Answer:
3,4,5 forms a right triangle
1,2 ,9 does not form a triangle
Step-by-step explanation:
Three side lengths that will form a triangle
3,4,5
This is a Pythagorean triple. It forms a right triangle
3^2 +4^2 = 5^2
9+16=25
25=25
Three side lengths that will not form a triangle
1,2 9
The sum of the two smaller sides must be greater then the third
1+2 < 9 not greater
When b=0
f(x)=ax^2+c
test each
A. with x^2-1, A is false
B. with -x^2-1, B is false
C. cannot find contradiction
D. the axis is actually x=0, 0 is nithere positive nor negative, false
answer is C
Answer:
U.S. Currency
Step-by-step explanation:
Answer:
21.33 to nearest hundredth
Step-by-step explanation:
Inverse Variation is y = k / x where k is a constant.
Plug in the given values to find k:-
16 = k/4
k = 4*16 = 64 so the equation of variation is y = 64/x.
So when x = 3, y = 64/3 = = 21.33 to nearest hundredth.
Subtraction is. Pemdas. Whichever comes first left to right is what you should do. In this case subtraction comes before addition, therefore subtraction is the right route
