Answer:
cotx - cot2ⁿxStep-by-step explanation:
Note: finding the sum not xFirst rewrite the first term as:
1/sin2x = sinx / (sinxsin2x) = sin(2x-x) / (sinxsin2x) =(sin2xcosx - cosxsinx) / (sinxsin2x) = (sin2xcosx)/(sinxsin2x) - (cos2xsinx)/(sinxsin2x) = cosx/sinx - cos2x/sin2x = cotx - cot2xNow the sum is:
S = cotx - cot2x + cot2x - cot4x +... + cot2ⁿ⁻²x - cot2ⁿx =cotx - cot2ⁿx12 points

A cheetah's speed was timed overa

(PLEASE HELP ME)clocked running 70 miles per hour. Which
equation shows the relationship between
the distance, y, and time, x, the cheetah
runs?
Answers
Answer:
y = 70x
Step-by-step explanation:
Note that d = rt where d is the distance, r is the rate/speed, and t is the time. Since we are given that the variable x is the time, 70mph is the speed, and the variable y is the distance, we can substitute these into d = rt, which we get y = 70x.

Solve the inequality.
8+k≤−3
The solution is
.
Answers
Answer: k [tex]\leq[/tex] -11
Step-by-step explanation:
8 + k [tex]\leq[/tex] -3 Subtract 8 from both sides
-8 -8
k [tex]\leq[/tex] -11
The solution to the given inequality 8 + k ≤ -3 is k ≤ -11 which represents all values of k that are less than or equal to -11.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
The given inequality is given in the question:
8 + k ≤ -3
To solve the inequality 8 + k ≤ -3, you can start by subtracting 8 from both sides to isolate the variable:
k ≤ -3 - 8
k ≤ -11
The solution to this inequality is all values of k that are less than or equal to -11. This includes all negative numbers less than or equal to -11, as well as -11 itself.
Therefore, the solution to the given inequality is k ≤ -11.
