1 answer:

7 0

Right now, x is only equal to two. Square both sides, and x^2 = 4. For some reason, if you want to take the square root of both sides, and you get x= +/- 2, ...

In the coordinate plane, what is the length of the line segment that connects points at (5,4) and (-3,-1)

baherus [9]

Answer:

9.434 units

Step-by-step explanation:

Given data

points (5,4) and (-3,-1)

x1= 5

y1= 4

x2= -3

y2= -1

The expression for the distance between two points is

d=√((x_2-x_1)²+(y_2-y_1)²)

substitute

d=√((-3-5)²+(-1-4)²)

d=√((-8)²+(-5)²)

d=√64+25

d=√89

d=9.4339

d= 9.434 units

Hence the distance between the points is 9.434 units

The mass of a carbon atom is 1.994 × 10-23 grams. The mass of a hydrogen atom is 1.67 × 10-24 grams. What is the difference of t

Bezzdna [24]

Solving:
$1.994*10^{-23}\:-\:1.67*10^{-24} = 
$
$(1.994 - 0.167 )*10^{-23}$
$\boxed{\boxed{1.827*10^{-23}\:grams}}\end{array}}\qquad\quad\checkmark$

Volume of A = 1728

volume of B = 729

(1728 / 729) = (a / b)^3 (a = width of A, b = width of B)
a / b = cube root (1728 / 729) = 4/3 b = 10 (given)
a / 10 = 4/3 
a = 40/3 = 13.33333
so width of A is 13.33m
