A stick was broken into two pieces. The length of the first piece is 28 cm more than the second piece. The total length of the two pieces is 56 cm. Find the length of the first piece.

If you know your derivative rules, then

d/dx [1/x] = -1/x ²

so that when x = 6, the derivative has a value of -1/36.

If you have to use the definition of the derivative, then

d/dx [1/x] = lim {h → 0} (1/(x + h) - 1/x) / h

… = lim {h → 0} (x - (x + h)) / (hx (x + h))

… = lim {h → 0} (-h) / (hx (x + h))

… = lim {h → 0} (-1) / (x (x + h))

… = -1/x ²

and at x = 6, you again get -1/36.

Alternatively, use the definition of the derivative at a point:

d/dx [1/x] (6) = lim {x → 6} (1/x - 1/6) / (x - 6)

… = lim {x → 6} ((6 - x) / (6x)) / (x - 6)

… = lim {x → 6} -(x - 6) / (6x (x - 6))

… = lim {x → 6} (-1) / (6x)

… = -1/36

What is fraction?

A fraction represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters.

According to questions, Last year Zack had two jobs.

Zack worked  in an office for [tex]12[/tex] months and earned  £[tex]2600[/tex] per month

and at a gym for [tex]39[/tex] weekends and earned £[tex]80[/tex] per weekend.

We have to find the fraction of his total income last year came from his work at the gym.

Office Income[tex]=[/tex]£[tex](2600[/tex]×[tex]12[/tex][tex])[/tex]  [tex]=[/tex]£[tex]31200[/tex]

Gym Income[tex]=[/tex]£ [tex](80[/tex]×[tex]39)[/tex][tex]=[/tex] £[tex]3120[/tex]

Total Income[tex]=[/tex]£ [tex]34320[/tex]

Fraction of his total income last year came from his work at the gym  

[tex]=\frac{3120}{34320} \\=\frac{1}{11}[/tex]

[tex]=0.909[/tex]

Hence, we can conclude that [tex]\frac{1}{11}[/tex] [tex]=0.909[/tex] of his total income last year came from his work at the gym.

Answer:

257.

Step-by-step explanation:

seperate the shapes. we know that the side on the left upper corner is 7 because 29 - 22. The we find the other missing side, which is 26 - 21, 5. then we multiplt the first "box" to find the area, 21 x 7 = 147. Then the second box 5 x 21 = 110. Add the two, and you find your answer. 257

Answer:

x = 10√3

y = 10

Step-by-step explanation:

Step 1:

x = r·cos(30°)

y = r·sin(30°)

Step 2:

x = 20·√3/2 = 10√3

y = 20·1/2 = 10

However, there is a shortcut. Since there is a hypotenuse, there is a 90° angle. You are given a 30° angle, so the triangle is 30°-60°-90°.

The sides of a 30°-60°-90° triangle are in the ratio 1:√3:2.

The side opposite the 90° angle has length 20, so the side opposite the 30° angle has length 10, and the side opposite the 60° angle has length 10√3.

Step-by-step explanation:

Answer:find the solution to the system of equations below.start by adding the equation

{-2x+2y=-8

{2x+y=5

Step-by-step explanation:The given system of equation are:

1----  y= x -4

2----- y=4 x+2

Equation (1) - Equation (2)

→0= x -4 - (4 x+2)

→0=  -3 x -6-----[Adding and subtracting like terms]

Adding 3 x on both sides

→3 x= -6

Dividing by 3 on both sides

→x = -2

→Substituting the value of x in equation 1, we get

y= -2 -4

y =-6

→Solution set =(x,y)=(-2, -6)

Don't used the graph to find the solution.
