c.(
c.left parenthesis, c, right parenthesis.
Answers
c= a*p
where c= cost, a= rates per hour, p= hours of parking
Alexandra pays 7$ for 3 hours parking. So, a would be:
c= a*p
7$= a * 3 hr
a= 7$/3hr
Then the final equation would be:
c= (7/3) *p
Answer:
c=7/3p
Step-by-step explanation:
Let's find the constant of proportionality.
in the proportional relationship between p, the number of hours parked, and c, the cost in dollars, one constant of proportionality is the cost per hour. It is the number we multiply by the number of hours to get the total cost.
p×?=c
px?=c
?= [tex]c/p[/tex]
= 7/3
the constant of proportionality is 7/3 this means we can multiply 7/3 by the numbers of hours to get the total cost
Now, let's write the equation: total cost
total cost=cost per hour×number of hours
[tex]c=7/3p[/tex]

Quadrilateral ABCD is inscribed in this circle.
What is the measure of angle C?
Enter your answer in the box.
Answers
For the quadrilateral ABCD and the inscribed circle, the measure of angle c will be 62⁰.
We already know that the opposite angles of an inscribed quadrilateral are supplementary in nature.
Therefore, In this problem
m<D+m<B=180⁰
m<C+m<A=180⁰
First, we have to find the value of x
m<D+m<B=180⁰
then substitute the values to solve for x, we get
(x+20)⁰ + (3x)⁰ = 180⁰
4x = 180⁰ - 20⁰
x = 160/4
x = 40⁰
second, to find the measure of angle A
m<A = (2x+38)⁰
put the value of x from first step,
angle A = 2(40)⁰+38⁰=118⁰
third, to find the measure of angle C
m<C+118⁰=180⁰
m<C = 180⁰-118⁰
angle C = 62⁰

if you reflect fgh across the y-axis, what will be the coordinates of the vertices of the image f'g'h'
Answers
The correct answer is b.
Hope this helps =)
Therefore option B is correct.
What is reflection of coordinates?When a point is reflected across the line y = x, the x-coordinates and y-coordinates change their place. Similarly, when a point is reflected across the line y = -x, the x-coordinates and y-coordinates change their place and are negated. Therefore, The reflection of the point (x, y) across the line y = x is (y, x).
We have,
Coordinate of the vertex of the ΔFGH is F( -2 , -1 ) , G( 2 , 2 ) and H( 4 , -3 )
According to the question,
We know that when a point ( x , y ) reflected over y-axis , the y-coordinate remains the same but the x-coordinate is transformed into its opposite .i.e., ( -x , y )
So, Image of the Vertex F( -2 , -1 ) = F'( -(-2) , -1 ) = F'( 2 , -1 )
Image of the Vertex G( 2 , 2 ) = G'( -2 , 2 )
Image of the Vertex H( 4 , -3 ) = H'( -4 , -3 )
Hence, the image of the vertexes is F'( 2 , -1 ) ,G'( -2 , 2 ) and H'( -4 , -3 )

What is the value of tan D?
Answers
As according to the mathematical acronym SOH CAH TOA (Sin Opposite Hypotenuse, Cos Adjacent Hypotenuse, Tan Opposite Adjacent), the correct answer would be the first choice, [tex] \frac{12}{5} [/tex].
The reason behind this is because the tangent value of an angle is always the length value opposite of given angle over the value adjacent (or right next to) the given angle.
In this case, the question is asking for Tan D. The side value opposite of angle D would be 12, and the length value that is adjacent to angle D is 5.
Therefore, the value of tan D would be [tex] \frac{12}{5} [/tex].

