the form is "y=mx(+/-b). m is slope. b is y-intercept.
Answer:
4 ft by 12 ft
Step-by-step explanation:
x^2 +8x -48
Set this equal to 0 to solve for the values of x
x^2 +8x -48=0
What two values multiply to -48 and add to 8
12*-4 = -48
12+-4 = 8
(x+12) (x-4) = 0
Using the zero product property
x+12 = 0 x-4=0
x=-12 x=4
We cant have a negative length
x=4
The area is 48
48/4 = 12
The other dimension is 12
Answer:
0.85 ( lowest value proportion to vaccinate )
Step-by-step explanation:
Using the herd immunity relationship
Vc = E - ( E / Ro )
Vc = critical vaccination level
E = vaccine effective against the transmission = 1
Ro = Basic reproduction number
lets assume the effectiveness of the transmission = 100% = 1
lets assume the
Vc = 1 - ( 1 / 3 ) = 67%
but the lowest value proportion to vaccinate = 85%
