Answer:

B

Step-by-step explanation:

The value of the polynomial for x = 3 is the value of P(3)

P(3) = 2(3)³ - 7(3)² + 7(3) - 12 = 54 - 63 + 21 - 12 = 0 → B

Answer:

x=4, y=5. (4, 5).

Step-by-step explanation:

y=2x-3

y=-x+9

----------

2x-3=-x+9

2x-(-x)-3=9

2x+x=9+3

3x=12

x=12/3

x=4

y=2(4)-3=8-3=5

Given:

The function is

[tex]y=\tan x[/tex]

To find:

The domain of the given function.

Solution:

We know that, domain is the set of x-values or input values.

We have,

[tex]y=\tan x[/tex]

[tex]y=\dfrac{\sin x}{\cos x}[/tex]

The functions sin x and cos x are defined for all real values of x. So, the function tan x is defined for all real values of x except those value for which cos x = 0.

So, domain is [tex]-\infty<x<\infty, x\neq \dfrac{\pi}{2}+n\pi[/tex].

Note: All options are incorrect.

Answer:

C

Step-by-step explanation:

all x≠pi/2+pi n

Answer:

-33 and -21

Step-by-step explanation:

-36, -33, -30, -27, -24, -21, -18

-36

-36 + 3 = -33

-33 + 3 = -30

-30 + 3 = -27

-27 + 3 = -24

-24 + 3 = -21

-21 + 3 = -18

Answer:

6 x 4 = 24 x $2 = $48

Step-by-step explanation:

The total cost of the rectangular frame is C = $240.

A rectangle is a two-dimensional shape in which the opposite sides are parallel and equal to each other and all four angles are right angles.

Given that, a painting measures 4 by 6 inches, the framing material costs $2 per inch,

We need to find the total cost of framing material

The perimeter is given by:

P = 2x(L + W)

In this case, we know that the frame is 6 inches by 14 inches, then the perimeter will be:

P = 2x(6in + 14in)

P = 2x20in = 40in

Since, the framing material costs $6 per inch, then the total cost of the frame will be:

cost = 40x$6 = $240

Answer:

S(n) = 12,000(–0.05)n

Step-by-step explanation:

The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]

Original population , P  =  12000

Rate of decline, r = 5%

r  =  5/100

r  = 0.05

The number of years = n

The population of students after n years will be given by the formula:

[tex]S =P(1-r)^n[/tex]

Substitute r = 0.05 and P = 12000 into the formula above

[tex]S=12000(1-0.05)^n\\\\S=12000(0.95)^n[/tex]

The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]

Answer:

x = 119, y =  55

Answer:

x = 119°

y = 55°

Step-by-step explanation:

y + 125 = 180         {linear pair}

       y   = 180 - 125

       y = 55°

Sum of all the angles of quadrilateral = 360

x + 55 + 72 +114 = 360

               x + 241 = 360

                         x = 360 - 241

                        x = 119°

Answer:

Step-by-step explanation:

I just want to tell you what a term is because your going to really need it when you go into middle school. So a term is where there is a number or a a number with a variable with it or a variable by itself. For example if there is 4x + 6m + 3 + X you would have 4 terms because you have 4 numbers along with variables and a variable by itself and with some numbers which are Co -Efficient. Co-Efficient is when a number is with a variable the number along with the variable is called a Co-Efficient. Both of them together is called a term so now you know :) The whole equation is called an expression if a a number is by itself like 4 + 3m the 4 would be considered as a constant because its just a normal number standing by itself.

Answer:

is this what you mean or something else?

Answer:

96°

Step-by-step explanation:

Ratio of angles :

3 : 4 : 8

Sum of angles in a triangle = 180°

The value of the largest angle = angle with the largest ratio

This is the value of the angle with ratio 8

Sum of ratio : (3 + 4 + 8) = 15

Hence,

(8 / 15) * 180°

(8 * 180°) / 15

1440 / 15

= 96°