Batteries of each type have lifetimes before recharge that can be assumed independent and Normally distributed. The mean and standard deviation of the lifetimes of the Duxcell batteries are 10 and 2 minutes respectively, the mean and standard deviation for the Infinitycell batteries are 14 and 3 minutes respectively.
Part a) What is the probability that a Duxcell battery will last longer than an Infinitycell battery?,
Answers
X = N(10, 2^2)
This means that:
mean is 10
variance is 2^2
Y = N(14, 3^2).
Asked:P(X > Y)
= P(X - Y > 0).
mean of Z = X - Y
= 10 - 14
variance = 2^2 + 3^2
Z = N(-4, 2^2 + 3^2).
Answer:
0.1562
Step-by-step explanation:
Step 1
In this tep we define the normal distributions in this problem. . The lifetime of the Duracell battery is a normal random variable X with parameters (10,4). The lifetime of the Infinitycell battery is a normal random variable with parameters (14.9).
Step 2
Define the new normal distribution formed by the combination of these two distributions. We define a random variable Z such that
,[tex]Z=X-Y.[/tex]
This will be a random variable with mean of [tex]\mu_x-\mu_y=10-14=-4[/tex]. This random variable will have a variance of [tex]\mu_z^2 =\mu_x^2+\mu_y^2=2^2+3^2=13[/tex]. The mean for this distribution is [tex]\mu_z=\sqrt{13}[/tex] . The random variable Z is normally distributed with parameters (-4,13)
Step 3
The next step is to calculate the probability that [tex]Z=X-Y>0[/tex]. For that we perform the calculation shown below. Along the way , we will use the method of transforming any normal distribution to the standard normal distribution.This transformation is [tex]z=\frac{x-u}{\sigma}[/tex].
[tex]P(Z>0)=P(X-Y>0)=P(Z>0)\\P(Z>0)=1-P(Z<0)\\P(Z>0)=1-P(\tfrac{0-(-4)}{\sqrt{13}})=1-P(\tfrac{4}{\sqrt{13}})\\P(Z>0)=1-0.8438\\P(Z>0)=0.1562[/tex]

A regular hexagon has a perimeter of 120 m. Find its area. Leave your answer in simplest radical form.
Answers
(1/2) • a • p
Where a is the apothem (a line from the center of a side to the center of the shape) and p is the perimeter.
We have the perimeter: 120
Now to find the apothem. To find it, we’re going to cut any sidelength in half, and the line from that half to the center of the hexagon will form a right triangle. We know the bottom leg (where the shape is) is 10 (since 120/6 = 20, and we cut that in half). All we need is angles. To find the interior angle of any regular shape, we use
(180(n - 2))/n
Plugging in, we get 120 degrees for every side. Since we cut it in half, then the top angle of our right triangle is 60. You know what that means? We’ve just found a 30, 60, 90 triangle.
Using the laws of this special triangle, the length of the apothem is the shortest leg times sqrt(3)
So, 10sqrt(3) is your apothem.
Plug everything in!
(1/2) • a • P
(1/2) • 10sqrt(3) • 120

Hope it helps!(:
Answer:
1: B) $578
2: B) $25.33
3: D) $61,980
Step-by-step explanation:
1) Henry's premium = ($100,000 / $1,000) x $5.78 = $578
2) Karen's total premium = ($75,000 / $1,000) x $17.56 = $1,317
if she is paid weekly, then the premium must be divided by 52 weeks = $1,317 / 52 weeks = $25.33 deducted per week
3) Nikos's premium per year = ($300,000 / $1,000) x $10.33 = $3,099
times 20 years = $3,099 x 20 = $61,980

Part 1.] Does the graph have even symmetry, odd symmetry, or neither?
Part 2.] Does the graph of y = sin x have even symmetry, odd symmetry, or neither?
Part 3.] Identify the transformations that describe the graph of an even function. Select all that apply.
reflection over the x-axis; reflection over the y-axis; reflection over the line y=x; 90° rotation around the origin; 180° rotation around the originAnswers
The graph has even symmetry. You can see that because it is symmetric with respect to the y-axis.
Functions that have even symmetry have the following property:
[tex]f(x)=f(-x)[/tex]
Part 2
To answer this we can simply check if the property we mentioned earlier holds for this function.
[tex]sin(\frac{\pi}{2})\ne sin(-\frac{\pi}{2})[/tex]
We can see that sine does not have even symmetry.
In fact, sine function has the following property:
[tex]sin(x)=-sin(x)[/tex]
This is called odd symetry.
Part 3
Take a look at the function that you attached in the picture. We know that function has even symmetry.
Reflection over x-axis and 180° rotation around the origin would give us -f(x). We would not end up with the same function, so these two are out.
90° rotation around the origin would mean we swapped x and y so that one is out too. Reflection over the line y=x is a property of functions that have an odd symmetry.
We are left with reflection around y-axis and, as mentioned before, this is the property of evenly symmetric functions.

