Answer:
Anne will walk for 2 hours.
Step-by-step explanation:
Distance formula = velocity × time
Total distance is 18.5 km
Anne travels by train = 10 km
and by bus = 1.5 km
let the distance covered by anne by walking be x
10 + 1.5 + x = 18.5
x = 18.5 - 10 - 1.5
x = 7km
Rate of walking is 3.5 km per hour
the time she will take while walking = 7 ÷ 3.5 = 2 hours.

Domain: [tex]\boldsymbol{(-\infty, \infty)}[/tex]
Range: [tex]\boldsymbol{(-\infty, \infty)}[/tex]
=======================================================
Explanation:
domain = set of all possible x inputs
range = set of all possible y outputs
--------------
In this case, the domain is the set of all real numbers because the graph stretches forever to the left and right. There aren't any gaps, holes, jumps, etc to worry about. Any real number works as an input.
We can say x is between [tex]-\infty[/tex] and [tex]\infty[/tex] and write [tex]-\infty < x < \infty[/tex]
That turns into the interval notation [tex](-\infty, \infty)[/tex]
The curved parenthesis are always used with either infinity because we cannot reach them.
--------------
The range is the same story, but with the y values this time. The graph stretches forever upward and downward due to the arrow.
If it peaked at y = 4, then the range would be [tex](-\infty, 4][/tex], but instead the graph goes beyond y = 4 because of that upward arrow.

Which statement is true regarding the graphed functions?
Answer:
4th option
Step-by-step explanation:
the solution is at the point of intersection of the 2 lines, that is
(- 2, 4 ) where x = - 2 , then
f(- 2) = g(- 2)
Answer: D. or f(–2) = g(–2)
Step-by-step explanation:
In the given graph, the two lines intersects at x = -2
And intersection point is that point, where the y values of the two graphs are equal.
That is: f(x) = g(x)
And at x=-2, the y values are equal. So:

Tau decides to save money in the following ways:
He saves $ 1 in the first week $1.20 in the second week, $1.40 in the third week, and so on.
1) How much would he save in the nth week?
Answer:
1.00 + [(n - 1) × 0.20]
or
0.80 + [n × 0.20]
Step-by-step explanation:
week 1: 1.00
week 2: 1.20
week 3: 1.40
we could rewrite this as:
week 1: 1.00 + [0 × 0.20]
week 2: 1.00 + [1 × 0.20]
week 3: 1.00 + [2 × 0.20]
we can write this overall as:
week __ : 1.00 + [x × 0.20]
> x being the amount of weeks that have passed since week 1
but, we need to express this as in terms of nth, so, we need to figure out how the week is related to the x value
each week, we subtract 1 from the week number [to account for week 1]
so, we can write this as: 1.00 + [(n - 1) × 0.20]
or, we can backtrack from the first week, and start our counting at 0.80:
0.80 + [n × 0.20]
we can test this out:
(week 1)
1.00 + [(n - 1) × 0.20]
1.00 + [(1 - 1) × 0.20]
1.00 + [0 × 0.20]
1.00
or...
(week 1)
0.80 + [n × 0.20]
0.80 + [1 × 0.20]
0.80 + 0.20
= 1.00
So, nth week should be expressed as either:
1.00 + [(n - 1) × 0.20] or
0.80 + [n × 0.20]
(the second one is a little bit more simplified, but it depends on how you're supposed to write it)

What is the greatest area of a rectangle with a perimeter of 60cm? What is the length and width of this rectangle?
The length and width of this rectangle are 15 cm respectively
How to determine the greatest area?The perimeter is given as:
Perimeter, P = 60
The greatest area is calculated as:
Greatest = (P/4)^2
Substitute 60 for P
Greatest = (60/4)^2
Evaluate the quotient
Greatest = 15^2
Evaluate the exponent
Greatest = 225 square centimeters
Hence, the greatest area is 225 square centimeters
How to determine the length and widthWe understand that the area is the greatest.
In such a scenario;
Length = Width
This means that:
Area =Length^2 =Width^2
So, we have:
Length^2 =Width^2 = 225
Take the square root
Length =Width = 15
Hence, the length and width of this rectangle are 15 cm respectively

Given circle D, calculate the measure of arc AC if AD=16 and BD=13.
Answer:
18.66
Step-by-step explanation:
Using the pythagorean theorem:
a^2 + b^2 = c^2
a^2 + 13^2 = 16^2
a^2 + 169 = 256
a^2 = 87
a = 9.33
Since we need to figure out length AC and not just AB, we can multiply our answer by 2:
9.33 x 2 = 18.66
Answer:
71.32°
Step-by-step explanation:
The measure of angle ADB can be found using the trig relation ...
Cos = Adjacent/Hypotenuse
__
cos(ADB) = DB/AD = 13/16
Using the inverse function, ...
∠ADB = arccos(13/16) ≈ 35.659°
Arc AC has the same measure as angle ADC, which is double the measure of angle ADB.
Arc AC = 2×35.659° = 71.318° ≈ 71.32°
The measure of arc AC is about 71.32°.
_____
Additional comment
The length of arc AC is the product of the radius and its radian measure:
length AC = (16)(71.32π/180) ≈ 19.92 . . . units

Answer:
The triangle will translate along the arrow and reach the head of the arrow.
Step-by-step explanation:
Translation is a category of motion in which one body moves along towards a particular direction and reaches a particular point.
In translation, the rotational motion is not present. Also, the translational motion is a one dimensional motion.
In the given figure, the triangle is present at the tail of the arrow.
The arrow depicts the direction of the translational motion.

How are rays and angles related? a ray , and an angle is two . the measure of an angle related to the length of its sides. so, the measure of an angle the same at all distances from its vertex.
A ray is a part of a line that starts at a point (called the endpoint) and extends infinitely in one direction. An angle is formed when two rays share a common endpoint (vertex).
A ray has one endpoint: A ray is a one-dimensional figure that starts at a single point (the endpoint) and extends infinitely in one direction. On the other hand, an angle is formed by two rays, each with its own endpoint, meeting at a common vertex.
An angle is two rays: As mentioned earlier, an angle is created when two rays share a common endpoint. The two rays are referred to as the sides of the angle, and the endpoint they share is called the vertex.
The measure of an angle is determined by the amount of rotation: The measure of an angle is not dependent on the lengths of its sides but rather on the amount of rotation between its two rays. To measure an angle, we compare it to a standard unit of angle measurement, usually degrees. One full rotation (360 degrees) corresponds to a complete circle, and angles are measured based on the fraction of a full circle they represent.
The measure of an angle remains the same at all distances from its vertex: The measure of an angle is independent of the length of its sides or how far away an observer is from the vertex. For example, a 60-degree angle remains a 60-degree angle whether you look at it from up close or from a distance. This is because the measure of an angle depends only on the relative positions of its two rays, not on the size of the shape it forms.
