The coordinates of P(x, y) is: A. P(Negative StartRoot 21 EndRoot, –2)

<h3>Coordinates of P(x, y)</h3>

Given:

Radians=3π/2

theta=-5/2

Hence:

Hypotenuse = - 5

Altitude = 2

Using  Pythagorean theorem

Hypotenuse² =  Altitude² + Base²

-5²= 2²  + Base²

25 ² - 4 ² = Base²

Base = √21

Thus P(x,y) :

= P(-√21 : -2)

Therefore the correct option is A.

A scientific calculator has 42 buttons. There are twice as many grey buttons as orange buttons. There are two more white buttons
Arlecino [84]

Answer:

x + 2x + 2x + 2 + 4x + 4 = 42

Step-by-step explanation:

Let us assume the number of orange buttons be x

So, the grey buttons be 2x

The white buttons would be 2x + 2

And the black buttons be 2(2x + 2) i.e. 4x + 4

Also the total is 42 buttons

So, the equation is

x + 2x + 2x + 2 + 4x + 4 = 42

Can You Help Me With numbers 6-8
k0ka [10]

Hello,

Your answers and explanations are below.

6 - 5xy

5 times the product of x and y. The product of x and y means to multiply. That is where we get this: xy. 5 times that product is where we add 5 to it and get this: 5xy.


7 - 4x

We get this because we know he gets $4 an hour. We just do not know how many hours he babysat. The hours is X and we multiply that by 4.


8 - 5.5

Take 8.3 and subtract 2.8 to find x. Once we do that we get 5.5, and that is X.


9 - We can't see the problem. It's cut off

Good Luck,

- I.A. -

to make 1 batch of lavender paint the ratio of cups of pink paint to cups of blue paint is 6 to 5. find two more raios of cups o
marshall27 [118]
Your ratio is 6:5

This means that it is 6/5.

You have to find a common number to either divide or multiply that can work for both the numerator and denominator.

6/5 doesn't have any common number to divide without getting a remainder

But we can multiply by a common number such as 2

6×2 = 12
5×2 = 10

= 12/10. ☆= the ratio is 12 : 10

or even by 3, =the ratio 18:15
