Last one, use trigonometry to help you solve for y given that one side is 4 and there is an angle of 50 degrees.

Ostrovityanka [42]

Answer:

y = 6.22

You can solve this in two ways.

1.) Use SOH CAH TOA:

I typically start off by labeling the sides of the triangle with H (hypotenuse), O (opposite), and A (adjacent). Because I need to figure out what y is when given an angle and 4, I will use CAH, or cosine.

$\cos(angle) = \frac{adjacent}{hypotenuse}$

$\cos(50) = \frac{4}{y}$

$\cos(50) \times y = 4$

$y = \frac{4}{ \cos(50) }$

$y = 6.22$

2.) Use Law of Sines:

Solve for the last angle inside the triangle first.

$180 - (50 + 90) = 40$

Then use the angle you found (40°) in the equation.

$\frac{4}{ \sin(40) } = \frac{y}{ \sin(90) }$

$\frac{4}{ \sin(40) } \times \sin(90) = y$

$y = 6.22$

An airplane is flying from New York City to Los Angeles. The distance it travels in miles, d, is related to the time in seconds,

fredd [130]

Answer: If it is traveling at 0.15 miles per second, it's speed is 540 miles per hour.

Step-by-step explanation:

Use the unit multiplier 3600sec/hrtimes 0.15 mile/sec.

.0.15 × 3600 = 540. Sec cancels so we're left with a speed in miles per hour.

Hope this helps

Solve the equation x=5/3 pi r ^3<br><br> A. <br> B<br> C<br> D?

maks197457 [2]

Answer:

B (3x / ( 5pi)) ^ 1/3 = r

Step-by-step explanation:

x=5/3 pi r ^3

Multiply each side by 3/5

3/5 x= pi r ^3

Divide each side by pi

3x / ( 5pi) = pi r^3 /pi

3x / ( 5pi) = r^3

Take the cube root of each side

(3x / ( 5pi)) ^ 1/3 = r^3 ^ 1/3

(3x / ( 5pi)) ^ 1/3 = r
