Answer:

Step-by-step explanation:

Note how this drawing  is symmetrical about a horizontal line drawn halfway between AB and CD and passing through the origin.

Line AB has been subdivided into two equal pieces of length 15, so the length of AB is twice 15, or 30.  Due to the symmetry shown, line CD has the same length:  30.

Answer:

type 2 in the first box,

13/4 in the second box, and

-9/8 in the third one

Step-by-step explanation:Notice that you are asked to write the following quadratic expression in vertex form, so you need to find the "x" value of the vertex, and then the "y" value of the vertex:

x_{vertex}= -b/2a

Which in our case is: -13/4

and the value of the y for the vertex is obtained using the functional expression when x equals -13/4:

f(-13/4)= -9/8

Then your expression for this quadratic should be:

f(x)=2\,(x+\frac{13}{4} )^2+(-\frac{9}{8})

Then type 2 in the first box, 13/4 in the second box, and -9/8 in the third one

A rectangular sand box has a length of 5 1/3 feet and a width of 3 3/4 feet. What is the perimeter in mixed number?
Vadim26 [7]

Answer: 18 1/6 feet

Step-by-step explanation:

From the question, we are informed that the rectangular sand box has a length of 5 1/3 feet and a width of 3 3/4 feet.

The perimeter would be calculated as:

= 2(length + width)

= 2( 5 1/3 + 3 3/4)

= 2( 5 4/12 + 3 9/12)

= 2( 8 13/12)

= 2 (9 1/12)

= 2 × 9 1/12

= 2 × 109/12

= 218/12

= 18 2/12

= 18 1/6 feet

ch4aika [34]
Standardized z score for the act result  =  (30 - 21.5) / 5.4  = 1.574

so for the sat ressult we have 1.574 = (X - 1498) / 316

X  = 316 * 1.574 + 1498  =  1995  answer
