The table

weeks. If the pattern continues, what
will Henry's savings be in Week 10? Tell
how you know.
Week

23
Savings
$6.50
$7.50
$8.50
$9.50
Henry's savings in Week 10 would be $\(15.50\).
Based on the given information, Henry's savings appear to be increasing by $\(1.00\) every week. The pattern suggests that there is a constant increment of $\(1.00\) in the savings amount from week to week.
To find Henry's savings in Week 10, we can use the following formula for an arithmetic sequence:
\(\[ a_n = a_1 + (n-1)d \]\)
where \(a_n\) represents the nth term, \(\(a_1\)\) is the initial term, \(\(n\)\) is the position of the term, and \(d\) is the common difference.
In this case, the initial term \(a_1\) is $\(6.50\) and the common difference \(\(d\)\) is $1.00. Substituting these values into the formula, we can find Henry's savings in Week 10 \((\(a_{10}\))\):
\(\[ a_{10} = $6.50 + (10-1) \times $1.00 \]\[$6.50 + 9 \times $1.00 \] $6.50 + $9.00 \]\\ $15.50 \]\)
Therefore, if the pattern continues, Henry's savings in Week 10 would be $\(15.50\).

Find the equation in standard form of the circle with center at (4, −1) and that passes through the point (−4, 1).
Answer:
The standard form of the equation of a circle with center at (h, k) and radius r is:
(x - h)^2 + (y - k)^2 = r^2
We are given that the center of the circle is (4, -1), so h = 4 and k = -1. We also know that the circle passes through the point (-4, 1), which means that the distance from the center of the circle to (-4, 1) is the radius of the circle.
The distance between two points (x1, y1) and (x2, y2) is given by the distance formula:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
So the radius of the circle is:
r = sqrt((-4 - 4)^2 + (1 - (-1))^2) = sqrt(100) = 10
Now we can substitute the values of h, k, and r into the standard form equation of a circle:
(x - 4)^2 + (y + 1)^2 = 10^2
Expanding the equation gives:
x^2 - 8x + 16 + y^2 + 2y + 1 = 100
Simplifying and putting the equation in standard form, we get:
x^2 + y^2 - 8x + 2y - 83 = 0
Therefore, the equation in standard form of the circle with center at (4, −1) and that passes through the point (−4, 1) is:
x^2 + y^2 - 8x + 2y - 83 = 0
The radius of curvature of a rear- view mirror in a car is 4m. If a truck is behind the car, located 5m from the rear-view mirror of the car. Calculate the size of the image relative to the size of the truck and also find the position and nature of the image formed.
Answer:
Step-by-step explanation:The car will appear to be 0.8 m behind the mirror.
Answer:
The size of the image is 4/9 times larger than the actual size of the truck.
the image is magnified and virtual
Step-by-step explanation:
We can use the mirror formula to find the position and nature of the image formed by the rear-view mirror in the car:
1/f = 1/u + 1/v
where:
f = radius of curvature of the mirror = 4m (given)
u = distance of the object (the truck) from the mirror = -5m (negative sign indicates that the object is behind the mirror)
v = distance of the image from the mirror (positive sign indicates that the image is in front of the mirror)
Substituting the given values, we get:
1/4 = 1/-5 + 1/v
Simplifying this equation, we get:
v = m
v=20/9 m
This means that the image of the truck is formed at a distance of 20/9meters from the rear-view mirror, behind the driver's seat.
To find the size of the image relative to the size of the truck, we can use the magnification formula:
m = v/u
Substituting the values we get:
m =(-20/9) / (-5) = 4/9
This means that the image of the truck formed by the rear-view mirror in the car is 4/9 times larger than the actual size of the truck.
So, the image is magnified and virtual (since the image is formed behind the mirror), and its distance from the mirror is 20/9 meters. The size of the image is 4/9 times larger than the actual size of the truck.

The exponential function that represents this situation is 25000(1.03)ˣ
Writing the exponential function that represents this situation.From the question, we have the following parameters that can be used in our computation:
Inital visitors, a = 25000
Rate of increase, r = 3%
Using the above as a guide, we have the following:
The function of the situation is
f(x) = a * (1 + r)ˣ
Substitute the known values in the above equation, so, we have the following representation
f(x) = 25000 * (1 + 3%)ˣ
So, we have
f(x) = 25000(1.03)ˣ
Hence, the function is 25000(1.03)ˣ

The diagonal BD represents the magnitude and direction of the resultant force.
To find its magnitude, we use the Law of Cosines:
BD^2 = AB^2 + BC^2 - 2(AB)(BC)cos(θ)
BD^2 = (7 lb)^2 + (11 lb)^2 - 2(7 lb)(11 lb)cos(133 degrees)
BD^2 = 49 + 121 - 2(77)cos(133 degrees)
BD^2 = 170 - 154cos(133 degrees)
BD ≈ 9.07 lb (rounded to two decimal places)
Therefore,
The magnitude of the resultant force is approximately 9.07 lb.

A sorting algorithm is defined as an algorithm that sorts the elements of a list. The most commonly used sequences are numerical sequence and lexicographical sequence, ascending or descending.
A sorting algorithm is used to reorder an array or list of elements according to an element comparison operator. Comparison operators are used to define a new order of elements in that data structure. Consider example, The above list of characters is sorted in ascending order by their value. That is, characters with lower values are placed before characters with higher values. It is important in real life because it supports the development of the scientific concept that things can be owned and organized into distinct groups (e.g. creatures, cars, weather types, etc.). We will now discuss some real-world examples of using sorting algorithms.
1) Your phone's contact list is sorted. This means that your data is organized in this way so you can easily access the contacts you want from your phone. That is, "I ordered."
2) Paper sorting : Imagine a teacher sorting students' work alphabetically by student name. This type of operation is similar to the functionality of sorting algorithms such as bucket sort. Sorting is more efficient process.
3) Traffic lights : Traffic lights are a good example of how algorithms are used in the real world around us. Next time you get stuck in a car at a red light, think about the algorithm that traffic lights run." Most traffic lights don't automatically switch between green, yellow, and red. This algorithm is a well-established turn-by-turn algorithm that directs traffic correctly. It's in order (it may not seem that way when you're sitting at a red light).

An airplane has an airspeed of 528 mi/hr bearing 25° west of north. Which of the following vectors best describes the path of the airplane? O v= 528 cos(155°)i + 528 sin(1550); O v = 25 cos(528°)i + 25 sin(528°); O None of these O v = 528 cos(25°)i + 528 sin(259); O v = 528 cos(115°)i + 528 sin(115)
An airplane has an airspeed of 528 mi/hr bearing 25⁰ west of north. The path can be described as a vector v = (528 cos 115⁰) i + (528 sin 115⁰) j
Suppose we have a vector with magnitude v and angle α with the positive x-axis, then the vector can be expressed as its component as:
vx = v cos α
vy = v sin α
or
v = vx i + vy j
v = (v cos α) i + (v sin α) j
In the given problem, the magnitude is 528, while the angle is:
α = 25⁰ west of north = 25⁰ + 90⁰ = 115⁰
Hence,
vx = 528 cos 115⁰
vy = 528 sin 115⁰
v = (528 cos 115⁰) i + (528 sin 115⁰) j
