Answer:
Step-by-step explanation:
n = 7 so it is:
5(7) - 4
= 35 - 4
= 31.
Each number is two times three less than the previous number.
A sequence is the pattern or rule that guides the creation of a set. The most common sequence are the arithmetic and the geometric sequence.
A sequence that starts with 0 is: 0, -6, -12, -18.....A sequence that starts with 3 is: 3, -3, -9, -15.....The complete question illustrates that we build a sequence of number.
Let the n term of the sequence be [tex]T_n[/tex].
2 times 3 less than the previous number means:
[tex]T_n = T_{n-1} - 2 \times 3[/tex]
Where:
[tex]T_n \to[/tex] The current number
[tex]T_{n-1} \to[/tex] The previous number
Assume the first number starts with 0, the next numbers will be:
[tex]T_2 = 0 - 2 \times 3 = -6[/tex]
[tex]T_3 = -6 - 2 \times 3 = -12[/tex]
[tex]T_4 = -12 - 2 \times 3 = -18[/tex]
So, the sequence is:
0, -6, -12, -18.....
Assume the first number starts with 3, the next numbers will be:
[tex]T_2 = 3 - 2 \times 3 = -3[/tex]
[tex]T_3 = -3 - 2 \times 3 = -9[/tex]
[tex]T_4 = -9 - 2 \times 3 = -15[/tex]
So, the sequence is:
3, -3, -9, -15.....

f(x) = |6x| - 2 ; reflection in y-axis
write a function g whose graph represents the indicated transformation of the graph of f.
Hope this helps you. Thank you....
Using the reflection concept, it is found that the function g is given by:
[tex]g(x) = |6x| - 2[/tex]
-------------------
Reflecting a function f(x) over the y-axis is equivalent to finding a function g(x) defined by: [tex]g(x) = f(-x)[/tex]-------------------
In this question, the parent function is: [tex]f(x) = |6x| - 2[/tex]Reflecting over the x-axis:
[tex]g(x) = f(-x)[/tex]
[tex]g(x) = |6(-x)| - 2[/tex]
[tex]g(x) = |-6x| - 2[/tex]
Modulus is an even function, thus [tex]|-6x| = |6x|[/tex], and:
[tex]g(x) = |6x| - 2[/tex]

compound inequality for x.

Answer:
There are generally 3 methods to solve inequalities
Step-by-step explanation:

First, solve f(x) = 0. There are 2 real roots x1 = 1, and x2 = - 3.
Replace x = 0 into f(x). We find f(0) = - 3 < 0. Therefor, the origin O is located inside the solution set.

The graph of f(x) is an upward parabola (a > 0), that intersects the x-axis at x1 = 1 and x2 = - 3. Inside the interval (-3, 1), the parabola stays below the x-axis --> f(x) < 0.
Therefor, the solution set is the open interval (-3, 1)

The ratio of two numbers is 7:8 .If the first number is 84. Find the second number.
Answer: The second number is 96.
Step-by-step explanation:
Let the second number be x
7/8 = 84/x
or, 7x = 672
or, x = 672/7
so, x = 96
Answer: The second number = 96
Step-by-step explanation:
Given information
Ratio = 7 : 8
First number = 84
Second number = x
Set proportion according to the given information
84 / x = 7 / 8
Cross multiply
7x = 84 × 8
7x = 672
Divide 7 on both sides
7x / 7 = 672 / 7

You offered a SALARY job of $47,603, and you are expected to work 44 hours a week
What would your hourly rate be?
Answer:
$20.81
Step-by-step explanation:
There are 52 weeks in a year.
Let's say you get paid x dollars per hour. Every week, you get paid x dollars for each hour you work. If you work 44 hours, you get paid x * 44 dollars a week. We get paid x * 44 dollars each week for a year, for 52 weeks. We can represent this as (x*44) * 52 = x * 2288. This is the amount you get paid each year. Setting that to your yearly salary of $47,603, we have
$47603 = x * 2288
divide both sides by 2288 to isolate x
x ≈ $20.81

What is s²t-10 if s=-8 and t=[tex]\frac{3}{4}[/tex]
Answer:
38
Step-by-step explanation:
Substitute the given values into the expression
(- 8)² × [tex]\frac{3}{4}[/tex] - 10
= 64 × [tex]\frac{3}{4}[/tex] - 10
= (16 × 3) - 10
= 48 - 10
= 38
Answer:
38
Step-by-step explanation:
When [tex]s^{2}t-10[/tex], s = -8 and t = 3/4
= [tex]-8^{2} \frac{3}{4} - 10[/tex]
= 64[tex]\frac{3}{4}[/tex] - 10
= (16 * 3) - 10
= 48 - 10
= 38
R is between Q and S. If QR = 33.4 and SQ = 80, find RS.
Hi! I'm happy to help!
To solve this problem, we need to find out what part isn't already listed.
We know that The entire line (SQ) is 80, and the part of the line that isn't RS (QR) is 33.4. The rest of the line must be the difference between 80, and 33.4. To find the difference we use subtraction:
80-33.4
44.6
So, RS is 44.6
I hope this was helpful, keep learning! :D
The calculated length of the segment RS is 46.6
How to determine the length of the segment RSFrom the question, we have the following parameters that can be used in our computation:
R is between Q and S.
QR = 33.4 and SQ = 80
using the above as a guide, we have the following:
QR + RS = QS
substitute the known values in the above equation, so, we have the following representation
33.4 + RS = 80
So, we have
RS = 80- 33.4
Evaluate
RS = 46.6
Hence. the length of the segment RS is 46.6
