Answer:
A.) P(t) = 130t +3330
B.) P(16) = 5410
Step-by-step explanation:
Given the ordered pairs (t, P(t)) = (2, 3590) and (9, 4500), you want a linear model that describes the relation. You also want the value of P(16).
A.) Linear modelWe can write the formula for P(t) starting with the point-slope equation for P in terms of t. To do that, we need the slope:
m = (P2 -P1)/(t2 -t1)
m = (4500 -3590)/(9 -2) = 910/7 = 130
The point-slope equation will be ...
P -P1 = m(t -t1)
P -3590 = 130(t -2)
Solving for P, we find ...
P = 130t -260 +3590 . . . . . eliminate parentheses, add 3590
P(t) = 130t +3330
B.) PredictionThe value of P(16) will be ...
P(16) = 130(16) +3330 = 2080 +3330 = 5410
The moose population is predicted to be 5410 in 2006.

Additional comment
The value of t is years since 1990, so the relevant values are ...
1992: t = 1992 -1990 = 2
1999: t = 1999 -1990 = 9
2006: t = 2006 -1990 = 16

What does the term "linear model" mean?
In a linear model, the terms are added rather than multiplied, divided, or provided as a non-algebraic function, as has been the case thus far in this section. A linear model is not just a straight line or its higher dimensional equivalent.Given the ordered pairs (t, P(t)) = (2, 3590) and (9, 4500), you want a linear model that describes the relation. You also want the value of P(16).
A.) Linear model
We can write the formula for P(t) starting with the point-slope equation for P in terms of t. To do that, we need the slope:
m = (P2 -P1)/(t2 -t1)
m = (4500 -3590)/(9 -2) = 910/7 = 130
The point-slope equation will be
P -P1 = m(t -t1)
P -3590 = 130(t -2)
Solving for P, we find
P = 130t -260 +3590 . . . . . eliminate parentheses, add 3590
P(t) = 130t +3330
B.) Prediction
The value of P(16) will be
P(16) = 130(16) +3330 = 2080 +3330 = 5410
The moose population is predicted to be 5410 in 2006.
(B) The value of t is years since 1990, so the relevant values are
1992: t = 1992 -1990 = 2
1999: t = 1999 -1990 = 9
2006: t = 2006 -1990 = 16

Paragraph 3: Today, most people use an app to get directions. What do you think it would have been like to drive without an app? Besides converting distances, what other kinds of math concepts might you need to use?
The link between map distance and ground distance is represented using a scale. One of two measurement techniques will most usually be applied to the map scale units.
What do we mean by a scale?
A scale is used to depict the relationship between map distance and ground distance.
Most frequently, one of two measuring methods will be used for the map scale units.
To put it another way, a map's scale establishes the distance between the map and the entire or a specific portion of the earth's surface that is depicted on it.
This relationship can also be expressed as a ratio between the distances between two spots on a map and their corresponding distances on the ground.
Although there are many different scales used in various industries, the purpose of weighing is always the same: to precisely quantify the material that makes up diverse things so that the number can be used for transportation.
Therefore, the link between map distance and ground distance is represented using a scale. One of two measurement techniques will most usually be applied to the map scale units.

suppose that two stars in a binary star system are separated by a distance of 80 million kilometers and are located at a distance of 170 light-years from earth.
A) What is the angular separation of the two stars in degrees?
B) What is the angular separation in arceseconds?
To calculate the angular separation of the two stars, we can use the formula:
Angular separation = (Distance between stars) / (Distance from Earth) * (180 / π)
A) Calculating the angular separation in degrees:
Distance between stars = 80 million kilometers
Distance from Earth = 170 light-years ≈ 1.60744e+15 kilometers
Angular separation = (80e+6) / (1.60744e+15) * (180 / π) ≈ 0.0022308 degrees
Therefore, the angular separation of the two stars is approximately 0.0022308 degrees.
B) To calculate the angular separation in arcseconds, we can use the conversion:
1 degree = 60 arcminutes
1 arcminute = 60 arcseconds
Angular separation in arcseconds = (Angular separation in degrees) * 60 * 60
Angular separation in arcseconds ≈ 0.0022308 * 60 * 60 ≈ 8.03 arcseconds
Therefore, the angular separation of the two stars is approximately 8.03 arcseconds.

The measure of angle SQR is 74
How to determine the value of SQP?The angles are given as
2m + 4 and 3m + 1
These angles are same side interior angles
So, we have
2m + 4 + 3m + 1 = 180
Collect the like terms
So, we have
2m + 3m + 4 + 1 = 180
Evaluate the like terms
So, we have
5m = 175
Divide both sides by 5
m = 35
Substitute m = 35 in SQR = 2m + 4
SQR = 2 x 35 + 4

A car initially going 63 ft/sec brakes at a constant rate (constant negative acceleration), coming to a stop in 7 seconds. Graph the velocity for t=0 to t=7 . How far does the car travel before stopping?
The car travels 220.5 feet before stopping.
To find the distance the car travels before stopping, we first need to determine the constant negative acceleration. We can use the formula vf = vi + at, where vf is the final velocity (0 ft/sec), vi is the initial velocity (63 ft/sec), a is the acceleration, and t is the time (7 seconds).
0 = 63 + 7a
-63 = 7a
a = -9 ft/sec²
Now, we can use the formula d = vi*t + 0.5*a*t² to find the distance (d).
d = (63 ft/sec)(7 sec) + 0.5*(-9 ft/sec²)(7 sec)²
d = 441 + (-220.5)
d = 220.5 ft
To graph the velocity from t=0 to t=7, plot a straight line with an initial velocity of 63 ft/sec and a constant negative slope of -9 ft/sec². The line will reach 0 ft/sec at t=7 seconds.

Sean is riding on a Ferris wheel that has a radius of 125 ft. About how far has Sean traveled after the Ferris wheel makes one full rotation??
The distance Sean has traveled after the Ferris wheel makes one full rotation is approximately 1,570 feet.
How far does Sean travel after completing one full rotation on the Ferris wheel?The circumference of a circle is calculated using the formula 2πr, where π is a constant approximately equal to 3.14 and r is the radius of the circle. In this case, the radius of the Ferris wheel is given as 125 ft. To find the distance traveled by Sean, we need to calculate the circumference of the Ferris wheel. Substituting the given radius into the formula, we have:
Circumference = 2π * 125 feet = 250π feet.
To find the distance Sean has traveled after one full rotation, we use the fact that the circumference represents the distance traveled in one complete revolution. Therefore, Sean has traveled approximately 250π ft, which is approximately equal to 1,570 ft.

Last month you purchased 6 individual songs and 1 albums for a total of $21.99.
This month you spent a total of $44.97 on 4 individual songs and 3 albums.
How much does each song and album cost
Answer:
Song =$1.50 Album =$12.99
Step-by-step explanation:
Lets assume Individual songs = x
albums=y
6x + y = 21.99-------- y= 21.99- 6x
4x + 3y= 44.97
Replace y in the second equation
4x+ 3(21.99-6x) = 44.97
4x +65.97- 18x = 44.97
14x= 21
x = 1.50
y= 21.99- (6*1.50)
= 12.99
