Write an exponential function to model the following situation.
A population of 130,000 grows 3% per year for 16 years.
How much will the popluation be after 16 years?
Write an exponential function in terms of x.
y=10
Answers
Answer:
y = 130,000(1.03)ˣ
Step-by-step explanation:
The general form of an exponetial function is y = abˣ, where a is the initial value (when x = 0), and b is the multiplier (the growth or decay factor). Here, we start with a population of 130,000, so our initial value a = 130,000. A growth of 3% each year represents a growth factor of 1.03, so after x years, the population y should be y = 130,000(1.03)ˣ.
The exponential function in terms of x and y is y = 130,000(1.03)ˣ
What is an exponential function ?The exponential function is a mathematical function denoted by
y = abˣ
where a is the initial value (when x = 0)
and b is the multiplier (the growth or decay factor).
population starts from 130,000, so
Initial value a = 130,000.
A growth of 3% each year represents a growth factor of 1.03,
so after x years, the population y should be
y = 130,000(1.03)ˣ
Therefore , The exponential function in terms of x and y is y = 130,000(1.03)ˣ

Which linear inequality is represented by the graph? O y>2/3x-1/5 O y>3/2x+1/5 O y<2/3x+1/5 O y<3/2x-1/5
Answers
Answer:
Step-by-step explanation:
What you must do for this case first is to find the equation of the line.
We have then that by substituting the values of x = 0 and x = 3 we obtain:
y = 0.2
y = 2.2
Respectively.
So, the line is:
y = 2 / 3x + 1/5
Then, the points that satisfy the inequality are all those of the shaded region.
Answer:
The inequality is:
y ≤ 2 / 3x + 1/5

The height of the center of this circular clock (x - 4)² + (y - 7)² = 1, is 7 meters above the ground.
What are the types of equations of a circle?The equation for a circle has the generic form x² + y² + 2gx + 2fy + c = 0.
The standard equation of a circle is x² + y² = r².
The polar form of the equation of the circle is (rcosθ)² + (rsinθ)² = p².
We know the standard formula of a circle is x² + y² = r² centered at the origin.
Now, (x - h)² + (y - k)² = r² represents a circle centered at (h, k).
Given, The equation (x - 4)² + (y - 7)² = 1, with units in meters, represents the location of the clock relative to the bottom left corner of the wall.
Therefore, (4, 7) is the center of the clock in the x-y axis when the y-axis represents height so it is 7 meters above the ground.

Two parallel lines are cut by a transversal as shown below.
Suppose m<8=109. Find m<2 and m<3.
Answers
Answer:
measure 2 has to be 109 due to the alternate interior angles theorem. Measure 3 has to be 71 due to the supplementary angles theorem.
Angles 8 and 2 are alternate interior angles so they will be the same therefore,m∠2 and m∠3 will be 109° and 71° respectively.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—is known as the vertex.
Given two parallel lines a transversal.
Angles 8 and 2 are alternate interior angles.
m∠8 = m∠2
m∠2 = 108°
Now,m∠2 and m∠3 are supplementary angles.
Therefore,m∠3 = 180° - 108° = 71°
Hence "Angles 8 and 2 are alternate interior angles so they will be the same therefore,m∠2 and m∠3 will be 109° and 71° respectively".

Step-by-step explanation:

The trig ratio you would use is the one that relates the angle to the side opposite the angle and the hypotenuse.
That is the definition for the Sine.
Enter equations one at a time in order to send a line

Answers
Answer:
y = x + 3
y = 3x + 1
Step-by-step explanation:
This does it in two equations.
y = x + 3 and y = 3x + 1 equation will send 2 different lines through the coins to capture them
using the slope intercept equation,
y = mx + b
m = slope
b = y-intercept
let's pick 2 coordinate from the graph,
(-2, 1)(-1, 2)
m = 2 - 1 / -1 - (-2) = 1 / 1 = 1
1 = -2 + b
b = 3
Therefore,
y = x + 3
let check for another equation that will work for another line. Let's use the coordinates (-1, -2)(0, 1) to find slope.
Therefore,
m = 1 - (-2) / 0 - (-1) = 3 / 1 = 3
y = 3x + b
1 = 3(0) + b
b = 1
y = 3x + 1
