Scientist are studying a bacteria sample. The function f(x)=360(1.07)^x gives the number of bacteria in the sample at the end of x days. Which statement is the best interpretation of one of the values of the function?
Options :
A. The initial number of bacteria is 7.
B. The initial of bacteria decreases at a rate of 93% each day.
C. The number of bacteria increases at a rate of 7% each day.
D. The number of bacteria at the end of one day is 360.
Answer:
C. The number of bacteria increases at a rate of 7% each day.
Step-by-step explanation:
Given the function :
f(x)=360(1.07)^x ; Number of bacteria in sample at the end of x days :
The function above represents an exponential growth function :
With the general form ; Ab^x
Where A = initial amount ;
b = growth rate
x = time
For the function :
A = initial amount of bacteria = 360
b = growth rate = (1 + r) = 1.07
If ; (1 + r) = 1.07 ; we can solve for r to obtain the daily growth rate ;
1 + r = 1.07
r = 1.07 - 1
r = 0.07
r as a percentage ;
0.07 * 100% = 7%

Question 10(Multiple Choice Worth 1 points)
(05.02 LC)
A student wants to report on the number of books her friends read each week. The collected data are below:
0 24 1 4 5 2 5 4
Which measure of center is most appropriate for this situation, and what is its value?
Median; 2
Median; 4
Mean; 2
Mean; 4
Step-by-step explanation:
Given that the set of data collected has an extreme value (24), a Median measure of center is more appropriate than a Mean measure.
We sort the same data collected in increasing order:
{0, 1, 2, 4, 4, 5, 5, 24}
There are 8 elements inside the set, so we check the 4th and 5th elements (closest to the center), which are 4 and 4.
Since they are equal, the Median is 4.
Our answer is Median; 4.
Answer:
median 4

Calculate ZQRP

Р
R
18 cm
Answer:
<QRP = 48.2°
Step-by-step explanation:
Given:
PR = 18 cm
QR = 12 cm
Required:
<QRP = angle R
Solution:
Reference angle = <R (<QRP)
Adjacent side length = 12 cm
Hypotenuse = 18 cm
Thus:
Cos (R) = 12/18
cos (R) = 0.6667
[tex] R = Cos^{-1}(0.6667) [/tex]
[tex] R = 48.1871227 [/tex]
<QRP = 48.2° (nearest tenth)

Mr. Peters made 5000 milliliters of fruit punch for a luncheon how many liters of fruit punch did she make
Answer: She made 5 liters of punch for a lunch.
Step-by-step explanation:
We know that,
1 liter = 1000 milliliters
Then, 1 milliliter = [tex]\dfrac{1}{1000}[/tex] liters
We are given that,
Mr. Peters made 5000 milliliters of fruit punch for a lunch.
i.e. in liters, it will be [tex]\dfrac{5000}{1000}[/tex] liters.
i.e. in liters, it will be 5 liters.
i.e. She made 5 liters of fruit punch for a lunch.
Hence, she made 5 liters of fruit punch for a lunch.

Sara is building a fence that will be 7 miles long when it is completed. Sara has finished building 2/3 of the fence. What is the length of fence (in miles) that Sara still needs to build to complete the fence?
Answer:
7/3 ft
Step-by-step explanation:
Given data
Lenght of fence= 7 miles
Amount completed= 2/3 of the total length
let us find the amount completed already = 2/3*7= 14/3 miles
Hence the length of fence remaining for completion is
=7- 14/3
=21-14/3
=7/3
Hence the amount in length undon is 7/3 ft

Kelly's new snowboard is 120% longer than her old snowboard. If the new snowboard is 150 cm, how long is her old snowboard?
12.5 Step-by-step explanation: My friend helped me
The length of Kelly's old snowboard is 125 cm long.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
For this case, let we suppose that:
x = length of Kelly's old snowboard (in cm)
Then, as we know that: new snowboard is 120% longer than her old snowboard, thus:
[tex]\dfrac{x}{100} \times 120 = \text{Length of new snowboard} = 150[/tex]
or
[tex]\dfrac{x}{100} \times 120 = 150\\\\\text{Multiplying 100/120 on both the sides}\\\\x \times \dfrac{120}{100} \times \dfrac{100}{120}= 150 \times \dfrac{100}{120}\\\\x \times 1 = x = \dfrac{150 \times 100}{120}\\\\x = \dfrac{15000}{120} = 125 \: \rm cm[/tex]
Thus, the length of Kelly's old snowboard is 150 cm long.

Function g is defined as g(x) = 2f(x – 4) + 3. What is the domain of function g?
OA. {xl -♾ < x <♾}
OB. {x|0 < x <♾}
OC. {x] -4 < x < ♾}
OD. {x|4 < x <♾}
Answer:
OB
because domain is all X values that satisfy graph. And on graph X has all +ve values going to infinity.
When the Function g is defined as g(x) = 2f(x – 4) + 3 so the domain of the function g is OB. {x|0 < x <♾}.
Calculation of the domain of the function g:Since the Function g is defined as g(x) = 2f(x – 4) + 3
So here OB should be considered as the domain of the all x values should satisfied the graph. Also, on graph X it contains the positive values that goes to infinity.
Hence, When the Function g is defined as g(x) = 2f(x – 4) + 3 so the domain of the function g is OB. {x|0 < x <♾}.

what is the y intercept of the function f(x)=2*5^x+4 please leave an explanation options- 2 4 6 14
Answer:
y intercept is 6
Step-by-step explanation:
Given:
[tex]f(x) = 2(5^x) + 4[/tex]
Required:
Determine the y intercept
To do this, we simply set x to 0
Substitute 0 for x in [tex]f(x) = 2(5^x) + 4[/tex]
[tex]f(0) = 2(5^0) + 4[/tex]
Evaluate the exponent, [tex]5^0[/tex]
[tex]f(0) = 2(1) + 4[/tex]
Open bracket
[tex]f(0) = 2 + 4[/tex]
[tex]f(0) = 6[/tex]
Hence, the y intercept is 6
