Charles owed $390 to his friend. On the first day Charles paid his friend $12. Each following week the amount Charles paid his f

tensa zangetsu [6.8K]

Hello! Ok, so this is the formula x10 + 12 = 390 =
x10 + 12 - 12 = 390 - 12 = 378 =
x10 = 378 =
x10 / 10 = 378 / 10 =
x = 37.80$
He paid 37.80$ per payment

Determine for which values of m the function variant Φ(x) = x^m is a solution to the given equation. a. 3x^2 (d^2y/dx^2) + 11x(d

miv72 [106K]

Answer:

a) m = -9 or m = 1

b) m = 1 + √6 or m = 1 -√6

Step-by-step explanation:

for

Φ(x) = x^m

then

dΦ/dx (x) = m*x^(m-1)

d²Φ/dx² (x) = m*(m-1)*x^(m-2)

then

for a

3x^2 (d^2y/dx^2) + 11x(dy/dx) - 3y = 0

3x^2*m*(m-1)*x^(m-2) + 11*x* m*x^(m-1) - 3*x^m = 0

3*m*(m-1)*x^m + 11*m*x^m- 3*x^m = 0

dividing by x^m

3*m*(m-1) + 11*m - 3 =0

3*m² + 8 m - 3 =0

m= [-8 ± √(64 + 4*3*3)]/2 = (-8±10)/2

m₁ = -9 , m₂= 1

then Φ(x) = x^m is a solution for the equation a , when m = -9 or m = 1

for b)

x^2 (d^2y/dx^2) - x(dy/dx) - 5y = 0

x^2*m*(m-1)*x^(m-2) - x* m*x^(m-1) - 5*x^m = 0

m*(m-1)*x^m -m *x^m- 5*x^m = 0

dividing by x^m

m*(m-1) -m - 5 =0

m² - 2 m - 5 =0

m= [2 ± √(4 + 4*1*5)]/2 = (2±√24)/2 = 1 ±√6

m₁ = 1 + √6 , m₂ = 1 - √6

then Φ(x) = x^m is a solution for the equation b , when m = 1 + √6 or m = 1 - √6

Molly is buying a house for $202,000. she is financing $185,500 and obtained a 30 year fixed rate mortgage with a 5.125% interes

IRINA_888 [86]

The value of the Financing loan is $185,500 . The Rate per month is 5.125%.

We will use the formula $PV = PMT \times\frac{( 1 - ( 1+r)^{-n})}{r}$

Where PV is the Present Value of financing, which is $185,500

PMT=Payment every month, which is to be found.

r=interest rate=5.125%

n=number of months in 30 years=12\times 30=360

$\therefore 185,500 = PMT \times \frac{1-(1+\frac{5.125}{1200})}{\frac{5.125}{1200}} =PMT \times 183.6591$

Therefore, $PMT =\frac{185,500}{183.6591}=1010.02$

Therefore Molly's monthly payments are $1010.02.

Thus Option A is the correct option.
