A population of bacteria is treated with an antibiotic. It is estimated that 5,000 live bacteria existed in the sample in
before treatment. After each day of treatment, 40% of the sample remains alive. Which best describes the graph of
the function that represents the number of live bacteria after x days of treatment?
Answer:
The answer is A. f(x) = 5000(0.4)x, with a horizontal asymptote of y = 0, because 2,000 of the bacteria remain alive.
Step-by-step explanation:
Answer:
The correct option is A.
Step by step explanation:
The exponential function is defined as
Where, a is initial value and b is growth factor or decay factor.
The initial population of bacteria is 5000.
After each day of treatment, 40% of the sample remains alive. It means the growth factor or decay factor is
Therefore the required function is
The horizontal asymptote is y=0 because
Therefore option A is correct.

A snail travels at a rate of 2.37 feet per minute.
a. Write a rule to describe the function.
b. How far will the snail travel in 6 minutes
A. d(t) = t/2.37; 2.53ft
B. d(t) = t + 2.37; 8.37 ft
C. d(t) = 2.37t; 14.22 ft
D. d(t) = 6t; 14.22 ft
Answer:
C. d(t) = 2.37t; 14.22 ft
Step-by-step explanation:
2.37 per minute is multiplication so A and B are definitely wrong
Another way to check is 2.37*6=14.22 so the answer is C
Answer:
D. d(t) = 6t; 14.22 ft
Step-by-step explanation:
d(t)= 2.37t; 14.22 ft
d(t)= 2.37t; 14.22 ft
Answer:
a. f(t)=2.37t
b. 14.22 feet
Step-by-step explanation:
We are given that:
A snail travels at a rate of 2.37 feet per minute.
a. write a rule to describe a function.
Let t describe the time and f(t) be a function how far snail travels
then, f(t)=2.37×t
where the unit of t is in minutes and that of f(t) is feet
b. how far will the snail travel in 6 minutes
we have to find f(t) at t=6
f(6)= 2.37×6
= 14.22 feet
Hence, snail traveled 14.22 feet in 6 minutes
2.37/minute
14.22 feet in six minutes
Answer:
Rule for Distance is f(t) = 2.37t and distance covered in 6 minutes is 14.22 feet.
Step-by-step explanation:
Speed of Snail = 2.37 feet per minute
To write the rule we use relation of Speed, Distance and time
Distance = Speed × Time
So, Distance cover by snail in t minutes is given by f(t) = 2.37 × t
⇒ f(t) = 2.37t
Distance traveled by Snail in 6 minutes , f(6) = 2.37 × 6 = 14.22 feet
Therefore, Rule for Distance is f(t) = 2.37t and distance covered in 6 minutes is 14.22 feet.
A hot dog vendor at Wrigley Field sells hot dogs for $1.50 each. He buys them for $1.20 each. All the hot dogs he fails to sell at Wrigley Field during the afternoon can be sold that evening at Comiskey Park for $1 each. The daily demand for hot dogs at Wrigley Field is normally distributed with a mean of 40 and a standard deviation of 10.a. If the vendor buys hot dogs once a day, how many should he buy?b. If he buys 52 hot dogs, what is the probability that he will meet all of the day’s demand for hot dogs at Wrigley?
Answer:
43 ; 0.88493
Step-by-step explanation:
Using the Zscore formula :
Zscore = (x - m) / s
m = mean ; s = standard deviation
Profit = $1.5 - $1.2 = $0.3
Loss = $1.2 - $1 = 0.2
Cummlative probability :
Profit / (profit + loss)
0.3 / (0.3 + 0.2) = 0.3 / 0.5 = 0.6
To obtain the x, at Z at 0.6 = 0.26
m = 40 ; s= 10
Hence,
0.26 = (x - 40) / 10
0.26 * 10 = x - 40
2.6 = x - 40
2.6 + 40 = x
x = 42.6 `; 43 approximately
Probability of meeting day's demand at Wrigley
x = 52
P(x < 52) :
Zscore = (52 - 40) / 10
P(Z < 1.2)
Z = 0.88493

find the value of s when u = 14, a = 8 and t = 4. s=ut+1/2at^2
Answer:
s = 120
Step-by-step explanation:
Explanation:-
Given
[tex]s = ut + \frac{1}{2} at^{2}[/tex]
Substitute 'u =14 , a= 8 and t=4
[tex]s = 14 (4) + \frac{1}{2} 8(4)^{2}[/tex]
s = 56 + 64
s = 120

The number from the equation is less than 11
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number be = x
Now , the equation is
Sum of a number and 3 more than twice the number is less than 36
Let us assume the sum of the numbers is 36
So ,
x + 3 more than twice the number = 36
And ,
x + ( 3 + 2x ) = 36
On simplifying the equation , we get
3x + 3 = 36
Subtracting 3 on both sides , we get
3x = 33
Divide by 3 on both sides , we get
x = 11
But , the inequality equation is less than 36
So , x < 11
Therefore , the number is less than 11
Hence , the number from the equation is less than 11

Which pair of functions are inverses of eachother?
Answer:
D
Step-by-step explanation:
A.
y= 6x³
to find the inverse substitute x for y and y for x and solve for y
x= 6y³ ; divide both sides by 6
x/6 =y³ ; cube root both sides
(∛x)/ ∛6 = y
so (∛x)/6 and 6x³ are NOT inverse of each other
B
y= (x+2)/5
x= (y+2)/5; multiply by 5
5x = y+2; subtract 2
y= 5x-2 NOT corect
C
y = 5x-6
x= 5y-6; add 6 to both sides
x+6 = 5y ; divided by 5 both sides
y = (x+6)/5 is NOT correct
D
y=7x -2
x= 7y-2
x+2 = 7y , (x+2) /7 = y so IS correct

a new machine. When both machines work together, they require 9 hours
to complete a job. How many hours would it take the new machine to
finish the job operating alone?
Answer:
Step-by-step explanation:
[tex]9(r_n+r_o)=1\\ \\ r_n+r_o=\frac{1}{9}\\ \\ r_o=\frac{r_n}{3}\\ \\ r_n+\frac{r_n}{3}=\frac{1}{9}\\ \\ \frac{4r}{3}=\frac{1}{9}\\ \\ 4r=\frac{1}{3}\\ \\ r=\frac{1}{12}\\ \\ \text{So working alone it would take the new machine 12 hours to finish the job.}[/tex]
