Answer:

The  position at time t  is  [tex]s(t) = 8t^2 - 14t -8[/tex]

Step-by-step explanation:

From the question we are told that

   The acceleration is  [tex]a = 16[/tex]

   The velocity at t = 0  is  [tex]v(0) = -14[/tex]

    The  position at time t =  0  is [tex]s(0) = -8[/tex]

Generally acceleration is mathematically represented as

     [tex]a(t) = \frac{d v}{dt }[/tex]

=>   [tex]\frac{dv}{dt} = 16[/tex]

=>   [tex]dv = 16 dt[/tex]

integrating both sides we have    

     [tex]\int\limits dv = \int\limits16 dt[/tex]

=>  [tex]v(t) = 16 t + c[/tex]

Now at t = 0  

     [tex]v(0) = 16 * 0 +c = -14[/tex]

=>  [tex]c = -14[/tex]

So

   [tex]v(t) = 16 t -14[/tex]

Generally the position of the body is mathematically represented as

     [tex]s(t) = \int\limits v(t)dt[/tex]

So

    [tex]s(t) = \int\limits 16t - 14 dt[/tex]

So  

    [tex]s(t) = 16 \frac{t^2}{2} - 14t + C[/tex]

Now  at t =  0

     [tex]s(0) = 16 \frac{0^2}{2} - 14(0) + C = -8[/tex]

=>    [tex]C = -8[/tex]

So

   [tex]s(t) = 8t^2 - 14t -8[/tex]

Rate of change of velocity with respect to time is known as acceleration.

Rate of change of displacement with respect to time is known as velocity.

Body position at time t is given by,   [tex]s(t)=8t^{2}-14t-8[/tex]

Data given are, a=16, v(0) = -14, s(0) = -8

Since,  [tex]\frac{dv}{dt}=a\\\\\frac{dv}{dt}=16\\\\dv=16dt[/tex]

Integrating both side

 We get,    [tex]v=16t + C[/tex]

Substituting v(0)=-14 in above equation

We get,   C = -14

  So,   [tex]v=16t-14[/tex]

Since, Rate of change of displacement with respect to time is known as velocity.

        [tex]v=\frac{ds}{dt}\\\\ds=vdt\\\\ds=(16t-14)dt[/tex]

Taking integration on both side

We get,   [tex]s=16\frac{t^{2} }{2}-14t+c[/tex]

Substituting s(0)= - 8 in above equation

We get,   [tex]c=-8[/tex]

So,  [tex]s=16\frac{t^{2} }{2}-14t-8\\\\s(t)=8t^{2} -14t-8\\[/tex]

Answer:

11 +13 + 15  = 39

Step-by-step explanation:

Let the consecutive odd integer be X , Y , Z .

X < Y < Z

Y = X + 2

Z = X + 4

Given ,

2 Y + X = 2 Z + 7

2 ( X + 2 ) + X = 2 ( X + 4 ) + 7

2 X + 4 + X = 2 X + 8 + 7

X = 15 - 4 = 11

So the integers are

11 , 13 , 15 .

Sum of integers = 39.

Answer:

Angle E = 70°

Step-by-step explanation:

Given parallelogram RELA, where m<R = 110°, to find m<E, recall the properties of a parallelogram.

Angle R and angle E are consecutive angles in parallelogram RELA.

One of the properties of a parallelogram states that any 2 consecutive angles in a parallelogram are supplementary. That is, they add up to 180°.

Therefore:

m<R + m<E = 180°

110° + m<E = 180°

Subtract 110° from both sides

m<E = 180° - 110° = 70°

Answer:

10 out of 12 which is [tex]\frac{5}{6}[/tex] when simplified

Answer:

9:12

Step-by-step explanation:

3:4 is the ratio of her shots to tries

x:12 is the ratio we want to find, so you can turn these into fractions: 3/4 to x/12

to find x you figure out what you multiply 4 by to get to 12, which is 3, so you multiply 3 by 3 and you get 9

so the answer is 9:12

Step-by-step explanation:

1/5^(6-4) = 1/5^2 = 1/25

Answer:

See below.

Step-by-step explanation:

So, from the figure, we can see that US is the combined length of UT and TS. In other words:

[tex]UT+TS=US[/tex]

We are given their equations. Substitute them:

[tex](x-3)+(12)=(3x-11)[/tex]

And this is our answer to 4.

Now, solve for x. Add on the left:

[tex]x+9=3x-11[/tex]

Subtract -3x from both sides:

[tex]-2x+9=-11[/tex]

Subtract 9 from both sides:

[tex]-2x=-20[/tex]

Divide both sides by -2:

[tex]x=10[/tex]

So, for 5, the answer is 10.

Answer:

a - about 3 packs cause you have to round up

b - $50.76

Step-by-step explanation:

First you divide 42 and 18.

42/18=2.33

You have to round up cause you can't have half of a pack, you can't just buy half of a pack.

So, it is rounded to 3 packs.

Next you have to multiply the number of packs and the cost of each pack of water bottles.

16.92*3=$50.76

a - you have to buy 3 packs

b - the total cost is $50.76

The amount of profit for selling one box is $7.5.

Option A is the correct answer.

A linear relationship on a graph describes a relation between two distinct variables x and y in the form of a straight line.

We have,

The graph models the linear relationship between the number of boxes of cards sold and its profit.

We see from the graph that when 4 boxes of cards are sold the profit made is $30.

This can be written as:

4 boxes = $30

Divide both sides by 4 we get,

1 box = 30/4

1 box = $7.5

Thus the amount of profit for selling one box is $7.5.

Option A is the correct answer.

Answer:

$6.00 to 95 cents = $6.95

Step-by-step explanation:

In currency the dollar is a whole number while the cent is a fraction of the dollar.

For the cent, every 100 cent is a dollar.

Converting the cent to dollar

100 cent = $1k

K= 100/1

95 cent = 100/1 x

95/100= x

0.95$= x

$6.00 to 95 cents = $(6+0.95)
