Is √(9+16 ) the same as √(9 ) + √(16 ).

Answers

Answer 1

Answer:

Answer:

Step-by-step explanation:

$√((9+16))$ = $√(25)$ = 5

compared to

$√(9)$ + $√(16)$ = 3 + 4 = 7

Thus

$√((9+16))$ ≠ $√(9)$ + $√(16)$

T is 71 degrees. We know this because the area of a triangle is 180 degrees, you add the angles given 27+82 which equals 109 then subtract that from 180 to find the missing angle “T” 180-109=71

Answer:

71 degrees

Step-by-step explanation:

The angles in a triangle add to 180 degrees, so

∠M + ∠A +∠T = 180

We know ∠M is 82 degrees, and ∠A is 27 degrees, so we can substitute them in.

82+27+∠T=180

109+ ∠T=180 Combine like terms by adding 82 and 27

109-109+ ∠T=180-109 Subtract 109 from both sides to get ∠T by itself

∠T=71

So, the m∠T is 71 degrees

Answer:

1895.22 feet^2

Step-by-step explanation:

So starting off we will find the area of the hexagon.

The formula is complicated so I won’t write it.

The area is 509.22 feet^2.

Now for the triangles.

So the base is 14 feet and the height is 33 feet.

After multiplying them and dividing them by two I got 231 feet^2.

Then multiplying 231 by 6 I got 1386 feet^2.

So adding up 1386 and 509.22 I got 1895.22 feet^2.

In a basketball game, the home team scores (2m+39) points and the away team scores (3m+40) points, where m is the number of minutes since halftime. Who wins the game. What is the difference in the scores m minutes after halftime?

Answers

Answer: The away team will win by m + 1 points

Step-by-step explanation: Minutes can't be negative, so m must either always be positive, or be 0 for a minute then positive for the rest of the game. Therefore, for any positive value m, 3m + 40 will always be greater than 2m + 39. So, the away team will win. To get the difference in points, subtract the two expressions to get m + 1

Write the expression as either the sine, cosine, or tangent of a single angle. sin(pi/2)cos(pi/7)+cos(pi/2)sin(pi/7)

Answers

I will use the sin (a + b) identity:
sin (a + b) = sina cosb + cosa sinb and
here a = π/2 and b = π/7

so sin (π/2 + π/7)
= sin (9π / 14)

Answer:

$\text{sin}((9\pi)/(14))$ .

Step-by-step explanation:

We have been given a trigonometric expression $\text{sin}((\pi)/(2))\text{cos}((\pi)/(7))+\text{cos}((\pi)/(2))\text{sin}((\pi)/(7))$ . We are asked to write our given expression as either the sine, cosine, or tangent of a single angle.
