This table shows the input and output values for an exponential function f(x) .
Gre4nikov [31]
The correct answer is:  [B]:  "4 " .
______________________________________
Explanation: 
______________________________________
Refer to the table (provided within the actual question).

Note that the "inputs" ; or "x-values" ; are all listed in "chronological order" ; and are all "one (1) unit apart. and range from:  "x = -3"  to "x = 3" .

When "x = 0" ; the "output" ; or "f(x)"  is "1/4" . 
When "x = 1"  ; the "output" ; or "f(x)" is:  "1" .
_________________________________________________
So; the ratio of these two "outputs"  is:  "¼ : 1"  ; or, write as:
  " (¼) / 1 " ;   and note that:  " (¼) / 1 =  (¼) ÷ 1 = ¼.

However; note that: "1/4" ; or  "1:4" is NOT among the [answer choices given].

However, the ratio of the 2 (two) corresponding "outputs"; chronologically,
going from when "x = 1" ; to "x = 0" ;  is:  "1 : ¼" ; or;  write as:  "1 / (¼)" ; 

And note that:  "1 / (¼)"  =  " 1 ÷ (¼) " = 1 * (4/1) = 1 * 4 = "4" .

This corresponds to:  Answer choice: [B]:  "4<span>" .
</span>_________________________________________________
Let us further confirm that this answer is correct:
_________________________________________________
When x = 3;  the "output" is:  "16" .

When x = 2;  the "output" is:  "4" .

The ratio:  "16/4 = ?  4 ? " ;    →  Yes!
_________________________________________________
When x = 2;  the "output" is:  "4" .

When x = 1;   the "output" is:  "1" .

The ratio:  "4/1  = ?  4 ? " ;    →  Yes!
_________________________________________________
When x = 1;  the "output" is:  "1" .

When x = 0; the "output" is:  "(¼)" .

The ratio:  "1 / (¼)  = ?  4 ? " ;  

   →  "1 / (¼)"  =  " 1 ÷ (¼) " = 1 * (4/1) = 1 * 4 = "4" . YES!
________________________________________________
When  x = 0; the "output" is:  "(¼)" .

When  x = -1; the "output" is:  "(¹/₁₆)" .

The ratio:  "(¼) / (¹/₁₆)  = ?  4 " ? ;  
  
   →  "(¼) / (¹/₁₆) = "(¼) ÷ (¹/₁₆) " =  "(¼) * (¹⁶/₁) = (1*16) / (4*1) = 16/4 = "4" .  Yes!
________________________________________________________
When  x = -1; the "output" is:  "(¹/₁₆)" .

When  x = -2; the "output" is:  "(¹/₆₄)" .

The ratio:  "(¹/₁₆) / (¹/₆₄)  = ?  4 " ? ;  
  
   →  "(¹/₁₆) / (¹/₆₄)  = "(¹/₁₆) ÷ (¹/₆₄)" = "(¹/₁₆) * (⁶⁴/₁)" = (1*64) / (16*1) = 64/16 = "4" . Yes!
__________________________________________________________
When  x = -2; the "output" is:  "(¹/₆₄)" .

When  x = -3; the "output" is:  "(¹/₂₅₆)" ,

The ratio:  "(¹/₆₄)/(¹/₂₅₆)  = ?  4 " ? ;  
  
 → "(¹/₆₄) / (¹/₂₅₆)"  ;
 
       =   " (¹/₆₄) ÷ (¹/₂₅₆)" = " (¹/₆₄) * (²⁵⁶/₁) " = (1*256) / (64*1) = 256/164  =  "4 " . Yes!
__________________________________________________________
  → So; as calculated; the ratio is:  "4" ;  which is:
__________________________________________________________
  →  Answer choice:  [B]:  "4" .

Find the area of the figure. Use 3.14 for it.
Tcecarenko [31]

Answer:

<u>963.73 m²</u>

Step-by-step explanation:

<u>To Find :-</u>

Area of the figure

<u>Solving :-</u>

Area (figure) =  Area (triangle) + Area (semicircle)

= 1/2bh + 1/2πr²

= 1/2 (30 x 34 + 3.14 x 17 x 17)

= 1/2 (1020 + 289 x 3.14)

= 1/2 (1020 + 907.46)

= 1/2 (1927.46)

= <u>963.73 m²</u>

Given rectangular prism ABCD. Choose all of the terms that best describe each of the sets of lines or points. Points D, G and J
Yuki888 [10]

Answer:

Two points are collinear when they lie on the same line. Points are collinear but not lines. Rather when two lines lie on the same plane we say they are coplanar.

Hence, line AB and CD are NOT collinear, so they are noncollinear and they are coplanar.

Two or more lines are said to be intersecting, when the lines meet at some point, when lines are not intersecting they are said to be parallel.

Recall that one of the properties of a rectangle is that opposite sides are parallel.

Notice that line AB and CB are the opposite sides of the rectangle ABCD.

Thus, line AB and CD are not intersecting but are parallel.

Therefore, the terms that best describe lines AB and CD are  

parallel  

noncollinear  

coplanar
