Ms walkers science class is doing an egg drop experiment from the balcony of their school. Each egg is protected by a contraptio

mr_godi [17]

Answer:

The zeros, -1.48 and 1.48, represent the times where the egg is on the ground.

Step-by-step explanation:

The roots, or zeros, of an expression are the x-intercepts. They are the points where the data crosses the x-axis. The y-coordinate at these points is 0. This means the height of the egg at these points is 0.

The values of a, b and c in this equation are -16, 0 and 35. Using the quadratic formula,

$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}\\\\=\frac{-0\pm \sqrt{0^2-4(-16)(35)}}{2(-16)}\\\\=\frac{0\pm \sqrt{0--2240}}{-32}\\\\=\frac{0\pm \sqrt{2240}}{-32}\\\\=\frac{0\pm 47.33}{-32}\\\\=\frac{0+47.33}{-32}\text{ or }\frac{0-47.33}{-32}\\\\=\frac{47.33}{-32}\text{ or }\frac{-47.33}{32}\\\\=-1.48\text{ or }1.48$

Frank has four different credit cards, the balances and interest information of which are outlined in the table below. He would

Brums [2.3K]

Answer:

c. $467.29

Step-by-step explanation:

The total of balances is $9360. The payment can be computed using the amortization formula:

A = P(r/12)/(1 -(1 +r/12)^-n)

where A is the monthly payment, P is the principal (total balance), r is the annual rate, and n is the number of months.

Filling in your numbers, we have ...

A = $9360(0.18/12)/(1 -(1 +0.18/12)^-24) ≈ $467.29

Frank's monthly credit card payment will be $467.29.
