-5x^2(small two at top ) +9
The correct answers are A, D, and E.
Answer:
a) The vertex of the graph is , b) , c) The equation of the parabola is .
Step-by-step explanation:
a) The tennis ball experiments a free fall, that is, an uniform accelerated motion due to gravity and in which effects from Earth's rotation and air viscocity are negligible. The height of the ball in time is represented by a second order polynomial. Hence, the vertex of the parabola is the initial point highlighted in graph.
The vertex of the graph is .
b) If we know that , and , then the value of is:
c) The equation of the parabola is .
Answer:
-2/3
Step-by-step explanation:
To find the slope we use the formula
m= ( y2-y1)/(x2-x1)
= ( 14-10)/(-18- -12)
= (14-10)/(-18+12)
= 4/-6
= -2/3
Answer: 15 Length and 9 width or 9length and 15 width
Step-by-step explanation:
Find the factors of 135
Then you see 9 and 15
And 15-9=6 which means that those numbers are the correct ones.
