Answer:

Peter Jonathan Winston (March 18, 1958 – disappeared January 26, 1978) was an American chess player from New York City

Step-by-step explanation:

In late 1977, Winston attended a FIDE-rated tournament at Hunter College High School in New York City. Despite being one of the highest-rated players in the tournament, Winston lost all nine of his games. A few months later, on January 26, 1978, following further surprising game losses, Peter Winston vanished and was never heard from again. According to some sources, Winston's disappearance occurred when he left his home without money, identification, or luggage during a severe winter storm. Many chess players who were close to or acquainted with Winston claim that the champion chess player's mental health had deteriorated, along with his game performance, in the last few years of his life, and that the decline in his mental health may have led to his disappearance.

There are two mystery numbers. The sum of 2 times the first number and 3 times the second number is -18. The sum of 3 times the

FrozenT [24]

Answer:

-3 and -4

Step-by-step explanation:

x = 1st number

y = 2nd number

set up system of equations:

2x + 3y = -18

3x + 2y = -17

elimination method: multiply 1st equation by -2 and second by 3

-4x - 6y = 36

5x = -15

x = -3

find y: 2(-3) + 3y = -18

-6 + 3y = -18

3y = -12

y = -4

determine the amount of an investment if $250 is invested at an interest rate of 10.3% for 40 years. Round to the rearest penny

Mariana [72]

Answer:

Final answer is $1280.

Step-by-step explanation:

Given that $250 is invested at an interest rate of 10.3% for 40 years.

Now we need to determine the amount of that investment after 40 years.

It doesn't say anything about compounding period so I will consider that as simple interest.

Hence let's use simple interest formula:

$A=P(1+RT)$

Where amount invested = P = 250

rate of interest = R = 10.3% = 0.103

Time = T = 40 years

Now plug these values into above formula

$A=250(1+0.103*40)=250(1+4.12)=250(5.12)=1280$

Hence final answer is $1280.

Item 13 Find the distance between the points C(−6, 5) and D(−3, 1). The distance between the two points is

Len [333]

Answer:

5 units

Step-by-step explanation:

Given:-

- The two points C and D are given:

C ( -6 , 5 ) & D ( -3 , 1 )

Find:-

The distance between the two points

Solution:-

- The distance (d) between two arbitrary points ( x1 , y1 ) & ( x2, y2 ) in a cartesian coordinate system is given by the following formula:

$d = \sqrt{( x_1 - x_2)^2 + ( y_1 - y_2 )^2}$

Where,

C = ( -6 , 5 ) = ( x1 , y1 )

D = ( -3 , 1 ) = ( x2 , y2 )

- Then we can calculate the distance d between the two given points:

$d = \sqrt{( -6 -(-3) )^2 + ( 5 - 1 )^2}\\\\d = \sqrt{( -3 )^2 + ( 4 )^2}\\\\d = \sqrt{9 + 16}\\\\d = \sqrt{25}\\\\d = 5 units$

- The distance between the given points C and D is d = 5 units
