The difference is that in 4x you are multiplying 4 two times and in x4 you are multiplying 2 four times so 4x will be 4*4and x4 will be 2*2*2*2

Point B is collinear with A and C and partitions AC in a 3:4 ratio. B is located at (4,1) and C is located at (12,5). Find the c

Answer:

$A(-\frac{20}{3} ,-\frac{13}{3})$

Step-by-step explanation:

Point B partitions AC in a 3:4 ratio.

B is located at (4,1) and C is located at (12,5).

Let $(x_1,y_1)$ be the coordinates of A.

Then $(\frac{mx_1+nx_2}{m+n}, \frac{my_1+ny_2}{m+n})=(4,1)$

But m:n=3:4 implies m=3 and n=4 and $(x_2=12,y_2=5)$

$(\frac{3x_1+4*12}{3+4}, \frac{3y_1+4*5}{3+4})=(4,1)$

$(\frac{3x_1+48}{7}, \frac{3y_1+20}{7})=(4,1)$

$\frac{3x_1+48}{7}=4, \frac{3y_1+20}{7}=1$

$3x_1+48=28, 3y_1+20=7$

$3x_1=-20, 3y_1=-13$

$x_1=-\frac{20}{3} , y_1=-\frac{13}{3}$

A company uses paper cups shaped like cones for its water cooler. Each cup has a height of 10cm, and the base has a radius of 4.

prohojiy [21]

Answer: the answer is 150 :)

Step-by-step explanation: Volume of a cone is

V = 1/3 pi * r^2 *h

The volume of one cone is

pi = 3.14

r = d/2 = 6/2 =3

h=9

Substitute what we know

V = 1/3 * (3.14) * (3^2) * (9)

= 27* 3.14

= 84.78 cm^3

The water cooler has 12717 cm^3 water

Divide the water by the volume of the paper cup cone and we will know how many paper cup cones we can fill, assuming we fill them completely.

12717/ 84.78 = 150

We can fill 150 paper cup cones. have a great day!
