Select the correct answer1 - quadratic, linear, exponential2 - 1.5, 18, 16, 123 - 16, 12, 20, 184 - 18, 6, 20, 12

Alexxandr [17]

1 - The equation is:

$p(x)=-0.5x^2+6x$

Since it has no variable on exponents and it has a term with x to the second power, this is a quadratic function.

2 - x represents the length of the tomato patch, so if we want the area of the bell pepper patch, we can input x = 8 into the function:

$\begin{gathered} p(8)=-0.5\cdot8^2+6\cdot8 \\ p(8)=-0.5\cdot64+48 \\ p(8)=-32+48 \\ p(8)=16 \end{gathered}$

Thus, the area is 16 square feet.

3 - Since the leading coefficient is negative, the vertex of the parabola gives the maximum value for the function.

The x value of the vertex is:

$\begin{gathered} ax^2+bx+c \\ x_v=-\frac{b}{2a} \end{gathered}$

So, in this case:

$x_v=-\frac{6}{2\cdot(-0.5)}=-\frac{6}{-1}=6$

And to find the value for the area, we need to input that into the function:

$\begin{gathered} p(6)=-0.5\cdot6^2+6\cdot6 \\ p(6)=-0.5\cdot36+36 \\ p(6)=-18+36 \\ p(6)=18 \end{gathered}$

Thus, the maximum area is 18 square feet.

4 - The value for the length of the tomato patch is just the corresponding x for this maximum, which we calculated as the vertex x:

$x_v=6$

Thus, the length of the tomato patch for this maximum value is 6 feet.

A train travels 42 kilometers in 15 minutes. How far will the train travel in 3 hours at that speed?

SVETLANKA909090 [29]

To answer the problem above, we first find the velocity of the train that is travelling. It is calculated as follows:

Velocity = 42 km / 15 min = 2.8 km / min

The distance traveled after 3 hours at this speed is calculated by multiplying the velocity and the number of hours.

Distance = 2.8 km / min ( 3 hours ) ( 60 min / 1 hour ) = 504 km

If it takes 15 min to load 3 racks of buns, how many hours will it take to load 36 racks?

GrogVix [38]

Set up the equation of two ratios:

3 racks 36 racks
----------- = --------------
15 min x

Solve this for x: 3x =540; x = 180 minutes, or 3 hours

A rectangular prism has a base with a length of 25, a width of 9, and a height of 12. A second prism has a square base with a si

RSB [31]

Answer:

The height of the second prism is 12 units.

Step-by-step explanation:

First, we must know that the volume of a rectangular prism is equal to length x width x height. With this information, we can multiply the given dimensions of the first rectangular prism to get a volume of 2700 cubic units. From here, we must understand wha we need from the second rectangular prism. Because it has a square base of 15, that accounts for both its width and length. Therefore, we have that

$Volume= 15^2 x\\2700/225=x\\12=x$
