Its an ellipse.
3 (x+7)^2+2 (y-2)^2-6 = 0
Answer:
26.5 units
Step-by-step explanation:
The height of the ball at any time t is given by :
...(1)
We need to find the maximum height of the ball.
For maximum height, put 
i.e.
Put t = 1.25 in equation (1) to find the maximum height.
So,
So, the maximum height reached by the ball is 26.5 units.
Answer:a=130,b=50
Step-by-step explanation:
a+b= 180
2a-5b=10
2(180-b)-5b=10 (I have substituted (180-b) for a here.)
360-2b-5b=10
350=7b
b=50
a+50=180
a=130
Answer:
He had 534.45 more in credits that debits
Step-by-step explanation:
Ignatius hd $534.45 more in credits than in debits. Since Ignatius had an initial balance of $124.82 at the beginning of the month and ended the month with $659.27 he was up money versus what he had in his account at the beginning of the month. During the month Ignatius made money that was credited to his account so that he ended it with a higher balance.
Answer: C.) 1.12 seconds
Step-by-step explanation:
Hi, to answer this question we have to substitute h=0 (when the rock hits the ground the height above it is 0) in the equation given:
h (t) = –16t2 + 20
Solving for t (time)
0= –16t2 + 20
16t2=20
t2=20/16
t=√1.25 =1.12 seconds (option C)
