Answer:
? ≈ 24°
Step-by-step explanation:
using the sine ratio in the right triangle
sin? = = , then
? = ( ) ≈ 24° ( to the nearest degree )
O y = 4
O y = 0
O y = 3
0y=-3
Answer:
To determine the value of the function at x = -3, we need to substitute -3 into the given function and evaluate it. Let's go through each option one by one:
1. y = 4: If this is the function, then substituting x = -3 would give us y = 4. However, this option does not match the given function.
2. y = 0: Substituting x = -3 into this function would give us y = 0. However, this option does not match the given function either.
3. y = 30: Substituting x = -3 into this function would give us y = 30. However, this option does not match the given function.
4. y = -3: Substituting x = -3 into this function would give us y = -3. This option matches the given function, so the value of the function at x = -3 is indeed y = -3.
Therefore, the correct answer is:
y = -3

If is a triangle 90°, 45°, 45° then the sides are in ratio 1 : 1 : √2.
If c = 12 is a hypotenuse, therefore we have the equation:
If c = 12 is a leg, therefore we have:
Answer:
Step-by-step explanation:
Given : If and
To find : Which expression is equivalent to ?
Solution :
We can write,
....(1)
We know, and
Substituting the values in (1),
Multiply term by term,
Therefore, The expression is equivalent to
Start at (0,4)
Then go down 3 and to the right 1 to arrive at (1,1)
The motion "down 3" means rise = -3
The "right 1" means run = 1
Therefore, slope = rise/run = -3/1 = -3
