F(x)=1/x−4−6f(x)= x−41 −6. Find the inverse of f(x) and its domain.

Maslowich

Answer:

C

Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift left of a units

• If a < 0 then a shift right of a units

The graph of g(x) is the graph of f(x) shifted 6 units left , then

g(x) = f(x + 6) → C

In the summer term sal wlks to school starting soon after 7 am when the hour hand is at angle of 110 degrees to the minute hand.

Solnce55 [7]

Answer:

She walked for 46 minutes

Step-by-step explanation:

Given

When she leaves home

$h = 7am$

$\theta_1 = 110^o$

When she arrives at school

$H = 8am$

$\theta_2 = 110^o$

Required

Time to walk to school

First, we convert $\theta_1 = 110^o$ to minutes:

$\theta_1 = \frac{110}{6}$

$\theta_1 = 18.33$

$\theta_1 = 18$ --- approximated

From the question, we understand that she left home past 7.

This means that the difference between the hour hand (at 7) and the minutes hand is 18 minutes.

Also, the minute hand is between 0 and 30 minutes

Subtract 18 minutes from 30 minutes;

$Mins = 30-18=12$

She left home at 7:12am

Similarly;

$\theta_2 = \theta_1 = 18\ mins$

From the question, we understand that she arrived before 8.

This means that the difference between the hour hand (at 8) and the minutes hand is 18 minutes

Also, the minute hand is between 30 and 60 minutes mark.

At the 8hour hand, the minutes is 40

Add 18 minutes from 40 minutes;

$Mins = 40 + 18 = 58$

She arrived at 7:58am

The difference (d) is:

$d =7:58am - 7:12am$

$d =46$

A grade has 81 girls and 72 boys. The grade is spilt into groups that have the same ratio of boys to girls as the whole grade. H

MariettaO [177]

There are 81 girls to every 72 boys in total, which can be represented by 81/72, which put into decimal form, is 1.125. If you then take the number of boys in the group, 16, and multiply it by this number (because the problem states that the ratio is constant) you can find the number of girls in the group.

16*1.125=18

So there are 18 girls in a group with 16 boys.
