Please someone help me asap!

Serga [27]

Answer:

Option (D)

Step-by-step explanation:

Domain is a defined by the of x-values of the graph of a function.

Similarly, Range is defined by the y-values.

From the graph attached,

Domain of the graphed function: (-∞, ∞)

Range of the function: (0, ∞)

Therefore, domain is the set of all real numbers and range of the function is the set of all real numbers greater than zero.

Option (D) will be the correct option.

The owners of the Burger Emporium are looking for new supplier of onions for their famous hamburgers. It is important that the o

djverab [1.8K]

Answer:

Follows are the solution to this question:

Step-by-step explanation:

Let assume that X and Y reflect the diameters of onions by companies A and B.

$\to P(9$

$= P(-1.0833 < Z < -0.25)\\\\= P(Z < -0.25) - P(Z$

$\to P(9$

$= P(-1.7778 < Z < -0.6667)\\\\= 0.2148\\\\$

As a result, onions through company A are chosen and they're more likely to be accepted.

For what side length(s) is the area of an equilateral triangle equal to 30 cm?? Only enter the number, in centimeters, rounded t

xenn [34]

Answer: The sides length are 8.32 cm

Step-by-step explanation:

An equilateral triangle has all his sides of the same lenght, so we assume that the triangle has an L lenght in his sides.

The area of a triangle is $Area = \frac{base * height}{2}$ where the base is L, the Area is 30 and an unknown height.

To determine the height, we cut the triangle in half and take one side. By simetry, one side has a base of $\frac{L}{2}$ , a hypotenuse of L and a the unknown height.

Then we apply the <em>Pythagoras theorem</em>, this states that <em>in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides</em>, or, $hypotenuse = \sqrt{c^{2} + c^{2} }$ Where one c is $\frac{L}{2}$ and the other is the height.

Then we find one of the c of the equation wich will be the height.

$height = \sqrt{hypotenuse^{2}-base^{2} }$

$height = \sqrt{ L^{2} -\frac{L}{4} ^{2}}\\height = \sqrt{\frac{ 3L^{2}}{4} } \\\\height = \frac{\sqrt{3}L }{2}$

Finally, we use the triangle area mentioned before an find the value of L.

$30 = \frac{L*\frac{\sqrt{3}L }{2} }{2} \\\\L = \sqrt{\frac{120}{\sqrt{3} } } \\\\L = 8.32 cm$
