Answer:
60
Step-by-step explanation:
Looking at case 1.
a * 10^5 + 2a * 10 ^4= 7200000
a * 10 * 10^4 + 2a *10 ^4 =7200000
[10a + 2a] * 10^4= 7200000
12a= 7200000/ 10000
12a= 720
a= 720/12 = 60
Looking at case 2,
a * 10^5 - a * 10^4 = 5400000
a * 10 * 10^4 - a *10^4 = 5400000
10a* 10^ 4 - a * 10^ 4 = 5400000
[10a- a] *10^4 = 5400000
9a = 5400000/10000
9a= 540
a =540/9
a= 60
The shaded set of numbers shown on the x-axis can be expressed in interval notation as [2, 6).
We are given a graph. The graph represents a downward parabola curve. A parabola is a plane curve that is mirror-symmetrical and roughly U-shaped in mathematics. It fits several seemingly disparate mathematical descriptions, all of which can be shown to define the same curves. There are two endpoints of the curve. The first endpoint with x-coordinate 2 is included in the graph of the curve. The second endpoint with x-coordinate 6 is not included in the graph of the curve. All the numbers between the endpoints are included in the graph of the curve. The set of numbers in the interval notation can be written as [2, 6).

Answer:
Step-by-step explanation:
You must assume that N is the center of the circle.
NTP is a right triangle.
NM is the radius
NT is also a radius
The area of the circle is 25pi
25 pi = pi r^2
r^2 = 25
r = 5
The right angle triangle can be solved by
PT^2 + NT^2 = (r + 4)^2
PT^2 + 25 = (5+4)^2
PT^2 + 25 = 81
PT^2 = 56
PT = sqrt(56)
PT = 7.48

Answer:
1/125 cm^3
Step-by-step explanation:
Volume of a cube = L^3
L is the side length of the cube
Given
L = 1/5 cm
Volume of the cube = (1/5)^3
Volume of the cube = 1/125
Hence the volume of the cube is 1/125 cm^3
