Answer:
11
Step-by-step explanation:
z = 2; therefore, f(z) = f(2).
The letter/number inside of the bracket replaces the orginal letter, in this case w.
f(w) = 2w^3 - 5
f(2) = 2(2)^3 - 5
f(2) = 2(8) - 5
f(2) = 16 - 5
f(2) = 11
As a result, f(z) = 11
Answer:
a)2,6,12,14
Step-by-step explanation:
Given:
The ratio of the amount of money Kate has to that of Nora is 3 : 5.
After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9.
To find:
The sum of money Kate had initially.
Solution:
Let the initial amount of money Kate and Nora have are 3x and 5x respectively.
After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9.
The amount of Kate = 3x+150
The amount of Nora = 5x-150
Now,
Divide both sides by 8.
Putting x=300 in 3x, to get the amount of money Kate has initially.
Therefore, the Kate initially had $900.
