A rational number is a number that can be written as a ratio. That means it can be written as a fraction, in which both the numerator (the number on top) and the denominator (the number on the bottom) are whole numbers. The number 8 is a rational number because it can be written as the fraction 8/1.

11111nata11111 [884]

Answer:

Image below

Step-by-step explanation:

<em>Given: Side lengths of a right triangle 3,4 and 5 units. </em>

<em> To draw: A right triangle with the given side length. </em>

<em> Solution: </em>

<em> We know, in a right angle triangle hypotenuse is the longest side and satisfying Pythagoras theorem. </em>

<em> From the given side length, </em>

<em> Hypotenuse = 5 unit </em>

<em> We can take any of the base and perpendicular. </em>

<em> Let, Base = 3 unit </em>

<em> Perpendicular = 4 unit. </em>

<em> It a right-angle triangle with a hypotenuse 5 unit. </em>

<em> Now we draw a right angle triangle taking in the first 3 base and 4 perpendicular and second 3 perpendicular and 4 bases.</em>

STatiana [176]

Answer:

The answer is A

Step-by-step explanation:

The reason A is correct is because all of the other transformations change the size of the triangle, and A is the only answer that only reflects the image over the y axis without changing it, thus making it similar to the preimage

The function f(x) = −x2 + 28x − 192 models the hourly profit, in dollars, a shop makes for selling sodas, where x is the number
Rudik [331]

9514 1404 393

Answer:

  C- (14, 4); The vertex represents the maximum profit.

Step-by-step explanation:

The leading coefficient of the quadratic function is negative, so the graph opens downward, and the vertex represents a maximum.

The maximum value is at ...

  x = -b/(2a) = -28/(2(-1)) = 14

  f(14) = -14^2 +28(14) -192 = 4

The vertex is (14, 4). It represents the maximum profit.
