To solve this problem, you would do 21 ÷ 25. After you have done this, you would have .84. You would then convert this to decimal form, which is 84%. The dog caught the frisbee in his mouth 84% of the time.
Answer:
0
Step-by-step explanation:
Answer:
x = -2/5 or 5
Step-by-step explanation:
We assume you want the values of x that make f(x) = 0. These are found using the zero product rule. That tells you a product is zero if and only if at least one factor is zero.
x -5 = 0 . . . . .assume the first factor is zero
x = 5 . . . . . . . add 5
__
5x +2 = 0 . . . assume the second factor is zero
5x = -2 . . . . . subtract 2
x = -2/5 . . . . divide by 5
__
smaller solution: x = -2/5
larger solution: x = 5
An exponential function can be expressed as:
y(x)=a^x
There is no restriction upon the value of a, so it can be a negative number.
So the statement is FALSE.
The best answer i do believe is b
