Use trig identities to transform the left side of the equation to the right side.
Taya2010 [7]

<u>Answer and explanation</u>

(1+sinθ)(1-sinθ)=cos²θ

We are to prove that the left hand side is equal to the right hand side.

(1+sinθ)(1-sinθ) = 1(1-sinθ) + sinθ(1-sinθ)

                         = 1 - sinθ + sinθ - sin²θ

                          = 1 - sin²θ

From the trigonometric identity sin²θ + cos²θ = 1,

1 - sin²θ = cos²θ

Find the sample size, n, needed to estimate the percentage of adults who have consulted fortune tellers. Use a 0.02 margin of er
Brrunno [24]

Answer: 2172

Step-by-step explanation:

Formula to find the sample size n , if the prior estimate of the population proportion(p) is known:

n= p(1-p)(\dfrac{z^*}{E})^2 , where E=  margin of error and z* = Critical z-value.

Let p be the population proportion of adults have consulted fortune tellers.

As per given , we have

p= 0.20

E= 0.02

From z-table , the z-value corresponding to 98% confidence interval = z*=2.33

Then, the required sample size will be :

n= 0.20(1-0.20)(\dfrac{2.33}{0.02})^2

n= 0.20(0.80)(116.5)^2

n= 2171.56\approx2172

Hence, the required sample size = 2172

Which statement proves that parallelogram KLMN is a rhombus?
IrinaVladis [17]

Answer:

It is the last option.

Step-by-step explanation:

The diagonals of a rhombus (KM and NL ) are perpendicular. That is shown by the diagonals having slopes of 1 and -1.

Recall that when  2 lines are perpendicular then m1 * m2 = -1 , where m1 and m2 are the slopes of the lines.
