If cos(x)= 2/3 and x is in quadrant I, then find exact values for (without solving for x): sin(2x) cos(2x) and tan(2x)
The exact values for sin(2x), cos(2x) and tan(2x) without solving for x 4√5 /9, -1/9 and -4√5 respectively
How to find the exact values for sin(2x) cos(2x) and tan(2x) without solving for x?Given: cos(x)= 2/3 and x is in quadrant IIn trigonometry, cos(x) = adjacent/hypotenuse = 2/3.
adjacent = 2
hypotenuse = 3
Here, we will find the opposite
opposite =√(3²-2²) = √5
sin(x) = (√5)/3 (opp./hyp.)cos(x) = 2/3
(adj./hyp.)tan(x) = (√5)/2 (opp./adj.)
Using trigonometry identity:
sin(2x) = 2sin(x)cos(x) sin(2x)
= 2× (√5)/3 × 2/3sin(2x)
= 4√5 /9cos(2x) = 2cos²(x) - 1
cos(2x) = 2(2/3)² -1cos(2x) = -1/9
Also, we will find the exact value for tan.
tan(2x) = 2tan(x) / 1-tan²(x)tan(2x) = (2(√5))/2 / 1-((√5)/2)²
tan(2x) = √5 / (-1/4)
tan(2x) = -4√5
Therefore, the exact values are given above.

Define Parallelogram.A unique variety of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.
The parallelogram's diagonals are the lines connecting its two opposed ends. Sharing into two equal portions is known as bisecting. Congruent refers to a copy that has the same dimensions as the original and may therefore be used in place of it. When the diagonals of a parallelogram bisect one another, it signifies that they split into two equal pieces that are congruent with one another.

If angle 1 is 25 degrees in the parallelogram pictured above, what is angle 2
The unknown angle in the parallelogram is as follows:
∠2 = 155 degrees.How to find angles of a parallelogram?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
In other words, a parallelogram is a two-dimensional geometrical shape whose sides are parallel to each other. Opposite sides are equal in length. Opposite angles are equal. The sum of any two adjacent angles of a parallelogram is equal to 180°
The sum of angles in a parallelogram is 360 degrees.
Therefore,
∠1 = 25 degrees
Hence,
Adjacent angles in a parallelogram are supplementary. This means adjacent angles sum up to 180 degrees.
Therefore,
∠2 + ∠1 = 180
∠2 + 25 = 180
∠2 = 180 - 25

in January the depth of a lake was 943 feet in August the depth of the lake was 754.4 what is the percentage decrease of the depth of the lake from January to August
The percentage decrease of the depth of the lake from January to August is 20%.
What is percentage decrease?The difference between the initial and final numbers is shown as a percentage reduction. It displays a percentage loss of value compared to the original regardless of the units. The decrease is equal to the initial amount less the final amount.
Given,
The depth of lake in January = 943 feet
The depth of lake in August = 754.4 feet
The difference is = (943-754.4) feet
= 186.6 feet
So, the percentage decrease of the depth of the lake from January to August will be = (186.6 ÷ 943) × 100

Your body mass index (BMI) is your weight by kilograms divided by the square of your height in meters. Online BMI calculators allow you to enter weight in pounds and height in inches. High BMI is a common but controversial indicator of being overweight or obese. A study by the National Center for Health Statistics found that the BMI of American young women (ages 20-29) is approximately Normally distributed with mean 26.8 and standard deviation 7.4
Using z-score calculations, we can say that around 13.14%of the young women have a BMI (Body Mass Index) of less than 18.5 and are underweight.
How to find the probability from z-score?The formula for z-score is;
z = (x' - μ)/σ
We are given;
Population Mean; μ = 26.8
Population standard deviation; σ = 7.4
Average BMI; x' = 18.5
Thus;
z = (18.5 - 26.8)/7.4
z = -1.12
From online p-value from z-score calculator, we have;

