Step-by-step explanation:
The volume of the fish tank is 408 in³
To solve the volume of the fish tank, we need to understand what is the volume of plane shapes.
<h3>What is the volume of plane shapes?</h3>
The volume of plane shapes resembles a 3-dimensional space showing the area enclosed by the shape.
From the figure given:
The figure can be differentiated into two shapes;
The volume of the rectangle is known as:
- = Length × Breadth
- = 7 inches × 6 inches
- = 42 inches²
The volume of the triangle is:
- = 1/2 × base × height
- = 1/2 × 3 × 6
- = 9 inches²
The total volume of the base of the fish tank now is:
- = 42 inches² + 9 inches²
- = 51 inches²
Now, the volume of the fish tank is:
- = Height × base of the fish tank
- = 8 inches × 51 inches²
- = 408 in³

6x +5 = 8x after make the common denominator on both sides
5 = 2x
x = 5/2

The plot of a function <em>f(x)</em> is symmetric across the <em>y</em>-axis if it is even, meaning <em>f(-x)</em> = <em>f(x)</em> for all <em>x</em> in the function's domain.
The answer is then A because
(-<em>x</em>)² = (-1)² <em>x</em>² = <em>x</em>²
|-<em>x</em>| = |-1| |<em>x</em>| = |<em>x</em>|
cos(-<em>x</em>) = cos(<em>x</em>)
The answer is <u>not</u>
• B because sin(-<em>x</em>) = -sin(<em>x</em>) and (-<em>x</em>)³ = (-1)³ <em>x</em>³ = -<em>x</em>³
• C because -<em>x</em> ≠ <em>x</em> and again because of <em>x</em>³
• D because 1/(-<em>x</em>) = -1/<em>x</em> and again because of sin(<em>x</em>)
