Answer:

80N

Step-by-step explanation:

F = ma (Newton's second law)

When F=48N, a = 6m/s2

--> m = F/a = 48/6 = 8 (kg)

When a = 10m/s2

--> F = ma = 8 . 10 = 80N

What is the solution of this equation 4(x-8)+10=-10
Rom4ik [11]
<h2> 4(x - 8) + 10 = -10</h2><h2 />

Start by subtracting 10 from both sides.

This gives us 4x - 32 = -20.

Now add 32 to both sides to get 4x = 12.

Now divide both sides by 3 to get <em>x = 3</em>.

Answer:

13 l of 15%, 13 l of 25%, 26 l of 70%

Step-by-step explanation:

solutions:

  • 15%, 25% and 70%

final solution:

  • 52 l of 45%

This includes 0.45*52l= 23.4 l acid

Let's assume:

  • amount of 15% solution= x
  • amount of 25% solution= y
  • amount of 70% solution= z
  • and we have z=2y

so there are 2 equation:

  • x+y+z=52
  • 0.15x+0.25y+0.7z=23.4

or

  • x+y+2y= 52 ⇒ x+3y= 52 ⇒ x= 52- 3y
  • 0.15x+0.25y+1.4y=23.4
  • 0.15x+1.65y=23.4
  • 0.15*(52-3y)+1.65y=23.4
  • 7.8-0.45y+1.65y=23.4
  • 1.2y=23.4-7.8
  • 1.2y= 15.6
  • y=15.6/1.2
  • y= 13 l

--------

  • x= 52- 3*13= 13 l
  • z= 2y= 2*13= 26 l

You owe $300 on your credit card. For every month that you fail to make a payment, your balance increases by 1%. Find a formula
Vlada [557]

Answer:

B(t) = 300(1.01)^{t}

Step-by-step explanation:

The balance owed after t months can be given by an exponential function in the following format:

B(t) = B(0)(1+r)^{t}

In which B(0) is the initial balance owed and r is the growth rate, as a decimal.

You owe $300 on your credit card. For every month that you fail to make a payment, your balance increases by 1%.

This means, respectively, that B(0) = 300, r = 0.01

So

B(t) = 300(1+0.01)^{t}

B(t) = 300(1.01)^{t}
