Answer:

B

Step-by-step explanation:

Hello!

A function is a equation that every input has one output

To find if an equation is a function we put in a number for one variable and solve

I'll use 0

y^2 = 0^2 + 5(0) + 4

Simplify

y^2 = 0 + 0 + 4

Combine like terms

y^2 = 4

To remove the square from y you put 4 in the square root in both negative and positive

y=\sqrt{4} y=-\sqrt{4}

Simplify

y = 2, y = -2

For one input (0) we get two outputs (2 and -2) this means it is not a function. So the answer is B

Hope this Helps!

Maureen walked 3 miles how many feet did she walk
Ostrovityanka [42]

Answer:

15,840 feet.

Step-by-step explanation:

We have been given that Maureen walked 3 miles. We are asked to convert the distance walked by Maureen in feet.

Since we know that 1 mile equals 5,280 feet, so to convert our given distance we will multiply 3 by 5,280.

\text{Number of feet Maureen walked}=\text{3 miles}\times \frac{5,280\text{ feet}}{\text{Mile}}

\text{Number of feet Maureen walked}=3\times 5,280\text{ feet}

\text{Number of feet Maureen walked}=15,840\text{ feet}

Therefore, Maureen walked 15,840 feet.

Triangle EFG is dilated by a scale factor of 1/4 ​ to form triangle E'F'G'. Side E'F' measures 12.512.5. What is the measure of
WINSTONCH [101]

Answer: 3.125

Step-by-step explanation:

Given

Triangle is dilated by a factor of \frac{1}{4} i.e. each side multiplies to 0.25.

Side E'F' becomes 0.25 times the original length

\Rightarrow E'F'=\dfrac{1}{4}\times 12.5=3.125

Hund’s rule of maximum multiplicity specifies that _____. A. electrons will fill orbitals of lower energy first, pairing up only
djverab [1.8K]

Answer:

A. electrons will fill orbitals of lower energy first, paring up only after each orbital of the same energy already has one electron

Step-by-step explanation:

The rule states that for a given electron configuration, the lowest energy term is the one with the greatest value of spin multiplicity. This implies that if two or more orbitals of equal energy are available, electrons will occupy them singly before filling them in pairs.
