What is the formula of exponential growth?"[tex]f(x)=ab^x[/tex],
where a is the initial value
b is the growth rate
x is time. "
For given question,
Suppose the function for the population growth is,
[tex]A(t)=A_0\times b^t[/tex]
A colony of insects doubles every day.
⇒ b = 2
The colony has 5 insects today.
⇒ [tex]A_0=5[/tex]
So, the exponential growth function would be,
[tex]A(t)=5\times 2^t[/tex] ...........(1)
We need to find the number of insects after 20 days,
From equation (1),
[tex]\Rightarrow A(20)=5\times 2^{20}\\\\\Rightarrow A(20)=5\times 1048576\\\\\Rightarrow A(20)=5242880[/tex]
Therefore, 5242880 insects would be present in 20 days.
The correct answer is an option (c)

4 x 4 x •••4 =
7 times
find the base
The base of the given expression will be 4.
Here, we are given that 4 is multiplied by itself 7 times, that is-
4 x 4 x 4 x 4 x 4 x 4 x 4
As anything raised to the power 1 is the number itself, the given expression can also be written as follows-
[tex]4^{1} * 4^{1} *4^{1} *4^{1} * 4^{1} *4^{1} *4^{1}[/tex]
Now, we know that when we need to find the product of 2 numbers whose bases are same, we can simply add the powers. Mathematically this can be represented as follows-
[tex]a^{n}a^{m} =a^{n+m}[/tex]
Thus, the given expression will become-
[tex]4^{1} * 4^{1} *4^{1} *4^{1} * 4^{1} *4^{1} *4^{1}[/tex] = [tex]4^{1+1+1+1+1+1+1}[/tex]
= [tex]4^{7}[/tex]
Thus, we see that when 4 is multiplied 7 times, the base comes out to be 4 only.

HELP I HAVE TO FINISH IN 2 HOURS
shannon and sarah are mowing a field. shannon can finish mowing by herself in 2 hours. sarah can finish in 4 hours. how long will it take them to mow the field together?
Answer:
1h 20m
Step-by-step explanation:
Let the total amount of work be x.
Shannon:
2h = x
1h = [tex]\frac{1}{2}[/tex]x
So basically Shannon does [tex]\frac{1}{2}[/tex]x work per hour.
Sarah:
4h = x
1h = [tex]\frac{1}{4}[/tex]x
So basically Sarah does [tex]\frac{1}{4}[/tex]x work per hour.
Together:
1h = [tex]\frac{1}{2}[/tex]x + [tex]\frac{1}{4}[/tex]x
= [tex]\frac{2}{4}[/tex]x + [tex]\frac{1}{4}[/tex]x
= [tex]\frac{3}{4}[/tex]x
Amount of time spent = [tex]\frac{4}{4}[/tex]x ÷ [tex]\frac{3}{4}[/tex]x
= [tex]\frac{4}{4}[/tex]x × [tex]\frac{4}{3}[/tex]x
= [tex]\frac{16}{12}[/tex]h
= 1[tex]\frac{4}{12}[/tex]h
= 1h 20m
Answer:
4/3 hours
Step-by-step explanation:
For every hour that Sarah mows, Shannon mows twice as much. Because of this, Sarah is going to mow two times as much of the field as Shannon. You can set up an equation where x is the fraction of lawn mowed. This equation should be:
2x + x = 1 -> 3x = 1
The reason the equation is set up like this is because there is 1 whole lawn that the fraction of the lawn that Shannon mows (2x) plus the fraction of the lawn that Sarah mows (x) adds up to. You can use this equation to solve for x, which will be 1/3.
Since you know x, you can find what fraction of the lawn Shannon and Sarah mow. Since Shannon mows a fraction of 2x of the lawn, the fraction she mows will be 2*1/3 = 2/3. The fraction that Sarah mows will be x = 1/3.
Now that you know the fraction of the whole lawn that both Saran and Shannon mow, you can multiply their respective fraction by the amount of time it takes for them to mow a whole lawn. To do this for Shannon, you multiply 2/3 of the lawn by 2 hours, which gives you 4/3 hours. To do this for Sarah, you multiply 1/3 of the lawn by 4 hours, which also gives you 4/3 hours.

The complete sequence is 24, 30, 36, 42, 48, 54, 60
The nth term of an arithmetic progressionThe nth term of an arithmetic progression is expressed according to the equation;
Tn = a + (n-1)d
where
a is the first term
n is the number of terms
d is the common difference
Determine the common difference
d = 42-b = b - 30

What is the slope of a line on a standard xy-plane that passes through the point (1, 3) and (4,-3)?
A.) -1
B.) 2
C.) -2
D.) 1/2
E.) - 1/2
Therefore, the slope of a line on a standard XY-plane that passes through points (1, 3) and (4,-3) is -2.
So, option (c) is correct.
Given two points are (1, 3) and (4, -3)
We need to find the slope of a line
The slope of a line (m) :
m = y₂ - y₁ / x₂ - x₁
Given (x₁, y₁) = (1, 3) and (x₂, y₂) = (4, -3)
Slope (m) = y₂ - y₁ / x₂ - x₁
= -3 - 3 / 4 - 1
= -6 / 3
= -2
Therefore, the slope of a line on a standard XY-plane that passes through points (1, 3) and (4,-3) is -2.
So, option (c) is correct.

URGENT!!! a media statistics agency reports that the mean number of televisions in a household in a particular country is 2.24 with a standard deviation of 1.38 what is the probability of a random sample of 40 households have a sample mean number of at least 2.55 televisions per household.
Answer:
0.48173
Step-by-step explanation:
Given that :
Mean (m) = 2.24
Standard deviation (s) = 1.38
Sample size (n) = 40
P(x ≥ 2.55)
Z = (x - m) / (s/sqrt(n))
Z = (2.55 - 2.24) / (1.38 / sqrt(40))
Z = 0.01 / 0.2181971
Z = 0.0458301
P(Z ≥ 0.0458) = 0.48173 ( Z probability calculator)
