\bf \textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=11 \end{cases}\implies C=2\pi (11)\implies C=22\pi \\\\\\ \stackrel{~\hfill \textit{a semicircle has half of that}}{C=\cfrac{22\pi }{2}\implies C=11\pi \implies C\approx 34.56}

The constraint for the potential plant site 2 can be written as:
sdas [7]

Answer:

c. x21 + x22 + x23 less or equal than 2800 y2

Step-by-step explanation:

The plant has a maximum capacity of 2800 then the sum of all these operations must be equal to or less than 2800. The site of the plant has capacity constraint which needs to be determine through equation. The total capacity for the plant 2 is only 2800 the operation has to be distributed with keeping in mind the capacity limit.

Solve the following exponential equation:<br><br>5^x=2 <br><br>e^x=10​
olya-2409 [2.1K]

Number 1.

5^x=2, first we will take the log of both of these numbers getting us,

x=\frac{log(2)}{log(5)}, which then gives us that x=0.4306777777....

Number 2

e^x=10, solve for our exponent, 2.718282^x=10, use the logarithmic formula, and we get,

x=\frac{log(10)}{log(2.718282)}, which then we get that x=2.302585

I need to know how to get the scale factor from a h-shaped polygon
Lesechka [4]
“To find the scale factor, we simply create a ratio of the lengths of two corresponding sides of two polygons. If the ratio is the same for all corresponding sides, then this is called the scale factor and the polygons are similar.”
