We're comparing 8.76 x 10^6 and 8.76 x 10^2
When multiplying numbers with same base but different powers, the result is that base and the powers added together.
Therefore:
8.76 x 10^6 can be written as: 8.76 x 10^2 x 10^4
Now, comparing the two numbers, we will find that 8.76 x 10^6 is 10^4 times greater than 8.76 x 10^2
Step-by-step explanation:
Since f(0) = f(5) = f(8) = 0, we have f(x) = Ax(x - 5)(x - 8), where A is a real constant.
We know that f(10) = 17.
=> A(10)(10 - 5)(10 - 8) = 17
=> A(10)(5)(2) = 17
=> 100A = 17, A = 0.17.
Hence the answer is f(x) = 0.17x(x - 5)(x - 8).
Let d=discriminant. The the rule is:
d>0, there are two real solutions
d=0, there is one real solution
d<0, there is no real solutions (but there are two imaginary solutions)
So if it is positive, there are two real solutions.
The answer is D hope this helps
