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

consistent and dependent, or inconsistent.

Answers

the graph is attached, where the blue line is y=x+2 and the green line is 2y=2x-4.

since the two systems are parallel to each other and has no solution, this system is inconsistent.

Rewrite the equation to describe 4 as a function of 8:

Answer:

The steps below show how I transformed the equation in the question into standard form, where the slope and y-intercept is clearest. The slope is -1/2 and the y-intercept is 32.

[tex]4x + 8y = 512 \\ x + 2y = 64 \\ 2y = - x + 64 \\ y = - \frac{1}{2} x + 32[/tex]

how do I find the value of x in a isosceles and equilateral triangle​

Answers

Depends on where the x is. If in the equilateral triangle, x is the only angle missing then you do whatever two numbers they gave + x = 180 then solve.

If it’s in an isosceles and it’s the same situation, you do x = the side with the same amount of degrees (you will know because there will be a line on the “x” and given side

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.

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]

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
