It is cosine because ADJ/HYP is Cosine in Soh Cah Toa.
The ratio adjacent/hypotenuse shows the Cosine function.
What is Trigonometry?Trigonometric ratios are based on the value of the ratio of sides of a right-angled triangle and contain the values of all trigonometric functions. The trigonometric ratios of a given acute angle are the ratios of the sides of a right-angled triangle with respect to that angle.
We have,
To find the ratio equivalent to Adjacent / Hypotenuse.
We know that the ratio of an angle's perpendicular (opposite) side to its hypotenuse is known as its sine.
and, Cosine of an angle is defined as the ratio of the side adjacent to that angle to the hypotenuse.
or Cosine ratio = Adjacent/ Hypotenuse

its true the answer is true but would u need a whole Paragraph like an explanation I could make one for you.
The solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).
What is inequality?
inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
Given inequality will be solved as below:-
( - 5 / 2 ) ( 3x - 2 ) < 6 - 2x
Multiply the other hand by 2 and solve further.
( - 5 ) ( 3x - 2 ) < 2 ( 6 - 2x )
( - 5 ) ( 3x - 2 ) < ( 12 - 4x )
Take like terms to the same side and solve.
-15x + 30 < 12 - 4x
-15x + 4x < 12 - 30
-11x < - 18
x < 18 / 11
Therefore, the solution of the inequality ( - 5 / 2 ) ( 3x- 2 )< 6 - 2x. will be x < ( 18 / 11 ).

help plsss ^ _ ^ ….. !
Answer:
x = 6
Step-by-step explanation:
150 - x - 2x = 120 + 2x
place the like terms at the same side . So,
150 - x - 2x - 2x - 120 = 0
now add/subtract like terms
30 - 5x = 0
adding 5x on the both sides
30 = 5x
30/5 = x
6 = x

Data for length of the tail (in millimeters) and age (in days) of tadpoles is entered into a statistics software package and results in a regression equation of ŷ = 15 - 1.5x.
What is the correct interpretation of the slope if the length of the tail is the response variable and the age is the explanatory variable?
Using the slope concept, it is found that the correct interpretation is that each day, the length decreases by 1.5 millimetres.
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which
m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.b is the y-intercept, which is the value of x when y = 0.In this problem, the length of the tail, in millimetres, after x days, is given by:
[tex]y = 15 - 1.5x[/tex]
The slope is of [tex]m = -1.5[/tex], which means that each day, the length of the tail decreases by 1.5 millimetres.

A pipe is leaking at 1.5 cups per day. About how many gallons per week is the pipe leaking? (Hint: 1 gallon=16 cups)
Answer:
21/32 gal
Step-by-step explanation:
1 gallon equals 16 cups, so we first need to convert the rate from cups to gallons
1.5cup/1 x 1/16 gal
can be simplified to 3/32 gal
so we now multiply this rate by 7 for a week
so in total it leaks
3/32 x 7/1 = 21/32
