the volume of a rectangular pyramid with a length of 7 feet, a width of 6 feet, and a height of 4.5 feet.
MatroZZZ [7]

Answer:

Volume = 63 feet

Step-by-step explanation:

To find the volume of a cube or a rectangular prism, the formula is

(L x W x H)/3. In other words, it is the length of the prism, times the width of the prism, times the height of the prism, whole divided by three, since it has a "triangular shape."

Let's substitute in values for these letters, L, W, and H. You said the length was 7, the width was 6, and the height was 4.5. Therefore, it will result in

(7 x 6 x 4.5)/3. That results in 189/3, which is 63.

Hope this helped!!!

A patient has an illness that typically lasts about 24 hours. The temperature, T, in degrees Fahrenheit, of the patient t hours
likoan [24]

Step-by-step explanation:

Given that,

The temperature, T, in degrees Fahrenheit, of the patient t hours after the illness begins is given by:

T(t)=-0.02t^2 +0.4968 t+98 ...(1)

(a) We need to find when does the patient's temperature reach its maximum value.

For maximum value.

Put dT(t)/dt = 0

\dfrac{d(T(t)}{dt}=\dfrac{d}{dt}(-0.02t^2 +0.4968t +98)\\\\=-0.04t+0.4968\\\\-0.04t+0.4968=0\\\\t=12.42\ h

(b) Put t = 12.42 in equation (1) :

T(12.42)=-0.02(12.42)^2 +0.4968 (12.42)+98\\\\=101.08^{\circ} F

Hence, this is the required solution.

2. Which of the expressions below is equivalent to:
jok3333 [9.3K]

Step-by-step explanation:

4\sqrt{27} + 3\sqrt{12}

First, let's rewrite the numbers inside the square roots as factors that include squares:

4\sqrt{9 * 3} + 3\sqrt{4 * 3}

Now, we can take the square root of these squares, while keeping the remaining factor(s) inside of the square root:

(4*3)\sqrt{3} + (3*2)\sqrt{3}

12\sqrt{3} + 6\sqrt{3}

18\sqrt{3}
