The y-intercept would be 4
Step-by-step explanation:
Answer:
I believe that your answer is a
Step-by-step explanation:
I remember that the exponent would be multiplied by both sides.
Hello!
You know that two sides and one of the angles are congruent
The only choice that has two sides and 1 angle is ASA postulate
The answer is ASA postulate
Hope this helps!
#33 is 0.3 times 42, because 0.3 is basically 30%, and you always multiply the percent by the number to get the answer. It could also be 3/10 times 42.
To find the quadratic of the form ax^2+bx+c=y set up a system of equations with the points provided...
a+b+c=4, 0a+0b+c=3, a-b+c=-6 getting differences:
a+b=1, -a+b=9 and getting difference again:
2a=-8, so a=-4, making a+b=1 become:
-4+b=1, so b=5, making a+b+c=4 become:
-4+5+c=4, so c=3
thus the quadratic that produces those three points is:
y=-4x^2+5x+3
...
The vertex occurs when the velocity is equal to zero, the derivative of the quadratic...
dy/dx=-8x+5, dy/dx=0 when x=5/8=0.625
Then you can find y(5/8)=4.5625
So the vertex is (0.625, 4.5625)
Or you may wish to remember that the vertex will always be:
(-b/(2a), (4ac-b^2)/(4a)) (this can be derived from conservation of energy under constant acceleration or the vertex form of the quadratic)
The axis of symmetry will be the vertical line about the x-coordinate of the vertex, in this case:
x=0.625
