Given:

The function is

[tex]f(x)=2x^2+kx-9[/tex]

The remainder when f(x) is divided by x+6 is 57.

To find:

The value of k.

Solution:

According to the remainder theorem, if a polynomial function f(x) is divided by (x-a), then f(a) is the remainder.

The remainder when f(x) is divided by x+6 is 57.

Using remainder theorem, we get f(-6)=57.

Putting x=-6 in the given function.

[tex]f(-6)=2(-6)^2+k(-6)-9[/tex]

[tex]57=2(36)-6k-9[/tex]

[tex]57=72-6k-9[/tex]

[tex]57=63-6k[/tex]

On further simplification, we get

[tex]6k=63-57[/tex]

[tex]6k=6[/tex]

[tex]k=\dfrac{6}{6}[/tex]

[tex]k=1[/tex]

Therefore, the value of k is 1.

Answer:

28.4in³

Step-by-step explanation:

Volume of the square based pyramid = L²H/3 where;

L is the length of a side of the square base

H is the height of the prism

Given

Perimeter of the base = 13.4 in

Height of the pyramid = 7.6in

First we need to get the length of the square base

Perimeter of a square = 4L

13.4 = 4L

L = 13.4/4

L = 3.35 in

Next is to find the required volume of the pyramid

V = L²H/3

V =  3.35²(7.6)/3

V = 85.291/3

V =  28.4 in³

Hence the volume of the pyramid to nearest tenth is 28.4in³

Answer:

2208 is how many workers total

Step-by-step explanation:

Ima only give one way bc I only know one lol so what you do is you multiply 1380 by 60% which is 828 and then you add that to 1380 and you get 2208

Answer:

Mean = 5.2

Mode = 7

Median =  6

Range = 7

Step-by-step explanation:

Mean is all 10 numbers added up divided by 10

Mode is 7 s it is the most common integer

Median is 6 as it is the middle number between 5 and 7 and 7+5/2 = 6

Range is 7 as 8-1 is 7

Hope this helps :)

Answer:

$112

Step-by-step explanation:

$168 per 12 hours of work

168/12 = 14

$14 per hour of work

14*8 = 112

$112 per 8 hours of work

I hope that this helped

168/12=14 . 14•8= 112

i am pretty sure this is the answer

Answer:

Step-by-step explanation:

Answer:

x = -y + 3

y = -x + 3

In standard form, it would be 2x + 2y = 6

Answer:

they would both be 61°

Step-by-step explanation:

when the angles make out a straight line it equals to 180 and 180 subtracted to 119 comes out to 61 and both b and c are vertical angles which would make them congruent

Answer:

B= 61 C=61

Step-by-step explanation:

You can see how there is a straight line (180 degrees) so if you do 180-119 you get 61 degrees

Answer:

3

Step-by-step explanation:

17 + 1 = 18

18/6 = 3

Answer:

Below in bold.

Step-by-step explanation:

The angles on the line AC add up to 180 degrees, so:

11x - 8 + 90 + 6x + 2 + 4x + 12 = 180

21x + 96 = 180

21x = 180 - 96 = 84

x = 84/21

x = 4.

<ABD = 11(4) - 8 = 36 degrees.

<EBF = 6(4) + 2 = 26 degrees.

<CBF =  4(4) + 12 = 28 degrees.

The solution to this given system of equations is (x,y) = (0.4,15).

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

y - 13 = 5x

y - 5x = 12

Now,

To do this, we can add both equations together to eliminate x:

(y - 13) + (y - 5x) = 5x + 12 2y - 13 - 5x = 17 2y = 30 y = 15

Now that we have found y, we can substitute it into either equation to find x. For example:

15 - 13 = 5x 2 = 5x x = 0.4

Therefore, by the given system of equations the answer will be (x,y) = (0.4,15).
