Mathematics

Firlakuza [10]2 years ago

Answer:

distance = 10.8

Step-by-step explanation:

the distance between 2 points is the Hypotenuse of the right angled triangle of the x and y coordinate differences.

so, Pythagoras is used.

c² = a² + b²

c = the Hypotenuse (the side of the triangle being opposite to the 90 degree angle).

x- difference : -4 - -8 = +4

y- difference : -3 - 7 = -10

c² = +4² + (-10)² = 16 + 100 = 116

c = sqrt(116) = 10.8

1 5/6 divided by 2 1/8 by writing it out to solve the problem. STEP BY STEP
Artist 52 [7]
1 5/6 divided by 2 1/8
1) you must change the mixed numbers into improper fractions
2) 1 5/6 is 11/6 and 2 1/8 is 17/8
3) then you must change the operation from division to multiplication
4) then you have to find the recipricol of 17/8 (flip it) and it will be 8/17
5) Finally, you multiply and you will get 88/102: 11/6x8/17=88/102 amd yoy can simplify if asked

The sum of three consecutive terms of an arithmetic sequence is 27, and the sum of their squares is 293. What is the absolute di
Ber [7]

The absolute difference between the greatest and the least of these three numbers in the arithmetic sequence is 10.

The sequence is an arithmetic sequence. Therefore,

d = common difference

let

a = centre term

Therefore, the 3 consecutive term will be as follows

a - d,  a, a + d

a - d +  a + a + d = 27

3a = 27

a = 27 / 3

a = 9

Therefore,

(a-d)² + (a)² + (a + d)² = 293

(a²-2ad+d²) + 9² + (a² + 2ad + d²) = 293

(81 - 18d + d²) + 81 + (81 + 18d + d²) = 293

243 + 2d² = 293

2d² = 50

d² = 50 / 2

d = √25

d = 5

common difference = 5

Therefore, the 3 numbers are as follows

9 - 5 , 9, 9 + 5 = 4, 9, 14

The difference between the greatest and the least of these 3 numbers are as follows:

14 - 4 = 10
