Answer is lots of god Which equation is the inverse of <em>y </em>= 100 – <em>x</em>2?




Answer:
C. The square root of a number, positive or negative, is always positive. However, the cube of a negative number is negative.
Step-by-step explanation:
Of the choices offered, the one shown above is the only one that remotely makes any sense. Its description of square roots is erroneous, however.
The square root of a number n is the solution to the equation ...
x² = n
The function f(x) = x² has a range that only includes non-negative numbers, so the square root of a negative number does not exist. (Your answer choice says it is positive. It is actually non-existent among real numbers.)
On the other hand, the cube root of a number n is the solution to the equation ...
x³ = n
Since f(x) = x³ has a range that includes all real numbers, the cube root of n exists for all real numbers. (It is negative for negative values of n.)

<em>Comment on answer wording</em>
The answer wording would be correct if the word "root" were left out.
They have to ride 3/8 more of the way there. 3/5 miles is 3/8 of the way there, so they need to ride 3/5 of a mile more.

Step-by-step explanation:
As we know,
Sum of a geometric sequence (S) = 
where,
a = first term of sequence,
r = the constant ratio,
n = number of terms in sequence.
So, according to the question,
a = 3,
r = 5,
n = 8.
by substituting the values in the above formula, we get;
