PLEASE HELP!!!!!!!!!!
yan [13]

115 = l \times 2.5 \times 5.75

\huge \mathrm{Answer࿐}

given :

\longmapsto volume = 115 yd³

Dimensions are :

  • 2\frac{1}{2} yd

  • 5\frac{3}{4} yd

  • L

We know,

\large \boxed{ \mathrm{volume = l \times b \times h}}

  • 115 =  2\frac{1}{2}  \times  5\frac{3}{4}  \times l

  • l \times  \dfrac{5}{2}  \times  \dfrac{23}{4}  = 115

  • l  \times  \dfrac{115}{8} = 115

  • l = 115 \times  \dfrac{8}{115}

  • l = 8 \: yd

Therefore Length of the prism is 8 yards.

The median is 28; 16,24,x,48
Nookie1986 [14]
x = 32 

To find the media, you take the middle number. If there is no discrete middle number, take the sum of the two closest to the middle and divide by 2. 

(24 + x)/2 = 28

Multiply by 2 on both sides to get:

24 + x = 56

Subtract 24 from both sides to isolate the variable:

x = 56 - 24
x = 32

Is knowing the coordinates of the vertex of a parabola enough to determine the domain and range?
puteri [66]

The <em>correct answers</em> are:


C) No: we would need to know if the vertex is a minimum or a maximum; and

C)( 0.25, 5.875).


Explanation:


The domain of any quadratic function is all real numbers.


The range, however, would depend on whether the quadratic was open upward or downward. If the vertex is a maximum, then the quadratic opens down and the range is all values of y less than or equal to the y-coordinate of the vertex.


If the vertex is a minimum, then the quadratic opens up and the range is all values of y greater than or equal to the y-coordinate of the vertex.


There is no way to identify from the coordinates of the vertex whether it is a maximum or a minimum, so we cannot tell what the range is.


The graph of the quadratic function is shown in the attachment. Tracing it, the vertex is at approximately (0.25, 0.5875).
