Answer:
OB
Step-by-step explanation:
The slopes are not changed.
See the picture of the 2 graphs. The slopes are the same,, but the y intercepts are different, so the lines are parallel.
Answer:
-√7/4
Step-by-step explanation:
Mathematically;
Sine is the ratio of opposite to hypotenuse
So here, hypotenuse is 4
The opposite is 3
To get the adjacent, we use the Pythagoras’ theorem which states that the square of the hypotenuse is equal the sum of the squares of the two other sides
Let the adjacent be x
4^2 = 3^2 + x^2
x^2 = 16-9
x^2 = 7
x = √7
The cosine is the ratio of the adjacent to the hypotenuse
Since we want to consider quadrant II
Cosine is negative here;
So the answer for Cos will be;
Cos theta = -√7/4
Answer:
First option
Step-by-step explanation:
The result of first expression:
7(6+z) multiply 7 with inside the parenthesis
7(6+z) = 42 + 7z
the result of second expression:
since we need to do multiplying first,
7*6 = 42 and 7*z = 7z
then we add them
42 + 7z this is the same result we found for the first equation
X-4y=6. 5x+y=8
minus X from both sides
4y=6. 4x+y=8
minus y from both sides
3y=6. 4x=8
y=2
X=-2
Answer:
The length of each side is 2m.
Step-by-step explanation:
A square has an area of s^2
Take the square root of 4 to find the length of each side.
The square root of 4 is 2.
