Question 5.

Given:

• A ==> (7, 2)

• A' ==> (11, 2)

Let's locate and mark the possible centers of rotation.

Apply the rules of rotation:

Rotation about the x-axis: (x, y) ==> (x, -y)

Rotation about the y-axis: (x, y) ==> (-x, y)

Hence, we have:

• By rotation about the x-axis, we have:

Image of coordinates of A ==> (7, -2)

Image of coordinates of A' ==> (11, -2)

• By rotation about the y-axis, we have:

Image of coordinates of A ==> (-7, 2)

Image of coordinates of A' ==> (-11, 2)

A coat in London costs £60. The same coat in Dublin costs €105.60. The exchange rate is £1 = €1.65. In which city is the coat ch

Pie

Answer:

The coat is cheaper in London and it is 6.6 euros cheaper than in Dublin

Step-by-step explanation:

Given

Cost of coat in London = £60

Cost of coat in Dublin = €105.60

In order to find where the coat is cheaper, the price should be in same unit

It is also given that

£1 = €1.65

so,

Price of coat in Euro will be:

$P = 60 * 1.65 = 99$

So the price of coat in London is 99 Euros

Comparing both the prices we see that

Price in London < Price in Dublin

99 < 105.60

The difference in price is:

$=105.60-99= 6.6\ Euros$

Hence,

The coat is cheaper in London and it is 6.6 euros cheaper than in Dublin

Nancy randomly scattered one handful of seeds in her garden. The garden is circular and has a radius of 5 feet. Somewhere in the

Nitella [24]

We know that
the garden is circular--------------> r=5 ft
Area1=pi*r²=pi*5²=78.50 ft²

path 2 feet by 2 feet square (good soil for the seeds)
Area2=2*2=4 ft²

the probability that a seed will land in the 2 feet by 2 feet square=Area2/Area1
P=4/78.5=0.051 (5.1%)

the answer is 0.051 (5.1%)

What are the solutions to the equation x² = 169? Choose all answers that are correct. A. 13 B. –13 C. 84.5 D. –84.5

Nimfa-mama [501]

$x^{2} = 169$

First, we need to take the square root of each side.
$x = \pm \sqrt169$

Second, we now have to find the square root of 169 to solve this. Since 13 × 13 = 169, the square root of 169 is 13. The plus-minus symbol means in this case, the solution can be -13 and positive 13. To answer your question, option A) 13, and B) -13 are the solutions to the equation.
$x = \pm 13$

Answer: $\pm13$

Given the sequence −2,−8/3,−103,−4,−14/3,... find the recursive formula.

Alinara [238K]

I suppose the third term should say -10/3, not -103.

Notice that

-2 = -6/3

-4 = -12/3

so that, starting with the first term a(1) = -6/3, the every following term is obtained by subtracting 2/3.

-2 - 2/3 = -6/3 - 2/3 = -8/3

-8/3 - 2/3 = -10/3

-10/3 - 2/3 = -12/3 = -4

and so on.

So the recursive rule is

a(1) = -2,

a(n + 1) = a(n) - 2/3, for n ≥ 1

or C.
