at an airport it costs $7 to park for up to one hour and $5 per hour for each additional hour. let x represent the number of hours parked. write the function that modles the cost, C(x), of the parking x hours, where x is an integer greater then 1.
Answers
Answer:
C(X) = 7 + 5(X-1)
Step-by-step explanation:
So, the cost for parking from 0 to 1 hour is $7. Then, for one extra hour, from 1 to 2, you have to pay an additional $5. For another hour, from 2 to 3, an extra $5, and so on. So, lets make a quick table:
Hours Cost
[0-1] $7
(1-2] $7+$5
(2-3] $7+$5+$5
(3-4] $7+$5+$5+$5
So, for 1 hour the cost is $7, for 2 hours $12, 3 hours $17, 4 hours $22, and so on. We can see a pattern here: the cost for X hours is $7 plus $5 for each hour greater than 1. So we can write the cost function as:
C(X) = 7 + 5(X-1)
If X=2, 2 hours, the cost is:
C(2) = 7 + 5(2-1) = 7 + 5 = 12, so the function fits.
Notice that here I used the parenthesis in a (--] form, however, it could also be used in a [--) form. If the last is chosen, 2 hours would cost $17 instead of $12. The function would be C(X) = 7 + 5X.
As the statement does not specifies, any of this ways can be used.

the function f(x) varies inversely with x and f(x) = 0.2 when x = 0.4.
what is f(x) when x = 1.6
Answers
f(x) = k/x
There is always a constant of variation , k to solve for using the given information. when x = 0.4 ; f(x) = 0.2
0.2 = k/0.4
0.2(0.4) = k
0.08 = k
final equation : f(x) = 0.08/x
when x = 1.6
f(x) = 0.08/1.6
f(x) = 0.05
if 12 newborn babies are randomly selected, how many different gender sequences are possible?
Answers
The question concerns the different combinations or sequences possible in a group of 12 newborn babies, each of whom could be either male or female. Using the formula 2ⁿ, where n represents the number of babies, we find there are 4096 different gender sequences possible.
Explanation:This question pertains to combinations, specifically the different combinations of male and female sequences possible with a random selection of 12 newborn babies. When considering gender sequences, we have two possibilities for each newborn, male (M) or female (F).
With 12 newborns, each having two possible genders, we calculate the total gender sequences as 2 raised to the power of 12, based on the rule of the product in probability theory. Therefore, we use the formula 2n, where 'n' is the number of babies. Here, 'n' is 12, so 212 gives us 4096.
So, there are 4096 different gender sequences possible when 12 newborn babies are randomly selected.

Answers
Final answer:
The coordinates of point p corresponding to t = 2 on the specified parametric curve, when matching the arc of the parabola 16y = x^2, are (8, 2).
Explanation:
The student is asking to find the coordinates of the point p corresponding to t = 2 on the curve defined parametrically by ct, [tex]c^2/16[/tex] × [tex]t^2[/tex] where c is chosen such that the curve becomes the arc of the parabola 16y = x² from (0, 0) to (8, 4).
To find c, we match the parametric equations to the standard form 16y = x², which implies c = 4 because for any point (x, y) on the parabola, y must equal [tex]x^2/16[/tex].
Substituting t = 2 into the corrected parametric equations x = 4t and y = 4 · [tex](t^2/16)[/tex], we obtain the coordinates of point p as (8, 2).

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Melina walked 9/12 mile day.
If she walked 5 days then she covers
= 5 x 9/12
= 45/12
=15/4

Solve for x and y.
y=x^2-5x+1
x+y=-2
Answers
x + y = -2
substitute the first equation into the second one....
x + x² - 5x + 1 = -2
x² - 4x + 1 = -2
add 2 on both sides to make the equation equal to 0.
x² - 4x + 3 = 0
factor this.
(x - 1)(x - 3) = 0
x = 1 , x = 3
to find the y values, you would have to substitute x = 1 and x = 3.
1 + y = -2 3 + y = -2
y = -3 y = -5
So your answers are
x = 1 , x = 3
y = -3, y = -5

