Answer:
[tex]log_372 = 3.8928[/tex]
Step-by-step explanation:
Given
[tex]log_38 = 1.8928[/tex]
Required
Evaluate [tex]log_372[/tex]
We have:
[tex]log_372 = log_3(8 *9)[/tex]
Apply law of logarithm
[tex]log_372 = log_38 +log_39[/tex]
Express 9 as 3^2
[tex]log_372 = log_38 +log_33^2[/tex]
Evaluate the exponents
[tex]log_372 = log_38 +2log_33[/tex]
[tex]log_33 = 1[/tex].
So:
[tex]log_372 = log_38 + 2 * 1[/tex]
[tex]log_372 = log_38 + 2[/tex]
Substitute [tex]log_38 = 1.8928[/tex]
[tex]log_372 = 1.8928 + 2[/tex]
[tex]log_372 = 3.8928[/tex]

Can the table below represent values of a function? explain why.
Try it yourself, I'll explain the concept
In a function, each x-value matches to exactly one y-value
If it matches to more than one y-value, it is not considered a function
Now look at the x and y values in each table to determine if it is a function or not

The length of a rectangle is 20 inches less than twice the width. The perimeter of the rectangle is 86 inches. Find the dimensions of the rectangle.
Answer:
length=22
width=21
Step-by-step explanation:
let, length be x and width be y.
x=2y-20
2(x+y)=86
or, 2(2y-20+y)=86
or, 2(3y-20)=86
or, 6y-40=86
or, 6y= 126
or, y= 126/6
y= 21
x= 2×21-20 = 42-20 =22
What is the approximate area of the circle shown below?
Answer:
A
Step-by-step explanation:
A
9x - 40
B
3x + 20
x = [?]
Answer:
x = 10
Step-by-step explanation:
9x - 40 = 3x + 20
9x - 3x - 40 = 3x - 3x + 20
6x - 40 = 20
6x - 40 + 40 = 20 + 40
6x = 60
6x / 6 = 60 / 6
x = 10
Now plug the x value in the equation to make the statement true that A is parallel to B.
9x - 40
9(10) - 40
90 - 40
50
3x + 20
3(10) + 20
30 + 20
50
Therefore, x = 10 making the statement true that A is parallel to B. Hope this helps and stay safe, happy, and healthy, thank you :) !!
Answer: 10
Step-by-step explanation:
Which equations are equivalent to 33/x+ 4 = 12? Check all that apply.
3x + 4 = 9
43 = 3x + 4
O x + 4 = 64
U 3+ 4 = - 4
0 60 = x
Answer:
option c
x + 4 = 64
and
option e
x = 60
Step-by-step explanation:
Given in the question an expression
3∛x+4 = 12
∛x + 4 = 12/3
∛x + 4 = 4
Take cube on both sides of the equation
∛(x + 4)³ = 4³
x + 4 = 64
x = 64 - 4
x = 60
Josie does 9 minutes
of stretches before she runs. She runs for
20 minutes. Then she does 7 minutes of cool
down exercises. The clock shows the end time 3:45 of
her workout. At what time does Josie start her
workout? Describe how you found the time.
Answer: Josie starts working out at 3:09
Step-by-step explanation: I found this answer by adding the workout time together.
Answer:
3:09
Step-by-step explanation:
First add the total time of the workout
20+9+7=36
then subtract the end time 3:45 with the workout time:
3:45-00:36=3:09
Check work:
3:09+00:36=3:45

PLEASE HELP !! ILL GIVE BRAINLIEST *EXTRA 40 POINTS* DONT SKIP :(( .!
Answer: The answer is ONE Solution
Step-by-step explanation:
A system of equations have no solution when their slopes are the same but they have different y-intercepts. When graphed, the lines cannot intersect for there to be a solution. Looking at both equations, they have different slopes and different y intercepts so you can rule "NO solution" out.
Secondly a system of equations have infinitely many solution if they both share the same slopes and y-intercepts.
Looking at both lines, they have different slopes and different y-intercepts, so you can also rule that out.
A system of equations have one solution if their slopes are different and y intercepts are also different. Looking at the two lines, we can notice that the slope and y-intercepts are all different.

