What is the simplified value of the exponential expression 27 1/3?<br> 1/3<br> 1/9<br> 3<br> 9

madreJ [45]

Answer:

Step-by-step explanation:

27^1/3

27 is cube root of 3

so it can also be written as (3)^3

∴ {(3)^3}^1/3

3 and 3 will get cancelled

so it will be 3^1

= 3

The coordinates of the endpoints of directed line sergeant ABC are A(-8,7) and C(7,-13). If AB:BC = 3:2 then the coordinates of

cestrela7 [59]

The correct answer is A) (1,-5)

Further explanation:

Given points are:

A(-8,7)=(x1,y1)

C(7,13)=(x2,y2)

IT is also given that

AB:BC=3:2

Which means that B divides the line segment in 3:2

Here,

m=3

n=2

To find the coordinates of B

$x_B=\frac{mx_2+nx_1}{m+n}\\ = \frac{(3)(7)+(2)(-8)}{3+2}\\=\frac{21-16}{5}\\=\frac{5}{5}\\=1\\y_B=\frac{my_2+ny_1}{m+n}\\=\frac{(3)(-13)+(2)(7)}{3+2}\\=\frac{-39+14}{5}\\=\frac{-25}{5}\\=-5$

The coordinates of point B are (1,-5)

The correct answer is A) (1,-5)

How do you solve -1/2 (-3/2 + 6x +1) -3x?

Delicious77 [7]

1/2 ( -3/2 + 6x + 1) - 3x

Simplify:
= 1/2 (-1/2 + 6x) - 3x

Apply distributive property:
= -1/4 + 3x -3 x

Simplify:
= -1/4

The cost of a ticket to an amusement park is $42 per person. for each group of up to eight people the cost per ticket decreases

zalisa [80]

This might not be correct but....
I’m going to use rounding,
42 x 2 = 84
84 divides by 3 = 28,
Which is near 30......So the number of people in the group is rounding to about 2 people.
