Answer:

It will grow '2d'

Step-by-step explanation:

Given,

The increment per day in the height of plant = 2 cm,

Total number of days = d,

Thus, the growth of plant in d days = growth of plant per day × number of days

=2d

Hence, the required expression that shows the growth of plant is,

2d

3.4=21 2.5=7. 4.4=؟​
Licemer1 [7]

Answer:

32

Step-by-step explanation:

From the given values

The possible logic could be

if x.y is given

then it is equal to=\frac{(x+y)\times x}{y-3}

For 1st example

3.4=\frac{(3+4) \times 3}{4-3} =\frac{21}{1} =21

For 2nd example

2.5=\frac{(2+5) \times 2}{5-3} =\frac{7 \times 2}{2} =7

⇒4.4=\frac{(4+4)\times 4}{4-3} =32

A ball was dropped from a height of 60m. Each time it hit the ground, it bounced up 1/2 (half) of the height that it dropped. Ho
asambeis [7]

Answer:

The ball traveled 116.25 m when it hit the ground for the fifth term

Step-by-step explanation:

This is a geometric progression exercise and what we are asked to look for is the sum of a GP.

The ball was dropped from a height of 60 m. This means that the initial height of the ball is 60 m.

First value, a = 60

Each time it hit the ground, it bounced up 1/2 (half) of the height that it dropped.

This is the common ratio, r = 1/2 = 0.5

The number of terms it hits the ground is the number of terms in the GP.

number of terms, n = 5

The distance traveled by the ball when it hit the ground for the fifth term will be modeled by the equation:

S_n = \frac{a(1 - r^n) }{1 - r} \\S_5 =  \frac{60(1 - 0.5^5) }{1 - 0.5}\\S_5 =  \frac{58.125}{0.5} \\S_5 = 116.25 m

7+3x-12x=3x+1 is it Infinitely many solutions, one solution, or no solutions with steps please
alisha [4.7K]

Answer:

  • One solution

Step-by-step explanation:

  • 7 + 3x - 12x = 3x + 1
  • 7 - 9x = 3x + 1
  • 3x + 9x = 7 - 1
  • 12x = 6
  • x = 6/12
  • x = 1/2

It has one solution
