C, 965.
$122 * 30(months)= 3660
3660 - 2695 = 965
Csc^2 x = 1 + cot^2 x
so the denominator = csc^2 x
1 / csc^2 x = sin^2 x Answer
Hello!
As we know, Distance is found by the standard formula of: D = RT. This tells us that Distance is equal to the Rate (of speed) multiplied by the Time driven at that speed. A simple re-arraignment of the formula is all that is required to find any one of the three terms if the other two quantities are known.
<span>As you are trying to determine how long the trip will take, the Time, you must divide the Distance by the Rate of speed you are traveling. This equation will be: T = D/R. </span>
<span>To determine the Rate of speed, the Distance is divided by the Time the trip took: R = D/T. </span>
<span>There you have it, Blackbetty, three equations to calculate which ever of the three unknowns that is needed. This should help you with this problem. Let us know if you have any more questions!
</span>
For more info:
The original formula for distance is:
<span>d = distance </span>
<span>r = rate </span>
<span>t = time </span>
<span>d = rt </span>
<span>If you want to know distance, use: </span>
<span>d = rt </span>
<span>If you want to know the rate, use: </span>
<span>r = d / t </span>
<span>If you want to know the time, use: </span>
<span>t = d / r </span>
<span>The answer is t = d / r

Hope this Helps! Have A Wonderful Day! :)
Using the normal distribution, it is found that the lengths for which a bolt will be destroyed are given by:
A. A bolt will be destroyed if the length is less than 11.8 cm or greater than 12.2 cm.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
The bounds within 4 standard deviations of the mean are , hence:
X - 12 = -4 x 0.05
X = 11.8
X - 12 = 4 x 0.05
X = 12.2
Hence:
A. A bolt will be destroyed if the length is less than 11.8 cm or greater than 12.2 cm.

Answer:
∠ P = 40°
Step-by-step explanation:
Since PQ = PR then the triangle is isosceles and the base angles are congruent, then
∠ R = ∠ Q = 70° , so
∠ P = 180° - (70 + 70)° ← sum of angles in triangle is 180°
∠ P = 180° - 140° = 40°
