Please help!! 13 points, will mark brainliest!! How to calculate [tex]cos (x)=\frac{6}{15}[/tex]?
I'm doing a trig question; trying to find angle XYZ, and I think the formula for the answer is C = [tex]\frac{A}{H}[/tex], which as stated in the title, I think in this situation is [tex]Cos(x)=\frac{6}{15}[/tex].
I don't know what I'm doing wrong, or if I've done the whole question wrong, but no scientific calculators will give me an answer because it says Cos is already defined. I know for sure the answer isn't 0.4, which was a guess I made. The entire question is attached below.
Answers
Answer:
66.4°
Step-by-step explanation:
Let ∠XYZ be x°.
Given the adjacent side, XY, and the hypotenuse side,YZ, we use cosine.
[tex] cosθ= \frac{adj}{hyp} \\ cosx° = \frac{6}{15} [/tex]
To find the value of x°, take the inverse of cosine.
[tex] x°\\ = cos^{ - 1} (\frac{6}{15} ) \\ = 66.4° \: (1 \: d.p.)[/tex]
Thus, ∠XYZ= 66.4°
*Given 2 sides, we can find the measure of an angle in a right- angled triangle by taking the inverse of the trigonometry function.

Which of the following is equivalent to the expression below?
(-k+8)(-2k²-8k-1)
A)2k³-8k²-63k-8
B)2k³-24k²-64k-8
C)-8k^4 +2k³+64k-8
D)-24k^4-2k³-64k²-8
Answers
Answer:
A
Step-by-step explanation:
(-k + 8)(-2k² - 8k - 1)
We can use FOIL to solve this.
(-k * -2k²) + (-k * -8k) + (-k * -1) + (8 * -2k²) + (8 * -8k) + (8 * -1)
2k³ + 8k² + k + (-16k²) + (-64k) + (-8)
2k³ - 8k² - 63k - 8

The product of two positive numbers is always greater than either number
Answers
The product of two positive numbers is always greater than either number the statement is false.
What are numbers?A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols. In several numeral systems, the same set of symbols may represent various numbers.
Given that the product of two positive numbers is always greater than either number.
To understand this let's take an example take two numbers and multiply them.
2 x 5 = 10
Then take 2 and 0.5 and multiply them.
2 x 0.5 = 1
Here the result of the product is 1 which is less than 2. Therefore, if the product of two positive numbers is always greater than either number the statement is false.

[tex]A = amplitude = \frac{(T_{max} - T_{min})}{2}\\\\[/tex]
