6) The cost of a computer system increases with increased processor speeds. The cost C
of a system as a function of processor speed is estimated as C = 1234 - 35 + 1900,
where S is the processor speed in MHz. Find the processor speed for which cost is at a
minimum. [4 marks]
Answer:
The speed is: 0.0142MHz
Step-by-step explanation:
Given
[tex]C(s) = 1234s^2 - 35s + 1900[/tex]
Required
The processor speed when the cost is at minimum
First, differentiate C(s) with respect to s
[tex]C(s) = 1234s^2 - 35s + 1900[/tex]
[tex]C'(s) = 2468s - 35[/tex]
The cost is at minimum when [tex]C'(s) = 0[/tex]
So, we have:
[tex]C' = 2468s - 35 = 0[/tex]
[tex]2468s - 35 = 0[/tex]
Solve for s
[tex]2468s = 35[/tex]
[tex]s=\frac{35}{2468}[/tex]
[tex]s\approx0.0142[/tex]

Answer:
V=385 cubic units
Step-by-step explanation:
The volume of a rectangular prism is given by the formula [tex]V=lwh[/tex], where l is the length, w is the width, and h is the height. Our dimensions are 5, 7, and 11. So, we have to multiply them to find the volume.
5 × 7 × 11 = 385
Thus, the volume of the rectangular prism is 385 cubic units.

Answer:
1. False
Sketch pads ordered: 10(90/3) = 10×30 = 300
2. True
Painting jars ordered: 8(90/5) = 8×18 = 144
3. True
(25×12)/(12×12) = 300/144

Step-by-step explanation:
The volume of the rectangular pyramid is calculated as
V = [tex]\frac{1}{3}[/tex] Ah ( A is the area of the base and h the perpendicular height )
Here A = 10 × 6 = 60 ft² and h = 6 , then
V = [tex]\frac{1}{3}[/tex] × 60 × 6 = 20 × 6 = 120 ft³
The volume of the rectangular prism is calculated as
V = 10 × 6 × 4 = 60 × 4 = 240 ft³
Total volume = 120 + 240 = 360 ft³

The top of the cake to be triangular with one side length 10cm, one side length 12cm and a 90-degree angle between these sides
Answer:
See attachment
Step-by-step explanation:
Given

[tex]Side\ 2 = 12cm[/tex]
[tex]\theta = 90^\circ[/tex]
Required [Missing from the question]
Draw the top of the cake
See attachment for reference.
From the attachment,
[tex]2cm = 1\ unit[/tex]
So:
[tex]Side\ 1 = 10cm[/tex]
[tex]Side\ 1 = 5 * 2cm[/tex]
Substitute [tex]2cm = 1\ unit[/tex]
[tex]Side\ 1 = 5 * 1unit[/tex]
[tex]Side\ 1 = 5\ units[/tex]
[tex]Side\ 2 = 12cm[/tex]
[tex]Side\ 2 = 6 * 2cm[/tex]
Substitute [tex]2cm = 1\ unit[/tex]
[tex]Side\ 2 = 6 * 1unit[/tex]
[tex]Side\ 2 = 6\ units[/tex]
This means that, the given side lengths will be represented by 5 units and 6 units on the grid, respectively.

Complete question :
I made a fort by connecting two boxes. The first box is 5 meters long, 9 meters wide, and 9 meters high. The second box is 3 meters long, 8 meters wide, and 2 meters high. How many cubic meters of space does my fort have?
Answer:
453 m³
Step-by-step explanation:
Volume of first box :
Volume = Length * width * height
Volume = 5 * 9 * 9
Volume = 405 m³
Volume of second box :
Volume = Length * width * height
Volume = 3 * 8 * 2
Volume = 48 m³
Total volume :
405m³ + 48m³ = 453m³
