Step-by-step explanation:

F and g are functions such that

F(x)=3/x2 and g(x)=2x3

A) find f(-4)
B) find fg(1)

Answers

f(-4) = 3/(-4)(2)
f(-4)= 3/-8

f(g(1))= 3/(2(1)^3)(2)
f(g(1))= 3/(2)(2)
f(g(1))= 3/4

a. The value of f(-4) is [tex]3 \div -8[/tex]

b. The value of fg(1) is [tex]3\div 4[/tex]

Calculation of the value of f(-4) and fg(1):

Since [tex]F(x)=3\div x\times 2\ and\ g(x)=2\times x\times 3[/tex]

So,

a. The value of f(-4) is

[tex]= 3\div (-4)(2)\\\\= 3\div -8[/tex]

And,

b. The value of fg(1) is

[tex]= 3\div (2(1)^3)(2)\\\\= 3\div (2)(2)\\\\= 3\div 4[/tex]

What is a simplification in math?

In mathematics, genuinely or simplification is reducing the expression/fraction/hassle in a less complicated form. It makes the problem smooth with calculations and fixing.

Does simplifying suggest fixing?

Associated with "simplification" troubles are some "solving" troubles. just as a few expressions include parentheticals or even nested grouping symbols, so additionally do some equations. The simplification manner is identical, whether we're running with expressions (and consequently handiest simplifying) or equations (so we are also solving).

. A bakery sells 1,230 cakes during a holiday season. One-third of them are caramel cakes, one-half are chocolate cakes, and the remaining are banana cakes. What is the total amount earned by the bakery by selling the cakes during the holiday season?

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]Cakes = 1230[/tex]

[tex]Caramel = \frac{1}{3}[/tex]

[tex]Chocolate = \frac{1}{2}[/tex]

[tex]Banana = ??[/tex]

Required

Determine the total amount earned

The given parameters can't be used to determine the total amount earned.

However, we'll make some assumptions

First, we need to solve for the amount of each cake sold

[tex]Caramel = \frac{1}{3}[/tex]

[tex]Caramel = \frac{1}{3} * 1230[/tex]

[tex]Caramel = 410[/tex]

[tex]Chocolate = \frac{1}{2}[/tex]

[tex]Chocolate = \frac{1}{2} * 1230[/tex]

[tex]Chocolate = 615[/tex]

[tex]Banana = 1230 - 410 - 615[/tex]

[tex]Banana = 205[/tex]

Assume that:

Each caramel were sold at x

Each chocolate were sold at y

Each banana were sold at z

[tex]Total\ Amount = 410 * x + 615 * y + 205 * z[/tex]

[tex]Total\ Amount = 410x + 615y + 205z[/tex]

1. Which is the smallest set of real numbers that contains the value below? -18 /6
A. Irrational Numbers
B. Rational Numbers
C. Natural Numbers
D. Integers​

Answers

Answer:

Integers

Step-by-step explanation:

The correct option to choose is the integers option. Integers are simply whole numbers.

Thus-18/6 = -3

The term -3 is a whole number

So the term to choose is the integers option

The smallest set of real numbers that contains the value -18 /6 is an integer.

The smallest set of the real number that contains the value -18/6 can be determined after we have simplified the expression -18/6.

To simply the given expression, we will divide both the numerator and the denominator by 6, by doing so, we have:

= -3

Now, the smallest set of the real number is = -3 which is an integer

This is because an integer is a whole number that is not a fraction and can be negative or positive.

The reason why it is not a natural number is because of the negative sign, since we know that natural numbers are numbers with positive signs only.
