Given:
second term = 18
fifth term = 144
The nth term of a geometric sequence is:
Hence, we have:
Divide the expression for the fifth term by the expression for the second term:
Substituting the value of r into any of the expression:
Hence, the explicit rule for the sequence is:
9514 1404 393
Answer:
B. 49/2 units squared
Step-by-step explanation:
The area is that of a triangle 7 units wide and 7 units high. Its area is given by the formula ...
A = 1/2bh
A = (1/2)(7 units)(7 units) = 49/2 units squared
If you would like to find a pair of equations that best models the relationship between p and d, you can do this using the following steps:
p is 2 more than d ... p = d + 2
p is 1 less than d ... p = d - 1
The correct result would be p = d + 2 and <span>p = d - 1.</span>
Answer:
60,000
Step-by-step explanation:
Let the total people in the household be 100%
If 80 percent of the households have cable television, 60 percent of the households have videocassette recorders and the number of households that have both cable television and videocassette recorders is 'x' percent. The number of households having ONLY cable television will be 80-x while households having ONLY videocassette will be 60-x.
To get x, we will have;
80-x + 60-x + x = 100
140-x = 100
x = 140-100
x = 40
This shows that 40% of the households have both cable television and videocassette.
If there are 150,000 households in the city, then the number of households that have both cable television and videocassette recorders could be 40% of 150,000
= 40/100 × 150,000
= 60,000
Number of households that owns both television and videocassette could be from 60,000.
