Point Q was rotated about the origin (0,0) by -45 degrees

Answers

Answer:

0,0

Step-by-step explanation:

The point Q was rotated about the origin (0,0) by -45 degrees, so the new coordinate point is (√2, 4√2).

From the given graph, the coordinates of point Q are (-3, 5).

Rotating the co-ordinate axes through an angle of 45° in anti-clockwise direction is equivalent to rotating the point through an angle of -45° about origin.We will use rotation from complex numbers to solve this.

Let x + iy the new complex number

(-3+5i)[tex]e^{\frac{-\pi i}{4} }[/tex]

= (-3+5i)((1-i)/√2)

= (-3+5i)(1-i) ×1/√2

= (-3+5i+3i-5i²) ×1/√2

= (-3+8i+5) ×1/√2

= (2+8i) ×1/√2

= (2/√2 + 8i/√2)

= (√2 + 4√2i)

So, the coordinates are (√2, 4√2)

Therefore, the point Q was rotated about the origin (0,0) by -45 degrees, so the new coordinate point is (√2, 4√2).

Use the dot product to find v when v=(-2 -1)
a. -1 c. √5
b. -3 d. √3

Answers

Since you're only given the one vector, I assume you're supposed to find the magnitude of v, or ||v||, using the dot product.

We have

v • v = (-2, -1) • (-2, -1) = (-2)² + (-1)² = 5

so that

||v|| = √(v • v) = √(5)

and the answer is C.

The regular price of a coat is $35.25. During a sale, the coat rang up for $19.99. What was the percent off of the coat during the sale? (5 points)

a
The sale was for a 43% decrease.

b
The sale was for a 76% increase.

c
The sale was for a 76% decrease.

d
The sale was for a 43% increase.

Answers

Answer:

a

The sale was for a 43% decrease.

Step-by-step explanation:

The computation of the percent off of the coat during the sale is shown below:

Regular price is $35.25

And, in the sale the price is $19.99

So, the percent off would be

= ($35.25 - $19.99) ÷ ($19.99)

= 43% decrease

hence, the percent off of the coat during the sale is 43% decrease

Therefore the correct option is a.

And, all the other options are incorrect

One cellphone provider DU charges AED10 per month plus an activation fee of AED20. A second cellphone provider ETISALAT charges AED11 per month plus an activation fee of AED15. For what number of months is the cost of either cellphone provider the same?

Answers

Answer:

5 months

Step-by-step explanation:

One cellphone provider charges AED10 per month plus an activation fee of AED20.

If I used the services of this cellphone provider for x months, total charges for the services,

y = 10x + 20 --------(1)

Similarly, charges for the second cellphone provider for x months of uses will be,

y = 11x + 15 -------(2)

Answers

Answer:

54

Step-by-step explanation:

So If this tells you what 'm' and 'n' are, you just put them inside.

First do the M so then it will be 5 * 10 which is 50 then we just first leave it there.  Then we start putting in that N. We know that N is 4. Then it's N to the power of 2. I recommend since there's already a 4 on the bottom, just do 4 * 4 there. Then you see there is a 4 on the denominator while there are double 4's on the numerator. Then you just cross one 4 on the denominator and one on the numerator to simplify it.

Then all there is is 50 + 4 = 54

So 54 is our answer.

Answer:

Step-by-step explanation:

10m + n^2/4           (m=5 , n=4)

Find the value of x in the

Answer:

[tex]x = 4[/tex]

Step-by-step explanation:

See attachment for complete question

From the attachment, the parallelogram has two diagonals. And the diagonals of a parallelogram bisect one another.

Because 2x - 1 and 7 are opposite sides of a diagonal; We can say that:

[tex]2x - 1= 7[/tex]

Add 1 to both sides

[tex]2x - 1 + 1 = 7 + 1[/tex]

Answer:

Step-by-step explanation:

2) ∠A + ∠B = 146       {Exterior angle theorem}

5y + 3 + 4y + 8 = 146

5y + 4y + 3 + 8 = 146           {combine like terms}

         9y + 11 = 146

               9y = 146 -11

               9y = 135

                 y = 135/9

y = 15

3) m∠A = 5y + 3

              = 5*15 + 3

              = 75 + 3

A = 78

4) m∠B = 4y + 8

            = 4*15 + 8

            = 60 + 8

      m∠B = 68

5) m∠ACB + m∠A + m∠B = 180   {Angle sum property of triangle}

 m∠ACB  + 78 + 68 = 180

           m∠ACB + 146 = 180

                       m∠ACB = 180 - 146

                      m∠ACB = 34

Andy, Fergus, Evelyn, and Margaret are collecting cans for recycling. Before lunch they have collected a total of 173 cans. At the end of the day, the total number of cans collected can be represented by the expression 173 + n . What does the variable n in the expression represent?

Answers

Answer:

n = The number of can collected after lunch

Step-by-step explanation:

Andy, Fergus, Evelyn, and Margaret are collecting cans for recycling.

From the question, the told number rod cans collected before lunch = n

We are told that :

At the end of the day, the total number of cans collected can be represented by the expression 173 + n .

The total number of cans = Number of cans collected before lunch + Number of cans collected after Lunch

Hence:

173 + n = 173 + Number of cans collected after Lunch

Therefore, the variable n = Number of cans collected after Lunch

Sumalee and Scott each improved their yards by planting daylilies and ivy. They bought their
supplies from the same store. Sumalee spent $93 on 6 daylilies and 3 pots of ivy. Scott spent
$196 on 13 daylilies and 6 pots of ivy. Find the cost of one daylily and the cost of one pot of ivy.

Answers

Answer:

The cost of one daylily is $10 and the cost of one pot of ivy is $11

Step-by-step explanation:

To solve the question we will form a system of equations

Assume that the cost of 1 daylily is x and the cost of 1 pot of ivy is y

∵ Sumalee spent $93 on 6 daylilies and 3 pots of ivy

→ Multiply x by 6, y by 3, then add the products and equate the sum by 93

6x + 3y = 93 ⇒ (1)

∵ Scott spent $196 on 13 daylilies and 6 pots of ivy

→ Multiply x by 13, y by 6, then add the products and equate the sum by 196

13x + 6y = 196 ⇒ (2)

Now we have a system of equations to solve it

→ Multiply equation (1) by -2

∵ -2(6x) + -2(3y) = -2(93)

-12x - 6y = -186 ⇒ (3)

→ Add equations (2) and (3)

(13x + -12x) + (6y + -6y) = (196 + - 186)

∴ x + 0 = 10

x = 10

→ Substitute the value of x in equation (1) to find the value of y

6(10) + 3y = 93

∴ 60 + 3y = 93

→ Subtract 60 from both sides

∵ 60 - 60 + 3y = 93 - 60

∴ 3y = 33

→ Divide both sides by 3

y = 11

The cost of one daylily is $10 and the cost of one pot of ivy is $11
