Let a =9, b=2,c=5,d=3 1.4 abc / d^2 =
2.a+c^2 /(b+d)^2 +a=
3.a(b+cd)=
3.a^2(c-d)^2=
4.2(d+bc)/b^3+c=
5.b(a-c)^2=
6.b^2c^2d^2/a+1=
7.(a+b)(c-d)=
8.(4a-5b)^2=
9.c(a^2+4)=
10.2ab^2-cd=

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

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

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

y=sec x is the correct answer

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
