Answer:

See below

Step-by-step explanation:

Use identities:

sin 2x = 2sinxcosx
cos 2x = cos²x - sin²x

Simplify the given:

sin 2x / (1 - cos 2x) =
2sin x cos x / (sin² x + cos² x - cos² x + sin² x) =
2sin x cos x / 2sin² x =
cos x / sin x =
cot x = tan (90° - x) (in the quadrant I)

Apply to the given:

sin (44°) / (1 - cos (44°)) =
tan (90° - 44°/2) =
tan (90° - 22°) =
tan (68°)

Line AB contains points A (4,5) and B(9,7). What is the slope of AB

ki77a [65]

This line crosses the point (4,5)so we can make an equation to find the slope:
$4 = a \times 5 \\ 4 = 5a \\ a = \frac{4}{5}$
hope this helps

A baseball player swings and hits a pop fly straight up in air to the catcher. the height of the baseball in meters t seconds af

Ludmilka [50]

$h(t)=-4.9t^{2}+34.3t+1
\\h'(t)=(-4.9t^{2}+34.3t+1)'=-9.8t+34.3
\\h'(t)=0
\\-9.8t+34.3=0
\\
\\t= \frac{34.3}{9.8} =3.5
\\
\\h_{max}=h(3.5)=-4.9\times3.5^{2}+34.3\times3.5+1=61.025$

The ball reaches its maximum height after 3.5 seconds, and the maximum height is 61.025 meters.
