Answer:

1217

Step-by-step explanation:

Given

$Subjects = 2353$

$Improvement = 1136$

Required

The number that didn't improve --- missing from the question.

Let the unimproved be represented as x.

So, we have:

$x + Improvement = Subjects$

Substitute known values

$x + 1136 = 2353$

Solve for x

$x =- 1136 + 2353$

$x =1217$

Write an explicit formula for the arithmetic sequence whose common difference is -18

drek231 [11]

Let the first term be a(0). Then the formula for a(n) is a(0)-18(n-1).

Check: What's the first term? Let n = 1: a(1) = a(0)-18(1-1) = a(0) (correct)

What's the second term? Let -n =2: a(2) = a(0)-18(2-1) = a(0) - 18

and so on.

Prove that 1/sin^2A -1/tan^2A= 1

Vika [28.1K]

Answer:

Step-by-step explanation:

$LHS =\dfrac{1}{Sin^{2} \ A }-\dfrac{1}{Tan^{2} \ A }\\\\\\ = \dfrac{1}{sin^{2} \ A}- \dfrac{1}{\dfrac{Sin^{2} \ A}{Cos^{2} \ A}}\\\\\\= \dfrac{1}{sin^{2} \ A } - \dfrac{Cos^{2} \ A}{Sin^{2} \ A}\\\\\\= \dfrac{1-Cos^{2} \ A}{Sin^{2} \ A}\\\\\\= \dfrac{Sin^{2} \ A}{Sin^{2} \ A}\\\\\\= 1 = \ RHS$

Hint: 1 - Cos² A = Sin² A
