Step-by-step explanation:
the leading coefficient means the coefficient (factor) of the term with the highest exponent of the variable (typically x).
with sufficiently large values of this variable (x - going far enough to the right) this term will "win" in value against any other term of the polynomial expression.
and therefore the sign of its factor (coefficient) will determine, if the curve will go up or down.
a positive factor (coefficient) will make the value of this term and therefore of the whole polynomial larger and larger, making the curve going up to +infinity.
a negative factor (coefficient) will make the value of this term and therefore of the whole polynomial smaller and smaller (more negative and more negative), making the curve going down to -infinity.
Answer:
option-A
Step-by-step explanation:
For company-1:
d=3m+5
so, the rate of change =3
For company-2:
we can find rate of change
rate of change is


now, we can use point slope form of line
y1=12 , x1=0


We can see that
rate of change of first company(3) is greater than rate of change of second company(1)
Answer:
$3.50/donut
Step-by-step explanation:
Since Rosena bought an 8-pack of donuts for $28.00, we can say that the price of $28.00 corresponds with this pack.
The unit rate represents the price per donut, assuming a constant proportion.
The pack that Rosena bought contains 8 donuts. Therefore, to find the price of one donut, divide the price that corresponds with the 8-donut pack by 8, because
.
The price of the 8-pack of donuts was
. Diving by 8, we have:
Therefore, the unit rate for the donuts is $3.50/donut.
2.125*10^4 x 10^4 / 1.25 x 10^3
= (2.125 / 1.25) x 10^(4 - 3)
= 1.7 x 10^1
= 17
Answer
17 times greater
