Divide the length of the segment by 4
Answer:
its 13 if i saw the numbers right
Step-by-step explanation:
evaluate then you get the below
1-(-4)x(-3)+12/(-6)
___________
-1
divide and get;
-(1-(4)x(-3)+12/(6))
remove parentheses and divide
-(1+4x(-3)-2)
multiply and get
-(1-12-2)
calculate
-(-13)
remove "()"
and you get 13
Given that the point (12,-5) which takes the form (x,y), This implies that:
opposite=-5
adjacent=12
thus using using Pythagorean theorem, the hypotenuse will be:
c^2=a^2+b^2
plugging the values we obtain:
c^2=(12)^2+(-5)^2
c^2=144+15
c^2=169
thus
c=13
but
cos θ=adjacent/ hypotenuse
therefore:
cos θ=12/13
Answer is option . D
Answer:
The door has a width of 6.26 feet, with a height of 12.52 feet.
Step-by-step explanation:
You can solve this by taking two pieces of information we're given:
1) the diagonal size of the doorway is 14 feet
2) the height of the doorway twice its width
First lets describe the width and height using the diagonal length. We can do that with the Pythagorean theorem:
w² + h² = 14²
Now we can use the relationship between the width and height to eliminate one variable:
w² + (2w)² = 14²
w² + 4w² = 14²
5w² = 196
w² = 39.2
w ≈ 6.26
So the door has a width of 6.26 feet, with a height of double that, 12.52 feet.
Answer: B and E apply. I know for sure.
