What is function?A function is defined as a relationship between a set of inputs, each of which has a single output. Simply put, a function is a relationship between inputs, where each input is associated with exactly one output. Each function has a domain name and a code domain or region. A function is usually denoted by f(x), where x is the input. The general representation of a function is y = f(x).
There are several different types of functions in mathematics.

The Quick Ship company uses the function C(w) to calculate the cost in dollars, C, for shipping an item
weighing w ounces.
5 0.450 if 0
C(w) =
0.35W + 1.6 if w > 16
Which statement about the shipping rate is true?
Shipping at the second rate will always cost $1.60 more than shipping
at the first rate.
If the weight is greater than 16 ounces, the shipping rate is $0.35 per
ounce, plus $1.60.
It is possible that an item weighing less than 16 ounces could cost the
same as an item weighing more than 16 ounces.

To find the charge for shipping a package weighing more than
16 ounces multiply the weight by $0.35.
+
Answer:
A: Shipping at the second rate will always cost 1.60 more than shipping at the first rate.
Step-by-step explanation:
The following points for the function C(w) can be concluded as
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that the Quick Ship company uses the function C(w) to calculate the cost in dollars {C} for shipping an item weighing {w} ounces as
C(w) = 0.35W + 1.6 if {w > 16}
The given function is -
C(w) = 0.35w + 1.6 if {w > 16}
We can conclude the following points for the function C(w) -
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.Therefore, the following points for the function C(w) can be concluded as
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.To solve more questions on algebraic expressions, visit the link below -

Find the distance along an ark on the surface of the earth that subtends a central angle of 10 minutes (1 minutes 1/60 degree) The radius of the earth is 3960 miles around to the thousands
Answer:
11.52 miles
Step-by-step explanation:
We know that the length of an arc L = Ф/360 × 2πR where Ф = angle subtended by arc and R = radius of circle.
Now since Ф = 10 minutes = 10 × 1 minute = 10 × (1/60)° = (1/6)° and R = radius of earth = 3960 miles
So L = Ф/360 × 2πR
= (1/6)°/360 × 2π(3960 miles)
= 1/2160 × 7920π
= 3.67π
= 11.52 miles

What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the number of days to repair 8 km be represented as A
Now , the proportion will be
Let the distance be = 1250 meters = 1.250 km
The number of days to repair 1.250 km is = 5 days
Substituting the values in the equation , we get
5 / 1.250 = A / 8
Multiply by 8 on both sides of the equation , we get
A = ( 8 x 5 ) / 1.25
A = 40 / 1.25
A = 32 days
Hence , the number of days is 32 days

what is
the equation of the line that passes through the points (-6,6) and (-1,-9)
Answer:
The answer to the question provided is y = -3x - 12.
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ☟
[tex]y = mx + b[/tex]

[tex]m = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]
➊ First: We are going to be solving for the slope.
[tex]m = \frac{ - 9 - 6}{ - 1 - ( - 6)} = \frac{ - 15}{ \: \: \: 5} = - 3[/tex]
➋Second: We find the y-intercept.

What is the image point of (7,-7) after a translation of 3 right and 1 down followed by
a reflection over the x-axis?
Answer:
The image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:
P''(10, 8)Step-by-step explanation:
Given the point
(7, -7)
Translation of 3 right and 1 down means we need to add 3 units to the x-coordinate and subtract 1 unit from the y-coordinate
Therefore, the translation rule:
(x, y) → (x+3, y-1)
In our case, let the point P(7, -7)
P(7, -7) → P'(7+3, -7-1) → P'(10, -8)
FOLLOWED BY A reflection over the x-axis
We know that the rule of reflection over the x-axis implies that
(x y) → (x, -y)
i.e. the x-coordinate of the point remains the same, but the y-coordinate changes its sign.
After the first transformation, we had got P'(10, -8)
so
P'(10, -8) → P''(10, -(-8)) → P''(10, 8)
Therefore, the image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:
P''(10, 8)2(2)+5(3)^0

What is 524 rounded to nearest 10
Answer:
520
Step-by-step explanation:
When rounding to the nearest ten, like I did with 524 above, we use the following rules:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.

The angle of a quadrilateral are in the ratio 4:6:3 and it's fourth angle is 100. Find the other three angles of the quadrilateral
Step-by-step explanation:
Sum of angles in a quadrilateral = 360°
Sum of first 3 angles = 360° - 100° = 260°.
260° / (4 + 6 + 3) = 20°.
First angle = (20°) * 4 = 80°
Second angle = (20°) * 6 = 120°
Third angle = (20°) * 3 = 60°
The angles are 80°, 120° and 60°.
Answer:
Let the angles of the quadrilateral be 4x, 6x, and 3x
Sum of the interior angles of a quadrilateral is 360°.
According to the above problem,
[tex]4x + 6x + 3x + 100 = 360 \\ 13x = 360 - 100 \\ 13x = 260 \\ \boxed{x = 20}[/tex]
1st angle=4x=4×20=80°2nd angle=6x=6×20=120°3rd angle=3x=3×20=60°Hence, the other three angles are 80°, 120° and 60°.
