Answer:
Range(R)= (5,1,-4,-3)
Step-by-step explanation:
f={ (2,5) , (-6,1) , (0,-4), (4,-3), (7,-3) }
Same range is not repeated.
Answer:
Acute.
Step-by-step explanation:
Using the Triangle Inequality Theorem you know that the sum of the lengths of two sides of a triangle are greater than the length of the third side.
Using this we can narrow it down that this DOES have a solution, since 10+12>15.
Now, we can determine if this triangle is a right triangle using the Pythagorean Theorem. C is the longest length.
If c^2= a^2+b^2, then it is a right triangle.
If c^2< a^2+b^2 then it is an acute triangle.
If c^2>a^2+b^2 then it is an obtuse triangle.
We can now substitute. (A and B are interchangeable, but C is the longest length.
A=10
B=12
C=15
A^2=100
B^2=144
C^2=255
We can now figure out that this triangle is acute because A^2+ B^2 (244) < C^2 (255).
Hope this helps!
Answer:
14%
Step-by-step explanation:
42 is divisible of 3, the same with 300, if you put this equation into a fraction (42/300) and divide by 3, you should end up with 14/100 which is equal to 14%.
Step-by-step explanation:
y-5=1/2(x+8) =
2(y-5)=x+8
2y-10=x+8
2y=x+18
2y-x-18=0
