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
(

)
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.

Answers
Depreciation for 1st year = 20/100 × 64000 = $12800
End of 1st year = $64000 - $12800 = $51200
Depreciation for 2nd year = 10/100 × 51200 = $5120
End of 2nd year = $51200 - $5120 = $46080
Answer:
Value at the end of the 2nd year is $46,080
Answer:
Value at the end of the 2nd year is $46,080
Step-by-step explanation:
Depreciation for 1st year = 20/100 × 64000 = $12800
End of 1st year = $64000 - $12800 = $51200
Depreciation for 2nd year = 10/100 × 51200 = $5120
End of 2nd year = $51200 - $5120 = $46080

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.

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.

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.

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
