Which set of coordinates represents the reflection of the following image over the y–axis?


A
(–6 , 2), (–4 , 8), (–2 , 2)

B
(6 , 2), (4 , 8), (2 , 2)

C
(–6 , –2), (–4 , –8), (–2 , –2)

D
(–2 , 2), (0 , 8), (2 , 2)

Answer:

AB = 21

Step-by-step explanation:

the line EB is parallel to the side of the triangle DC and intersects the other 2 sides proportionally , that is

[tex]\frac{AE}{ED}[/tex] = [tex]\frac{AB}{BC}[/tex] ( substitute values )

[tex]\frac{14}{12}[/tex] = [tex]\frac{AB}{18}[/tex] ( cross- multiply )

12 AB = 14 × 18 = 252 ( divide both sides by 12 )

AB = 21

Using the Pythagorean Theorem, it is found that the group will have to travel 90 miles.

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

In this problem:

[tex]d^2 = 25^2 + 60^2[/tex]

[tex]d = \sqrt{25^2 + 60^2}[/tex]

d = 65.

The total distance is given by:

Td = 25 + 65 = 90 miles.

Answer:

[tex]-\frac{2}{3} x[/tex]

Step-by-step explanation:

Hey there!

To find slope, you take [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

In this case

y2: 6

y1: 4

x2: -3

x1: 0

Now we plug in this information

[tex]\frac{6-4}{-3-0} \\\\\frac{2}{-3} \\\\-\frac{2}{3}[/tex]

Since this is the slope, you have to add a "x"

So, the slope is [tex]-\frac{2}{3} x[/tex]

explanation:

percent. part

_______ = _____

100. whole

42. ?

____ = ____

100. 800

cross multiply

800×42=33,600

then divide by 100

33,600/100=336

Answer:

336

Step-by-step explanation:

If 42% said they shopped online last week, that means the number of people who said they shopped online last week is 42% of 800. "Of" just means we should multiply, and since 42% = 42/100 (since % is just /100), we can use the following to find the answer (I used cross multiplication to simplify):

42          800         42         8

---    *               =     ----    *       =     336

Answer:

D. (x^3 - 10)(x^2 + 10x^3 + 100).

Step-by-step explanation:

Using  the identity a^3 - b^3 = (a - b)(a^2  + ab + b^2):

We have  x^9-1000 :

- here a = x^3 and b = 10 so:

x^9-1000 = (x^3 - 10)(x^2 + 10x^3 + 100)

Answer: 93

Step-by-step explanation:

The probability that the company will have to pay at least $150,000 in benefits next year is 0.047 if the there are 120 women.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

The probability of dying:

P(dying) = 1/150

P(living) = 1 - P(dying) = 1 - 1/150 = 140/150

There are 120 women.

P(x≥3) = 1 - [P(x=0) +P(x=1) + P(x=2)]

[tex]\rm P(x\geq 3)=1-[(120 \ choose \ 0)(1/150)^0)((149/150)^{120})+[/tex]  

                  [tex]\rm (120 \ choose \ 1) ((1/150)^1) ((149/150)^{119}) +[/tex]

                  [tex]\rm (120 \ choose \ 2)((1/150)^2)((149/150)^{118})][/tex]

P(x≥3) = 0.047

Thus, the probability that the company will have to pay at least $150,000 in benefits next year is 0.047 if the there are 120 women.

Answer:

first one is the correct answer

Answer:

Step-by-step explanation:

In order to solve this, you must use the distributive property.

[tex]\sf{\dfrac{4\left(5t+1\right)}{5}}[/tex]

Distributive property:

⇒ A(B+C)=AB+AC

⇒ 4(5t+1)

Multiply by expand.

4*5t=20t

4*1=4

Rewrite the problem down.

20t+4

20t+4/5

[tex]\text{FRACTION RULES: }\\\\\\\Longrightarrow: \sf{\dfrac{A\pm \:B}{C}=\dfrac{A}{C}\pm \dfrac{A}{C}}[/tex]

[tex]\Longrightarrow: \sf{\dfrac{20t+4}{5}=\dfrac{20t}{5}+\dfrac{4}{5}}[/tex]

You have to divide the numbers from left to right.

⇒ 20/5=4

[tex]\Longrightarrow: \boxed{\sf{4t+\dfrac{4}{5} }}[/tex]

Answer:

[tex]4t + \frac{4}{5}[/tex]

Step-by-step explanation:

Step 1:  Distribute

[tex]\frac{(4 * 5t) + (4 * 1)}{5}[/tex]

[tex]\frac{20t + 4}{5}[/tex]

c) 0.025

d) [tex]f(x)=2950000(0.975)^x[/tex]

e) 2,409,123

Step-by-step explanation:

Part (a)

Exponential DECAY, since the population was decreasing annually.

Part (b)

Initial amount = 2,950,000 people (in the year 2000)

Part (c)

Decay factor = 2.5% = 0.025 (in decimal form)

Part (d)

General form of exponential decay function:

[tex]f(x)=a(1-r)^x[/tex]

where:

Given:

[tex]\implies f(x)=2950000(1-0.025)^x[/tex]

[tex]\implies f(x)=2950000(0.975)^x[/tex]

Part (e)

To determine the city's population in 2008:

[tex]x = 2008 - 2000 = 8[/tex]

Answer:

It takes 3 hours for the train to be 600 Miles apart

Answer:

16

Step-by-step explanation:

The figure shown is a trapezoid

Area of a trapezoid = 1/2(bottom base length + top base length) × height

Bottom base length = 7 units

Top base length = 1 unit

Height = 4 units

So area = 1/2 ( 7 + 1 ) × 4

==> add 7 and 1

Area = 1/2 (8) × 4

==> multiply 1/2 and 8

Area = 4 × 4

==> multiply 4 and 4

Area = 16

The sampling strategy she use was a quota.

Quotas are meant to establish boundaries on the number of specific goods that are allowed to be lawfully imported into the country throughout a distinct period of time. In that, quotas are similar embargoes, except quotas don´t have explicit political purposes as embargoes do.

A Fixed quota would be a maximum amount not to be surpassed, while a tariff rate surcharge allows it, but with a higher duty.
