Answer:

cubic polynomial

Step-by-step explanation:

Given polynomial is $h(x)=-6x^{3}+2x-5$

A polynomial of degree 1 is a linear polynomial.

A polynomial of degree 2 is a quadratic polynomial.

A polynomial of degree 3 is a cubic polynomial.

In this case the exponent with the maximum value in the polynomial is 3.

Hence the degree of the polynomial h(x) is 3.

Hence the given polynomial is a cubic polynomial.

Suppose the population of a town was 40,000 on January 1, 2010 and was 50,000 on January 1, 2015. Let P(t) be the population of

Lorico [155]

Answer:

Given,

The initial population ( on 2010 ) = 40,000,

Let r be the rate of increasing population per year,

Thus, the function that shows the population after t years,

$P(x)=40000(1+r)^t$

And, the population after 5 years ( on 2015 ) is,

$P(5)=40000(1+r)^{5}$

According to the question,

P(5) = 50,000,

$\implies 40000(1+r)^5=50000$

$(1+r)^5=\frac{50000}{40000}=1.25$

$r + 1= 1.04563955259$

$\implies r = 0.04653955259\approx 0.04654$

So, the population is increasing the with rate of 0.04654,

And, the population after t years would be,

$P(t)=40000(1+0.04654)^t$

$\implies 40000(1.04654)^t$

Since, the exponential function is,

$f(x) = ab^x$

Hence, by comparing,

a = 40000,

b = 1.04654

CAN SOMEBODY HELP ME PLZ

laiz [17]

Let x be the brick portion of the wall
Since x is 2/3 of the wall
Then x= (2/3)(2 3/4)
x= 11/6 = 1 5/6
So the brick portion of the wall is 1 5/6 feet

Note: that's not 15/6, it's a mixed fraction which is 1 + 5/6.. just to let you know
