Answer:
(1/2)z
Step-by-step explanation:
To justify the yearly membership, you want to pay at least the same amount as a no-membership purchase, otherwise you would be losing money by purchasing a yearly membership. So set the no-membership cost equal to the yearly membership cost and solve.
no-membership costs $2 per day for swimming and $5 per day for aerobic, in other words, $7 per day. So if we let d = number of days, our cost can be calculated by "7d"
a yearly membership costs $200 plus $3 per day, or in other words, "200 + 3d"
Set them equal to each other and solve:
7d = 200 + 3d
4d = 200
d = 50
So you would need to attend the classes for at least 50 days to justify a yearly membership. I hope that helps!
Answer:
the answer is 12 gallons
Step-by-step explanation:
make fractions improper:
9/8 and 25/2
make them have a common denominator:
9/8 and 100/8
to make a whole gallon but what you do to one side you do to the other:
9/8-1/8=8/8
100/8-1/8=99/8
divide 99/8:
12.375
round down:
12
The equation of the function g(x) will be g(x) = - ln (x + 2).
<h3>What is a logarithm?</h3>
Exponents can also be written as logarithms. A number base logarithm is similar to some other number. It is the exact inverse of the exponent expression.
Let the equation of the function f will be
f(x) = ln x
If the function is multiplied with negative sign, then the function gets flipped about the x-axis.
And if we add 2 in the variable of the function, then the function gets shifted towards left.
Then the equation of the function g(x) will be
g(x) = - ln (x + 2)