Answer:
133
Step-by-step explanation:
180 - 47 = 133
Answer:
133°
Step-by-step explanation:
If we assume the the given to adjacent lines to be parallel then ,
The x and supplement of 47° will be equal since they will be corresponding angles .Therefore :-
=> x = 180° - 47°
=> x = 133° .
Hence the size of angle X is 133°Which table shows a linear relationship

Answer:
[tex]2\frac{2}{5}=\frac{12}{5}[/tex]
[tex]3\frac{1}{6}=\frac{19}{6}[/tex]
Step-by-step explanation:
In [tex]2\frac{2}{5}[/tex] you multiply 2x5 which equals 10 and then you add 10+2=12
2x5=10
10+2=12
=[tex]\frac{12}{5}[/tex]
You do the same thing multiply the denominator by the whole number and whatever you get when you multiply add it with the numerator.
3x6=18
18+1=19
=[tex]\frac{19}{6}[/tex]

Consider this absolute value function.

If function f is written as a piecewise function, which piece will it include?
A. x + 3, x > 3
B. x + 3, x > -3
C. -x + 3, x < -3
D. -x - 3, x < 3
Answer:
B) x + 3, x > -3
Step-by-step explanation:
I just took a test with this question on it and got it right.
Hope this helps! :)
If function f is written as a piecewise function, it will include x + 3, x > -3
The absolute value function is given as:
f(x) = | x + 3 |
Given that the function is an absolute value function, this means that:
|x + 3| > 0
Remove the absolute sign
x + 3 > 0
Subtract 3 from both sides
x > -3
Hence, if function f is written as a piecewise function, it will include x + 3, x > -3

Given a long algebraic expression, what are some strategies that you can use to make simplifying and evaluating the expression more efficient and accurate?
How do inverse operations help solve algebraic equations? Give a real-world scenario where this might be modeled.
Answer:
See below.
Step-by-step explanation:
To simplify a long algebraic expression, you could use many methods. My personal choice is to use distribution in order to follow PEMDAS and eliminate any parenthesis within my equation. I also like to combine like terms to shorten the equation as much as possible.
Inverse operations are extremely helpful in isolating variables and simplifying equations. They can be used in many scenarios from finding the length of an object with only a formula and one side (ex. a triangle with only b and A given) to having distance and speed to figure out the time it will take to get to your destination.
Identify the graph which shows the figure in graph A, rotated 90° in a clockwise direction around the origin.

In a law office, the average number of billed hours per day was 150 last year. In the first 85 days of this year, the average number of billed hours per day is 158 with a standard deviation of 65 hours. When testing the hypothesis (at the 10% level of signficance) that the average number of billed hours per day has increased, what is the null and alternative hypotheses (please write out the null and alternative hypotheses below AND on your scratch work...failure to do BOTH will result in 0 points)
Answer:
There isn't enough evidence to reject H0
Step-by-step explanation:
Null hypothesis :
H0: μ = 150
H1 : μ > 150
Decision region :
Reject Null if ;
Pvalue < α
Zstatistic = (x - μ) / (s/sqrt(n))
Zstatistic = (158 - 150) / (65/sqrt(85))
Zstatistic = 0.1135
Using the P value calculator from Zstatistic at 90% ; α = 0.10 confidence interval ; one tailed test = 0.128
Pvalue = 0.128
Since ; 0.128 > 0.10
Pvalue > α
We cannot reject H0:
Use slope-intercept form to write an equation of a line passing through the given point and having the given slope. Express the answer in standard form.
P(−4, −6); m = −3/4
9514 1404 393
Answer:
3x +4y = -36
Step-by-step explanation:
The slope-intercept form is ...
y = mx + b
where m is the slope and b is the y-intercept. From this equation, we can find the y-intercept as ...
b = y -mx
For the given point and slope, this is ...
b = -6 -(-3/4)(-4) = -9
Then the slope-intercept equation is ...
y = -3/4x -9
We can multiply by 4 to get something we can put in standard form.
4y = -3x -36
3x +4y = -36 . . . . standard form equation
