The distance between the two points P1 and P2 is d = √61.
What is the distance?Distance is a measurement of how far apart two objects or points are, either numerically or occasionally qualitatively. The distance can refer to a physical length in physics or to an estimate based on other factors in common usage. Length is measured in distance. For instance, the length of a road is its distance. The most popular units of measurement for distance in the metric system are millimeters, centimeters, meters, and kilometers.So, the distance between points P1 and P2:
Where, P1 = (0,0) and P2 = (6,5).The distance formula: d = √(x₂-x₁)²+(y₂-y₁)²Now, substitute the values in the formula as follows:
d = √(x₂-x₁)²+(y₂-y₁)²d = √(6-0)²+(5-0)²d = √36+25d = √61Therefore, the distance between the two points P1 and P2 is d = √61.

Hello! Need some help on parts a,b, &c. The question and rubric is linked below. Thank you!
Part A: -5/9, 6/10, -7/11, 8/12
Part B:
[tex]f(n)=(-1)^{n}(\frac{n}{n+4})[/tex]Part C: Positive
Explanation:The given sequence is:
[tex]-\frac{1}{5},\frac{2}{6},-\frac{3}{7},\frac{4}{8},....[/tex]As seen above the sequence is an alternating sequence because it changes in sign
Also, neglecting the sign chnages, we will observe, a common diffference of 1 in the numerator and denominator
a) Therefore, if the pattern continues, the next 4 terms in the sequence are:
-5/9, 6/10, -7/11, 8/12
b)
Without the sign, the explicit equation representing the numerator is calculated below:
1, 2, 3, 4......
The first term, a = 1
The common difference, d = 1
This is an arithmetic sequence
N(n) = a + (n - 1)d
N(n) = 1 + (n - 1)(1)
N(n) = 1 + n - 1
N(n) = n
The explicit equation representing the denominator is calculated below
5, 6, 7, 8........
The first term, a = 5
The common difference, d = 1
D(n) = a + (n - 1)d
D(n) = 5 + (n - 1)(1)
D(n) = 5 + n - 1
D(n) = n + 4
The alternating sequence will include the term below:
[tex](-1)^n[/tex]Therefore, the explicit equation for f(n) representing the sequence is:
[tex]f(n)=(-1)^n(\frac{n}{n+4})[/tex]Part C) The sign of f(56) will be:
(-1)^56 = 1
Since this gives us a positive value, the sign of f(56) is positive

Given that a function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, select the statement that could be true for g. A. g(-4) = -11 B. g(-13) = 20 C. g(7) = -1 D. g(0) = 2
The true statement is g(-13)= 20.
What is domain and range?In mathematics, a function is represented as a rule that produces a distinct result for each input x. Mapping or transformation is used to denote a function in math. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
domain = -20 ≤ x ≤ 5
and a range = -5 ≤ g(x) ≤ 45
and g(0) = -2 and g(-9) = 6
First, g(-13)= 20
x=-13 is in our domain and 20 is also in our range .
So this is true for g(-13)= 20.
Now, g(-4) = -11
-11 does not comes under the range.
So this statement is not true.
Again, g(0) = 2 is false because g(0) = - 2.
and, g(7) = -1 D
7 is not in our domain .
So g(7) is not possible

Complete question is:
The function f(x) = 600 - 100x models the value, f(x), of a video game system x years after purchase. Which choice represents the most appropriate domain of the function?
Answer and explanation:
The domain of a function is the values you can plug into the function, the possible values for x.
While x could take any value, there are a range of apropiate values that it can take.
For example, since x represents years after purchase, x can not be a negative number, because that would represent negative years, thus x must be greater or equal to 0.

Step-by-step explanation:
Given: " x³ + x⁰ " ; Evaluate for "x = 2 ".
Plug in 2 for the x values; and solve:
" 2³ + 2⁰ " ;
Note: " 2³ = 2 * 2 * 2 = 8 " ;
" 2⁰ = 1 " .
Note: Any 'non-zero' value, raised to the 'zeroth' [0°]' exponential power, is equal to 'one' [ 1 ].
So: " x³ + x⁰ = 2³ + 2⁰ = 8 + 1 = 9 ."

