Answer:
1,338,750$
Step-by-step explanation:
1990 price was 850,000
in 2000
850,000 + 125% = 1,062,500
850,000 + 1,062,500 = 1,912,500
in 2013
1,912,500 - 30% = 573,750
1,912,500 - 573,750 = 1,338,750
1. If the ratio of AB to BC is 4:9, what is the area of Parallelogram ABCD?
Answer:
not determinable
Step-by-step explanation:
you can't determine--think of it like this: let's say I figure out a combination of two lengths that work, I could always scale it up (or down)
Let's say AB = 4, and BC = 9, then the area would be 36
but let's say AB = 8, and BC = 18, then the area would be 144
so, from this information alone, we cannot find the answer
hope this helps! have a lovely day :)
The area of the given parallelogram is that: It cannot be determined from the information given
How to find the area of the parallelogram?The formula for the area of a parallelogram is:
Area = Base * Height
Now, we are told that the ratio of AB to BC is 4:9.
The most important point here is that we do not know the altitude of the parallelogram; the area of a parallelogram is altitude times base.
A secondary point would be that we do not know the lengths of AB and BC; we only know the ratio of the two sides.
The actual lengths of the sides could be, for example, 8 and 18

Step-by-step explanation:
given 2 secants drawn from an external point to the circle , then
the product of the measures of one secant's external part and that entire secant is equal to the product of the other secant's external part and that entire secant, that is
9(9 + 2 + 3x) = 10(10 + 2x + 2)
9(11 + 3x) = 10(12 + 2x) ← distribute parenthesis on both sides
99 + 27x = 120 + 20x ( subtract 20x from both sides )
99 + 7x = 120 ( subtract 99 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3
Answer:
(A). 3
Step-by-step explanation:
[ 9 + ( 2 + 3x )] × 9 = [ 10 + ( 2x + 2 )] × 10
27x + 99 = 20x + 120
7x = 21

What is an exponential function?An exponential function is a mathematical function of the following form: f ( x ) = [tex]p^{x}[/tex] where x is a variable, and p is a constant called the base of the function. The most commonly encountered exponential function base is the transcendental number e.
Analysis:
If for every value of x being positive and y is a positive whole number and for every x being negative y is a positive fraction, then that exponential function has a whole number base, Other wise it would have a fractional base. From the above explanation, f has (1,3) (positive x and whole number y) and (-1, 1/3) (negative x and positive fraction y). so therefore f has a whole number base and g has a fraction base.
Therefore f(x) = [tex]3^{x}[/tex] and g(x) = [tex](\frac{1}{3} )^{x}[/tex]

Write the slope-intercept form of the equation of the line described.
1) through: (3, 0), parallel to y=2/3 x + 1
2) through: (4, 1), parallel to y= -1/2 x + 2
Answer:
1) y = 2/3x - 2
2) y = -1/2x + 3
Step-by-step explanation:
1) Parallel lines have the same slopes. Write it in standard form (y = mx + c), then substitute the values of the coordinates into the equation.
y = 2/3x + c
0 = 2/3(3) + c
0 = 2 + c
0 - 2 = c
- 2 = c
Therefore, the slope-intercept form for the first part is y = 2/3x - 2.
2) Parallel lines have the same slopes. Write it in standard form (y = mx + c), then substitute the values of the coordinates into the equation.
y = -1/2x + c
1 = -1/2(4) + c
1 = -2 + c
1 + 2 = c
3 = c
Therefore, the slope-intercept form for the second part is y = -1/2x + 3.

We'll assume that there is an equal probability of any position on the wheel, so a [tex]\frac{1}{37}[/tex] chance for any given number.
We must take the probability of getting a 27, then the probability of getting a 15, and multiply them together to find the chances that they both happen in a row.

