Answer: The correct option is 2.

Explanation:

From the given figure it is easily noticed that the graph intersect the y-axis at y=9 , therefore the y-intercept is (0,9).

To find the equation of the curve put x=0 in each option, If we get y=9 then that option is true.

Option 1:

y=(\frac{1}{2})^{(x+3)}-1

y=(\frac{1}{2})^{(0+3)}-1=\frac{1}{8}-1=\frac{-7}{8}

Option 2:

y=(\frac{1}{2})^{(x-3)}+1

y=(\frac{1}{2})^{(0-3)}+1=8+1=9

Option 3:

y=(\frac{1}{2})^{(x-1)}+3

y=(\frac{1}{2})^{(0-1)}+3=2+3=5

Option 4:

y=(\frac{1}{2})^{(x+1)}-3

y=(\frac{1}{2})^{(0+1)}-3=\frac{1}{2}-3=\frac{-5}{2}

Only the equation in option 2 have the y-intercept (0,9), therefore the correct answer is option second.

It is the second function:
y=(1/2)^(x-3)
When x=0, the exponent is -3.  (1/2)^-3 is 8.
y = 8+1 = 9

What is the best approximation for the area of this circle?
butalik [34]

Area =113.0ft^2 . Correct option is D) 113.0 ft² .

<u>Step-by-step explanation:</u>

Here we have , A circle labeled with radius = 6 ft . We need to find the best approximation for the area of this circle . Let's find out:

We know that area of circle = \pi r^2 , We have following parameters as

Radius = r = 6 ft\\\pi = 3.14\\Area= \pi r^2 = ?

So , Area of circle is

⇒ Area =\pi r^2

⇒ Area =(3.14) (6)^2

⇒ Area =(3.14) (36)^

⇒ Area =113.04ft^2

On Rounding off

⇒ Area =113.0ft^2

Therefore , Area =113.0ft^2 . Correct option is D) 113.0 ft² .

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r
saw5 [17]

Using exponential function concepts, it is found that it represents a decay of 0.9%.

<h3>What is an exponential function?</h3>

A decaying exponential function is <em>modeled </em>by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem, the function is:

A(t) = 9300(0.991)^{6t}

Hence:

1 - r = 0.991

r = 0.009

Thus, it represents a decay of 0.9%.
