A and D would make the inequities true.
Finding the coordinates of the vertex is straightforward here, since we're given a good, clear diagram.
The vertex, in this case, is the lowest point of this graph. By counting from y-axis leftward, we see that the x-coordinate of the vertex is -4; by counting up to the y-axis, we see that the y-coordinate of the vertex is -4.
Thus, the vertex is located at (-4,-4).
Answer:
10 feet
Step-by-step explanation:
Given:
Volume of cube = 1000 cubic feet.
Question asked:
Length of an edge of the cube = ?
Solution:
Volume of cube = ![side^{3}](https://tex.z-dn.net/?f=side%5E%7B3%7D)
![1000=side^{3}](https://tex.z-dn.net/?f=1000%3Dside%5E%7B3%7D)
By taking cube root both side
![\sqrt[3]{1000} = side\\\sqrt[3]{10\times10\times10} = side](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B1000%7D%20%3D%20side%5C%5C%5Csqrt%5B3%5D%7B10%5Ctimes10%5Ctimes10%7D%20%3D%20side)
(took common)
Therefore, length of an edge of the cube is 10 feet.
X = 35
use the formula a^2 + b^2 = c^2 in order to find the hypotenuse, which is x.
21^2 + 28^2 = c^2
441 + 784 = c^2
1225 = c^2
35 = c
x = 35
