A flying disc has 4 3/4 inch radius. What is its circumference to the nearest inch?
Anastasy [175]

To find the circumference, multiply the radius by 2, then multiply by PI.

4 3/4 x 2 = 9 1/2

9 1/2 x PI = 9 1/2 x 3.14 =  29.83

Find all values of x that are NOT in the domain of h.
Firlakuza [10]

Answer:

if x=-1 then its is NOT in the domain of h.

Step-by-step explanation:

Domain is the set of values for which the function is defined.

we are given the function

h(x) = x + 1 / x^2 + 2x + 1

h(x) = x+1 /x^2+x+x+1

h(x) = x+1/x(x+1)+1(x+1)

h(x) = x+1/(x+1)(x+1)

h(x) = x+1/(x+1)^2

So, the function h(x) is defined when x ≠ -1

Its is not defined when x=-1

So, if x=-1 then its is NOT in the domain of h.

Based only on the information given in the diagram, which congruence
vovangra [49]

Answer:

Step-by-step explanation:On the given diagram you see two right triangles with equal hypotenuses and pair of equal angles.  

Based only on the information given in the diagram you can conclude that triangles are congruent by HA theorem (the HA theorem states that "if the hypotenuse and an acute angle of one right triangle are congruent to the hypotenuse and an acute angle of another right triangle, then the two triangles are congruent").

Also you can conclude that triangles are congruent by AAS Postulate (the AAS Postulate states that "if two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent").
