If g(x) + x cos(g(x)) = x3, find g ′(0).
Looks like the equation is
[tex]g(x) + x \cos(g(x)) = x^3[/tex]
Differentiate both sides with respect to x, using the chain rule on the left side:
[tex]g'(x) + \cos(g(x)) - x \sin(g(x)) g'(x) = 3x^2[/tex]
Solve for g'(x) :
[tex]g'(x) (1 - x \sin(g(x))) = 3x^2 - \cos(g(x)) \\\\ g'(x) = \dfrac{3x^2 - \cos(g(x))}{1 - x \sin(g(x))}[/tex]
When x = 0, we have
[tex]g'(0) = \dfrac{0-\cos(g(0))}{1-0\sin(g(0))} = \boxed{-\cos(g(0))}[/tex]
(This is all you can say without providing the value of g (0).)

9514 1404 393
Answer:
3. yes: a[1] = -8, a[n] = a[n-1] +7; an = -8 +7(n -1)
4. no (no common difference)
Step-by-step explanation:
An arithmetic sequence is one in which each term has the same difference from the term before it.
__
3. -1 -(-8) = 7; 6 -(-1) = 7; 13 -6 - 7. The differences are all 7, so the terms have a common difference. This sequence is arithmetic.
The general form of the recursive rule for an arithmetic sequence with first term a1 and common difference d is ...
a[1] = a1; a[n] = a[n-1] +d . . . . . recursive rule
a[1] = -8; a[n] = a[n-1] +7
The general form of the explicit rule for an arithmetic sequence is ...
an = a1 +d(n -1)
an = -8 +7(n -1)
__
4. The differences are ...
8 -1 = 7; 27 -8 = 19; 81 -27 = 54 . . . the differences are not common
This sequences is not arithmetic.
Three teams, A, B and C, play in a competition.
games won by A: games won by B = 4:3
games won by B: games won by C = 5:2
Team B has won 30 games.
In total, how many games have the three teams won?
ANSWER:
43
Explanation:
A : B : C
4 : 3
5 : 2
A × B → 4 × 5 = 20
B × B → 3 × 5 = 15
B × C → 3 × 2 = 6
A : B : C
20 : 15 : 6
B = 15 = 30
what of teams A and C together?
If 15 = 30games, what about 26games?
Cross multiply.
15 × 26 =13
30
So, games won by Team B + games won by Teams A and C
30games + 13games
=43games.

A graphing calculator provides a quick and easy solution to a system of equations. There are many calculators and apps and on-line sites that can solve a system of equations for you.
For the pair of equations in part A, you can eliminate the y-variable by adding 2 times the first equation to 3 times the second equation:
2(2x -3y) +3(3x +2y) = 2(12) +3(31) ⇒ 13x = 117 ⇒ x = 9
Substituting in the first equation gives ...
2(9) -3y = 12 ⇒ 6 -y = 4 ⇒ y = 2
__
For the paired equation in part B, the ratio of the x- and y-coefficients is 6/-9 = -2/3, the same as it is for the given equation. The constants are different (even after dividing the second equation by 3), so the lines are parallel (not coincident). This means the system of paired equations has no solution.

3. A rectangular garden has an area of 40m² and a perimeter of 26m. The length of the
garden is a cm and its width is b cm.
(a) Form two equations involving a and b.
(b) Solve these equations simultaneously in order to find the length and width
of the garden
Answer:
a) a +b= 13, ab= 40
b) length= 8m, width= 5m
Step-by-step explanation:
Perimeter of rectangle= 2(length +width)
Area of rectangle= length ×width
a) Perimeter= 26m
2(a +b)= 26
Divide both sides by 2:
a +b= 26 ÷2
a +b= 13 ----- (1)
Area= 40m²
ab= 40 ----- (2)
b) From (1): a= 13 -b ----- (3)
Substitute (3) into (2):
(13 -b)(b)= 40
Expand:
13b -b²= 40
b² -13b +40= 0
Factorise:
(b -5)(b -8)= 0
b -5= 0 or b -8= 0
b= 5 or b= 8
Substitute into (3):
a= 13 -5 or a= 13 -8
a= 8 or a= 5
Since the length is usually the longer side of the rectangle, the length and the width of the rectangular garden is 8m and 5m respectively.
Answer:
Step-by-step explanation:
Perimeter = 2length + 2 width
2a + 2b = 26 m
Divide the equation by 2
[tex]\dfrac{2a}{2}+\dfrac{2b}{2}=\dfrac{26}{2}\\\\[/tex]
a + b = 13 --------------(I)
a = 13 -b
Area = length *width
a*b = 40 sq.m
ab = 40 ----------------(II)
Plugin a = 13 -b in the equation (II)
(13 - b)*b = 40
13*b - b*b = 40
13b - b² = 40
0 = 40 + b² - 13b
b² - 13b + 40 = 0
Sum = - 13
Product = 40
Factors = (-8) , (-5) {-8 + (-5) = -13 & (-5)*(-8) = 40}
b² - 8b - 5b + (-8)*(-5) = 40
b(b - 8) - 5(b - 8)= 0
( b - 8) (b - 5) = 0
b - 8 =0 ; b -5 =0
b= 8 ; b = 5
Length = 8 cm
Width = 5cm

An herbalist is mixing a 9-kilogram batch of a medicinal blend. The blend, which costs $25.05 per kilogram to make, is made up of ground ginseng at $33.85 per kilogram and golden chia at $16.25 per kilogram. How many kilograms of each should be used to make the 9-kilogram batch?
Write your answers as whole numbers or as decimals rounded to the nearest tenth.
For 9 Kg ground ginseng needed =304.7
For 9 Kg golden chai needed =146.2
For the blend =225.5
What is Unitary Method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
given:
The blend, which costs $25.05 per kilogram.
For 9 Kg ground ginseng needed = 33.85* 9 =304.65 = 304.7
For 9 Kg golden chai needed = 16.25 * 9= 146.25=146.2
For the blend = 25.05 * 9= 225.45=225.5

Find the measure of the angle indicated by 19x+5.
Answer:
100
Step-by-step explanation:
16x + 19x + 5 = 180 {co-interior angles are supplementary}
Combine like terms;
35x + 5 = 180
Subtract 5 from both sides
35x = 180 - 5
35x = 175
Divide both sides by 35
x = 175/35
x = 5
19x + 5 = 19*5 + 5
= 95 + 5
= 100
Answer:
100⁰
Step-by-step explanation:
co interior angles add up to 180⁰
so l9x+5+16x=180⁰
35x+5⁰=180⁰
35x=180⁰-5⁰
35x=175⁰
Divide both side by the co-efficient of x which is 35
35x/35=175⁰/35⁰
x=5
Now to find the value of 19x+5,we have to substitute any x in it by 5
so 19x+5
19(5)+5
95+5
