What is the eighth value in the sequence 768, 384, 192, 96, ...?

Step-by-step explanation:

a/b × c/d = (a×b)/(c×d)

so,

-4/9 × 11/12 = (-4×11) / (9×12) = -44/108 = -11/27

The rate of change of the height of the top of the ladder above the ground at the instant when the base of the ladder is 30 ft. from the base of the building is -3 ft./min.

The rate of change of the height of the top of the ladder above the ground at the instant when the base of the ladder is 30 ft. from the base of the building is -3 ft./min. This rate takes into account the fact that the ladder is slipping at a rate of 3 ft./min. As the base of the ladder is slipping away from the building, the top of the ladder is moving down, hence the negative rate of change. This rate of change will remain the same until the base of the ladder has slipped the full 50 ft. from the base of the building. At this point, the rate of the change of the height of the top of the ladder will be 0, since the ladder will no longer be slipping.

The rate of change can be calculated as follows:

Rate of change = Change in height / Change in time

Change in height = Initial height - Final height

Initial height = 50 ft.

Final height = 50 ft. - 30 ft. = 20 ft.

Change in time = 30 ft. / 3 ft./min. = 10 min.

Rate of change = (50 ft. - 20 ft.) / 10 min. = -3 ft./min.

Step-by-step explanation:

As per the rule of function, the relation ​(4,4), (5,6),​ (6,8), (6,10),​ (7,12) is a function.

The term relation in math referred as the relationship between two or more set of values.

Here we have to find in which of the given relation is a function.

As we all know that the function is a relation which describes that there should be only one output for each input or we can say that a special kind of relation (a set of ordered pairs),

Therefore, the rule of the function states that every X-value should be associated with only one y-value is called a function.

As per this rule we have identified the following relation is one that said to be the function

Thee volume of the cone has a value of 1, 739. 60 cubic feet

The formula for calculating the volume of a cone is expressed as;

V = πr²h/3

Where;

From the information given, we have the values as;

Diameter = 19

But radius = Diameter/2

Now, radius = 18. 7/2 = 9.35 ft

Substitute the values into the formula

Volume = 3. 142( 9.35)² × 19/3

Find the value of the square

Volume = 3. 142(87. 42) × 6. 3

(a) The net force acting on this object at t = 1 s is 88 N.

(b) The net force acting on this object at t = 4 s is 0 N.

(c) The net force acting on this object at t = 7 s is -13.2 N.

In the given question, the velocity graph of a 2.2 kg object as it moves along the x-axis.

The given mass = 2.2

a) We have to find the net force acting on this object at t = 1 s.

At t=1 s

Slope of a graph = acceleration

Acceleration = slope

Acceleration = 12/3

Acceleration = 4 m/s^2

Net force, F = m*a

F = 22*4

F = 88 N

So the net force is 88 N.

b) We have to find the net force acting on this object at t = 4 s.

At t = 4 s

Acceleration, a=slope of graph

a = ( 12 - 12) /(3 - 0)

a = 0 m/s^2

The net force , F = m * a

F = 2.2 * 0 = 0 N

c) We have to find the net force acting on this object at t = 7 s.

At t = 7 s

Acceleration, a = ( 0 - 12 ) / (8 - 6)

a = - 6 m/s^2

The net force, F = m * a

F = 2.2 * (-6)

F = -13.2 N

Let x be the number of miles the driver still has to travel.

The driver traveled 120 + 120/4 + 120/42/3 = 120 + 30 + 40 = 190 miles.

So the remaining distance is x + 190 = 55 + 1 2/3 * x

Multiplying both sides by 3/2 gives 3/2x + 3/2190 = 3/255 + 3/2*x + x

This simplifies to x = 190.

Therefore, the driver still has to travel 190 miles.

