is the middlemost number or center value in the set.
Solve:
STEP ONE: Line up the terms in the set from least to most
Given = 2, 7, 10, 8, 9, 10, 15
Line up = 2, 7, 8, 9, 10, 10, 15
STEP TWO: Find the middlemost number
Given = 2, 7, 8, 9, 10, 10, 15
Since it is an odd set, therefore there should be the equal number of terms in the lower and higher half.
There are in total seven terms, therefore, the 4th term would be the middlemost, which is [tex]\boxed{9}[/tex].
Hope this helps!! :)

Jim and Em baked 33 macaroons.
Jim baked 5 more macaroons than Em. How manymacaroons did Jim bake?
Answer: 19 macaroons
Step-by-step explanation:
Let's create an equation to represent this situation. Let x represent the number of macaroons that Em made.
33=x+x+5
33=2x+5
33-5=2x+5-5
28=2x
28/2=2x/2
14=x
This means that Em made 14 macaroons.
14+5=19
Therefore, Jim baked 19 macaroons.

Answer:

Step-by-step explanation:
-2(2x + 4) + 10 = 8x + 14
-4x - 8 + 10 = 8x + 14

Answer:
first triangle (to left) b=8, second one c=17
Step-by-step explanation:
for the first triangle (one to the left) the hypotenuse is 9, so let's use the pythagorean formula.
A^2 + B^2 = C^2
^ ^ ^
^ ^ Hypotenuse
^ second side
first side
Substitute:
5^2 + b^2 = 9^2
SImplify:
25+b^2 = 81
Reduce:
b^2 = 64
Simplify:
b=8
In the second triangle, we are given 2 sides.
Let's do the same thing we did in the first one.
Givens:
A = 8
B = 15
Find:
C
Substitute:
8^2 + 15^2 = c^2
Simplify
64 + 225 = c^2
Reduce:
289 = c^2
Let's now square root both sides
square root of 289 is 17
so we are left with this:
c=17
Phew, you did it!

A boat can travel 333 miles on 37 gallons of gasoline. How much gasoline will it need to go 486 miles?
Answer:
TRFCCFEDF
Step-by-step explanation:
YHGR
Work Shown:
(distance)/(gallons used) = (distance)/(gallons used)
(333 miles)/(37 gallons) = (486 miles)/(x gallons)
333/37 = 486/x
333x = 37*486 .... cross multiplication
333x = 17,982
x = (17,982)/333
x = 54 gallons
You need 54 gallons to travel 486 miles.

what is 640 divided by 20
Answer:
640/20 is 32
hope it's helpful
When the number 640 is divided by the number 20, the result is 32.
To divide 640 by 20, we perform long division or use the concept of division as the inverse of multiplication. By dividing 640 by 20, we are essentially finding how many times 20 can be evenly divided into 640.
On Dividing 640 by 20 yields a quotient of 32. This means that 20 can be divided into 640 exactly 32 times, without any remainder.
Thus, 640 divided by 20 is equal to 32. In simpler terms, if we distribute 640 items into 20 groups, each group will contain 32 items.

Which statement is true when describing the absolute value of the point represented on the number line?
A) The absolute value of 7 is −7 because the number is seven units to the right of zero on the number line
B) The absolute value of 7 is positive 7 because the distance from zero to 7 on the number line is seven units.
C) The absolute value of 7 is −7 because zero is seven units to the left of 7 on the number line...
D) The absolute value of 7 is −3 because the number is 3 units to the left of 10 on the number line.
What is the absolute value of −9 on the number line?

The absolute value of 7 is positive 7 because the distance from zero to 7 on the number line is seven units.
The absolute value of -9 on the number line will be 9 units from zero.
Explanation:
The absolute value of a real number is only the number irrespective of its sign. For example: The absolute value of '6 is '6' and the absolute value of '-8 ' is 8.The absolute value of a number can also be thought of as the distance from zero along the number line of a real number.Given :
1) Four statements describing absolute value.
2) The absolute value of -9 on a number line.
To find:
1) The true statement.
2) The absolute value of -9 on the number line.
Solution:
1)
The absolute value of a number can also be thought of as the distance from zero along the number line of a real number.
|7|=7
The absolute value of '7' is 7.
This is because the distance from zero to 7 on the number line is seven units.
The statement B is true.
2)
The absolute value of -9:
|-9|=9
The absolute value of -9 on the number line will be 9 units from zero.

Write f(x) = 2x2 – 44x + 185 in vertex form.
To write f(x) = 2x2 – 44x + 185, factor out
from the first two terms.
Next, form a perfect square trinomial keeping the value of the function equivalent:
f(x) = 2(x2 – 22x + 121) + 185 – 242
The function written in vertex form is f(x) =
(x –
)2 +
.
Answer:
Step-by-step explanation:
[tex]f(x)=2x^2-44x+185\\\\=2(x^2-2*11*x)+185\\\\=2(x^2-2*11*x+11^2)+185-2*121\\\\\boxed{f(x)=2(x-11)^2-57}\\\\vertex\ is\ (11,-57)[/tex]
Answer:
f(x) = 2(x - 11)² - 57
Step-by-step explanation:
Given
f(x) = 2x² - 44x + 185 ( factor out 2 from the first two terms )
f(x) = 2(x² - 22x) + 185
To complete the square
add/ subtract ( half the coefficient of the x- term )² to x² - 22x
f(x) = 2(x² + 2(- 11)x + 121 - 121 ) + 185
= 2(x - 11)² + 2(- 121) + 185
= 2(x - 11)² - 242 + 185
f(x) = 2(x - 11)² - 57 ← in vertex form
