Using the Fundamental Counting Theorem, it is found that he has 10 possible options to choose from.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem:
For the semester, he has 2 possible options, hence [tex]n_1 = 2[/tex].For the country, he has 5 possible options, hence [tex]n_2 = 5[/tex].The total number of options is given by:
N = 2 x 5 = 10.

Consider f(x) = bx. which statement(s) are true for 0 < b < 1? check all that apply. the domain is all real numbers. the domain is x > 0. the range is all real numbers. the range is y > 0. the graph has x-intercept 1. the graph has a y-intercept of 1. the function is always increasing. the function is always decreasing.
The true statement for f(x)=b^x is the function is always decreasing function.
We have given,
f(x)=b^x where 0<b<1
What is the domain?Domain is all possible values of x for which any function is defined
We can select any values of x for which function
It will be defined for all real x
So, the domain is [tex](-\infty,\infty)[/tex]
The range is all possible values of y for which x is defined
we are given that b is positive
The value of the function will always be positive
So, the range is [tex](0,\infty)[/tex]
y>0
The x-intercept:
Set f(x)=0 and then we can solve for x
f(x)=b^x=0
x is undefined
The x-intercept does not exist
Increasing or decreasing:
Since, 0<b<1
The b is a positive value less than 1
As we increase the value of, [tex]b^x[/tex] will keep decreasing
This is decreasing function

Use the function f(x) = x2 – 2x + 8 and the graph of g(x) to determine the difference between the maximum value of g(x) and the minimum value of f(
2.
Answer:
3 or 4, I am confused
Step-by-step explanation:
I'll assume that f(x) = x2 – 2x + 8 is meant to be f(x) = x^2 – 2x + 8
Find the value of f(x) for x = 2:
f(x) = x^2 – 2x + 8
f(2) = (2)^2 – 2*(2) + 8
f(2) = 4 - 4 + 8
f(2) = 8
=============
From the graph, we can find that g(2) = 11
The differece between g(2) and f(2) is thus:
11 - 8 = 3
3 is not an option, so I wonder if the question is asking for the difference between the absolute maximum of g(x) and f(2). If so, the maximum for g(x) is 12, at x = 3.
This would lead to a difference of 12 - 8, or 4. This is still not an option, so I'm confused. Perhaps you can find my error and find the ciorrect answer, or at least one that appears in the options.

C. {x | x=2}
D. {x | x=-2,4}

Answer:
{x | x ≠ -1, 2, 4}
Step-by-step explanation:
Domain: input values (x-values)
Asymptote: a line which the curve gets infinitely close to, but never touches.
Hole: a point on the graph where the function is not defined.
From inspection of the graph:
Vertical asymptotes at x = -1 and x = 4Hole at x = 2As vertical asymptotes and holes restrict the domain of a rational function, the domain is {x | x ≠ -1, 2, 4}

if angle 6 is 25 degrees how much is 7
Given:
Angle 6 = 25 degrees
To Find:
The value of Angle 7
Solution:
We know that,
the value of Angle 6 is equal to 25 Degrees
Since Angle 6 and Angle 7 together comprise of a Straight Line, this means that they are Supplementary Angles.
Therefore,
Angle 6 + Angle 7 = 180 degrees
This implies that,
25 degrees + Angle 7 = 180 degrees. (since Angle 6 = 25 Degrees)
Angle 7 = (180-25) degrees
Thus ,
Angle 7 = 155 degrees
Hence, Angle 7 is 155 degrees (Option 1)

A student usually saves $20 a month. He would like to reach a goal of saving $350 in 12 months. The student writes the equation 350 = 12(x+20) to represent this situation. Solve the equation for x.
Write your answer as a sentence that describes what the variable x represents.
Enter your answers and your work or explanation in the box provided.
Answer:
The student would need to save $9.17 more per month
Step-by-step explanation:
350 = 12(x+20)
350 = 12x + 240
12x = 110
x = 110/12
x = $9.17

Let's start the sum as follows:
x³ = 8
X × X × X = 8
This means there are 3 number which after Multiplication gives answer 8.
If 2 is multtiplied 3 times it will give you 8
Thus the answer of x is 2
x = 2.
x^3 = -8
The cube root of 8 is 2 = 2 x 2 x 2 is 8.
But, the answer is negative, which means that the cube root of -8 must be -2.

By how much would the mode increase if the number 80 were added to the set?
Answer:
The mode would not increase or decrease.
Step-by-step explanation:
I say this because the mode is the value(s) in the data set that occur most frequently. 30 is the mode before adding 80 because 30 is in the set 3 times, more than the other values. Because 80 would be the only 80 in the set it would not become the mode once added. I hope this explained my reasoning and helped!
