if k is a constant, determine and state the value of kids such that the polynomial k^2x^3-6kx+9 divisible by x-1

Answers

Answer 1
Answer: By the polynomial remainder theorem, k^2x^3-6kx+9 will be divisible by x-1 if the value of the polynomial at x=1 is 0.

k^2(1)^3-6k(1)+9=k^2-6k+9=(k-3)^2=0

which occurs for k=3.

A nest of ants initially contains 500 individuals. The population is increasing by 12% each week.a) How many ants will be there after :
i. 10 weeks
ii. 20 weeks

b)How many weeks will it take for the ant population to reach 2000.

Answers

Answer:

a) (i) 1553 ants

(ii) 4823 ants

b) 12 weeks

Step-by-step explanation:

Given,

The initial number of ants, P = 500,

Also, the rate of increasing per week, r = 12% = 0.12,

So, the number of ants after x weeks,

A=P(1+r)^x

\implies A=500(1+0.12)^x=500(1.12)^x

a) (i) If x = 10 weeks,

The number of ants would be,

A=500(1.12)^(10)=1552.92\approx 1553

(ii) If x = 20 weeks,

The number of ants would be,

A=500(1.12)^(20)=4823.15\approx 4823

b) If A = 2000

\implies 2000 = 500(1.12)^x

4=(1.12)^x

Taking log both sides,

log(4) = xlog(1.12)

x =  12.23 ≈ 12 weeks

A)4, 823
B)13 Weeks

A: 500 (1 + .12)^x (which is 500 (1 + .12)^20 now)
= 4823. 15 which is ≈ 4823.

B: 2000/ y1 =  500 (1 + .12)^x / y2

12.23 so 13 weeks

Find all horizontal asymptotes of the following function. f(x)=(x+4)(x²+13x+36)

Answers

Answer:

To find the horizontal asymptote of the function,

we need to find the intersection points of the function with the

y-axis.

These points are the solutions of the equation

f(x) = 0.

We decompose the function in the form of the product of two expressions:

f(x) = (x + 4)(x² + 13x + 36)

Now we can set each of the expressions inside the parentheses equal to zero and solve the horizontal equations:

x + 4 = 0 or x² + 13x + 36 = 0

To solve the first equation

, we can factor out

x: x = -4

To solve the second equation, we can use the analysis method or the quadratic formula.

Using the analysis method, we can decompose the expression

x² + 13x + 36 in the following form:

(x + 4)(x + 9) = 0 So the two horizontal equations are equal to

x + 4 = 0 (that is, x = - 4) and x + 9 = 0 (that is, x = -9).

So the horizontal asymptote of the function

f(x) = (x + 4)(x² + 13x + 36) is equal to

x = -4 and x = -9.

Final answer:

The horizontal asymptote of the function f(x) = (x+4)(x²+13x+36) is y = x³.

Explanation:

The function given is f(x) = (x+4)(x²+13x+36). To find the horizontal asymptotes, we need to determine the behavior of the function as x approaches positive and negative infinity.

As x approaches positive or negative infinity, the function behaves like the highest power term in the expression. In this case, the highest power term is x³, so the horizontal asymptote is y = x³.

Therefore, the horizontal asymptote of the function is y = x³.
