Answer:
2
Step-by-step explanation:
The common ratio of the sequence is 2 because between each term you are multiplying by 2 to get the next term
Answer:
C
Step-by-step explanation:
To Solve, just cube the terms on the right side to see if they go back to the number on the left.
The first part is true because multiplying 11 * 11 * 11 = 1331.
The second part is true because multiplying 5 * 5* 5 = 125.
The third part is false because multiplying 8 * 8 * 8 = 512.
The fourth part is true because multiplying 1 * 1* 1 = 1.
A = LW
A = 72
L = W + 1
72 = W(W + 1)
72 = W^2 + W
W^2 + W - 72 = 0
(W + 9)(W - 8) = 0
W + 9 = 0
W = -9......extraneous solution...does not work here
W - 8 = 0
W = 8 <==
L = W + 1
L = 8 + 1
L = 9
so the width (W) is 8 ft and the Length is 9 ft
Answer:
P = 57°
Step-by-step explanation:
Given the following :
PQ = 17
QR = 15
PR = 14
Using the cosine formula since the length of the three sides are given:
a2 = b2 + c2 – 2bccos(A)
To find P:
QR^2 = PQ^2 + PR^2 – 2(PQ)(PR)cos(P)
15^2 = 17^2 + 14^2 – 2(17)(14)cos(P)
225 = 289 + 196 - 476 cosP
476*CosP = 485 - 225
476*CosP = 260
CosP = 260/476
CosP = 0.5462184
P = Cos^-1(0.5462184)
P = 56.892029
P = 57°
Infinite i think. because the two equations are the same.
