Alright Soldier I need help, Solve for Percent Error, Calculate the percent error if the experimental value of the density of go
Dima020 [189]

Answer:

Step-by-step explanation:

so the steps to doing this are as follows :

Subtract the accepted value from the experimental value.

Take the absolute value of step 1.

Divide that answer by the accepted value.

Multiply that answer by 100 and add the % symbol to express the answer as a percentage.

|18.7-19.3|/19.3 = 0.031088 * 100% = 3.1%

Which of the equations are true identities? a. (3x-2y)(2y-3x)=9x^2-4y^2 b. (2k+5r)(2k-5r)=4k^2-25r^2
krok68 [10]

Answer:

b.(2k+5r)(2k-5r)

Step-by-step explanation:

We have to find the equation which are true identity.

a.(3-2y)(2y-3x)

(3x-2y)(2y-3x)=3x(2y-3x)-2y(2y-3x)

=6xy-9x^2-4y^2+6xy

(3-2y)(2y-3x)\neq 9x^2-4y^2

b.(2k+5r)(2k-5r)

(2k)^2-(5r)^2

Using identity

(a+b)(a-b)=a^2-b^2

4k^2-25r^2

It is true.

Hence, option b is true.

4. Find the power set for set A= {a,b,c}.
artcher [175]

Answer:

Remember, the power set of any set S is the set of all subsets of S, including the empty set and S itself.

Then the power set of A=\{a,b,c\} is

\{\emptyset, \{a\}, \{b\}, \{c\}, \{a,b\}, \{a,c\}, \{b,c\}, \{a,b,c\}\}
