Step-by-step explanation:

Let there be point X whose coordinates are (a2,b2) and point Y whose coordinates are (a1,b1)

Using distance formula ,

\sqrt{ ({a}^{2} -  {a}^{1}) + ( {b}^{2} -  {b}^{1}  )  }

where \:  {a}^{2 }  >  {a}^{1}   \: and \: \:   {b}^{2}  >  {b}^{1}

If \:  {a}^{1} > {a}^{2} \: and \: {b}^{1}>{b}^{2}

Distance formula will be

\sqrt{({a}^{1} - {a}^{2}) + ({b}^{1} - {b}^{2})}

Dorian buys 2 pounds of almonds for $21.98 and 3 pounds of dried apricots for $26.25. Which is less expensive per pound? How muc
ozzi

Answer:

The apricots are less expensive per pound.

Step-by-step explanation:

Cost of 1 pound of almonds = 21.98/2

Cost of 2 pounds of almonds = $21.98

So then you have to do 21.98 - 21.98/2. Which equals $10.99

Cost of 1 pound of dried apricots = 26.25/3

Cost of 3 pounds of dried apricots = $26.25

So then you have to do $26.25 - 26.25/3 which = $17.5 then divide that by 2 which equals $8.75.

To find out how much less expensive you have to find the difference, so to do that you have to do $10.99 - $8.75 = $2.24 per pound less expensive.

If a security pays $55 in one year and $133 in three years, its present value is $150 if the interest rate is
Evgesh-ka [11]

Answer:

10%

Step-by-step explanation:

What we will do is apply the present value formula that would be as follows:

PV = P1 / (1 + R) + P2 / (1 + R) ^ 2 + ... + Pn / (1 + R) ^ n

Where VP is the present value, P would be the payment in each corresponding year and R what we are looking for, the interest rate.

Replacing we have the following values:

150 = 55 / (1 + R) + 133 / (1 + R) ³

We have a cubic equation that here is very complex to answer so we are going to use the symbolab tool.

Next we can see how it calculates the value of R step by step.

https://es.symbolab.com/solver/step-by-step/150%20%3D%2055%20%2F%20%5Cleft(1%20%2B%20R%5Cright)%20%2B%20133%20%2F%20%5Cleft(1%20%2B%20R%5Cright)%20%C2%B3

The result is that R equals approximately 0.09976, therefore the interest rate is 9.976%, or rounding 10%
