59.99 - 59.99 x saving rate = 42.89
with saving rate = r%
59.99 - 59.99 x r% = 42.89
so 59,99 ( 1 - r%) = 42.89
1 - r% = 42.89 : 59.99
1 - r% = 0,7150
r% = 1 - 0,7150
r = 28,5%
Can u put a picture of the problem
Answer:
(5y−1)(y+1)
Step-by-step explanation:
Answer:
A) =0
B)t= 0.45 seconds or t= 3.5 seconds
<em>If time is greater than 0.45 seconds then ball will reach height 12m and higher.</em>
Step-by-step explanation:
Given Equation:
h(t)= ------------------------------(Equation 1)
a) Equation to tell if ball reaches height of 12m . for that :
h= 12m
put in Equation 1.
12 =
or =12
or -12 = 0
=0
or = 0 -----------------------------------(Equation 2)
<em>This Equation tells if ball reaches height of 12m</em>
b) Does ball reaches height of 12m :
For that, the value of time can be found out from the equation above,
= 0
It can be solved using the quadratic formula:
t= 0.45 seconds or t= 3.5 seconds
If time is greater than 0.45 seconds then ball will reach height 12m and higher.
Answer:
3 2/3ft²
Step-by-step explanation:
Area of a rectangle = Length × Width
Given
Length = 5 1/2 foot
Width = 2/3foot
Substitute
Area of the rectangle = 5 1/2 × 2/3
Area of the rectangle = 11/2×2/3
Area of the rectangle = 22/6
Area of the rectangle = 11/3
Area of the rectangle = 3 2/3ft²
