Answer:
D
Step-by-step explanation:
it's the only one where the y of each point has a linear (even if constant) trend, the others go up and down
Answer:
y = (x - 10)^2 / 100 + 1
Step-by-step explanation:
given:
A suspension footbridge has two 2-meter vertical supports 20 meters apart so the cable connecting 'em will be a convex parabola
The lowest point of the cable, which is the vertex, 1 meter above the path.
y-axis represents the left support and the other vertical support is at x=20
by symmetry, the vertex is mid-pt between the two supports, @ x=20/2=10
so vertex is at (10,1)
vertex form of parabola is y = a(x - h)^2 + k, where (h, k) is the vertex
so y = a(x-10)^2 + 1
at y-axis, x=0, y=2
2 = a(0-10)^2 + 1
2 - 1 = 100a
a = 1/100
so the eqn is y = (x - 10)^2 / 100 + 1

Answer:
y^12x^2
Step-by-step explanation:
Katelyn's balloon payment will be $127, 619.33.
We have PV (present value) of $368, 375 to be paid in 240 months (20 years, indicated by 20/6) with a mortgage at 4.65% (Annual Interest rate) to be converted into monthly interest rate (4.65/12= 0.3875%).
Using the formula:
P(Balloon) = (PV)(1+r)^n - P[((1+r)^n-1)/r)]
Balloon payment is the amount that has a term that is shorter than its amortization.
