Answer:

<em>Volume of Figure; 80 cubic inches</em>

Step-by-step explanation:

Calculate the volume of this square pyramid firstly, through the basic volume formula Base * height , but divide by 3 for it is a pyramid, one - third of a cube;

Base ⇒ length * width = 4 in * 4 in = 16 inches^2,

Volume of Square Pyramid ⇒ ( Base * height ) / 3, ( 16 inches^2 * height ) / 3, ( 16 * 3 ) / 3 = 48 / 3 ⇒ <em>16 cubic inches</em>

Now let us compute the volume of this cube, dimensions 4 by 4 by 4 provided a formula Base * height;

Base ⇒ length * width = 4 in * 4 in = 16 inches^2,

Volume of Cube ⇒ ( Base * height ) = ( 16 inches^2 * 4 inches^2 ) = 16 * 4 ⇒ <em>64 cubic inches</em>

The volume of this Composite Figure is thus; Volume of Pyramid + Volume of Cube = 16 in^3 + 64 in^3 = <em>80 cubic inches,</em>

<em>Volume of Figure; 80 cubic inches</em>

$10,000 at an annual rate of 7%, compounded semi-annually, for 2 years
forsale [732]

Answer:

\$13,107.96

Step-by-step explanation:

Since interest is compounded semi-annually (half a year or 6 months), in a spawn of 2 years, the interest will have been compounded 4 times. As given in the problem, each time the interest is compounded, the new balance will be 107% or 1.07 times the amount of the old balance.

Therefore, we can set up the following equation to find the new balance after 2 years:

\text{New balanace}=10,000\text{ (old balance)}\cdot 1.07\cdot 1.07\cdot 1.07\cdot 1.07,\\\text{New balanace}=10,000\cdot 1.07^4=\boxed{\$13,107.96}

The temperature at a point (x, y) is T(x, y), measured in degrees Celsius. A bug crawls so that its position after t seconds is
iren [92.7K]

Answer:

The temperature is increasing at the rate of 6.5 degree celcius per second.

Step-by-step explanation:

We are given the following information:

Temperature of a point is given by T(x,y)

After t seconds a bug reaches a point x = \sqrt{2 + t}, y = 3 + \frac{1}{2}t

At t = 2, x = 2, y = 4

The temperature function satisfies:

T_x(2,4) = 8\\T_y(2,4) = 9

We have to find:

\displaystyle\frac{dT}{dt} = T_t(x(t), y(t))\\\\= T_x(x(t),y(t)).x'(t) + T_y(x(t),y(t)).y'(t) \\\\= T_x(x(t),y(t)).\displaystyle\frac{1}{2\sqrt{(t+2)}} + T_y(x(t),y(t)).\displaystyle\frac{1}{2} \\\\\displaystyle\frac{dT(x,y)}{dt}_{at~t=2} = \displaystyle\frac{dT(2,4)}{dt}_{at~t=2} = 8.\displaystyle\frac{1}{4} + 9.\displaystyle\frac{1}{2} = 2 + 4.5 = 6.5

Hence, the temperature is increasing at the rate of 6.5 degree celcius per second.
