Goodmorning I need help with this question. And may you explain to me how to get this right step by step. Thank you.​
katen-ka-za [31]

Answer:

I think it's "C"

Step-by-step explanation:

Because a function is the independent variable to the dependent variable... Since, the cost relies on the weight, the cost is dependent. While, the weight is independent. I don't know if I'm right, I kinda suck at math

Given ΔADC and ΔAEB, What is AE?
chubhunter [2.5K]

Answer:

AE = 43.2 units

Step-by-step explanation:

As per the given question image, it can be seen that in the \triangle ADC \text { and }\triangle AEB :

1. \angle B = \angle C = 90^\circ

2. \angle A is common to both the triangles.

3. Two angles are common, so the third angle \angle E is also equal to \angle D.

All the three angles in the \triangle ADC \text { and }\triangle AEB are equal to each other, hence the triangles are similar.

As per the property of similar triangles, the ratio of their sides will be equal.

AB : AC = AE : AD

AC = 88 units

BC = 55 units

AB = AC - AB = 33 units

Let side AE = x units

Side AD = AE + ED

So, AD = x + 72

Using the ratio:

\dfrac{AB}{AC} = \dfrac{AE}{AD}\\\Rightarrow \dfrac{33}{55} = \dfrac{x}{x+72}\\\Rightarrow 55x = 33 \times 72\\\Rightarrow x = \dfrac{3\times 72}{5}\\\Rightarrow x = 43.2\ units

So, AE = 43.2 units

The population of a city is about 200,000 and is growing at a rate of 0.6% per year.
IgorC [24]
A)

\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=P(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{initial amount}\to &200000\\
r=rate\to 0.6\%\to \frac{0.6}{100}\to &0.006\\
t=\textit{elapsed time}\to &t\\
\end{cases}
\\\\\\
A=200000(1+0.006)^t\implies A=200000(1.006)^t

B)    \bf A=200000(1.006)^4
