The cost of the two shipping options be the same when B. a package that weighs 7 pounds will cost $17 for both options.
What is an equation?A mathematical equation is the statement that illustrates that the variables given. In this case, two or more components are taken into consideration to describe the scenario.
The cost, y, can be represented by the equation: y = 3 + 2x,
x = the amount of pounds of the package
Another option is that the customer can pay a one-time fee of $17 to send the box, represented by the equation y = 17.
The equation will be equated together.This will be:
3 + 2x = 17
Collect like terms
2x = 17 - 3
2x = 14
Divide
x = 14 / 2
x = 7
The weight is 7 pounds.
In conclusion, the correct option is B.

License plates in a particular state are to consist of 2 digits followed by 3 uppercase letters. a) How many different license plates can there be in this state if repetition of letters and numbers is permitted? b) How many different license plates can there be in this state if repetition of letters and numbers is not permitted? c) How many different license plates can there be in this state if the must be , and repetition of letters and numbers is not permitted? d) How many different license plates can there be in this state if the first digit cannot be , and repetition of letters and numbers is not permitted?
As per the concept of probability,
a) There are 1757600 number of possible license plates can there be in this state if repetition of letters and numbers is permitted
b) There are 1404000 number of possible license plates can there be in this state if repetition of letters and numbers is not permitted.
Probability:
Probability refer the possible way of occurring the particular event.
Given,
License plates in a particular state are to consist of 2 digits followed by 3 uppercase letters.
Here we need to determine the number of possible license plates for both repetition phase and non repetition phase.
Here we know that, license plates consist of 3 letters followed by 2 digits.
Let us consider the numbers on license plates be N
Let us consider the letters on license plates be L
Then the license plate consisting of 3 letters and 2 digits will be writen as,
=> LLLNN.
We know that the letters can be anything from A to Z.
There are 26 letter combinations for the first letter.
Again second and third letters can be anything from the 26 letters.
So, combination for letters = 26 × 26 × 26 = 17576
Similarly, the numbers can be anything from 0 to 9.
There are 10 combinations for both places.
Then the combination for numbers = 10 × 10 = 100
Therefore, the total number of combination for letters and numbers
=> 17576 × 100 = 1757600.
Therefore, there are 1757600 license plates can be made with repetition.
Similarly, for non repetition mode,
The number of letters for each place is reduced before,
So, the combination for the letter is,
=> 26 x 25 x 24 = 15600
Similarly, the combination of numbers is,
=> 10 x 9 = 90
Therefore, the total number of combination is,
=> 15600 x 90 = 1404000

In this case,
[tex]y=-\frac{\sqrt[]{2}}{2}\text{ and x=-}\frac{\sqrt[]{2}}{2}[/tex][tex]\theta=\tan ^{-1}(1)=45^o,225^o[/tex]Since x is negative, and y is negative
[tex]\theta=225^o[/tex]The polar equation r = 7 sin (2theta) graphs as a rose.What is the length of the petals of this rose?Enter your answer in the box.
This problem is about a polar equation. It's important to know that polar coordinates depend on two variables, the angle of the vector and its distance.
[tex](r,\theta)[/tex]Where r represents the distance and theta represents the angles.
In this case, the angle is 20°, according to the problem.
So, first, we need to graph this equation in the polar system, to then measure the length of the petals
[tex]r=7\sin (2\theta)[/tex]The graph of this equation is shown in the image attached below.
In the image above, you can observe the polar equation graphed, with the coordinated system behind, this will allow us to find the length of each (which are symmetrical). You can observe that the petal on the third quadrant is at (-5,-5).
Now, we use the following formula to find the distance
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]Replacing the points, we have
[tex]d=\sqrt{(-5)^2+(-5)^2}=\sqrt{25+25}=\sqrt{2(25)}=5\sqrt{2}\approx7.07[/tex]Therefore, the length of each petal is 7.07 units, approximately.Translate to an equation and solve.What is 75% of 274?is 75% of 274.(Simplify your answer. Type an integer or a decimal.)

[tex]P=r\times\frac{n}{100}[/tex]Where "P" is the percentage.
Now, we substitute the given values:
[tex]P=274\times\frac{75}{100}[/tex]Solving the operations:
[tex]P=205.5[/tex]Therefore, the 75% of 274 is 205.5

a) Plot the graph of y = 2^x+2 for-4 ≤ x ≤ 4
b) Draw the asymptote.
c) Write the equation of the asymptote.
I need help with question c only
Answer:
y = 2
Step-by-step explanation:
A horizontal asymptote is a horizontal line that the graph of a function approaches as x approaches ±∞.
Mathematically we write this as
[tex]f(x) \rightarrow a \text{ as } x \rightarrow \infty \text{ or } x \rightarrow -\infty[/tex]
A vertical asymptote at some constant a is where the function approaches ±∞.
Mathematically
[tex]f(x) \rightarrow \infty \text { or } f(x) \rightarrow -\infty \text{ as } x \rightarrow a[/tex]
The given function y = 2ˣ + 2 is an exponential function and exponential functions do not have a vertical asymptote
The horizontal asymptote can be found by determining what the function limit is as [tex]x \rightarrow \pm \infty[/tex]
As [tex]x \rightarrow +\infty[/tex] the function [tex]\rightarrow \infty[/tex]
As [tex]x \rightarrow -\infty[/tex] , [tex]2^x \rightarrow 0\\\\\\2^x + 2 \rightarrow 2\\\\[/tex]
So the equation for the horizontal asymptote is y = 2
The graph shows that at y = 2, the function is parallel to the line but does not touch the line

Calculus in real life applications is highly common in the engineering industry.
Structural engineering is one of calculus' most important practical applications. Calculus is used to determine structural requirements for earthquake design, stresses in intricate structural combinations, and heat loss in buildings. Calculus is used by architects to determine the crucially critical amount of materials needed to build support systems that can endure stress for extended periods of time. Calculus was used to foresee the effects of wind resistance when building famous structures like the Eiffel Tower.
Beams, tension, and compression members are the three structural components that civil engineers must take into account while building bridges. Calculus can be used to calculate the amount of force exerted on the beam, taking into account the weight of vehicles, pedestrians, and projected traffic on the bridge. The materials, size, and capacity can be calculated based on these variables.
