I really need help with this trigonometric function, i am struggling and it would mean a lot.
In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are real functions that relate an angle of a right-angled triangle to ratios of two side lengths. There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant and cotangent. These six trigonometric ratios are abbreviated as sin, cos, tan, csc, sec, cot.
I would suggest calculator soup they have a trigonometric function calculator
And here is how to solve trigonometric function,
Put the equation in terms of one function of one angle.
Write the equation as one trig function of an angle equals a constant.
Write down the possible value(s) for the angle.
If necessary, solve for the variable.

why is angel 6 congruent to angel 2
Step-by-step explanation:
Angle 6 is only equal to angle 2 if the lines are parallel. The horizontal line is being intersected by two lines, if they are parallel then <6 = <2. They are equal because the horizontal line is straight, meaning anything crossing it that are parallel wil creat equal angles
When solving an inequality that results in negative x, we must reverse the inequality and reverse the signs of all the numbers.

The number of calories in a one ounce serving of a certain chicken sandwich is a random variable with mean 110 calories. The number of calories in a full cup of lemonade is a random variable with mean 140 calories. For lunch, you eat one ounce of the chicken sandwich and LaTeX: \frac{1}{2}1 2 cup of lemonade. Let K be the random variable that represents the total number of calories in this lunch. The mean of K is
Answer:
The mean of K is 180 calories.
Step-by-step explanation:
Mean of a sum of normal distribution:
The mean of a sum of normal distributions is the sums of the mean.
In this question:
Lunch:
One ounce of chicken sandwich, with mean 110 calories.
Half a cup of lemonade, with mean 140/2 = 70 calories.
Let K be the random variable that represents the total number of calories in this lunch. The mean of K is
110 + 70 = 180 calories
The mean of K is 180 calories.

Find the area under the standard normal curve that lies outside the interval between z = -2.16 and z = 2.14
Answer:
The area is 0.0316
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X
Find the area under the standard normal curve that lies outside the interval between z = -2.16 and z = 2.14
Below z = -2.16 or Above z = 2.14
Below z = -2.16
z = -2.16 has a pvalue of 0.0154, which means that this area is 0.0154
Above z = 2.14
z = 2.14 has a pvalue of 0.9838, which means that this area is 1 - 0.9838 = 0.0162
Total:
0.0154 + 0.0162 = 0.0316
The area is 0.0316

A recipe for 12 scones requires 2 teaspoons of baking powder and 240 g of flour. If a larger number of scones are made, using 540 g of flour, how much baking powder is needed?
Answer:
45 teaspoons of baking powder

Which pair of angles must be supplementary?
VX
2.
6
3
4
5
21 and 26
22 and 25
0 25 and 24
Z6 and 22
Answer:
∠1 and ∠6
Step-by-step explanation:
Supplementary angles are two or more angles added together make 90°.
Right angles indicated by the small square at the corners.
∠2 and ∠5 are right angles.
So, any pair with ∠2 and ∠5 are not supplementary.
The only pair of angles that are not associated with ∠2 and ∠5 is: ∠1 and ∠6.

Leslie wants to build a 1,200 piece jigsaw puzzle. The completed puzzle will be in the shape of a rectangle that is 40 pieces in length by 30 pieces in width. Each piece is a square with an area of 0.25 in2. If Leslie wants to build the puzzle on a table that is at least 6 inches larger on all four sides than the complete puzzle, so that it makes a 6-inch border around the puzzle, what are the minimum dimensions of the table that she will need?
Answer:
If the area of each square piece is 0.25 in, that means that the dimensions must be 0.5 in by 0.5 in. Because the puzzle is 40 pieces by 30 pieces, that gives dimensions of 20 in by 15 in. Adding 6 inches on all four sides of the puzzle, we will have 32 in by 27 in for our minimum table dimensions.
Step-by-step explanation:
