Answer:

the value of the home after 12 years =$275,165.60

Step-by-step explanation:

To find value of appreciation after 12 years

We apply exponential growth formula

[tex]y=a(1+r)^x[/tex]

Where a represents the initial amount (purchased amount)

a= 182,100

r = rate of interest ( appreciation percentage) = 3.5% = 0.035

x  represents the time period= 12 years

Plug in all the values

[tex]y=a(1+r)^x[/tex]

[tex]y=182100(1+0.035)^12[/tex]

y= 275165.6025027724  

y=$275165.60

a. The percentage of students who prefer strawberries is 33.33%.

b. The percentage of students who prefer the least favorite fruit is 8.33%.

c. The percentage of students who prefer apples or pears is 45.83%.

A) To find the percentage of students who prefer strawberries:

Add up the total number of students surveyed: 30 (apples) + 15 (oranges) + 40 (strawberries) + 25 (pears) + 10 (peaches) = 120 students.

Determine the number of students who prefer strawberries: 40.

Calculate the percentage: (Number of students who prefer strawberries / Total number of students surveyed) * 100 = (40 / 120) * 100 = 33.33%.

B) To find the percentage of students who prefer the least favorite fruit:

Identify the least favorite fruit, which is peaches with 10 preferences.

Calculate the percentage: (Number of students who prefer peaches / Total number of students surveyed) * 100 = (10 / 120) * 100 = 8.33%.

C) To find the percentage of students who prefer apples or pears:

Add up the number of students who prefer apples and pears: 30 (apples) + 25 (pears) = 55.

Calculate the percentage: (Number of students who prefer apples or pears / Total number of students surveyed) * 100 = (55 / 120) * 100 = 45.83%.

So, the answers are:

A) 33.33%

B) 8.33%

C) 45.83%

The detailed answer provides percentages for students preferring specific fruits from a survey.

A) What percent of students surveyed prefer strawberries?

By definition, BF = 1/2 * CE;

So, BF = 1/2 * 90 = 45.

BF = 45

(Midsegment Length Theorem)

Answer:

BF=45

Step-by-step explanation:

Here the given point B and point [tex]F[/tex] are the midpoint of the sides AC and AE respectively in triangle ACE .

According to converse of Thales theorem -if a line divides any two sides of a triangle in equal parts then that line will be parallel to the third side of the triangle.

Also ,

In the above said condition, that line will be half of the third side

On applying this concept in the given triangle ACE

Answer:

First man rate is 115

Second man rate is 50

Step-by-step explanation:

Let's assume rate of charge of first men is x

rate of charge of second  men is y

we are given

the sum of the two rates was 165. per hour

so, we get

[tex]x+y=165[/tex]

Two men worked on a car. the first man worked 20 hours and the second man worked 15 hours. Together they charged 3050

so, we get

[tex]20x+15y=3050[/tex]

we can simplify it

[tex]5(4x+3y)=3050[/tex]

[tex](4x+3y)=610[/tex]

so, we got system of equations as

[tex]x+y=165[/tex]

[tex]4x+3y=610[/tex]

We can solve for y from first equation and plug into second equation

[tex]y=165-x[/tex]

[tex]4x+3(165-x)=610[/tex]

[tex]x+495=610[/tex]

[tex]x=115[/tex]

now, we can solve for y

[tex]y=165-115[/tex]

[tex]y=50[/tex]

Answer:

The equation of the line is y=-x

Step-by-step explanation:

To find the equation for a line, we need to know 2 points.

One of the points is (0,0) because it goes through the origin.  Another point is (5,-5).  We can calculate the slope because we have 2 points using the formula.

m = (y2-y1)/(m2-m1)

m = (-5-0)/(5-0)

m = -5/5

m=-1

The slope is -1

We know the y intercept (where it crosses the y axis) is 0.  Using the slope intercept form of a line

y = mx+b

y =-1x+ 0

y = -x

The equation of the line is y=-x

f(x) + n - move the graph n units up

f(x) - n - move the graph n units down

f(x + n) - move the graph n units to the left

f(x - n) - move the graph n units to the right

---------------------------------------------------------------------------------------

[tex]f(x)=-\dfrac{1}{5}x^2\\\\f(x+5)=-\dfrac{1}{5}(x+5)^2\\\\f(x+5)+2=-\dfrac{1}{5}(x+5)^2+2[/tex]

The equation y = -1/5 (x + 5)^2 + 2 is translated from the standard position by moving up and to the left.

In the equation y = -1/5 (x + 5)^2 + 2, the transformation of the graph from its standard position is determined by the constants within the equation. The -5 inside the parentheses causes a shift to the left by 5 units and +2 outside the parentheses represents an upward shift by 2 units. Therefore, the graph of the equation is moved up and to the left from its standard position where the vertex is at the origin.

Answer:

522

Step-by-step explanation:

We are given that the price of the motorcycle is 3238 and if we borrow it then the payment per month will be 165 for 24 months.

So the total amount that we are going to pay if we borrow the motorcycle will be 165 × 24  = 3960

While the actual price of the bike is 3438.

