HELP !! Statement

Reason

1. Draw a line through B that is perpendicular to and

label the point of intersection with as D.

construction

2. In ΔABD, BD = c sin A.

definition of sine in a right triangle

3. In ΔCBD, BD = a sin C.

definition of sine in a right triangle

4. c sin A = a sin C

Substitution Property of Equality

5. dividing throughout by sin A sin C

6. Draw a line through A that is perpendicular to and

label the point of intersection with as E.

What is the missing statement in step 10 of the proof?

Given: ΔABC

with AB = c, BC = a, AC = b

Prove: a/sin a = b/ sin b = c/ sin c

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
