Option C is the correct choice $-2x^4+4x^2+3x-2$ ,

Remainder of a polynomial by substitution

For a polynomial f(x) to give a remainder of 24 when divided by x + 2:

f(-2) = 24

By testing, substitute x = -2 into the equation $-2x^4+4x^2+3x-2$

$f(x) = -2x^3+4x^2+3x-2\\\\f(-2)=-2(-2)^3+4(-2)^2+3(-2)-2\\\\f(-2)=-2(-8)+4(4)-6-2\\\\f(-2)=16+16-8\\\\f(-2)=32-8\\\\f(-2)=24$

Since f(-2) = 24 when x = -2 is substituted into $-2x^4+4x^2+3x-2$ , then $-2x^4+4x^2+3x-2$ has a remainder of 24 when divided by x+2

Which of the following graphs shows the solution for the inequality<br> y-4> 2(x+2)?

timofeeve [1]

Answer:

Answer:

Graph C shows the solution for the inequality

Step-by-step explanation:

y - 4 > 2(x + 2)

y > 2x + 4 + 4

y > 2x + 8

Let y = 2x + 8, Then

X-intercept (0, 8)

Y-intercept (-4, 0)

Since the inequality sign is > we use broken line.

Put, (0, 0)

y > 2x + 8

0 > 0+ 8

0 > 8 Which is false

so, the answer will be above the broken line

Hence , Graph C shows inequality

What is the missing reason in the proof?

IrinaVladis [17]

We can identify that the missing reason in the proof is: Definition of Congruent angles.

<h3>How to give proof of a congruent triangle?</h3>

We know that an angle measure of 90° of ∠ABC in the triangle means that it is a right angle triangle.

We also see that ∠ADB is also a right angle and is equal to 90°.

Now, since they have exactly the same measure, these angles are congruent. Then we can say that the angles are congruent and as such:

∠ABC ≅ ∠ABD

Thus, we can identify that the missing reason is: Definition of Congruent angles.

Freddie is at chess practice waiting on his opponent's next move. He notices that the 4-inch-long minute hand is rotating around

Alex777 [14]

One complete revolution of the minute hand sweeps a central angle of 360° which is equivalent to 60 minutes.
That is, the minute hand creates
(360°/(60 min) = 6 degrees/min.

From 3:35 to 3:55 is 20 minutes.
It sweeps a central angle of
(20 min)*(6 deg/min) = 120°

Because 360° = 2π radians,
120° = (120/360)*2π = (2π)/3 radians

Answer:
$\frac{2 \pi }{3} \,radians$
In decimals, this is 2.1 radians (nearest tenth)

Part 2:
Because the minute hand is 4 inches long, the length of the arc swept is
(4 in)*(2π/3 radians) = 8π/3 inches

Answer:
$\frac{8 \pi }{3} \,inches$
In decimals, this is 8.4 inches (nearest tenth).

By convention, the independent variable is arrayed along the ____ in a scattergram. regression line calibration line vertical ax

babunello [35]

Answer:

Horizontal axis

Step-by-step explanation:

By convention, the independent variables is arrayed along the Horizontal axis (abscissa) in a scattergram.

The stcattergram has two dimensions

The X (independent) variable is arrayed along the horizontal axis.
The Y(dependent) variable is arrayed along the vertical axis.
Each dot scattergram is case in data set.
The dot is placed at the intersection cases scores on X and Y.

Y\7+6= what does y =

choli [55]

Simple, y can be anything. Because you have no other variable on the other side to use; y can be whatever you want to plug-in to the equation.
