Answer:
A
Step-by-step explanation:
Start with the 3.
You know that there is a difference of 4 between (say) 2 and 5. The 3 is a sign that the sequence is increasing. The members of the sequence are going up.
n - 1 means that the nth terms is calculated as an and uses the number of terms to be n-1. That means that the first term is a1 which is the starting point of the sequence.
The answer is an = a1 + (n-1)*d
d = 3
a1 = - 7
So let's try the formula out.
a4 = -7 + (4 - 1)*3
a4 = -7 + 3 * 3
a4 = -7 + 9
a4 = 2
Is 2 the 4th term in the series? Yes it is!
Answer:
17.3 ft
Step-by-step explanation:
To find the second leg, use the following: √c² - a². Substitute c for 28, and a for 22.
b = √28² - 22² <em>{Square 28 to get 784, and square 22 to get 484.}</em>
b = √784 - 484 <em>{Subtract 484 from 784 to get 300.}</em>
b = √300 <em>{Find the square root of 300.}</em>
b = 17.32051 <em>{Round to the nearest tenth.}</em>
b = 17.3 ft.
The bottom of the ladder will be 17.3 ft from the bottom of the building.
