What is the mass of an object that has a density of 1.3 g/cm3 and a volume of 2 cm3? (The density of an object has the equation d.)

The mass of the object is 2.6 grams

Step-by-step explanation:

The density of an object is the ratio between its mass and its volume

The equation of the is d = , where

Let us use this equation to solve the question

∵ An object has a density of 1.3 g/cm³

∴ d = 1.3 g/cm³

∵ Its volume is 2 cm³

∴ V = 2 cm³

→ Substitute them in the equation of the denisty above

∵ 1.3 =

→ Multiply both sides by 2

∴ 2 × 1.3 = 2 ×

∴ 2.6 = m

∴ The mass of the object is 2.6 grams

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
