Answer:69.66

r=9 so diameter is 18, and the shape being a square you do 18 x 18 = 324

What is the range of y=log^2(x-6)
Marysya12 [62]

Answer:

y\geq 0 or [0, \infty)

Step-by-step explanation:

By definition the function

y = log (x) has a domain of x> 0.

Since the function is not defined for the values of x negative or equal to zero.

The range of this function is all the real numbers.

Since y when 0 and y\geq0 when 1\leq x

In this case we have the function y = log ^ 2 (x-6)

Therefore since the log function is squared then its range is now y\geq 0

Find BC to the nearest tenth. Does anyone know how to do this? I rlly need it now pls.

Answer:

  41.4

Step-by-step explanation:

The Law of Cosines tells you ...

  a² = b² +c² -2bc·cos(A)

where sides a, b, c are opposite angles A, B, C, respectively. Filling in the given numbers, you have ...

  a² = 30² +26² -2·30·26·cos(95°)

  a² ≈ 1711.96

  a ≈ √1711.96 ≈ 41.38

The length of BC is about 41.4 units.

23% of 432 students equals how many students?
irga5000 [103]
Multiply 23% by 432.
change 23% into a decimal which simply is 0.23
0.23*432=99.36
since it's students, and u can't have part of a student round it off and say 99 students.
