c for the question that says what point is on [tex]y=\log_a(x)[/tex] given the options.
9 for the question that reads: "If [tex]\log_a(9)=4[/tex], what is the value of [tex]a^4[/tex].
Step-by-step explanation:
We are given [tex]y=\log_a(x)[/tex].
There are some domain restrictions:
[tex]a \text {is number between } 0 \text{ and } 1 \text{ or greater than } 1[/tex]
[tex]x \ge 0[/tex]
a) couldn't be it because x=0 in the ordered pair.
b) isn't is either for the same reason.
c) \log_a(1)=0 \text{ because } a^0=1[/tex]
So c is so far it! Since (x,y)=(1,0) gives us [tex]0=\log_a(1)[/tex] where the equivalent exponential form is as I mentioned it two lines ago.
d) Let's plug in the point and see: (x,y)=(a,0) implies [tex]0=\log_a(a)[/tex].
The equivalent exponetial form is [tex]a^0=a[/tex] which is not true because [tex]a^0=1 (\neq a)[/tex].
If [tex]\log_a(9)=4[/tex]. then it's equivalent exponential form is: [tex]a^4=9[/tex].
Guess what it asked for the value of [tex]a^4[/tex] and we already found that by writing your equation [tex]\log_a(9)=4[/tex] in exponential form.
Note:
The equivalent exponential form of [tex]\log_a(x)=y[/tex] implies [tex]a^y=x[/tex].

A bag contains 12 red marbles, 5 yellow marbles, and 15 green marbles. How many additional red marbles must be added to the 32 marbles already in the bag so that the probability of randomly drawing a red marble is ?
Answers
Answer:
18 red marbles.
Step-by-step explanation:
The complete question asks the probability of randomly drawing a red marble is 3/5?
Let x be the number of red marbles that must be added.
To find x we will do the following:
[tex]\frac{x+12}{x+32} =\frac{3}{5}[/tex]
=>[tex]5(x+12)=3(x+32)[/tex]
=> [tex]5x+60=3x+96[/tex]

A widget company produces 25 widgets a day,5 of which are defective.Find the probability of selecting 5 widgets from the 25 produced where none are defective
Answers
Answer:
1/5
Step-by-step explanation:
The probability of selecting 5 widgets from the 25 produced where none are defective is 0.2914.
To calculate the probability of selecting 5 non-defective widgets from the 25 produced.
The number of ways to choose 5 non-defective widgets:
[tex]\[ \binom{20}{5} = \frac{20!}{5!(20-5)!} \][/tex]
[tex]\[ = \frac{20 \times 19 \times 18 \times 17 \times 16}{5 \times 4 \times 3 \times 2 \times 1} \][/tex]
[tex]\[ = \frac{20 \times 19 \times 18 \times 17 \times 16}{5 \times 4 \times 3 \times 2 \times 1} \][/tex]
[tex]\[ = \frac{1860480}{120} \][/tex]
= 15504
The total number of ways to choose 5 widgets from the 25 produced:
[tex]\[ \binom{25}{5} = \frac{25!}{5!(25-5)!} \][/tex]
[tex]\[ = \frac{25 \times 24 \times 23 \times 22 \times 21}{5 \times 4 \times 3 \times 2 \times 1} \][/tex]
[tex]\[ = \frac{7893600}{120} \][/tex]
= 53130
The probability:
Probability = (Number of ways to choose 5 non-defective widgets)/(Total number of ways to choose 5 widgets)
[tex]\[ = \frac{15504}{53130} \][/tex]
[tex]\[ = 0.2914 \][/tex]

The variable z is directly proportional to x, and inversely proportional to y. When x is 4 and y is 10, z has the value 0.8. What is the value of z when x= 13, and y= 18
Answers
Answer:
13/9
Step-by-step explanation:
Directly proportional means it will be multiply to our constant k.
Inversely proportional means it will divide our k.
So we are given z is directly proportional to x and inversely proportional to y.
This means:
[tex]z=k \cdot \frac{x}{y}[/tex].
We are given (x=4,y=10,z=0.8). We can use this to find k. The k we will find using the point will work for any point (x,y,z) since k is a constant. A constant means it is to remain the same no matter what.
[tex]0.8=k \cdot \frac{4}{10}[/tex]
[tex]0.8=k(.4)[/tex]
Divide both sides by .4:
[tex]\frac{0.8}{0.4}=k[/tex]
[tex]k=2[/tex]
The equation for any point (x,y,z) is therefore:
[tex]z=2 \cdot \frac{x}{y}[/tex].
We want to find z given x=13 and y=18.
[tex]z=2 \cdot \frac{13}{18}[/tex]
[tex]z=\frac{2 \cdot 13}{18}[/tex]
[tex]z=\frac{13}{9}[/tex]

