Answer:

2

Step-by-step explanation:

<u>Since it is AP, the common difference is same for any term:</u>

  • (4x - 2) - (x + 1) = (6x - 3) - (4x - 2)
  • 3x - 3 = 2x -1
  • 3x - 2x = 3 - 1
  • x= 2

<u>The first 3 terms are:</u>

  • 3, 6, 9

<u>Since the last term is 18, it means this AP has 6 terms:</u>

  • {3, 6, 9, 12, 15, 18}

<u>Answer: </u>as we need to find the value of x only, it is = 2

Answer:

a    true

b   false

c.    false

d.   true

e.    false

f.   true

Step-by-step explanation:

The function is y =35+8x where x is the number of items sold and y is the earnings

To determine if the point is on the graph substitute the point in and see if it is true

a (7,91)

91 = 35+ 8(7)

91 = 35+ 56  

91 = 91   true

b(11, 121)

121 = 35+ 8(11)

121 = 35+ 88  

121 = 123   false

c. (9, 110)

110 = 35+ 8(9)

110 = 35+ 72  

110 = 107   false

d. (4,67)

67 = 35+ 8(4)

67 = 35+ 32  

67 = 67   true

e. (5,72)

72 = 35+ 8(5)

72 = 35+ 40  

72 = 75   false

f. (3, 59)

59 = 35+ 8(3)

59 = 35+ 24  

59 = 59   true

What is the correct order of steps for bisecting angle ABC?
Marizza181 [45]

The correct order for bisecting angle ABC is F D E B C A. Option D

<h3>Steps in bisecting angles</h3>

The steps involved in bisecting angles are;

  • Place compass point on the vertex of the angle (point B).
  • Stretch the compass to any length that will stay OF the angle
  • Swing an arc so the pencil crosses both sides (rays) of the given angle. You should now have two intersection points with the sides (rays) of the angle
  • Place the compass point on one of these new intersection points on the sides of the angle. Stretch the compass to a sufficient length to place your pencil well into the interior of the angle, this should be within the rays of the angle
  • Place an arc in this interior
  • Without changing the span on the compass, place the point of the compass on the other intersection point on the side of the angle and make a similar arc. The two small arcs in the interior of the angle should be intersecting
  • Connect the vertex of the angle (point B) to this intersection of the two small arcs

From the listed steps, the correct order for bisecting angle ABC is F D E B C A. Option D

Find the volume of the cylinder. What is the exact volume in terms of π? (diameter= 16m) Options a.) 1000pi cubic m b.) 1024pi c
Kazeer [188]
The volume for any cylinder, right or oblique, would be base x height. Even though an oblique cylinder looks quite different from a right cylinder, their volumes would be equal (given that their radius and height are equal). Think about it, the area of a parallelogram would equal the area of the rectangle if their heights and bases were the same, so that would apply for this also.

V= Bh
The base would stand for that top and bottom of the cylinder, or the circles. The volume for circle is pi x radius squared. 
V = \pi  r^{2}h
V = \pi256 x 16
V = \pi4096 m^{3}
