If the <em>n</em>-th term of the sequence is given by <em>n</em> ² - 2, then the 5th term is obtained by simply replacing <em>n</em> with 5 :
5² - 2 = 25 - 2 = 23
Answer:
E. V=225 cm^3.
Step-by-step explanation:
What you do is you use the formula for the volume of a pyramid which is V=lwh/3.
The length is 9 cm.
The width is 5 cm (but remember you have two.)
The height is 3 cm.
<em>V=9*5*5*3/3</em>
<em>V=675/3</em>
<em>V=225 cm^3. Is your answer. </em>
Answer:
the first and second car seats are appropriate for a 33 lb. child. The first seat suits children up to 34 lb. The second seat suits children that weight between 16 to 40 lb.
The only seat that is not appropriate would be the third one that is too large, since children between 34 to 90 lb. should use it.
seat 1 ≤ 34 lb ⇒ simple inequality
16 lb < seat 2 and seat 2 < 40 lb ⇒ compound inequality
34 lb < seat 3 and seat 3 ≤ 90 lb ⇒ compound inequality
