To answer this item, we just have to substitute the given to the equation, where s is equal to 4 and v is equal to 80 ft/s.
4 = (80)t - 0.5(32 ft/s²)(t²)
The value of t from the equation generated above is equal to 4.94 s. Thus, the answer is approximately 5, letter D.
This would be true because it shows that p equals either a or b and it also shows that p equals a which is true because it is one of the independent choices.
Answer:
Hello! answer 9/1000
Step-by-step explanation:
All you have to do is multiply the probability of each then you will get your answer so...
6/20 × 4/20 × 3/20 = 9/1000 So thats your probability. Hope that helps!
Answer:
Step-by-step explanation:
Let the total amount be x
Then Ali got 1/8x With 7/8x left
Juma got 7/40x with 7/10x left
Musa, Khalid and Mustafa got 7/30x each
since 
7x=18000
the options that are polynomials are:
3.9x³-4.1x² + 7.3
x²y²-4x³+12y
4-x²
<h3>Which algebraic expressions are polynomials?</h3>
A polynomial is an expression of the form:
p(x) = aₙ*xⁿ + ...+ a₂*x² + a₁*x + a₀
Where all the exponents of the variable are whole numbers, and in this case we have only one variable x, but we could have any number of variables.
With that in mind, the options that are polynomials are:
3.9x³-4.1x² + 7.3
x²y²-4x³+12y
4-x²
These 3 expressions are polynomials.
