What is a mathematical function, equation and expression?

• function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.

• expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.

• equation : A mathematical equation is used to equate two expressions.

Given is that you are working in a hospital supply room and make $13.65 an hour. The union negotiates a new contract giving each employee a 4.3% cost of living raise

Assume that the new hourly rate be $[x]. Then, we can write -

[x] = 13.65 + {4% pf 13.65}

[x] = 13.65 + {4/100 x 13.65}

[x] = 13.65 + 0.546

[x] = 14.196

Therefore, the new hourly rate will be $14.196 per hour.

Step-by-step explanation:

Total number of stickers is 500.

25% of the total number is hearts:

• 500*25/100 = 125 heart stickers

The rest of the stickers are stars:

• 500 - 125 = 375 star stickers

Answer:

i. 31/25

ii. 1/5

Step-by-step explanation:

you know that tanx = 3/4, so you can also find that sinx = 3/5 and cosx = 4/5. Then you can use the double angle identities to find cos2x and sin2x: cos^2(x) - sin^2(x) + 2sinxcosx and substitute the givens to get 31/25. Then, cosx - sinx is obviously 1/5.
