Which expression is equal to the example?

Aloiza [94]

$1-(cosx)^4$ value is $2sin^4-sin^4x$ . Correct option is D) $2sin^4-sin^4x$ .

<u>Step-by-step explanation:</u>

Here we have , expression to evaluate:

$1-(cosx)^4$

⇒ $1-((cosx)^2)^2$

⇒ $1-(1-(sinx)^2)^2$

We know that , $sin^2x = 1-cos^2x$ , putting value in equation $1-(1-(sinx)^2)^2$

⇒ $1-(1+sin^4x-2sin^4)$

⇒ $1-1-sin^4x+2sin^4$

⇒ $-sin^4x+2sin^4$

⇒ $2sin^4-sin^4x$

Therefore , $1-(cosx)^4$ value is $2sin^4-sin^4x$ . Correct option is D) $2sin^4-sin^4x$

The price of an item has risen to $207 today. Yesterday it was $180. Find the percentage increase

andriy [413]

Answer:

15% '

Step-by-step explanation:

Price yesterday = $180

Price today = $207

Increase in price = $(207 - 180)

=> $27

Percent increase =

Increase / Price of yesterday

=> 27 / 180 * 100

=> 3 / 2 * 10

=> 30 / 2

=> 15

15%

Therefore, the rise in the price of the item = 15%

What is the equation of the quadratic graph with a focus of (−4, seventeen eighths ) and a directrix of y = fifteen eighths

Lunna [17]

Standard form for a parabola:
( x - h )² = 4 p ( y - k )
Vertex: ( h, k ) = ( -4, 2 )
Displacement from vertex to focus:
p = 2/8 = 1/4
( x + 4 )² = 4 · 1/4 ( y - 2 )
y = ( x + 4 )² + 2
or general form:
x² + 8 x - y + 18 = 0
