Answer:

Solutions given;

Using cosine rule

b²=a²+c²-2*a*c*cos B°

b²=15²+8²-2*15*8*cos39

b²=102.48

b= $\sqrt{102.48}$

b=10.12

b=10.1

Using sine rule

$\frac{sin A}{BC} = \frac{sin B}{AC} =\frac{sin C}{AB}$

$\frac{sin 29°}{15} =\frac{sin C}{8}$

Doing criss cross multiplication

Sin C= $\frac{sin 29°}{15} ×8$

m<C=Sin -¹(0.29)

m<C=14.98

m<C=15°is a required answer.

Answer:

$y=-e^{-3x-c_1}+6$

Step-by-step explanation:

$\frac{dy}{dx}+3y=18\\\\\mathrm{Substitute\quad }\frac{dy}{dx}\mathrm{\:with\:}y'\:\\\\y'\:+3y=18\\\\Rewrite\\\\\frac{1}{6-y}y'\:=3\\\\Solve \::\frac{1}{6-y}y'\:=3\\\\-In(6-y)=3x+c_1\\\\Isolate\:y\\\\\\y=-e^{-3x-c_1}+6$

A commercial property purchased for 1.2 million is revalued at 995,000. Calculate the percentage decrease in the property’s valu

soldi70 [24.7K]

Answer:

17%

Step-by-step explanation:

First: work out the difference (decrease) between the two numbers you are comparing. Then: divide the decrease by the original number and multiply the answer by 100.

First:

1,200,000 - 995,000 = 205,000

Then:

205,000 / 1,200,000 = 0.17

0.17 × 100% = 17%
