Answer:
D
Step-by-step explanation:
Given a polynomial f(x) with roots say x = a and x = b, then the factors are
(x - a) and (x - b) and f(x) is the product of the roots, that is
f(x) = (x - a)(x - b)
Here the roots are x = - 4, x = 0 and double root at x = 7
Thus factors are (x - (- 4)), (x - 0), that is (x + 4) and x
Given a double root at x = 7 the factor is (x - 7)², thus polynomial is
y = x(x + 4)(x - 7)² → D
The answer to 1. (1, -2)
The answer to 2. (-2, -2)
The answer to 3. (4, -1/2)
The answer to 4. (3, -1/2)
The answer to 5. No solution.
Answer:
120
Step-by-step explanation:
First, you want to find the third angle
to do that you 180-33+87=60
x=60
since x and y are on a straight line, to find y would be 180-x
180-60=120
y=120
It could have been oh so much easier to choose the best choice
if you had but told me what the choices are.
The most appropriate choice depends on why you want to know,
and what you plan on doing with the information. Are you going to
use it to help you decide ...
-- How many entrance gates to build ?
-- How many ticket-takers to hire ?
-- What size parking lot is needed ?
-- How much ice cream and beer to stock in the park each day ?
-- How many rest rooms the park needs ?
-- How many costumed characters should roam the park ?
-- How many police should patrol the park ?
-- How much the park needs to be advertised in the next 6 months ?
-- Whether it will pay to build another similar park somewhere else ?
Depending on the application, here are some appropriate units
to describe the rate at which people are entering a theme park:
-- visitors per minute
-- visitors per hour
-- visitors per day
-- visitors per week
-- visitors per month
-- visitors per year
Answer:
D (I think?)
Step-by-step explanation:
It's neither a nor b because neither of them would work if you plug in o for x.
The reason I think it's D and not C is because it goes up by 10,000 x (1.1)^x
Just not sure because because of how the question was asked. Hope this helps
