Answer:
C
Step-by-step explanation:
The volume of a rectangular prism is given by:
[tex]V=\ell wh[/tex]
The width is x, the length is x²y, and the height is y². Thus, the volume is:
[tex]V=(x)(x^2y)(y^2)[/tex]
Multiply:
[tex]V=x^3 y^3[/tex]
Our answer is C.
A

Harvey is studying the polynomial f(x) = (2x - 3)(x - 4)(x2 + 3) and determines that the polynomial has four real roots. Is
Harvey's statement CORRECT?
A. No, the polynomial f(x) has 2 real roots and 2 complex roots when solved.
O B. Yes, the polynomial f(x) has 4 x-intercepts so the function has 4 real roots.
C. Yes, the polynomial f(x) has a degree of 4 so the function has 4 real roots.
OD. No, the polynomial f(x) has 3 real roots because there are 3 factors.
Answer:
It is A, I highly suggest you should read my explanation.
Step-by-step explanation:
(2x - 3)(x - 4)(x^2 + 3)
Exponent of 2x = 1
Exponent of x = 1
Exponent of x^2 = 2
Add them all together to get the degree. 1 + 1 + 2 = 4
Now we can tell that the polynomial can have 1,2,3,4, or no roots at all. The max number roots it can have is 4
To see the number of roots it has, we have to set each part equal to 0
2x - 3 = 0
Add 3 to both sides
2x - 3 + 3 = 0 + 3
2x = 3
Divide both sides by 2
2x/2 = 3/2
x = 3/2 or 1.5
Next,
x - 4 = 0
Add four to both sides
x - 4 + 4 = 0 + 4
x = 4
Then,
x^2 + 3 = 0
Subtract 3 from both sides
x^2 + 3 - 3 = 0 - 3
x^2 = -3
Find the square root of both sides
sqrt(x^2) = sqrt(-3)
x = i*sqrt(3), -i*sqrt(3)
Those are imaginary numbers, therefore there are not real.
The real roots are x = 3/2, 4
Harvey stated that this equation has four real roots. We can cross options B and C out since they stated he was correct.
It is not D because finding a square root of a number gives two answers; the positive and negative version, so it will have two solutions. There were only two real roots and the other two roots are complex roots.
That leaves us to option A, which states that there are 2 real and 2 complex roots. It is correct

Describe and correct the error in solving the following rational equation , plz help!!!!!
First of all, x cannot ever equal -1 because if it does then in the original equation you'd be dividing by 0, which is not possible. anything divided by 0 is undefined.
I think the error was in the second step: x(x+1) = 2(x+1) because they didn't need to go from the first step to there. I'm assuming they multiplied both sides of the equation with (x+1) to get rid of the fraction, but since both sides have (x+1) as the denominator the (x+1) would've cancelled out instead of multiplying with the numerator.
Correction:
[tex]\frac{x}{x+1} = \frac{2}{x+1}\\(\frac{x+1}{1}) (\frac{x}{x+1}) = (\frac{2}{x+1})(\frac{x+1}{1}) \\x = 2[/tex]
as u can see, in the second step of this correction, the (x+1)s on both sides cancel out so only the numerators remain.
Hope this helps!

5. What is the value of x?
Answer:
5[tex]\sqrt{3}[/tex]
Step-by-step explanation:
in a 30-60-90 triangle the ratio of sides, respectively, is 1 : [tex]\sqrt{3}[/tex] : 2
you can set up a proportion like this to solve for 'x':
[tex]\sqrt{3}[/tex] / 1 = 15 / x
cross-multiply:
[tex]\sqrt{3}[/tex]x = 15
x = 15/[tex]\sqrt{3}[/tex]
rationalize the denominator by multiply top and bottom by [tex]\sqrt{3}[/tex]
you get 15[tex]\sqrt{3}[/tex] ÷ 3 which is 5[tex]\sqrt{3}[/tex]

Mr. Hayes has 11 straw bundles to use forr bedding in his horse stalls. What is the greatest number of stalls he can fill if each stall holds exactly 4 bundles
Answer:
2 stalls
Step-by-step explanation:
Mr. Hayes has 11 straw bundles to use forr bedding in his horse stalls. What is the greatest number of stalls he can fill if each stall holds exactly 4 bundles
1 stall = 4 bundles
4 bundles = 1 stall
11 bundles = x
Cross Multiply
4x = 11
x = 11/4
x = 2 3/4 stalls
The greatest number of stalls he can build is 2 stalls

What is 45 minutes before 7 o'clock
Answer: Its 6:15
Step-by-step explanation:
Its simple math. 7:00 subtract 45minutes, knowing that 60minutes is an hour and that its the 7 hour from the 6 hour. Gets you 6:15.
Yep.
The 45 minutes before 7 o'clock will be 6.15 AM/PM.
What is the time?the indefinite continued progress of existence and events in the past, present, and future regarded as a whole.
In other words, time is something which measure by motion and it is given by einstein that time depends upon motion.
For example time = distance/velocity so it means time also depends on velocity.
In the given question, we know that in
1 hour = 60 minutes
45 minutes before of 7 o'clock = 60 - 45 = 15 minutes after 6 o'clock hence 6.15 minutes will be correct answer.
