Answer:
f(x) = 3(0.2)^x
Step-by-step explanation:
The leading coefficient is 3 as x = 0 gives f(x) = 3.
When x = 1, f(x) = 0.6. so try :
0.6 =3(1.2)^1 = 3.6 so it's not the fiirst choice.
0.6 = 3(0.2)^1 = 0.6 so its last choice.
Check when x = -1:
3(0.2)^-1
= 3/ 0.2
= 15
The answer is D, because that is what you should get when you multiply it out.
4x^2 times x^2 = 4x^4 because...
1) multiply the 4 and the one in front of the x on the second term = 4 then
2) multiply x^2 times x^2 to get x^4, not x^3, so you can immediately eliminate A and B to save time.
Now let's deal with the second part..."may or may not be" part
A polynomial is an expression with more than two algebraic terms
terms are like...
2x + 3y ---there's two terms there, eventhough the 2 and x are multiplied, it doesn't count (same with the 3 and y)
since it only have two terms, not more than two terms, it is called a binomial, not polynomial. I think that's what they mean by that
one term with a variable (y,x,and so on) is called a monomial
one term with no var is called a constant
there's many more but hope this gave you some help
So volue of a cone=1/3 times (area of base[which is a circle]) times height
area of base=area of circle=pi time radius^2
area=pi times 5^2
area=pi times 25=25pi
1/3 times 25pi times 18
25pi times 18 times 1/3
25pi times 18/3
25pi times 6=150pi
the answer is 150π in^3 or 150π cubic inches or C
( to solve, aprox pi to 3.141592 an multiply 150 by 3.141592=471.239 in^3)
Answer:
frist it goes by a train
Step-by-step explanation:
2=2=2=444=11111111
Inflection at f'(x) = 0
<span>
x^1/2 / (1 + x + x^3) = 0 </span>
<span>The x coordinate is x = 0 </span>
<span>
or "C" from your choices there. </span>
<span>The simplest way is to notice that this happens when x = 0. The reason is you got: </span>
<span>
x^1/2 / (some expression) </span>
<span>
at x = 0 the numerator is 0 so unless the denominator is also 0 the result is 0. </span>
<span>
The denominator for x = 0 is 1 so you get </span>
<span>
0/1 = 0.
