what are the solutions of the quadratic equation 4x^2-8x-12=0

The lowest is the cash price for other options, you have to pay more for a laptop and refrigerator. Then the suitable method is to save up and pay cash.

The process of making choice is by identifying the correct decision, gathering information, and assessing alternative solutions.

If someone were unable to pay cash right now then the suitable method will be

For laptop:

Rent to own payments will be

$150 each month for 12 months, then the total becomes

⇒ 150 × 12 = $1800

The installment plan will be

$100.83 each month for 12 months, then the total becomes

⇒ 100.83 × 12 = $1209.96

The cash price is $1000. So, the lowest is the cash price for other options you have to pay more.

For refrigerator:

Rent to own payments will be

$140 each month for 12 months, then the total becomes

⇒ 140 × 12 = $1680

The installment plan will be

$80.67 each month for 12 months, then the total becomes

⇒ 80.67 × 12 = $968.04

The cash price is $800. So, the lowest is the cash price for other options you have to pay more.

To find a coordinate of a vertice, we see the point that the x axis and the y axis intersect. And it's written in the form of (x;y - x axis first, y axis second)

Polygon 1 :
B vertice : (1;4)
A vertice : (1;1)
C vertice : (4;6)
D vertice : (5;3)

Polygon 2 :

P vertice : (5;5)
Q vertice : (8;6)
R vertice : (7;4)
S vertice : (7;2)

After 22 days and 8 hours (0.349×24 hours) and 22 minutes (0.376×60 minutes) and 34 seconds (0.56×60 ≈ 34), the number of daily hits reaches 1,000,000.

It is given that the website hosting the song uses the function:

[tex]\rm f(t) = 2002t^2[/tex]    to represent the number of daily hits over time, where t is time in days.

It is required to predict the day on which the number of daily hits reaches 1,000,000.

It is defined as a special type of relationship and they have a predefined domain and range according to the function.

We have a function:

[tex]\rm f(t) = 2002t^2[/tex]

When f(t) = 1,000,000 then what will be the value of 't'

Simply:

[tex]\rm 1,000,000 = 2002t^2\\\rm 499.500 = t^2\\\rm \sqrt{499.500} = t\\\rm t = 22.349\ Days[/tex]

t = 22 days and 8 hours (0.349×24 hours) and 22 minutes (0.376×60 minutes) and 34 seconds (0.56×60 ≈ 34).

Thus, after 22 days and 8 hours (0.349×24 hours) and 22 minutes (0.376×60 minutes), and 34 seconds (0.56×60 ≈ 34), the number of daily hits reaches 1,000,000.

The day on which the number of daily hits of the considered song for the specified website reaches 1,000,000 is 23rd day.

You can simply replace those variables with the value you know of them and then operate on those values to get a final value. This is the result of that expression at those values of the considered variables.

So, suppose the day is t = d (dth day from the launch of the song) on which the daily hits reaches 1,000,000.

Then, evaluating the function [tex]f(t) = 2002(t^2)[/tex] at t = d should give us 1000000

Putting it, we get:

[tex]f(d) = 1000000\\2002(d^2) = 1000000\\\\\text{Dividing both the sides by 2002}\\\\d^2 = \dfrac{1000000}{2002}\\\\d = \sqrt{\dfrac{1000000}{2002}}\approx 22.35[/tex]

So after 22th day, ie on 23rd day (as 22.35 = 22 + 0.35 which shows 23rd day is still not completed) of the launch of the song, the number of daily hits reaches 1,000,000.

Thus, the day on which the number of daily hits of the considered song for the specified website reaches 1,000,000 is 23rd day.

Step-by-step explanation:

1) The reflected function [tex]g(x)=-2(3.5)^x[/tex] is defined everywhere.

2) Initial value of g(x) or g(0) is 1

3) Value of g(1) is -7

4) Value of g(-1) is -4/7

The given function is:

[tex]y=2(3.5)^x[/tex]

We know that when a function is reflected about the x-axis,

y becomes -y while x is unchanged.

