Answer:
The key features that are unique to the graphs of sequences and series are that they are discrete.
Explanation:
That means that the graph is not a continuous line or curve that joins all the points. On the contrary, the graph is a set of separated dots, because the values are valid only for specific points.

What percent of 6 is 9?
Answer:
150%
Step-by-step explanation:
half of 6 is three, and 9 has a value of 3 more than 6. meaning that 9/6 = 150%
Answer: [tex]150[/tex]% [tex]([/tex][tex]0.54[/tex][tex])[/tex]
Step-by-step explanation:
For fraction: divide 6 by 100 and remove the % sign.
{[tex]6[/tex]}% [tex]=\frac{6}{100}[/tex]
For decimal: move the decimal point 2 places to the left and remove the % sign.
{[tex]6[/tex]}% [tex]=0.06[/tex]
[tex]100[/tex]% [tex]=9[/tex]
[tex]\frac{6}{100}[/tex] × [tex]9=0.06[/tex] × [tex]9=0.54[/tex]

What is the simplified value of the exponential expression 16 superscript one-fourth? 2 4
For the exponential expression, [tex]16^{1/4}[/tex] the simplified value is 2.
How to simplify the exponential expression?
First, we need to remember a rule for exponential expressions, it says that:
[tex]x^{1/n} = \sqrt[n]{x}[/tex]
Then we can rewrite the given exponential expression as:
[tex]16^{1/4} =\sqrt[4]{16}[/tex]
So, we just need to find a number that when multiplied by itself 4 times, is equal to 16.
We know that:
2*2 = 4
Then:
2*2*2*2 = 2⁴ = 4*4 = 16
Then we can conclude that:
[tex]16^{1/4} =\sqrt[4]{16} = 2[/tex]
So the simplified value of the exponential expression is 2.

Step-by-step explanation:
If the number of bacteria in a colony doubles every 475 hours and there is currently a population of 65 bacteria, what will the population be 950 hours from now???
The population (number of bacteria in the colony), 950 hours from that time, will be 260 bacteria
Determining the population of bacteriaFrom the question, we are to determine what the population will be after 950 hours
From the given information,
The number of bacteria in a colony doubles every 475 hours
The current population is 65 bacteria
∴ After 475 hours, the new population will be 2 × 65 bacteria
New population after 475 hours = 130 bacteria
After another 475 hours (that is, 950 hours from the initial time),
The population will be 2 × 130 bacteria = 260 bacteria
Hence, the population, 950 hours from that time, will be 260 bacteria

What is the slope of a line parallel to the line whose equation is x + y = -7. Fully
simplify your answer.
Answer:
slope = - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
x + y = - 7 ( subtract x from both sides )
y = - x - 7 ← in slope- intercept form
with slope m = - 1
Parallel lines have equal slopes
then the slope of a line parallel to it is - 1

Answer:

Second term : a₂ = 2(a₁ + 4)
a₂ = 2(5 + 4) = 2(9) = 18Third term : a₃ = 2(a₂ + 4) = 2(18 + 4) = 2(22) = 44
Fourth term : a₄ = 2(a₃ + 4) = 2(44 + 4) = 2(48) = 96
Fifth term : a₅ = 2(a₄ + 4) = 2(96 + 4) = 2(100) = 200
Hence, the first 5 terms of the sequence are :

How to determine the rule?From the table, we can see that:
The output of the table is 1 more than 3 times the input
If the input is x, then the output y is:
y = 1 +3 * x
Evaluate
y = 1 + 3x
Hence, the rule for the input/output table is f(x) = 1 + 3x
