Answer:

1.length = 15, width = 12, height = 13

2. 13 × 12 × 15 = 2340

Step-by-step explanation:

3 ÷ 1/4 = 12

3 3/4 = 15/4

15/4 ÷ 1/4 = 15

3 1/4 ÷ 1/4 = 13

length = 15

width = 12

height = 13

13 × 12 × 15 = 2340

Select the correct answer. Segment KL is a diameter of circle Q. Circle Q is represented by the equation (x − 11)2 + (y + 15)2 =

m_a_m_a [10]

Answer:

2√7

Step-by-step explanation:

Mathematically, the equation of a circle can be represented by;

(x-h)^2 + (y-k)^2 = r^2

where (h,k) = center and r = radius

Applying this to the question, we can see that the length of the radius of the circle is √7

The diameter is always twice the radius

Thus, the diameter KL = 2 * √7 = 2√7

earnstyle [38]

Answer:

slop of e

y - intercept 2

x- intercept -0.735

Step-by-step explanation:

The value of e is 2.72 and this is the slope of the graph with a y intercept of:

$y=0+2$

$y=2$

and an x intercept of:

$0=ex+2$

$x=-2/e=-0.735$

The graph is attached with the x and y intercepts
