The volume of the triangular prism is 54 cubic units.

Please consider the diagram.

We have been given that the volume of the triangular prism is 54 cubic units. We are asked to find the value of x.

We know that volume of triangular prism is equal to area of base times height of the prism.

We can see from the attachment that base of prism is triangle. The area of the base of prism would be equal to area of triangle.

\text{Area of base}=\frac{1}{2}\cdot 4\cdot x

\text{Area of base}=2\cdot x

Now we will multiply base area with height of prism 3x.

V=2x\cdot 3x

V=6x^2

Let us equate volume of prism with 54 as:

6x^2=54

\frac{6x^2}{6}=\frac{54}{6}

x^2=9

Take positive square root on both sides:

\sqrt{x^2}=\sqrt{9}

x=3

Therefore, the value of x is 3 and option A is the correct choice.

After 30 minutes from the time recipe is kept in the oven, then the temperature of the oven is kept at 350 °F.

<h3>What is a function?</h3>

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

A pumpkin pie recipe says to bake the pie at 425°F for 15 minutes, and then to adjust the temperature down to 350°F for 45 additional minutes.

The function P(t) gives the oven temperature setting t, in degrees Fahrenheit, t minutes after the pie is placed in the oven.

Diego discovers that the temperature inside the oven is always 25 degrees warmer than the oven’s temperature setting.

The function B gives the actual temperature of Diego’s oven.

If P(30) = 350. Then the corresponding point on the function B will be

The temperature function can be written as

P(t)=\begin{Bmatrix}425 & 0\leq t\leq 15 \\\\350 & 15 < t\leq 60 \\\end{Bmatrix}

The value of t = 30 lies in the interval of 15 < t ≤ 60.

After 30 minutes from the time recipe is kept in the oven, then the temperature of the oven is kept at 350 °F.

More about the function link is given below.
