Answer:

Quadratic Equation:

3x^2=2x +5

\text{Standard Form: } 3x^2-2x-5=0

From the standard form of a Quadratic Function, we get:

a=3,\:b=-2,\:c=-5

Discriminant:

\Delta=\left(-2\right)^2-4\cdot \:3\left(-5\right)

\Delta=\left(-2\right)^2+4\cdot \:3\cdot \:5

\Delta=64

From the discriminant, we conclude that the equation will have two real solutions.

State that:

b^2-4ac

b^2-4ac =0:\text{The equation has 1 real solution}

b^2-4ac >0:\text{The equation has 2 real solutions}

By the way, solving the equation given:

$x=\frac{2\pm\sqrt{64}}{2\cdot \:3}$

$x=\frac{2\pm\sqrt{64}}{6}$

$x=\frac{2\pm8}{6}$

$x_{1} =\frac{10}{6}=\frac{5}{3}  $

$x_{2}=\frac{-6}{6} =-1$

Riverside bank offers to lend you $50,000 at a nominal rate of 6.5%, compounded monthly. the loan (principal plus interest) must
Neporo4naja [7]

The effective annual rate of Midwest is 0.2% lower than the rate charged by Riverside.

Further Explanation:

Riverside Bank:

Principal = $50,000

Duration = 1 year

APR = 6.5%

The amount paid after 1 year is

A = 50000(1 + 0.065/12)¹² = $53,348.59

Midwest Bank:

Principal = $50,000

APR = 6.2%

Duration = 1 year

The amount paid after 1 year is

A = 50000*(1 + 0.062) = $53,100.00

The amount charged by Midwest is lower:

Let r = the effective annual rate of Riverside Bank.

Then

50000*(1 + r) = 53348.59

1 + r = 53348.59/50000 = 1.067

r = 0.067 = 6.7%

Effective annual rate:  

The viable yearly financing cost is the loan fee that is really earned or paid on a venture, advance or other money related item because of the aftereffect of intensifying over a given timeframe. It is additionally called the powerful loan cost, the viable rate or the yearly comparable rate.  

Instructions to Calculate the Effective annual Rate:  

1. Determine the expressed loan fee. The expressed financing cost (additionally called yearly rate or ostensible rate) is generally found in the features of the credit or store understanding.

2. Determine the quantity of aggravating periods.  

3. Apply the EAR Formula: EAR = (1+ I/n)n – 1.

the part of a dish designed for ice cream is shaped like an upside-down cone. The base of the cone has a radius of 2 inches and
Lena [83]

Answer: 5.02\ in^3

Step-by-step explanation:

For this exercise you need to use the following formula to solve this exercise, which is used to calculate the voume of a cone:

V=\frac{1}{3}\pi  r^2 h

Where "r" is the radius and "h" is the height of the cone.

In this case, based on the information given the exercise, you can identify that:

r=2\ in\\\\h=1.2\ in

Knowing those values, you can substitute them into the formula:

V=\frac{1}{3}\pi  (2\ in)^2 (1.2\ in)

Finally, evaluating, you get the following result:

V=5.02\ in^3

Therefore, 5.02\ in^3 will fit in the cone.
