Answer:

1 - cosΘ

Step-by-step explanation:

using the identity

sin²x + cos²x = 1 , then

sin²x = 1 - cos²x

\frac{sin^20}{1+cos0}

= \frac{1-cos^20}{1+cos0} ← factor 1 - cos²Θ as a difference of squares

= \frac{(1-cos0)(1+cos0)}{1+cos0} ← cancel 1 + cosΘ on numerator/ denominator

= 1 - cosΘ

Suppose f is a function which follows this pattern, where x and h are any numbers: f(a + h) = f(a)*f(h) Which type of function i
fomenos

f has to be a <em>power</em> function in order to satisfy the recurrence pattern f(x + h) = f(x) \cdot f(h)

<h3>Procedure - Determination of a function with a pattern.</h3>

In this case, we must assume a given function and check such assumption fulfill the given recurrence. Let suppose that f(x) = a^{x}, by algebra we have the following property:

f(x + h) = a^{x+h} = a^{x}\cdot a^{h} (1)

And by the definition given in statement, we have the following conclusion:

f(x+h) = a^{x}\cdot a^{h} = f(x) \cdot f(h) (2)

Therefore, f has to be a <em>power</em> function in order to satisfy the recurrence pattern f(x + h) = f(x) \cdot f(h). \blacksquare

The following data are arranged in ascending order and the median of the data is 60.
choli [55]
The median of the data is 60. That means the two middle numbers divided by 2 = 60.

(x + x + 2) / 2 = 60...multiply by 2
2x + 2 = 120
2x = 120 - 2
2x = 118
x = 118/2
x = 59

x + 2 = 59 + 2 = 61

so ur numbers go : 26,29,42,53,59,61. 70, 75, 82, 93

In circle E with m \angle DEF= 70m∠DEF=70 and DE=13DE=13 units find area of sector DEF. Round to the nearest hundredth.
Anuta_ua [19.1K]

Answer:

103.18units³

Step-by-step explanation:

Area of the sector DEF = theta/360 * πr²

r is the radius

theta is the angle subtended at the centre

theta =70 degrees

radius DE = 13units

Substitute

Area of the sector = 70/360 * 3.14(13)²

Area of the sector = 7/36 * 530.66

Area of the sector = 3,714.62/36

Area of the sector = 103.18units³ (to the nearest hundredth)
