com loses 1/4 of its value after every year it is purchased

v = original price times 1/4 x times(x represents)

v = 800*(3/4)^x

so, if x is five, then t is

800*(3/4)^5= 189 27/32

Answer:

[tex]v=800(0.75)^t[/tex]

$189.84 (nearest cent)

Step-by-step explanation:

If a computer loses 1/4 of its value each year, then each year it will be 75% of the value of the previous year, since 100% - 25% = 75%.  

Therefore, we need to model this as an exponential function.

General form of an exponential function: [tex]y=ab^x[/tex]

where:

From the given information:

Substituting the values into the formula:

[tex]\implies v=800(0.75)^t[/tex]

When x = 5, t = 5

[tex]\implies v=800(0.75)^5=189.84375[/tex]

⇒ v = $189.84 (nearest cent)

Answer:

[tex]\displaystyle (y + 2) = -\frac{1}{3}\, (x - 9)[/tex].

Equivalently:

[tex]\displaystyle (y - 2) = -\frac{1}{3}\, (x + 3)[/tex].

Step-by-step explanation:

Let [tex](x_{1},\, y_{1})[/tex] and [tex](x_{2}\, y_{2})[/tex] denote the coordinates of two points in the plane. If [tex]x_{1} \ne x_{2}[/tex] (i.e., the two points aren't on the same vertical line,) the slope of the line that goes through the two points would be:

[tex]\begin{aligned} m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\end{aligned}[/tex].

In this question, [tex]x_{1} = 9[/tex] and [tex]y_{1} = (-2)[/tex] (for [tex](9,\, -2)[/tex]) while [tex]x_{2} = (-3)[/tex] and [tex]y_{2} = 2[/tex] (for [tex](-3,\, 2)[/tex].) Given that [tex]x_{1} \ne x_{2}[/tex], the slope of the line that goes through these two points would be:

[tex]\begin{aligned} m &= \frac{y_{2} - y_{1}}{x_{2} - x_{1}} \\ &= \frac{2 - (-2)}{(-3) - 9} \\ &= -\frac{1}{3}\end{aligned}[/tex]

If a line in a plane is of slope [tex]m[/tex] and goes through the point [tex](x_{0},\, y_{0})[/tex], the point-slope equation of this line would be:

[tex](y - y_{0}) = m\, (x - x_{0})[/tex].

The slope of this line is [tex]m = (-1/3)[/tex]. If the point [tex](9,\, -2)[/tex] is chosen as [tex](x_{0},\, y_{0})[/tex] ([tex]x_{0} = 9[/tex] and [tex]y_{0} = (-2)[/tex],) then the point-slope equation of this line would be:

[tex](y - (-2)) = (-1/3)\, (x - 9)[/tex].

Simplify to obtain:

[tex]\displaystyle (y + 2) = -\frac{1}{3}\, (x - 9)[/tex].

Similarly, if the point [tex](-3,\, 2)[/tex] is chosen as [tex](x_{0},\, y_{0})[/tex], the point-slope equation of this would be:

[tex]\displaystyle (y - 2) = -\frac{1}{3}\, (x + 3)[/tex].

Answer:

base times height

Step-by-step explanation:

Lets say its a cube with a length of 6, a width of 6, and a height of 6. I would find the base first by multiplying the width times length, which you probably know how to do.  The base would be 36, then I would multiply it by the height which is six which would be 216.

The A option is correct.

A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

Given

The interest rate applied to the present value has on the monthly payment P in the formula

[tex]\rm P = PV(\dfrac{i}{1-i})^{-n}[/tex]

The effect an increase in i.

[tex]\rm P = PV(\dfrac{i}{1-i})^{-n}\\[/tex]

on simplifying the equation, we get

[tex]\rm P = PV(\dfrac{i}{1-i})^{-n}\\\\P = PV\dfrac{1}{(\frac{i}{1-i})^n}\\\\\\P = PV(\dfrac{1-i}{i})^{n}\\\\P = PV(\dfrac{1}{i} - 1)^{n}[/tex]

Let n be the constant, then the equation will be

[tex]\rm P = PV(\dfrac{1}{i} - 1)^{n}\\\\\dfrac{1}{V} \propto \dfrac{1}{i}\\\\V \propto i[/tex]

It is clear that V is proportional to i.

An increase in i, the interest rate, will not change P, the monthly payment.

Thus, the A option is correct.

Answer:

C. 8 is the correct answer.

Step-by-step explanation:

Let <DAB be x°

Now,

taking x as reference angle in triangle ADB,

cosx = b/h

or, cosx = 4/AB

Now,

again taking x as reference angle in triangle ACB,

cosx = b/h

or, cosx = AB/20

Now,

cosx = AB/20 = 4/AB

or, AB/20 = 4/AB

or, AB² = 80

Now,

Using pythagoras theorem in triangle ABD,

h² = p² + b²

or, AB² = BD² + AD²

or, 80 = BD² + 4²

or, 80 - 16 = BD²

so, BD² = 64

so, BD = 8

Answer:

176.625 sq.ft, 4.8 sq.ft

Step-by-step explanation:

Area of circle=πr^2 or πd^2/4
11. Given,
d=15 ft
Now,
Area=πd^2/4
3.14*15^2/4
176.625 ft^2
Therefore, the area approximation is 176.6 sq.ft
12.
Given,
d=3.5 ft
Now,
Area= πd^2/8
3.14*3.5^2/8
4.8 sq.ft
I got the answer by dividing the area of circle by 2 as semicircle is half of circle.

The variable the researchers intentionally varied in the experiment is time and the units of the variable is mins.

The independent variable is the variable that the researcher varies or changes or manipulates in the course of the experiment. The independent variable usually have a direct effect on the dependent variable.

With the passage of time, the level of concentration increases. This means that time is the independent variable and concentration is the dependent variable.

Answer:

500 lbs of mixed nuts

Step-by-step explanation:

15.4% of mixed nuts = 77 lbs of pecans

Divide the weight of pecans by the percent of mixed nuts to find how many pounds of pecans equal 1% of the mixed nuts:

77 / 15.4 = 5,  so 5 lbs equals 1% of mixed nuts

Now multiply that number by 100 to get 100% of mixed nuts:

5 x 100 = 500

Therefore, there are 500 lbs of mixed nuts in a batch altogether.

To check, 15.4% = 15.4/100 = 0.514

Therefore, 15.4% of 500 = 0.514 x 500 = 77

Thereby proving that 15.4% of 500 is 77.

Answer:

3

Step-by-step explanation:

3 is not a factor of 16.

Is that a valid answer? lol

Hi there!

First of all, let's determine the factors of 16.

Remember, a factor is a number that a number can be evenly divided by.

Example: 5 is a factor of 10, because 10 can be evenly divided by 5.

So, the factors of 16 are:

1, 2, 4, 8, and 16.

Now, there's an infinite amount of numbers that are not factors of 16. Here are some of them:

3, 5,7,9, 10,11, 12, 13, 14, 15...

Answer:

50 players

Step-by-step explanation:

Let x be the amount of players last year and y be the amount of players this year then...

y=3x+2

y=152

We can solve this using substitution. Substitute 152 for y:

y=3x+2

152=3x+2

Subtract 2 from both sides (subtraction property of equality)

152-2=3x+2-2

150=3x

Divide both sides by 3 (division property of equality)

x=50

There were 50 players last year.
