Suppose you want to know how fast you traveled from the park to the library. As you moved, your speed varied from second to seco
frutty [35]

Step-by-step explanation:

In order to describe speed of an object, we must describe the average speed of the entire trip. It is equal to the distance moved divided by time taken.

If a person covers a distance of 1 km to the library in 15 minutes, we can find its average speed.

Firstly, we convert 15 minutes to hour, 15 min = 0.25 hours

Now, using formula of speed = distance/time

v=\dfrac{1\ km}{0.25\ h}\\\\v=4\ km/h

It means that the average speed of the person is 4 km/h. Hence, the given statement is true.

Mark is thinking of two numbers
11Alexandr11 [23.1K]

9514 1404 393

Answer:

  -2, 3

Step-by-step explanation:

For the product to be negative, exactly one of the two numbers must be negative. For the sum to be positive, the positive number must be larger than the absolute value of the negative number.

One such pair of numbers is -2 and 3.

__

Their product is -6; their sum is +1.

Find the distance from point a (7/8, -1/8) to point b (-1/8, 7/8)
VashaNatasha [74]

Answer:

 sqrt(2)    ≈1.414213562

Step-by-step explanation:

Distance is found by the formula

d =sqrt ( (x2-x1)^2 + (y2-y1)^2)

   = sqrt( (-1/8 - 7/8)^2 + (7/8 --1/8)^2)

      sqrt( (-8/8)^2 + (7/8 +1/8)^2)

       sqrt( (-1)^2 + (1)^2)

        sqrt ( 1 +1)

         sqrt(2)

If A and B are matrices and AB = I, which of the following represents the value of B?
Ratling [72]
If the product of 2 matrices are I this means that B is inverse matrix of A.
the matrix A has been given 
if we put symbols for the numbers in matrix A as shown below;
\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right] 

we need to first find the determinant (D)
D = ad - bc
where a = -1 , b = 4, c = -3 and d = 8
substituting these values 
D = -1x8 - (4x-3)
   = -8 +  12 = 4 
to find the inverse we need to exchange a and d and then multiply both b and c by -1
\left[\begin{array}{ccc}8&-4\\3&-1\\\end{array}\right]
and then have to divide all the terms in matrix by determinant (4)
\left[\begin{array}{ccc} \frac{8}{4} & \frac{-4}{4} \\  \frac{3}{4} & \frac{-1}{4} \\\end{array}\right]
the simplified inverse matrix B is;
\left[\begin{array}{ccc} 2 & -1 \\ \frac{3}{4} & \frac{-1}{4} \\\end{array}\right]
