Discriminant = b^2 - 4ac; where a = 1, b = 9 and c = 14
d = (9)^2 - 4(1)(14)
d = 81 - 56
d = 25
the discriminant is greater than zero, so there are two real roots
A]
Exponential function is given by the form:
y=a(b)ˣ
where:
a=initial value
b=growth factor
From the question:
a=$8000, b=1.015,
thus the exponential growth function of this situation is:
y=8000(1.015)ˣ
b] The value of the collection after 7 years will be:
x=7 years
Using the formula:
y=8000(1.015)ˣ
plugging the values we get:
y=8000(1.015)⁷
y=8,878.76
Answer: $8,878.76
Answer:
four of the dogs pounds are 18-19
Step-by-step explanation:
Let's put the statement into Mathematical form first:
It is: 4x - 2x + 15
= 2x + 15
Here, the difference of two output values would be same, so it will be a Linear Equation
