First, find your total sales. You do this by adding all the sales together, 2030+1540+1800=5370. Now, for each person, divide their sales by total sales.Lola) 2030/5370=203/537≈0.378=37.8%Ahmed) 1540/5370=154/537≈0.287=28.7%Tommy) 1800/5370=180/537=60/179≈0.335=33.5%

FrozenT [24]

Answer:

1. 80 yd

2. 10 and 10 of the other side

3. yes

Step-by-step explanation:

1. As we were asked to stay 240 feet away, and we will be on a soccer field and it has marked distances in yards we just have to pass our feet to yards.

1 ft = 1/3 yd

240 ft = 240/3 yd

240 ft = 80 yd

2. one would have to stand in yard 10 and the other in yard 10 but from the other side of the field

50-10 = 40

40 + 40 = 80 yd

if they are diagonally the distance will be greater than 80, since the yards are parallel, because only the distance would remain only if they are on the same height

WILL MARK BRAINIEST!!! Segment AC has two endpoints; (-2,5) and (2,-5). What are the coordinates of point B on segment AC such t

svet-max [94.6K]

Answer:

$(\frac{4}{3},-\frac{10}{3})$

Step-by-step explanation:

If the extreme ends of a line segment AC are A $(x_1,y_1)$ and C $(x_2,y_2)$ .

If a point B(x, y) divides the segment in the ratio of m : n

Then the coordinates of the point B are,

x = $\frac{mx_2+nx_1}{m+n}$

y = $\frac{my_2+ny_1}{m+n}$

If the ends of AC are A(-2, 5) and C(2, -5) and a point B divides it in the ratio of m : n = 5 : 1

Therefore, coordinates of this point will be,

x = $\frac{5\times (2)+1(-2)}{5+1}$

= $\frac{10-2}{5+1}$

= $\frac{8}{6}$

= $\frac{4}{3}$

y = $\frac{5\times (-5)+1(5)}{5+1}$

= $\frac{-25+5}{6}$

= $-\frac{20}{6}$

= $-\frac{10}{3}$

Therefore, coordinates of the point B are $(\frac{4}{3},-\frac{10}{3})$ .

Write a rule for g that represents the indicated transformations of the graph of f.

finlep [7]

The rule of g(x) is g(x) = 2 $(x-4)^{4}$ + 4(x - 4) + 12

Step-by-step explanation:

Let us revise some transformation

If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)
If k > 1, the graph of y = k•f(x) is the graph of f(x) vertically stretched by multiplying each of its y-coordinates by k

∵ f(x) = $x^{4}$ + 2x + 6

∵ The graph of f(x) is stretched vertically by a factor of 2

- That means the y-coordinate of each point on the graph is multiplied

by 2, then y = 2.f(x) as the 2nd rule above

∴ y = 2[ $x^{4}$ + 2x + 6]

∴ y = 2 $x^{4}$ + 4x + 12

∵ The graph of 2.f(x) is translated 4 units to the right

- That means substitute every x by (x - 4) as the 1st rule above

∴ g(x) = 2 $(x-4)^{4}$ + 4(x - 4) + 12

The rule of g(x) is g(x) = 2 $(x-4)^{4}$ + 4(x - 4) + 12
