What is Exponential function?

Calculating the exponential growth or decay of a given collection of data is done using an exponential function, which is a mathematical function. Exponential functions, for instance, can be used to estimate population changes, loan interest rates, bacterial growth, radioactive decay, and disease spread.

The standardform of exponential form is

f(x) = a^x

1. y = 1^x

Thus is not Exponential function because any power of 1 result to only 1.

2. y = 1/2^x

This is Exponential Function as it has initial value 0.5.

3. y = -2^x

This is Exponential Function as it has initial value -2.

Which equation represents a circle with a center at (–4, 9) and a diameter of 10 units?(x – 9)2 + (y + 4)2 = 25
(x + 4)2 + (y – 9)2 = 25
(x – 9)2 + (y + 4)2 = 100
(x + 4)2 + (y – 9)2 = 100

Answers

The equation for this circle is given as

(x+4)^2 + (y-9)^2 = 25

Data

  • h = -4
  • k = 9
  • r = diameter/2 = 10/2 = 5

Equation of Circle

The equation of circle is given by

(x-h)^2 + (y-k)^2 = r^2

Let's substitute our values and get our equation

(x--4)^2 + (y-9)^2 = 5^2\n(x+4)^2 + (y-9)^2 = 25

we substituted the values of h and k and made sure it's in the standard form of equation of a circle.

The equation for this circle is given as

(x+4)^2 + (y-9)^2 = 25

This looks exactly like

(x-h)^2 + (y-k)^2 = r^2

Answer:

(x + 4)^2 + (y – 9)^2 = 25

Step-by-step explanation:

The standard form for a circle is

(x - h)^(2) + (y - k)^(2) = r^(2)     where (h, k) is the center and r is the radius

In your case, h = -4 and k = 9 and r = 5

So, (x + 4)^2 + (y – 9)^2 = 25

What shapes will have diagonals that are not lines of symmetry

Answers

When a mirror is placed along the diagonal of a rectangle, the result does not look the same as the original rectangle, so the diagonal is not a line of symmetry. This new shape --- the combination of the triangular half of the original rectangle and its image in the mirror --- is called a kite.
