Answer:
1093.96
Step-by-step explanation:
900(1+.05)⁴=1093.955625
Since the line goes through (0, 0), it can be described by
y = kx
You are given the point (12, 72), so you know
72 = 12k
6 = k . . . . . . . divide by 12
Then the equation of the line is ...
y = 6x
Answer:
-3.3...
Step-by-step explanation:
3.2p-2.5+2.1p=5p-7/2
3.2p+2.1p-5p=-7/2+2.5
5.3p-5p=-7/2+2.5
0.3p=-1
p=-1/0.3
p=-3.3
Answer:
there is an 8 percent chance
Step-by-step explanation:
The roots of a quadratic equation depends on the discriminant .
- If , the quadratic equation has two real distinct roots, and it crosses the x-axis twice.
- If , the quadratic equation has one real root, and it touches the x-axis.
- If , the quadratic equation has two complex roots, and it neither crosses nor touches the x-axis.
---------------------
A quadratic equation has the following format:
It's roots are:
Thus
They are given by:
The discriminant is .
- If it is positive, , and thus, the quadratic equation has two real distinct roots, and it crosses the x-axis twice.
- If it is zero, , and thus, it has one real root, and touching the x-axis.
- If it is negative, is a complex number, and thus, the roots will be complex and will not touch the x-axis.
