You can simplify 2log base2 (x) by moving the 2 inside the logarithm.
Log base 2 (6-x) = log2 (x^2)
For the equation to be equal the argument of the logarithm on both sides of the equation must also be equal.
6-x = x^2
Solve for X.
X = 2, -3

Question 19:
Answer: C. 1.25 miles
So far, [tex]\frac{1}{10}[/tex] of the 12.5 miles is 1.25 miles. Let's see why!
Very simple all we need to is divide by 10 because our fraction is [tex]\frac{1}{10}[/tex]. So our equation is going to look something like this:
12.5 ÷ 10 = 1.25
Therefore, our answer is, C. 1.25 miles.
Phew! I don't think I would want to run 1.25 miles let alone 12.5! That's what I call dedication!
Question 20:
Answer: A. 8 bags
For this question all we need to do is divide 6.24 by 0.78 pounds of trail mix. This is to see how many bags Leon had purchased.
6.24 ÷ 0.78 = 8
Therefore our answer is 8 bags.
TIPS!!!
If you ever have questions like 19 always look for what the denominator is and divide by that.
If you ever have a question like 20 divide by the total amount of product purchased and than how much that cost was for whatever measurement it may be. (or weight)

Mariah is studying the life cycle of the monarch butterfly. She must choose one stage in the cycle to present in science class: egg, caterpillar, chrysalis, or adult. She plans to make her choice randomly using a custom spinner divided into four sections. First, however, she spins the spinner 50 times to see the frequencies it generates.
Stage Times Landed On
egg 10
caterpillar 12
chrysalis 15
adult 13
The relative frequency of landing on egg is .
The relative frequency of landing on caterpillar is .
The relative frequency of landing on chrysalis is .
The relative frequency of landing on adult is .
All the outcomes be considered equally likely.
Answers
The relative frequency of landing on an egg, caterpillar, chrysalis and adults are 0.2, 0.24, 0.3 and 0.26.
What is the relative frequency?"Relative frequency represents the ratio of the number of times a value of the data occurs in a dataset".
For the given situation,
Number of times egg landed on spin, x1 = 10
Number of times caterpillar landed on spin, x2 = 10
Number of times chrysalis landed on spin, x3 = 15
Number of times adult landed on spin, x4 = 13
Total number of times, n = 50
The formula for relative frequency = [tex]\frac{x}{n}[/tex]
The relative frequency of landing on an egg = [tex]\frac{10}{50}[/tex]
⇒ [tex]0.2[/tex]
The relative frequency of landing on caterpillar = [tex]\frac{12}{50}[/tex]
⇒[tex]0.24[/tex]
The relative frequency of landing on chrysalis = [tex]\frac{15}{50}[/tex]
⇒ [tex]0.3[/tex]
The relative frequency of landing on adults = [tex]\frac{13}{50}[/tex]
⇒ [tex]0.26[/tex]
Hence we can conclude that the relative frequency of landing on an egg, caterpillar, chrysalis, and adults are 0.2, 0.24, 0.3 and 0.26.

One the first day of school, each student is given $0.50 to attend. On day two, each student earns $1.00, day 3, $2.00, etc. How much do students earn on the ninth day of school?
Answers
Answer:
They earn $256 on the ninth day of school.
Step-by-step explanation:
A geometric sequence(in which each term is the previous term multiplied by the ratio) has the following format:
[tex]a_{n+1} = r \times a_{n}[/tex]
In which r is the common ratio.
We can also find the nth term as a function of the first term, by the following equation:
[tex]a_{n} = a_{1} \times r^{n}[/tex]
In which
[tex]r = \frac{a_{n+1}}{a_{n}}[/tex]
In this question:
On the first day, $0.50. So [tex]a_{1} = 0.5[/tex].
Day two $1.00, day three $2.00.
So
[tex]r = \frac{1}{0.5} = \frac{2}{1} = 2[/tex]
Then
[tex]a_{n} = 0.5 \times 2^{n}[/tex]
How much do students earn on the ninth day of school?
[tex]a_{9} = 0.5 \times 2^{9} = 256[/tex]
They earn $256 on the ninth day of school.

