Answer:

Table 2 is the right representation of exponential functio.

Step-by-step explanation:

We are given the following information in the question:

y = b^k,\\0

If we look at table 2, then, the exponential function is of the form:

y(x) = \bigg(\displaystyle\frac{1}{3}\bigg)^x

Putting different values of x, we have:

x = -3\\\\y(-3) = \bigg(\displaystyle\frac{1}{3}\bigg)^{-3} = 27\\\\x = -2\\\\y(-2) = \bigg(\displaystyle\frac{1}{3}\bigg)^{-3} = 9\\\\x = -1\\\\y(-1) = \bigg(\displaystyle\frac{1}{3}\bigg)^{-1} = 3\\\\x = -0\\\\y(0) = \bigg(\displaystyle\frac{1}{3}\bigg)^{0} = 1\\\\x = 1\\\\y(1) = \bigg(\displaystyle\frac{1}{3}\bigg)^{1} = \frac{1}{3}\\\\x = 2\\\\y(2) = \bigg(\displaystyle\frac{1}{3}\bigg)^{2} = \frac{1}{9}\\\\x = 3\\\\y(3) = \bigg(\displaystyle\frac{1}{3}\bigg)^{3} = \frac{1}{27}\\

Brilliant question!!!!
avanturin [10]

Answer:

a) 21

b) 78.5 - 28.3 - 12.57 = 37.63

Step-by-step explanation:

For the triangle, you want to use the formula 1/2 base times height and then subtract 2 time 2. For the circle, the formula is pi times the radius squared. Then, subtract the other circles using the same formula. I hope this helps! Please mark me brainliest because I have been scammed many times. Please and thank you.

Sam needs a web designer. Designer A is offering her services for an initial $450 in addition to $105 per hour. Designer B is of
gogolik [260]

Answer:

After 5 hours the two would charge the same amount of money.

Step-by-step explanation:

Designer A:  $450 + ($105/hr)x, where x is the number of hours worked;

Designer B:  $725 + ($50/hr)x

Equating these two formulas, we get:

$450 + ($105/hr)x = $725 + ($50/hr)x

Subtracting $450 from both sides:  ($55/hr)x = $275

Dividing both sides by $55 yields the number of hours worked:

x = $275/$55 = 5

After 5 hours the two would charge the same amount of money.
