Answer: The length of CU is 117 units.


Step-by-step explanation:

Given: ΔWCD≈ΔWUV

We know that if two triangles are similar, then their corresponding sides are proportional.

∴ \frac{WU}{WC}=\frac{WV}{WD}

\frac{36x-1}{26}=\frac{110}{20}\\\Rightarrow\ 36x-1=\frac{11}{2}\times26\\\Rightarrow36x-1=143\\\Rightarrow\ 36x=143+1\\\Rightarrow\ 36x=144\\\Rightarrow\ x=4

∴ WU=36(4)-1=143

Also , WU=WC+CU

⇒CU=WU-WC

⇒CU=143-26=117 units

Estimate the solution of the system of equations. Write the answer as an ordered pair.
sergeinik [125]

Answer:

Solution of the given system of equations is (1, 2.5)

Step-by-step explanation:

From the graph attached,

Two intersecting lines represent the system of equations.

And the solution of the system of equations is a common point where these lines intersect.

Graph shows both the line are intersecting each other at (1, 2.5).

Therefore, solution of the given system of equations will be (1, 2.5).

The table shows the number of books donated to a library each month. Suppose the growth continues exponentially.
telo118 [61]
\bf \begin{array}{ccll}&#10;\stackrel{t}{months}&\stackrel{A}{books}\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;0&80\\&#10;1&100\\&#10;2&125&#10;\end{array},    we know that on Month 0, the Books were 80

\bf \qquad \textit{Amount for Exponential Growth}\\\\&#10;A=I(1 + r)^t\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\to &80\\&#10;I=\textit{initial amount}\\&#10;r=rate\to r\%\to \frac{r}{100}\\&#10;t=\textit{elapsed time}\to &0\\&#10;\end{cases}&#10;\\\\\\&#10;80=I(1+r)^0\implies 80=I\qquad therefore\qquad \boxed{A=80(1+r)^t}

we also know that on the first month there were 100 books,

\bf \qquad \textit{Amount for Exponential Growth}\\\\&#10;A=I(1 + r)^t\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\to &100\\&#10;I=\textit{initial amount}\\&#10;r=rate\to r\%\to \frac{r}{100}\\&#10;t=\textit{elapsed time}\to &1\\&#10;\end{cases}&#10;\\\\\\&#10;100=80(1+r)^1\implies \cfrac{100}{80}=1+r\implies \cfrac{5}{4}=1+r&#10;\implies &#10;\cfrac{5}{4}-1=r&#10;\\\\\\&#10; \cfrac{1}{4}=r\implies 0.25=r\qquad therefore\qquad \boxed{A=80(1+0.25)^t}

now, how many books when t = 8?   A=80(1+0.25)⁸, or A=80(1.25)⁸.
