A particle is moving along the number line so that its distance (in meters) from the origin at any time t (in seconds) is given by s(t) = 8t2 + ln t.

The velocity of the particle at t = 1 second is:

Answers

Answer 1

Answer:

The velocity is 17 m/s

Step-by-step explanation:

To find the velocity, we find the first differential of the displacement

That will be

S’(t) = 16t + 1/t

We simply proceed to replace t with 1

That will give;

16(1) + 1/1

= 16 + 1 = 17 m/s

Anyone can find “v” and “u”??

Answers

Answer:

[tex]v = \frac{16}{3} \: \: and \: \: u = \frac{20}{3} [/tex]

Step-by-step explanation:

In triangle WYZ ,

[tex] {u}^{2} = {4}^{2} + {v}^{2} = 16 + {v}^{2} [/tex]

In traingle WXZ ,

[tex] {(3 + v)}^{2} = {5}^{2} + {u}^{2} [/tex]

Putting the value of U^2 in above eqn.

[tex] = > {(3 + v)}^{2} = 25 + (16 + {v}^{2} )[/tex]

[tex] = > {v}^{2} + 6v + 9 = 41 + {v}^{2} [/tex]

[tex] = > {v}^{2} - {v}^{2} + 6v = 41 - 9[/tex]

[tex] = > 6v = 32[/tex]

[tex] = > v = \frac{32}{6} = \frac{16}{3} [/tex]

Putting the value of V in eqn. below :-

[tex] {u}^{2} = 16 + { (\frac{16}{3} )}^{2} [/tex]

[tex] = > {u}^{2} = \frac{256}{9} + 16[/tex]

[tex] = > {u}^{2} = \frac{256 + 144}{9} = \frac{400}{9} [/tex]

[tex] = > u = \sqrt{ \frac{400}{9} } = \frac{20}{3} [/tex]

write 15% as a fraction step by step

Answers

Answer:

15/100

Step-by-step explanation:

15% is out of 100% so when writing it into a fraction it is 15 over 100, because 15% is out of 100%

Hint:If you want to put it into a decimal it will be 0.15 so when turning it into a fraction, the 1 is in the tenths place and the 5 is in the hundredths place.

How many groups of 1/2 days are in 1 week? Write a multiplication equation or a division equation to represent the question, then answer the question. *​

Answers

Answer:

14 groups

Step-by-step explanation:

Given

[tex]Groupings = \frac{1}{2}\ day[/tex]

[tex]Duration = 1\ week[/tex]

Required

Determine the number of group in the week

To do this, we simply divide the duration by the number half day group.

This gives:

[tex]Group = \frac{Duration}{Groupings}[/tex]

[tex]Group = \frac{1\ week}{1/2\ days}[/tex]

Convert week to days

[tex]Group = \frac{7\ days}{1/2\ days}[/tex]

[tex]Group = \frac{7}{1/2}[/tex]

[tex]Group = 7 / \frac{1}{2}[/tex]

Convert to multiplication

[tex]Group = 7 * \frac{2}{1}[/tex]

[tex]Group = \frac{14}{1}[/tex]

[tex]Group = 14[/tex]

Hence, there are 14 groups

3x-4 or = to 7


plz help

Answers

Answer:

3 + 4 = 7  which is true.

Step-by-step explanation:

Whenever you have an equation with a plain variable (that is, no exponent included), there is only one number that will work when substituted for x.

To solve it, you have to "undo" what is done to the variable. You also go in the reverse order of operations, so you do the addition/subtract first, then multiplication/division.

You also have to do the same to both sides, kind of like keeping a balance scale in balance.

In this case, we subtract 4 from both sides first:

3x + 4 -4 = 7 - 4

The + 4 - 4 cancel each other out, so you get:

3x = 3

3x means "3 times x" so you divide by 3 to undo it. I will use the / to indicate division:

3x / 3 = 3 /3  

so 1x = 1.

Since 1x is "1 times x" it is the same as x by itself, so:

x=1

AND, if we substitute 1 back into the original equation (the asterisk stands for multiply):

3 * 1 + 4 = 7

3 * 1 is 3, so:

3 + 4 = 7     which is true.

1 is the only number that works.

Hope this helped.
