Answer:
43.06 ft
3.20 seconds
Step-by-step explanation:
h = -16t^2 +50t +4
The maximum is at the vertex
The x coordinate for the vertex is a the axis of symmetry
The axis of symmetry is
h=-b/2a when the equation is at^2 +bt+c
h = -50/2(-16)
=-50/-32
= 1.5625
The maximum is when x is at 1.5625
to find y we put this into the equation
h = -16(1.5623)^2 + 50(1.5625) +4
= -16(2.44140625) + 78.125+4
= -39.0625+78.125+4
=43.0625
To the nearest hundredth
43.06 ft
The second part is to find when it hits the ground, or when h=0
0 = -16t^2 +50t +4
Using the quadratic formula
-b±sqrt(b^2 -4ac)
------------------------
2a
-50±sqrt(50^2 -4*-16*4)
------------------------
2*-16
-50±sqrt(2500 +256)
------------------------
-32
-50±sqrt(2756)
------------------------
-32
-50 + sqrt(2756) or -50 + sqrt(2756)
----------------------- -----------------------
-32 -32
-.078 3.20
Since time cannot be negative
3.20 seconds

Answer:
risk
Step-by-step explanation:
Lenders rely on credit scores to determine risk.
The percentage of 37% of the sum of the numbers 27.6 and 15.9 will be
The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
The first method →
Find the sum of two numbers,
27.6 + 15.9 = 43.5
37% of 43.5 will be as,
0.37 x 43.5 = 16.095
The second method →
Find the 37% of 27.6 as
0.37 x 27.6 = 10.212
Find the 37% of 15.9 as
0.37 x 15.9 = 5.883
Add both numbers as
10.212 + 5.883 = 16.095
The easiest method is method 1 because it is fewer in steps.
Hence "The percentage of 37% of the sum of the numbers 27.6 and 15.9 will be 16.095.
