Is d=2t portional or non portional?

Mars2501 [29]

Answer:

a/(bxy) if b≠0, x≠0, y≠0, x≠y

Step-by-step explanation:

You have correctly simplified the expression. The conditions placed on both the original and simplified forms are that none of the denominator factors may be zero. The denominator factors are b, x, y, and (x-y).

$\dfrac{a}{bxy}\text{ if $b\ne0;$ $x\ne0;$ $y\ne0;$ $x\ne y$}$

Write a polynomial function with the given zeros x=-1,-1,6

damaskus [11]

Hello from MrBillDoesMath!

Answer:

x^3 - 6 x^2 - x + 6

Discussion:

The polynomial is

(x-1) (x - (-1)) (x-6) =

(x-1)(x+1)(x-6) = => as (x-1)(x+1) = x^2 - 1

(x^2-1)(x-6) =

x^2(x) - 6 x^2 - 1x + 6 =

x^3 - 6 x^2 - x + 6

Thank you,

MrB

What fraction is closest to .39. 1/3 or 2/5?

Maksim231197 [3]

2/5 would be closer

since 2/5 is 0.4
and 1/3 is 0.333...

You can draw a number line to see how 2/5 ( 0.4) is closest to 0.39

Answer:

For question 26 the answer is ( 9^210 )

For question 27 the answer is ( 24 )

Step-by-step explanation:

For question number 26: try on the scientific calculator the equation you have pictured it will give you a very long number beginning with 《 2459953978》

Then put the the 9^210 on the calculator and click ( =) if it didn't work try clicking S》D then you will get the same long number Count at least the first 6 numbers for assurance

For question number 27 :The volume of a right cone is given by 

 $v = \frac{1}{3} \pi \ \: {r}^{2} h$ 

 Here, you only know the value of one of the variables, V, so you'll need to use the information in the question to somehow write r and h in terms

If the cone is three times as wide at the base as it is tall, then call the diameter 3x and the height of the cone one-third of that, or x. The volume formula calls for the radius, which is half the diameter, or

 $\frac{3x}{2}$ 

Substitute these values into the formula and solve for x:

$384\pi = \frac{1}{3} \pi {( \frac{3}{2}\pi) }^{2} x \\ 384 = ( \frac{1}{3} )( \frac{9}{4} {x}^{2} )x \\ 384 = \frac{3}{4} {x}^{3 } \\ 512 = {x}^{3 } \\ \sqrt[3]{512} = x \\ 8 = x \\$

The question asks for the diameter of the base, which is 3x = 3(8) = 24.

Marc can run 2 miles in 16 minutes. At this rate, how long will it take Marc to run 5 miles?

skad [1K]

8= 1 minute so you do 8x5 because he runs 5 miles and your answer will be C=40 minutes. Hope this help :)
