Answer:
The roots of the equation is real and repeated
Step-by-step explanation:
Here, we want to describe the nature of the roots of the given quadratic equation
To get the nature of the roots, we find the discriminant of the equation
The discriminant is;
b^2 - 4ac
In this case, b = -28 , a = 49 and c = 4
The discriminant is thus;
-28^2 - 4(49)(4)
= 784 - 784 = 0
Since the discriminant is zero, this means that the quadratic equation has real roots which are the same
Answer:
This is a geometric sequence. The first term is the max height of the first curved path, which is 0.5. The second one is 52% of that meaning that it is 0.52 times the first term. The third term is 0.52 times the second term. Thus, in this geometric sequence,
Step-by-step explanation:
a = 0.5
r = 0.52
You will need to use the relation a_n = a \cdot r^{n-1}
Answer:
7,500 was the attendance before the drop.
Step-by-step explanation:
3750 x 2
It grows by 10% each year. multiply the number by 0.1, then add. so 0.1×2420 is 242. add 242+2420=2662.
short answer:
this years tuition is $2662.
next years tuition is $2928.
