A county planner is looking at trends in population growth for two towns, Hapville and Merton. The population of Hapville in the year 2000 was 18,000. Since then, the population has increased at a steady rate of 500 per year. The population of Merton is increasing according to the equation y=12,000(1.04)t , where y = the population in thousands and t = the number of years since the year 2000. If these trends continue, how will the populations of the two towns compare in 2030?
Answer:
Merton will have about 6,000 more people than Hapville
Step-by-step explanation:
Merton
y = 12,000(1.04)^(30)
y = 12,000(3.24339)
y = 38,920.77012
Hapeville
y = 18,000 + (30 x 500)
y= 18,000 + 15,000
y = 33, 000
Merton - Hapeville
38,920.77012 - 33,000 = 5920.77012
Therefore Merton will have about 6,000 more people than Hapville

determine the initial value
Answer:
The initial (x, y) value of the data is (0, 16)
Step-by-step explanation:
The given data is presented here as follows;
[tex]\left\begin{array}{cc}x&y\\-5&6\\-4&8\\-3&10\\-2&12\\-1&14\end{array}[/tex]
From we data, we have a common first difference in the 'y' values of 2, therefore, we have a straight line graph
The slope of the graph, m = (14 - 6)/(-1 - (-5)) = 2
The equation of the straight line graph in point and slope form is;
y - 14 = 2 × (x - (-1)) = 2 × (x + 1)
Therefore, the equation of the straight line graph in slope and intercept form is given as follows;
y - 14 = 2 × (x + 1)
y = 2·x + 2 + 14 = 2·x + 16
y = 2·x + 16
The initial value of the graph when x = 0 is therefore given as follows;
y = 2·x + 16 = 2 × 0 + 16 = 16
y = 16 when x = 0
The initial value of the graph is (0, 16)
Therefore, the initial value of the given data is x = 0, y = 16.

Determine the area, in square units, of the triangle below. Round your answer to one decimal place.
1.53
26°
1.22
Answer:
Area =0.41 units^2
Step-by-step explanation:
sin 26 degrees=height/1.53
height=.438371 x 1.53=0.67
Area =(1/2)(0.67)(1.22)=0.41 units^2
One bag contains black, red and green pearls in a ratio of 3: 2: 7 A random account is drawn from the bag. Exercise routine a P (red)
Answer:
P(red) = 1/6
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
One bag contains black, red and green pearls in a ratio of 3:2:7.
So
[tex]\frac{3}{3+2+7} = \frac{3}{12}[/tex] of the pearls are black
[tex]\frac{2}{3+2+7} = \frac{2}{12}[/tex] of the pearls are red.
[tex]\frac{7}{3+2+7} = \frac{7}{12}[/tex] of the pearls are green.
P (red)
For each 12 pearls, 2 are red. So
P(red) = 2/12 = 1/6
Find the surface area and volume of the cone .
Answer:
Surface area of a cone = πrs + πr2
Volume of a cone = 1/3πr2h.
The slant of a right circle cone can be figured out using the Pythagorean Theorem if you have the height and the radius.
Answers for volume problems should always be in cubic units.
Step-by-step explanation:
A parabola can be drawn given a focus of (-10,1) and a directrix of x = -6. What can be said about the parabola?
Answer:
The characteristics of the parabola are;
1) The vertex of the parabola, (h, k) = (-8, 1)
2) The parabola opens left
3) The axis of symmetry is, y = 1
4) The equation of the parabola is x = -y²/8 + y/4 - 65/8
5) The end points of the latus rectum are (-10, -3), and (-10, 5)
Step-by-step explanation:
The focus of the parabola = (-10, 1)
The directrix of the parabola, x = -6
The directrix; x = h - p
The focus, F(h + p, k)
Therefore, we have;
h + p = -10
h - p = -6
2·h = -16
h = -8
p = -10 - h = -10 - (-8) = -2
p = -2
Therefore, we have;
1) The vertex of the parabola, (h, k) = (-8, 1)
2) Therefore, the parabola opens left
3) The axis of symmetry is the line y = 1
For P < 0, the equation of the parabola is of the form (y - k)² = 4·p·(x - h)
Therefore, the equation of the parabola is (y - 1)² = 4×(-2)×(x - (-8))
(y - 1)² = 4×(-2)×(x - (-8)) = y² - 2·y + 1 = -8·x - 64
∴ y² - 2·y + 1 + 64 = -8·x
x = -y²/8 + y/4 - 65/8
4) The equation of the parabola is x = -y²/8 + y/4 - 65/8
5) The end points of the latus rectum are (h + p, k + 2·p) and (h + p, k - 2·p)
Therefore, the end points of the latus rectum of the given parabola are;
(-8 + (-2), 1 + 2×(-2)) and (-8 + (-2), 1 - 2×(-2))
(-10, -3), and (-10, 5)
Kelly filled up her 14 gallon gas tank for $29.26. What if the tank is 17 gallons, how much does she have to pay?
Answer:
$35.53
Step-by-step explanation:
1. Divide what Kelly paid by the amount of gallons she paid for.
a. 29.26 divided by 14 = 2.09
2. Take the amount per gallon and multiply it by 17.
a. 17 times 2.09 = 35.53
So it will be $35.53 for 17 gallons of gas.
Answer:
35.53
Step-by-step;
So Kelly got 14 gallons of gas for 29.26. She is wondering how much it would be to fill it up to 17 gallons. So what you have to do is first find out how much the gas cost per gallon. so you would divide 29.26 by 14 to get 2.09. so now that you have how much it is per gallon all you have to do is multiply the amount per gallon {2.09} by 17. so when you multiply 2.09 by 17 you get 35.53. So Kelly had to pay 35.53 for a 17 gallon tank of gas!
Hope this helps you!

Actually Welcome to the Concept of the parallel,lines
Since both the angles are corresponding angles, hence they are equal,so we get as,
7x+40 = 3x+112
===> 7x - 3x = 112-40
===> 4x = 72
===> x = 72/4 => 18
hence x = 18°
now angle A = 7(18)+40
A = 166°
hence, A = 166°
5 - 3 x = 2 - 6 (X + 2)
Answer:
X = -5

Which inequality represents the stated situation : A theater is made to receive no more than 750 spectators. Group of answer choices
Answer:
C. s ≤ 750
Step-by-step explanation:
A. s≥750
B. s=750
C. s≤750
D. s<750
'no more than' in inequality means "less than or equal to"(≤) which means that the quantity could be less than or equal to.
From the question given, the theater can only receive less than 750 spectators or 750 spectators but no more than 750 spectators
The statement can be represented by the inequality;
s ≤ 750
Where
s means spectators

plzzzzz answer thiss I REALLY NEED ITTTTTTTTTTT
Answer:
The solution would be (3,2)
Step-by-step explanation:
Now the equation to find the graph does not matter to find the solution right now. Only the graph will be need as long as the graph is already filled. To find the solution, all you have to do is find the point where the two lines cross. On this graph, you can see that point in the two lines where there is a circle.
The temperature ′ t ′ is at least 30°F
