Answer:
root 49= 7^2
root 100= 10^2
root 144= 12^2
root 324= 18^2
root 441= 21^2
Step-by-step explanation:
Using the law of cosine for Triangle KJL, we can write:

Using the values of k,j and l, we can write:

Rounding to nearest integer, the measure of angle J will be 48 degrees.
So option B gives the correct answer
Answer:
10th term of the sequence 64,16,4... = 1/4096
Step-by-step explanation:
Points to remember
nth term of GP is given by.
Tₙ = ar⁽ⁿ⁻¹⁾
Where r is the common ratio and a is the first term
<u>To find the 10th term of given GP</u>
It is given that,
64, 16, 4,......
a = 64 and 6 = 1/4 Here
T₁₀ = ar⁽ⁿ⁻¹⁾
= 64 * (1/4)⁽¹⁰⁻¹⁾ = 64 * (1/4⁹)
= 4³/4⁹ = 1/4⁶ = 1/4096
In this question, we have o find the equation of line passing through point (1,1) and is perpendicular to the line

And slope of the given line is 5. And slopes of perpendicular lines are opposite and reciprocal of each other.
So slope of perpendicular line is

Using slope intercept form, which is

Substituting the values of x and y from the given point, and the value of m, we will get

adding 1/5 to both sides

So the required equation of line is
