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
