find the slope of the line that goes through (3, 7) and (-1, 4)
The slope of the line that goes through the points (3, 7) and (-1, 4) is 3/4.
The slope formula is: m = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are two points on the line. This will allow us to determine the slope of the line that passes through the points (3, 7) and (-1, 4).
When we enter the provided coordinates into the formula, we get:
m = (4 - 7) / (-1 - 3) = -3 / (-4) = 3/4
The pace at which the y-coordinates vary in relation to the x-coordinates is shown by the slope, which expresses how steep the line is. In this instance, the slope of 3/4 means that the y-coordinate increases by 3 units for every 4 units that the x-coordinate increases. Likewise, the y-coordinate falls by 3 units for every 4 units decrease in the x-coordinate.

Answer:
The slope of the line that goes through (3,7) and (-1,4) is 3/4
Step-by-step explanation:
Apply the formula m = (y₂ - y₁) / (x₂ - x₁) to find the slope.
(x₁, y₁) = (3, 7)
(x₂, y₂) = (-1,4)
= (4 - 7) / ((-1) - 3)
= -3 / -4
Since both of them are negative, they cancel out to 3/4.

Information is given about a polynomial f(x) whose coefficients are real numbers. Find the remaining zeros of f. Degree 4: zeros: O 3-5i, 4i
O 3+5i, 4-i O -3-5i,-4
We have all the zeros of the polynomial. Therefore, there are no remaining zeros of f(x). The given polynomial f(x) is a degree 4 polynomial. The given zeros of f(x) are `3-5i`, `4i`, `3+5i` and `4-i`.
We have to find the remaining zeros of f.
The remaining zeros of f are the solutions of f(x) = 0 which are not given in the question. Degree of polynomial = 4
We are given all the four zeros of the given polynomial.
So, we can write the expression for f(x) by using all these zeros.
f(x) = a(x - 3 + 5i)(x - 3 - 5i)(x - 4i)(x - 4 + i) [Using the zero factor property]
Now, we have to find the remaining zeros.
Let's find it out :f(x) = a(x - 3 + 5i)(x - 3 - 5i)(x - 4i)(x - 4 + i)f(x)
= a[(x - 3)² - (5i)²][(x - 4)² - (i)²]
(Using a² - b² = (a + b)(a - b))f(x)
= a[(x - 3)² + 25][(x - 4)² + 1] (Since i² = -1)f(x)
= a(x² - 6x + 34)(x² - 8x + 17)f(x)
= a[x⁴ - 14x² + 33x + 612] (Expanding the above expression)
The polynomial f(x) is a degree 4 polynomial.
Hence, we have all the zeros of the polynomial. Therefore, there are no remaining zeros of f(x).

which of the following is a true statement?select one:interval is the name of a particular octave sizeoctave is the name of a particular interval sizethe fifth is a kind of octavea synonym for distance is octave
The true statement is: "Octave is the name of a particular interval size."
In music theory, an octave refers to the interval between two pitches where the higher pitch has a frequency that is exactly twice that of the lower pitch. It represents a doubling or halving of the frequency. For example, if we start on the note A and move up to the next A, we have traversed an octave.
An interval, on the other hand, refers to the distance between two pitches. It is the numerical representation of the difference in pitch between two notes.
The statement mentioning "interval as the name of a particular octave size" is incorrect because the octave is a specific interval size, not the other way around.
The statement suggesting that "the fifth is a kind of octave" is also incorrect. The fifth is a specific interval that represents the distance of five diatonic scale steps between two pitches.
Lastly, the statement that "a synonym for distance is octave" is not true. While an octave represents a specific interval size, the term "distance" is a more general term that can refer to the measurement between any two pitches, regardless of the specific interval size.

The cross section of a parabolic reflector has a vertical axis of symmetry with its vertex at (0,0). The focus of the reflector is 6 feet above the vertex. The reflector extends 5.5 feet to either side of the vertex. What is the depth of the reflector? Round your answer to the nearest hundredth.
The depth of the reflector is about _____
feet.
Answer:
1.26 feets
Step-by-step explanation:
Given the following :
Vertex (0, 0)
Focus of reflector = 6 feets
Extension = 5.5 feets
Equation to obtain conic section of a parabola:
(x - h)² = 4p(y - k)
Vertex (0, 0)
h =0 ; k = 0, p = 6, x = 5.5
(5.5 - 0)² = 4*6(y - 0)
30.25 - 0 = 24(y - 0)
30.25 = 24y
y = 30.25 / 24
y = 1.26
Hence, depth of reflector = 1.26 feets
3- Find the Domain (ONLY) for each of the following functions (60 points - 10 each) a) f(x) = x²-3x − 4 b) f(x) 2 x-3 c) M(x) √x-5 2 10 d) g(x) = e) h(x) a) f(x) = 4, x +9 x-4 drhring 16 miles since a full tank 2x-5 x-2x-15
The domain of each function is determined by the values of x for which the function is defined. The domain of function a) f(x) = x²-3x-4 is all real numbers. The domain of function b) f(x) = 2x-3 is all real numbers. The domain of function c) M(x) = √(x-5) is x ≥ 5. The domain of function d) g(x) = (x+9)/(x-4) is x ≠ 4. The domain of function e) h(x) = 16/(2x-5) is x ≠ 2.
a) The function f(x) = x²-3x-4 is a polynomials function, and polynomial functions are defined for all real numbers. Therefore, the domain of f(x) is all real numbers.
b) The function f(x) = 2x-3 is a linear function, and linear functions are defined for all real numbers. Hence, the domain of f(x) is all real numbers.
c) The function M(x) = √(x-5) represents a square-root function. Square root functions are defined only for non-negative values inside the square root. In this case, x-5 must be greater than or equal to zero, which implies x ≥ 5. Therefore, the domain of M(x) is x ≥ 5.
d) The function g(x) = (x+9)/(x-4) is a rational function. Rational functions are defined for all real numbers except the values that make the denominator equal to zero. In this case, the denominator is x-4, so the function is undefined when x = 4. Hence, the domain of g(x) is x ≠ 4.
e) The function h(x) = 16/(2x-5) is also a rational function. Similar to the previous explanation, rational functions are defined for all real numbers except the values that make the denominator equal to zero. In this case, the denominator is 2x-5, so the function is undefined when x = 5/2. Therefore, the domain of h(x) is x ≠ 5/2 or x ≠ 2.