Answers
Answer:
y=2.5x+7
Step-by-step explanation:
You are basically being asked to use slope-intercept form for linear equations. It says y=mx+b where m is the slope and b is the y-intercept.
Plug in 2.5 for m and 7 for b giving you y=2.5x+7.
The equation is: y = mx + b
y = 2.5x + 7
so it's option D.
Suppose that the length of a certain rectangle is four centimeters more than three times its width. If the area of the rectangle is 95 square centimeters, find its length and width.
Answers
Answer: The length and width of the rectangle are 19 cm and 5 cm respectively.
Step-by-step explanation: Given hat the length of a rectangle is four centimeters more than three times its width and the area of the rectangle is 95 square centimeters.
We are to find the length and width of the rectangle.
Let W and L denote the width and the length respectively of the given rectangle.
Then, according to the given information, we have
[tex]L=3W+4~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
Since the area of a rectangle is the product of its length and width, so we must have
[tex]A=L\times W\\\\\Rightarrow 95=(3W+4)W\\\\\Rightarrow 3W^2+4W-95=0\\\\\Rightarrow 3W^2+19W-15W-95=0\\\\\Rightarrow W(3W+19)-5(3W+19)=0\\\\\Rightarrow (W-5)(3W+19)=0\\\\\Rightarrow W-5=0,~~~~~3W+19=0\\\\\Rightarrow W=5,~-\dfrac{19}{3}.[/tex]
Since the width of the rectangle cannot be negative, so we get
[tex]W=5~\textup{cm}.[/tex]
From equation (i), we get
[tex]L=3\times5+4=15+4=19~\textup{cm}.[/tex]
Thus, the length and width of the rectangle are 19 cm and 5 cm respectively.
The length of the rectangle is 19 and the width is 5 and it can be determined by using the formula of area of the rectangle.
Given that,The length of a certain rectangle is four centimeters more than three times its width.
If the area of the rectangle is 95 square centimeters,
We have to determine,The length and width of the rectangle.
According to the question,Let the length of the rectangle be L,
And the width of the rectangle is W.
The length of a certain rectangle is four centimeters more than three times its width.
The perimeter of a square is the sum of the length of all its four sides.The perimeter formulas of different two-dimensional shapes:
Then,
[tex]\rm L = 3W+4[/tex]
And If the area of the rectangle is 95 square centimeters,
The area of any polygon is the amount of space it occupies or encloses.It is the number of square units inside the polygon.
The area is a two-dimensional property, which means it contains both length and width
[tex]\rm Area \ of \ the \ rectangle = length \times width\\\\L\times W = 95[/tex]
Substitute the value of L from equation 1,
[tex]\rm L\times W = 95\\\\(3W+4) \times W = 95\\\\3W^2+4W=95\\\\3W^2+4W-95=0\\\\3W^2+19W-15W-95=0\\\\W(3W+19) -5(3W+19) =0\\\\(3W+19) (W-5) =0\\\\W-5=0, \ W=5\\\\3W+19=0, \ W = \dfrac{-19}{3}[/tex]
The width of the rectangle can not be negative than W = 5.
Therefore,
The length of the rectangle is,
[tex]\rm L = 3W+4\\\\L = 3(5)+4\\\\L=15+4\\\\L=19[/tex]
Hence, The length of the rectangle is 19 and the width is 5.

