Consider this equation (csc x+1)/cot x = cot x/(csc x +1) is it an identity?

1 answer:

7 0

Cross multiplying:-
cot^2 x = (csc x+ 1)(csc x + 1)

also cot^2 x = csc^2 x - 1 = (csc x + 1)(csc x - 1) (Known Identitiy)

so the equation is not an identity

A company sells boxes of small blue pom-poms (b) for $42 and boxes of large orange pom-poms (p) for $52. They make batches of sm

Strike441 [17]

Answer:

b = 40 - p

42b + 52p = 350

Step-by-step explanation:

Given : No. of small blue pom-pom boxes = b

No. of large orange pom-poms = p

cost of 1 box of blue pom pom = $42

cost of one large orange pom-pom box = $52

Solution:

Since we are given that the company has only 40 boxes

⇒b+p=40

⇒b=40-p

Since cost of 1 box of blue pom pom = $42

So, cost of b box of blue pom pom = $42b

Since,cost of one large orange pom-pom box = $52

So,cost of p large orange pom-pom box = $52p

We are also given that the company plan to make $350

⇒42b+52p=350

Hence Option b is correct

b = 40 - p

42b + 52p = 350

Brian needs to find the value of a number, a, so that when (x^2+3x) is added to the binomial (3x^2+ax), the sum simplifies to 4x

Julli [10]

Answer:

a = 9

Step-by-step explanation:

First we need to add (x^2+3x) to (3x^2+ax),

(x^2+3x)+(3x^2+ax)

Expand

= x^2+3x+3x^2+ax

Collect the like terms

= x^2+3x^2+3x+ax

= 4x^2 + 3x + ax

= 4x^2+(3+a)x

Equate the solution to 4x^2+12x

4x^2+(3+a)x = 4x^2+12x

Comparing the like terms on both sides

(3+a)x =12x

3 + a = 12

a = 12 - 3

a = 9

Hence the value of a is 9
