Answer:
The answer is 7.199 x 10^4 hectares
Step-by-step explanation:
Let's set x as the total land area in 2017.
x * (1 + 6.4%) = 76,600
x * (1 + 0.064) = 76,600
x * 1.064 = 76,600
x = 76,600 / 1.064
x = 71,992.48
x = 7.199 * 10^4 hectares

What is Production Possibilities Curve (PPC)?
The Production Possibilities Curve (PPC) Sometimes called the production possibilities frontier (PPF) is a model used to show the tradeoffs associated with allocating resources between the production of two goods. The PPC can be used to illustrate the concepts of scarcity, opportunity cost, efficiency, inefficiency, economic growth, and contractions.
Due to the increase in resources of the country, the production capacity for both pineapple & coconut will increase as a result country's PPC will shift rightward/forward. And the country will achieve blue PPC.

The sine model is y = - 7 + 10 · sin (π · x/30 - π/2).
How to find sinusoidal functions from a given graph
Sinusoidal functions are periodic trascendent expressions which involves trigonometric functions. There are two kinds of sinusoidal functions:
[tex]y = A \cdot \cos (B\cdot x + C) + D[/tex] (1)
[tex]y = A\cdot \sin (B\cdot x + C) + D[/tex] (2)
Where:
A - AmplitudeB - Angular frecuencyC - Angular phaseD - MidpointFirst, we find the amplitude and the midpoint:
A = [3 - (- 17)]/2
A = 10
D = [3 + (- 17)]/2
D = - 7
Now we find the angular phase and the angular frequency for each model:
Cosine model (x, y) = (0, - 17), (x, y) = (30, 3)
- 17 = 10 · cos C - 7 (3)
3 = 10 · cos (30 · B + C) - 7 (4)
By (3):
- 10 = 10 · cos C
cos C = - 1
C = acos(- 1)
C = - π
And by (4):
3 = 10 · cos (30 · B - π) - 7
10 = 10 · cos (30 · B - π)
cos (30 · B - π) = 1
30 · B - π = acos 1
30 · B - π = 0
30 · B = π
B = π/30
The cosine model is y = - 7 + 10 · cos (π · x/30 - π).
Sine model
Obtain the sine model by using trigonometric expressions:
cos θ = sin (θ + π/2) (5)
By (5):
y = - 7 + 10 · sin (π · x/30 - π + π/2)
y = - 7 + 10 · sin (π · x/30 - π/2)
The sine model is y = - 7 + 10 · sin (π · x/30 - π/2).

A store sells both cold and hot beverages. Cold beverages, c, cost $1.50, while hot beverages, h, cost $2.00. On Saturday, drink receipts totaled $360, and 4 times as many cold beverages were sold as hot beverages.
Which system of linear equations represents the beverage sales on Saturday?
Answer:
There are two equations and two variables, so this is a system of linear equations.
c + h = 360
4c = h
Step-by-step explanation:
Answer:
The linear equations would be c = 4h and 1.5c + 2h = 360.
Step-by-step explanation:
First we have to create a table for our data.
c = total number of cold beverages sold.
h = total number of hot beverages sold.
The total cost of both beverages sold -
1.5c + 2h = 360
The amount of cold beverages -
c = 4h
Now we just need to substitute the second equation to the first one.
1.5 * (4h) + 2h = 360
= 6h + 2h = 360
= 8h = 360
= h = 45
Now we need to find the value of c.
c = 4* 45 = 180
Therefore 180 cold beverages were sold and 45 hot beverages were sold.
But the linear equations would be c = 4h and 1.5c + 2h = 360.

