Answer:no
Step-by-step explanation: No, because all the ratios of y to x are not equal.
It would be 0.06 so 6 cents
1. first parabola is up, so a are going to be positive
y = a(x-r)(x-s),
roots -7,-3, so we can write y=a(x+7)(x+3) [1]
we can take point (-5,-2), substitute into equation [1], and find value of a
-2=a(-5+7)(-5+3)
-2=a*2*(-2)
a=1/2
so first parabola has an equation
y=1/2(x+7)(x+3)
2. second parabola
y=a(x-r)(x-s) roots are 2 and 4 so we ca write
y=a(x-2)(x-4) take point (3,4) and substitute into this equation
4 =a(3-2)(3-4)
4=-a
a=-4, and it will look down
y=-4(x-2)(x-4)
This is a decay problem,
The equation is written as start value x (1 - rate)^tike
Using the information given in the problem:
a) Total = 120(1-0.12)^Hours
b) Replace hours with 19 and solve:
Total = 120(1-0.12)^19
Total = 120(0.88)^19
Total = 10.57674 mg
Round the answer as needed.
Answer:
point d
Step-by-step explanation:
-5/2 = -2.5 and -6/3 = -2
