Counter clockwise means it goes backwards so -90°

After the 90° counter clockwise rotation the coordinates are (4,-3)

Answer:

The co-ordinates of the image of P is (-4,3).

Step-by-step explanation:

We are given the point P =(-3,-4).

Ir is rotated 90° clockwise about the origin.

We know,

Rotation of 90° clockwise about the origin changes the co-ordinate (x,y) to (y,-x).

So, the co-ordinate of the image of P =(-3,-4) will be P' = (-4,3).

Thus, the co-ordinates of the image of P is (-4,3).

Coach velez took the basketball team out for ice cream sundaes.He bought 8 sundaes at $5.35 each.He left a 15% tip.How much did
joja [24]
To find the value of Coach Velez's total bill, first we must figure out how much the total of all of the ice cream sundaes were.

To do this, we must multiply the number of sundaes (8) by the cost of each sundae ($5.35).

8 * 5.35 = $42.80

However, Coach Velez also left a tip of 15%.  To find out how much Coach Velez tipped, we have to multiply his regular bill ($42.80) times the amount he is tipping (15% or 0.15)

$42.80 * 0.15 = $6.42

Finally, we just have to add the bill ($42.80) and the tip ($6.42) together to find Coach Velez's total amount.

$42.80 + $6.42 = $49.22

Coach Velez spent $49.22 in all.

A point moves along a straight path. The function f ( t ) = log 2 ( t ) determines the distance (in meters) the point has travel
Marina CMI [18]

Answer:

a) 4.392317 mt

b) 9 seconds

c) \large f^{-1}(d)=2^d\;sec.

Step-by-step explanation:

We have

\large f(t)=log_2(t)

where t is given in seconds and t in meters.

<em>a)How far has the point traveled 21 seconds after it started moving?</em>

By replacing t=21 in our equation we get

\large f(21)=log_2(21)=4.392317 \;mt

<em>b)If the point has traveled 3.16993 meters, how many seconds have elapsed since it started moving?</em>

We need to find a t such that f(t) =3.16993.  

This can be accomplished by using the definition of log_2

\large f(t)=3.16993\rightarrow log_2(t)=3.16993\rightarrow t=2^{3.16993}=9\;sec.

<em>c)Write a function f^{-1} that determines the number of seconds that have elapsed since the particle started moving in terms of the distance (in meters) the particle has traveled.</em>

f^{-1} is given by the definition of log

\large f^{-1}(d)=2^d\;sec.
