Answer:
y = 7*(2)^x
Step-by-step explanation:
We know that we have a function of the form:
y = a*b^x
Such that a and b are real numbers, and b also needs to be a positive number.
Such that this function passes through the points (3, 56) and (5, 224)
This means that:
56 = a*b^3
224 = a*b^5
So we have a system of two equations with two variables.
To solve this, we can take the quotient of the two equations (such that the second one is on the numerator) then we get:
(224/56) = (a*b^5)/(a*b^3)
4 = (a/a)*(b^5/b^3) = b^(5 - 3) = b^2
4 = b^2
Then we get:
√4 = b = 2
(because b needs to be positive we only care for the positive square root of 4)
The equation is something like:
y = a*(2)^x
Now we can use again the point (3, 56), so:
56 = a*(2)^3 = a*8
56 = a*8
56/8 = a = 7
Then the exponential equation is:
y = 7*(2)^x

What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b
or [tex]\dfrac{a}{b}[/tex]
We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).
Suppose that we've got a = 6, and b= 4, then:
[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]
Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.
Given;
The ration in directions=3:4
Here, jade has added 12 quarts of white paint
12/4=3
So, to find the quarts of paint to be added in same ratio
3x3=9
Therefore, the answer according to the given ratio will be 9 quarts

For all of the graphs:
Start the point on the number that I got from the inequality.
A filled circle means:
Greater than or equal to or less than or equal depending on where the line goes.
A hallow circle means:
Greater than or less than also depending on where the line is pointed towards too.
In order to graph an inequality you have to find and simply first then graph it.
For example on number 1, K ≤ -4.
Let's graph!
As you can see I filled in the circle and started at the point, -4.
Once I did it I made it bold from -4 and there on to the left. Making -4 be greater than or equal to K.
I showed that -4 is greater than or equal to K by making the line bold behind -4, also by filling in the circle.

Using the data, create a histogram. i Got no clue
Answer:
Step-by-step explanation:
hope this helps!
As the answer is an histogram, you can see it in the image added.
What is histogram?A histogram is an approximate representation of the distribution of numerical data. A histogram is a graph that shows the frequency of numerical data using rectangles. The height of a rectangle (the vertical axis) represents the distribution frequency of a variable (the amount, or how often that variable appears).
here, we have,
An histogram is a graphical representation of data vs frequency.
On the x-axis we have de data. In this case the data are the number of hours that Trey worked during each of his eight shifts last pay period, 2.0,1.8, 4.6,1.1, 7.5,1.5,4.0,1.8. We need this data in order, so:
1.1
1.5
1.8
1.8
2.0
4.0
4.6
7.5
The data 1.8 is the only one that happened 2 times during his eight shifts.
So the frequency is 2. The frecuency of the other shifts is 1.
Now we have the elements to create the histogram.
On the x-axis we place the different hours of the shifts.
On the y-axis we place the frequency each hour occurred during the last pay period.
y(Frequency)

On Tuesday, there were 400 customers at a movie theater, and each customer paid $8 for a ticket. On Wednesday, the owner of the movie theater reduced the regular ticket price from $8 to $6 for tickets that were purchased before 6 p.m. If the daily ticket sales for the two days were the same, and 100 people paid $8 for a ticket on Wednesday, how many people paid $6 for a ticket on Wednesday?
Answer:
400
Step-by-step explanation:
6x + 800 = 3200
6x = 3200 - 800
6x = 2400
= 2400 / 6
x = 400
Hope this answer helps you :)
Have a great day

The number of people who paid $6 for a ticket on Wednesday are 300.
What is subtraction?The act or process of subtracting is a mathematical operation in which the difference between two numbers or quantities is calculated.
According to the given question.
Number of tickets sales for Wednesday = 400
Also, on Wednesday number of people who paid $8 for tickets = 100
Therefor,
The number of people or customer who paid $6 for a ticket on Wednesday = Total number of people who purchased tickets - total number of people who purchased tickets for $8
[tex]= 400 - 100\\= 300[/tex]
Hence, the number of people who paid $6 for a ticket on Wednesday are 300.

Match each event to the likelihood of its occurrence. rolling a six-sided die and getting a 7 randomly selecting a girl from a team of 14 boys and 4 girls randomly selecting a short straw from a set of 12 short straws and 12 long straws picking a bird from a list of 20 bird species and 6 other animals likely arrowRight impossible arrowRight unlikely arrowRight neither likely nor unlikely arrowRight
A six sided die has numbers 1 through 6 so getting a 7 is impossible so the probability would be 0 (impossible)
14 + 4 = 18 total boys and girls
Picking a girl would be 1/18 this is low so ( unlikely)
12 short and 12 long straws = 24 total straws. Picking a short one would be 12/24 = 1/2 this is in the middle ( neither likely nor unlikely)

There are 11 shirts to select from in a store.
How many ways can 5 different shirts be selected?
PLEASE HELP
Given:
Total number of shirts to select from in a store = 11
To find:
How many ways can 5 different shirts be selected?
Solution:
Number of to select r items from n items is:
[tex]^nC_r=\dfrac{n!}{r!(n-r)!}[/tex]
Total number of ways to select 5 different shirts from 11 shirts is:
[tex]^{11}C_5=\dfrac{11!}{5!(11-5)!}[/tex]
[tex]^{11}C_5=\dfrac{11\times 10\times 9\times 8\times 7\times 6!}{5\times 4\times 3\times 2\times 1\times 6!}[/tex]
[tex]^{11}C_5=\dfrac{11\times 10\times 9\times 8\times 7}{5\times 4\times 3\times 2\times 1}[/tex]
[tex]^{11}C_5=462[/tex]
Therefore, there are 462 ways to select 5 different shirts.
