Gravity pulls the metal down at 10 N, but the metal pieces RISES! At least how much force is needed to make it move upward?
prisoha [69]

Answer: Greater than 10 N

Step-by-step explanation:

Given

Gravity force on metal is 10 N

But the metal piece is rising i.e. there must be an upward force greater than 10 N

Suppose the force is F

So, we can write

\Rightarrow F>10\ N

Any force greater than 10 N is sufficient for the metal to move upwards

The greater the amount of force faster will be the movement

Natali [406]
Hello!

First of all let's divide and find how much each calculator cost.

95.2/14=$6.80

Now we will subtract from 24.

24-6.8= 17.2

Mr. Morris has $17.2 left to spend on each student.

I hope this helps!

20 POINTS AND WILL GIVE BRAINLIEST IF MORE THAN ONE ANSWER!
pickupchik [31]

Answer:

Step-by-step explanation:

or

Step-by-step explanation:

has:

1) amplitude=|a|

2) phase shift=b

3) period=2pi/c

d) vertical shift=d

--------------------------------------------------

You are given the amplitude is 2. This means a could either be 2 or -2.

You are given phase shift is -1/8. This means b is -1/8.

You are given the period is pi. So we need to solve pi=2pi/c.

pi=2pi/c

Dividing both sides by pi gives:

1=2/c

Multiply both sides by c gives:

c=2

The vertical shift is -2 so d=-2.

The equation could either be:

y=2cos(2(x-(-1/8)))-2

or

y=-2cos(2(x-(-1/8)))-2

Simplifying a little gives:

y=2cos(2x+1/4)-2

y=-2cos(2x+1/4)-2
