if sine Theta is less than 0 and tan Theta is greater than 0 then
Answer:
Sine Theta is a negative number, Tan Theta is a greater number then zero.
Step-by-step explanation:
If Sine Theta is less then zero, she is a negative number. So 0 - y = -y.
So if Tan Theta is a greater number than zero, her number is not negative. So 0 + y = y

Joe is asked to prove that the sum of the interior angles (, , and ) of the triangle he has drawn equals 180°. His triangle is represented in the diagram above, and his work is shown below.
The angles <1, <2, and <3 will not add up to 180 degrees. The angles <1 and <2 are alternate interior angles, and the angles <2 and <3 are also alternate interior angles, AB is parallel to CD.
What is angle sum property of triangle?The angle sum property of a triangle states that the sum of the interior angles of a triangle is always equal to 180 degrees. This means that if you measure the angles inside any triangle and add them up, the result will always be 180 degrees. This property holds true for all types of triangles, whether they are equilateral, isosceles, or scalene.
To understand this property, consider a triangle ABC with interior angles angle A, angle B, and angle C. If we draw a line segment from vertex A to a point D on side BC such that it is parallel to the side AB, then we can see that angle A and angle C are alternate interior angles of the parallel lines AB and CD. Similarly, angle B and angle C are alternate interior angles of the parallel lines BC and AD.

Select all the true statements
The true statements are;
1) AB + BC = AC
Length of BC = |6 - 1|
2) ∠JMK = 50°
∠KML = 35°
How to Interpret Number Line intervals?
1) From the given number line interval, we can deduce the interpretation as follows;
AB + BC = AC
Length of BC = 5 units or |6 - 1|
Length of B = 3 Units
2) We can see that ∠JML is an angle triangle. Thus, ∠JML = 85°. Thus;
6x + 2 + 4x + 3 = 85
10x + 5 = 85
10x = 85 - 5
10x = 80
x = 80/10
x = 8°
Thus;
∠JMK = 6(8) + 2
∠JMK = 50°
∠KML = 85° - 50°
∠KML = 35°

Using first principle method, find the derivative of x^6
The derivative of a function f(x) is defined as the limit,
\(f'(x):=\displaystyle\lim_{h\to0}\frac{f(x+h)-f(x)}h\)
With f(x) = x⁶, we have
\(f'(x)=\displaystyle\lim_{h\to0}\frac{(x+h)^6-x^6}h\)
Expand f(x + h) in the numerator:
(x + h)⁶ = x⁶ + 6x⁵h + 15x⁴h² + 20x³h³ + 15x²h⁴ + 6xh⁵ + h⁶
so that the x⁶ terms cancel, leaving us with
\(f'(x)=\displaystyle\lim_{h\to0}\frac{6x^5h+15x^4h^2+20x^3h^3+15x^2h^4+6xh^5+h^6}h\)
h is approaching 0, so h ≠ 0 and we can cancel the common factor in the numerator and denominator:
\(f'(x)=\displaystyle\lim_{h\to0}\left(6x^5+15x^4h+20x^3h^2+15x^2h^3+6xh^4+h^5\right)\)
Now as h converges to 0, each term containing h vanishes, leaving us with
f'(x) = 6x⁵

Which ordered pair makes both inequalities true?
y> -3x +3
y22x-2
O (1,0)
O (-1,1)
O (2,2)
O (0,3)
None of the ordered pairs (1, 0), (-1, 1), (2, 2), and (0, 3) make both inequalities true.
To determine which ordered pair makes both inequalities true, we can substitute the given values into the inequalities and check for validity:
1. (1, 0):
For y > -3x + 3: 0 > -3(1) + 3 -> 0 > 0, which is not true.
For y < 2x - 2: 0 < 2(1) - 2 -> 0 < 0, which is not true.
Therefore, (1, 0) does not satisfy both inequalities.
2. (-1, 1):
For y > -3x + 3: 1 > -3(-1) + 3 -> 1 > 6, which is not true.
For y < 2x - 2: 1 < 2(-1) - 2 -> 1 < -4, which is not true.
Therefore, (-1, 1) does not satisfy both inequalities.
3. (2, 2):
For y > -3x + 3: 2 > -3(2) + 3 -> 2 > -3, which is true.
For y < 2x - 2: 2 < 2(2) - 2 -> 2 < 2, which is not true.
Therefore, (2, 2) does not satisfy both inequalities.
4. (0, 3):
For y > -3x + 3: 3 > -3(0) + 3 -> 3 > 3, which is not true.
For y < 2x - 2: 3 < 2(0) - 2 -> 3 < -2, which is not true.
Therefore, (0, 3) does not satisfy both inequalities.
None of the given ordered pairs satisfy both inequalities simultaneously.

