Answer:
- The degree of the polynomial is even.
- The leading coefficient is positive.
- The polynomial has four zeros.
Step-by-step explanation:
As shown at the graph
The polynomial function intersects with x-axis at 4 points and opens up.
So, we can deduce that:
1) The degree of the polynomial is the fourth degree because it have 4 points of intersection with the x-axis
So, The degree of the polynomial is even
2) As the curve opens up ⇒ The leading coefficient is positive
Leading coefficients are the numbers written in front of the variable with the largest exponent.
3) The polynomial has four zeros because it have 4 points of intersection with the x-axis
The zeros of the polynomial are the values of x at which y = 0
Answer:
A) h=0.5x+7
Step-by-step explanation:
given
initial height = 7 feet
growth rate = 6 in = 0.5 feet / year
let # of growing years = x
For a linear growth rate:
height after x years, h = initial height + (# of growing years) * (growth rate)
substiuting the values above into this equation
h = 7 feet + (x years) * (0.5 feet/year)
or
h = 7 + 0.5x (rearranging)
h = 0.5x + 7
Answer:
it means teh elephant grows 3 kilograms per month instead
Step-by-step explanation:
Answer:
(0, e-1) or (0, 1.718) to the nearest thousandth.
Step-by-step explanation:
The y-intercept occurs when x = 0 so here we have:
y = e^(1 - 0) - 1
= e - 1
So the y-intercept is the point (0, e-1)
130.47 - 108.17