Write a polynomial expression for the perimeter of a rectangle whose sides have the following lengths. Length: x2+3x-5 Width: 3x2-2x+6 A. 8x2+8x+2 B.8x2+2x+2 C.4x2+x+1 D. 4x2-5x+1
Answers
Final answer:
The perimeter of the rectangle with given dimensions is represented by the polynomial 8x^2 + 2x + 2, which corresponds to option A.
Explanation:
To determine the perimeter of a rectangle, we need to add up all sides of the rectangle. The formula for the perimeter (P) of a rectangle is P = 2(length) + 2(width). Given the length is x2 + 3x - 5 and the width is 3x2 - 2x + 6, we would calculate the perimeter as follows:
P = 2(x2 + 3x - 5) + 2(3x2 - 2x + 6)
Expanding this expression:
P = 2x2 + 6x - 10 + 6x2 - 4x + 12
Combining like terms gives us:
P = (2x2 + 6x2) + (6x - 4x) + (-10 + 12)P = 8x2 + 2x + 2
So the correct polynomial expression for the perimeter of the rectangle is option A: 8x2 + 2x + 2.
Final answer:
The polynomial expression for the perimeter of the rectangle with given side lengths is 8x^2 + 2x + 2.
Explanation:
The perimeter of a rectangle is given by the formula P = 2l + 2w, where l represents the length and w represents the width. For the lengths provided, the length (l) is x2 + 3x - 5 and the width (w) is 3x2 - 2x + 6. To find the polynomial expression for the perimeter, we will multiply both the length and the width by 2 and then sum them:
Perimeter (P) = 2(x2 + 3x - 5) + 2(3x2 - 2x + 6)
On simplifying:
P = 2x2 + 6x - 10 + 6x2 - 4x + 12
P = (2 + 6)x2 + (6 - 4)x - (10 - 12)
P = 8x2 + 2x + 2
Therefore, the correct polynomial expression for the perimeter is 8x2 + 2x + 2, which corresponds to option B.
the area of a rectangle is text square and the length of the rectangle is 3 ft more than twice the width. find the dimensions of the rectangle length and width
Answers
Let the Width of rectangle is x feet.
Length of rectangle is 3 feet more than twice the width.
Thus,Length can be written as: 2x + 3
Area of rectangle is product of its length and width.
So,
Area = Length x Width
[tex]35 = x (2x + 3) \\ \\ 35 = 2 x^{2} +3x \\ \\ 2 x^{2} + 3x - 35 = 0 \\ \\ 2 x^{2} + 10x - 7x - 35 =0 \\ \\ 2x (x + 5) - 7 (x+5) = 0 \\ \\ (2x-7)(x+5)=0[/tex]
Thus
x = -5
or
x =7/2 = 3.5
Since the measure of width cannot be negative, we neglect x = -5. and keep the value x = 3.5
Therefore,
Width = 3.5 feet
Length = 2x + 3 = 2(3.5) + 3 = 10 feet
Samantha had 300 beads 30% were black 25% were red 15% were white.the remaining beads are blue. how many were blue?

Answers
Social networking websites helps in communication and making friends , but cannot help in overcoming shyness
What is Shyness ?Shyness is a part of human behaviour that inhibits people who are shy to interact freely with people , It is a kind of fear to meet and be around new people.
Social Media has helped the shy people to be able to interact with new people without actually seeing them or meeting them ,
It has become a getaway from actually meeting people face to face , most of the feelings are communicated through messages.
The research that they have lower self-esteem than those who do not use social networking sites is true because actually making new friends in the actual world help you build confidence and makes you overcome shyness.
Social media is helping shy people but keeping them shy and so they never overcome the behaviour and in long run are still unable to talk to people and thus have low self esteem.
From this it can be concluded that for shy people , Social networking websites helps in communication and making friends , but cannot help in overcoming shyness.

Jenny's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Jenny 5.25
per pound, and type B coffee costs 4.15
per pound. This month, Jenny made 150
pounds of the blend, for a total cost of
642.60. How many pounds of type B coffee did she use?
Answers
Given that type A coffee costs $4.15 per pound
(4.15x)
Given that type B coffee costs $5.25 per pound
(5.25y)
And that the total cost of it all was $642.60
[tex]4.15x + 5.25y = 642.60[/tex]
Also, the amount of pounds, represented by x and y add up to 150 pounds total:
[tex]x + y = 150[/tex]
A=167lbs-B
$4.35A+$5.70B=$846.60 Substitute for A
$4.35(167lbs-B)+$5.70B=$846.60
$726.45-$4.35B+$5.70B=$846.60 Subtract $726.45 from each side.
$1.35B=$120.15 Divide each side by $1.35.
B=89 lbs
ANSWER: The mix contained 89 pounds of Type B coffee.
CHECK:
167lbs-89lbs=78 lbs She used 78 pounds of Type A coffee.
$4.35A+$5.70B=$846.60
$4.35(78)+$5.70(89)=$846.60
$339.30+$507.30=$846.60
$846.60=$846.60