the Royal fruit company produces two types of fruit drinks the first type is 45% pure fruit juice and the second type is 95% pure fruit juice. the company is attempting to produce a fruit drink that contains 55% pure fruit juice how many pints of each of the two existing types of drink must be used to make 180 pints of a mixture that is 55% pure fruit juice
Answer:
first type: 144 pints
second type: 36 pints
Step-by-step explanation:
So let's try to interpret the given information. So the first thing to know is how to calculate x%, to calculate this, you simply multiply the number by x/100, which is what x is in decimal form.
So let's just start off by assigning variables to each brand, with the variable representing the amount of pints. Let's say "x" is the amount of pints of the first brand, and "y" is the amount of pints of the second brand.
The next thing to do is make equations using the given information. So we want a fruit drink that is 55% pure fruit juice, and it's 180 pints. So to find what 55% is, we multiply by 55/100 or 0.55. This means that 55% is 0.55(180) = 99. So using the given information this means that 99 pints is pure fruit juice in the mixture. This comes from mixing the first two brands, so that means if we take the pure fruit juice from the first brand and add it to the second brand we get 99, and remember we are given the information that 45% of the first brand is pure fruit juice and the second is 95%, this means that 0.45x is pure fruit juice in the first brand and 0.95y is pure fruit juice in the second brand. This sets up the following equation: [tex]99 = 0.45x + 0.95y[/tex]
The second equation to set up is using the total amount of pints. x represents how much is from the first brand, and y represents how much is from the second brand. Since the mixture consists of these two brands, and the mixture is 180 pints we can form the equation: [tex]180 = x+y[/tex]
The last step is to solve the systems of equations using the two equations we formed. This can be done via substitution. We simply need to solve for either x or y, in the total amount of pints equation and then substitute it into the pure fruit juice equation. In this example I'll solve for x
Original Equation:
[tex]180 = x+y[/tex]
Subtract y from both sides
[tex]180-y=x[/tex]
So now that we solved for y in terms of x we can substitute this into the pure fruit juice equation, so that we're only dealing with one variable.
Original Equation:
[tex]99 = 0.45x + 0.95y[/tex]
Substitute 180-y as x
[tex]99 = 0.45(180-y) + 0.95y[/tex]
Distribute the 0.45
[tex]99=81-0.45y+0.95y[/tex]
Add like terms
[tex]99=81+0.5y[/tex]
subtract 81 from both sides
[tex]18=0.5y[/tex]
Divide both sides by 0.5 (same thing as multiply by 2)
[tex]36=y[/tex]
This means we have to use 36 pints of the second brand. We can substitute this into either equation to solve for x, but it's easier to substitute into the total pints equation since there are no coefficients (technically a 1 in front, but it's kind of be ignored for now), so it's pretty straightforward to solve for x
Original Equation:
[tex]180=x+y[/tex]
Substitute 36 as y
[tex]180=x+36[/tex]
Subtract 36 from both sides
[tex]144=x[/tex]
This means 144 pints from the first brand and 36 from the second

How to solve Inequality problems?
We want to solve the inequality;
(4x² + 5x - 9)/(x² - x - 6) ≥ 0
Let us factorize both numerator and denominator to get;
4x² + 5x - 9 = (4x + 9)(x - 1)
Similarly, x² - x - 6 when factorized gives;
x² - x - 6 = (x + 2)(x - 3)
Thus, we now have;
[(4x + 9)(x - 1)]/[(x + 2)(x - 3)] ≥ 0
Multiply both sides by [(x + 2)(x - 3)] to get;
(4x + 9)(x - 1) ≥ 0

(4x + 9) ≥ 0 or (x - 1) ≥ 0

A population of a particular yeast cell develops with a constant relative growth rate of 0.4425 per hour. The initial population consists of 3.1 million cells. Find the population size (in millions of cells) after 3 hours. (Round your answer to one decimal place.)
The exponential function is often used to model the growth or decay of a population
The population size of the yeast cell after 3 hours is 6.24 million
The given parameters are:
a = 3.1M --- initial number of cells
r = 0.4425 per hour --- rate
The nth term of an exponential function is:
f(n) = a(1+r)^n-1
After 3 hours; n = 3
So, we have:
f(3) = a(1+r)^3-1
Substitute values for a and r
f(3) = 3.1 (1+0.4425)^3-1
f(3) = 3.1 ( 1.4425)^2
f(3) = 6.24
Hence, the population size of the yeast cell after 3 hours is 6.24 million.

Answer:
708π in³ = 2224.25 in.³
Step-by-step explanation:
The composite solid is made up of a cone, a cylinder, and a half sphere.
Recall the volume formulas:
cone: πr²h/3
cylinder: πr²h
sphere: 4πr³/3
half sphere: (1/2) × 4πr³/3
We need to find teh heoght of the cone. The slant height is 10 in. The radius is 6 in. We can use the Pythaogorean theorem to find the height of the cone.
h = √(10² - 6²) = 8
total volume = π(6 in.)²(8 in.)/3 + π(6 in.)²(13 in.) + (1/2) × 4π(6 in.)³/3
total volume = π(96 in.³ + 468 in.³ + 144 in.³)
total volume = 708π in³ = 2224.25 in.³
