GuDViN [60]3 years ago
8 0

Answer:

According to logarithmic properties.... The right hand side can be written as

log base 7 (180/3).....which is log base 7 60

So according to the question cancel out the log base 7 from both sides....

Then we get 8r + 20 = 60

That is 8r = 40..

That is r = 5......

Therefore the value of r is 5

Water flows through a pipe of diameter 4cms with a velocity of
MissTica

Answer:

  1.28 m

Step-by-step explanation:

The speed at which water rises in the tank is proportional to the speed of the water in the pipe and inversely proportional to the ratio of the tank area to the pipe area.

The ratio of tank area to pipe area is the square of the ratio of their diameters:

  ((150 cm)/(4 cm))² = 1406.25

Then the rate of rise of water in the tank is ...

  (0.5 m/s)/(1406.25)

After 1 hour = 3600 seconds, the height of the water will be ...

  rise = (time)(rate of rise)

  (3600 s)(0.5 m/s)/1406.25 = 1.28 m

The image of a figure is shown. What are the coordinates of X in the pre-image of the figure if the rule that created the image
nydimaria [60]

The coordinates of X in the pre-image of the figure is (3.2, 0.6) if the  transformation rule is T_(-5.2, 1.4)(x, y)

<h3>What is geometric transformation?</h3>

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

As we can see in the figure.

The transformation rule is T_(-5.2, 1.4)(x, y)

X'(-2, 2)

Before the transformation:

X = (-2+5.2, 2-1.4)

X = (3.2, 0.6)

Thus, the coordinates of X in the pre-image of the figure is (3.2, 0.6) if the  transformation rule is T_(-5.2, 1.4)(x, y)
