Step-by-step explanation:
Well, it's hard to generalize this. But I can show you a few examples using the power rule and some derivatives of trig functions. Lets say we have a function:
[tex]f(x) = {x}^{n} [/tex]
Then you should know it's derivative is:
[tex] \frac{df}{dx} = n {x}^{n - 1} [/tex]
For polynomial functions, a subtraction of 1 from the exponent will turn any odd function into an even, and any even function to an odd. An example of this is x^3, which is odd. The derivative is 3x^2, which is even. Another example, this time of a trig function, is sine and cosine. Sine is odd, while cosine is even. The derivative of sine is cosine, and the derivative of cosine is negative sine.

A pyramid has a square base that has an area of 144 square feet. If the slant height of each triangular face is 10 in, what is the total surface area of the pyramid?
Answer:
Total Surface Area
= 384 sq ft
Step-by-step explanation:
To find Total Surface Area, add up the areas of all the sides of the shape. A square based pyramid has five sides, a square bottom and four triangular sides. Luckily all four sides are the same, so just one calculation for these.
Area of square base is given.
A = 144 sq ft
Since the base is a square the length of the side of the square is 12, because 12×12 is 144.
The side of the square base is the base of the triangular side.
Area of a triangle:
A = 1/2•b•h
A = 1/2(12)(10)
A = 60
The area of one triangular face is 60. There are four of these.
A = 4(60)
A = 240
This is the area of all the triangular faces.
Add them all up.
A (TOTAL)
= 144+240
= 384 sq ft

A cuboid with a volume of 374cm^3 has dimensions 2cm,(x+3)cm and (x+9)cm
Please help me get the full 7 marks
Answer:
x² + 12x - 160 = 0
x = 8 or x = -20
The dimensions are 2 cm, 11 cm, 17 cm.
Step-by-step explanation:
The volume of the cuboid is the product of the three dimensions.
volume = 2(x + 3)(x + 9)
volume = 2(x² + 12x + 27)
volume = 2x² + 24x + 54
We are told the volume equals 374 cm³.
2x² + 24x + 54 = 374
2x² + 24x - 320 = 0
x² + 12x - 160 = 0
(x - 8)(x + 20) = 0
x - 8 = 0 or x + 20 = 0
x = 8 or x = -20
We do not use x = -20 because it would cause two dimensions to be negative which cannot be.
x = 8
x + 3 = 8 + 3 = 11
x + 9 = 8 + 9 = 17
The dimensions are 2 cm, 11 cm, 17 cm.

1. [15 points] An electric company makes motors for a variety of applications. Its two plants ship their production to three dealers. The production hours available in the plants for the second quarter vary because of downtime for scheduled maintenance on equipment: Plant April May June A 400 360 360 B 425 350 375 Plant A requires 20 hours to produce a motor. Plant B requires 25. Because B is older and less efficient, production costs are $100 more per motor in B than in A. Shipping costs from the plants to the dealers and orders for the quarter are show below Monthly Shipping orders costs from Dealer April May June A B 1 12 9 11 45 60 2 10 12 8 50 70 3 8 11 12 75 40 Building ahead and stockpiling of motors is possible with a cost of $55 per month. Orders that are not shipped in the month requested are subject to a contractual penalty of $80 per month. At the end of June all orders need to be satisfied. Formulate an LP problem that can determine a production schedule to meet the demands for the motors with the minimum total of shipping, storage, penalty and production differential costs.

Solve the equation by factoring. z2 – 6z – 27 = 0
z = –3 or z = 9
z = –3 or z = –9
z = 3 or z = –9
z = 3 or z = 9
Answer:
The value of z = -3 or z = 9
Step-by-step explanation:
Given equation => z² – 6z – 27 = 0
=> z² - 9z + 3z - 27 = 0
=> z(z -9 ) +3 (z - 9 ) = 0
=> (z + 3) (z - 9)
=> z = -3 or z = 9

Answer:
(a) graph iii)
(b) graph v)
(c) graph ii)
(d) graph iv)
Step-by-step explanation:
All given equations are in vertex form: y = (x - h)² + k
where (h, k) is the vertex of the parabola
The vertex is the turning point of the parabola, so the minimum point for parabolas that open upward, and the maximum point for parabolas that open downward.
Vertices of the given graphs:
i) (-3, 2)
ii) (-3, -2)
iii) (2, 3)
iv) (3, 2)
v) (-2, -3)
vi) (2, -3)
Part (a)
Given equation: y = (x - 2)² + 3
Therefore, the vertex is (2, 3) → graph iii)
Part (b)
Given equation: y = (x + 2)² - 3
Therefore, the vertex is (-2, -3) → graph v)
Part (c)
Given equation: y = (x + 3)² - 2
Therefore, the vertex is (-3, -2) → graph ii)
Part (d)
Given equation: y = (x - 3)² + 2
Therefore, the vertex is (3, 2) → graph iv)

Question (a)
Factored
Factor [tex]y=x^2+2x-8[/tex]
[tex]ac=-8[/tex] and [tex]d+e=2[/tex]
[tex]\implies d=4[/tex] and [tex]e=-2[/tex]
Rewrite [tex]2x[/tex] as [tex]+4x-2x[/tex]:
[tex]\implies x^2+4x-2x-8[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\implies x(x+4)-2(x+4)[/tex]
Factor out common term [tex](x+4)[/tex]:
[tex]\implies (x-2)(x+4)[/tex]
Zeros
[tex]\implies (x-2)=0\implies x=2[/tex]
[tex]\implies (x+4)=0\implies x=-4[/tex]
Vertex
[tex]\sf x-value=\dfrac{2+(-4)}{2}=-1[/tex]
[tex]\sf y-value=(-1)^2+2(-1)-8=-9[/tex]
Vertex = (-1, -9)
-------------------------------------------------------------------------------------
Question (b)
Factor [tex]y=-x^2-9x-14[/tex]
[tex]ac=14[/tex] and [tex]d+e=-9[/tex]
[tex]\implies d=-7[/tex] and [tex]e=-2[/tex]
Rewrite [tex]-9x[/tex] as [tex]-7x-2x[/tex]:
[tex]\implies -x^2-7x-2x-14[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\implies -x(x+7)-2(x+7)[/tex]
Factor out common term [tex](x+7)[/tex]:
[tex]\implies (-x-2)(x+7)[/tex]
Factor [tex](-x-2):-(x+2)[/tex]
[tex]\implies -(x+2)(x+7)[/tex]
Zeros
[tex]\implies -(x+2)=0\implies -x-2=0 \implies x=-2[/tex]
[tex]\implies (x+7)=0\implies x=-7[/tex]

[tex]\sf x-value=\dfrac{-2-7}{2}=-4.5[/tex]

Luke and Ella have money in their bank account in the ratio 7:8
Luke gives £2 to Ella, and the ratio becomes 4:5.
Work out the original amount of money that Ella had.
Answer:
$48
Step-by-step explanation:
Ratios can be written as fractions.
1) Initially, Luke had 7x money, Ella had 8x money. Luke gives $2 to Ella. So, Luke now has 7x - 2 money and Ella has 8x + 2. The total amount of money is 4:5. These could be shown as fractions.
7x - 2/8x + 2 = 4/5
4(8x + 2) = 5(7x - 2)
32x + 8 = 35x - 10
8 + 10 = 35x - 32x
18 = 3x
18/3 = x
x = 6
2) Substitute the result (x = 6) into 7x:8x.
= 7(6)
= 42
= 8(6)
= 48
