The price of a home is $300,000. After a 10% down payment, the mortgage is $270,000. If this is financed with a 30-year fixed-ra

irinina [24]

Answer:

The correct solution is "$1618.79".

Step-by-step explanation:

The given values are:

Home price,

= $300,000

Down payment,

= 10%

Mortgage,

= $270,000

Rate,

r = 6%

Time,

t = 30 years

As we know,

⇒ $PV=P[\frac{1-(1+r)^{-n}}{r} ]$

On substituting the values, we get

⇒ $270 000= P[\frac{1-(1+\frac{6}{1200} )^{-12\times 30}}{\frac{6}{1200} } ]$

⇒ $P=1618.79$ ($)

choli [55]

The average cost of a two-bedroom apartment in the city will be about $1135

Step-by-step explanation:

The regression line equation is yˆ=1.377x+137.763 where x is the cost of one-bedroom apartment.

Given that the average cost of one-bedroom apartment is $724, then using this value for x

yˆ=1.377*724+137.763 = 1134.711

This value is approximately $ 1135

A football player kicks a ball with an initial upward velocity of 47 ft./s. The initial height of the ball is 3 feet. The functi

Rashid [163]

Answer: 3 seconds

We are given the following function:

$h(t)=-16{t}^{2}+V.t+h(o)$ (1)

Where:

$t$ is the time the ball is in the air

$V=47ft/s$ the initial upward velocity

$h(o)=3ft$ the initial height of the ball

$h(t)$ is the final height of the ball. If no one catches it, this will be <u>zero</u>

So, equation (1) changes to:

$-16{t}^{2}+V.t+h(o)=0$ (2)

Substituting the known values:

$-16{t}^{2}+(47ft/s).t+3ft=0$ (3)

This is a quadratic equation in the form $a{t}^{2}+b.t+c=0$ . In order to find $t$ we can use the quadratic formula for the roots:

$t=\frac{-b\pm\sqrt{-4ac}}{2a}$ (4)

Where $a=-16$ , $b=47$ and $c=3$

Substituting this values in (4):

$t=\frac{-47\pm\sqrt{-4(-16)(3)}}{2(-16)}$ (5)

$t=\frac{-47\pm\sqrt{2401}}{-32}$ (6)

$t=\frac{-47\pm\49}{-32}$ (7)

For $t1$ :

$t1=\frac{-47+49}{-32}=-0.0625 s$ (8)>>>> This result does not work for us because is negative

For $t2$ :

$t2=\frac{-47-49}{-32}=3 s$ (9)>>>This is the result

Therefore:

<h2> If no one catches the ball, it will be 3 s in the air</h2>
