this is for the Sin
*Remember that sin = opposite / hypotenuse*
a² + b² = c² (where a and b are legs and c is the hypotenuse)
From the picture, you can see:
a = 3
c = 4
Plug these into the equation and solve for b.
* a² + b² = c² *
step 1: 3² + b² = 4²
step 2: 9 + b² = 16
step 3: b² = 16 - 9
step 4: b² = 7
step 5: √(b²) = √7
step 6: b = ± √7
FOR COS:
From the picture, you can see that if θ is in quadrant II, b has to be negative.
b = -√7 = adjacent
Remember that cos θ = adjacent / hypotenuse.
cos θ = adjacent / hypotenuse
cos θ = (-√7 / 4)
Use the following function rule to find f(2).
Answer:
f(2)=-7-7|2|
=-7-14
=-21
Step-by-step explanation:
The x in f(x) is replace with 2,so example:
f(x) =3+4(x)
Find f(4),
f(4)=3+4(4)
=3+16
=19
The value of f(2) is -19 for f(x)=-7-7|x|
What is a function?A relation is a function if it has only One y-value for each x-value.
Given function is f(x)=-7-7|x|
f of x equal to minus seven minus seven times of mod x
f(x)=-7-7|x|
Now to find the value of f(2) we have to replace x value with 2
f(2)=-7-7|2|
f(2)=-7-12
f of two equal to minus seven minus twelve
f(2)=-19
f of two equal to minus nineteen.
Hence, the value of f(2) is -19 for f(x)=-7-7|x|

A polygon has 6 sides . The interior angles measures are 118°,127°,111°,123°,126°.and x° find the values of x .
The value of 'x' is 115 degrees and this can be determined by using the sum of interior angles property of hexagon.
Given :
A polygon has 6 sides. The interior angles measures are 118°, 127°, 111°, 123°, 126°, and x°.The following steps can be used in order to determine the value of x which is an interior angle of a hexagon:
Step 1 - According to the given data, the given polygon has 6 sides means that it is a hexagon with interior angles 118°, 127°, 111°, 123°, 126°, and x°.
Step 2 - The sum of interior angles of a hexagon is 720 degrees.
Step 3 - So, the values of 'x' can be calculated by using the below expression:
118 + 127 + 111 + 123 + 126 + x = 720
Step 4 - Simplify the above expression.
605 + x = 720
x = 720 - 605
x = 115 degrees

The graph shows the relationship between the number of strawberries eaten and the approximate number of calories consumed. Which statement is true?
Each strawberry contains 4 calories.
Each strawberry contains 3 calories.
Twenty-four strawberries contain 6 calories.
Four strawberries contain 15 calories.
9514 1404 393
Answer:
Each strawberry contains 4 calories
Step-by-step explanation:
The graph crosses the vertical line for 1 strawberry above the intersection with the horizontal line for 3, so there are more than 3 calories in 1 strawberry. The graph crosses "strawberries = 1" at about "calories = 4", matching the first statement.
Similarly, the graph crosses the vertical line for 4 strawberries above the horizontal line for 15 calories. An estimate of 16 calories for 4 strawberries is consistent with the first statement (4 calories in each strawberry).
The point (6, 24) is on the graph, but it means (6 strawberries, 24 calories), not the other way around.
The appropriate choice is ...
Each strawberry contains 4 calories
Answer:
its 4 calories, A
