Find the radius of a circle whose area is 576π m²
k0ka [10]

Answer:

r = 24 m

Step-by-step explanation:

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Here A = 576π , then

πr² = 576π ( divide both sides by π )

r² = 576 ( take the square root of both sides )

r = \sqrt{576} = 24

What is the average rate of change of the function in the table at the interval x = -1 to x = 1?
Andre45 [30]

Answer:

the answer is undefined

Step-by-step explanation:

If a function, f(x), is continuous (that is, has values for every x in the interval) from x=- 1 to x=1 ), then the average rate of change is:( total amount that f(x) changes ) / (total amount that x changes)( f(1) - f(-1) ) / ( (1) - (-1) )( f(1) - f(-1) ) / 2The variable x changes from (-1) to (1). That value is 2. [note: (1)-(-1) ]The function changes from f(-1) to f(1). You must determine f(1)-f(-1) and use that value as the numerator.Fill in the values to determine the average rate of change: ( f(1) - f(-1) ) / 2However, if the plot of y values is not a function, and there is some x value between -1 and 1 for which f(x) is undefined, then the rate of change of y from f(-1) to f(1) is also undefined.

Then value of gold is appreciating 18% every hour you were lucky enough to have gold coin which was worth $40 at the beginning o
Zepler [3.9K]

Answer:

The equation is  y=40(1.18)^{x}

Step-by-step explanation:

The exponential growth equation is  y=a(1 + r)^{x} , where

  • a is the initial value (value y at x = 0)
  • r is the rate of increasing in decimal

∵ The value of gold is appreciating 18% every hour

∴ r = 18%

∵ 18% = \frac{18}{100} = 0.18

∴ r = 0.18

∵ The gold coin was worth $40 at the beginning of the crisis

∴ The initial amount is $40

∴ a = 40

∵ y represents the value of the gold after x hours

∴ y=a(1+r)^{x}

- Substitute the values of a and r in the form above

∴ y=40(1+0.18)^{x}

∴ y=40(1.18)^{x}

The equation is  y=40(1.18)^{x}
