B. Yes it's an exponential function because the y is increasing rapidly without a constant rate of change

Answer:  Yes, the given table represents an exponential function y=e^x.

The correct option is (B) Yes.

Step-by-step explanation:  We are given to check whether the following table represents an exponential function or not :

x |       1      |       2      |       3      |      4      |

-----------------------

----------------------------------

y |       3      |       9      |      27    |      81      |

We see that

3=3^1,~~~9=3^2,~~~27=3^3,~~~81=3^4,~~~~~etc.

Since the values of y are all powers of 3, so let us consider that the exponential function is written as :

y=3^k.

We have

If x = 1, then y=3^1=3,

If x = 2, then y=3^2=9,

If x = 3, then y=3^3=27,

IIf x = 4, then y=3^4=81,

.     .     .

.     .      .

Thus, the table represent an exponential function y=e^x.

Option (B) is CORRECT.

Identify the probability to the nearest hundredth that a point chosen randomly inside the rectangle is in the triangle. HELP PLE
sashaice [31]

Answer:

0.02

Step-by-step explanation:

we know that

The probability that a point chosen randomly inside the rectangle is in the triangle is equal to divide the area of the triangle by the area of rectangle

Let

x-----> the area of triangle

y----> the area of rectangle

P -----> the probability

P=x/y

<em>Find the area of triangle (x)</em>

A=(1/2)(5)(2)=5\ in^{2}

<em>Find the area of rectangle (y)</em>

A=18*12=216\ in^{2}

<em>Find the probability P</em>

P=5/216=0.02

Steve makes a banner with an area of 8 square feet. On a grid, draw all possible rectangles with an area of 8 square feet and si
Maksim231197 [3]

Answer:

The correct answers are with side lengths 1 feet and 8 feet, the perimeter is 18 feet; and with side lengths 2 feet and 4 feet, the perimeter is 12 feet.

Step-by-step explanation:

The area of a rectangular banner is 8 square feet.

The side lengths of this rectangular banner are whole numbers.

Thus the possible pairs of side lengths that would give 8 when multiplied with each other are (1 , 8) ; (2 , 4).

So the possible side lengths are 1 feet and 8 feet or 2 feet and 4 feet.

The perimeter when the side lengths are 1 feet and 8 feet are 18 feet.

The perimeter when the side lengths are 2 feet and 4 feet are 12 feet.

Lane high school has 5 times as many students as park elementary. How many more students attend lane high school than park high
frosja888 [35]

Answer:

5 times as many

<em>BRAINLIEST, please!</em>

Step-by-step explanation:

I'd need more information about how many students there are at one of the schools. For example, if there are 200 students at Park Elementary, then there are 1000 at Lane High School since 200 x 5 = 1000. 1000 - 200 is 800, so there would be 800 more students at Lane High.
