Answer:
117.36
Step-by-step explanation:
You would have to multiply 65.2 times 1.8
Answer:
A) x = 2, x = 7
Step-by-step explanation:
x^2 + 14 = 9x
Subtract 9x from each side
x^2-9x + 14 = 9x-9x
x^2-9x + 14 = 0
What 2 numbers multiply to 14 and add to -9
-7*-2 = 14
-7+-2 = -9
(x-7)(x-2) = 0
Using the zero product property
x-7 = 0 x-2 =0
x=7 x=2
Answer:
slope: -1/2
Y-intercept: -1
Step-by-step explanation:
Get Y by itself by subtracting x on both sides
2y= -x -2
Now divide both sides by 2 to cancel the two connected to the y:
Y = -1/2x -2/2
So y= -1/2x -1
Y=mx+b so m is the slope and b represents the y-intercept
The number of bacteria at any time t where t is number of hours is given by the equation,
At = Ao(1/2)^t/4
where Ao is the original number of bacteria. Substituting the known values from the equation,
1500 = (75000)(0.5)^t/4
The value of t from the equation is equal to 22.57 hours.
