Answer:
The correct option is;
1, 6, 11, 15
Step-by-step explanation:
The given information are;
The function that defines the terms of the sequence is f(n) = f(n - 1) + 5
Where;
n = The number of the term
For n = 1, we have, f(1) = -4
The first four terms are therefore;
f(2) = f(2 - 1) + 5 = f(1) + 5 = - 4 + 5 = 1
f(3) = f(3 - 1) + 5 = f(2) + 5 = 1 + 5 = 6
f(4) = f(4 - 1) + 5 = f(3) + 5 = 6 + 5 = 11
f(5) = f(5 - 1) + 5 = f(4) + 5 = 11 + 5 = 15
The first four terms are; 1, 6, 11, 15

A town has a population of 12000 and grows at 4% every year. To the nearest year, how long will it be until the population will reach 15600?
Answer:
It will take 7.5 or 7 and a half years for the population to reach 15,600!
Step-by-step explanation:
4% of 12000 is 480!
15600-12000 is 3,600!
3,600/480 is 7.5
Answer:
6.69
Step-by-step explanation:
The equation is:
y=12000(1.04)^x
To solve, set y equal to 15600 and solve for x (I used a calculator)
15600=12000(1.04)^x
x=6.69
Which shows the algebraic representation of the phrase and its value when n=4.27

[
b) How much interest did the class earn on the investment?
Answer:
a is 67.20 and b is 1267.20
Step-by-step explanation:
first you have to multiply 1200 from 5.6% and you get 67.20 then you have to add 1200 to 67.20 and you get 1267.20
How to write a Linear Function??
PLS HELP NOW!
Answer:
i gotchu dude
Step-by-step explanation:
For example, a common equation, y=mx+b y = m x + b , is a linear function because it meets both problems with x and y as variables and m and b as constants.
the steps for writing a linear exp. are
1.) Identify the y-intercept from the graph.
2.)Choose two points to determine the slope.
3.)Substitute the y-intercept and slope into slope-intercept form of a line
.nowww to determine if an equation is a linear function without graphing, you will need to check to see if your function has the characteristics of a linear function. Linear functions are first-degree polynomials. Check that the y, or independent variable, is by itself on one side of the equation.
there are different ways to write linear functions like
1.)f(x) = mx + b (The "slope-intercept" form),
2.)y - yo = m(x - x0) or, equivalently, f(x) = y0 + m(x - x0) (The "point-slope" or "Taylor" form), and.
3.)Ax + By = C (The "general form") which defines y implicitly as a function of x as long as B 0.

The price of a cell phone can be modeled by the equation:
y = 15x + 90, where x is time in years and y is the price of
the phone. This equation tells us that the cell phone originally
cost $90 and each year the cost went up $15. How many years
will it take for the cell phone to cost $150?
Answer:
4 years to cost $150
Step-by-step explanation:
Just add +15 to each year until $150

Solve for AB. Round your answer to the nearest tenth if necessary.
Answer:
AB = 55.25
Step-by-step explanation:
Set up an equation where the length of AB is equal to AC minus BC. This will allow us to solve for x, and then the length of AB.
AB = AC - BC
5x + 9 = 87 - (3x + 4)
5x + 9 = 87 - 3x - 4
5x + 9 = 83 - 3x
8x + 9 = 83
8x = 74
x = 9.25
Now plug 9.25 in for x in the equation for AB
AB = 5x + 9
AB = 5(9.25) + 9
AB = 46.25 + 9
AB = 55.25

What is butterfly method?When using the butterfly method approach, the denominator of the first term is multiplied by the numerator of the second term, and vice versa.
What is proportion?An equation known as proportion shows that the two ratios presented are equal to one another. In other terms, the proportion declares that the two ratios or fractions are equal. In terms of proportion, two sets of supplied numbers are said to be directly proportional if they increase or decrease in the same ratio.
The given proportion is:
[tex]\frac{\frac{1}{2} }{4} = \frac{x}{28}[/tex]
Using the method of cross-product or butterfly method:
[tex]\frac{\frac{1}{2} (28) }{4}=x \\\\\frac{14}{4}=x\\ \\x=3.5[/tex]
The value of x is 3.5. Converting this value into mixed fraction:
3.5 = 3 1/2
Hence, the value of x in the proportion below is option 1 3 1/2.

David made an error when determining the product of (–2.5)(–8.3). Step 1: (–2.5)(–8.3) = (–8.3)(–2.5) Step 2: = (–8.3)(–2) + (–8.3)(–0.5) Step 3: = (–16.6) + (–4.15) Step 4: = –20.75 In which step did David make his first error? Step 1 Step 2 Step 3 Step 4
Answer:
Step 3.
Step-by-step explanation:
We need to tell the incorrect step in the given problem for the product of (–2.5)(–8.3)
Step 1. (–2.5)(–8.3) = (–8.3)(–2.5)
Step 2:
We can write -2.5 = -(2+0.5)
(–8.3)(-(2+0.5)) = (–8.3)(-2)+(-8.3)(-0.5)
= 16.6 + 4.15
Step 3.
= 20.75
He has done an error in step 3. It should be 16.6 + 4.15 instead of (–16.6) + (–4.15). As a result, he get incorrect answer.

An article in the May 2002 issue of "Medicine and Science in Sports and Exercise" reported results of a study that followed 25,892 men aged 30 to 87 for 10 years. The most physically fit men had a 55% lower risk of death from cancer than the least fit group. What is the population of interest and the sample in this scenario? Write your response using complete sentences. plz help
Answer:
In this case the population of interest is the set of all men aged 30 to 87.
In this case the sample is the set of 25,892 men aged 30 to 87.
Step-by-step explanation:
A population is the set of all the data that can be collected and from which a smaller set of data is drawn for further examination. A population may denote to a group of individuals, articles, trials or measurements. A population can thus be called as a collection of information regarding subjects combined together by a common characteristic.
In this case the population of interest is the set of all men aged 30 to 87.
A sample denotes a smaller, controllable form of a larger cluster. It is a subset comprising of the characteristics of a bigger population. Samples are used in statistical experiments when the population under consideration is too large for the test to include all the members.
In this case the sample is the set of 25,892 men aged 30 to 87.
