PV=FV/(1+i)^t
FV=7000, i=3.5%=0.035,t=9
put everything in the formula
PV=7000/(1+0.035)^9
PV=$5136.12
Answer:
$31.44
Step-by-step explanation:
29.95 * .05 = 1.49
29.95 + 1.49= 31.44 (you add because its tax)
hope this helps! :)
90 + 50 = 140
140 - 7 = 133
130 - 140
The domain is actually the x value of the function, so we need to find the value of x
suppose the width is x, the length is then 3x+5
the area is 50^2 inches, so x(3x+5)=50 => 3x^2+5x-50=0
Factor this quadratic equation: (x-5)(3x+10)=0 =>x=5 or x=-10/3
width can not be negative, so the width is 5
the domain is x=5
Answer:
B
Step-by-step explanation:
First, subtract 3 by the numbers
-8 > 4x > 4
Remember to flip the inequality signs
Second, divide all the numbers by 4
-2 < x < 1
Flip the inequality signs again
-2 > x > 1
I am not very experienced with these problems so I might be wrong.
