Sam Smith is purchasing a home. The selling price is $107,000. He is acquiring a new conventional loan and decides to make a 10%

kotykmax [81]

Answer:

$214

Step-by-step explanation:

selling price= $107,000

subtract 10%down payment

107,000- (107,000*.1)

107,000-107,00

96,300

Interest rate= 8%

Annual payment= 96,300* 0.08

$7704

per month payment= 7704/12

$624

payment on closing only for 10 days

642*(10/30)

$214

Find the volume V of the solid obtained by rotating the region bounded by the given curves about the specified line.? y = 2 + se

sertanlavr [38]

Answer:

The volume of the solid is: $\mathbf{V = \pi [ \dfrac{8 \pi}{3} - 2\sqrt{3}]}$

Step-by-step explanation:

GIven that :

$y = 2 + sec \ x , -\dfrac{\pi}{3} \leq x \leq \dfrac{\pi}{3} \\ \\ y = 4\\ \\ about \ y \ = 2$

This implies that the distance between the x-axis and the axis of the rotation = 2 units

The distance between the x-axis and the inner ring is r = (2+sec x) -2

Let R be the outer radius and r be the inner radius

By integration; the volume of the of the solid can be calculated as follows:

$V = \pi \int\limits^{\dfrac{\pi}{3}}_{\dfrac{-\pi}{3}} [(4-2)^2 - (2+ sec \ x -2)^2]dx \\ \\ \\ V = \pi \int\limits^{\dfrac{\pi}{3}}_{\dfrac{-\pi}{3}} [(2)^2 - (sec \ x )^2]dx \\ \\ \\ V = \pi \int\limits^{\dfrac{\pi}{3}}_{\dfrac{-\pi}{3}} [4 - sec^2 \ x ]dx$

$V = \pi [4x - tan \ x]^{\dfrac{\pi}{3}}_{\dfrac{-\pi}{3}} \\ \\ \\ V = \pi [4(\dfrac{\pi}{3}) - tan (\dfrac{\pi}{3}) - 4(-\dfrac{\pi}{3})+ tan (-\dfrac{\pi}{3})] \\ \\ \\ V = \pi [4(\dfrac{\pi}{3}) - tan (\dfrac{\pi}{3}) + 4(\dfrac{\pi}{3})- tan (\dfrac{\pi}{3})] \\ \\ \\ V = \pi [8(\dfrac{\pi}{3}) - 2 \ tan (\dfrac{\pi}{3}) ]$

$\mathbf{V = \pi [ \dfrac{8 \pi}{3} - 2\sqrt{3}]}$

If you flip three fair coins, what is the probability that you'll get a tail on the first flip, a head on the secand flip. And a

DENIUS [597]

Answer:

Probability of getting {THT} is 0.125

Step-by-step explanation:

Since 3 fair coins are tossed we can get the sample space for the experiment.

Sample space of the experiment = {HHH, HHT, HTT, HTH, TTH, THH, THT, TTT}

As per question ,

Getting Tail , Head, Tail is a success so all other events other than {THT} is a failure.

Therefore probability of getting {THT} = $\frac{1}{8}$ = 0.125

What number should be added to both sides of the equation to complete the square? X^2+12x

Zanzabum

The number that should be added to both sides is 16 because its half of b, which is then squared. You then get (x+4)^2=20, which you then square root both sides and get x+4=+-20 and then subtract the 4 to get x=-4+-20

I dont understand this.

iren2701 [21]

Answer:

88% left to consume

Step-by-step explanation:

880 of 1000

88/100

percentages are out of 100

so you can just divide both sides by 100, or take away the extra zero

let me know if you need further guidance ;)
