(tan 0) (x) = 1 where x is atrigonometric function.Which of the following functionssubstituted for x solves the above equation?
ANSWER :
d. cot θ
EXPLANATION :
Note that the reciprocal of tangent is cotangent.
[tex]\frac{1}{\tan\theta}=\cot\theta[/tex]If reciprocals are multiplied with each other, the result is 1.
From the problem, we have :
[tex](\tan\theta)(x)=1_[/tex]Since the result of the product is 1, the tangent function must be multiplied by its reciprocal.
That will be cotangent.
Or we can just simply divide the equation by tan θ.
[tex]\frac{\cancel{\tan\theta}(x)}{\cancel{\tan\theta}}=\frac{1}{\tan\theta}=\cot\theta[/tex]Write an equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation.
(-5,-5) x= -4x+1
y = -5x -25 is the equation in slope-intercept form of the line that passes through the given point (-5,-5) and is parallel to the given equation y = -4x+1.
The standard form of an equation of a line in slope-intercept form is
y = mx + c
where m represents the slope of the line and c represents the y intercept.
The equation of the parallel line is
y = -4x + 1
Here the slope of the line is -4 and the intercept is +1.
Two line that are parallel to each other have same slope.
So, the slope of the line passing through the point(-5, -5) and is parallel to the line y = -4x + 1 is -4.
putting the point given in the standard form
y = m(x) + c
-5 = -4(-5) + c
-5 = 20 + c
c = -25
The equation of line is y = -5x -25
Therefore, y = -5x -25 is the equation in slope-intercept form of the line that passes through the given point (-5,-5) and is parallel to the given equation y = -4x+1.

1st term + common difference (desired term - 1)
□+[ ] [ ] - 1)
A. -4
B. +4
C. 205
D. -48
The 205th term of the sequence is 768 with a common difference of 4.
What is the common difference?In an arithmetic series, a common difference is one between any term and its predecessor, and it is typically denoted by the letter "d."To find the common difference in an arithmetic sequence, subtract the first term from the second term, the second term from the third term, and so on.The difference that exists between every pair of phrases that follow one another in a series is a common difference.For example, the number 3 is a frequent difference in the series 4, 7, 10, 13, and so on. A series of differences constitute an arithmetic progression.The common difference is so named because it is both the difference between each number in the sequence and the same, or common, to all of them.So, the sequence is:
-48, -44, -40, -36, -32,... +4
The common difference is: -48 + 4 = - 44 ⇒ 4
Formula: aₙ = a + (n - 1)d
Now calculate as follows:
aₙ = a + (n - 1)d
aₙ = -48 + (205 - 1)4
aₙ = -48 + (204)4
aₙ = -48 + 816
aₙ = 768
Therefore, the 205th term of the sequence is 768 with a common difference of 4.

The rate of change of the area is -80.5 [tex]inches^{2}[/tex]/sec.
Given:
A right triangle has legs of 21 inches and 28 inches whose sides are changing.The short leg is decreasing by 2 in/sec and the long leg is shrinking at 5 in/sec.
Let's set the two legs as a and b, so the lengths are:
a = 21 - 2t
b = 28 - 5t
The area is:
area a = ab /2
= (21 - 2t) (28 - 5t)/2
= (588 - 105t - 56t + 10[tex]t^{2}[/tex]/2
a = 5[tex]t^{2}[/tex] - 161t/2 - 299
The rate of change of the area is:
da/dt = d(5[tex]t^{2}[/tex] - 161t/2 - 299)/dt
da/dt = 10t -161/2
And at t=0,

WILL GIVE BRAINLIEST!!!!
The slope and y-intercept of 2y = 6x - 12 are 3 and (-6) respectively.
What is the slope intercept form of a line?
The line with m as the slope, and c as the y-intercept is the graph of the linear equation y = mx + c. The values of m and c are real integers in the slope-intercept form of the linear equation.
The slope, m, is a measure of how steep a line is. Sometimes, the gradient of a line is referred to as its slope. A line's y-intercept, c, denotes the y-coordinate of the location where the line's graph crosses the y-axis.
Given, the equation of the line is 2y = 6x - 12
Dividing the given equation by 2 we get, y = 3x - 6 ⇒ y = 3x + (-6)
Comparing the equation with the standard form of slope intercept form of a line as established in literature, we have:
Slope = m = 3 and y-intercept = c = -6
Thus, the slope and y-intercept of 2y = 6x - 12 are 3 and (-6) respectively.

find the gradient of lines a and b
Answer:
Line A: 4
Line B: -2
Step-by-step explanation:
Note: gradient means slope, or m, in this context
To find the slope of a line, use the formula:
[tex]m = \dfrac{\Delta y}{\Delta x} = \dfrac{y_2-y_1}{x_2-x_1}[/tex] where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points on the line
Line A has points (2, 2) and (3, 6). To find the slope of the line, simply plug these values into the formula for m :
[tex]m_{\mathrm{line \, A}}=\dfrac{6-2}{3-2}=\dfrac{4}{1}=4[/tex]
So, the slope, or gradient, of line A is 4.
Next, do the same thing for Line B.
Find two points on the line:
(0, 8) and (1, 6)
And plug these values into the formula:
[tex]m_{\mathrm{line \, B}}=\dfrac{6-8}{1-0}=\dfrac{-2}{1}=-2[/tex]
So, the slope, or gradient, of line B is -2.

Give your answer in centimetres.
Lower bound =
Upper bound =
The lower bound for the length of the remaining ribbon is 13.8 cm, and the upper bound is 15.8 cm.
Here,
To work out the lower and upper bounds for the length of the remaining ribbon, we need to consider the possible scenarios that would result in the smallest and largest remaining lengths.
Given:
Original length of ribbon = 23 cm (correct to the nearest cm)
Length of the piece cut off = 87 mm (correct to the nearest mm)
First, let's convert the length of the piece cut off to centimeters:
1 cm = 10 mm
So, 87 mm = 87 / 10 cm = 8.7 cm (correct to the nearest mm)
Now, let's calculate the upper bound for the remaining ribbon length:
Upper bound = Original length - Length cut off + Tolerance
Upper bound = 23 cm - 8.7 cm + 0.5 cm (maximum possible rounding error for 87 mm)
Upper bound = 23 cm - 8.7 cm + 0.5 cm = 15.8 cm
Next, let's calculate the lower bound for the remaining ribbon length:
Lower bound = Original length - Length cut off - Tolerance
Lower bound = 23 cm - 8.7 cm - 0.5 cm (maximum possible rounding error for 87 mm)
Lower bound = 23 cm - 8.7 cm - 0.5 cm = 13.8 cm
So, the lower bound for the length of the remaining ribbon is 13.8 cm, and the upper bound is 15.8 cm.
