Answer:
36
Step-by-step explanation:
Since f(x) varies directly with x, f(x) can be expressed alternatively as \[f(x) = k * x\] where k is a constant value.
Given that f(x) is 72 when the value of x is 6.
This implies, \[72 = k * 6\]
Simplifying and rearranging the equation to find the value of k:
k = \frac{72}{6}
Hence k = 12
Or, \[f(x) = 12 * x\]
When x = 3, \[f(x) = 12 *3 \]
Or in other words, the value of f(x) when x=3 is 36
Answer:
x = 0
Step-by-step explanation:
Rewrite (6^2)^x =1 as 6^(2x) = 1.
Next, take the logarithm (common or natural) of both sides, obtaining
2x log 6 = log 1
2x log 6 = 0
Then x = 0.
Note that (6^2)^0 = 1, since any positive number raised to the prower 0 is 1.
Answer: 4 / 663
Step-by-step explanation:
There are 4 queens in a deck of 52 cards.
Probability = 4/52 = 1/13
There are 4 sevens
Probability = 4/51
Total probability = 1/13 x 4/51 = 4 / 663
For this question, all you have to do is subtract 6 from 10 to get 4. 4 + 6 is 10. z = 4.
