Answer:

64,000km/2hrs ×5/18(yo convert km/h to m/s we mutiply the no. with 5/18 whereas to change it to m/s we multiply it by18/5)

tgerfore32,000×5/18

=80000/9

=8888.88889

The equation of the line that contains the points (-8, 1) and (0, -5) is
posledela

Answer:

y = -3/4x -5 (G)

Step-by-step explanation:

Find the slope by using the slope formula. (It's hard to format here so look it up)

Basically, it is y2 - y1/x2 - x1

-5 - 1/ 0 + 8

-6/8 = -3/4

The slope is -3/4.

Plug in for y = mx + b

y (y coordinate) = -5

x (x coordinate) = 0

slope (m) = -3/4

-5 = -3/4(0) + b

-5 = 0 + b

b = -5

y = -3/4x -5

Name the possible rational roots for the function using the Rational Root Theorem.
blondinia [14]

Answer:

\pm 1,\pm 3,\pm 5,\pm 15,\pm \frac{1}{3},\pm \frac{5}{3}

Step-by-step explanation:

Given:

The function is given as:

f(x)= 3x^{3}-19x^{2} +23x-15

The possible rational roots for a function f(x) = a_{n}x^{n}-a_{n-1}x^{n-1} +a_{n-2}x^{n-2}+....a_{1}x+a_{0} using the Rational Root Theorem is given as:

\pm (\frac{\textrm{Factors of }a_{0}}{\textrm{Factors of } a_{n}}})

Here, a_{0}=-15,a_{n}=3

Factors of -15 = \pm1,\pm3,\pm5,\pm15

Factors of 3 = \pm1,\pm3

Now, possible roots are given as:

\pm (\frac{\textrm{Factors of }a_{0}}{\textrm{Factors of } a_{n}}})\\\\=\pm(\frac{\pm1,\pm3,\pm5,\pm15}{\pm1,\pm3})\\\\=\pm\frac{1}{1},\pm\frac{1}{3},\pm\frac{3}{1},\pm\frac{3}{3},\pm\frac{5}{1},\pm\frac{5}{3},\pm\frac{15}{1},\pm\frac{15}{3}\\\\=\pm1,\pm\frac{1}{3},\pm3,\pm1,\pm5,\pm\frac{5}{3},\pm15,\pm5\\\\=\pm1,\pm \frac{1}{3},\pm3, \pm 5, \pm \frac{5}{3},\pm15

Therefore, option 1 is correct.

Tom starts lawn mowing business before he can begin he purchases a new lawnmower each weekend he mows the same number of lawns a
Anastasy [175]
To be able to give the answer to this item, we are to represent first with any variables the amount he earns each weekend for mowing the same field. Also, we represent the number of weeks he had worked by the variable y. The total amount of money he will have after working for y weeks is,
 
                           T = xy

Since, we are not given with any other information of the other expenses that have to be paid  then we can say that if T is already equal to the price of the new lawnmower then, Tom will be able to purchase it and begin his lawn mowing business in due time.