After solving basic fractions we have come to find that, we need 12.7 tiles to create a frieze above a Forrest.
What is fraction?When describing a portion or part of a whole in mathematics, a fraction is used. The equal components of the whole are represented by it. Both the numerator and denominator are components of a fraction.
Both the top and bottom numbers are referred to as the numerator and denominator, respectively. The denominator specifies the total number of equally sized pieces in the whole, whereas the numerator specifies the number of equal parts that were taken.
A fraction is something like 5/10.
The denominator in this case is 10, and the numerator is 5.
The measure of each tile = 2⅞
= 23/8
Measure of doorway = 36½
= 73/2
No. of tiles we need = 36½ / 2⅞
= 12.7 tiles
Thus, we need 12.7 tiles to create a frieze above a Forrest.

When riding his bike down a hill, Lance can maintain an average speed of 55.5 km/h. When riding uphill, his speed drops to an average of 24.25 km/h. On a recent ride, 28% of Lance's ride was uphill, 33% was downhill and the rest of the ride was on a mostly flat surface. If the distance he covers is 475 km, how long do you think he took to complete his ride? Show your work.
Answer:
10.59480821 hours
Step-by-step explanation:
First, we need to know the percent of the flat surface. so we are gonna add the uphill and down hill then take the sum and find the difference from 100% 28+33+x=10061+x=100[tex]\frac{61+x}{-61} =\frac{100}{-61}[/tex]x=392. Now we know the percent for each surface
Uphill = 28%Downhill = 33%Flat = 39%3. Now that we know the percent of each surface we need to find out how many km for each surface:
Uphill
0.28×475=133kmDownhill
0.33×475=153.75kmFlat
0.39×475=185.25km3. Now that we know all the percent and distance for each surface we need to know the km/h for each
Uphill = 24.25km/h
Downhill = x
Flat = 55.5km/h
4. Since we don't have the speed for downhill we need to know the difference between uphill and flat
55.5-24.25=31.255. Now we know the difference is 31.25 we can add that to the flat surface to get the downhill speed
55.5+31.25=86.75Downhill =86.75km6. Now we know all the speeds and now we can figure out how many hours it takes for each surface
( we are going to take the distance in 1 surface and then divide that by the km/h in that surface to ket how many hours)
Uphill
133÷24.25=5.484536082 hoursDownhill
153.75÷86.75=1.772334294 hoursFlat
185.25÷55.5=3.337837838 hours7. Now we add all the hours up

MATRECIES: Suppose ={u,v,w}⊆R3 is linearly independent. Determine if the set 4 ={u, v, v−w, u+v+w} is linearly independent or linearly dependent.
The set is linearly dependent.
To explicitly prove this, we need to show there is at least one choice of constants [tex]c_1,c_2,c_3,c_3\in\Bbb R[/tex] such that
[tex]c_1 u + c_2 v + c_3(v-w) + c_4(u+v+w) = 0[/tex]
or equivalently,
[tex](c_1 + c_4) u + (c_2 + c_3 + c_4) v + (-c_3 + c_4) w = 0[/tex]

[tex]\begin{cases} c_1 + c_4 = 0 \\ c_2 + c_3 + c_4 = 0 \\ -c_3 + c_4 = 0 \end{cases}[/tex]
From the first and last equations, we have [tex]c_1=-c_4[/tex] and [tex]c_3=c_4[/tex]. Substituting these into the second equation leaves us with [tex]c_2-2c_1=0[/tex], and so the overall solution set is

The image of the point P(x, y) = (4, 2) by means of a translation formula is point P'(x, y) = (- 1, 4).
What is the image of a given point after making a translation?
In this question we find the coordinates of a point set on Cartesian plane which is modified by using a translation, a kind of rigid transformation. Rigid transformations are transformations applied on geometric loci such that Euclidean distances are conserved.
Vectorially speaking, translations are described by the following formula:
P'(x, y) = P(x, y) + T(x, y)
Where:
P(x, y) - Original pointP'(x, y) - Resulting pointT(x, y) - Translation vectorIf we know that P(x, y) = (- 9, - 3) and P'(x, y) = (- 14, - 1), then the translation vector is:
T(x, y) = P'(x, y) - P(x, y)
T(x, y) = (- 14, - 1) - (- 9, - 3)
T(x, y) = (- 5, 2)
Then, the image of the point (4, 2) is:
P'(x, y) = (4, 2) + (- 5, 2)
P'(x, y) = (- 1, 4)
The image of the point (4, 2) by using a translation formula is (- 1, 4).
