Polynomials are the expressions that contain two or more algebra terms - constants, variables and their powers of a particular variable. The simple example of a polynomial is
In the given question,
<span>9x3 – 4.1x2 + 7.3 is the polynomial because it has different powers of same variable x and does not contain any other variable.</span>
T(t) = Ts + (T₀ - Ts)exp(-kt), substituting the values:
60 = 50 + (80 - 50)exp(-25k)
10/30 = exp(-25k)
k = 0.0439 °C/min
Answer:
120 mg
Step-by-step explanation:
750 ml 300mg
300 ml x mg
750 / 300 = 300 / x
x = (300 x 300) / 750 = 120 mg
"lbs" (pounds) is a measure of force, whereas "kgs" (kilograms) is
a measure of mass. Being different units with different physical
dimensions, they can never be 'equal'.
-- 47 lbs is the weight of 64.9 kgs of mass on Mars.
-- 47 lbs is the weight of 128.8 kgs of mass on the Moon.
-- 47 lbs is the weight of 21.3 kgs of mass on Earth.

Answer: choice D
----------------------------------------------
Work Shown:
I'm assuming the problem is -4*(1-x) <= -12+2x where the first term is -4 and not 4
-4*(1-x) <= -12+2x
-4*(1-x) <= -12+2x
-4+4x <= -12+2x
-4+4x-2x <= -12+2x-2x
-4+2x <= -12
-4+2x+4 <= -12+4
2x <= -8
2x/2 <= -8/2
x <= -4
To graph x <= -4, you plot a closed circle at -4. Then you shade to the left of the closed circle. This matches with choice D
