Answer: $4\ g/cm^3$

Step-by-step explanation:

The formula to find the density is given by :-

$\text{Density}=\dfrac{\text{Mass}}{\text{Volume}}$

Given : Mass of a n object= 20 g

Volume of object = $5\ cm^3$

Then the object's density will be :_

$\text{Density}=\dfrac{20}{5}\\\\\Rightarrow\ \text{Density}=4\ g/cm^3$

Hence, the object's density - $4\ g/cm^3$

Density = mass / volume

density = 20/5 = 4 g/cm^3

The slope f '(x) at each point (x, y) on a curve. y = f (x) is given along with a particular point (a, b) on the curve. Use this

Advocard [28]

Answer:

Step-by-step explanation:

Integrating each term with respect to x, we get:

x^3 x^2

f(x) = 9--------- + 4------- - 4x + C

3 2

We are told that if x = 0, f(x) = -7, and so C must equal - 7.

The solution is

x^3 x^2

f(x) = 9--------- + 4------- - 4x - 7, or f(x) = 3x^3 + 2x^2 - 4x - 7

A wooden rod of 5 m 75 cm was cut into 5 equal pieces. What is the length of each piece.

hram777 [196]

We have: 5m 75cm = 5.75 m

So the length of each piece is : $l = \frac{5.75}{5} =1.15$

ok done. Thank to me :>

Solve the following system by any method -8x-8y=0 -8x+2y=-20

iVinArrow [24]

$\fbox{Solution by using Matrix}$

$\text{Linear Equation} = -8x-8y=0 , -8x+2y=-20$

$\text{Rewrite the linear equations above as a matrix}$

$\left[\begin{array}{ccc}8&-8&0\\-8&2&-20\\\end{array}\right]$

$\text{Apply to Row2 : Row2 + Row1}$

$\left[\begin{array}{ccc}8&-8&0\\-8&-6&-20\\\end{array}\right]$

$\text{ Simplify rows}$

$\left[\begin{array}{ccc}8&-8&0\\0&1&10/3\\\end{array}\right]$

$\text{Note: The matrix is now in echelon form.}$ $\text{The steps below are for back substitution.}$

$\text{Apply to Row1 : Row1 + 8 Row2}$

$\left[\begin{array}{ccc}8&0&80/30\\0&1&10/3\\\end{array}\right]$

$\text{ Simplify rows}$

$\left[\begin{array}{ccc}1&0&10/3\\0&1&10/3\\\end{array}\right]$

$\text{Therefore, the solution is}$

$x= \dfrac{10}{3} \ \text{and} \ \ y=\dfrac{10}{3}$
