Answer: Put 2 of these on your paper! :D
Astronomers use the entire electromagnetic spectrum to observe a variety of things. Radio waves and microwaves – the longest wavelengths and lowest energies of light – are used to peer inside dense interstellar clouds and track the motion of cold, dark gas.
Answer:
c. Use a compass to swing an arc on either side of the segment for each endpoint.
Step-by-step explanation:
The steps to constructing a perpendicular bisector are illustrated in the attachment.
Steps 2 and 3 are described by answer choice C.

<em>Other choices</em>
(a) In order to get the arcs to intersect each other, their radius must be <em>more than</em> one half of the segment length.
(b) At no point in the construction are concentric circles involved.
(c) A ruler is not used in any <em>construction</em>. Only a straightedge with no markings will be used for construction.
Answer:
f(x) = x + 2
Step-by-step explanation:
A linear function has the form
f(x) = mx + c
Evaluate f(0) = 2, that is
2 = m(0) + c
2 = 0 + c ⇒ c = 2
Evaluate f(2) = 4, that is
4 = 2m + c ← substitute c = 2
4 = 2m + 2 ( subtract 2 from both sides )
2 = 2m ( divide both sides by 2 )
1 = m
Hence
f(x) = x + 2 ← is a possible linear function
Multiply these together... $55.20 + $27.60 + $2.21 = $85.01 or $85
