Select the equation that is the inverse of the given function.
X-3
f(x) =
5
f-1(x) = 5x +15
O f-1(x) = 5x + 3
f-1(x) = 3x - 5
o 4-16x) = x
Answer:
B. f⁻¹(x) = 5x + 3Step-by-step explanation:
Given function:
f(x) = (x - 3)/5Find its inverse, substitute x with y and f(x) with x:
x = (y - 3)/55x = y - 3y = 5x + 3Substitute y with f⁻¹(x):
f⁻¹(x) = 5x + 3Correct choice is B
Interchange x and y and solve for y
x=y-3/55x=y-3y=5x+3That's the inverse
Option B
Jasmine pays £52.40 for 40 litres of petrol. What is the cost per litre?
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.

What is f '(x) for f(x) = secxcscx?
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.
What are trigonometric identities?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.

Mia buys a tablet in $500. and plans to sell it in 2 years. the tablet value is projected to decrease for 40% per year. for how much Mia is expected to sell her tablet?
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:
Cost of tablet = $500Time = 2 yearsDepreciation rate = 40% per year = 0.4To 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.

So, the sum of the 3 angles in a triangle is 180.
What you would do is:
180= 73+6x-4+7x+7.
Then, you add the common coefficients:
180=76+13x
Then you subtract:
104=13x
Then you divide:
x=8.
Then substitute the x value into the A value to get 44, meaning that C is the correct answer.

1. What is the equation, in standard form, of a parabola that contains the following points? (1 point)
(-2, 18), (0.2). (4, 42)
Oy=-222 - 2x - 3
Oy=-3x2 + 2x - 2
Oy = 3x2 - 2x + 2
Oy=-2x2 + 3x + 2
Answer:
y=3x2−2x+2
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
