Step-by-step explanation:
f(x) =(x-5/2)^2-9/5
A=(1,2) and b=(2, - 1) . Find 4a - 3b
1st carry out the scalar multiplication 4a and -3b
4a =[4(1) , 4(2) ] = (4 , 8)
-3b = [-3(2) . -3(-1)] = (-6 , +3)
4a - 3b = [(4-6) , (8+3)] = (-2 , 11)
Answer: The geometric mean of 125 and 5 is 25
The age of Jennifer is 16.
<h3>What is Jennifer's age?</h3>
Let Jennifer's age be represented with x
Jonathan's age would be 2x
The sum of their ages would be 48
2x + x = 48
3x = 48
x = 48 /3 = 16
