Answer:
$1781.53
Step-by-step explanation:
Simple Interest Rate Formula: A = P(1 + r)ⁿ
Step 1: Define variables
Principle amount <em>P </em>= 1500
Rate <em>r</em> = 0.035
Years <em>n</em> = 5
Step 2: Substitute and Evaluate for A
A = 1500(1 + 0.035)⁵
A = 1500(1.035)⁵
A = 1500(1.18769)
A = 1781.53
The more reasonable temperature is 30°F
7 grams. 1,000 mg is equivalent to one gram.
To find the root, replace y with 0
X^2-12x+35=0
A=1 B=-12 C=35
B^2-4ac=(-12)^2 -4(1)(35)
=144 -140
=4
x=(-b+/- square root of b^2 -4ac) /over/ (2a)
Plug in the numbers
x=-(-12) sqr (-12)^2 4(1)(35) / (2)(1)
X=12 +/-sqr 4 / 2
Positive outcome
x=12 + sqr 4 / 2
x=12+2/2
x=7 <— this one
Negative outcome
x=12-2i/2
x=6-i
