Amelia stars reading at 3: 25 and reads for 15 minute. What type of angle is formed by the hour and minute hands of the clock wen Amelia fineshes reading
Answers
Answer:
Step-by-step explanation:
If sh starts reading at 3:25 and reads for 15 minutes, she is finished at 3:40. The hour hand is on the 3 and the minute hand is on the 8, so there is a difference of 25 minutes between the hour hand and the minute hand. Each 5-minute increment is 30 degrees (360 / 12) so 30 x 5 = 150 degrees. This is an obtuse angle. Not sure what kind of an answer you're looking for so I gave both the degree measure of the angle formed by the hour hand and the minute hand, and the classification of the angle.
Answer:
90 degrees, which is a right angle
Step-by-step explanation:
The time indicates when she starts reading is irrelevant. The only thing to notice is that she reeds for 15 minutes. Whenever you read for 15 minutes the angle that is formed by the hour and minute hands of the clock will always be the same, regardless of the starting time!
60 minutes comes down to 360 degrees.
1 minute = 60/60 and that comes down to 360/60 = 6 degrees.
15 minutes = 15 times 1 minute....
15 minutes comes down to 15* 6 = 90 degrees
90 degrees is a right angle

What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b or [tex]\dfrac{a}{b}[/tex]
We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).
Suppose that we've got a = 6, and b= 4, then:
[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]
Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.
Let we suppose that:
The radius of circle A = C unitsThe radius of circle B = s units.Then we get:
Circumference of circle A = [tex]2\pi r \: \rm units[/tex]Circumference of circle B = [tex]2\pi s \: \rm units[/tex]As per the given information:
The circumference of a circle B is 80% of the circumference of circle A, or:
[tex]2\pi s \: \rm units[/tex] = 80% of [tex]2\pi r \: \rm units[/tex]
or:
[tex]2\pi s = \dfrac{2\pi r}{100} \times 80\\\\s = 0.8r \: \rm units[/tex]
Also, we have:
Area of circle A = [tex]\pi r^2 \: \rm units[/tex]Area of circle B = [tex]\pi s^2 \: \rm units[/tex]The rato of the area of the circle A to the area of the circle B is:
[tex]Area(A): Area(B) = \dfrac{\pi r^2}{\pi s^2} = \left( \dfrac{r}{s}\right)^2[/tex]
since we've got [tex]s= 0.8r[/tex], therefore,
[tex]Area(A): Area(B)= \left( \dfrac{r}{s}\right)^2 = \left(\dfrac{r}{0.8r}\right)^2 = \dfrac{100}{64} \\\\Area(A): Area(B)=\dfrac{100}{64} = 100:64[/tex]
Thus, the ratio of the area of circle A to the area of circle B for the considered circle A and B is 100:64

Find the arc length of AB. Round answer to nearest tenth.
Answers
Answer:
9.8 inches
Step-by-step explanation:
Set up a proportion:
central angle / 360 = arc length / circumference
[tex]\frac{80}{360}[/tex] = [tex]\frac{x}{14\pi }[/tex]
360 divided by 14pi is about 8.2, so divide 80 by 8.2 to find x.
x = 9.8 in
Answer:
9.8 inches
Step-by-step explanation:
The formula for arc length is (θ/360)2πr
This is where θ represents the measure of the central angle in degrees,
and r represents the radius of the circle.

Test whether the following functions are analytic exp(x).(cos y + i sin y)
Answers
Answer:
The given f(z) is analytic function
i) δU/δx = eˣ (cos y) = δV/δy
ii) δU/δy = eˣ (-sin y) = - δV/δx
Hence the CR - equations are satisfied
Step-by-step explanation:
Explanation:-
Analytic function:-
A point at which an analytic function ceases to posses a derivative is
called a singular point of the function.Thus the necessary and sufficient condition for a complex function f(Z) = U+i V is analytic in a region R are
δU/δx = δV/δy and δU/δy = -δV/δx ( C R equations)
Given f(Z) = eˣ(cos y+ i sin y)
Let U = eˣ(cos y) ....(i)
and
V = eˣ(sin y) ....(ii)
Differentiating equation(i) partially with respective to 'x'
δU/δx = eˣ (cos y)
Differentiating partially equation(i) with respective to 'y'
δU/δy = eˣ (-sin y)
Differentiating equation(ii) partially with respective to 'x'
δV/δx = eˣ (sin y)
Differentiating equation(ii) partially with respective to 'y'
δV/δy = eˣ (cos y)
Now
δU/δx = eˣ (cos y) = δV/δy
i) δU/δx = δV/δy
δU/δy = eˣ (-sin y) = - δV/δx
ii) δU/δy = - δV/δx
Hence the CR - equations are satisfied

