here are five rods a-1 a a a a+3 all measurements are in cm the total length of the five rods is l cm find a formula for l in te
Elenna [48]

Answer:

I=5a+2 (simplified form)


Step-by-step explanation:

I is the total length of all the 5 rods.

Each of the 5 parts lengths are (a-1), a, a, a, (a+3), respectively.


<em>We add all of them and equate it to I:</em>

I=(a-1)+a+a+a+(a+3)

<em>Simplifying this, we take like terms and add:</em>

<em>I=(a-1)+a+a+a+(a+3)\\I=5a-1+3\\I=5a+2</em>

Explain how to solve 4^(x+3)=7 using the change of base formula log_by=log y/ log b. Round to the nearest thousandth
HACTEHA [7]

Answer:

x = -1.59

Step-by-step explanation:

We are here given a equation and we need to solve out for x. The given equation is ,

\sf\longrightarrow 4^{( x +3)}= 7

Take log to the base " e " on both sides , so that we can remove the variable from the exponent .

\sf\longrightarrow log_e 4^{x+3}= log_e 7

Simplify using the property of log , \sf log a^m = m log a , we have ,

\sf\longrightarrow (x + 3) ln 4 = ln 7

Distribute by opening the brackets ,

\sf\longrightarrow  x ln 4 + 3 ln 4 = ln 7

This can be written as ,

\sf\longrightarrow x ln 4 = ln 7 - 3ln4

Divide both sides by ln 4 ,

\sf\longrightarrow x = \dfrac{ ln7}{ln 4 } - \dfrac{ 3ln4}{ln4}

Simplify ,

\sf\longrightarrow x = \dfrac{ ln4 }{ln7 } -3

On simplifying , we will get ,

\sf\longrightarrow \boxed{\blue{\sf x = -1.59 }}
