Answer:

D. D₂ (∆XYZ)

Step-by-step explanation:

Dₙ = (x,y) → ((n)x, (n)y)

_________________

X = (-1, 2).

Y = (2, -1).

Z = (-2, -1).

_________

Dₙ ∆XYZ:

X(-1, 2) → X'(-2, 4)

Y(2, -1) → Y'(4, -2)

Z(-2, -1) → Z'(-4, -2)

______________

-2 / -1 = 2, 4 / 2 = 2.

4 / 2 = 2, -2 / -1 = 2.

-4 / -2 = 2, -2 / -1 = 2.

_______________

D₂ = (x,y) → ((2)x, (2)y).

X(-1, 2) → ((2)(-1), (2)(2)) = X'(-2, 4)

Y(2, -1) → ((2)(2), (2)(-1)) = Y'(4, -2)

Z(-2, -1) → ((2)(-2), (2)(-1)) = Z'(-4, -2)

Answer:

1/25

Step-by-step explanation:

Given :

Let :

Y = yellow marbles

P = pink marbles

B = blue marbles

Y = 2 ; P = 3 ; B = 5

Note : selection is done with replacement :

Probability = required outcome / Total possible outcomes

Total possible outcomes = (2+3+5) = 10

Probability of drawing 2 yellow marbles :

First Draw : P(yellow) = 2 /10 = 1/5

Second draw: P(yellow) = 2/10 = 1/5

Probability of drawing 2 yellow marbles :

1/5 * 1/5 = 1 /25

Answer:

Answer:

2/5

Step-by-step explanation:

She completed 8 out of 20 so we divide 8 by 20

8/20 can be simplified if we divide both the numerator and denominator by 4

which equals 2/5

Answer:

2/5

Step-by-step explanation:

8 divided by 20 gives you .4 which is 2/5

Answer:

x² - x - 6

Step-by-step explanation:

Given

(x + 2)(x - 3)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 3) + 2(x - 3) ← distribute parenthesis

= x² - 3x + 2x - 6 ← collect like terms

= x² - x - 6

Answer:    

[tex]x^{2} -x-6[/tex]  

it's quadratic

Answer:

3.49 inches

Step-by-step explanation:

circumference = 2(2)(π) = 12.56 inches

(100/360)(12.56) = 3.49 inches

Answer:

50

Step-by-step explanation:

Answer:

Colin will have $1,265 after three years.

Step-by-step explanation:

First, we find the amount of interest Colin will have by using the following formula,

simple interest = principal * interest rate * time

now that we know the formula, we substitute the numbers in.

simple interest = $1,100 * 5% * 3

since the interest rate is obviously a percentage, we have to convert it into a decimal.

simple interest = $1,100 * 0.05 * 3

now that it is a decimal, we can solve this expression.

simple interest = $1,100 * 0.05 * 3

simple interest = $55 * 3 (here, we did $1,100 * 0.05 first so that it doesn't get confusing with all the numbers, it will be easier with two final numbers)

simple interest = $165

Colin has $165 simple interest but over here asks how much she will have AFTER 3 years. think about it, can you have $165 after having $1,100 in your bank AFTER 3 years? no, so we need to add the interest by the principal by using the following formula,

total amount = principal + simple interest

now, we substitute the numbers in.

total amount = principal + simple interest

total amount = $1,100 + $165

total amount = $1,265  

Therefore, Colin will have $1,265 after 3 years.

Answer:

Answer:

q=-3 2/5

Step-by-step explanation:

First multiply -13 with (q+4)

-13q-52=7q+16

Now you have to change the order before = the numbers with q and after = the numbers without anything

-13q-7q=52+16

Remember that when you change positions the symbol too

Then solve it

-20q=68

Now u have to divide as i do

q=68/-20

you can simplify it

q=3 8/-20

Now divide by the greater divisor in this case is 4

q=3 2/-5

And organize it

q=-3 2/5

Never forget to do q=(answer)

Hopefully it helps.

Answer:

2/5

Step-by-step explanation:

The rate of change is the slope.  The equation is in slope-intercept form.  So, the slope is 2/5 = rate of change

Answer:

Surface area of cylinder = 24π

Step-by-step explanation:

Given:

Base diameter = 4 yd

So Radius = 4 / 2 = 2 yd

Height = 4 yd

Find:

Surface area of cylinder

Computation:

Surface area of cylinder = 2πr(h+r)

Surface area of cylinder = 2π(2)(4+2)

Surface area of cylinder = 2π(2)(6)

Surface area of cylinder = 24π

Answer:

Sample space = (AA, AN, AD, NA, NN, ND, DA, DN, DD) ;

0.556

Step-by-step explanation:

Given :

Possible outcome of each policy statement = (A, N, D)

Number of statements = 2

Sample space = 3² = 9

Sample space = (AA, AN, AD, NA, NN, ND, DA, DN, DD)

Probability that a person agrees with atleast one of the 2 policy statements :

Probability = required outcome / Total possible outcomes

Required outcome = (AA, AN, AD, NA, DA) = 5

HENCE, P(person agrees with atleast one of the 2 policy statements) = 5 /9 = 0.556

Wasp, any member of a group of insects in the order Hymenoptera, suborder Apocrita, some of which are stinging. Wasps are distinguished from the ants and bees of Apocrita by various behavioral and physical characteristics, particularly their possession of a slender, smooth body and legs with relatively few hairs.
