That means f(x)=kx²
so
f(5)=75=5²k
solve for k
75=5²k
75=25k
divide by 25
3=k
f(x)=3x² is da equation
so
f(4)=3(4)²
f(4)=3(16)
f(4)=48
C is answer
Answer:
The range consists of all real numbers greater than and equal to -8
y >= -8
Step-by-step explanation:
The range of the function f(x)=-3(x+6)2-8 is ?
This is a parabola.
notice it opens upward starting from the vertex (6, -8)
so the range goes from -8 and upward
Answer:
1. 0-9
2. 0-6
3. 0-6
Step-by-step explanation:
This scenario can be simulated by generating a set of three numbers using a number generator with numbers 0-9. The numbers 0-6 would represent couples who prefer indoor weddings. If all three numbers in the set are in the range 0-6, it would mean that all three couples prefer indoor weddings.
(ik you might not need this anymore, but I'm hoping it proves useful to others)
Answer:
One hundred and thirty five
Step-by-step explanation:
fifty percent of ten is five so the new side is fifteen feet. fifty percent of six is three so that new side is nine feet. nine times fifteen is one hundred and thirty five