A country has 50 million people, 30 million of whom are adults. Of the adults, 5 million are not interested in working, another 5 million are interested in working but have given up looking for work, and 5 million are still looking for work. Of those who do have jobs, 5 million are working part time but would like to work full time, and the remaining 10 million are working full time. What is this country's labor force participation rate?
Answers
Answer:
66.7% is the answer.
Step-by-step explanation:
A country has 50 million people, 30 million of whom are adults.
Of the adults, 5 million are not interested in working.
5 million are interested in working but have given up looking for work.
5 million are still looking for work.
Of those who do have jobs, 5 million are working part time but would like to work full time, and the remaining 10 million are working full time.
Total labor force = Employed people + Unemployed people
=> 15 million+ 5 million = 20 million
The labor force participation rate is [tex]\frac{20million}{30million} \times100[/tex]
= 66.66% ≈ 66.7%.
The labor force participation rate of the country is 66.7%, calculated by dividing the number of employed and actively seeking employment individuals (20 million) by the total adult population (30 million) and multiplying by 100.
To calculate the labor force participation rate, we include only those adults who are either employed or actively seeking employment. In the given scenario, the country has 30 million adults. Out of these, 5 million are not interested in working, 5 million have given up looking for work, and there are 15 million employed (10 million full-time and 5 million part-time). Therefore, the labor force includes those employed full-time, employed part-time, and those actively looking for work, adding up to 20 million.
The labor force participation rate is calculated by dividing the number of people in the labor force (20 million) by the total adult population (30 million) and multiplying the result by 100 to convert it into a percentage:
Labor Force Participation Rate = (Number in labor force ÷ Total adult population) x 100
Labor Force Participation Rate = (20 million ÷ 30 million) x 100
Labor Force Participation Rate = (2÷3) x 100
Labor Force Participation Rate = 66.7%

So, the correct option is, D. 3
Why?We need to remember that if two or more lines are parallel, they will share the same slope, no matter where are located their x-intercepts and y-intercepts, the only condition needed for them to be parallel, is to have the same slope.
So, if two lines are parallel, and one of them (the red line) has a slope of 3, the slope of the other line (the green line) will also be 3.

33π square units
Step-by-step explanation:
The area of a sector is given by this formula. The larger sector angle is 2π-π/6 = 11π/6 radians.
A = (1/2)r²θ = (1/2)6²(11π/6) = 33π . . . . square units
Answer:
Area of larger sector = 33π units²
Step-by-step explanation:
Points to remember
Area of circle = πr²
Where 'r' is the radius of circle
To find the area of circle
Here r = 6 units
Area = πr²
= π * 6²
= 36π units²
To find area of large sector
The central angle of larger sector = 360 - 30 = 330
Area of larger circle = (330/360) * area of circle
= (330/360) * 36π
= 33π units²

Answers
Answer:
beginning inventory is $245000
Step-by-step explanation:
Given data
ending inventory = $150,000
purchased additional inventory = $375,000
goods sold = $470,000
to find out
beginning inventory
solution
according to question beginning inventory is calculated by this formula i.e.
beginning inventory = ( cost of goods sold + ending inventory ) - amount of inventory purchase .....................1
now put all value cost of goods sold, ending inventory and amount of inventory purchase in equation 1 and we get beginning inventory
beginning inventory = ( cost of goods sold + ending inventory ) - amount of inventory purchase
beginning inventory = ( 470000 + 150000 ) - 375000
beginning inventory = 245000
so beginning inventory is $245000

That means that the road is still missing 3/8 of a mile til it's finished. The length of the road is found by adding the 3/4 to the 3/8:
[tex]\frac{3}{4}+\frac{3}{8}=\frac{6}{8}+\frac{3}{8}=\frac{9}{8}[/tex]
So the road is a total of 1 1/8 miles long.
For b. we need to find out how much of 1 1/8 is 1 mile:
1 mile = x * 9/8 and
x = 8/9. When 1 mile of the road is completed, that is 8/9 of the total length of the road completed.
draw a diagram for this statement
eight percent of the 320 students like sports
use your diagram to determine the number of students who do not like sports
Answers
80% of 320 is 256
Therefore 20% is 64
Approximately 26 out of 320 students like sports. Therefore, about 294 students do not like sports.
Explanation:To draw a diagram for the given statement, we begin with understanding that the total of 320 students represents 100%. Therefore, if 8% of the students like sports, we would multiply 320 by 0.08 (or 8%).
The calculation would be:
320 * 0.08 = 25.6
However, because we cannot have a fractional student, we round this figure to 26. This implies that about 26 students like sports.
To calculate the number of students who do not like sports, subtract the number that do from the total, which is 320. That calculation would be:
320 - 26 = 294
Therefore, approximately 294 students do not like sports.
