Answer:

Question 2:

If the size of bacteria is 2000 initially and doubles after every half hour

It means in the 1st 30 min its size is 2000

And in 60 min its

30min=2000

60min=?

60×2000=120000

120000÷30

=4000

And in 9hrs

1hr=60min

9hrs=?

60×9=540min

30min=2000

540min=?

2000×540

=1080000÷30

=360000

Which figure is the image produced by applying the composition t 0,3 r 0,90 to figure R?
Maksim231197 [3]

Answer:

Option A is correct

The only figure after composition of t_{0 , 3} (r_{0,90^{\circ}}) to figure R is Figure H

Step-by-step explanation:

From the given figure in R;

The coordinates in Figure R ;

(1 , -1) , (2, -2) ,(4, -2) ( 0, -4)

Composite function defined as when one function is substituted into another function.

To Apply the composition t_{0 , 3} (r_{0,90^{\circ}}) to figure R;

First apply the Reflection r_{0, 90^{\circ}} in Figure R;

The rule of reflection is given by:

(x,y) \rightarrow (-y,x)

By applying the rule of reflection in Figure R ,

then, the coordinates becomes;

(1 , -1) \rightarrow (1, 1)

(2 , -2) \rightarrow (2, 2)

(4 , -2) \rightarrow (2, 4)

(0, -4) \rightarrow (4, 0)

Now, apply the translation t_{0,3}

Translation : It is a type of transformation that moves each point in a figure the same distance in the same direction.

then,

the rule of translation is:

(x,y) \rightarrow (x+0,y+3)

Apply the rule of translation on coordinates (1,1) , (2,2),  (2,4) and (4,0)

then

(1 , 1) \rightarrow (1+0 1+3) =(1,4)

(2, 2) \rightarrow (2+0 2+3) =(2, 5)

(2, 4) \rightarrow (2+0 4+3) =(2 ,7) and

(4, 0) \rightarrow (4+0 0+3) =(4 ,3)

Then, the only figure after composition of t_{0 , 3} (r_{0,90^{\circ}}) to figure R is Figure H

What is the value of x in the equation 1/3x − 2/3 =− 18?
Klio2033 [76]

Answer:

x = -52

Step-by-step explanation:

\frac{1}{3}x-\frac{2}{3}=-18

Let us solve for x.

\frac{1}{3}x=-18+\frac{2}{3}

\frac{1}{3}x=-\frac{18*3}{1*3} +\frac{2}{3}

\frac{1}{3}x=-\frac{54}{3} +\frac{2}{3}

\frac{1}{3}x=\frac{-54+2}{3}

\frac{1}{3}x=\frac{-52}{3}

Use cross multiplication to find the value of x.

\frac{1x}{3}=\frac{-52}{3}

3*1x=3*-52

3x=-156

Divide both sides by 3.

x = - 52
