Answer:

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

Answer: To determine similarity, find the missing measure using the interior angle sum of a triangle. Then compare corresponding angles. If two pairs of angles are congruent, the triangles are similar because of the angle-angle criterion.

A tap is filling a 10-liters tank at the speed of 5 liters per minute.
SVETLANKA909090 [29]

Answer:

<em />

  • <em>It takes</em><u>     2.5 minutes   </u><em>to fill the tank.</em>

Explanation:

The net speed or net rate for filling the 10-liters tank is equal to the speed the tap is filling less the speed the water is leaking through the hole located at the bottom of the tank:

  • Net rate = rate of filling - rate of leaking
  • Net rate = 5 liters/minute - 1 liter/minute
  • Net rate = 4 liters/minute

Thus, consiedering the tank is empty at the beginning, the time is:

  • Time = Volume of the tank / net rate of filling
  • Time = 10 liters / (4liters/minute)
  • Time = 2.5 minutes ← answer

Find g(x), where g(x) is the translation 9 units up of f(x) = |x|.
geniusboy [140]

g(x) is the translation 9 units up of f(x) = |x|

g(x)=1|x-0|+9

Given :

The function f(x)=|x|

we need to translate f(x) , 9 units up to get g(x)

g(x) is the translation 9 units up of f(x)

when graph of f(x) is translated 9 units up , then we add 9 at the end

If f(x)=|x| is translated 'a' units up then its  becomes |x|+a

g(x) is the translation 9 units up of f(x) = |x|

So , g(x)=|x|+9

Write the answer in the given form a|x-h|+k

g(x)=1|x-0|+9
