Answer:

Because it's measure the speed according to the car distance traveled and not the direction of the car movement.

Step-by-step explanation:

The newer cars have digital speedometers; the display would register as a forward speed while backing; and the odometer a positive distance as well. ... In those cars the odometer could run in reverse, subtracting miles.

Find the coordinates of point P that partition AB in the

Ira Lisetskai [31]

Answer:

(1.6, 0)

Step-by-step explanation:

Point P, partitioning AB in the ratio 1:4, implies that it divides AB into, AP and PB, such that AP to PB = 1:4.

Use the formuka below to find the coordinates of point P:

$x = \frac{mx_2 + nx_1}{m + n}$

$y = \frac{my_2 + ny_1}{m + n}$

Where,

$A(1, -1) = (x_1, y_1)$

$B(4, 4) = (x_2, y_2)$

$m = 1, n = 4$

Solve by plugging the above values where necessary as follows:

$x = \frac{mx_2 + nx_1}{m + n}$

$x = \frac{1(4) + 4(1)}{1 + 4}$

$x = \frac{4 + 4}{5}$

$x = \frac{8}{5}$

$x = 1.6$

$y = \frac{my_2 + ny_1}{m + n}$

$y = \frac{1(4) + 4(-1)}{1 + 4}$

$y = \frac{4 - 4}{5}$

$y = \frac{0}{5}$

$y = 0$

The coordinates of P that partitions AB into the ratio 1:4 are (1.6, 0)

the cost of circular mirrors is directly proportional to the square of the diameter. a circular mirror with a diameter of 60cm c

defon

When 'y' is directly proportional to 'x', we express this by

y = kx

where 'k' is the constant, which we need to work out first

Cost of circular mirrors = (k) (diameter)²
50 = k(60)²
50 ÷ 3600 = k

the proportional formula is

y = (1/72)x²

The cost of the mirror when diameter = 90cm

y = (1/72) (90)²
y = 112.5

Answer: $112.50
