Im not entirely sure what to do here can anyone explain it and tell me the answer

Talja [164]

We have $f(n)=f(n-1)+5.5$ . By entering 3 we get $f(3)=f(3-1)+5.5=f(2)+5.5$ because we enter again the function will apply further (will be recursive). $f(2)=f(2-1)+5.5+5.5=f(1)+5.5+5.5=3+5.5+5.5=\boxed{14}$ .

Hope this helps.

on a map with a scale 1:100,000 the distance between two cities is 12cm. what would be the distance between these two cities on

klio [65]

Part 1)

we have

the scale is $1:100,000$

the distance on a map is $12\ cm$

we know that

The scale is equal to the distance on a map divided by the real distance

Let

x------> distance on a map

y-------> real distance

S-------> scale

$S=\frac{x}{y}$

In this part we have

$S=\frac{1}{100,000}$

$x=12\ cm$

Find the value of y

$y=\frac{x}{S}$

Substitute the values

$y=\frac{12}{(1/100,000)}$

$y=1,200,000\ cm$

Convert to kilometers

$y=12\ Km$

Part 2)

In this part we have

$S=\frac{1}{300,000}$

$y=12\ km$

Find the value of x

$x=S*y$

Substitute the values

$x=(1/300,000)*12$

$x=0.00004 Km$

Convert to centimeters

$x=4\ cm$

therefore

the answer is

The distance is $4\ cm$

What's the answer? Plz explain.

Remark

Watch out for the -4<=x<=6 thing. It causes lot's of problems if you are not careful.

Solution.

The second best answer is A and if that restriction, -4<=x<=6, wasn't there, the answer would be A.

When y = - 4, the x value falls outside the restricted domain ( -4<=x<=6) we have been given. so B is not the answer.

When x = - 4 you have to read straight down to see what the y value is. It is - 2. So this is your answer. Only exactly what is the answer. They ask for the minimum value and that is a y value in this case.

So the answer is C <<<<< Answer.

When y = 1 , x = - 2 1/2. That is within the domain, but it is not the minimum value so D is wrong.
