Step-by-step explanation:
Answer:
The left end goes up and the right end goes down.
Step-by-step explanation:
Lets solve the function first and then find out the end behavior of the polynomial:
The given function is f(x)=-x^3+x^2-4x+2
First step is: Identify the degree of the polynomial. For this we have to find out the variable with the largest exponent.
The variable with the largest exponent in the given function is -x³
The degree of the polynomial is the largest exponent on the variable.
3 is the degree of the polynomial.
Since the degree is Odd, the ends of the function will point in the opposite direction.
Now find out the leading coefficient of the polynomial which is -1.
Since the leading coefficient is negative the graph falls to the right.
To find the behavior we have to use the degree of the polynomial as well as the sign of leading coefficient.
If it is ODD and NEGATIVE then the the left end goes up and the right end goes down.
Therefore the end behavior of the given function will be described as "the the left end goes up and the right end goes down"....
Remember that the formula for the surface area of a sphere is
. Substitute the given surface area to solve:
. Divide by 4 on both sides:
. Divide by pi on both sides:
. Square root on both sides to find the radius:
Answer:
feet/million year
Step-by-step explanation:
We are given that
Elevation of top of basalt in valley =4100 feet
Elevation of bottom of basalt in valley =2100 feet
Age of top of basalt in valley=15000 years
Age of bottom of basalt in valley=1.2 million years=
We have to find the rate of basalt filling in the valley in feet per million yeas
Rate of basalt filling in the valley=
Rate of basalt filling in the valley=
Rate of basalt filling in the valley=
feet/million year
Answer:
The width is - 4 the lengeth is - 7
Step-by-step explanation:
w*l = 28in²
w = ?
l = w+3
w=2
2+3 = 5
5*2 = 10
w = 3
3+3 = 6
6*3 = 18
w = 4
4+3 = 7
7*4 = 28
So,
W = 4 L = 7
