Answer: D. (-2, -1)

Step-by-step explanation:

Here we do two reflections to the point (-1, 2).

First, we do a reflection over the line x = y. Remember that a reflection over a line keeps constant the distance between our point and the given line, so we have that for a pint (x, y), the reflection over the line y = x is:

Ry=x (x, y) = (y, x)

so for our point, we have:

Ry=x (-1, 2) = (2, -1)

Now we do a reflection over the y-axis, again, a reflection over a line keeps constant the distance between our point and the given line, so if we have a point (x,y) and we do a reflection over the y-axis, our new point will be:

Ry-axis (x,y) = (-x, y)

Then in our case:

Ry-axis (2, -1) = (-2, -1)

The correct option is D.

√72 what is the non-perfect simplefied square root radical

Lostsunrise [7]

For simplifying radicals, remember the product rule of radicals: √ab = √a x √b . This radical is simplified as such:

√72 = √9 x √8 = 3 x √4 x √2 = 3 x 2 x √2 = 6√2

In short, the simplified radical of √72 is 6√2.

Nadia is a stockbroker. She earns 4% commission when she sells stocks. Last week, she earned $288 in commission.

Tresset [83]

Answer:

a)The total amount of her weekly stock sales = $7,200

b) The total amount of her yearly stock sales = $350,000

Step-by-step explanation:

(a) Let us assume that the total a mount of her sales in a week = $m

Commission earned in a week = $288

Now, 4 % of her total sales = $288

or, 4% of ($m) = $288

⇒ $\frac{4}{100} \times m = 288$

or, $m = \frac{288 \times 100}{4} = 7,200$

⇒ m = $7,200

Hence, the total amount of her weekly stock sales = $7,200

b) Let us assume that the total amount of her sales in a year = $k

The total amount of commission earned = $14,000

Now, 4 % of her total sales = $14,000

or, 4% of ($k) = $14,000

⇒ $\frac{4}{100} \times k = 14,000$

or, $k = \frac{14,000 \times 100}{4} = 350,000$

⇒ k = $350,000

Hence, the total amount of her yearly stock sales = $350,000

Question text You have just won the lottery. The Lottery Corporation offers you two options: 1. a lump-sum payment of $400,000,

igomit [66]

Use present value equation.
If present value of annuity equals 400,000, then you are indifferent.

$PV = A(v + v^2 + ...v^{20}) \\ \\ PV = A\frac{v(1-v^{20})}{1-v}$

where v = 1/(1+r) and A = annual payment = 800,000/20 = 40,000

PV = 400,000
After subbing in the numbers, the equation is:
$10 = \frac{v(1-v^{20})}{1-v} \\ \\ 10 - 10v = v - v^{21} \\ \\ v^{21} - 11v+10 = 0 \\ \\ v = 0.928034 \\ \\ \frac{1}{1+r} = 0.928034 \\ \\ r = 0.0775$

Therefore at interest rate of about 7.75% you are indifferent.
