A certain forest covers an area of 2,000 square kilometers. Suppose that each year this area, decreases by 6%. What is the equation that best represents the area of the forest each year?
Hint: Use the formula y = P(1 + r)x.
y = 2,000(0.94)x
y = 2,000(1.06)x
y = 2,000(0.06)x
y = 2,000(1.94)x
Answer:
y = 2,000(0.94)x
Step-by-step explanation:
f(x) = P (1 + r) ^x
P = 2000
r = -0.06
f(x) = 2000 (1 - 0.06)^x
= 2000 (0.94)^x
Use a calculator to solve for θ in the given interval. Cot θ= 0.7615, for 0 < θ < 2 pi
θ = 52.71° or 232.71°
In radians
θ = 0.2928π rad or 1.2928π rad
That is,
θ = 0.92 rad or 4.06 rad
Step-by-step explanation:
Cot θ = 0.7615 for 0 ≤ θ ≤ 2π
Note that Cot θ = (1/tan θ)
(1/tan θ) = 0 7615
tan θ = (1/0.7615) = 1.3132
θ = tan⁻¹ (1.3132) = 52.71°
But, note that tan is also positive in the 3rd quadrant, hence,
θ is also equal to 180° + 52.71° = 232.71°
θ = 52.71° or 232.71°
We now convert to radians
360° = 2π
52.71° = (52.71 × 2π)/360 = 0.2928π = 0.92 radian
232.71° = (232.71 × 2π)/360 = 1.2928π = 4.06 radians
Convert 3009 inches to yards,feet and inches. (Show your work)
Answer:
Yards: 83.58
Feet: 250.75
Inches: 3009
Step-by-step explanation:
Yards: 1 yard = 36 inches
3009/36= 83.58
So if each yard is 36 inches and there are 83.58 sets of 36 inches in 3009 then that's how many yards you have.
Feet: 1 foot = 12 inches
3009/12= 250.75
Again, if each foot is 12 inches and there are 250.75 sets of 12 inches in 3009 then that's how many feet you have.
Inches: It's already in inches :)
I hope this isn't confusing and I could help!
Answer:
Yards : 83.5833333 Feet:250.75 Inches: 9

2. Solve the system by graphing or using a table.
2x + 4y= 12
X+ y = 2
(-3,7)
(-2,4)
(-4,1)
infinitely many solutions
Answer:
x = -2 and y = 4
Step-by-step explanation:
We have given a system of equations
2x + 4y =12 ...........(1)
and
x + y = 2 .............(2)
Now to plot them in graph we need to find the points of the above linear equations .
From equation 1 ,we get
4y=12-2x
[tex]y=\frac{12-2x}{4} \\y=3-\frac{x}{2} \\[/tex]
Put x=0, then
[tex]y=3-\frac{0}{2} =3\\[/tex]
Put x=6
[tex]y=3-\frac{6}{2}=3-3=0[/tex]
So get the points (0,3) and (6,0).
From equation 2 ,we get
y=2-x
put x=0
y=2-0=2
put x=2
y=2-2=0
So we get the points (0,2) and (2,0).
So after plotting these points we get two lines intersecting at (-2,4).
Therefore our solution is x=-2 and y= 4.
write equation in slope intercept form(7,4) and (-5,-4)

Classify the triangle. Find the value of x
Answer:
x= 9
Step-by-step explanation:
<2 + 40 + 40 = 180 degree
<2 = 180 - 40 - 40
<2 = 100
m<2 = x + 109
x = 109 - <2 = 109 - 100 = 9

Area of ∆ABC = 36,Area of ∆PQR = 64AB = 12
Area of ∆ABC = 36,Area of ∆PQR = 64AB = 12The correspondence ABC ↔ PQR is a similarity.
Area of ∆ABC = 36,Area of ∆PQR = 64AB = 12The correspondence ABC ↔ PQR is a similarity.To find: PQ = ?
Area of ∆ABC = 36,Area of ∆PQR = 64AB = 12The correspondence ABC ↔ PQR is a similarity.To find: PQ = ?For this,
Recall the property,
Ratio of areas of two similar triangles = Ratio of squares of the corresponding sides
Area of ∆PQR / Area of ∆ABC =(PQ/AB)²
64 /36 = (PQ/AB)²
(PQ/AB) = √64 /36
(PQ/AB)= 8/6
PQ=AB ×8/6
PQ = 12×8/6
⇒ PQ = 2 × 8
⇒ PQ = 2 × 8⇒ PQ = 16
⇒ PQ = 2 × 8⇒ PQ = 16Thus, answer is 16.

