An aquarium has a base in the shape of a trapezoid. The base is 100

Nat2105 [25]

Answer:

$Volume = 210L$

Step-by-step explanation:

Given

Base:

$Front = 100cm$

$Back = 50cm$

$Width = 40cm$

$Height = 70cm$

Required

Determine the volume (in litres)

First, we need to calculate the area;

Base on the parameters given, we have:

$Area = \frac{1}{2}(Front + Back) * Width$

$Area = \frac{1}{2}(100cm + 50cm) * 40cm$

$Area = \frac{1}{2}(150cm) * 40cm$

$Area = 75cm * 40cm$

$Area = 3000cm^2$

$Volume = Area * Height$

$Volume = 3000cm^2 * 70cm$

$Volume = 210000cm^3$

$1cm^3 = 0.001L$

So:

$Volume = 210000 * 0.001L$

$Volume = 210L$

The roots of the function f(x) = x2 – 2x – 3 are shown. what is the missing number? x = –1 and x =

andrey2020 [161]

we have

$f(x)=x^{2}-2x-3$

Find the roots

Equate the function to zero

$x^{2}-2x-3=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$x^{2}-2x=3$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$x^{2}-2x+1=3+1$

$x^{2}-2x+1=4$

Rewrite as perfect squares

$(x-1)^{2}=4$

Square root both sides

$(x-1)=(+/-)2$

$x=1(+/-)2$

$x=1+2=3$

$x=1-2=-1$

therefore

<u>the answer is</u>

$x=3$
