Look at this square. Find the value of
S.
S
Perimeter = 16 miles
S =
miles
The value of S, which represents the length of each side of the square, is 4 miles.
To find the value of S, we need to determine the length of each side of the square. Given that the perimeter of the square is 16 miles, we can use the formula for the perimeter of a square, which is 4 times the length of a side.
Perimeter = 4 × S
Given that the perimeter is 16 miles, we can substitute this value into the equation:
16 = 4 × S
To solve for S, we divide both sides of the equation by 4:
16 ÷ 4 = S
4 = S
Therefore, S, which stands for the square's side lengths, has a value of 4 miles.
So, S = 4 miles.
This means that each side of the square measures 4 miles, and the square has equal sides and right angles at each corner.

What is the domain and range of the following relation? Is it a function?{(1, 1), (2, 2), (3, 5), (4, 10), (5, 15)}
The given relation is a set of ordered pairs {(1, 1), (2, 2), (3, 5), (4, 10), (5, 15)}. The first element of each pair represents the input or domain value, and the second element represents the output or range value.
The domain of the relation is the set of all first elements of the ordered pairs, which is {1, 2, 3, 4, 5}. The range of the relation is the set of all second elements of the ordered pairs, which is {1, 2, 5, 10, 15}.
To check whether the relation is a function or not, we need to ensure that each input value (i.e., element of the domain) is associated with a unique output value (i.e., element of the range). In other words, there should not be more than one ordered pair with the same first element.
In this case, each input value is associated with a unique output value, so the relation is indeed a function. Specifically, it is a function from the set of integers {1, 2, 3, 4, 5} to the set of integers {1, 2, 5, 10, 15}.

What is in slope-intercept form?
Given the slope of the line and the intercept it forms with the y-axis, one of the mathematical forms used to derive the equation of a straight line is called the slope intercept form. Y = mx + b, where m is the slope of the straight line and b is the y-intercept, is the slope intercept form.f(x) = 2x+5
y = 2x + 5
x = 2y + 5
x - 5 = 2y
x - 5/2 = y
\(f^{-1} (x) = \frac{x - 5}{2}\)
the final equation in slope- intercept form.
So, \(f^{-1} (x) = \frac{1}{2} x - \frac{5}{2}\)

How many solutions y=5x-4 y=5x-5
Answer:
No solution
Step-by-step explanation:
Any equations with the same slope are parallel, or will never intersect.
In a slope-intercept equation, this would mean the 'm' values are the same.
y = mx + b
Two equations:
y = 5x - 4
y = 5x - 5
Since the two equations given have the same slope, they will never intercept and therefore have no solution.

What is Trig Identities?Trig identities come in handy when we need to express one trig function in terms of another. The most famous trig identity is derived straight from the Pythagorean Theorem:
sin² t + cos² t = 1
According to the given data:For an angle t in Quadrant IV, we know sin t is positive.
From the trig identity sin² t + cos² t = 1
we can also write as:
sin t + cos t:
Now,
sin² t + cos² t = 1
sin² t = 1 - cos² t
sin t = ±√( 1 - cos² t)
As noted above,
sin t is positive for t in the Quadrant IV, and so we have
sin t = √( 1 - cos² t)

The height of the can is 4.96 cm
The formula for surface area of a cylinder is,
SA = 2B + Ph
where B represents the area of one base.
P is the perimeter of the base
and h is the height of the cylinder
Here, the diameter of the can is 6 cm
so, the radius r would be 6/2 = 3 cm
The base of the can is circular.
Using the formula for the area of circle the base area would be,
B = π × r²
B = π × 3²
B = 28.27 sq. cm.
And the perimeter of the circular base is nothing but the circumference of circle.
P = 2πr
P = 2π(3)
P = 6π
P = 18.85 cm
Here, SA = 150 sq.cm.
Substituting values in above formula,
SA = 2B + Ph
150 = 2(28.27) + (18.85)h
h = (150 - 56.54) / (18.85)

suppose that you and a friend are playing cards and decide to make a bet. if your friend draws two non-face cards, where a face card is a jack, a queen, or a king, in succession from a standard deck of 52 cards replacing the first card, you give him $30. otherwise, he pays you $50. if the same bet was made 20 times, how much would you expect to win or lose? round your answer to the nearest cent, if necessary.
I will win about $ 59.
This is a question of permutations and combinations.
We know that,
Probability of getting two non face cards = \(\frac{^{40}C_2}{{^{52}C_2}}\) = 10/17
Probability of not getting two non face cards = 1 - (10/17) = 7/17
Hence, we can write,
Money I will get = (7/17)*50*20 = $ 411.764
Money I'll have to pay = (10/17)*30*20 = $ 352.94
We know that,
Money left with me = Money I will get - Money I'll have to pay

Exercise. A curve C is described by the vector-valued function (t) (1+ 2t, 3- 4t,67t) Exercise. Find a vector parallel to the curve when t-1: -4 7 Exercise. Find all t-values where l and e' are orthogonal. t1/2, 3/4,-6/7 Previous
A vector parallel to the curve described by the vector-valued function (t) when t = -4 is (-7, -11, -268). The t-values where l and e' are orthogonal are t = 1/2, t = 3/4, and t = -6/7.
The vector-valued function (t) = (1 + 2t, 3 - 4t, 67t) describes the curve C. To find a vector parallel to the curve when t = -4, we substitute t = -4 into the function and calculate the resulting vector. Plugging in t = -4, we get (-7, -11, -268), which represents a vector parallel to the curve at that particular point.
Next, we need to find the t-values where l and e' (two vectors) are orthogonal. Two vectors are orthogonal when their dot product is zero. Given the values t = 1/2, t = 3/4, and t = -6/7, we substitute these values into the vectors l and e' and calculate their dot product. If the dot product equals zero, it indicates orthogonality. Therefore, t = 1/2, t = 3/4, and t = -6/7 are the t-values where l and e' are orthogonal.
