Answer:

Step-by-step explanation:

Count pairs (a, b) whose sum of squares is N (a^2 + b^2 = N)

Given a number N, the task is to count all ‘a’ and ‘b’ that satisfy the condition a^2 + b^2 = N.

Note:- (a, b) and (b, a) are to be considered as two different pairs and (a, a) is also valid and to be considered only one time.

Examples:

Input: N = 10

Output: 2

1^2 + 3^2 = 9

3^2 + 1^2 = 9

Input: N = 8

Output: 1

2^2 + 2^2 = 8

Answer:

A. b2 – 4ac = 0

Step-by-step explanation:

Hey user☺☺

Option a is correct

Because the graph has only one solution.

As the graph touches the x-axis at one point that means that it will have only one solution for x. But we know that a quadratic equation has two solutions. So the graph will have two equal solution and therefore the discriminant will be 0.

Hope this will help☺☺

What is 5000 rounded to the nearest hundred
Vlada [557]

The next larger hundred is  5,100 .
The next smaller hundred is  4,900 .
5,000  is exactly midway between  4,900  and  5,100.
Neither of them is closer to  5,000  than the other one is.
So  5,000  is already rounded to the nearest hundred.

Identify the coordinates of the point (3,-2), translated 5 units left and 6
kap26 [50]

Answer:

(- 2, 4 )

Step-by-step explanation:

A translation of 5 units left means subtract 5 from the original x- coordinate.

A translation of 6 units up means add 6 to the original y- coordinate.

Thus

(3, - 2 ) → (3- 5, - 2 + 6 ) → (- 2, 4 )

A scientist is studying wildlife in Ohio and she estimates that the population of bats is tripling every year. If she had counte
Sloan [31]

The number of bats that there would be in 2021 would be 768,000.

<h3>What would be the number of bats in 2021?</h3>

The formula that can be used to determine the future value of bats in 2021 is:

FV = P (1 + r)^n

Where:

  • FV = Future value
  • P = Present value = 3000
  • R = interest rate = 300%
  • N = number of years = 4

3000(1 + 3)^4

3000 x 4^4 = 768,000
