1 answer:
melamori03 [73]4 years ago
6 0

Answer:

D

Step-by-step explanation:

An operation of two real numbers is defined by the rule

a\bigotimes b=b^a+2ab

Calculate 2\bigotimes (1\bigotimes 3). First evaluate the expression in brackets:

1\bigotimes 3=1^3+2\cdot 1\cdot 3=1+6=7

Now,

2\bigotimes (1\bigotimes 3)=2\bigotimes 7=2^7+2\cdot 2\cdot 7=128+28=156

Find the volume of the composite solid.
luda_lava [24]

Answer:

768 m^2

Step-by-step explanation:

<u>Separate the shapes</u>

We can first separate the triangular pyramid from the rectangular prism.

We can calculate them separately.

<u>Calculate</u>

The volume of the triangular pyramid is the base multiplied by the height divided by 3. The base of the pyramid has the same base as the prism so:

8 * 8 = 64

Then we need the height which is 6 so:

64 * 6/3 = 64 * 2 = 128 m^2

Then we calculate the volum of the prism; the formula for that side times side time side:

8 * 8 * 10 = 640 m^2

The total volume is them added up:

128 + 640 = 768 m^2
