Answer:

D. Amount of income earned and years of education

Step-by-step explanation:

A positive correlation is a linear movement where when one variable increases, another variable increases as well.

Shoe size and weight have correlation.
Day of the week and temperature also have no correlation.
Cost to heat a house and putside temperature would be a negative correlation because on variable is decreasing while the other is increasing.
The longer your education, the more your income will make because of your knowledge on that particular subject.

Therefore, the best answer is D.

hope this helps!

An airplane takes off from an airport. When the

Ivanshal [37]

The angle of elevation is = 70° and the distance the airplane travelled in the air is = 17,557ft

<h3>Calculation of the distance travelled</h3>

To calculate the angle of elevation of the airplane

tan x° = opposite/adjacent

where opposite = 16,500 feet

adjacent = 6,000 ft

tan x° = 16,500 / 6,000

tan x° = 2.75

X = arctan ( 2.75)

X = 70°

To calculate the distance the airplane travelled in the air Pythagorean Theorem is used.

C² = a² + b²

C² = 16,500² + 6,000²

C² = 272250000 + 36000000

C² = 308250000

C= √308250000

C= 17,557ft

Answer + Step-by-step explanation:

$\frac{5^{10}}{5^{5}} =5^{10-5} = 5^5$

$\text{used property :} \ \ \ \frac{a^{m}}{a^{n}} =a^{m-n}$

_______________________

$(4^8)^3 = a^{8 \times 3}=a^{24}$

$\text{used property :} \ \ \ (a^n)^m = a^{n \times m}$

$10^{-4}=\frac{1}{10^{4}} \ \text{not} \ \frac{1}{4^{10}}$

_______________________

15⁶ × 15³ = 15⁶⁺³ = 15⁹

<u>Recall</u> : If a ≠0 ⇒ a⁰ = 1

Then

Since 6⁸ ≠ 0 ⇒ (6⁸)⁰ = 1

Is it possible that the image of a point after a reflection could be the same point as the preimage?

Vera_Pavlovna [14]

Yes, it is possible. For example, let's say that point A is (0,4) and there's a reflection over the y-axis, then point A would still be (0,4).
