Help please!!!!!!!!!!!!!

Answer:

position 1 5 8 12 19 25

term -8 8 20 36 64 88

Step-by-step explanation:

(n - 1) is position ( n ∈ N)

d is the distance between the numbers in the sequence

a1 is the first number in the sequence

we have the fuction: a(n) = a1 + (n - 1)d

see in the table, with position = 1, term = -8 => a1 + d = -8

position = 25, term = 88 => a1 + 25d = 88

=> we have: a1 + d = -8

a1 + 25d = 88

=> a1 = -12

d = 4

=> a(n) = -12 + 4(n - 1)

=> term = 8, position = (8 + 12)/4 = 5

position = 8, term = -12 + 4.8 = 20

term = 36, position = (36 + 12)/4 = 12

position = 19, term = -12 + 4.19 = 64

2(d − 6) − 3 = 1 solve for d

andrey2020 [161]

Answer:

d = 8

Step-by-step explanation:

2(d -6) - 3 = 1

+3 +3

2(d-6) = 4

/2 /2

(d-6) = 2

+6 +6

(d) = 8

d = 8

Helpppppp mathhh failing

LenKa [72]

Sin60 =b/10
√3/2 = b/10
b = √3 / 2 (10)
b = 5√3

d^2 = 10^2 - (5√3)^2
d^2 = 100 - 75
d^2 = 25
d = 5

sin30 = b/a
1/2 = 5√3 / a

a = 5√3 (2)
a = 10√3

c^2 = (10√3)^2 - (5√3)^2
c^2 = 300 - 75
c^2 = 225
c = 15

so
a =10√3, b = 5√3, c = 15,d = 5
answer is
D. last choice

•Rectangular prism - Multiply the measurement of the length times the width, then times the height

•Cube - Since all sides are the same measurement, it would be the measurement of any side, or edge, cubed, or a³

•Prism - Find the area of the base, then multiply the area times the height of the prism. Area would be length times width (B), or B x h

•Triangular prism - Find the area of the base (b), then multiply the area times the length (l) between the triangular bases. Area of the base would be ½ times the base times the height (h) of the triangle, or ½bhl

•Cylinder - Find the area of the circular face using pi times the radius squared, then multiply that area times the height of the cylinder, so πr²h

•Pyramid - Find the area of the base and multiply that area times the height of the pyramid and multiply by 1/3, or 1/3Bh

•Square pyramid - Find the area of the base and multiply that area times the height of the pyramid and multiply by 1/3, or 1/3s²h

•Rectangular pyramid - Find the area of the base and multiply that area times the height of the pyramid and multiply by 1/3, or 1/3 lwh

•Sphere - For a sphere, multiply 4/3 times pi, then time the radius cubed, or 4/3 πr³
