Answer:

11.1m/s to the right

Step-by-step explanation:

Momentum before = momentum after

m₁u₁+m₂u₂=(m₁+m₂)v

1000(20)+800(0)=(1000+800)v

20000 = 1800 v

v= 11.1m/s to the right (to the right because the number is positive)

A bank charges $25/month plus $0.25/transaction for use of an ATM card. What is true about the function for this problem?
Elan Coil [88]

Option A, C, D

The equation is y = 25 + 0.25x

The slope is 0.25 and y intercept is 25

<em><u>Solution:</u></em>

Given that, bank charges $25/month plus $0.25/transaction for use of an ATM card

Therefore,

Initial charge = $ 25

Let "x" be the number of transactions

Given that the charge is $ 0.25 per transaction

<u><em>Thus, we frame a equation as:</em></u>

total charge = Initial charge + 0.25(number of transactions)

Let "y" be the total charge for month

y = 25 + 0.25x

The equation is y = 25 + 0.25x

Thus option C is correct

<em><u>The equation of line in slope intercept form is given as:</u></em>

y = mx + c

Where, "m" is the slope of line and "c" is the y intercept

On comapring y = 25 + 0.25x with y = mx + c, we get

m = 0.25 and c = 25

Thus slope is 0.25 and y intercept is 25

Thus option A and option D are correct

-x + y = 5
diamong [38]

Answer:

A. -(5y+2) + y = 5

Step-by-step explanation:

Solving the above Equation given to us in the Question,

-x + y = 5...... Equation 1

x - 5y = 2....... Equation 2

Step 1

We make x subject of the formula in Equation 2

---> x= 5y + 2

Step 2

This would be to substitute 5y + 2 for x in Equation 1

-x + y = 5...... Equation 1

-(5y+2) + y = 5

Hence, Option A is the correct option

Answer:

The volume of the sphere is 972π mm³

Step-by-step explanation:

To calculate the volume of a sphere we have to use the following formula:

V = volume

r = radius  = 9mm

π = pi

V = ⁴⁄₃πr³

we replace with the known values

V = ⁴⁄₃ * π * (9mm)³

V = π * ⁴⁄₃ *729mm³

V = π * 972mm³

V = 972π mm³

The volume of the sphere is 972π mm³
