Answer:

V = 3239

Step-by-step explanation:

The volume formula for a regular hexagonal prism is 3√3/2a^2h when you input the values you get 3238.74, rounded to the nearest whole number you get 3239, the student most likely used the radius of the hexagon in the equation instead of the height.

Please mark as brainliest :)

2. A clothing truck is shaped like a rectangular prism. The volume of the truck 576 ft cubed. The length of the truck is 12 ft,
dezoksy [38]

Answer:

The height of the clothing truck is 6 feet

Step-by-step explanation:

Length of truck = 12 feet

Width of truck = 8 feet

Let h be the height of truck

Volume of truck which is shaped like rectangular prism =Length \times Width \times Height

Volume of truck which is shaped like rectangular prism =12 \times 8 \times h

We are given that The volume of the truck 576 ft cubed.

So, 12 \times 8 \times h  = 576

h = \frac{576}{12 \times 8}

h=6

Hence the height of the clothing truck is 6 feet

which geometric series represents 0.4444... as a fraction? a) 1/4, 1/40, 1/400, 1/4,000 b) 1/40, 1/400, 1/4,000, 1/40,000 c) 4/1
xenn [34]

Answer: \frac{4}{10}+\frac{4}{100}+\frac{4}{1,000}+\frac{4}{10,000}


Step-by-step explanation:

The given geometric series are:

a)\frac{1}{4}+\frac{1}{40}+\frac{1}{400}+\frac{1}{4,000}

on simplifying in decimals, we get

0.25+0.025+0.0025+0.00025=0.27775\neq0.4444

b) \frac{1}{40}+\frac{1}{400}+\frac{1}{4,000}+\frac{1}{40,000}

on simplifying in decimals, we get

0.025+0.0025+0.00025+0.000025=0.027775\neq0.4444

c)\frac{4}{10}+\frac{4}{100}+\frac{4}{1,000}+\frac{4}{10,000}

on simplifying in decimals, we get

0.4+0.04+0.004+0.0004=0.4444

Thus, this geometric series represent 0.4444.

d)\frac{1}{10}+\frac{1}{100}+\frac{1}{1,000}+\frac{1}{10,000}

on simplifying in decimals, we get

0.1+0.01+0.001+0.0001=0.1111\ \neq0.4444

Write the definite integral for the summation: the limit as n goes to infinity of the summation from k equals 1 to n of the prod
zlopas [31]

Sounds like you have

\displaystyle\lim_{n\to\infty}\sum_{k=1}^n\left(1+\frac kn\right)^2\frac1n

which translates to the sum of the areas of n rectangles with dimensions \left(1+\dfrac kn\right)^2 (height) and \dfrac1n (width). This is the right-endpoint Riemann sum for approximating the area under x^2 over the interval [1, 2].
