Pretend the stuff under it cannot be touched when adding or subtracting
so (square root of 15) + (square root of 15) =
2(square root of 15)
Answer:
Option (d)
Step-by-step explanation:
From the given table,
Number of members in 1980 (t = 0) were 5400.
With the period of time number of members increased.
Let the number of years after 1980 = x
Therefore, line of best fit will be in the form of y = mx + b
Where b = Initial number of members = 5400
m = Increase in members in every 5 years duration
So the equation will be,
y = mx + 5400
From the given options,
Equation which matches to our equation is,
y = 310.58x + 5400
For the number of members in year 2022,
x = 2022 - 1980 = 42 years
y = 310.58(42) + 5400
y = 18445
Option (d) will be the answer.
Homer has made mistake in step 2
When you complete the square, you need to add the values to both sides of equation
<em><u>Solution:</u></em>
<em><u>Given equation of circle:</u></em>

Let us first calculate center and radius and find out where he did the mistake
<em><u>Step 1:</u></em>
Group the terms

<em><u>Step 2:</u></em>

But homers step 2 is:

So homer has made mistake in this step
When you complete the square, you need to add the values to both sides of equation
But homer did not add 49 and 1 to right side of equation
Correct steps are:

Comparing general equation of circle,

Therefore, center is ( 7, -1) and radius is 8.66
Answer:
D
Step-by-step explanation:
74 + 93 + 117= 284
360 - 284 = 76
Answer:
( 3n-8)
Step-by-step explanation:
so the given sequence is AP
where common difference is +3
nth term for this AP will be
(-5)+(n-1).(3) = 3n-8
