geniusboy [140]3 years ago
6 0

Step-by-step explanation:

The first number in the sequence is -6.

The second number is -3, which is 1/2 the first number.

The third number is -2, which is 2/3 the second number.

The fourth number is -3/2, which is 3/4 the third number.

The fifth number is -6/5, which is 4/5 the fourth number.

So the pattern is:

a_{n} = a_{n-1} \frac{n-1}{n}

How many grams is 3.3 mole of Mg(OH)2 ?
Brrunno [24]

Answer: m = 3.3 mol·58.326 mol = 192 g

Step-by-step explanation: molar mass of substance is

M= (24.31+ 2·1.008 + 2·16) g/mol = 58.326 g/ mol.

Amount of substance n = m/M and mass m = n·M

PLEASEE HELPP!!!!

y = - \frac{1}{4} x + \frac{15}{2}

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

y = 4x + 5 is in this form with slope m - 4

Given the slope of a line m, then the slope (m_{2}) of a line perpendicular to it is

m_{2} = - (1 / m ) = - \frac{1}{4}

y = - \frac{1}{4} x + c is the partial equation of the perpendicular line

to find c, substitute ( 2, 7 ) into the partial equation

7 = - \frac{1}{2} + c ⇒ c = \frac{15}{2}

y = - \frac{1}{4} x + \frac{15}{2} ← equation of perp. line

A boat traveled 240 miles downstream, then 240 miles back upstream. The trip downstream took 20 hours. The trip back upstream to
kotykmax [81]

Answer:

it takes longer for the boat to get back because it's moving against the current. to see how fast the boat is moving, you divide the amount of miles traveled, by how long it took.

240/20 = 12

in still water the boat travels it's 12 miles per hour

240/ 60 = 4

against the current, the boat travels 4 miles per hour

if you need to find the speed of the current, you need to find the resistance that's going against the boat making it slow down. you do that by doing        12 - 4 = 8 miles per hour is the speed of the current.

Step-by-step explanation:

I hope this helps :)
