Given that cosθ=7/25 , what is sinθ ?

OLga [1]

Answer:

sin θ = 24/25.

Step-by-step explanation:

Cos θ = 7/25 so we have a right triangle with adjacent side = 7 and hypotenuse = 25.

So the opposite side = sqrt ( 25^2 - 7^2) ( By Pythagoras)

= sqrt 576

= 24 .

Therefore sin θ = 24/25.

An airplane flew with the wind for 2.5 hours and returned the same distance against the wind in 3.5 hours. If the cruising speed

KengaRu [80]

Answer:

60 miles per hour.

Step-by-step explanation:

Let r represent speed of wind blowing in miles per hour.

We have been given that the cruising speed of the plane was a constant 360 mph in air. The speed of the plane is the direction of wind would be $360+r$ .

The speed of the plane is the opposite direction of wind would be $360-r$ .

$\text{Distance}=\text{Speed}\times \text{Time}$

Distance covered in the direction of wind would be $2.5(360+r)$ .

Distance covered in the opposite direction of wind would be $3.5(360-r)$ .

Since both distances are same, so we will get:

$2.5(360+r)=3.5(360-r)$

$900+2.5r=1260-3.5r$

$900-900+2.5r+3.5r=1260-900-3.5r+3.5r$

$6r=360$

$\frac{6r}{6}=\frac{360}{6}$

$r=60$

Therefore, the wind is blowing at a rate of 60 miles per hour.

What's +2 , 1/3+1/4 , 2^3 * 2^2?

snow_lady [41]

+ 2 = 2

1/3 + 1/4 = 4/12 + 3/12 = 7/12

2^3 * 2^2 = 8 * 4 = 32

Hope this helps! :)
