The formula is
I=prt
I interest earned 200
P principle 2500
R interest rate 0.04
T time ?
We need to solve for t
T=I÷pr
T=200÷(2,500×0.04)
T=2years
Hope it helps
Answer:
I was not sure to what decimal point to round it to
a) Fraction: 2/7 Decimal: 0.28571 Percent: 28.571 %
b) Fraction: 5/7 Decimal: 0.71428 Percent: 71.428 %
c) Fraction: 1/7 Decimal: 0.14285 Percent: 14.285 %
<span>if you multiply 1/8 by 4, the fraction become 4/32, and if you multiply 1/4 by 8 you get 8/32.Since both fractions have the same denominator, we can find which fraction has the greater value. Since 1/4(8/32) has a greater numerator, the 1 pound of lead will have a larger value.</span>
Answer:
c
Step-by-step explanation:
We can write this as:-
P(x) = + x^3 - 5x^2 - 25x + 125
There are 2 changes of real sign so by Descartes Rule of signs there are either 2 positive real roots or 0 positive roots.
P(-x) = - x^3 - 5x^2 + 25x + 125
There is just one change of sign so there is exactly 1 real negative root.
125 is a multiple of 5 so By rational root theorem 5 could be a positive root.
P(5) = 125 - 125 - 125 + 125 = 0 so one zero is 5
if we divide the polynomial by (x - 5) we get the quadratic
x^2 - 25
(x + 5)(x - 5) = 0
x = 5,-5
so the roots are 5 (multiplicity 2) and -5.
2 real positive zeroes and one real negative zero
