PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
kondaur [170]

Answer: A. profit of $4500

<u>Step-by-step explanation:</u>

    r(x) = x² + 6x + 10

  - <u>c(x) = x² - 4x + 5</u>

(r - c)(x) =     10x + 5


(r - c)(4) = 10(4) + 5

           =  40 + 5

           = 45

(r - c)(x) represents the profit (in hundreds of dollars) in x months

(r - c)(4) represents the profit (in hundreds of dollars) in 4 months

So, the new store will have a profit of $4500 in 4 months

Which sentence is NOT a geometric progression?
DIA [1.3K]

<u>c) 3, 6, 9 12</u>  is NOT a geometric progression

<h3>Further explanation </h3>

Geometry sequences are series of numbers that have a constant ratio

or can be interpreted:

Each number is obtained by multiplying the previous number by a constant

The sequence can be:

a, ar, ar², ar³, ... etc.

Can be formulated

\large {\boxed {\bold x_n = ar ^ {n-1}}}

where:

a is the first term, and

r is the common ratio

So we have to see the series has the same ratio or not

a. \dfrac{5}{1}=\dfrac{25}{5}=5\to \rm geometric\:progression

b. \dfrac{8}{4}=\dfrac{16}{8}=2\to \rm geometric\:progression

c.\dfrac{6}{3}\neq \dfrac{9}{6}\to \rm not\:geometric\:progression

d. \dfrac{6}{2}=\dfrac{18}{6}=3\to \rm geometric\:progression

If the acceleration of an object is given by dv/dt = −2v, Find the position function s(t) if v(0) = 7 and s(0) = 0.
kirill [66]

Answer:

Step-by-step explanation:

Given that acceleration of an object is

\frac{dv}{dt} =-2v\\\frac{dv}{v} =-2dt\\ln v = -2t+C\\

is the solution to the differential equation

Since v(0) =7

we get ln 7 = C

Hence lnv = -2t+ln 7\\v=7e^{-2t}

since velocity is rate of change of distance s we have

v=\frac{ds}{dt} =7e^{-2t}\\s= [tex]s(t) =\frac{-7}{2} (e^{-2t})+C)[

substitute t=0 and s=0

C=7/2

So solution for distance is

s(t) =\frac{-7}{2} (e^{-2t}-1)

(4m+7n-6p)-(2m-3n-4p)
Vanyuwa [196]

Answer:

2m + 10n - 2p

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Distributive Property

<u>Algebra I</u>

  • Terms

Step-by-step explanation:

<u>Step 1: Define</u>

(4m + 7n - 6p) - (2m - 3n - 4p)

<u>Step 2: Simplify</u>

  1. Distribute negative:                    4m + 7n - 6p - 2m + 3n + 4p
  2. Combine like terms (m):             2m + 7n - 6p + 3n + 4p
  3. Combine like terms (n):              2m + 10n - 6p + 4p
  4. Combine like terms (p):              2m + 10n - 2p
