Good evening ,
Answer:
Is his formula correct and how do you know : <em>Yes</em>
Is it an explicit or recursive formula : <em>explicit </em>
Step-by-step explanation:
an = a1 + (n-1)r
a1 = 5
r = 8-5 = 3
Then an = 5 + 3(n-1).

Answer:
927 cubic inches
Step-by-step explanation:
The area of the octagonal base is ...
A = (1/2)Pa
where P is the perimeter, and 'a' is the apothem. Using the given numbers, the base area is ...
A = (1/2)(8·4)(4.83) = 77.28 . . . square inches
The volume of the prism is given by ...
V = Bh
where B represents the area of the base, and h is the height.
V = (77.28 in^2)(12 in) = 927.36 in^3
The volume of the prism is about 927 cubic inches.
Answer:
Step-by-step explanation:
we are given the base area and the height of a solid figure
since the base area is not perfect square
we assure the solid figure to be a cuboid
remember that,
we are given l×w is 40 and h is 7
so substitute
simplify multiplication:
hence,
the volume of the figure is 280 in³
Answer:
2. power
4. tenth
20. hundred-thousandth
40. 5.063
50. 67/10
Step-by-step explanation:
20. If the underlined digit is the zero, the answer is "hundred-thousandth." It's hard to tell from the picture if zero is the underlined digit.
40. 5 and 63/1000 = 5 + 63/1000 = 5 + 0.063 = 5.063
50. 6.700 = 6700/1000 = 67/10
You need to understand the different kinds of categories in order to solve this problem.
There are:
types of crusts - 3
types of toppings - 5
You multiply these together (3 x 5)
Your answer should be 15
