Answer:

13/15

Step-by-step explanation:

Solve using implicit differentiation:

First take derivative:

6y $\frac{dy}{dx}$ -3 $\frac{dy}{dx}$ -10x+7 = 0

Next isolate the $\frac{dy}{dx}$ :

6y $\frac{dy}{dx}$ -3 $\frac{dy}{dx}$ = 10x-7

$\frac{dy}{dx}$ (6y-3) = 10x-7

$\frac{dy}{dx}$ = $\frac{10x-7}{6y-3}$

Finally plug in the point (2,3):

$\frac{10(2)-7}{6(3)-3} = \frac{13}{15}$

Answer:

$A = 43.0^o$

$B = 55.0^o$

$BC = 20.0$

Step-by-step explanation:

I will solve this question with the attached triangle

From the attachment, we have:

$\angle C =82^o$

$AB = 29$

$AC = 24$

Required

Solve the triangle

First, we calculate $\angle B$ using sine law:

$\frac{AC}{\sin(B)} = \frac{AB}{\sin(C)}$

This gives:

$\frac{24}{\sin(B)} = \frac{29}{\sin(82^o)}$

$\frac{24}{\sin(B)} = \frac{29}{0.9903}$

Cross multiply

$\sin(B) * 29 = 24 * 0.9903$

$\sin(B) * 29 = 23.7672$

Divide both sides by 29

$\sin(B) = 0.8196$

Take arcsin of both sides

$B = \sin^{-1}(0.8196)$

$B = 55.0^o$

Next, calculate $\angle A$ using:

$A + B + C = 180^o$ --- angles in a triangle

$A + 55^o + 82^o = 180^o$

Collect like terms

$A = 180^o-55.0^o - 82^o$

$A = 43.0^o$

Next, calculate BC using sine laws

$\frac{BC}{\sin(A)} = \frac{AB}{\sin(C)}$

This gives:

$\frac{BC}{\sin(43.0)} = \frac{29}{\sin(82)}$

$\frac{BC}{0.6820} = \frac{29}{0.9903}$

Make BC the subject

$BC = \frac{29*0.6820}{0.9903}$

$BC = 20.0$

Hello :D

£8000 - £2000 = £6000

6 x 500 = £3000

Answer:

$147,848.5

Step-by-step explanation:

Fixed rate =7.35%

Mortgage Loan= $685,000

Selling price=$782,000

Property tax paid= $14,578.15

Therefore,

Prorated Amount Owed= Outstanding balance on the house + Interest paid on the loan for the year

Prorated Amount Owed=(782500-685000)+7.35% of 685000

=97500+50347.5

=$147,847.5
