The period of an function, is how many times it takes to complete one cycle, if the period is 2π then after 2π the function would have been completed one entire cycle, but what I mean by cycle?

It's when the function start again, these functions are called periodic functions for a reason, after between that interval, the function goes up, goes to 0 again, go down and finally goes zero again, it means a cycle! the function goes up, down and then return to the same point.

If you look at the picture, the function took 2π just to go up and zero, it needs more 2π to go down and return to zero, then it's period is 4π.

The bottom function complete its cycle in just π!

I hope you liked it, maybe the draw will help you!

Answer:

8 square inches

Step-by-step explanation:

when finding the area of a rectangle you multiply the length and width

so the area is equal to 2 x 4

2 x 4 = 8 so the area of the rectangle is 8 square inches

Answer:

23.7°

Step-by-step explanation:

To obtain the value of AB ; Use the cosine rule ;

Recall:

c² = a² + b² - 2ab Cos C

c² = 24² + 11² - 2*24*11 Cos75

c² = 576 + 121 - 528 * 0.2588190

c² = 697 - 136.656432

c² = 560.343568

c = sqrt(560.343568)

c = 23.6715

Hence, c = AB = 23.7°

Step-by-step explanation:

First of a line perpendicular to another line has the inverse opposite slope

    if  m is the slope  m of line 1  the perpendicular line slope is   -1/m

y - 3 = -4(x + 2)    equarion 1

y - 3 = -4x - 8       -4 × (x+2)

y = -4x - 5            added 3 to both sides to get the y intercept form y=mx+b

the slope of the perpendicular line will be   1/4

using the point slope method

y - y1 = m(x -x1)    

the gives the (x,y) point of the perpendicular as (-5, 7)

x1 = -5

y1 = 7

y - 7 = 1/4(x - (-5))

y - 7 = 1/4(x +5)     <--------------   Answer

the attached graph shows the line and the perpendicular going through point (-5, 7)

Answer:

No. Her claim is too large. The actual value is 4 cm.

Because Volume = l³

4³ equals to 64 which means size of the edge is 4cm.

Answer:

median- 58.5

first quartile- 56

third quartile- 65

interquartile range- 9

Step-by-step explanation:

median is when you put the numbers from least to greated and find the middle number; so, you will put this set in that order= 38, 46, 55,56,58,59,61,65,67,75. now, you get stuck between 58 and 59. so you add them and divide by two to get 58.5. thats the median. The first quartile is any number from the set that is smaller than the median, basically the first half of it. now you will just find the median of that which is 56. that is your first quartile. third quartile is the second half of the set, any number in the set that is greater than the median. you will find the median of that half to get 65. that is your 3rd quartile. interquartile range ius the difference bewteen your first and third quartile. 65-56 is 9. hope this helped marck as brainlyest and help me with my que tooo :)

36 is 90% of 40

Answer:

The second one

Step-by-step explanation:

As you can see in the question, it states that 36 is 90% so that means in the model, 36 should be under 90%

Answer:

They ate the same amount of each pie

Step-by-step explanation:

The cherry pie was cut into 6 equal slices and 3 of these slices were eaten so that means there is 1/2 of the pie still left.

The pumpkin pie was cut into 12 equal slices and 6 of these slices were eaten so that also means there is 1/2 of the pie left.

Since both pies still have 1/2 left and they were both the same size then that means the same amount of pie was eaten from both the cherry and the pumpkin.

Hope this helps :)

Answer:

x = 69

y = 69

Step-by-step explanation:

Since AB is parallel to CD

x = 69 ( They are alternate angles)

and

y = 180 - 111 ( Co - interior angles)

y = 69

Answer:

11 ft, 60 ft, 61 ft

Step-by-step explanation:

Use the pythagorean theorem equation
