X would be r*cos theta and y  would be r*sin theta.

Here, x is 5cos 135 deg = 5(-1/sqrt(3))
and    y is 5* sin 135 deg = 5*(1/sqrt(3))


Write this point in the form (x,y), using the above values for x and y.

What is the next value 4d 7g 10j 13
bearhunter [10]
13m 16p

Add three to every number next as well as move up three letters.

For example:
1A is the starting point.
To get from 1A to 4D you add three.

1 + 3 = 4
A to get to D is three letters up.
A b c D

Same thing for 4D to get to 7G.

4 +3 = 7
D to get to G
D e f G

Your answer:
I'm not sure if you wanted me to find the letter of the equation or the actual next part. On your question you have just 13 up there, no letter so if youre trying to find the letter (13m) is your answer.

If you're trying to find the next equation to the puzzle (16p) is your answer.

Hope this helped!:)

Which equation correctly applies the distributive property?
lesantik [10]

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

Distributive law is defined as

a\times (b+c+d)=a\times b+a\times c+a\times d

According to option'A', we get that

a =- 3

b = 6

c = 0.4

d = 0.08

So, it becomes,

-3\times (6.48)=-3\times 6+(-3)\times 0.4+(-3)\times 0.08

Hence, option 'A' is correct.

jenny wants to buy a winter coat for $200. the store advertises that customers can take 25% off the original price and then take
777dan777 [17]
Hello!

Let's check:

200 * 25% = 50

200 - 50 = 150

150 * 10% = 15

150 - 15 = 135

So, with the 25% and then an extra 10% off, the coat would cost $135.

200 * 35% = 70

200 - 70 = 130

So, Jenny's friend is incorrect, because that is not the same as a 35% discount.
