Hello :
f(x) = 4x − 5 and g(x) = 3x + 9
(f + g)(x) = f(x) +g(x) = (4x-5) +(3x+9)
(f + g)(x) =7x +4
(f ⋅ g)(x) = f(x) × g(x) = (4x-5)(3x+9) = 12x² +36x -15x-45
(f ⋅ g)(x) = 12x² +21x -45
f[g(x)] = f(3x+9) = 4(3x+9) -5
f[g(x)] = 12x +31

A computer with software costs $2,938, and Catherine Stevens has agreed to pay a

Scorpion4ik [409]

Answer: She will pay 209.74056 each month

Step-by-step explanation:

firstly our cost of computer software = 2938

now the percentage rate of the finance charge per 18 months will be

finance charge rate per 18 months = (rate/12) * 18 = (19/12) * 18 = 28.5% = 0.285

now we find the finance charge

Finance charge = finance charge rate period * cash price

Finance charge = 0.285 * 2938 = 837.33

now we find the installment price

Installment price = finance charge + cash price

Installment price = 837.33 + 2938 = 3775.33

Installment payment = installment payments/number of payment (months)

Installment payment = 3775.44 / 18 = 209.74056

therefore she will pay a sum of 209.74056 each months.

Answer:

The suspect possesses 0.4 ounces of cocaine.

Step-by-step explanation:

Mass Units Conversion

The mass can be expressed in several units like grams, kilograms, ounces, pounds, etc. Each unit can be converted to any other multiplying by a fixed number.

The international conventions state that 1 gr = 0.035274 ounces.

If a suspect is in possession of 10 grams of cocaine, its equivalent to ounces can be calculated as 10*0.035274=0.35 oz. Rounding to the nearest tenth it would be 0.4 oz.

Since 1/8 = 0.125 and 1/2 is 0.5, our subject should be charged as a Class C felony
