It is given that x is 5 less than the quotient of y and 3.
And given value of y is 18 .
So quotient of y and 3 is

And 5 less than 6 =1
So we have y=18 and x=1
Given expression is

At x=1 and y=18, we will get


Step-by-step explanation:
We have,
A ball is thrown into the air with an upward velocity of 36 ft/s. Its height h in feet after t seconds is given by the function :
......(1)
Part (a) :
The maximum height reached by the ball is given by :

Part (b) :
The maximum height of the ball is calculated by putting t = 1.125 in equation (1) such that :

Answer:
0,-14
Step-by-step explanation:
5(x+7)²=245
divide both sides by 5
(x+7)²=49
Taking the square root of both sides
x+7=±7
Either x+7=7
subtract 7 from both sides
x+7-7=7-7
x=0
or
x+7=-7
subtract 7 from both sides
x+7-7=-7-7
x=-14
Mean: [45+65+30+50+20+30]/6 = 40.2
Median
First order the number {20, 30, 30,45, 50, 50}
The median is the average of the two values in the middle of the list: (30+45)/2 = 37.5
Mode: 30 and 50 (they are repeated the same number of times)
