Answer:
18
Step-by-step explanation:
f(x) = 2(1/3)^x
[x = -2]
f(-2) = 2(1/3)⁻²
= 2(9)
= 18
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.
(1 2/3) / 50 = x/60
cross multiply
50x = 60 * 5/3
50x = 100
x = 100/50
x =her walking pace is 2 miles per hr
The measure of angle VUT is 65°. You get the answer by finding the angle of VTU and to do that you subtract 180 from 115, which gets you the angle for VTU.
The answer is 828282827337829245902637
