Answer:
Step-by-step explanation:
you buy a house for $130000. it appreciates 6% per year. how much is it worth in 10 years
growth or decay?
write a function that represents the situation:
initial amount=
growth/decay rate:
Final answer:
The future value of the house will be approximately $232,810.10 in 10 years, calculated by compounding the initial value of $130,000 at an annual growth rate of 6%.
Explanation:
To calculate the future value of a house appreciating at a certain rate, we can use the compound interest formula: [tex]Future\ Value = Present\ Value \* (1 + growth/decay rate)^{number of periods[/tex]
In this scenario, the house is appreciating, which means it's increasing in value over time.
We're given that the initial amount (Present Value) is $130,000 and the growth rate is 6% per year.
The function that represents the situation is:
Future Value = $130,000 × (1 + 0.06)¹⁰
To find the value of the house in 10 years, we simply plug in the values:
Future Value = $130,000 × (1 + 0.06)¹⁰
Future Value = $130,000 × (1.06)¹⁰
Future Value = $130,000 × 1.790847
Future Value = $232,810.10 approximately
Therefore, the house will be worth approximately $232,810.10 in 10 years, and this represents growth, not decay.
which of the following is a point slope equation of a line with the point (1, 8) and a slope of -5? a. y +8=-5(x+1) b. y- 5 = -5(x-8) c. y+ 5= -5(x+8) d. y-8=-5(x-1)
Answer:
Option D. [tex]y-8=-5(x-1)[/tex]
Step-by-step explanation:
we know that
The equation of a line into point slope form is equal to
[tex]y-y1=m(x-x1)[/tex]
we have
[tex](x1,y1)=(1,8)[/tex]
[tex]m=-5[/tex]
substitute
[tex]y-8=-5(x-1)[/tex]
The correct point-slope equation for a line passing through the point (1, 8) with a slope of -5 is y - 8 = -5(x - 1).
The point-slope form of an equation of a line is y - y1 = m(x - x1), where (x1, y1) is the point on the line and m is the slope.
Given the point (1, 8) and a slope of -5, the correct point-slope equation is d. y - 8 = -5(x - 1).
Therefore, the correct answer is d. y - 8 = -5(x - 1).

x - 1 = 0
x - 1 +1 = 0 + 1
x = 1
x - 4 = 0
x - 4 + 4 =0 +4
x = 4
x + 7 = 0
x + 7 - 7 = 0 - 7
x = -7

Work out the total surface area of this hemisphere which has a radius of 8cm.
Give your answer to one decimal place
To calculate the total surface area of a hemisphere with a radius of 8 cm, we use the formula A = 3πr², resulting in a total surface area of approximately 602.9 cm² to one decimal place.
Explanation:The question asks us to work out the total surface area of a hemisphere with a radius of 8cm and provide the answer to one decimal place. The total surface area of a hemisphere is given by the formula A = 2πr² + πr², where π is approximately 3.14 and r is the radius of the hemisphere. The first part 2πr² represents the curved surface area, and the second part πr² represents the area of the circular base.
Substituting 8 cm for r:
A = 2π(8²) + π(8²) = 2π(64) + π(64) = 128π + 64π = 192π cm²
Converting π to 3.14:
A = 192(3.14) = 602.88 cm². Therefore, the total surface area of the hemisphere is approximately 602.9 cm² to one decimal place.
The total surface area of this hemisphere is approximately 603.2 cm².
Calculating the Total Surface Area of a Hemisphere
To find the total surface area of a hemisphere with a radius of 8 cm, we need to consider both the curved surface area and the base area.
Curved Surface Area: The formula for the curved surface area of a hemisphere is given by 2πr², where r is the radius. Substituting the given radius (8 cm), we get:
Curved Surface Area = 2π(8 cm)² = 2π(64 cm²) ≈ 2 × 3.1415927 × 64 = 402.1 cm² (rounded to one decimal place)
Base Area: The base of the hemisphere is a circle with the area given by the formula πr². Using the radius (8 cm), we get:
Base Area = π(8 cm)² = π(64 cm²) ≈ 3.1415927 × 64 = 201.1 cm² (rounded to one decimal place)
Total Surface Area: To find the total surface area, we sum the curved surface area and the base area:
Total Surface Area = 402.1 cm² + 201.1 cm² = 603.2 cm²
Therefore, the total surface area of the hemisphere is approximately 603.2 cm².

