A set of 3 nonzero whole numbers say (a,b,c) that form the sides of a right triangle and follow the pythagorous theorem

$a^2+b^2=c^2\\$

are called a Pythagorean Triple

The example of Pythagorean Triplet are

(3,4,5), (5,12,13) ,(8,15,17), etc.

Hence

A set of 3 nonzero whole numbers that form the sides of a right triangle are called a Pythagorean Triple.

What are the domain and range for the exponential function f(x)=ab^x , where b is a positive real number not equal to 1 and a &g

motikmotik

Answer: Domain (-∞,∞) ; range: (0,∞)

Step-by-step explanation:

1. The exponential functions with the form $f(x)=ab^{x}$ has domain of all real numbers, becaure there is no values in the set of real number for which the value of $x$ is not define. When $x$ approches to ∞, the function approches to ∞.

2. When $x$ approches to -∞, the function approches to 0 but never touches it. This means that $y$ is always greater than zero ( $y>0$ ). Therefore, the range of the function is (0,∞).

Find the center, vertices, and foci for the ellipse 25x^2+64y^2=1600

Ronch [10]

Answer:

Step-by-step explanation:

Answer:

Data

Equation 25x² + 64y² = 1600

Process

1.- Divide all the equation by 1600

25x²/1600 + 64y²/ 1600 = 1600/1600

-Simplify

x²/64 + y²/ 25 = 1

2.- Equation of a horizontal ellipse

3.- Find a, b and c

a² = 64 a = 8

b² = 25 b = 5

-Calculate c with the Pythagorean theorem

a² = b² + c²

-Solve for c

c² = a² - b²

-Substitution

c² = 8² - 5²

-Simplification

c² = 64 - 25

c² = 39

-Result

c = √13

4.- Find the center

C = (0, 0)

5.- Find the vertices

V1 = (-8, 0) V2 = (8, 0)

6.- Find the foci

F1 = (-√13, 0) F2 = (√13, 0)

Kianna and three friends went out to dinner together. The total bill was $58.49. If they each agreed to pay an equal share of th

jonny [76]

Answer: $15.00 per person.
______________________________
Explanation:
______________________________
Given that there are "4 people" (that is, "Kianna and three friends");
____________________________________________________
and a total of "$58.49" ; to be divided equally among 4 (four) people;
______________________________
we are asked to estimate the amount that EACH person will pay.
______________________________
For an ESTIMATE, $58.49 is ABOUT $60.00; or "60 dollars". ;

and (60 dollars) / 4 = 15 dollars {$15; or $15.00}.

60/4 = 15; or 60/4 = (60÷2)/(4÷2) = 30/2 = 15.

HELPP I WILL GIVE BRAINLEIST!! PLSSSSS PLSSSSSSS

musickatia [10]

Answer:

x = 3 && y = - 1

Step-by-step explanation:

Just solving the two equations

the first equation

y = 4/3 x +3

y - 4/3 x = 3 ..............................................(1)

the second equation

y = -2/3x -3

y + 2/3 x = -3 ..............................................(2)

by substracting 2 from 1

-4/3x - 2/3x = -6

divide by -1

4/3x +2/3x = 6

6/3x = 6

2x = 6

x= 3

then subsititute by value x in any of given eqautions
