Answer:
Rose has greater total amount of money than Dennis by $230.8 .
Step-by-step explanation:
Formula
Amount = Principle + Simple interest
As given
Rose and Dennis each open a savings account at the same time.
Rose invests $2,600 in an account yielding 4.1% simple interest for 9 years .
Put all the values in the formula
Simple interest = $959.4
Thus
Amount = $2600 + $959.4
Amount = $ 3559.4
Thus total amount in the Rose saving account is $3559.4 .
As given
Dennis invests $2200 in an account yielding 5.7% simple interest for 9 years .
Put all the values in the formula
Simple interest = $1128.6
Thus
Amount = 2200 + 1128.6
Amount = $ 3328.6
Thus total amount in the Dennis saving account is $ 3328.6 .
As clearly Rose has greater amount of money as compared to Dennis .
Greater amount Rose has = Amount in the Rose saving account - Amount in the Dennis saving account .
Put values in the above
Greater amount Rose has in saving account = $3559.4 - $3328.6
= $ 230.8
Therefore the Rose has greater total amount of money than Dennis by $230.8 .
The given equation is in the form ax^2 + bx + c = 0, where
a = 2
b = -12
c = 18
Those a,b,c values are plugged into the discriminant formula below
d = b^2 - 4ac
d = (-12)^2 - 4(2)(18)
d = 144 - 144
d = 0
The discriminant is zero, so there is only one real root. This root is specifically a rational number.
Answer: The smallest zero is -3.
Step-by-step explanation:
Zeros of a function are the values of input for which the function gives 0 output.
Here, the given function is,
p(x) = x(x-5)(x-2)(x+3)
For finding the zeroes of p(x),
p(x) = 0
⇒ x(x-5)(x-2)(x+3) = 0,
⇒ x = 0 or x - 5 = 0 or x-2=0 or x+3=0
⇒ x = 0 or x = 5 or x = 2 or x = -3
Thus, the zeros of the given function are 0, 5, 2, -3
In which -3 is smallest.
-2/3x=-468/17