The answer is E.
Final answer:
The correct answer is E) 36sqrt(3), which is the volume of the described solid.
Explanation:
The student's question relates to finding the volume of a solid with unusual properties: it has a circular base and each plane cross-section perpendicular to the x-axis is an equilateral triangle. We will solve this problem using calculus, specifically by integrating the cross-sectional area along the x-axis.
The circular base of the solid defines the limits of integration, as it gives the diameter of the solid which, in turn, represents its height because the triangle is equilateral.
The radius given is 3, so the diameter (and hence the height of the solid) is 6.
The area of an equilateral triangle with side length s is (sqrt(3)/4) * s².
Since the side length of the triangles is equal to the diameter of the base, s is 6.
Therefore, the area of each cross-section is (sqrt(3)/4) * 6².
Now, to find the volume, we integrate the area of each cross-section along the height of the solid. Doing this gives us:
Volume = [tex]int_0^6 ((sqrt(3)/4) * 6^2) dx[/tex]= (sqrt(3)/4) * 36 * 6
= 6*6*6*sqrt(3) / 4
= 36sqrt(3)
Thus, the correct answer is E) 36sqrt(3), which is the volume of the described solid.

Answer:

: n=1
ii.the upper limit of the sum
: n=18
iii.the explicit formula of the sum
: [tex]a_n=7n-4[/tex]
b) 1,125 beads
Step-by-step explanation:
a) The number of beads per row of Dante's necklace is given by the series:
3 + 10 + 17 + 24 + ...
The first term of this series is [tex]a_1=3[/tex].
There is a constant difference of [tex]d=10-3=7[/tex].
To write this series in summation notation, we need to determine the explicit formula which is given by:
[tex]a_n=a_1+d(n-1)[/tex]
We plug in the values to get:
[tex]a_n=3+7(n-1)[/tex]
[tex]\implies a_n=3+7n-7[/tex]
[tex]\implies a_n=7n-4[/tex]
The summation notation is given by:
[tex]\sum^{18}_{n=1}(7n-4)[/tex]
b) The total number of beads in the necklace is given by the sum of the first 18 terms of the sequence.
This is given by [tex]S_n=\frac{n}{2}(2a_1+d(n-1))[/tex]
We substitute the values to obtain:
[tex]S_{18}=\frac{18}{2}(2\cdot3+7(18-1))[/tex]
[tex]S_{18}=9(6+119)[/tex]
[tex]S_{18}=9(125)[/tex]
[tex]S_{18}=1125[/tex]
Therefore the total number of beads is 1125
The arithmetic series 3, 10, 17, 24,... in which each term increases by 7 can be described in summation notation with a lower limit of 1, an upper limit of 18, and an explicit formula of 7n - 4. The total number of beads in Dante's 18-row necklace, computed using the arithmetic series sum formula, is 1125 beads.
Explanation:The series described here is an arithmetic series, where each term increases by the same amount, 7 in this case.
a. To express this series in summation notation, you must know:
The lower limit of the sum: In the series, the first term is 3, so the lower limit, often denoted as n, is 1.The upper limit of the sum: As there are 18 rows, n, or the number of terms in our sum, will be 18.The explicit formula for the sum: For an arithmetic series, the sum is given by the formula S = n/2 * (a + l) where n is the number of terms, a is the first term and l is the last term. However, we need the general term to express the series in summation notation, which is given by a + (n-1)d in an arithmetic progression. Here, a=3 and d, the difference is 7. So the general term is 3 + (n-1)*7 = 7n - 4.b. To find the total number of beads in the necklace, you use the formula for the sum of an arithmetic series. For the last term, l, we use the formula a+(n-1)d = 3+(18-1)*7 = 122. Hence, the total number of beads is S = 18/2 * (3 + 122) = 1125.

Answer:
The correct option is D. social security number
Step-by-step explanation:
Address : Address cannot do much harm in the case of identity theft because other identity related information cannot be stolen by using the address.
So, this option is rejected.
Date of Birth : By using date of birth, no information about anyone's personal identity can be found. So this also cannot be related to identity theft.
So, this option is also rejected.
Mother's maiden name : This option is also not helpful in case of identity theft as this will not give any valuable information about someone's identity.
So, this option is also rejected.
Social security number : This number holds every personal information about a person so by using this complete identity of a person can be accessed and will present the greatest risk for identity theft.
Hence, The correct option is D. social security number
