Describe in your own words what a function is and include an example of a function?
Answers
A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
This means that if the object x
x
is in the set of inputs (called the domain) then a function f
f
will map the object x
x
to exactly one object f(x)
f
(
x
)
in the set of possible outputs (called the codomain).
The notion of a function is easily understood using the metaphor of a function machine that takes in an object for its input and, based on that input, spits out another object as its output.
Example: x2 (squaring) is a function
x3+1 is also a function
Sine, Cosine and Tangent are functions used in trigonometry
and there are lots more!

Answer:
(a) 259.5 days
(b) 284 days
Step-by-step explanation:
Let X represent the pregnancy length in days.
It is provided that [tex]X\sim N(270,9^{2})[/tex].
(a)
Let a represent the minimum pregnancy length that can be in the top 12% of pregnancy lengths.
Then,
P (X < a) = 0.12
⇒ P (Z < z) = 0.12
The corresponding z-score is, z = -1.17.
*Use a z-table.
Compute the value of x as follows:
[tex]z=\frac{x-\mu}{\sigma}\\\\-1.17=\frac{a-270}{9}\\\\z=270-(9\times 1.17)\\\\z=259.47\\\\z\approx 259.5[/tex]
Thus, the minimum pregnancy length that can be in the top 12% of pregnancy lengths is 259.5 days.
(b)
Let b be the maximum pregnancy length that can be in the bottom 6% of pregnancy lengths.
Then,
P (X > b) = 0.06
⇒ P (X < b) = 0.94
⇒ P (Z < z) = 0.94
The corresponding z-score is, z = 1.56.
*Use a z-table.
Compute the value of x as follows:
[tex]z=\frac{x-\mu}{\sigma}\\\\1.56=\frac{b-270}{9}\\\\z=270+(9\times 1.56)\\\\z=284.04\\\\z\approx 284[/tex]
Thus, the maximum pregnancy length that can be in the bottom 6% of pregnancy lengths is 284 days.

Find the distance between the parallel lines m and n whose equations are
(y = x + 4) and (y = x - 6.)
Answers
Answer:Find the distance between the parallel lines m and n whose equations are y = x + 4 and y = x - 6, respectively.
There are several ways to do this...here's one
Let (0, 4) be a point on the first line
Then.......a line with a negative reciprocal slope going through this point will have the equation :
y = -x + 4........so......we can find the intersection of this line with y = x - 6....set both equations equal
-x + 4 = x - 6 add x, 6 to both sides
10 = 2x divide both sides by 2
5 = x
So...using -x + 4, the y value at intersection = -1.......
So...we just need to find the distance from (0,4) to ( 5, -1) =
√[ (5)^2 + (4 + 1)^2 ] = 5√2 ≈ 7.07 units
Here's a pic....AB is the distance with A = (0,4) and B = (5, -1)

20 = 8x + 4y
what is y?
Answers
Answer:
y = -2x + 5
Step-by-step explanation:
20 = 8x + 4y
subtract 8x from both sides
4y = -8x + 20
divide both sides by 4
y = -2x + 5
The value of y is 5-2x=y
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 20 = 8x + 4y
Twenty equal to eight times of x plus four times of y.
We need to solve the equation for y.
To solve this we need to separate the variable y.
Subtract 8x on both sides
20-8x=4y
Divide both sides by 4
20/4-8/4x=y
5-2x=y
Hence, the value of y is 5-2x=y

If m DGE=52 and FGE is a right angle, what is the measure of DGF
Answers
Answer:
DGF=38
Step-by-step explanation:
FGE is the total angle that adds up to 90 degree. We know that it is bisected into 2 separate angles where we know DGE is 52 but not DGF.
We use the following information above to make the equation x + 52 = 90 (x represent the unknown degree)
Then you just solve normally where you subtract 53 from 90 and get the solution of x=38.

Step-by-step explanation:
Scientific notation is used to shorten numbers that are either very large or small, so negative and positive aren't really relevant answers.
Now you have to determine if the number 9.3 x 10^-8 is very large or small.
When dealing with scientific notation, a negative exponent means the number was originally a decimal and a positive exponent means the number was very large. The exponent is negative 8 so it is very small.
0.023 = 2.3 x 10^-2
2300. = 2.3 x 10^3

An airplane lands on a runway with a velocity of 150 m/s. How far will it travel until it stops if its rate of
deceleration is constant -3m/s2?
Answers
Answer:
3750 m
Step-by-step explanation:
This question can be solved using law of equation of motion
[tex]v^2 = u^2 + 2as[/tex]
where v is the final velocity
u is the initial velocity
a is the acceleration
and
s is the distance travelled
________________________________
given
final velocity = v = 0 since it is given that plane stops
u = 150 m/s
a = -3m/s2
using the above values in the given equation
[tex]v^2 = u^2 + 2as\\0 = 150*2 + 2*-3s\\0 = 22500 - 6s\\=> 6s = 22500\\=> s = 22500/6 = 3750[/tex]
Thus, plane will travel 3750 m before it stops.

Vannorman Corporation processes sugar beets in batches. A batch of sugar beets costs $78 to buy from farmers and $18 to crush in the company's plant. Two intermediate products, beet fiber and beet juice, emerge from the crushing process. The beet fiber can be sold as is for $25 or processed further for $16 to make the end product industrial fiber that is sold for $57. The beet juice can be sold as is for $39 or processed further for $22 to make the end product refined sugar that is sold for $84. How much profit (loss) does the company make by processing one batch of sugar beets into the end products industrial fiber and refined sugar?
Answers
Answer:
Results are below.
Step-by-step explanation:
We will take into account the differential costs only. Therefore, the costs of sugar beets and to crush them are irrelevant to decision making.
Beet fiber:
Sold as is= $25
Continue processing= 57 - 16= $41
It is more convenient to process further the beet fiber.
Beet juice:
Sold as is= $39
Continue processing= 84 - 22= $62
It is more convenient to process further the beet juice.