Answer:
[tex]f(x)=-5x-3[/tex].
Step-by-step explanation:
From the given machine diagram it is clear that:
[tex]f(x)=-8[/tex] at [tex]x=1[/tex]
[tex]f(x)=-13[/tex] at [tex]x=2[/tex]
[tex]f(x)=-18[/tex] at [tex]x=3[/tex]
It is clear that the value of f(x) decreasing by 5 when the value of x is increasing by 1.
Since the function changing at a constant rate, therefore it represents a linear function.
If a linear function passing through two points, then the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The given linear function passes through (1,-8) and (2,-13), therefore the linear equation is
[tex]y-(-8)=\dfrac{-13-(-8)}{2-1}(x-1)[/tex]
[tex]y+8=\dfrac{-5}{1}(x-1)[/tex]
[tex]y+8=-5(x-1)[/tex]
[tex]y=-5x+5-8[/tex]
[tex]y=-5x-3[/tex]
So, the required function is [tex]f(x)=-5x-3[/tex].

Explain. A. True, because the list of variables (x 1 comma ... comma x Subscript n Baseline )and the list of numbers (s 1 comma ... comma s Subscript n Baseline )have a one-to-one correspondence. B. False, because the description applies to a single solution. The solution set consists of all possible solutions.
Answers
Answer:
B. False, because the description applies to a single solution. The solution set consists of all possible solutions.
Step-by-step explanation:
The choice of true or false revolves around whether a linear system can have more than one solution.
The problem statement does not say the equations are independent, a condition that must be satisfied if there is to be only one solution. Hence we must assume that the system may be dependent or even inconsistent, leading to zero, one, or an infinite number of solutions. The answer above carries its own explanation.
False, for the reason given
Which equation represents an exponential function with an initial value of 500?
Answers
Answer:
An exponential function is written in the form of f(x) = a (b)x. When we want to find an initial value of 500, it means that when x = 0, then y must equal 500. So, you plug in 0 to x in the exponential function, which leaves you with f(0) = a. Then, since f(0) = 500, that means a = 500

Find the circumference of the circle and subtract the length of the minor arc
Circumference of circle = 2 * pi * r = 2 * pi * 15 = 30 pi
length of arc = angle/360 * 2 * pi * r = 23/360 * 2 * pi * 15 = 1.92 pi
subtraction will give 30 pi - 1.92 pi = 28.08 pi

lan ran 24 laps in a charity run and then walked 0.2 kilometer to the presentation table the total; distance lan traveled was 29.6 kilometer what was the distance of each lap explain how you solve the problem
Answers
Answer:
Step-by-step explanation:
1.225km is equal to each laps
Step-by-step explanation:
Since Kristy total distance traveled = 29.6km
And Kristy ran 24 laps and later walk 0.2km. it simply implies that
Total distance traveled = distance covered running + distance covered walking
Since we know that
Total distance traveled = 29.6km
distance covered running = 24 laps
distance covered walking = 0.2km
Distance covered running in km = total distance traveled - distance covered walking
Distance covered running in km = 29.6km - 0.2km = 29.4km.
To now find the distance for each lap.
Since we have:
Distance covered running in km = 29.4km.
Distance covered running in lap = 24 laps
i.e
24 laps = 29.4km
1 lap = x
Use cross-multiple
24 laps * x = 29.4km × 1 lap
x = 29.4km / 24
x = 1.225km
Therefore
1.225km is equal to each laps.
Answer:1.225km is equal to each laps

Thus, the determinant of an elementary scaling matrix with k on the diagonal is nothing.
Answers
Answer:
exactly one, 0's, triangular matrix, product and 1.
Step-by-step explanation:
So, let us first fill in the gap in the question below. Note that the capitalized words are the words to be filled in the gap and the ones in brackets too.
"An elementary ntimesn scaling matrix with k on the diagonal is the same as the ntimesn identity matrix with EXACTLY ONE of the (0's) replaced with some number k. This means it is TRIANGULAR MATRIX, and so its determinant is the PRODUCT of its diagonal entries. Thus, the determinant of an elementary scaling matrix with k on the diagonal is (1).
Here, one of the zeros in the identity matrix will surely be replaced by one. That is to say, the determinants = 1 × 1 × 1 => 1. Thus, it is a a triangular matrix.