The circumradius of a cyclic polygon is a radius of the circle inside which the polygon can be inscribed. The height can sometimes be such radius but this should be proved from the equation height of a triangle equation
isosceles not using Pythagoras = hᵇ = √ (a² - (0.5
isosceles using Pythagoras= h = 2 * area / b
obtuse height formula =Area of an obtuse-angled triangle = 1/2 × base × height. Therefore, the height of the obtuse triangle can be calculated by: Height = (2 × Area)/base Substituting the values, we get:.
So as we know Given a=3 and c=8, shows a higher amount for 7 but stays 7 in all circumstances of 1significant figure just like 8 stayed rounded down when using round figure just 7. We get;
b = 7.4162
∠α = 22.024° = 22°1'28" = 0.3844 rad
∠β = 67.976° = 67°58'32" = 1.1864 rad
h = 2.78107
area = 11.1243
perimeter = 18.4162
inradius = 1.2081
circumradius = 4
When the circumradius is 4 and we need the ratio to the inradius
this means the ratio is R : r as;
3/4 :7/4 : 8/4 = 18/4 / 7/2 = 9/7 which shows us the cr radius to the in radius ratio.
R:r therefore = 9/7

Step-by-step explanation:
The incentre is equally far away from the triangle's 3 sides , then
MA = LA , that is
6x - 3 = 5x - 1 ( subtract 5x from both sides )
x - 3 = - 1 ( add 3 to both sides )
x = 2
Then
LA = 5x - 1 = 5(2) - 1 = 10 - 1 = 9 , so
NA = LA = 9 units

Calculate 0.35+4/5+37/100 leaving your answer as a decimal
Answer:
1.52
Step-by-step explanation:
You can convert all the numbers into a fraction to solve the expression.
4/5 is equal to 80/100, and 0.35 is equal to 35/100. (37/100 is left as it is.)
80/100 + 35/100 + 37/100 = 152/100.
When simplified and converted into a decimal, the answer is 1.52.
Warren runs races to support local charities. In April, he ran a 5-kilometer race in 30 minutes to support his local hospital. In October, he will run a 10-kilometer race to support the animal shelter. If he runs at the same rate, how many minutes will it take Warren to run the race in October?
Warren ran 10 km in 60 minutes or 1 hour.
What is proportionality?Proportionality is a case when two ratios are equal.
Given that Warren runs for charity, so, he runs for a hospital a 5-kilometer race in 30 minutes, on the same rate he ran a 10-kilometer race to support the animal shelter.
We need to find the time taken by him when he ran 10 km race.
Since, the rate of running is same, that means the speed was equal in both races,
Let t be the required time,
Therefore, using the concept of proportionality,
5 / 30 = 10 / t
5t = 300
t = 60
Therefore, he ran 10 km in 60 minutes or 1 hour.

Which equation Best represents the line grafted above
The answer choices are in the photo
Answer: y=x+4
Step-by-step explanation:
The equation for a straight line can be written as y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).
We can determine b just by looking at the value of y at x=0, which is y=4.
This quickly gives us y = mx + 4. This immediately eliminates two of the possible answers (the ones where b = -4).
All we need to do now is find the slope, m.
The slope of the line can be determined by calculating the "Rise/Run." That is the change in y (Rise) for each change in x (Run). Pick any two points. I'll choose (-2,2) and (2,6). Rise = (6-2)=4; Run = (2 - (-2)) = 4.
The Rise over the Run is 4/4, or 1. The graphed line has a slope of 1, so we can now write:
y = 1x + 4
Test this by entering any vlaue of x and see if this equation correctly returns tha same value as shown on the graph. E.g., when x = 6, will this equation correctly predict y as 10? It does, so let's go with y=x+4.
