Answer:we have that

k² x³-6kx+9

we know that

The Remainder Theorem says: If the polynomial f(x) is divisible by a bynomial (x-a) then the number "a" is a root of the polynomial f(x)

so

x=1  is a root of the polynomial

therefore

for x=1

k² x³-6kx+9=0--------> k² (1)³-6k(1)+9=0-----> k²-6k+9=0

using a graph tool------> to resolve the second order equation

the solution is

k=3

k=3

k²-6k+9=0---------> (k-3)²=0

the answer is

k=3

Of the people who fished at Clearwater Park today, 48 had a fishing license, 32and did not. Of the people who fished at Mountain
horrorfan [7]

Answer:

The probability that the fisher chosen from Clearwater did not have a license and the fisher chosen from Mountain View had a license is 0.32.

Step-by-step explanation:

Denote the events as follows:

<em>X</em> = a fisher at Clearwater Park had a fishing license

<em>Y</em> = a fisher at Mountain View Park had a fishing license

The two events are independent.

The information provided is:

n (X) = 48

n (X') = 32

n (Y) = 72

n (Y') = 18

Then,

N (X) = n (X) + n (X')

        = 48 + 32

        = 80

N (Y) = n (Y) + n (Y')

        = 72 + 18

        = 90

Compute the probability that the fisher chosen from Clearwater did not have a license and the fisher chosen from Mountain View had a license as follows:

P(X'\cap Y)=P(X')\times P(Y)

                 =\frac{n(X')}{N(X)}\times \frac{n(Y)}{N(Y)} \\\\=\frac{32}{80}\times\frac{72}{90}\\\\=0.32

Thus, the probability that the fisher chosen from Clearwater did not have a license and the fisher chosen from Mountain View had a license is 0.32.

Duval County Landscaping uses two different sized trucks to deliver mulch. The first truck can transport x cubic yards of mulch,
Gre4nikov [31]
For this case, the first thing we must do is define variables.
 We have then:
 x: number of cubic yards of mulch that first truck can transport
 y: number of cubic yards of mulch that second truck can transport
 Now we write the expression.
 The first truck makes 12 trips to a job site:
 12x&#10;
 The second makes 14 trips:
 14y&#10;
 The difference between the first truck and the second truck is:
 12x - 14y
 Answer:
 
An expression that represents the difference in the total number of cubic yards that the first truck delivers compared to the second is:
 
12x - 14y

ALGEBRA evaluate each eapression if x= -3, y=8, and z=-12<br> y-10 <br> 12-z<br> 3-x<br> z-24
Vinvika [58]

Answer:

  • -2
  • 24
  • 6
  • -36

Step-by-step explanation:

Put the numbers in place of the corresponding letter and do the arithmetic.

  y -10 = 8 -10 = -2

  12 -z = 12 -(-12) = 24

  3 -x = 3 -(-3) = 6

  z -24 = -12 -24 = -36
