Answer: C. 14
Step-by-step explanation:
Answer:
Yes the triangles are congruent
Step-by-step explanation:
since
AB=CD
AD=CB
and BD= BD (common sides)
Therefore
the two triangles are congruent
Answer: It is Equation 1 and Equation 3
Step-by-step explanation:
The answer is 3 7/8 reduced because according to the order of operations we do the parenthesis first so we add -1/8 with 2/5 and then we will add the answer which was 11/40 then we add that to 3 3/5 and then we will get the answer 3 7/8 ( I reduced this so it would be in a nicer format.) have a nice day and god speed (:
Hello there!
To find the increasing intervals for this graph just based on the equation, we should find the turning points first.
Take the derivative of f(x)...
f(x)=-x²+3x+8
f'(x)=-2x+3
Set f'(x) equal to 0...
0=-2x+3
-3=-2x
3/2=x
This means that the x-value of our turning point is 3/2. Now we need to analyze the equation to figure out the end behavior of this graph as x approaches infinity and negative infinity.
Since the leading coefficient is -1, as x approaches ∞, f(x) approaches -∞ Because the exponent of the leading term is even, the end behavior of f(x) as x approaches -∞ is also -∞.
This means that the interval by which this parabola is increasing is...
(-∞,3/2)
PLEASE DON'T include 3/2 on the increasing interval because it's a turning point. The slope of the tangent line to the turning point is 0 so the graph isn't increasing OR decreasing at this point.
I really hope this helps!
Best wishes :)
