Answer:

B.There can only be one voltage supplied.

Step-by-step explanation:

Moving electrons constitute current. When the electrons move in single direction, it is known as Direct current (DC). When the electrons move back and forth, it is known as Alternating current (AC).

Voltage transferred from the power plants to out home is in the form of AC. A high voltage AC can be converted to low voltage AC and vice-versa using transformer.

DC is used for very small power requirement as such in cells of clocks, remotes etc. One single voltage can be supplied using DC. It cannot be increased or decreased.

Emily needs enough Fabric for 3 1/2 hats. Since she has half a hat done. If each bag requires 1 2/7 ft of Fabric, how much fabri
kow [346]

first off let's convert the mixed fractions to improper fractions.

\stackrel{mixed}{3\frac{1}{2}}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}} ~\hfill \stackrel{mixed}{1\frac{2}{7}}\implies \cfrac{1\cdot 7+2}{7}\implies \stackrel{improper}{\cfrac{9}{7}}

she already did half a hat, so we can say   \cfrac{7}{2}-\cfrac{1}{2}\implies \cfrac{7-1}{2}\implies 3

so she only needs enough fabric to make 3 more full hats, we know each one uses 9/7 ft, so

3\cdot \cfrac{9}{7}\implies \cfrac{27}{7}\implies 3\frac{6}{7}

Determine if the function is one-to-one.<br><br>​
olya-2409 [2.1K]

Answer:

No

Step-by-step explanation:

From what I saw on google for what "one to one" means, It's basically meaning that the bottom of that quadratic function is at point (0 , 0) and hits both (-1 , 1) and (1 , 1) on the graph.
