Angelina_Jolie [31]

Answer:

  8184 vocalists sang in total

Step-by-step explanation:

The number needed is ...

  8 + 16 + 32 + 64 + 128 + 256 + 512 + 1024 + 2048 + 4096

You can add these up to get a total of 8184, or you can use the formula for the sum of a geometric series:

  Sn = a1(r^n -1)/(r -1) . . . . where a1 is the first term and r is the common ratio

  S10 = 8(2^10 -1)/(2 -1) = 8(1024 -1)/1 = 8184

Will give brainliest to correct answer.

Use Pythagorean's Theorem to find the length of x.  30^2-16^2=x^2  so  900-256=x^2  and  x= \sqrt{644}.  We can simplify that radicand down into a perfect square times a prime number, and that is \sqrt{4*161}.  4 is a perfect square that can be pulled out as a 2, so the length of x is 2 \sqrt{161}, the choice on the top right.

Consider functions f and g below.
Pani-rosa [81]

Answer:

D

Step-by-step explanation:

f(x) - g(x) = -9x^2 - 7x + 12 - (3x^2 - 4x - 15)  Remove the brackets

f(x) - g(x) = -9x^2 - 7x  + 12 - 3x^2 + 4x + 15

f(x) - g(x) = -9x^2 - 3x^2 - 7x + 4x + 12 + 15

f(x) - g(x) = -12x^2- 3x + 27