The cost of the book before the sales tax is $31

From the question, we have the following parameters that can be used in our computation:

Sales tax = 5%

Cost of book = $32.55 after tax

The cost of the book before tax is calculated using the following equation

Cost of book after tax = Cost of book before tax * (1 + Sales tax)

Substitute the known values in the above equation, so, we have the following representation

32.55 = Cost of book before tax * (1 + 5%)

Evaluate the sum

So, we have the following representation

32.55 = Cost of book before tax * (1.05)

Divide both sides by 1.05

Cost of book before tax = 31

Hence, the cost is $31

Answer:

Step-by-step explanation:

You want the number of months and the total amount paid when you pay off a credit card debt of $1367.90 with 9.5% APR at the rate of $400 each month.

The amount of the payment that goes to interest each month is the monthly rate (9.5%/12) multiplied by the remaining balance. The first month's interest is ...

  $1367.90 × 0.095/12 = $10.8292 ≈ $10.83 . . . . rounded to cents

Then the balance is reduced by ...

  $400 -10.83 = $389.17

so it becomes ...

  $1367.90 -389.17 = $978.73 . . . . . balance after first payment

These calculations are repeated for subsequent payments. It is convenient to let a spreadsheet do them. (It can round the interest for you.) The results are shown in the attachment.

The negative balance for month 4 reflects the overpayment that a payment of $400 would be. The actual month 4 payment is the previous balance ($191.12) together with the interest due on that ($1.51), so is $192.63.

The total repaid is the sum of interest charges ($24.73) and the initial balance ($1367.90). That is, you paid off the initial balance and the interest due.

You repaid a total of $1392.63 in 4 months.

__

Additional comment

The steps for computing the total repaid are ...

Note, there are formulas for the payoff time and the total repaid. However, they do not take into account rounding of intermediate values, and they presume the last payment is made partway through the month. In short, it only gives an approximation of the amount repaid.

By listing actual amounts, rounded to cents, the actual amount repaid can be figured with no error. A spreadsheet is very helpful for that.

The value of a + c in the equation is -5

From the question, we have the following parameters that can be used in our computation:

y = ax² + 5x + c

x- intercepts at 1 and 3

When x = 1 and 3, the value of y is 0

So, we have

When x = 1:

a(1)² + 5(1) + c = 0

a + 5 + c = 0

a + c = -5

When x = 3:

a(3)² + 5(3) + c = 0

9a + 15 + c = 0

9a + c = -15

The tangential and normal components of the acceleration when s = 10 m is 40 m/s^2 and 8 m/s^2 respectively.

In the given question, a car is travelling along the road with a speed of 2s m/s, where s is in meters.

We have to determine the tangential and normal components of the acceleration when s = 10 m.

Speed (v) = 2s  

Motion is circular so, Radius of circle = 50m

Tangential acceleration = dv/dt

Tangential acceleration = d(2s) / dt

Tangential acceleration = 2(ds)/dt

Tangential acceleration = 2v

Tangential acceleration = 2(2s)

Tangential Acceleration = 4s

As given s = 10 m

Tangential acceleration = 4 x 10

Tangential acceleration  = 40 m/s^2

Normal acceleration = v^2/ r

Normal acceleration = 4s^2/r

Normal acceleration = {4 x 10^2}/50

Normal acceleration = {4 x 100}/50

Normal acceleration = 400/50

The values of v and w are 12 and 20 respectively which makes ΔPQR ≅ ΔIJK (Congruent right triangles).

Two triangles are said to be congruent if their shape and size are the same. If two right triangles are said to be congruent, then they must have equal measures for their corresponding sides and angles.

The given two right triangles are congruent. I.e., ΔPQR ≅ ΔIJK

So, their corresponding sides QR = IJ and PR = IK, and the corresponding angle ∠Q = ∠J.

But we have QR = w - 1; IJ = 3w - 41; PR = 6v-12; IK = 5v

So, on equating them, we get

QR = IJ ⇒ w - 1 = 3w - 41

⇒ 3w - w = 41 - 1

⇒ 2w = 40

∴ w = 20

And

PR = IK ⇒ 6v-12 = 5v

⇒ 6v - 5v = 12
