y = (4/5)x - 1 is the equation of the line in slope-intercept form

The equation of a line in slope-intercept form is y = mx + c.

Where m is the slope and c is the y-intercept (0, y)

slope = (y2-y1)/(x2-x1)

where (x1, y1) and (x2, y2) are the coordinates of two points that lie on the line

From the graph:

c = -1

x1 = 0, y1 = -1 and x2 = 5, y2 = 3

slope (m) = (3-(-1)) / (5-0) = 4/5

substitute m = 4/5 and c = -1 into y = mx + c:

y = (4/5)x - 1

Thus, the equation of the line in slope-intercept form is y = (4/5)x - 1

The area of a page of the book, "flowers of the four seasons". would be = 5.6× 10^-⁷ m²

To calculate the area of a book, the length and weight of the book must be determined which is then multiplied to give it's area in square metres or mm².

The number of pages that makes up the book, "flowers of the four seasons". = 22 pages.

Since the book has a square shape, the length and width is the same = 0.75 mm

To convert 0.75 mm to meter, divide by 1000= 0.00075m

The area of a page = Length× width = 0.00075×0.00075

The slope - intercept equation of a line that would pass through (1,-2) and has an undefined slope, is y = -2 x

The slope - intercept equation takes the form:

y = mx + b

m = slope

b = y - intercept

When the slope is undefined, it means that there is no y - intercept as the slope is a vertical line which crosses the x - axis alone. The slope would therefore be :

Distance of a fallen object is 25 feet.

Velocity is the pace and direction of an item's movement, whereas speed is the time rate at which an object is travelling along a route.

Given:

The formula for the speed of a falling object is v= √64d,

where v is the speed of the object in feet per second and d is the distance the object has fallen, in feet.

And also given that v = 200 feet per second.

Substituting the value to the formula,

200 = √64d

d = 200 / √64

d = 200 / 8

The equation of the new function, if we vertically compress the absolute value parent function, f(x) = |x| by a factor of 3: y = 1/x |x|

In this question we have been given an absolute value function f(x) = |x|

We need to find the equation of the function, if we vertically compress the absolute value parent function, f(x) = |x| by a factor of 3.

We know in function transformtaion there are two types of dilations.

1) Horizontal Dilation: a function y = f(x) into the form y = f(kx)

2) Vertical Dilation: a function y = f(x) into the form y = k f(x)

In both the cases, if k > 1, then the graph stretches and if 0 < k < 1, then the graph shrinks.

Since we vertically compress the absolute value parent function f(x) = |x| by a factor of 3, a scaling factor k must be 0 < k < 1

So, k = 1/3

And the required function wuld be, y = 1/3 * f(x)

y = 1/3 |x|

The absolute value parent function is f(x)= x. When we vertically compress the absolute value parent function f(x)= x by a factor of 3, the new equation is f(x)=⅓x.

The vertical compression by a factor of 3 means that the original graph will be compressed to a vertically scaled-down version of the original graph. This means that the graph will be shorter by a factor of 3.

To calculate the new equation, we must first determine the value of the constant “a”. The equation of the original absolute value parent function is f(x)=x. When we vertically compress the absolute value parent function f(x)=x by a factor of 3, the new equation is f(x)=ax. The value of “a” is equal to ⅓. Therefore, the new equation of the absolute value parent function f(x)=x when it is vertically compressed by a factor of 3 is f(x)=⅓x.

The graph of the new equation is shown below. The graph is shorter than the original absolute value parent function by a factor of 3.

From the graph, we can also see that the new equation has a minimum value of -1/3, a maximum value of 1/3, and the graph is symmetrical along the y-axis.

From the question, we have the following parameters that can be used in our computation:

y = ax - b

The above equation is a linear equation

To make the variable x the subject of the formula, we start by adding the variable b to both sides of the equation

Using the above as a guide, we have the following:

y + b = ax - b + b

Evaluate the like terms

This gives

y + b = ax

Next, we divide both sides of the equation by a

The ratio of two values, x - 3 to x + 5, is the definition of the function f(x) = (x - 3)/(x + 5). The denominator (x + 5) of this function is defined for any values of x such that it is not equal to 0. The fraction would be undefined if the denominator was set to 0, which indicates that the function is not defined for that particular value of x.

 For instance, the fraction would be undefinable if x = -5 because the denominator (x + 5) would be equal to 0. As a result, when x = -5, the function is not defined. The sole limitation on the function's domain is this one.

  The domain of the function accepts all other values of x. The function is defined, for instance, for x = -4, -3, -2, and so forth.

 In conclusion, x cannot be equal to -5, which is the only restriction on the domain of the function f(x) = (x - 3)/(x + 5). The domain of the function accepts all other values of x.

The number of comparisons required for an array of length 512 is

1+log2(512)=1+9=10.

Binary search:

Searching is an operation done to find the required element (or key) among a group of elements (an array).

Binary search or logarithmic search is a type of searching algorithm that can be used on a sorted array.

In this algorithm, we always check the middle number and compare the key with it. If the key equals the middle number, we're done. If the key is greater than the middle number, we know the key (if it's in the array at all) must be in the right half of the array. Conversely, if the key is less than the middle number, we know the key (if it's in the array at all) must be in the left half of the array. In other words, at every step of the search, we cut the array we're searching through in half. Of course, this only works because the array we started with is sorted.

In a binary search, at every step we compare the key with the middlemost value. If the key is greater than the middlemost value, we discard the left half of the data. If the key is less than the middlemost value, we discard the right half of the data. This process is repeated until we find the element we are looking for.

If we start with an array of length 2=21

, the worst-case scenario is we have to compare the key with both elements: 2 comparisons.

If we start with an array of length

4=22, the worst-case scenario is the key is not the middlemost element, we reduce our search to a 2-element array, and then we're in the worst-case scenario of the previous case: 1+2=3 comparisons.

If we start with an array of length

8=23

, the worst-case scenario is the key is not the middlemost element, we reduce our search to a 4-element array, and then we're in the worst-case scenario of the previous case: 1+3=4 comparisons.

Do you see a pattern? If we start with an array of length

2k, the worst-case scenario is we make 1+k

comparisons. Since 512=2log2(512)=29

The number of comparisons required for an array of length 512 is

1+log2(512)=1+9=10.

In general, the number of comparisons required for an array of length

n is 1+log2(n)

. We usually just round this to

log2(n). Remember that

log2(n)

is basically the number of times n can be cut in half until we get down to 1 or less, so this makes sense.

The measure of the length of side v is 228.8 inches

From the question, we have the following parameters that can be used in our computation:

A triangle

The readings from the triangle are given as

Angle U = 82 degrees

Angle W = 79 degrees

Side w = 690 inches

Start by calculating the measure of angle V using the following equation

Angle V = 180 - Angle U - Angle W

Substitute the known values in the above equation, so, we have the following representation

Angle V = 180 - 82 - 79

Evaluate the difference

Angle V = 19

The length of V is then calculated by making use of the following sine law

v/sin(V) = w/sin(W)

Substitute the known values in the above equation, so, we have the following representation

v/sin(19) = 690/ sin(79)

This gives

v =/sin(19) * 690/ sin(79)

Evaluate the expression

v = 228.8

Hence, the length is 228.8 inches
