17) Sometimes true

Given only that a quadrilateral is a parallelogram, we can only conclude the opposite sides are congruent - not the adjacent sides

18) Always true

Adjacent angles of a parallelogram are supplementary.

19) Always true.

Opposite sides of a parallelogram are congruent.

20) Never true

Diagonals of a parallelogram bisect each other, meankng that MR = RP.

An airplane is flying at an altitude of 10,000 ft. The airport at which it is scheduled to land is 50 miles away. Find the avera

Vinil7 [7]

Answer:

The average angle at which the airplane must descend for landing is 21°

Step-by-step explanation:

Here, we have question related to angle of elevation and depression

The height of the airplane be, y = 10,000 ft

The Location of the airport is, x = 50 miles = ‪26400 ‬ft

Therefore,

we have,

Let the average angle be θ

Therefore,

$tan \theta = \frac{y}{x} = \frac{Opposite}{Adjacent}$

The opposite to the angle of descent is the height and the adjacent is the distance of the airport away from the airplane

Therefore, tan θ = $\frac{10000}{26400} = 0.379$

Therefore, the average angle θ = tan⁻¹ 0.379 = 20.746 ° ≈ 21°.

Can u plz help me answer question 30

slamgirl [31]

We are given:

$3x^3-2x^2$

There seems to be nothing I can do to simplify this equation. However, I can factor out an $x^2$ since they both have at least an $x^2$ . Here is what we get:

$x^2(3x-2)$

This is in the simplest form I can get into. I cannot do anything more to simplify this expression. This is your final answer.

The function f (t) = 12(1 +0.03) can be used to determine the population, in thousands of a town t years

Alja [10]

f= the original amount of people, a steady growth throughout the years

t=time

In 1955 the population was 12 thousand. Compared to the current population of 12.36 thousand, the population then was roughly 77%.
