Answer:

(x - 2)^2 + (y + 1)^2 = 9

Step-by-step explanation:

recall the equation for a circle:

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

here (h, k) = (2, -1)

and r = 3

(x - 2)^2 + (y -(-1))^2 = 3^2

(x - 2)^2 + (y + 1)^2 = 3^2

(x - 2)^2 + (y + 1)^2 = 9

Please help!!!! Sine and cosine ratios

Kipish [7]

Answer: 40.9

Step-by-step explanation:

Given

angle given is $23^{\circ}$

$RC=16$

Using trigonometry

$\Rightarrow \sin 23^{\circ}=\dfrac{RC}{PC}\\\\\Rightarrow \sin 23^{\circ}=\dfrac{16}{X}\\\\\Rightarrow X=\dfrac{16}{\sin 23^{\circ}}\\\\\Rightarrow X=40.948\approx 40.9$

Using cosine formula

$\Rightarrow \cos 23^{\circ}=\dfrac{PR}{X}\\\\\Rightarrow PR=40.9\times \cos 23^{\circ}\\\Rightarrow PR=37.69\approx 37.7$

A helicopter flies at a rate of 150 miles per hour. How many miles per second is this

den301095 [7]

Answer:

So,converting 150 mile per hour into miles per second we get 0.0416 miles per second

Step-by-step explanation:

Given:

Helicopter files at: 150 miles per hour

Required:

We need to convert 150 miles per hour to miles per second

Solution:

We know that, $1 \ mile\ per\ hour = \frac{1}{3600} \ miles\ per\ second$

So, 150 mile per hour will be: (We will be dividing 150 by 3600 to get miles per second)

$1 \ mile\ per\ hour = \frac{1}{3600} \ miles\ per\ second\\150 \ mile\ per\ hour = \frac{150}{3600} \ miles\ per\ second\\150 \ mile\ per\ hour = 0.0416 \ miles\ per\ second$

So,converting 150 mile per hour into miles per second we get 0.0416 miles per second
