Answer:

See below

Step-by-step explanation:

20% loss a year with initial value of £6000 can be shown as function:

V(t) = 6000*0.8^t

V(t) - is the value after t years

a) t = 1 year

V(1) = 6000*0.8 = £4800

b) t = 3 years

V(3) = 6000*0.8^3 = £3072

c) t = 8 years

V(8) = 6000*0.8^8 = £1006.63

Ted has $3.90. He has only dimes and quarters. He has 27 coins altogether. How many of each does he have

mestny [16]

Answer: 8 quarters 19 dimes

Step-by-step explanation:

we already know 8+19=27, if 4 quarters equals a dollar then you use 4 quarters each to create 2 dollars.

then, use 10 dimes to create another dollar summing it up to $3. now all we have to do is make 90 cents, and we've already used 18 coins.

if we used another 9 dimes, that would equal 90 cents.

in conclusion, 4+4= 8

8+10= 18

18+9= 27, and having $3.90

Find the quotient. 12a^3p^4 ÷ -2a^2p

777dan777 [17]

Answer:

-(6ap³)

Step-by-step explanation:

We have to find the quotients of

$\frac{12a^{3}p^{4}}{-2a^{2}p}$

We take the common 2a² p from the numerator

= $\frac{(6ap^{3}(2a^{2}p))}{(-2a^{2}p)}$

= -(6ap³)

Therefore, the quotient after division will be -(6ap³)

Given r(x) = startfraction 11 over (x minus 4) squared endfraction , which represents a domain restriction on r(x) and the corre

Dmitry_Shevchenko [17]

The domain and inverse of the function

$r(x) = \frac{11}{(x - 4)^2}$ is

Domain = $\mathbb{R} - \{4\}$ ,

$r^{-1}(x) = \pm \sqrt{\frac{11}{x}} + 4$

What is a function?

A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.

There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.

The given function is

$r(x) = \frac{11}{(x - 4)^2}$

r(x) is not defined if x - 4 = 0

r(x) is not defined for x = 4

Domain = $\mathbb{R} - \{4\}$ ,

Where $\mathbb{R}$ is the set of all real number

Let r(x) = y

$\frac{11}{(x-4)^2} = y\\(x - 4)^2 = \frac{11}{y}\\x - 4 = \pm \sqrt{\frac{11}{y}}\\x = \pm\sqrt{\frac{11}{y}} +4$

$r^{-1}(x) = \pm \sqrt{\frac{11}{x}} + 4$
