Solution:
We have re-drawn the given diagram, as we can see the given rectangle is actually divided into two parts.
one is Large square and the other one is a smaller rectangle.
Now we will apply the Pythagoras theorem in the larger triangle which is inside the square.
So we can write

Now we will apply the Pythagoras theorem in the smaller triangle which is inside the smaller rectangle.
So we can write

The approximate sum of the lengths of the two sidewalks, shown as dotted lines
m
Hence the correct option is D
Given the ellipsoid

For the radius in the x-dirextion, y = z = 0, and we have

For the radius in the y-dirextion, x = z = 0, and we have

For the radius in the z-dirextion, x = y = 0, and we have

Thus, the radius of the ellipsoid is given by
Nine subtracted from negative seven would be sixteen.
Answer:
first blank = 10 (for table 1)
second blank = 30 (for table 2)
====================================================
Explanation:
You could use a calculator to determine the value of b, then compute b^x for that first box. But as the instructions state, we don't need to use one. Why is that? Because the tables provide enough information to fill in the blanks.
Table 1 shows x = 2.096 lead to some unknown y value. Meanwhile, table 2 has x = 10 lead to y = 2.096; note the 2.096 shows up again. The exponential and log functions are inverses of each other. They undo each other's operation. This is similar to how division undoes multiplication, and vice versa.
Going in reverse of table 2, we will conclude that 10 must go in the blank for table 1. Therefore, b^x = 10 when x = 2.096
------------
Similarly, we will have 30 in the blank for table 2. Table 1 shows x = 3.096 lead to y = 30. Table 2 is the reverse of that as it is the inverse.
Throughout either section, we didn't need to find the value of b.
