kompoz [17]4 years ago
8 0

Answer:

\frac{-27}{x^{15}}=-\frac{27}{x^{15}}

Step-by-step explanation:

<em>If you just want to simplify -27/x^15, it is not very difficult. Here is the simple way.</em>

<em />

Given the expression

\frac{-27}{x^{15}}

solving

\frac{-27}{x^{15}}

\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}

=-\frac{27}{x^{15}}

Therefore,

\frac{-27}{x^{15}}=-\frac{27}{x^{15}}

What is the value of y?
Kobotan [32]

Answer:

B. 65°

Step-by-step explanation:

Angles on a straight line add up to 180 degrees.

180 - 130 = 50

Angles in a triangle add up to 180 degrees.

y + y + 50 = 180

2y + 50 = 180

2y = 180 -50

2y = 130

y = 130/2

y = 65

Someone please help me!
kvasek [131]

The formula for compounded interest in this type of equation is:

A = P(1+\frac{r}{n})^{nt} where A is the amount at the end of the time period, P is the principal amount you start with, R is the interest rate, N is the amount of compound periods, and T is the time allotted for the money to gain interest.

P = 5000, R = 3% or 0.03, N = monthly so 12, T = 2 years

Plug in our given information into the equation:

A = 5000(1 +\frac{.03}{12})^{12(2)} \\ A = 5000(1 + \frac{.03}{12})^{24}

Let the calculator do the work here...

A ≈ 5308.785 which rounds to A ≈ 5308.79

Option A is your answer.

Write an exponential function whose graph passes through the given points (0, - 2) and (- 1, - 4)
melamori03 [73]

Answer:

y = 2(0.5) {}^{x}

Step-by-step explanation:

Use the general formula of exponential equation

y = ab {}^{x}

Plug 0,2 into the function

- 2 = ab {}^{0}

- 2 = a \times 1

a =  - 2

y =  - 2b {}^{x}

- 4 =  - 2b {}^{ - 1}

2 = b {}^{  - 1}

{2}^{ \frac{ 1}{ - 1} }

2 {}^{ - 1}  = 0.5

B=0.5

y = 2(0.5) {}^{x}

The spread of a flu virus on a college campus is modeled by y= 5000/(1+4999e^-0.8t), where y is the number of students infected
Darina [25.2K]

Answer:

537 students

11 days

Step-by-step explanation:

       5000

y=  -----------------

    (1+4999e^-0.8t)

a)  after 8 days  means t =8


       5000

y=  -----------------

    (1+4999e^-0.8*8)

       5000

y=  -----------------

    (1+4999e^-6.4)

       5000

y=  -----------------

    (1+8.306)

       5000

y=  -----------------

    (9.306)

y =537.28

Rounding to the nearest student

y = 537 students


b)  1/2 the student population  means y =2500  (The 5000 is the student population)

             5000

2500=  -----------------

        (1+4999e^-0.8t)

Multiply each side by  (1+4999e^-0.8t)

2500 (1+4999e^-0.8t) = 5000

Divide each side by 2500

(1+4999e^-0.8t) = 5000/2500

(1+4999e^-0.8t) = 2

Subtract 1

(4999e^-0.8t) = 2-1

(4999e^-0.8t)=1

Divide by 4999

(4999/4999e^-0.8t)=1/4999

e^-0.8t=1/4999

Take the natural log of each side

ln(e^-0.8t)=ln(1/4999)

-.8t = ln(1/4999)

Divide by -.8

-.8/-8t = -1/.8 *ln(1/4999)

t = -1/.8 *ln(1/4999)

t≈10.6462

Rounding, it will take 11 days
