Step-by-step explanation:
To compute a log that doesn't have a base of 10 you use the following formula
Log(number)/Log(base)
We can use this formula to compute the numbers with no variables
Log₃18= Log(18)/log(3) which gives us around 2.63
We can then compute the first part of the right side 2*log₃6 which can be rewritten as 2*(log(6)/log(3)) which gets us around 3.26
After computing this we can rewrite it all as 2.63=3.26-(.5*log₃x)
This is pretty easy to solve from here and we start by subtracting 3.26 from both sides which gives up
-.63=.5*log₃x
Dividing both sides by negative one half (or .5) gives us
1.26=log₃x
You then can use a special rule to rewrite this equation
3^1.26=x
This gives us 3.99 which is pretty much 4

e total cost of Anja's trip to the dentist was $628.35. She paid a flat fee of $89.95 which included the checkup an
aning and then had 4 cavities filled, each of which cost the same amount. Which shows the correct equation and
ue of x, the cost of each cavity filling?
4x+89.95=628.35; X = $134.60
4(89.95) + X = 628.35
X = $268.55

Answer:
(a) 4x+89.95=628.35; x = $134.60
Step-by-step explanation:
The total cost (628.35) is the cost per cavity (x) times the number of cavities (4), added to the flat fee (89.95). The equation for that is ...
4x +89.95 = 628.35
The solution to that is ...
x = (628.35 -89.95)/4 . . . . . subtract the constant, divide by 4
x = 134.60

Help pls I don’t remember how to do this so how do u find x, y, and z in this
Answers
Answer: 3) x = 87°; y = 93°; z = 63°
Step-by-step explanation:
x + 33 + 60 = 180 since they form a triangle.
x + 93 = 180
Subtract 93 from both sides
x = 87°
x and y are linear pairs so they're supplementary.
y + x = 180
y + 87 = 180
Subtract 87 from both sides
y = 93°
z + y + 24 = 180 since they also form a triangle
z + 93 + 24 = 180
z + 117 = 180
Subtract 117 from both sides
z = 63°

Set A of six numbers has a standard deviation of 3 and set B of four numbers has a standard deviation of 5. Both sets of numbers have an equal mean. If the two sets of numbers are combined, find the variance.
Answers
Given:
[tex]\sigma_A=3[/tex]
[tex]n_A=6[/tex]
[tex]\sigma_B=5[/tex]
[tex]n_B=4[/tex]
[tex]\overline{x}_A=\overline{x}_B[/tex]
To find:
The variance. of combined set.
Solution:
Formula for variance is
[tex]\sigma^2=\dfrac{\sum (x_i-\overline{x})^2}{n}[/tex] ...(i)
Using (i), we get
[tex]\sigma_A^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{n_A}[/tex]
[tex](3)^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}[/tex]
[tex]9=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}[/tex]
[tex]54=\sum (x_i-\overline{x}_A)^2[/tex]
Similarly,
[tex]\sigma_B^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{n_B}[/tex]
[tex](5)^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}[/tex]
[tex]25=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}[/tex]
[tex]100=\sum (x_i-\overline{x}_B)^2[/tex]
Now, after combining both sets, we get
[tex]\sigma^2=\dfrac{\sum (x_i-\overline{x}_A)^2+\sum (x_i-\overline{x}_B)^2}{n_A+n_B}[/tex]
[tex]\sigma^2=\dfrac{54+100}{6+4}[/tex]
[tex]\sigma^2=\dfrac{154}{10}[/tex]
[tex]\sigma^2=15.4[/tex]
Therefore, the variance of combined set is 15.4.

Answer:
A, y-intercept = (0,24)
Step-by-step explanation:
The y intercept is the one without a variable. You have to solve to find it in the other options.
Answer:
The first choice would be the best one.
Step-by-step explanation:
The y intercept occurs when x = 0 of the given polynomial.
All 3 answers will give you the correct answer. The y intercept is (0,24)
but the first one will be the quickest because all you need to do to find it is just eliminate any term with x in it.
2x^2 when x = 0 is 0
16x when x = 0 is 0.
That only leaves m(0) = 24 found just by looking at it.
The second one also works. 2 (0+4)^2 - 8 = 32 - 8 = 24
And the third one as well 2(6)(2) = 24

If 6 days ago was Wednesday, what day will it be 701 days from now?
A Wednesday
B Thursday
C Friday
D Saturday
E Sunday
show work!!
Answers
Answer:
Friday
Step-by-step explanation:
If 6 days ago was Wednesday, that means 6 days ago was Thursday. Every seven days, it will be Thursday again, so we can do 701/7 and see how many weeks fit equally. It is 100 weeks and 1 day. That means that Thursday would be in 100 weeks, or 700 days. Since there is one day left, it would be Friday. Friday is your answer.
The day after 701 days from today if, 6 days ago was Wednesday is Friday, so option C is correct.
What is division?One of the fundamental mathematical operations is division, which involves breaking a bigger number into smaller groups with the same number of components.
Given:
If 6 days ago was Wednesday,
If 6 days ago was Wednesday, then it will be Thursday today,
Calculate the day after 701 days as shown below,
The day = 701 / total days
As you can see, the Thursday will be repeated after 7 days,
Here, 1 will be the reminder, then one day after Thursday will be Friday.
Thus, after 701 days, it will be Friday.
