Answer:

$100

Step-by-step explanation:

$500 x [tex](1-40-40[/tex]%[tex])\\[/tex]

= $500 x 20%

= $100

$ 100 is for Mia expected.

Mia is expected to sell her tablet for $100 because its value is projected to decrease for 40% per year.

Given the following data:

To find how much Mia is expected to sell her tablet:

First of all, we would determine the depreciation for the two year.

[tex]Two \;years = 0.4(2) = 0.8[/tex]

The depreciation cost:

[tex]500[/tex] × [tex]0.8 = 400[/tex]

Now, we would solve for the selling price by using the formula:

[tex]Selling\;price = Cost\;price - Depreciation\;cost\\\\Selling\;price = 500 - 400[/tex]

Selling price = $100

Therefore, Mia is expected to sell her tablet for $100 because its value is projected to decrease for 40% per year.

Answer:

Step-by-step explanation:

Given function:

Find its inverse, substitute x with y and f(x) with x:

Substitute y with f⁻¹(x):

Correct choice is B

Interchange x and y and solve for y

That's the inverse

Option B

f(x)=secxcscx

let secx=g(x)

let cscx=h(x)

therefore, using leibnitz rule,

f'(x)=g'(x)*h(x)+h'(x)*g(x)

    Since derivative of secx=secxtanx

    and derivative of cscx=-cscxcotx,

f'(x)=secxtanxcscx -cscxcotxsecx

     =1/cosx*sinx/cosx*1/sinx - 1/sinx*cosx/sinx*1/cosx

     =1/cos^2x-1/sin^2x

     =(sin^2x-cos^2x)/sin^2xcos^2x / Option1

The value of f'(x) is (sin^2x - cos^2x)/sin^2x cos^2x. Thus, option A is correct.

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

Given;

f(x) = secx cscx

let secx = g(x)

let cscx = h(x)

Using Leibnitz rule,

f'(x) = g'(x)h(x) + h'(x)g(x)

Since the derivative of secx = secx tanx

derivative of cscx = -cscx cotx,

f'(x) = secx tanx cscx - cscx cotx secx

f'(x) = 1/cosx sinx/cosx 1/sinx - 1/sinx cosx/sinx 1/cosx

f'(x)  =1/cos^2x - 1/sin^2x

f'(x) = (sin^2x - cos^2x)/sin^2x cos^2x

Thus, option A is correct.

Step-by-step explanation:

Standard form of equation of a parabola is [tex]y=ax^2+bx+c[/tex]

As it passes through points (−2,18), (0,2) and (4,42), each of these points satisfies the equation of parabola and hence

18=a⋅4+b⋅(−2)+c or 4a−2b+c=18 ........(A)

2=c ........(B)

and 42=a⋅16+b⋅4+c or 16a+4b+c=42 ........(C)

Now putting (B) in (A) and (C), we get

4a−2b=16 or 2a−b=8 and .........(1)

16a+4b=40 or 4a+b=10 .........(2)

Adding (1) and (2), we get 6a=18 or a=3

and hence b=2⋅3−8=−2

Hence equation of parabola is [tex]y=3x^2 -2x+2[/tex] and it appears as shown below

Step-by-step explanation:

Answer:

.94, 9/10, 88%, .78, and 8/11

Step-by-step explanation:

All % can be rewritten by moving the decimal 2 places to the left, (88% turns to .88)

Divide the fractions to get thier decimals

8/10 goes to .80

8/11 goes to .727272...

Now just put them in order

.7272, .78, .88, .90, .94 (Least to greatest)

.94, .90, .88, .78, .7272 (Greatest to least (What the problem wants))

Now convert them to the original form

.94, 9/10, 88%, .78, and 8/11

Answer:

1.31

Step-by-step explanation:

52.40÷40=1.31

I hope this helps:)

Jasmine's cost per liter of petrol is £1.31 when she pays £52.40 for 40 liters.

Total-Cost is divided by the quantity of units (liters) to find out how much each unit costs.

We know that : Cost of petrol is = £52.40,

The Quantity of petrol is = 40 liters,

The Cost per-liter can be calculated as = Total cost / Quantity of petrol

Substituting the values,

We get,

Cost per liter = £52.40/40,

Cost per liter = £1.31,

The concept of dividing the total cost by the quantity gives you a standard way to measure and compare costs on per-unit basis.

Therefore, the required cost per liter of petrol for Jasmine is £1.31.