Option (O log 7) refers to the base-10 logarithm of 7, represented as log10(7), which is not the same as ln (7). Optional (O log, 10) and (O log, e) mathematical expressions are not acceptable.
what is logarithm?In mathematics, the logarithm is the reciprocal of a power. As a result, the exponent by which b must be raised to achieve a number x matches its logarithm in base b. For example, because 1000 = 103, the base-10 logarithm is 3, or log10 = 3. For example, the base 10 logarithm of 10 is 2, but the square of 10 is 100. Log 100 = 2. A logarithm (or log) is the mathematical word used to answer questions such as how many times a base of 10 must be multiplied by itself to get 1,000. The answer is 3 (1,000 = 10 10 10).
When you compute (In), you are calculating the natural logarithm of 7, which is indicated as ln(7) or loge (7).
As a result, the expression you'd be looking up the value of is: ln(7) or loge (7).

Step-by-step explanation:
1.Clare recorded the amounts of time spent doing homework, in hours per week, by students insixth, eighth, and tenth grades. She made a dot plot of the data for each grade and provided thefollowing summary.Students in sixth grade tend to spend less time on homework than students in eighth andtenth grades.The homework times for the tenth-grade students are more alike than the homework timesfor the eighth-grade students.no
Each point in the plot represents a student.
From the first statement we know that:
"Students in sixth grade tend to spend less time on homework than students in eighth and tenth grades."
We must look the three plots and see which one has more dots in the lower numbers of hours.
We can see that the plot B is the plot with more dots in the region of lower numbers of hours.
So from that we can say that the plot B correspond to the sixth grade.
Now we must read the next statement in order to know which plot correspond to the eighth and tenth grades.
The next statement tell us that:
"The homework times for the tenth-grade students are more alike than the homework times for the eighth-grade students."
So, the key is in: "the tenth-grade students are more alike", the meaning of that is that the points are more scattered or dispersed. If we compare the plot A and C, we see that the points in A are more scattered or dispersed than in the plot C. So, the plot A corresponds to the tenth grade, and the last one (plot C) to the eight grade.

(X-13)+x+(×/5+6)=180
Answer:
72 85 23
Step-by-step explanation:
Equation
(x - 13) + (x/5 + 6) + x = 180 Multiply the equation by 5
Solution
5(x - 13) + 5(x/5 + 6) + 5x = 180*5 Remove the brackets
5x - 65 + x + 30 + 5x = 900 Combine like terms on the left
11x - 35 = 900 Add 35 to both sides
35 35
11x = 935
x = 85
Answer
x - 13 = 85 - 13 = 72
x = 85
x/5 + 6 = 17 + 6 = 23
Total = 180
It might be easier not to multiply through by 5 at the beginning
(x - 13) + (x/5 + 6) + x = 180 Remove the brackets
x - 13 + x/5 + 6 + x = 180 Combine like terms
2x + x/5 -- 7 = 180
x/5 = .2x Put 0.2x in for x/5
2.2x - 7= 180 Add 7 to both sides
7 7
2.2x = 187 Divide by 2.2
x = 187/2.2
x = 85

What is the area of circle?The area of a circle is calculated using the formula A = πr², where "A" is the area of the circle.
We know,
Area of Rectangle = l × w, where l = length and w = width
Area of Circle = \(\pi r^{2}\), where r = radius.
find the area of the rectangle,
length = 6 in and width = 4 in
Area of Rectangle = 6 × 4 = 24 inch²
Here given the circle radius is 1 inch, and we use π as 3.14
Area of Circle = \(\pi r^{2}\)
Area of Circle = 3.14 × 1² = 3.14 in²
The area of the shaded region as per figure below is:
Area of the shaded region = Area of Rectangle - Area of Circle
Area of the shaded region = 24 - 3.14 = 20.86 in²
Therefore, the answer is D. 20.86 square inches.

a quadratic function with a constant difference of 2
an exponential function with growth factors of 1, then 2, then 4, ..
The best description of the graph is "a quadratic function with a constant difference of 2."
A quadratic function is a function of the form f(x) = ax^2 + bx + c, where a, b, and c are constants. In a quadratic function, the graph forms a parabola.
In the given graph, if the differences between consecutive points on the graph are constant and equal to 2, it indicates a constant difference in the y-values (vertical direction) as the x-values (horizontal direction) increase. This is a characteristic of a quadratic function.
On the other hand, an exponential function with a growth factor of 2 would result in a graph that increases at an increasing rate, where the y-values grow exponentially as the x-values increase. This is not observed in the given graph.
Therefore, based on the information provided, the graph best represents a quadratic function with a constant difference of 2.