Find the missing factor.
8x^2 - 15x + 7 = (8x - 7)( )
Answer:
Step-by-step explanation:
(8x - 7)(
The x^2 term has to come out to 8x^2.
The 8 is already there.
So your first term in the second factor is x.
(8x - 7) ( x
Now the question is what is the sign after the x. Since the question shows +7 the only way that can happen is if both signs in the factors are the same.
Since (8x - 7) has been given to you and you need 7 to come out plus, then the sign after x must minus. Both signs must be the same.
(8x - 7)(x -
Last, what comes after the minus sign? You already have a minus 7 so you need something to multiply by 7 to get seven.
That should be a one.
(8x - 7)(x - 1)
x - 1 is you answer. I leave you to check the middle term. It is - 15

A car is traveling at 42 mph. if its tires
have a diameter of 27 inches, how fast are
the car's tres turning? Express answer
in revolutions per minute.
Answer:
522.9 revolutions /min
Step-by-step explanation:
Given Diameter, D = 27 inches
Circumference, C = πD = 3.142 x 27 = 84.82 inches
(recall 1 mi = 63360 in)
Car speed is 42 mph = 42 mph x 63,360 inches / mile = 2,661,120 inches / hr
(recall 1 hour = 60 min)
Hence car speed becomes
= 2,661,120 inches / hr ÷ 60 min/hr
= 44,352 inches / min
Number of revolutions / min
= speed in inches/min ÷ circumference
= 44,352 ÷ 84.82 = 522.9 revolutions /min
To find out how fast a tire with a diameter of 27 inches is turning for a car moving at 42 mph, you first convert miles per hour to inches per minute, then calculate the tire's circumference in inches, and divide the car's speed by this circumference. The calculated result is approximately 523.05 revolutions per minute.
Explanation:To answer this question, we first need to convert the information about speed and tire diameter to compatible units. We'll convert the car speed from miles per hour (mph) to inches per minute since the diameter of the tire is given in inches.
Since 1 mile equals 63,360 inches, 42 mph is equal to 42*63360 = 2,661,120 inches per hour. As there are 60 minutes in an hour, that comes out to 2,661,120/60 = 44,352 inches per minute.
Next, we will find the circumference of the tire, which is its diameter multiplied by pi. Therefore, we have a circumference of 27 inches * 3.14 (pi) = 84.78 inches.
Finally, to find out how many times the tire rotates in a minute, we divide the car's speed in inches per minute by the tire's circumference in inches. This means the tires are making 44,352/ 84.78 ~= 523.05 revolutions per minute.

Which transformations could have occurred to map AABC
to AA"B"C"?
a rotation and a reflection
a translation and a dilation
a reflection and a dilation
a dilation and a rotation
Answer: a dilation and a rotation
Step-by-step explanation:
A reflection is a rigid transformation that maps every point of a figure in the plane to point of image of figure, across a line of reflection .A rotation of some degrees is a rigid transformation which rotate a figure about a fixed point known as the center of rotation.A translation is a rigid transformation of a figure that moves every point of the figure a fixed distance in a particular direction.A dilation is a transformation in which a figure is enlarged or reduced with respect to a point known as the center of dilation.From the given figure it can be seen that ΔABC is reduced to ΔA"B"C" so there must be dilation.
Also, when there is rotation about point C to create ΔA"B"C".
Therefore, the transformations could have occurred to map ΔABC to ΔA"B"C" are a dilation and a rotation.
Expand the binomial (1 - 2x)^6 use Pascal’s triangle
Answer:
1 - 12x + 60x^2 - 160x^3 + 240x^4 - 192x^5 + 64x^6
Step-by-step explanation:
So we need to know the 7th line of pascals triangle so let us write it out
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
1 6 15 20 15 6 1 <----- This one
Now we know we will need coefficients of x from 0 to 6, let us call this i, and for each of these the coefficient is
(-2)^i * (1)^(6-i) * number in pascals triangle
Hence
i = 0, 1 * 1 * 1 = 1
i = 1, -2 * 1 * 6 = -12
i = 2, 4 * 1 * 15 = 60
i = 3, -8 * 1 * 20 = -160
i = 4, 16 * 1 * 15 = 240
i = 5, -32 * 1 * 6 = -192
i = 6, 64 * 1 * 1 = 64
Hence (1-2x)^6 = 1 - 12x + 60x^2 - 160x^3 + 240x^4 - 192x^5 + 64x^6