Cell phone Plan A costs $80 per month and comes with a free $630 phone. Cell phone Plan B costs $45 per month but does not come with a phone. If you buy the $630 phone and choose Plan B, how many months is it until your cost is the same as Plan A's? Be sure to:
a) Write an equation to represent the situation where x represents the number of months.
b) Show your work to solve the equation from part a using inverse operations.
c) State the answer.
a) An equation representing the situation where x represents the number of months when Plan A and Plan B cost the same is 80x = 630 + 45x.
b) Using inverse operations, we can state that 80x - 45x = 630 or 35x = 630, and x = 18.
c) From this equation, we determine that x is 18 months.
What is an equation?An equation is a mathematical statement that shows that two or more mathematical expressions are equal or equivalent.
Equations use the equation symbol (=) to depict the equality of the expressions.
Plan A Plan B
Monthly charge $80 $45
Free phone $0 $630
Mathematical Expression:Let Plan A = 0 + 80x
Let Plan B = 630 + 45x
The month the two plans' costs are equal can be derived by equating the two expressions above:
80x = 630 + 45x
80x - 45x = 630
35x = 630
x = 18 months
Thus, solving the equation, we can conclude that choosing Plan B will take 18 months to equal the cost of Plan A and thereafter, be considered cheaper than Plan A.

Group 1: 1, 2, 3, 4, 5

In this case, the sum of the numbers in Group 1 is 1 + 2 + 3 + 4 + 5 = 15, and the sum of the numbers in Group 2 is 6 + 7 + 8 + 9 = 30. The sum of the numbers in both groups is 15 + 30 = 45, which is the same.
Alternatively, we could create the following two groups:
Group 1: 1, 2, 3, 4

In this case, the sum of the numbers in Group 1 is 1 + 2 + 3 + 4 = 10, and the sum of the numbers in Group 2 is 5 + 6 + 7 + 8 + 9 = 35. The sum of the numbers in both groups is 10 + 35 = 45, which is the same.

The product of two consecutive odd integers is 99. Find the integers. Answer only with the positive integers. For example, if
the integers are 8, 10 and -8, -10, then answer 8, 10.
Provide your answer below:
n=
n =
Answer: n= 9 and n=11
Step-by-step explanation:
Assume that x is the lesser of the two numbers. The second figure must be x+2.
Since x*(x+2) = 99, we know that
x^2 + 2x - 99 = 0
We obtain x = 11 and 9 by searching for the roots of this equation.
This can also be resolved in the following ways:
We are aware that the two numbers (x and x +2) are consecutive odd numbers. Since x * (x + 2) = x2 + 2x, the value of x must be near to the square root of 99.
The squares 81 and 100 are the ones closest to the number 99. Additionally, we know that x * (x+2) is bigger than x2 (by a factor of 2x), therefore x must equal 9 and x+2 must equal 11.

There is enough storage in the truck. The volume of the septic tank is about 30,164 gallons.
How to determine if there is enough storage in the truck to drain a full septic tank?Given that:
Your company uses a truck with a storage tank capable of holding 30,500 gallons of waste.
A full septic tank in the shape of a cube measuring 191 inches on each side.
First, calculate the volume of the septic tank:
Volume of septic tank (V) = S³
where S is the side length of the septic tank
S = 191 inches
V = S³
V = 191³ = 6967871 cubic inches
Since we have 231 cubic inches in 1 gallon:
V = 6967871 / 231 = 30,164 gallons

Solve the triangle using the Law of Sines. (Assume b and c = 20, and ∠C = 63°. Round the length to two decimal places.)
Answer:
a = 16.51
angle A = 54
angle B = 63
Step-by-step explanation:
Recall the law of sines:
sinA/a = sinB/b = sinC/c
We know c is 20, and angle C is 63. Since b is also 20, angle B must also be 20. We know have two of the 3 angles, summing to 126, and we can find the last angle from that. 180-126=54, so angle A must be 54.
To solve for a, we need to know the ratio of the other two terms. Sin(63) is around 0.99, and 0.99/20 is 0.049. So we have 0.049=sin(54)/a. To solve for a, we divide by sin(54) and take the reciprocal of both sides, giving a = (sin54)/0.049, which is about 16.51, which is the length of the side a.
