Find the least common multiple for 6(x+1)^3(x-4)^2 and 10(x+1)^8(x-4)^5

dolphi86 [110]

Answer:

30 $(x+1)^8 (x-4)^5$

Step-by-step explanation

In order to find the Least common multiple we write each of the factor only once from each of the expression and for the common expression we take their LCM as maximum of the exponent in all expressions

as here in the question exponent of (x+1) are 3 and 8 so we take exponent 8

likewise for (x-4) we shall take maximum of 2 and 5 which is 5

so our expression for Least common multiple will be

2X3X5 X $(x+1)^8 (x-4)^5$

30 $(x+1)^8 (x-4)^5$

Write an equation in slope-intercept form perpendicular to the given equation through the given point

Irina18 [472]

Answer:

y = (1/3)x - 4

Step-by-step explanation:

Any line perpendicular to the given equation y = -3x + 4 will have a slope which is the negative reciprocal of -3; that is, +1/3.

Start with the general slope-intercept form y = mx + b.

Insert the coordinates 6 and -2 into y = mx + b: -2 = (1/3)(6) + b, or

-2 = 2 + b. Thus, b = -4, and the desired equation is

y = (1/3)x - 4

A travel company sells holidays and wants to survey 500 customers stratified by country visited, complete the table.

OlgaM077 [116]

Answer:

$\left|\begin{array}{c|c|c|c|c||c}$Country Visited&$UK& $France& $Spain& $Italy &$Total\\&&&&&\\$Number of Customers &968& 248& 2042& 742& 4000\\&&&&&\\$Number of sample&121&31&255&93&500\end{array}\right|$

Step-by-step explanation:

$\left|\begin{array}{c|c|c|c|c||c}$Country Visited&$UK& $France& $Spain& $Italy &$Total\\$Number of Customers &968& 248& 2042& 742& 4000\\$Number of sample&&&&&&\end{array}\right|$

Since the company wants to survey 500 customers by the countries visited, the number of samples from each country will be proportional to the number of customers.

For UK, Number of Samples $=\dfrac{968}{4000}X500=121$

For France, Number of Samples $=\dfrac{248}{4000}X500=31$

For Spain, Number of Samples $=\dfrac{2042}{4000}X500\approx 255$

For Italy, Number of Samples $=\dfrac{742}{4000}X500\approx 93$

The completed table therefore is:
