The equatorial radius of the planet Mars:
r = 3.396 km
An arc of the planet that is visible to a camera in a satellite:
cos Ф/2 = r / ( r + 12,000 ) = 3.396 / ( 3,396 + 12,000 ) =
= 3,396 : 15,396 = 0.22
Ф/ 2 = cos^(-1) 0.22 = 77.3°
Ф = 2 · 77.3° = 154.6°
Answer: 154° 36

Drag the tiles to the boxes to form correct pairs. Not all tiles will be used.
kolezko [41]

Answer:

Please see attached image

Step-by-step explanation:

We can work on the products of binomials using distributive property to multiply every term of the first binomial by every term of the second one. Finally combine like terms to get the trinomial that results:

1) (2+a)(2+a)=4+2a+2a+a^2=4+4a+a^2

2) (2a+1)(2a+1)=4a^2+2a+2a+1=4a^2+4a+1

3) (2a-1)(2a-1)=4a^2-2a-2a+1=4a^2-4a+1

4) (2-a)(2-a)=4-2a-2a+a^2=4-4a+a^2

Pls help I’ll give you 25 points
Nezavi [6.7K]

Answer:

For the 1st row:

6.38 - 6 19/50 - 638%

Step-by-step explanation:

I would suggest using MathPapa if you are trying to do it quick. MathPapa will only really help with finding fractions and percentages, though. To get the decimal, need to find percentages then move decimal to the left 2 times.

ex. 125% -> 1.25

I hope this helps! Have a blessed rest of your night!

Prove that the inequality (a+1)·(a+1)>(a−1)·(a−1) is not true for some values of a.
Effectus [21]

Explanation:

Consider the case a = -1. Then the expression becomes ...

  (-1+1)(-1+1) > (-1-1)(-1-1) . . . . test case

  0·0 > (-2)(-2) . . . . . simplified a bit

  0 > 4 . . . . . . . . NOT TRUE

_____

If we subtract the right side from both sides, the inequality becomes ...

  (a+1)(a+1) -(a-1)(a-1) > 0

  a² +2a +1 -(a² -2a +1) > 0

  4a > 0

  a > 0

The inequality is only true for positive values of "a". For a ≤ 0, the inequality will not be true.