Difference in the payment and actual price = 3960 - 3438 = 522

Therefore, you can save 522 by paying cash.

Answer:

(a) [tex]\left\{\begin{array}{l}0.8m=2\\p+0.2m=3\end{array}\right.[/tex]

(b) correct choice is 2.5 lb peanuts and 2.5 lb mixture (2.5, 2.5);

Step-by-step explanation:

Let p represent the number of pounds of peanuts needed to make the new mixture, and let m represent the number of pounds of the 80% almond-20% peanut mixture.

1. In m pounds of the 80% almond-20% peanut mixture there are 0.8m pounds of almonds and 0.2m pounds of peanuts.

2. When added p pounds of peanuts to m pounds of mixture, you get (p+0.2m) pounds of peanuts and 0.8m pounds of almonds.

3. In 5 pounds of the 40% almond-60% peanut mixture there are [tex]0.6\cdot 5=3[/tex] pounds of peanut and [tex]0.4\cdot 5=2[/tex] pounds of almonds.

(a) Then you get a system of two equations:

[tex]\left\{\begin{array}{l}0.8m=2\\p+0.2m=3\end{array}\right.[/tex]

(b) Solve this system. From the first equation

[tex]m=\dfrac{2}{0.8}=2.5\ pounds,[/tex]

then

[tex]p+0.2\cdot 2.5=3,\\ \\p=3-0.5,\\ \\p=2.5\ pounds.[/tex]

The equation y = 5(6.8)x represents an exponential growth relationship, where an increase in the variable 'x' leads to a proportional increase in the dependent variable 'y'.

The equation y = 5(6.8)x is an expression of exponential growth, not decay. In this type of equation, known as an exponential relationship, a change in the independent variable x produces a proportional change in the dependent variable y. The factor 6.8>1 which means as x increases, y increases at a faster rate, indicating growth.

For example, this form of equation is often used to describe population growth such as bacteria under ideal conditions. Each generation of bacteria reproduces, increasing the growth rate as the bacteria population rises. This growth-based relationship can be visualized using a graph where the growth rate would be represented as a rising curve.

Answer:

h = 1558.8

Step-by-step explanation:

Let x be the distance from the vertex of the 30 degree angle to the base of Blue mountain.

Tan (30) = h/x                       Multiply both sides by x.

x * Tan(30) = h

Tan(25) = h/(x + 200)           Multiply x + 200 on both sides.

(x + 200) * Tan(25) = h

Now you have 2 equations both equal to h. The two sides can be equated to each other.

x*tan(30)  = (x + h) * Tan(25)         Divide both sides by tan(25)

x*tan(30)/tan(25) = x + 200          Find Tan(30)/Tan(25)

Tan30 / tan(25) = 1.23813 so

1.23813 x = x  + 200                      Subtract x from both sides.

0.23813x = 200                             Divide both sides by 0.23813

x = 200/0.23813

x = 839.99

================

That is not the answer you have been asked for. What you need is h.

Tan(30) = x / h                                Multiply both sides by h

h*tan(30) = x                                   Divide both sides by tan(30)

h = x/tan(30)

h = 839.99/tan(30)                        Tan 30 = 0.57735

h = 839.99/0.57735

h = 1558.8

Answer:

x = 55

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

the sum of the 4 angles in a quadrilateral = 360°

the angles to the left and above 130° angle = 50°

Since 130° and 50° form a straight angle and are supplementary

the third angle in the left triangle = 180° - (50 + 30)° = 100°

thus the angle to the right = 180° - 100° = 80°  ( straight angle )

the third angle in the upper triangle = 180° - (50 + 45)° = 85°

the angle below it = 180° - 85° = 95° ( straight angle )

We now have 3 angles inside the quadrilateral of 130°, 80° and 95°

x = 360° - (130 + 80 + 95)° = 55

Step-by-step explanation:

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x-term.

product = 3 × 5 = 15 and sum = - 8

The factors are - 3 and - 5

use these factors to split the middle term

3x² - 3x - 5x + 5 ( factor the first/second and third/fourth terms )

= 3x(x - 1) - 5(x - 1) ( take out the common factor (x - 1) )

= (x - 1)(3x - 5)

Step-by-step explanation:

x³ + 8 ← is a sum of cubes, which factors in general as

• a³ + b³ = (a + b)(a² - ab + b²)

x³ = (x)³ ⇒ a = x and 8 = 2³ ⇒ b = 2

x³ + 8 = (x + 2)(x² - 2x + 4) ← in factored form

Answer:

[tex]x^{3} +8=(x+2)(x^{2} -2x+4)[/tex]

Step-by-step explanation:

The binomial can be factored by the binomial form by trinomial. This binomial is a sum of cubes, whose general form presents the following result.

[tex](x^{3} +y^{3} )=(x+y)(x^{2} -xy+y^{2} )[/tex]

Substituting the values ​​of x and y we will have

[tex]x^{3} =x^{3} ;     y^{3} =8[/tex]

Obtaining the cubic roots of each variable

[tex]x=x; y=2[/tex]

So

[tex]x^{3} +8=(x+2)(x^{2} -2x+4)[/tex]
