defines the population t years after 2010?
O P= 45, 2302
OP=45, 230(1+0-2)*
OP=45, 2300
OP=45, 230(1 +0.02)
Answer:
C
Step-by-step explanation:
The following equation defines the population t years after 2010,
P = 45230(1 + 0.02[tex])^{t}[/tex].
What is Exponential Growth?An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases over time.
y = a(1+r)ˣ,
where a is the initial population and r is the rate in decimals and sx is the time period.
Given:
The population in Small town in 2010 was 45,230 people and is growing exponentially at a rate of 2 percent.
The formula;
y = a(1+r)ˣ,
where a is the initial population and r is the rate in decimals and x is the time period.
That means,
P = 45230(1 + 0.02[tex])^{t}[/tex]
Therefore, the equation is P = 45230(1 + 0.02[tex])^{t}[/tex]

What is the value of x?
What is the value of z?
What is tue value of y?
Answer:
x is equal to 55
y is equal to 70
z is equal to 55
Step-by-step explanation:
You can see that x is equal to (180 - 125)°, because x° and the 125° mark form a single line.
So x is equal to 55.
Also, because of the markings on the two sides of the triangle, we can see that it's an Isosceles triangle, meaning x and z are equal, so z too is equal to 55.
Finally, knowing that the sum of the angles inside any triangle is 180°, y then must equal (180 - 55 - 55)°, or 70°

Faried is planting a flower garden. He plants 3 lilies for every 4 rose bushes. If Faried plants 12 lilies, how many rose bushes did he plant?
Answer:
16.
Step-by-step explanation:
There are 12 lillies which means that Faried planted 4 rows of rose bushes because 12 divided by the 3 lillies is four. 4x4= 16 rose bushes
The number of rose bushes planted is A = 16 bushes
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
Let the number of lilies planted be = 3 lilies
The number of rose bushes planted for 3 lilies = 4 bushes
Now , the new number of lilies planted = 12 lilies
And , the proportion is
number of lilies planted / number of rose bushes planted for 3 lilies = the new number of lilies planted / A
Multiply by A on both sides , we get
A ( 3/4 ) = 12
Divide by 3 on both sides , we get
A / 4 = 4
Multiply by 4 on both sides , we get
A = 16 bushes
Hence , the number of rose bushes is 16

Convert to slope intercept form 4x+5y=-20
Answer:
Slope-intercept form is: y=mx+b. Where m = slope or rise/run & b = y-intercept or where the line crosses the y axis. So for 4x + 5y = 20 the slope intercept form is y = -4x/5 + 4.
Step-by-step explanation:
Answer:
y = -4/5x - 4
Step-by-step explanation:
4x + 5y = -20
-4x -4x
5y = -4x - 20
divide it all by 5
y = -4/5x - 4

A firefighter extends a ladder against the side of a house. The ladder makes a 32°\degree° angle with the ground. The base of the ladder is 25 feet from the house. Find how high the ladder reaches up the side of the house to the nearest tenth of a foot.
*Draw and label a picture, set up an equation, and solve*
Answer:
29.5 feet
Step-by-step explanation:
A firefighter extends a ladder against the side of a house. The ladder makes a 32°\degree° angle with the ground. The base of the ladder is 25 feet from the house. Find how high the ladder reaches up the side of the house to the nearest tenth of a foot.
We solve using Trigonometric function of Cosine
= cos theta = Adjacent/Hypotenuse
Theta = 32°
Adjacent = 25 feet
Hypotenuse = Height of the ladder
= cos 32 = 25/x
x = 25/cos 32
x = 29.479460084 feet
Approximately= 29.5 feet
Solve for x in the figure below
Answer:
x = 6.8
Step-by-step explanation:
7x + 36 = 12x + 2 (alternate interior angles are congruent)
Collect like terms
7x - 12x = -36 + 2
-5x = -34
Divide both sides
-5x/-5 = -34/-5
x = 6.8

In exercises 4-6, a survey reported that 235 of the 500 voters in a sample voted for candidate A and the rest voted for candidate B?
4. What percent of the voters in the sample voted for candidate A? What percent of the voters in the sample voted for candidate B?
5. What is the margin sampling error? Round your answer to the nearest tenth of a percent.
6. For each candidate, give an interval that is likely to contain the exact percent of all voters who voted for the candidate.
7. For #6, can you determine which candidate won? Explain.
4.
Total voters = 500
Number of voters that voted for candidate A = 235
Number of voters that voted for candidate B = 500 - 235 = 265
Percent of voters that voted for candidate A
= 235
500
× 100%
= 23500
500
= 47%
Percent of voters that voted for candidate B
= 265
500
× 100%
= 26500
500
= 53%
5.
Margin sample error = % of candidate B - 5 of candidate A
= 53% - 47%
= -/+ 6%
Margin sample error = + 6.0% or - 6.0%
6.
Candidate A interval
= 47 ± 0.5
= 46.5% or 47.5%
Candidate B interval
= 53±0.5
= 52.5% or 53.5%
7.
Candidate with the highest percentage win.
Therefore, candidate B won