So, the reflection of [tex]y=2(3.5)^x[/tex] about x-axis is:

[tex]-y=2(3.5)^x[/tex]

[tex]y=-2(3.5)^x[/tex]

[tex]g(x)=-2(3.5)^x[/tex]

g(x) is an exponential function defined everywhere.

[tex]g(0) =-2[/tex]

[tex]g(1) =-7[/tex]

[tex]g(-1) =-\frac{4}{7}[/tex]

Therefore, 1) The reflected function [tex]g(x)=-2(3.5)^x[/tex] is defined everywhere.

2) Initial value of g(x) or g(0) is 1

3) Value of g(1) is -7

Answer:

x = 57

Step-by-step explanation:

1. Look at the expression (x + 22). It's measurement the upper side of the lines. We know that if we add up all sides, we will get a full circle, or a value of 360. We know that if I extend the blue line to the left on the upper parallel line, it would equal 180 degrees.

We can express this as x + 22 = 180. Now lets look at the bottom equation, notice that the 2x - 13 is the missing side of x + 22. So we know:

x + 22 + 2x - 13 = 180

3x + 22 - 13 = 180

3x + 9 = 180

3x = 171

x = 57

2. We can check this by plugging it into our formula. x + 22 and 2x - 13. so 57 + 22 = 79 and 2(57) - 13 = 101. Add them together: 79 + 101 = 180.

3. We know this is true because both angles combined will be to form 180 degrees. For a better understanding, view the image I sent you. 1 = 3, and 4 = 2. Opposite angles are equal. In your equation, we have 3 and 8. we KNOW that 8 = 2. And we also know that adding up 2 + 3 MUST equal 180 degrees.

Answer:

1.61 x km= y miles  

x km= y/ 1.61 miles

Step-by-step explanation:

Let x represent the distance in Kilometers  and y represent the distance in miles then

1.61 x km= y miles

Now if we have 5 miles then

1.61(5) km = 5miles

8.05 km = 5 miles

Similarly if we want to express 1 km in miles the equation would be

x km= y/ 1.61 miles

So for 5 km the miles would be

5 km = 5/1.61 miles

5 km = 3.1055 miles

Answer:

MP ⊥ LO ⇒ proved

Step-by-step explanation:

In the given figure

∵ m∠LPM = m∠MNO ⇒ given

∵ m∠MNO = m∠MPO ⇒ given

→ If the measure of an angle equals the measures of another two

   angles, then the two angles must be equal in measures

∴ m∠LPM = m∠MPO ⇒ proved

∵ P ∈ line LO

∵ ∠ LPM and ∠MPO are adjacent angles

∴ ∠LPM and ∠MPO formed a pair of linear angles

→ The measure of the linear pair angles is 180°

∴ m∠LPM + m∠MPO = 180°

∵ m∠LPM = m∠MPO

→ That means the measure of each one is 180° divided by 2

∴ m∠LPM = m∠MPO = 180° ÷ 2

∴ m∠LPM = m∠MPO = 90°

∵ MP intersect LO at P and formed right angles at P

→ That means MP is perpendicular to LO

∴ MP ⊥ LO ⇒ proved

Answer:

Jose would have accumulated $23,325.21

Step-by-step explanation:

Giving the following information:

The interest rates are not clear. If they are not correct, replace them in the formulas.

Jose:

Initial investment= $8,000

Interest rate= 7.38 compounded daily.

Adam:

Initial investment= $8,000

Interest rate= 7.78% compounded annually.

Future value= 8,000*3= 24,000

First, we need to calculate the time required for Adam to triple its investment.

n= ln(FV/PV) / ln(1+i)

n= ln(24,000/8,000) / ln(1.0778)

n= 14.66 years

It will take Adam 14.66 years to triple the investment.

Now, the future value for Jose:

FV= PV*(1+i)^n

PV= 8,000

i= 0.0738/365= 0.0002

n= 14.66*365= 5,351 days

FV= 8,000*(1.0002^5,351)

FV= $23,325.21

Jose would have accumulated $23,325.21

In this case, it's 7. If it's a number greater than 5 or 5, you must round off to the next value and if it is less than 5 or 5.

Since it is 7 in the third decimal place, the answer would be 34.47
