Answer:
it will take her 2 hours and 45 minutes
Let's solve your equation step-by-step.
(−
5
/8
)(x)=−160
Step 1: Simplify both sides of the equation.
−5
/8
x=−160
Step 2: Multiply both sides by 8/(-5).
(
8
/−5
)x(
−5
/8
x)=(
8/
−5
)*(−160)
x=256
Answer:
x=256
12.5%. there is a 1 in 8 chance that all three times it will land on heads.
Answer:
the answer is :the answer
Step-by-step explanation:
the answer is obvioulsy what ever the answer is,
You have shared the situation (problem), except for the directions: What are you supposed to do here? I can only make a educated guesses. See below:
Note that if <span>ax^2+bx+5=0 then it appears that c = 5 (a rational number).
Note that for simplicity's sake, we need to assume that the "two distinct zeros" are real numbers, not imaginary or complex numbers. If this is the case, then the discriminant, b^2 - 4(a)(c), must be positive. Since c = 5,
b^2 - 4(a)(5) > 0, or b^2 - 20a > 0.
Note that if the quadratic has two distinct zeros, which we'll call "d" and "e," then
(x-d) and (x-e) are factors of ax^2 + bx + 5 = 0, and that because of this fact,
- b plus sqrt( b^2 - 20a )
d = ------------------------------------
2a
and
</span> - b minus sqrt( b^2 - 20a )
e = ------------------------------------
2a
Some (or perhaps all) of these facts may help us find the values of "a" and "b." Before going into that, however, I'm asking you to share the rest of the problem statement. What, specificallyi, were you asked to do here?
