Remember that you cannot take the log of a negative number, regardless of the base. Also, you can take the logarithm of zero, since no number raised to a power can equal zero (although it come very close). 

Therefore, (x+3), the number inside the logarithm, must be greater than zero. 

x+3 > 0
x > -3 
The domain is x > -3,
or (-3, ∞) in interval notation

Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles. C = 71°, a = 27, c = 26
guajiro [1.7K]

We have

SinC/ c  = Sin A / a

Sin 71/ 26 = Sin A / 27

Sin A  = 27 Sin 71 /  26  = about .982

So°

Sin-1(.982)  = A  = 79. 08°

Then angle B = 180 - 71 - 79.08 = 29.92°

And b is given by

b/sin29.92  = 26/sin 71

b = 26sin29.92/sin71 =  about 13.72

But A could also be an obtuse angle = 180 - 79.08 =  100.92°

So we have

B = 180 - 71 - 100.92 = 8.08°

And we have

b / sin 8.08  = 26/sin71

b = 26sin8.08/sin 71 = 3.865

Find f(-2) for f(x)=3•2^x
8_murik_8 [283]

Answer:

0.75 or 3/4

Step-by-step explanation:

f(-2) = 3•2^-2

f(-2) = 3•0.25

f(-2) = 0.75 or 3/4

Hope this helps! :)

A tour group with 44 people in it is getting rooms in a motel to stay in for the night. no more than 5 people can stay in each r
Anna11 [10]
Hello! 

Since we want to find out how many rooms will be needed for 44 people, we must use division. 

44 ÷ 5 = 8.8

Check by multiplying: 

5 × 8 = 40

Because 40 is less than the amount of people (44), we'll need to multiply by the next number in line (9): 

5 × 9 = 45 (1 extra person, no biggie!) 

The tour group will need 9 rooms.
