Answer:
option 2
f(3+4)
Step-by-step explanation:
To understand this problem, what we can do is solve and compare with the results they give us.
f(x)=a^x f(3) * f(4)
f(3) = a^(3) f(4) = a^(4)
we replace
f(3) * f(4) = a^3 * a^4
as they are powers of the same base
f(3) * f(4) = a^(3+4)
f(3) * f(4) = a^7
Now let's do it with the options they give us
1. f(3^4) f(x)=a^x
3^4 = 81 x = 81
f(81) = a^81 wrong option
2. f(3+4) f(x)=a^x
3+4 = 7 x = 7
f(7) = a^7
correct option
3. f(3*4) f(x)=a^x
3*4 = 12 x = 12
f(12) = a^12 wrong option
Answer: -36a^6+32a^4

Answer:
3.6 qt. and 2.4 qt respectively
Step-by-step explanation:
Let x be x% of 50% saline solution. And (100-x%) be the percentage of 60% saline solution.
54=x*(50/100)+(100-x)*(60/100), solving it we will get x=60%. So we need 3.6 qt. of 50% saline solution and 2.4 qt. of 60% saline solution
Answer:
Step-by-step explanation:
Well first you have:
$15.95 for one sweater
$9.00 each for two shirts
You would double the amount $9.00 which would be:
9 + 9 = 18 or Multiply 9 x 2 = 18
So this would total to 15 + 18 = $33
