Answer and explanation:
19.is 5th degree polynomial because the the ^ is 5 witch is a degree of 5 and there is four terms so its a polynomial
20 t will equal 49 because here is my work -16(4)^2+75(4)+5= -16(16)+300+5=-256+300+5=49
now here is some stuff to remember about 19
when ever you see something like 5x^2 its a 2nd degree monomial
when you see 5x^2+5 its a second degree binomial
when you see 6x^4+3x+2 its a 4th degree trinomial
but anything over 3 terms is a polynomial of what ever degree such as ^2 ^3 or even ^5 degree
Hope i helped you learn may i please have brainliest. Please ;)
Since the question explicitly stated that ice production is proportional to time, we're going to have to use proportion fractions. Remember to convert hours into minutes as well.
f(x)=2,459(0.92)^t
Using the information given above, complete the following statements. The percent change is %. The percent change represents .
f(x)=2,459(0.92)^t
Given equation is an exponential function and in the form of f(x) = a(1-r)^x
Where 'a' is the initial population
'r' is the decay rate
'x' is the time
f(x) = a(1-r)^x
Given function is f(x)=2,459(0.92)^t
1 - r = 0.92
r = 1 - 0.92
r = 0.08
r= 0.08 %
Percentage change = 0.08%
Percentage change represents the decay rate.
Complete question :
X: 3, 4, 5, 6
f(x): .25, .55, .15, .05
Answer:
0.60
Step-by-step explanation:
Given the data:
Variance (s) :
Σx²*f(x) - E(x)²:
E(x) = (3*0.25) + (4*0.55)+(5*0.15)+(6*0.05) = 4
Σx²*f(x) - E(x)²: [(3^2 * 0.25)+(4^2 * 0.55)+(5^2 * 0.15)+(6^2 * 0.05)] - 4²
16.6 - 16 = 0.6
