Answer:
Step-by-step explanation:
the nearest 10 thousandth position is 7. So rounded to the nearest 10000 would by 70000.
Why?
Because the 1 is less than 5 and that does does not alter the 7 in any way.
50 is the answer to this question
A = L * W
A = 54
L = 2W + 3
54 = W(2W + 3)
54 = 2W^2 + 3W
2W^2 + 3W - 54 = 0
(2W - 9)(W + 6) = 0
2W - 9 = 0
2W = 9
W = 9/2
W = 4.5 <== width
W + 6 = 0
W = -6....it wont be this one because it is negative
L = 2W + 3
L = 2(4.5) + 3
L = 9 + 3
L = 12 <==length
Answer:
$568.75
Step-by-step explanation:
Serenitys salary s is given by the equation:
s = 300 + 0.25*x
In case of x = 1075:
s = 300 + 0.25*1075 = 568.75
1) Take natural logarithms (Ln) on both sides of the first equation:
f(t) = 18 [0.887]^t => Ln [f(t) ] = Ln (18) + t Ln(0.887)
2) Take natural lograrithms (Ln) on both sides of the second equation:
f(t) = Qo [e] ^ (-kt) => Ln [f(t) ] = Ln(Qo) - kt
3) Make the coefficients equal=>
Ln (Qo) = Ln(18) => Qo = 18
Ln (0.887) = - k => -k = -0.1199
4) Substitute the terms in f(t) = Qo [e]^ (-kt) =>
f(t) = 18 [e]^ ( -0.1199 t)
Answer: 18 [e]^(- 0.1199t)
