Answer:

-v

Step-by-step explanation:

The opposite vector is the vector that has the same magnitude of the original vector but points in opposite direction.So the vector -v has the same magnitude as the vector v but points to the opposite direction. Vector -v will start from the point 6 and will end at the point 3.That is opposite of the vector v which starts from point 3 and ends at point 6.

Hence the answer is -v.

Ellen wants to purchase a book that is regularly priced at $18. The book is discounted 15%. She also needs to pay a 6% sales tax

Viefleur [7K]

Answer:

Ellen will pay $16.22 for the book.

Step-by-step explanation:

Part 1:

We know that the book Ellen wants to buy has a normal price of $18. However, there is a 15% discount. So, let's calculate 15% of $18.

18 x 0.15 = $2.70

This lets us know that there is a $2.70 discount.

Now, let's subtract the discount from the regular price.

18 - 2.70 = $15.30

So, now we know the discounted price is $15.30

Part 2:

We also know that Ellen has to pay 6% sales tax. The discounted price is 100% of the price, plus 6% is 106%. Let's calculate the tax to figure out the total amount.

15.30 x 1.06 = $16.22 when rounded to the nearest cent.

Therefore, Ellen will pay the total amount of $16.22.

Double and half angle identities?

Maru [420]

Answer:

Option 4

Step-by-step explanation:

Given:

Sinθ = $\frac{15}{17}$

Since, cos2θ = 1 - 2sin²θ

cos2θ = $1-2(\frac{15}{17})^2$

cos2θ = 1 - $\frac{450}{289}$

cos2θ = $\frac{289-450}{289}$

cos2θ = $-\frac{161}{289}$

Therefore, Option 4 will be the answer.

How these question will get solve ? Please help.

Ok so look

we have
2√3+3√3-4√3
easy
remember taht 2√3 means 2 times √3 or √3+√3
it tells how many of that
so just add the numbers
2+3-4=1
1√3 or √3 is answer

2.
first simplfy each radical

5√32=5(√16)(√2)=5(4)(√2)=20√2
2√50=2(√25)(√2)=2(5)(√2)=10√2
now we have
20√2+10√2
just add
30√2

1. √3
2. 30√2
