3 0

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

• tanx = \frac{sinx}{cosx}

• sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x

Consider the left side

\frac{tan^2x-sin^2x}{tan^2x}

= \frac{tan^2x}{tan^2x} - \frac{sin^2x}{tan^2x}

= 1 - cos²x

= sin²x = right side ⇒ verified

Answer asap!!! which equation could be used to find the perimeter of a rectangle that has a width of 10 inches and a length of 2
Arlecino [84]

Answer:

d. p = 2*20 + 2*10

Step-by-step explanation:

You know to find the perimeter, just add side + side + side + side.

And two pairs of sides on a rectangle are congruent, so the missing side lengths based on the width and length, will be 20 & 10.

So add 20 + 20 + 10 + 10.

To simplify this, say 2*20 and 2*10. And then add them.

So it is D

Identify the equation of the circle D with center D(−8,−1) and radius 3.
REY [17]

Answer:

(h+8)^2 + ( y +1)^2 = 9

Step-by-step explanation:

The equation of a circle can be written as

(x-h) ^2 +(y-k) ^2 = r^2

where (h,k) is the center and r is the radius

(h- -8)^2 + ( y - -1)^2 = 3^2

(h+8)^2 + ( y +1)^2 = 3^2

(h+8)^2 + ( y +1)^2 = 9

The local cable company charges $90 per month for basic and $12 per month for each additional premium cable channel.The function
Alika [10]

Answer:

2 additional premium channels

Step-by-step explanation:

Using the given function, we substitute c(x) = 114 and solve for x:

114 =90 + 12x

Subtract 90 from both sides:

24=12x

Divide both sides by 12:

2=x

So you have ordered 2 additional premium channels.
