Answer:

Step-by-step explanation:

2 || 1 - 4 6 - 4

2 -4 4

==================

1 -2 2

x^2 - 2x + 2 with no remainder.

Looks like the answer is B

Note: Note that the two in x - 2 changes sign. That always happens when using synthetic division as long the number in front of the x is positive.

An engineer is trying to design a runway for an airport. He knows that airplanes have the ability to accelerate at 3.3 m/s ^ 2 a

chubhunter [2.5K]

Answer:

The proposed 1600 meters runway length is not long enough

Step-by-step explanation:

The given parameters are;

The amount by which a plane can accelerate = 3.3 m/s²

The time it takes for a plane to lift off the ground = 35 seconds

The length of the runway on the blueprint = 1,600 meters

Therefore, from the equation of motion for distance traveled, s, acceleration, a, and time taken, t, we have;

s = u·t + 1/2·a·t²

Where;

u = The initial velocity

t = 35 seconds

a = 3.3 m/s²

Given that all planes will start motion from rest, we have;

u = 0 m/s

Therefore;

s = 0 × 35 + 1/2 × 3.3 × 35² = 2021.25 meters

Which indicates that the length of the runway a plane would need for take off should be at least 2021.25 meters long, therefore, the blueprint's 1600 meters runway length is not long enough.

Find the sum of the interior angle measures of the green polygon,

Radda [10]

Answer:

The sum of interior angles of given polygon is 900°

Step-by-step explanation:

A regular polygon is a n-sided figure with n sides and the length of all sides is same.

In the diagram, we have a polygon with 7 sides.

The formula given is used to calculate the sum of interior angles of a polygon

$Sum\ of\ interior\ angles = (n-2)*180$

Here n is the number of sides of polygon

In the given polygon

n = 7

So,

$Sum = (7-2)*180 = 5*180 = 900$

Hence,

The sum of interior angles of given polygon is 900°

Please help i will give 30 points

grigory [225]

Answer:

Step-by-step explanation:

The area would have been 80*x=1600.

that means x=60. So, two pennant bases are 60.

That means one pennant base is 30.
