Answer:
Answers are below
Step-by-step explanation:
-3x > 9 Divide both sides by -3
x < -3 When you divide by a negative number, flip the inequality sign
3x > 9 Divide both sides by 3
x > -3
When you divide by a negative number, flip the inequality sign. This affects your answer because the first inequality means any number less than -3, while the second inequality means and number above -3
Answer:
Cot is the abbreviation of Cotangent. In mathematics, there are some functions called as the Trigonometric Functions, which used to relate the angles of a triangle to the lengths of the sides of a triangle.
Answer:
-3.872983346
Step-by-step explanation:
In this case we have: cos θ = 1/4 Whose possible solutions are: θ = 2 * pi * n - Acos (1/4) θ = 2 * pi * n + Acos (1/4) Where, n belongs to the natural numbers. As sin θ <0 then the solution is: θ = 2 * pi * n - Acos (1/4) For n = 1 we get: θ = 4.965069236 radians Thus: tan θ = tan (4.965069236) = - 3.872983346 Answer: tan θ = -3.872983346
Answer:
q = -13
Step-by-step explanation:
The given equation is:
Taking 2 as common from left hand side, we get:
The square of difference is written as:
Equation 1
If we compare the given equation from previous step to formula in Equation 1, we note that we have square of first term(x), twice the product of 1st term(x) and second term(2) and the square of second term(2) is missing. So in order to complete the square we need to add and subtract square of 2 to right hand side. i.e.
Comparing the above equation with the given equation:
, we can say:
p = 2 and q= -13
The area of the first rectangle would be 18cm² and the area of the second rectangle would be 12cm².
<h3>How to calculate the area of a rectangle?</h3>
To calculate the area of a rectangle we must apply the following mathematical formula:
According to the above, to calculate the area of the rectangles we must multiply the length of the side by the base as shown below. We must also take into account the table that will give us the value of X that we do not know:
- 3cm × 6cm = 18cm²
- 2cm × 6cm = 12cm²
Finally, to know how much the area of both rectangles adds up, we add both values:
12cm² + 18cm² = 30cm²
