The exponential growth function is "[tex]y = 25(1.0167)^t[/tex]". A complete solution is below.
Given:
Population,
25Increasing rate,
r = 20%Now,
The value after 1 year will be:
= [tex]25+(\frac{20}{100} )25[/tex]
= [tex]25+\frac{1}{5}\times 25[/tex]
= [tex]25+5[/tex]
= [tex]30[/tex]
Now
→ [tex]25(1+\frac{R}{100} )^{12} =30[/tex]
→ [tex]R = 1.67[/tex]
hence,
The exponential growth rate to find the monthly growth rate will be:
→ [tex]y = 25(1.0167)^t[/tex]
Thus the above answer i.e., option C is the correct alternative.

The points represented by the (x, y) coordinate pairs all lie on line "k". These are the points: (1,3), (2, 1), (3,-1). (4.-3), and (5,-5). What is the slope of line k? A.2 B.5 C.-3 D.-2
Answer:a
Step-by-step explanation:
Bsnanna
If the points (1,3), (2, 1), (3,-1). (4.-3) lie on line k, then the slope of line k is -2
Option D is the correct choice
The points that lie on the line k are:
(1,3), (2, 1), (3,-1). (4.-3), and (5,-5).
We can find the slope of the line k by picking any two points on the line
The slope m of a line passing through the points (x₁, y₁) and (x₂, y₂) is given by the formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
On the line k, let us select the points (1,3) and (2, 1)
x₁ = 1, y₁ = 3, x₂ = 2, y₂ = 1
[tex]m = \frac{1-3}{2-1} \\\\m= \frac{-2}{1}\\\\m= -2[/tex]
Therefore, the slope of the line k is -2

Write the measure in descending order 0.5m - 480mm - 55cm
Answer:
480mm<55cm<0.5m
Step-by-step explanation:
millimeters means 100
centimeters means 10
meters means 1
there are 10mm in every 1cm and 100cm in every 1m
Answer:
55cm>0.5m>480mm
Step-by-step explanation:
as we know
1000mm=1m
100cm=1m
So we see
55=55cm
0.50=50cm
480=48cm

Thank you!
Answer:
Step-by-step explanation:
1. The probability that your mail is delivered before 2 pm is 0.9, so the probability that the mail is delivered at 2 pm or after 2 pm (so not before 2 pm) is 1-0.9=0.1.
Remark: 0.9=9/10=90/100=90%, and 0.1 is 10%

Consider the triangle below.
Determine the angle measure for the bottom two angles in order for the triangle to be classified as an isosceles triangle.
Answer:
angle 1= 30 degrees
angle 2= 120 degrees
angle 3= 30 degrees
Step-by-step explanation:
A triangle is equal to 180 degrees so first step is to subtract 120 to get the total of your two missing angles
180-120=60
and since your two missing angles are equal to each other you can divide by 2 and you get your two missing angles
60 / 2 = 30

A forest covers 73,000 acres. A survey finds that 0.2% of the forest is old-growth trees. How many
acres of old-growth trees are there?
There are acres of old-growth trees.
Type an integer or a decimal)
Answer:
143 acres.
Step-by-step explanation:
To find how many acres of old-growth trees there are, we need to find what 0.2% of 73,000 is.
To find a percent of a number, multiply the percent by the number.
0.2% is equal to 0.002.
73,000 x 0.002 = 143
So, 143 acres of the forest is old-growth trees.

Step-by-step explanation:
Colton has 888 comedy movies, 666 action movies, 555 fantasy movies, and 111 drama movie on his list of favorite movies. For every 555 movies on the list, there are 222 \_\_\_\_____\_, \_, \_, \_ movies.
Answer: Comedy
Step-by-step explanation:
Find out the percentages of each of the movies. First find the total quantity.
= 888 + 666 + 555 + 111
= 2,220 movies
Comedy = 888/2,220 * 100% = 40%
Action = 666 / 2,220 * 100% = 30%
Fantasy = 555/2,220 * 100% = 25%
Drama = 111/ 2,220 * 100% = 5%
222 movies out of 555 is:
= 222 / 555 * 100%
= 40%
222 movies out of 555 movies will therefore be comedy.
Answer:
222/555 are comedy

[tex]E(x) = 4.56[/tex] --- Mean
[tex]s^2 = 1.0944[/tex] --- Variance
[tex]s = 1.0461[/tex] --- Standard Deviation
Step-by-step explanation:
See Comment for missing details
Given
[tex]p = 0.76[/tex] --- proportion
[tex]n = 6[/tex] -- sample
Solving (a): The mean; E(x)
This is calculated as:
[tex]E(x) = n * p[/tex]
Substitute values for n and p
[tex]E(x) = 6 * 0.76[/tex]
[tex]E(x) = 4.56[/tex]
Solving (b): The variance; s^2
This is calculated as:
[tex]s^2 = n*p*(1-p)[/tex]
Substitute values for n and p
[tex]s^2 = 6 * 0.76 * (1-0.76)[/tex]
[tex]s^2 = 6 * 0.76 * 0.24[/tex]
[tex]s^2 = 1.0944[/tex]
Solving (c): The standard deviation; s
This is calculated as:
[tex]s = \sqrt{s^2[/tex]
Substitute value for s^2
[tex]s = \sqrt{1.0944[/tex]
[tex]s = 1.0461[/tex]

The value of y when the value of x is equal to the negative number 4 is negative 11 (-11).
What is an unknown variable?Unknown variables are used to find the unknown values of the problem using the algebraic expressions.
The expression for the variable x and y are given as,
[tex]y=2x-3[/tex]
The x value for the above expression is given as,
[tex]x=-4[/tex]
The value of y for the above value of x has to be found out. Put the value of x in the given expression to find the value of variable y as,
[tex]y=2(-4)-3[/tex]
Solve it further as,
[tex]y=2(-4)-3\\y=-8-3\\y=-11[/tex]

Step-by-step explanation:
The 4th term of the given geometric sequence is 54.
What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
The nth term of a GP is given as a[tex]r^{n-1}[/tex]
As per the given,
Common ratio r = 3
8th term = 4374
a(3)⁸⁻¹ = 4374
a = 2
The 4th term will be as, 2 x (3)⁴⁻¹ = 54
