Answer:

D.It is true because its domain of all real numbers greater than or equal to -7 and less than 2.

Step-by-step explanation:

We have to find that graph which represent a function whose domain of all real numbers :greater than or equal to -7 and less than 2.

A.Graph A does not represent that function because its domain of all real numbers greater than -2 and less than or equal to 7.It is not true.

B.Graph B does not represent that function because its domain of all real numbers greater than or equal to -4 and less than 1.

C.It is not true of all real numbers because its domain of all real numbers greater than or equal to -3 and less than 2.

D.It is true because its domain of all real numbers greater than or equal to -7 and less than 2.

Hence, option D is true.

The sum of two consecutive integers is -95. Find the integers. State the unknov-

kvasek [131]

Let the unknown consecutive integers be x, x+1

x+x+1=-95

2x+1=-95

2x=-95-1

2x=-96

x=-96/2

x=-48

x=-48

x=-48x+1=-48+1=-47

-48 and -47 are the two consecutive integers

two circles are externally tangent to each other. One circle has a diameter of 62 yards and the distance between the centers of

maksim [4K]

Answer:

108 yards

Step-by-step explanation:

Let circle A be the circle with the 62 yard diameter

Let circle B be the circle whose diameter we are trying to solve for.

Externally tangent circles are circles which touch each other and share a common external tangent.
Circle A has a tangent of 62 yards and thus a radius ( half the diameter) of 31 yards.
The distance between the centers of the 2 circles is 85 yards. If you subtract the radius ( distance from the center of the circle to its circumference) of circle A then we'll only be left with the radius of circle B.
85 - 31= 54 yards which is the radius of circle B
To get the diameter: 54 x 2 = 108 yards
