Kate needs to read 2 books over summer vacation. She doesn't have the books yet so she's not sure how many pages are in each boo

Kobotan [32]

Answer:

(x+y) / 72

Step-by-step explanation:

Kate needs to read 2 books

she's not sure how many pages are in each book.

Let

Number of pages in the first book = x

Number of pages in the second book = y

Total pages of the two books = x + y

Kate's summer vacation = 72 days

she is planning to read the same number of pages each day of her summer vacation.

Number of pages she will need to read each day = (x+y) pages / 72 days

Number of pages she will need to read each day = (x+y) / 72

In this diagram, BAC~ EDF. if the area of BAC = 6 in, what is the area of EDF.

gulaghasi [49]

Answer:

2.7 square inch

Step-by-step explanation:

$\triangle BAC \sim \triangle EDF... (Given) \\$

$\therefore$ By area of similar triangle theorem:

$\frac{A(\triangle BAC)}{A(\triangle EDF)} = \frac{BC^2}{EF^2} \\\\\therefore \frac{6}{A(\triangle EDF)} = \frac{3^2}{2^2} \\\\\therefore \frac{6}{A(\triangle EDF)} = \frac{9}{4} \\\\\therefore A(\triangle EDF) = \frac{4\times 6}{9} \\\\\therefore A(\triangle EDF) = \frac{24}{9} \\\\\therefore A(\triangle EDF) = 2.6667\\\\\huge \purple {\boxed {\therefore A(\triangle EDF) = 2.7\: in^2}}$

Not sure how I am supposed to arrive to an answer

ANEK [815]

Integrating both sides once gives

$\dfrac{\mathrm d\mathbf r}{\mathrm dt}=2e^t\,\mathbf i+3e^{-t}\,\mathbf j+4e^{2t}\,\mathbf k+\mathbf c$

where $\mathbf c$ is an arbitrary constant vector. Use the initial condition to find its value:

$\dfrac{\mathrm d\mathbf r}{\mathrm dt}(0)=-\mathbf i+7\,\mathbf j=(2+c_1)\,\mathbf i+(3+c_2)\,\mathbf j+(4+c_3)\,\mathbf k$

$\implies\mathbf c_1=-3\,\mathbf i+4\,\mathbf j-4\,\mathbf k$

Integrate again:

$\mathbf r(t)=2e^t\,\mathbf i-3e^{-t}\,\mathbf j+2e^{2t}\,\mathbf k+\mathbf c_1t+\mathbf c_2$

where $\mathbf c_2$ is another arbitrary vector of constants. Use the other initial condition to determine its components:

$\mathbf r(0)=6\,\mathbf i+\mathbf j+3\,\mathbf k=(2+c_1)\,\mathbf i+(-3+c_2)\,\mathbf j+(2+c_3)\,\mathbf k$

$\implies\mathbf c_2=4\,\mathbf i+4\,\mathbf j+\mathbf k$

Then the particular solution to this ODE is

$\boxed{\mathbf r(t)=(2e^t-3t+4)\,\mathbf i+(-3e^{-t}+4t+4)\,\mathbf j+(2e^{2t}-4t+1)\,\mathbf k}$
