To evaluate log3 72, given that log3 8 is approximately 1.8928, we use properties of logarithms. We can express 72 as 8×9, and since log3 9 equals 2, log3 72 is 1.8928 + 2, which is 3.8928.
The student is asking to evaluate log3 72 given that log3 8 ≈1.8928. We can use the properties of logarithms to solve this. Since 72 can be expressed as 8×9, and we know that log3 8, we can find the log3 9 by understanding that 9 is 3²and therefore log3 9 is 2, because the base and the argument are the same.
Now, using the property of logarithms that loga (xy) = loga x + loga y, we can write log3 72 as:
log3 (8 ∙9) = log3 8 + log3 9
log3 72 = 1.8928 + 2
log3 72 = 3.8928

Answer:
The answer is undefined.
Step-by-step explanation:
Slope is found using this equation: y-y1/x-x1. Fill in the coordinates to this equation. It should now look like this. -7--3/-5--5. When subtracting from two negatives, it changes into a positive. For example, -7--3 becomes -7+3, which equals -4. The same thing applies for the second part. -5--5 becomes -5+5, which equals 0. So, your slope is -4/0. However, when a 0 is in the denominator, it becomes undefined. So, the answer is undefined.
Answer:
3 tons
Step-by-step explanation:
B. (F+g)(x)=5+9x
C. (F+g)(x)=15+5x
D. (F+g)(x)=15+9x
Answer:
C
Step-by-step explanation:
To find the sum of f and g then add the expressions f(x) and g(x).
f(x) + g(x)
10-2x + 7x+5
10+5x+5
15+5x
This means that (F+g)(x) = 15+5x.
