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}\\

Does anyone know the answer to this

Hello!

We can write this as a proportion below.

\frac{blueprint}{real} = \frac{0.5}{4} = \frac{18}{x}

As you can see, 4 is eight times 0.5. Therefore, we can multiply eighteen by eight to get our answer.

18(8)=144

Just to check, we can cross multiply and divide.

72/0.5=144

Therefore, our answer is 144 feet.

I hope this helps!

Answer:

Step-by-step explanation:

The formula for this, specific to our circle, is

∠RQP = \frac{1}{2}(arc SP - arc RP) and filling in:

∠RQP = \frac{1}{2}(170-86) and

∠RQP = \frac{1}{2}(84) so

∠RQP = 42°

How many whole numbers leave a remainder of 2 when divided into 56, and a remainder of 1 when divided into 28? a.) 0 b.) 2 c.) 3
meriva

56 would have a remainder of 2 using multiples of 3

56/3 = 18 remainder 2

56/6 = 9 remainder 2

56/9 = 6 remainder 2

56/18 = 3 remainder 2

56/27 = 2 remainder 2

Now divide 28 by the above numbers to see which ones have 1 as a remainder:

28/3 = 9 remainder 1

28/6 = 4 remainder 4

28/9 = 3 remainder 1

28/18 = 1 remainder 10

28/27 = 1 remainder 1

There are 3 numbers that will work.

Answer: c. 3

Y varies directly with x, and y = 15 when x = 3. What is the value of x when y = 4?
TiliK225 [7]
When x = 3 , y = 15 , divide both by 3.
When x= 1 , y = 5. Now multiply both by 4/5
When x = 4/5 , y=4
