An integer leaves a remainder 1 when divided by 4. What is the remainder when the square of this integer is divided by 8?
PLSS HELP ASAP
Answer:
Let's suppose that the integer is x.
We know that x leaves a remainder of 1 when divided by 4, so we can express x as:
x = 4n + 1
where n is some integer.
Now we need to find the remainder when x^2 is divided by 8:
x^2 = (4n + 1)^2
x^2 = 16n^2 + 8n + 1
Notice that the first two terms (16n^2 + 8n) are divisible by 8, so we can ignore them.
The remainder when x^2 is divided by 8 is the same as the remainder of 1 when divided by 8:
x^2 ≡ 1 (mod 8)
Therefore, the remainder when the square of the integer is divided by 8 is 1.

What is the parabola?
The parabola is the locus of points in that plane that are equidistant from both the directrix and the focus. Another description of a parabola is as a conic section, created from the intersection of a right circular conical surface and a plane parallel to another plane that is tangential to the conical surface.
Option A is the correct equation in vertex form for the function:
g(x) = 2(x-5)² + 9
The vertex form of a parabola is y=a(x-h)²+k, where (h,k) is the vertex of the parabola. We are given that the vertex is located at (5,9), so h=5 and k=9. Substituting these values into the vertex form equation, we get:
g(x) = a(x-5)² + 9
To find the value of a, we can use one of the points that the parabola passes through. Let's use point (7,1):
1 = a(7-5)² + 9
1 = 4a + 9
-8 = 4a
a = -2
Substituting this value of a into the equation, we get:
g(x) = -2(x-5)² + 9
Expanding the square and simplifying, we get:
g(x) = -2x² + 20x - 41
This is not in vertex form, but if we factor out the -2 from the first two terms, we get:
g(x) = -2(x² - 10x + 20.5)
Completing the square inside the parentheses, we get:
g(x) = -2(x-5)² + 50.5
This is also in vertex form, but the constant term is not 9 as given in the problem.
Therefore, the correct equation in vertex form for the function is:

two pairs of hikers leave the same camp heading in opposite divections. Each travels 2 miles, then changes direction and travels 1.2 miles. The first pair starts due east and then turns 50° toward north. The second pair starts due west and then turns 40° toward south. Which pair is farther from camp? Explain your reasoning.
Answer:
As a result, the first pair of hikers is around 0.15 miles further away from camp than the second pair.
Step-by-step explanation:
Let's designate "x" for the distance travelled directly east or west and "y" for the distance directly north or south. Then, using the method below, determine how far each pair of hikers is from camp:
Distance is equal to sqrt(2xy*cos(angle) - xy + yy).
where "angle" is the angle at which the hikers veer away from their original path.
The first group of hikers includes:
Distance is equal to sqrt(((2cos(50°) + 1.2sin(50°))).
(1.2cos(50°) + 2 sin(50°))
(1.2sin(50°) + 2cos(50°)) = 2 - 2*
(1.25*cos(50°) + 1.2*cos(50°)*cos(130°))
approximately 2.53 miles.
The second group of hikers includes:
Distance is equal to sqrt(((2cos(40°) + 1.2sin(40°))).
-2sin(40°) + 1.2cos(40°) = 2
(1.2sin(40°) + 2cos(40°)) = 2 - 2*
(-2sin(40°) plus 1.2*cos(40°)*cos(140°))
about 2.38 miles.
As a result, the first pair of hikers is around 0.15 miles further away from camp than the second pair.

What is area?
An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.
Let's call the length of the rectangle "l" and the width "w".
We can write two equations based on the given information -
Perimeter equation: 2l + 4w = 600 (since there are two sets of parallel sides, we have to add an extra "w" to the perimeter equation)
Area equation: A = 3lw (since the field is divided into 3 equal parts)
We want to maximize the enclosed area, which means we want to find the values of "l" and "w" that make the area as large as possible.
We can use the perimeter equation to solve for one of the variables in terms of the other -
2l + 4w = 600
2l = 600 - 4w
l = 300 - 2w
Now we can substitute this expression for "l" into the area equation -
A = 3lw
A = 3(300 - 2w)w
A = 900w - 6w²
To find the maximum area, we can take the derivative of this equation with respect to "w" and set it equal to zero -
dA/dw = 900 - 12w = 0
12w = 900
w = 75
So the width of each of the smaller rectangular plots is 75 feet. We can use the perimeter equation to find the length -
2l + 4w = 600
2l + 4(75) = 600
2l = 300
l = 150
Therefore, the dimensions value are obtained as 150 feet by 75 feet.

Construct a data set consisting of 10 values that has a mean of 9, a median of 8, a mode of 5, and a midrange of 11.5. List the data values in ascending order.
Answer:
Step-by-step explanation:
To construct the data set, we need to consider the given measures of central tendency:
Mean: 9
Median: 8
Mode: 5
Midrange: 11.5
We can start by finding five values that are less than or equal to the median of 8, and five values that are greater than or equal to the median. Since the mode is 5, we can include it as one of the lower values.
Let's try to find the other four lower values that satisfy the given conditions:
The sum of all values is 10 * 9 = 90 (since there are 10 values and the mean is 9).
The mode is 5, so we need at least two values that are equal to 5.
The midrange is (max + min) / 2 = 11.5, so we need a maximum value that is 3 more than the minimum value.
Here's one possible set of 10 values that satisfy these conditions, listed in ascending order:
{2, 3, 4, 5, 5, 8, 9, 10, 12, 13}
To check that this set of values satisfies the given conditions:
The mean is (2+3+4+5+5+8+9+10+12+13) / 10 = 9.
The median is 8 (the middle value when the values are listed in ascending order).
The mode is 5 (the most common value).
The midrange is (13 + 2) / 2 = 7.5 + 4 = 11.5 (the average of the maximum and minimum values).
Jayla plays on the Strikers soccer team. The team worked on 5 new drills at yesterday's
practice, spending the same amount of time on each drill. Jayla was 15 minutes late and only
practiced for 40 minutes.
) Which equation can you use to find how long, x, the team spent on each drill?
Answer:
Let's use "d" to represent the time the team spent on each drill.
Since the team spent the same amount of time on each drill, and they worked on 5 drills, the total time spent at practice before Jayla arrived can be represented as:
5d
We know that Jayla was 15 minutes late, so when she arrived, the team had already been practicing for 15 minutes. Therefore, the total time she spent practicing is:
40 minutes = 5d - 15
Now we can solve for "d":
5d - 15 = 40
5d = 55
d = 11
So the team spent 11 minutes on each drill.
The equation we used is:
5d - 15 = 40

The length of the most direct path between Ann and the pile of bottle caps is given as follows:
31 feet.
What is the distance between two points?Suppose that we have two points with coordinates [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex].
The shortest distance between them is given by the equation presented as follows:
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Ann's location is given by the following ordered pair:
(-4,3).
The location of the pile of bottle caps is given by the following coordinate pair:
(4, -10).
Hence the distance is given as follows:
D = sqrt((4 - (-4))^2 + (-10 -3)^2)
D = 15.5 units.
Each unit represents 2 feet, hence:
15.5 x 2 = 31 feet.
