HELP ASAP TIMED !!!! What is the exact value of cos(c + d), given Sine c = StartFraction 24 Over 25 EndFraction for c in Quadran
Keith_Richards [23]

9514 1404 393

Answer:

  D

Step-by-step explanation:

In the second quadrant, ...

  c = 180° -arcsin(24/25) ≈ 106.26°

In the third quadrant, ...

  d = 360° -arccos(-3/4) ≈ 221.41°

Then cos(c+d) = cos(327.67°) ≈ 0.84498

This is a positive irrational number, greater than 21/100, so the only reasonable choice is the last one:

  \dfrac{21+24\sqrt{7}}{100}\approx 0.84498

_____

Perhaps you want to work this out using the trig identities.

  cos(c) = -√(1 -sin(c)²) = -7/25

  sin(d) = -√(1 -cos(d)²) = -(√7)/4

Then the desired cosine is ...

  cos(c+d) = cos(c)cos(d) -sin(c)sin(d)

  cos(c+d) = (-7/25)(-3/4) -(24/25)(-√7/4)

  cos(c+d) = (21 +24√7)/100 . . . . matches choice D

The parent function f (x)= 2^xis reflected across the x-axis,
skad [1K]

Answer:

F(x) = 2^{x+2} - 6

Step-by-step explanation:

To shift a function F(x) a units to the left, we do:

F(x) = F(x+a)

In this problem, we have that:

F(x) = 2^{x}

So, shifting 2 units left:

F(x) = 2^{x+2}

Then

To shift a units down, we do:

F(x) = F(x) - a. So[tex]F(x) = 2^{x+2}

Shifting 6 units down

F(x) = 2^{x+2} - 6
