Step-by-step explanation:
if there are no typos, then the second and the fourth answers are correct.
1 - 1.7 = -0.7 or -2×0.35
-2x = -2(x)
The distance covered by the hiker if he traveled a horizontal distance of 120 ft at and angle of 6° will be given by:
cos θ=adjacent/hypotenuse
let the hypotenuse be h, adjacent =120 ft, θ=6°, thus plugging in the values we shall have:
cos 6=120/h
h=120/cos 6
h=120.661 ft
Answer: 120.661 ft
Random digit dialing<span> (RDD) is a method for selecting people for involvement in telephone statistical surveys by generating telephone numbers at </span>random<span>. </span>Random digit dialing<span> has the advantage that it includes unlisted numbers that would be missed if the numbers were selected from a phone book.</span>
Answer:
x=2/3
Step-by-step explanation:
(2x+1)/2 = 2 1/3/4
Multiply 4 on both sides:
2x+1=2 1/3
Rewrite:
2x+1=7/3
Subtract 1 on both sides:
2x=4/3
Divide 2 on both sides:
x=2/3
Thus x=2/3
Hope this helps!
Answer:
Common ratio is 3
The three terms are 162, 486, 1458
Step-by-step explanation:
Given: The first 4 terms of a sequence are ![2,6,18,54](https://tex.z-dn.net/?f=2%2C6%2C18%2C54)
To find:
A. the common ratio
B. the next 3 values in the geometric sequence
Solution:
Geometric sequence is a sequence in which each of the terms is obtained by multiplying the previous term by a fixed number.
A.
![\frac{6}{2}=3\\\\\frac{18}{6}=3\\\\\frac{54}{18}=3](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B2%7D%3D3%5C%5C%5C%5C%5Cfrac%7B18%7D%7B6%7D%3D3%5C%5C%5C%5C%5Cfrac%7B54%7D%7B18%7D%3D3)
So, the common ratio is ![3](https://tex.z-dn.net/?f=3)
B.
The next three values are as follows:
![54(3)=162\\162(3)=486\\486(3)=1458](https://tex.z-dn.net/?f=54%283%29%3D162%5C%5C162%283%29%3D486%5C%5C486%283%29%3D1458)
