Given:
The graph of an exponential function.
To find:
The function in the form of [tex]f(x)=ab^x[/tex].
Solution:
The general form of an exponential function is
[tex]f(x)=ab^x[/tex] ...(i)
From the given graph it is clear that the function passes through the points (0,4) and (1,7). It means these points will satisfy the function.
For x=0 and f(x)=4,
[tex]4=ab^0[/tex]
[tex]4=a(1)[/tex]
[tex]4=a[/tex]
For x=1 and f(x)=7,
[tex]7=ab^1[/tex]
Putting a=4, we get
[tex]7=4(b)[/tex]
[tex]\dfrac{7}{4}=b[/tex]
Substitute a=4 and [tex]b=\dfrac{7}{4}[/tex] in (i).
[tex]f(x)=4\left(\dfrac{7}{4}\right)^x[/tex]
Therefore, the required exponential function is [tex]f(x)=4\left(\dfrac{7}{4}\right)^x[/tex].

Answers
This question is incomplete, the complete question is;
For integers a, b and k, we know that a > 12, b < 20 and a < b. If b=7k, what is the value of k ?
Answer: the value of k = 2
Step-by-step explanation:
Given that;
a > 12
b < 20
a < b
If b = 7k
Now if k = 1 {b = 7k = 7}
b would be equal to 7 but b has to be greater than 20
IT CANT BE
if k = 2 { b = 7k = 14}
b would be equal to 14, a is greater than 12, b has to be less than b; 14 < 20,
a has to be less than than b ( 12 < 14 )
IT IS
if k = 3 {b = 7k = 21}
b would be equal to 21, so b is greater than 20 and a is less than 21
IT CANT BE
Therefore the value of k = 2

problems; e.g. 200 bottles of equal capacity hold 350 litres of water.
How much water does each bottle hold?
Answers
Each bottle holds 1.75 liters of water.
To determine how much water each bottle holds, we can divide the total amount of water by the number of bottles.
Given that 200 bottles hold 350 liters of water, we divide 350 liters by 200 bottles:
350 liters / 200 bottles = 1.75 liters per bottle
Therefore, each bottle holds 1.75 liters of water.Therefore, each bottle holds 1.75 liters of water.
This means that if we were to fill each bottle to its maximum capacity, it would hold 1.75 liters of water.
It's important to note that this assumes each bottle has an equal capacity and that the water is evenly distributed among them.

Jenn is preparing brown rice. She needs 1 1 2 cups of brown rice and 2 cups of water. Jenn has only a 1 8 -cup measuring cup. How many 1 8 -cups each of rice and water will Jenn use to prepare the rice?
Answers
Answer:
She will need 12 1/8 cups of brown rice and 16 1/8 cups of water.
Step-by-step explanation:
You will want to convert 1 1/2 cups into an improper fraction, as well as 2 cups.
1 1/2 = 3/2
2 = 2/1
Now that you have done that you will then have to find a common denominator. You will need to list the multiples for 8 and lowest common factor so you don't have to simplify at the end.
The multiples of 8: 1, 2, 4, and 8
As shown above 2 is a multiple of 8. Therefore you will need to multiply the denominator by 4. This is because 2 x 4 equals 8. So now the denominator is 8. You will now need to multiply the numerator by 4 because that is what you multiplied the bottom by. It will be 3 x 4, and will therefore equal 12. The final improper fraction will be 12/8. The numerator then becomes the answer because that is the amount of 1/8 cups that you will need.
You then repeat this with 2/1. However you will need to multiply the denominator by a different number because it is 1. Looking at the multiples of 8 above, you will multiply the 1 by 8, therefore giving you 8 as the denominator. You will then multiply the numerator by 8 as well. This will result in an answer of 16. You will then have a 16/8. You will need 16 1/8 cups of water.

Step-by-step explanation:
Let L and T represent the initial amounts that Leo and Theo had. Let n represent the number of bills exchanged in the first exchange. Then we have ...
L -20n +50n = T -50n +20n . . . . after the first exchange, each has the same
After the second exchange, amounts trade places:
(L +30n) +6(50) = T
Substituting this into the first equation, we get ...
L +30n = ((L +30n) +300) -30n
30n = 300
n = 10
Leo gave Theo ten $20 bills.
_____
Comment on the amounts
Theo started with $600 more than Leo, including exactly 16 $50 bills. Leo had at least 10 $20 bills, so he could make the initial exchange. Whatever initial amount Leo had in excess of that $200 was matched in Theo's initial amount, but Theo must have had that excess in $20 bills only. For example, Leo may have started with $300 as 10×$20 +2×$50, but Theo's initial $900 would need to be 5×$20 +16×$50.

The required cumulative relative frequencies are 0.04, 0.44, 0.56, 0.80, and 1 respectively.
What is the relative frequency of the data?The relative frequency of the data is the ratio of the given frequency to the total frequency in the observation.
From the given data,
Relative frequency = given frequency / total frequency
Where total frequency = 0.04 + 0.4 + 0.12 + 0.24 + 0.2 = 1
Value Relative frequency Cumulative frequency
3 0.04/1 = 0.04 0.04
4 0.4/1 = 0.4 0.04 + 0.4 = 0.44
5 0.12 0.44 + 0.12 = 0.56
6 0.24 0.56 + 0.24 = 0.80
7 0.2 0.80 + 0.2 = 1
