The bacteria in a culture double every day. Which function can be used to find the number of bacteria n after d days if there are initially 75 bacteria?
On=2(75)
O n = 75(g)
On = 75(2)
On= (75)"
Answers
Answer:
n = 75(2)^d
Step-by-step explanation:
Mathematically, we have the general form of an exponential equation as follows;
y = I(1 + r)^x
where I is the initial value
r is the rate percentage
x is the number of time
From the question, the bacteria population doubles
This mean it increases by 100%
100% = 1
add this to the initial 1, and we have 2
Replace I with the number 75
And d represents the days
so we have;
n = 75(2)^d

What is the trigonometry function?
Trigonometric functions are also known as Circular Functions can be simply defined as the functions of an angle of a triangle.
It means that the relationship between the angles and sides of a triangle are given by these trig functions.
Here given that,
In the trigonometry functions it intersects its midline at [tex](8.7, 7.2)[/tex], and it has a minimum point at [tex](6.2,3.8)[/tex].
So,
[tex]7.2 - 3.8=3.4[/tex]

1. Find the present value of an investment that is worth $19,513.75 after
earning 3% simple interest for 5 & 1/2 (5.5) years.
2. Mr. Clopu buys an 18-month CD that pays 4 3/4% simple interest for $5,000. Find the value of the CD at the end of its term.
Answers
1) To get the present value, we need to get the amount after 5.5years
Amount = Principal + Interest
Interest = PRT/100
Interest = $19,513.75*3*5.5/100
Interest = 321,976.875/100
Interest = $3219.76875
Amount = $19,513.75+$3219.76875
Amount = 22,733.51875
Hence the present value is $22,733.51875
2) Simple Interest = PRT/100
Simple Interest = 5000*(4 3/4)* 18/12*100
Simple interest = 5 * 19 * 18/4*12
Simple interest = 1710/48
Simple interest =35.625
Amount = 5000 + 35.625
Amount = $5035.625
Hence the present value is $5035.625
Mr. barrera has 2 bags of cat food. One bag has 20 ounces and the other has 3 1/2 times as much as the first bag. If Mr. Barrera uses 1/5 of the cat food from the larger bag to feed his cats, how many ounces of cat food did he use?
Answers
Answer: 14 oz
Step-by-step explanation: Trust me it’s right
The number of ounces of cat food that Mr. Barrera used is; 14 Ounces (Oz)
Number of bags with cat food = 2 bagsNumber of ounces in first bag = 20 OzOther bag has 3½ times as much as first bag. Thus;
Number of ounces in second bag = 3½ × 20 = 70 Oz
He uses 1/5 of the cat food from the larger bag.
Thus;
He used; 1/5 × 70 = 14 Oz of cat food
