For the following geometric sequence, find the recursive formula.
(-80,20,-5...)
Answer:
For the geometric sequence, it has two forms of formula
We are interested in the recursive formula now
{-80, 20, -5, ...}
The common ratio is (20/-80)=(-5/20)=-1/4=-0.25
So our recursive formula would bea_n=a_{n-1}*(-0.25)=a_{n-1}*(- \frac{1}{4} )an=an−1∗(−0.25)=an−1∗(−41)
Step-by-step explanation:
For the geometric sequence, it has two forms of formula
{-80, 20, -5, ...}
The common ratio is (20/-80)=(-5/20)=-1/4=-0.25
So our recursive formula would be a n=a {n-1}*(-0.25)=a_{n-1}*(- \frac{1}{4} )an=an−1∗(−0.25)=an−1∗(−41)
What is the line of symmetry for the parabola whose equation is y = -x2 + x + 3?
x = -1
x = -1/2
x = 1/2
Answer:
[tex]x = \frac{1}{2}[/tex]
Step-by-step explanation:
Given
[tex]y = -x^2 + x + 3[/tex]
Required
The line of symmetry
This is calculated using:
[tex]x= -\frac{b}{2a}[/tex]
Where:
[tex]y = ax^2 + bx + c[/tex]
So, by comparison:
[tex]a = -1[/tex] [tex]b = 1[/tex] [tex]c = 3[/tex]
So, we have:
[tex]x = -\frac{1}{2 * -1}[/tex]
[tex]x = -\frac{1}{-2}[/tex]
[tex]x = \frac{1}{2}[/tex]
1/2 is correct, the formula to use is x= - b/2a :)

The graph of the function f(x) = 4 over 5 square root x is shown. What is the domain of the function?
Answer:
all real numbers greater than or equal to 0
Step-by-step explanation:
The domain of the function is whatever the input (in this case, x) can be. As you cannot take the square root of a negative number, x cannot be negative. Because you can take the square root of 0 (which is 0), x can be anything postive or 0, meaning anything greather than or equal to 0. The domain is all real numbers greater than or equal to 0.
Your answer in part (b) read "one and one- fourth" is called a mixed number since it has a whole number part and a fraction part. What does the word "and" indicate in the name of this fraction?
9514 1404 393
Answer:
the end of the whole number and the beginning of the fraction
Step-by-step explanation:
The word "and" means the whole part and the fractional part should be considered together as having a value equal to their sum. It signifies the separation between the whole-number part and the fractional part.

Determine the solution for the following equation: [tex](8x-8)^{\frac{3}{2} }=64[/tex]
a - x=3
b - x=5
c - 13
d - 65
Answer:
[tex]\text{A. }x=3[/tex]
Step-by-step explanation:
Recall the exponent property [tex]a^{b^c}=a^{(b\cdot c)}[/tex]. Therefore, we can square both sides of the equation to get rid of the fraction in the exponent:
[tex]((8x-8)^{\frac{3}{2}})^2=64^2,\\(8x-8)^{\frac{3}{2}\cdot2}=64^2,\\(8x-8)^3=4096[/tex]
Take the cube root of both sides:
[tex]8x-8=16[/tex]
Add 8 to both sides:
[tex]8x=24[/tex]
Divide both sides by 8 to isolate [tex]x[/tex]:
[tex]x=\frac{24}{8}=\boxed{3}[/tex]

√45 is the distance between which of the following complex numbers?
Step-by-step explanation:
we don't see the complex numbers.
so, we cannot check their distances.
a suspicion, though.
sqrt(45) a distance between 2 complex numbers is
sqrt(a² + b²).
so,
a² + b² = 45
a nice combination of whole square numbers would be 6 and 3.
6² + 3² = 36 + 9 = 45
if that is the case, then that would mean one of the following committed numbers
6 + 3i
3 + 6i
-6 + 3i
6 - 3i
-6 - 3i
-3 + 6i
3 - 6i
-3 - 6i
one of these numbers must be the result of the subtraction of the 2 provided complex numbers.
remember
(a + bi) - (c + di) = a-c + (b-d)i

