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

**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.

WILL GIVE BRAINLIEST! Form quadratic functions given the following information: f(x)>0 if and only if 1

**Answer:**

**Step-by-step explanation:**

sin (330)

-4 cot

(-45)

csc (60)

**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]

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.

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:**

Yes

Two variables may be associated without a causal relationship. For example, there is a statistical association between the number of people who drowned by falling into a pool and the number of films Nicolas Cage appeared in in a given year. However, there is obviously no causal relationship.
