Answer:
C
Step-by-step explanation:
Take a careful look at a(n) = 6(-8)^(n-1).
The first term is 6. This is the result if we let n = 1; 6(-8)^0 = 6(1) = 6. Thus, we can immediately eliminate possible answer choices A and D.
What's the next term? Knowing that the first term, a(1), is 6, the next term is found by multiplying this 6 by (-8)^1, obtaining -48.
The next (third) term is found by multiplying this -48 by (-8)^2, obtaining -48*(+64), or - 3072.
Note that the sign of (-8)^(n-1) alternates, being odd when n-1 is odd and even when n-1 is even.
Answer C is the correct one.
Answer:
A rectangular prism has 3 measurements: length (l), width (w), and height (h)
The volume of a rectangular prism has the formula: V=lwh
The area of the base of the rectangular prism is its length times its width; or
Area of base = lw
So, the volume of the rectangular prism can be written as:
Volume = area of the base * height
Substitute in your numbers:
192=48*h
h=192/48
h=4
So the height is 4 feet

32*1.2=38.4 (.2 is the 20%, and the 1 adds the percent to the original cost making it a mark up)
The missing pieces strategy is another method to compare two fractions. To tell which number is larger, you need to see which one is missing less. For example, you have 3/4 versus 4/5. Each of these fractions needs 1 to complete the whole. You need to subtract the numerator with one to compare them. For 3/4 we have 1/4 and for 4/5 we have 1/5. You know that if you complete 4/5 you will get 4. You know that 5 is greater than four. Therefore, 4/5 is larger than 3/4.