Engineers must consider the diameters of heads when designing helmets. The company researchers have determined that the population of potential clientele have head diameters that are normally distributed with a mean of 6.6-in and a standard deviation of 1.1-in. Due to financial constraints, the helmets will be designed to fit all men except those with head diameters that are in the smallest 0.8% or largest 0.8%.1. What is the minimum head breadth that will fit the clientele?
2. What is the maximum head breadth that will fit the clientele?
Answer:
1. The minimum head breadth that will fit the clientele is of 3.95-in.
2. The maximum head breadth that will fit the clientele is of 9.25-in.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 6.6-in and a standard deviation of 1.1-in.
This means that [tex]\mu = 6.6, \sigma = 1.1[/tex]
1. What is the minimum head breadth that will fit the clientele?
The 0.8th percentile, which is X when Z has a p-value of 0.008, so X when Z = -2.41.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-2.41 = \frac{X - 6.6}{1.1}[/tex]
[tex]X - 6.6 = -2.41*1.1[/tex]
[tex]X = 3.95[/tex]
The minimum head breadth that will fit the clientele is of 3.95-in.
2. What is the maximum head breadth that will fit the clientele?
The 100 - 0.8 = 99.2nd percentile, which is X when Z has a p-value of 0.992, so X when Z = 2.41.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2.41 = \frac{X - 6.6}{1.1}[/tex]
[tex]X - 6.6 = 2.41*1.1[/tex]
[tex]X = 9.25[/tex]
The maximum head breadth that will fit the clientele is of 9.25-in.
In a certain region, about 11% of a city's population switches from phone service provider APP to phone service provider BPP each year, and about 5% of the populaton switches from BPP to APP each year. Show the system of linear equations that models this migration pattern to calculate the new amounts of the population with each service provider. In 2018, there were 1.75 million customers of APP and 2.05 million customers of BPP. Find the predicted number of customers for each provider in 2022. Round to the nearest hundredth of a million when reporting the populations.
Answer:
The predicted number of customers for APP in 2022 is of 1.37 million, and of BPP is of 2.59 million.
Step-by-step explanation:
Exponential function:
An exponential function has the following format:
[tex]y(t) = y(0)r^t[/tex]
In which [tex]y(0)[/tex] is the initial value and r is the rate of change.
11% of a city's population switches from phone service provider APP to phone service provider BPP each year, and about 5% of the populaton switches from BPP to APP each year.
This means that each year, the BPP amount increases by 11 - 5 = 6%, and the APP decreases by 6%. So the equations are:
BPP:
[tex]B(t) = B(0)(1 + 0.06)^t[/tex]
[tex]B(t) = B(0)(1.06)^t[/tex]
APP:
[tex]A(t) = A(0)(1 - 0.06)^t[/tex]
[tex]A(t) = A(0)(0.94)^t[/tex]
In 2018, there were 1.75 million customers of APP and 2.05 million customers of BPP.
This means that [tex]A(0) = 1.75, B(0) = 2.05[/tex]
Thus
[tex]B(t) = 2.05(1.06)^t[/tex]
[tex]A(t) = 1.75(0.94)^t[/tex]
Find the predicted number of customers for each provider in 2022.
2022 - 2018 = 4, so we have to find A(4) and B(4).
[tex]B(4) = 2.05(1.06)^4 = 2.59[/tex]
[tex]A(4) = 1.75(0.94)^4 = 1.37[/tex]
The predicted number of customers for APP in 2022 is of 1.37 million, and of BPP is of 2.59 million.

If a customer will receive a series of markdowns including 40% off, 25%, and 10% off, the final price of a pair of shoes costing $67.50 will be ?
Answer:
$10
Step-by-step explanation:
In other words, a 25% discount for an item with original price of $40 is equal to $10 Amount Saved Supose Have you received a amazon promotional code of 25 percent of discount.
The final price of the shoe after a series of discounts will be $27.33.
What is a percentage?The Percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that a customer will receive a series of markdowns including 40% off, 25%, and 10% off, the original price is $67.50.
The remaining price will be 60%,75%, and 90% after discounts. Then the final price of the product will be:-
Final price = 67.50 x 0.6 x 0.75 x 0.9
Final price = $27.33
Therefore, the final price of the shoe after a series of discounts will be $27.33.

If H0 is rejected for an analysis of variance, what can we conclude?
a. We can conclude that all the population means have the same value.
b. We can conclude that at least one of the population proportions has a different value.
c. We can conclude that at least one of the population means has a different value than the other population means.
d. We can conclude that all the population means have different values.
Answer: We can conclude that at least one of the population means has a different value than the other population means.
Step-by-step explanation:
When the null hypothesis is rejected for an analysis of variance, we can then conclude that at least one of the population proportions has a different value.
For one-way analysis of variance, it should be noted that the null hypothesis is rejected when there is sufficient evidence which is used in making the conclusion that not all the means are equal and that there is a different value.

ou are setting up a part-time business with an initial investment of $21,000. The unit cost of the product is $11.60, and the selling price is $20.00. (a) Find equations for the total cost C (in dollars) and total revenue R (in dollars) for x units.
Answer:
Total Cost, C(x) = 21000 + 11.60x
Revenue, R(x) = 20(x)
Step-by-step explanation:
Given the investment, which is fixed cost = $21000
Per unit cost of product = $11.60
Selling price = $20
Total cost is the sum of fixed cost and the variable cost:
Thus, TC = FC + VC
Let the number units = x
C(x) = 21000 + 11.60x
Now the total revenue:
R(x) = 20(x)
