Answer:
An equation for the nth term of the arithmetic sequence.
Step-by-step explanation:
Given the sequence
2,5,8,11,...
An arithmetic sequence has a constant difference 'd' and is defined by
here
computing the differences of all the adjacent terms
- d = 5-2 = 3, d = 8-5=3, d=11-8=3
Using the nth term formula
substituting a₁ = 2, d = 3
Thus, an equation for the nth term of the arithmetic sequence.
Answer:
2 inches
Step-by-step explanation:
Since his actual height was 4 feet and 2 inches, instead of the estimate of 4 feet, the difference was 2 inches.
This means the error in inches was also 2 inches, since the estimated height was 2 inches lower than the one at the doctor's office.
So, the error is 2 inches
Answer:
(2.4,1.8)
Step-by-step explanation:
the answer is in the image above
Answer:
Step-by-step explanation:
(1, 2) (2, 7)
(7-2)/(2 - 1) = 5/1= 5
y - 2 = 5(x - 1)
y - 2 = 5x - 5
y = 5x - 3
Answer:
old town has 150 steps
Step-by-step explanation:
Let the number of steps in the old tower be m
Mathematically, time = distance/speed
In this case, the distance is the number of steps while the speed is the rate of climbing or descending
For climbing, time spent = m/3
For descending time spent = m/2
Since it took her 25 longer when descending;
This means that;
m/2 - m/3 = 25
(3m-2m)/6 = 25
m/6 = 25
m = 6 * 25
m = 150 steps