What are trigonometric relations?Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the distance between the maximum of a sine or cosine graph be A
Now , the maximum of sine graph is when θ = 90°
So , sin 90° = 1
The sine function ranges between -1 and 1, so the minimum is -1 and the maximum is 1
And , the maximum of cos graph is when θ = 360°
So , cos 360° = 1
Maximum value of cos θ is 1 when θ = 0˚, 360˚. Minimum value of cos θ is –1 when θ = 180 ˚.
Hence , amplitude represents half the distance between the maximum of a sine or cosine graph

One vertex of a triangle is located at (0,5) on a coordinate

Which transformations could have taken place? Select
two options.
Ro, 90°
Ro, 180°
Ro, 270°
U
Ro -90°
Ro -180°
Answers
Answer: Ro, 270° and Ro -90°
Step-by-step explanation: If the vertex is at 5 on the y-axis at (0,5) and the transformation has moved the vertex to (5,0) it is now at +5 on the x-axis. This is a rotation around the origin, Rotation notation Ro.
This is fairly easy to visualize: like the hand of an analog clock moving from 12 o'clock to 3 o'clock.
In geometry, rotations are given in degrees, moving counter-clockwise. There are 360° in a circle.
Moving 3/4 of the way around the circle counterclockwise.
Multiply(3/4)(360) = 270. This is a positive rotation, counter-clockwise
Clockwise, it is 1/4 of the circle, so Multiply (1/4)(360)= 90 But remember to add the negative sign because clockwise is considered a negative rotation.
Ro, -90°
The transformations that could have taken place are Ro, 270° and Ro -90°
How to determine the transformationsThe vertex of the triangle is given as: (0,5)
After transformation, the vertex of the image is given as: (5,0)
The transformation follows the rule:
[tex](x,y) \to (y,x)[/tex]
The above rule represent:
90 degrees counterclockwise rotation270 degrees clockwise rotationHence, the true statements are Ro, 270° and Ro -90°

Al mediodía me he comido la mitad de una tortilla de patatas. A la hora de la merienda, Ana ha tomado un tercio de la tortilla original, y para cenar, Luis se ha tomado tres cuartas partes de lo que quedaba. ¿Qué fracción de la tortilla queda al final del día?
Answers
Answer:
[tex]\frac{1}{24}[/tex]
Step-by-step explanation:
La mitad es 1/2 y un tercio es 1/3. Como una persona se comió 1/2 y Ana 1/3, puedes determinar lo que se comieron sumando:
[tex]\frac{1}{2}[/tex]+[tex]\frac{1}{3}[/tex]=[tex]\frac{3+2}{6}[/tex]=[tex]\frac{5}{6}[/tex]
Como se comieron 5/6, puedes restar esto de 6/6 para determinar cuanto quedó de la tortilla:
[tex]\frac{6}{6}-\frac{5}{6}= \frac{6-5}{6} =\frac{1}{6}[/tex]
De acuerdo a esto, quedó 1/6 de la tortilla. Luis tomó tres cuartas partes de lo que quedaba, lo que significa que quedó 1/4 de 1/6. Para encontrar la fracción de la tortilla que quedó puedes dividir 1/6 entre cuatro para saber a cuanto corresponde una cuarta parte de 1/6:
[tex]\frac{1}{6}[/tex]÷4= [tex]\frac{1/6}{4}= \frac{1}{6*4}=\frac{1}{24}[/tex]
De acuerdo a esto, la fracción de la tortilla que quedó al final del día es [tex]\frac{1}{24}[/tex].
