The quadratic function is given by the equation
The maximal height will be at vertex. Find t-coordinate of the parabola vertex:
At t=4,
Answer: it will take 4 seconds for the ball to reach the maximal height of 3.7 feet.
The slope of the given line is 1/3.
The perpendiculars all have the negative reciprocal slope, -3.
<span>A. y + 2 = -3(x-4)
Yes, slope -3.
B. y - 5 = 3(x+11)
No, slope 3.
C. y = -3x - 5/3
Yes, slope -3.
D. y = 1/3 x - 2
No, that's slope 1/3.
E. 3x + y = 7
</span>
That's
y = -3x + 7
Another slope -3, Yes.
X ·( x + 1 ) = 600
x² + x = 600
x² + x - 600 = 0
x = ( - 1 - 49 ) / 2 = - 50 : 2 = - 25
x = - 25, x + 1 = - 24
( - 25 ) · ( - 24 ) = 600
Answer:
C ) - 25
<h2>
Answer: 55 degrees</h2>
Step-by-step explanation:
Every triangle has 3 sides and 3 interior angles whose measures sum to 180 degrees. For example, a triangle with angles , and :
Following this rule, we will apply it to the angles XYZ, YXZ and the unknown XZY:
Finally:
