Answer:

Similar polygon

Step-by-step explanation:

If two polygon similar then the ratio of the corresponding sides is the scale factor.
All interior angles are congruent.

That's a copy of the figure from the other post; I didn't look at the answer.

We have Start(0,0)

$A(-16.55\cos 25, -16.55 \sin 25)$

$B=A+(5 \cos 53, 5 \sin 53)$

$C=B+(20,0)$

$C=(-16.55\cos 25 + 5 \cos 53+20, -16.55 \sin25 - 5 \sin 53)$

$C \approx (8.00968, -10.9875) \approx(8,-11)$

Your team takes the direct path at a constant speed of 6 miles per hour.

Our team. $T=\sqrt{8^2+11^2}/6 = 2.27 \textrm{ hours}$

Team Red follows the riddle and travels at 8 mph from Start to Post A, 9 mph from Post A to Post B, and 11 mph from Post B to Finish.

$T=16.55/8 + 5/9 + 20/11 = 4.44 \textrm{ hours}$

Team Blue follows the riddle and travels at a constant speed of 10 mph.

 $T=(16.55 + 5 + 20)/10 = 4.155 \textrm{ hours}$

Team Yellow follows the riddle and travels at a constant speed of 11 mph, but stops at Post A for 30 minutes and stops again at Post B for another 30 minutes.

$T=(16.55 + 5 + 20)/11 + 30/60 + 30/60=4.78 \textrm{ hours}$

Winner: our team, then Blue, then Red, then Yellow

What is the answer please help

Answer:

B: 22.5 degrees

Step-by-step explanation:

The interior angles of a pentagon add up to 540 degrees

(if you dont believe me you can turn a pentagon into three triangles, 3x180 = 540)

So you have four same angles say measure "x" degrees, and one final one that measures "5x" degrees, so 9x = 540, and x = 60

Unless I read the problem wrong, 60 degrees is the answer which is not an option :P

Edit: Yea I read it wrong, the final angle is 5 times the other four angles COMBINED, so that angle measures "20x" degrees.

The total would be 24x = 540, and so x = 22.5

How does a quadratic function differ from that of a linear or exponential

salantis [7]

Hello,

A linear function is a polynomial function of degree 1
(1,2,3,4,5,6,....)
A quadratic function is a polynomial function of degree 2
(1,4,9,16,25,49,64,81,...)
A exponential function is not a polynomial function (we may imagine a infinity degree)
(1,2,4,8,16,32,64,128,256,512,1024,...)

I really need help!!!!!! 25 points!!

SCORPION-xisa [38]

Answer:

1. 9/25 units^2

2. s = 1/4 unit

3. = 8/27 units^3

4. s = 3/4 unit

Step-by-step explanation:

1. The area of a square is A=s^2

A = (3/5)^2

= (3/5) *(3/5)

= 9/25 units^2

2. The area of a square is A=s^2

1/16 = s^2

Take the square root of each side

sqrt(1/16) = sqrt(s^2)

1/4 = s

s = 1/4 unit

3. The volume of a cube is V = s^3

V = (2/3)^3

= (2/3) (2/3) (2/3)

= 8/27 units^3

4.The volume of a cube is V = s^3

27/64 = s^3

Take the cube root of each side

(27/64)^(1/3) = (s^3)^(1/3)

3/4 = s

s = 3/4 unit
