In the distance, an airplane is taking off. As it ascends during take-off, it makes a slanted line that cuts through the rainbow

irakobra [83]

Answer:

The equation of the parabola is given to be : y = -x² + 36

So, the airplane will cut the rainbow if the graph of the equation of airplane intersects the graph of rainbow.

Now, to find the equation of airplane :

The points through which airplane passes are : (1,0) and (0,2)

⇒ Equation : 2x + y = 2

This equation will intersect the parabola at exactly two points.

And the points are the solution of these two equation :

(-4.916,11.832) and (6.916,-11.832)

The required table is :

x -4.916 11.832

y 6.916 -11.832

If you walked all three trails in one day, how far would you walk? Write the answer in meters and kilometers

nordsb [41]

Answer:

a. Central Park 2.542 km, Marine Park 1.28 km, Van Cortlandt Park 2.30 km

b. 6.122 km

Further explanation

Given:

Van Cortlandt Park’s walking trail is 1.02 km longer than Marine Park’s.

Central Park’s walking trail is 0.242 km longer than Van Cortlandt’s.

Question a. Fill in the missing information in the chart below.

Central Park ____ km

Marine Park 1.28 km

Van Cortlandt Park ____ km

Problem solving:

From the information above, only Marine Park's walking trail has known at 1.28 km.

Because Van Cortlandt Park’s walking trail is 1.02 km longer than Marine Park’s, then we must add the Marine Park's with 1.02 km to get the Van Cortlandt Park's.

Van Cortlandt Park's walking trail = 1.28 km + 1.02 km

Thus, Van Cortlandt Park's walking trail is 2.30 km.

Next, we find out walking Central Park.

Because Central Park’s walking trail is 0.242 km longer than Van Cortlandt’s, then we must add the Van Cortlandt’s with 0.242 km to get the Central Park's.

Central Park's walking trail = 2.30 km + 0.242 km

Thus, Central Park's walking trail is 2.542 km.

Question b. If a tourist walked all 3 trails in a day, how many kilometers would he or she have walked?

Problem solving:

We have to add up the entire walking trail.

Central Park 2.542 km

Marine Park 1.28 km

Van Cortlandt Park 2.30 km

2.542 km + 1.28 km + 2.30 km = 6.122 km

If a tourist walked all 3 trails in a day, he or she would travel a distance of 6.122 km.

What are the first five terms in the<br> recursive sequence defined by the<br> following?

kolezko [41]

The first five terms of the sequence are {0, -1.4, -2.8, -4.2, -5.6}

<h3>Recursive function</h3>

Given the nth term of a recursive expression shown below

an =an-1 - 1.4

where

an-1 is the preceding term

a1 is the first term

an is the nth term

an-1 is

Given the following

a1 = 0

For the second term a2

a2 = 0 - 1.4

a2 = -1.4

For the third term a3

a3 = -1.4 - 1.4

a3 = -2.8

For the fourth term a4

a4 = -2.8 - 1.4

a4 = -4.2

For the fifth term a2

a5 = -4.2 - 1.4

a5 = -5.6

Hence the first five terms of the sequence are {0, -1.4, -2.8, -4.2, -5.6}

Difference of Squares gives which complex factors for the expression x² +11?

77julia77 [94]

Answer:

Step-by-step explanation:

Discussion

i has to appear somewhere. That lets D and B out. They are both wrong.

C has only one i. It can't be right either. You need 2 i-s which will multiply to +1 when squared. That leaves you with a.

The way a is written, it can't be the answer either. For one thing, that 2 makes the answer question at best.

I would say there is no correct answer. Could you check the question? Also it would be a good idea to ask your instructor how this works, in case I'm wrong.
