Answer:

Step-by-step explanation:

Let's remember that the first number to the right of the decimal point is the "tenth".

The first number to the left of the decimal point is the "ones"

The second number to the left of the decimal point is the "tens"

In this problem we have the number 28.6 and we need to round it to the nearest ones.

To round to the nearest ones, we have to observe the tenths: in this case the tenth is a 6, this means that we will round it up (6,7,8 and 9 round up, and 1,2,3,4 and 5 round down).

Therefore, since the digit that corresponds to the ones is the 8, we will round it up to 9 and we obtain the number 29.

Since the numbers 5 and above round up, it rounds to 29.

Find the inverse of f(x) = -4x - 12

olga2289 [7]

Answer:

$\implies f^{-1}(x) =-\dfrac{x}{4}-3$

Step-by-step explanation:

Given :-

f(x) = -4x-12

And we need to find out the Inverse of the function . Let us assume that f(x) = y . Now , firstly replace x with y and vice versa.

Function :-

$\implies f(x) = -4x - 12 \\\\\implies y = -4x-12$

Interchanging x and y :-

$\implies x = -4y - 12$

Solve out for y :-

$\implies x = -4y - 12 \\\\\implies -4y = x +12 \\\\\implies y =\dfrac{x+12}{-4}\\\\\implies y =-\dfrac{x}{4}-3$

Replace y with f-¹(x) :-

$\implies f^{-1}(x) =-\dfrac{x}{4}-3$

Hence the inverse of the function is -x/4-3 .

we know that

1) scale factor is equal to $\frac{1}{10}$

2) The ratio of the perimeters of the triangles is equal to the ratio of the measures of the sides

3) the longest side of ∆ABC=[scale factor]*the longest side of ∆DEF

the longest side of ∆ABC= $\frac{1}{10}*40$

the longest side of ∆ABC= $4$ units

the answer part a) is

the longest side of ∆ABC is $4$ units

Part b)

The ratio of the area of ∆ABC to the area of ∆DEF is equal to the scale factor squared

$[scale factor]^{2} =(\frac{1}{10})^{2} \\ \\ =\frac{1}{100} \\ \\ =0.01$

therefore

the answer part b) is

The ratio of the area of ∆ABC to the area of ∆DEF is $\frac{1}{100}$
