Find the distance between (-4,-3) and (-8,7)​

Mathematics
1 answer:
wariber [46]2 years ago
8 0

Answer:

√116  (or 10.77)

Step-by-step explanation:

(refer to attached )

in this case the points given are (-4,-3) and (-8,7)

hence x1 = -4, y1 = -3, x2 = -8, y2 = 7

D = √[ (x2-x1)² + (y2-y1)²  ]

= √[ (  -8 - (-4) )² + (  7 - (-3)  )²  ]

= √[ (  -8 +4 )² + (  7 + 3  )²  ]

= √[ (  -4 )² + (  10  )²  ]

= √[ (  16 ) + (  100  )  ]

= √116

= 10.77

The difference between two positive integers is 3. If the smaller is added to the square of the larger, the sum is 87.
Komok [63]
Let x be larger integer so x-3 is the smaller
so x^2+ x-3 = 87
x^2 +x -90=0 and factor
(x-9)(x+10)=0
x=9 or x=-10 but x must be positive
so x=9 and smaller number is 6

The function f(x) = 2x + 510 represents the number of calories burned when exercising, where x is the number of hours spent exer
riadik2000 [5.3K]

Answer: 789 calories burned while combining diet with 2 hours of exercise

Step-by-step explanation:

we have that

f(x)=2x+510

g(x)=200x-125

we know that

(f+g)(x)=f(x)+g(x)

substitute

(f+g)(x)=2x+510+200x-125

(f+g)(x)=202x+385

Find (f+g)(2)

For x=2 hours

substitute

(f+g)(2)=202(2)+385

(f+g)(2)=789\ calories

therefore

The answer is

789 calories burned while combining diet with 2 hours of exercise

Using the numbers 5, 8, and 24, create a problem using no more than four operations (adding, subtracting, multiplication, divisi
Alik [6]

The given three numbers are 5,8,24.

We have to use four operations (Adding, Subtracting,multiplication, division, square, square root, cube, cube root) out of these operation to make the result an irrational number.

1. \sqrt{\frac{24}{8}} + 5=\sqrt{3}+5,\\\\2. \sqrt{\frac{24}{8}} - 5=\sqrt{3} -5 \\\\ 3.\sqrt{\frac{24 \times 5}{8}}=\sqrt{15} \\\\ 4. (5 \times 8 \times 24)^\frac{1}{3}

There are many more examples that you can write.

Keep in mind

1. Sum of Rational and irrational is always irrational.

2. Difference of rational and irrational is always irrational.

As none of the 5,8,24 is a perfect square , nor addition of any two results in a perfect square, so square root of their addition or subtraction  or multiplication results in an  irrational number.

Similarly ,apart from 8, none of 5,24 is a perfect cube.So if you add or subtract any number from 8 and take their cube root  or square root ,results in an irrational number.
