Answer:

Derivative of i is y' =1 - [tex]\frac{1}{x^{2} }[/tex]

As for the second function, I'm confused by what you typed please retype it correctly so I can solve

Step-by-step explanation:

Work for the first derivative:

i. y = x - (1/x) = x - [tex]x^{-1}[/tex]

y' = [tex]x^{1-1} = x^{0} = 1\\\\\\x^{-1-1} =x^{-2} = \frac{1}{x^{2} }[/tex]

y' = [tex]1 -\frac{1}{x^{2} }[/tex]

Answer:

4/3

Step-by-step explanation:

Scale factor is a ratio of the length of side in one object to the length of a corresponding side of the other object.

In this case, the scale factor will be the ratio of the new dilated pupil size of the patient to the previous size of the pupil

This will be : 8/6 = 4/3

The scale factor is : 4/3

Answer:

1) The first term is $138

2) The difference is $55

3)  The iterative rule for the amount of money Mrs. Speas has after n weeks is 27.5·n² + 110.5·n

Step-by-step explanation:

The mount Mrs. Speas has in her bank account = $138

The amount of money she deposits each week = $55

The amount of money in Mrs. Speas account therefore, forms an Arithmetic Progression

1) The first term = a = The initial money Mrs. Speas has in her bank account = $138

2) The (common) difference = d =The amount she deposits at the end of each week = $55

The iterative rule for the amount of money Mrs. Speas has (in her bank account) after n weeks is given by the formula for the sum of an arthmetic progression (AP), Sₙ, as follows;

[tex]S_n = \dfrac{n}{2} \times \left [2 \times a + (n - 1)\times d \right ][/tex]

Substituting the values of a and d gives;

[tex]S_n = \dfrac{n}{2} \times \left [2 \times 138 + (n - 1)\times 55 \right ] = \dfrac{n}{2} \times \left [221 + n \times 55 \right ] = 110.5\cdot n + 27.5 \cdot n^2[/tex]

∴ 3)  The amount of money she has after n weeks = Sₙ = 27.5·n² + 110.5·n.

Answer:

Step-by-step explanation:

Since, the function given in the graph is a piecewise function,

Piece 1 is defined in the domain → -9 ≤ x ≤ -3

Piece 2 is defined in the domain → -3 < x ≤ 4

Piece 3 defined in the domain → 4 < x < 9

x = -3.0001 is lying on piece 1,

f(-3.0001) = 3

x = 3.999 is lying on piece 2,

f(3.999) = 7

x = 4.0001 is lying on piece 3,

f(4.0001) = -3

x = 9 doesn't represent any piece,

f(9) = Undefined

Answer:

The statement which justifies Andrea's statement is "Corresponding angles are congruent" ⇒ C

Step-by-step explanation:

If two parallel lines intersected by a line, then there are some pair of angles are formed

In the given figure

∵ Lines l and m are parallel

∵ They are cut by transversal p

∵ ∠2 and ∠3 are in the corresponding position

→ By using the 1st rule above

∵ Corresponding angles are congruent

∴ ∠2 ≅ ∠3

∴ m∠3 = m∠2

∵ m∠2 = 40°

∴ m∠3 = 40°

The statement which justifies Andrea's statement is "Corresponding angles are congruent"

Answer:

88 days to complete 1 whole orbit so if it orbited 8 whole times around the sun it would be 704

Hope I helped

Answer:

88

Step-by-step explanation:

It's proximity to the Sun also means that it orbits the planet quite rapidly. To break it down, Mercury takes roughly 88 Earth days to complete a single orbit around the Sun.

Answer:

f = x * 5

I dont know how to explain it, but if it increases by 1 and adds 5, its multiplying by 5

The equation should be [tex]f = x\times 5[/tex]

The equation represents the statement where the values of two mathematical expressions should be equivalent to that presented by the sign = or equal sign.

Since  the input of a function f increases by 1, the output increases by 5

So, the equation should be

[tex]f = x\times 5[/tex]

Answer:

For every 5 students scoring in the 60s, there were 2 students scoring in the 70s.

Step-by-step explanation:

There are 40 scorers in the 60s and 16 scorers in the 70s. These are ratios, so the ratio between the 60s and the 70s would be 40/16. This fraction can be simplified down to 5/2. This means that for every 5 students scoring in the 60s, 2 scored in the 70s.
