Answer:
There is 1 solution
Step-by-step explanation:
y = -3 (x+1) ^2
Using the zero product property
0 = -3 (x+1) ^2
Divide by -3
0 = (x+1) ^2
Take the square root of each side
sqrt(0) = sqrt( (x+1) ^2)
0 = x+1
Subtract 1 from each side
-1 =x
There is 1 solution
The answer is going to be 3.5 more than 52.5 so the answer is 56.
Answer:
20ln(3)
Step-by-step explanation:
Put 15 for A and solve for t.
15 = 45e^(-.05t)
15/45 = 1/3 = e^(-.05t) . . . . divide by 45
ln(1/3) = -.05t . . . . . . . . . . . take natural logs
20ln(3) = t . . . . . . . . . . . . . . multiply by 20, simplify
It will take 20·ln(3) years for the area to decrease to 15 km^2.

Answer:
AB and CD would be 30
AC and BD would be 16
Step-by-step explanation:
The scale factor is what you multiply the sides by. Dilate means wider or larger so you multiply each side by the scale factor of 2 to get the higher scaled rectangle.
