Answer:
14
Step-by-step explanation:
The coefficient of x² is is a negative 0.6, so this function has a maximum value.
the max value of a quadratic function is the value of f(x) when x=-b/2a,
in this case, a=-0.6, b=382
so x=382/1.2=
r(382/1.2)=-0.6(382/1.2)²+382*(382/1.2)
use a calculator: 60801.67 is the number I got.
Answer:
A = 15 cm^2
Step-by-step explanation:
The area of a triangle is found by
A = 1/2 bh
A = 1/2 (10) * 3
A = 15 cm^2
12x^5 − 15x^3 + 30x^2 If this isn’t the right answer i’m very sorry
Answer:
$60
Step-by-step explanation:
