PLEASE ANSWER ASAP
Nastasia [14]

Answer:

y = 4 (2)^{x}

Step-by-step explanation:

For an exponential function in standard form

y = a (b)^{x}

To find the values of a and b, use ordered pairs from the table

Using (0, 4 ), then

4 = ab^{0} ( b^{0} = 1 ), so

a = 4

y = 4b^{x}

Using (1, 8 ), then

8 = 4b^{1} = 4b ( divide both sides by 4 )

2 = b

Thus

y = 4 (2)^{x} ← exponential function

The seventh grade choir sold pizzas as a fundraiser. The choir teacher created the graph below for the students.
frez [133]

Answer:

C

Step-by-step explanation:

We are trying to find the profit for every pizza sold. Since looking at the x axis, the point in which its x coordinate is 1 cannot be easily identified. Thus, we shall derive the answer using a point that can be easily identified.

We observe that the two points, (10,12) and (20,24) sits nicely on the graph. I will be using the first coordinate above to derive the answer.

For every 10 pizzas sold, $12 of profit is made.

10 pizzas ----- $12 profit

1 pizza ----- $12 ÷10= $1.20

Hence, the unit rate of profit for the pizzas is $1.20 per pizza.

LOOK AT PICTURE. VOLUME OF CAN PROBLEM
adoni [48]

Answer:

The correct answer is third option.  994

Step-by-step explanation:

<u>Points to remember</u>

Volume of cylinder = πr²h

Where 'r' is the radius and 'h' is the height of cylinder

From the given question we get the cylinder height and radius

The height h = 3 times the diameter of one ball

 = 3 * 7.5 = 22.5 cm

Radius = half of the diameter of a ball

 = 7.5/2 = 3.75 cm

<u>To find the volume of cylinder</u>

Volume of cylinder = πr²h

 = 3.14 * 3.75² * 22.5

 = 993.515 ≈ 994

The correct answer is third option.  994
