Answer 1

9514 1404 393

Explanation:

Here is one way to go about it.

Statement . . . . Reason

1. AD ≅ BC, AD║BC, E & F are midpoints of BC, AD . . . . given

2. (1/2)AD ≅ (1/2)BC . . . . multiplicative property of congruence (equality)

3. DF = (1/2)AD, BE = (1/2)BC . . . . definition of midpoint

4. DF ≅ BE . . . . substitution property of congruence

5. BE║DF . . . . segments of parallel lines are parallel

6. BEDF is a parallelogram . . . . BE ≅ DF, BE║DF, definition of parallelogram

Airplanes use radar (radio waves) to measure distances.

The plane is at a height of 5200 m. The airport is 10.2 km away.

How far does the plane need to travel before it lands?


a) 11.4 km

b) 10.4 km

c) 5200 km

d) 10.2 km

Answers

Answer:

10.2 km

Step-by-step explanation:

I thought we have to add 5200 m + 10,2 km, but for this result there is no an alternative. So the correct answer must be 10,2 km, if the plane is right above the airport.

P is inversely proportional to the square of q. When q = 2, P = 12.8 (a) Find a formula for P in terms of q.

Answers

Answer:

P = 51.2/ q

Step-by-step explanation:

Given :

P α 1/q²

P = k/q²

k = constant of proportionality

P = 12.8 ; q = 2

12.8 = k /2²

12.8 = k / 4

k = 12.8 * 4

k = 51.2

Formuka for P in terms of q :

P = 51.2/ q

Answer:

f(x) = -2(x-3)^2+8

Step-by-step explanation:

Using vertex form: f(x)= a(x-h)^2 +k

if the maximum is 8 then k=8

h = 3 --> the midpoint of 1 and 5

Fill in the equation:

f(x) = a(x-3)^2 +8

Using f(1) = 0 to figure out a:

0 = a(1-3)^2+8

4a =-8

a = -2

Our final equation would be[tex]f(x)=-2(x-3)^2+8[/tex]

In standard form:  [tex]f(x)=-2x+12x-10[/tex]
