Answer:
48 units
b= 48 units
Step-by-step explanation:
pythag is
we have a and c
so substitute them in
now you can solve

subtract 196 from both sides
subtract
2500 - 196 = 2304
solve for the square root
square root of 2304= 48
therefore b= 48 units
Answer:
(–19, 55)
Step-by-step explanation:
y = –3x – 2 equation 1
5x + 2y = 15 equation 2
using equation 1 in equation 2 we have:
5x + 2(–3x – 2) = 15
5x –6x – 4 = 15
-x = 15+4
x=-19
using equation 1:
y = -3(-19)- 2
y= 57-2
y= 55
Answer:

Step-by-step explanation:
By definition, we can write ln instead of log. WHEN??
Whenever the base of the logarithm is the number "e".
Hence, when we have:

We can write it in shortcut as:

Hence, ln x can also be written as 
Fourth answer choice is right.
Yeah that is correct. 3/4 is equal to .75