Apply Axiom 2 to find the unique fold (line) that places p1 = (1,4) on to p2 = (3,1).
Check your answer by plotting the two points in Desmos, plot also the fold line. You could even
print this out and make sure it works. (With only one fold the result is just a folded piece of paper,
not an origami crane or even a hat, but check that the two points are placed on top of each othe
We are asked to apply Axiom 2, also known as the "unique fold" axiom, to find the line that maps point p1 = (1,4) onto point p2 = (3,1). We will use the formula for the equation of a line to determine the equation of the line that satisfies this condition. We can then verify our answer by plotting the two points on a graphing tool like Desmos.
Axiom 2 states that for any two distinct points p1 = (x1, y1) and p2 = (x2, y2), there exists a unique line that maps p1 onto p2. The equation of a line passing through two points can be found using the point-slope formula:
y - y1 = m(x - x1)
where m is the slope of the line. To find the slope, we use the formula:
m = (y2 - y1) / (x2 - x1)
In this case, p1 = (1,4) and p2 = (3,1), so we can substitute these values into the formulas to find the equation of the line. The slope is:
m = (1 - 4) / (3 - 1) = -3 / 2
Using the point-slope formula with p1, we have:
y - 4 = (-3/2)(x - 1)
Simplifying the equation, we get:
y - 4 = (-3/2)x + 3/2
y = (-3/2)x + 11/2
This is the equation of the unique line that maps p1 onto p2. To verify our answer, we can plot the two points (1,4) and (3,1) on a graphing tool like Desmos and observe that they lie on the same line with the equation
y = (-3/2)x + 11/2.

The probability that a randomly selected college student will find a parking spot in the library parking lot in less than 3 minutes is found as `0.7475`. Hence, the option D is correct.
The length of time it takes a college student to find a parking spot in the library parking lot follows a normal distribution with a mean of 2.5 minutes and a standard deviation of 0.75 minute.
We are supposed to find the probability that a randomly selected college student will find a parking spot in the library parking lot in less than 3 minutes.
So, we need to find `P(x < 3)` where `x` is the time taken to find a parking spot in the library parking lot.
Now, z-score will be
`z = (3 - 2.5)/0.75
= 0.67`
By looking at the z-score table, the probability that corresponds to z = 0.67 is 0.2514.
Therefore,
`P(x < 3) = P(z < 0.67)
= 0.2514 + 0.5
= 0.7514
≈ 0.7475 (approx)`
So, the correct option is `0.7475`. Hence, the answer is option D.

The equation for the line in slope-intercept form is: y = (-2/9)x + 41/9 This is the required equation for the line that passes through the points: (-2, 5) and (7, 3) in point-slope form.
The equation for the line that passes through the points: (-2,5) and (7,3) in point-slope form can be found as follows:
Solution:
Given points are (-2, 5) and (7, 3).
Let (x1, y1) = (-2, 5)and (x2, y2) = (7, 3)
Formula used: Point-slope form of a line: y - y1 = m(x - x1)
Slope of the line: m = (y2 - y1) / (x2 - x1)
Substitute x1, y1, x2, and y2 in the slope formula: Slope m = (3 - 5) / (7 - (-2)) = -2 / 9
Slope-intercept form of the line: y = mx + b
Substitute slope m, and any one point (x1, y1) in the slope-intercept formula: 5 = (-2/9) * (-2) + b
Simplify and solve for b: 5 = 4/9 + b b = 41/9
The equation for the line in slope-intercept form is: y = (-2/9)x + 41/9

m < PCA = m < CAD ( alternate angles)
m < BAD = m <CAD ( given)
Also m < CAB = m < PCA + m < CPA ( exterior angle of a triangle theorem).
Also m < CAB = m< CAD + m < BAD (given)
So m < PCA + m < CPA = m < CAD + m < BAD
But m < PCA = m < CAD
so m < CAD + m < CPA = m < CAD + m BAD
So m < CPA = m < BAD
But m < PCA = m < CAD = m BAD
therefore m < CPA = m < PCA
That makes triangle CAP isosceles
Therefore AP = AC.
