Answer:
The Proof for 
is below.
Step-by-step explanation:
To Prove:
Proof:
We know law of indices
Therefore,
Step 1: Applying law of indices
Step 2: Taking common 
we get
Step 3: 
so add 5 + 1 we get
Step 4: Cancel 6 from both denominator and numerator we get
...That is Divisible by 6 Proved
Answer
$266.66
Step-by-step explanation:
We have here ,
- Principal = $200
- Rate = 16%
- Time = 10 months = 10/12 yrs.
We can use the formula of SI to calculate the SI . After adding it to principal we will get the amount .
⇒ SI = P × R × T / 100
⇒ SI = $ 200 × 16 × 10 / 12 × 100
⇒ SI = $ 26.66
Now Calculate amount as ,
⇒ A = SI + P
⇒ A = $ 200 + $ 26.66
⇒ A = $ 226.66
I think Lettuce leaf but it isn't clear what you're asking.
Using formula sin^2 x +cos^2 x = 1 you get 1 - cos^2(9x) = sin^2(9x)
so in this way this fraction will be rewrited
sin9x/(1-cos^2(9x) = sin9x / sin^2(9x) = 1/sin9x
The Option A best explains the dual experiments: "In the experimental group, a chosen variable is altered in a known way. In the control group, that chosen variable is not altered so a comparison can be made."
<h3>What is experimental design?</h3>
- The process of deciding which variables to use in an experiment to test a particular hypothesis is called experimental design.
- To properly collect data and evaluate the hypothesis, the experimental design method is used.
Now,
- A specified variable is changed in the experimental group in a well-known fashion.
- That selected variable is left unaltered in the control group so that comparisons can be conducted.
- Control variables are variables that are utilized in an experiment to serve as a baseline against which the data from the experimental variables are gathered and evaluated (which is why the other answers are incorrect).
- In the experimental group, it is advisable to modify just one variable at a time so that any differences from the control group may be quickly linked to the one variable that was altered.
Hence, amongst all the given options, The Option A best explains the dual experiments: "In the experimental group, a chosen variable is altered in a known way. In the control group, that chosen variable is not altered so a comparison can be made."