Use the Law of Cosines to find the specified missing value. Approximate your answer to the nearest tenth.
If A = 60°, b = 20 ft, c = 30 ft, find B.
Answer:
40.9
Step-by-step explanation:
Law Of Cosines:
[tex]cos(A)=\frac{b^2+c^2-a^2}{2bc}[/tex]
This can generally be understand as the cosine(angle) = the sum of squares of the two other sides - the opposite side squares divided by 2 times the other two sides
If this is to confusing to understand I'll just provide the formula for the other two angles which is essentially the same thing just different variables
[tex]cos(B)=\frac{a^2+c^2-b^2}{2ac}\\\\cos(C)=\frac{a^2+b^2-c^2}{2ab}[/tex]
Anyways for the law of cosines we need all three sides, but since we're given the two other sides, we can also rearrange the equation to solve for the other missing side.
Original Equation
[tex]cos(A)=\frac{b^2+c^2-a^2}{2bc}\\[/tex]
Multiply both sides by 2bc
[tex]cos(A)*2bc=b^2+c^2-a^2[/tex]
Add a^2 to both sides
[tex]cos(A)*2bc+a^2=b^2+c^2[/tex]
Subtract 2bc * cosA from both sides
[tex]a^2=b^2+c^2-2bc*cos(A)[/tex]
So this can be applied for any side, and it can be generally seen as: side ^2 = sum of squares of other two sides - 2 times the other two sides * cos(opposite angle of the original side). If that's to confusing you can also just look at the other formulas which are essentially the same just different variables
[tex]b^2=a^2+c^2-2ac * cos(B)\\c^2=a^2+b^2-2ab*cos(C)[/tex]
anyways, applying this formula we get the equation:
[tex]a^2=20^2+30^2-2(20)(30)*cos(60)[/tex]
Square and multiply values you get
[tex]a^2=400+900-1200*cos(60)[/tex]
Now add the values and you can calculator cos(60) using a calculator or using the unit circle, both should give the same value
[tex]a^2=1300-1200(0.5)[/tex]
Multiply
[tex]a^2=1300-600[/tex]
Simplify
[tex]a^2=700[/tex]
Take the square root of both sides
[tex]a\approx 26.4575[/tex]
So now use this to solve for B using the original law of cosines equation. Plugging in all the sides you get the equation:
[tex]cos(B)=\frac{26.4575^2+30^2-20^2}{2(26.4575)(30)}[/tex]
Square values and simplify denominator
[tex]cos(B)=\frac{700+900-400}{1,587.451}[/tex]
Simplify numerator
[tex]cos(B)=\frac{1200}{1,587.451}[/tex]
Convert to decimal
[tex]cos(B)\approx 0.755[/tex]
Take the inverse cosine of both sides
[tex]B \approx cos^{-1}(0.755)[/tex]
Approximate this using a calculator
[tex]B\approx 40.8934[/tex]
Round to the nearest tenth
[tex]B\approx40.9[/tex]

Given a decile cut point value of 10.4, where the tenth sequential value is 32 and the eleventh value is 42, what is the actual decile value
The actual decile value is 126.6
To get the actual decile value, the decile formula is used. The formula used is:
Di = I (n+1) / 10 multiplied by (n - n+1)/10
This implies that the decreased fee, which in this case is 32 + 1, is delivered to the entire multiplication of the cut point 10.4, and the difference among the more tremendous value whilst organized in the ascending fee and the newly brought decreased value.

In a small town in the Himalayas, the average snowfall each month is 6 inches. July is the month with the lowest average snowfall, of 1 inch. Construct a function that models this behavior. During what period is there more than 10 inches of snowfall?
The function that models the above behavior is given as:
f(x) = ACos(B(x + C)) + 6 ..... .......i
where x = 1 (that is January)
D (Average Snowfall) = 6.
Hence, the amplitude (A) is given as:
A = 6-1
= 5
What is a mathematical function?A mathematical function is a function comprising of different variables that represent different factors or events and the relationships between them.
Recall that in a year we have 12 months. Hence, P = 12
→ P = (2π) /.B → (2π)/B = 12 → B = π/6
Taking the values of A and B and plugging them in, we ahve:
F(x) = 5 cos (π/6(x + C)) + 6................ii
This means that in July, we'll have
x = 7 and f(x) = 1
Therefore,
1 = 5cos ((π/6) (7 + C) + 6 → 5 Cos ((π/6) (7 + C) → -5cos ((π/6) (7 + C)
= -1
→ ((π/6) (7 + C) = π
→ 7 + C = 6
→ C = -1
Taking equation ii, we have
F(x) = 5cos ((π6) (x -1)) + 6
F (x) > 10
Therefore
5cos ((π/6) (x-1) + 6 > 10
→ cos ((π/6) (x-1) + 6 > 4/5
→ (π/6) (x-1) > Cos⁻¹ (4/5)
(π/6) (x-1) < 0.6435 and
(π/6) (x-1) > 5.6397
→ x < 2.23 and x > 11.77
The interpretation is that upwards of ten inches of snow fall in January, February, November, and December.

What is the slope or gradient?A numerical assessment of a line's angle relative to the ground is known as the slope.
Given data;
m₁ is the slope of line AB

The coordinate points are,

B,(x₂,y₂)=(3, 0).
The gradient of line AB;

The slope of the lines has a perpendicular relation is -1;
m₁ × m₂ = -1
(-2) × m₂ = -1
m₂ = 1/2
m₂ = 0.5
The equation of the line passing through point A and perpendicular to AB;
(y - y₁) = m₂(x-x₁)
(y-6)=0.5(x-0)
y-6 = 0.5 x
y-0.5x=6
