What is the capacity of the cube in milliliters?
Murljashka [212]
The answer is:  [C]:  " 125 mL " .
________________________________
Explanation:
__________________________________________________
Volume of cube = 5 cm * 5 cm * 5 cm =  5³ cm³ ;

                          = (5 * 5 * 5) cm³  ;

                          =  125 cm³ .
______________________________________________________
              1 cm³ = 1 mL (exact conversion) ;  so, 125 cm³  =  125 mL  ;
                                                       which is:  Answer choice:  [C].

Please match each function formula with the corresponding transformation of the parent function y= -x^2-1
pishuonlain [190]

Answer:

The answer in the attached figure

Step-by-step explanation:

we have the parent function

y=-x^{2}-1

case 1) <u>Reflected across the x-axis</u>

we know that

The rule of the transformation is

(x,y)------> (x,-y)

so

y=-(-x^{2}-1)

y=x^{2}+1

case 2) <u>Reflected across the y-axis</u>

we know that

The rule of the transformation is

(x,y)------> (-x,y)

so

y=-(-x)^{2}-1

y=-x^{2}-1

case 3) Translated left by 1 unit

we know that

The rule of the transformation is

(x,y)------> (x-1,y)

so

y=-(x+1)^{2}-1

case 4) Translated right by 1 unit

we know that

The rule of the transformation is

(x,y)------> (x+1,y)

so

y=-(x-1)^{2}-1

case 5) Translated down by 1 unit

we know that

The rule of the transformation is

(x,y)------> (x,y-1)

so

y=-(x)^{2}-1-1

y=-(x)^{2}-2

case 6) Translated up by 1 unit

we know that

The rule of the transformation is

(x,y)------> (x,y+1)

so

y=-(x)^{2}-1+1

y=-(x)^{2}
