Answer:

My answer is 8.428571429 ~ 8.43.

Step-by-step explanation:

First you can find log 5 which is 0.698970004 ~0.7. then you can use it to multiply the numbers in the bracket which will be 0.7x(x-7)=1...which will be 0.7x-4.9=1...then you will collect like terms which will be 0.7x=1+4.9 then it will be 5.9÷0.7 which will be equal to my answer above..Thank you for the question

Find the 7th term 18,6,2…
Veseljchak [2.6K]

If we look at the series, one third of the current term gives the numerical value of the next term.

If we need to express it algebraically, we can write the following equation.

  • a_{n+1}=\frac{a_{n}}{3}

Therefore, our common multiplier can be found as follows. Because this sequence is a geometric sequence.

  • \frac{a_{n+1}}{a_{n}} =r=\frac{1}{3}

In geometric sequences, any term can be written in terms of the first term. Below is an example.

  • a_{n}=a_{1}.r^{n-1}

Since we know the numerical values of the first term and the common factor of the series, we can easily find the seventh term.

  • a_{7}=a_{1}.r^{7-1}
  • a_{7}=18.(\frac{1}{3} )^6
  • a_{7}=\frac{2}{81}

For a moving object the force acting on the object varies directly from the objects acceleration when a force of 25 N acts on a
77julia77 [94]

Answer:

2m/s²

Step-by-step explanation:

If for a moving object the force acting on the object varies directly from the objects acceleration, then it can be expressed as:

F∝a

F = ka.

F is the force

a is the object's acceleration

From the expression;

k is the constant of proportionality

When an initial force of 25 N acts on the object and the acceleration of the object is 5 m/s², then

k = 25/5

k = 5Ns²/m

If the force exchange to 10 N, the acceleration of the object will be gotten using the relationship above

F = ka

Given F = 10N and k = 5Ns²/m

a = F/k = 10/5

a = 2m/s²

The acceleration of the object will be 2m/s²

The ratio between two no is 2:3 . if the consequent is 24 the antecendent is​
Irina18 [472]

antecedent : 16

ratio: 2 : 3

=========

antecedent : 2

consequent : 3

=============

\rightarrow \sf \dfrac{2}{3}=\dfrac{x}{24}           [ x is antecedent ]

\rightarrow \sf 2(24)=3(x)

\rightarrow \sf 48=3(x)

\rightarrow \sf x= 16

Additional information:

In the ratio, a : b  Here the "antecedent is a" and "consequent is b"
