Make a sketch of a fourth degree polynomial function with two complex roots and two real roots​

Answers

I cannot really graph it but I will try my best to explain.

When you have a coordinate plane draw from right to left, up to down.

Now starting from righthand top corner, draw a smooth curve just like how you will draw a quadratic equation, through the x axis then curve back making the graph touch the axis at 2 points. That's the 2 real roots

Now make another curve down but this time not touching the x axis and then curving back up to the top left corner, this meant the 2 complex roots.

This is not the only way to do it, as long as one complete curve is not touching the x axis and another complete curve, weather as a whole or combined is touching the x axis at 2 points, it has 2 real and complex roots.

PLEASE HELP!!!!!! ILL GIVE BRAINLIEST *EXTRA 40 POINTS** !! DONT SKIP :((

Answers

Answer:

Yes

Step-by-step explanation:

So we substitute the point given x=-5 and y = -3 to see if this solves both equations at the same time so

3(-5) - 9(-3) = 12 ->  -15+27 = 12 -> 12 = 12 [this one works]

8(-5) - 14 (-3) = 2 -> -40 + 42 = 2 -> 2=2 [this one works also]

Since (-5,-3) is a solution to both equations, then this is a solution to this system

Answer: Yes

Step-by-step explanation:

Here

x = -5

y = -3

3x - 9y = 12

Here if you substitute x and y,

3 * (-5) - 9 * (-3)

(-15) - (-27)

=12

8x - 14y = 2

8 * (-5) - 14 * (-3)

(-40) - (-42)

= 2

3x/5 - 2 = x + 1/3
Solve the equation above for x.

The answer is x=-35/6

By dropping a perpendicular from the top of the isosceles triangle to the base and using the Pythagorean Theorem we quickly determine that the height of the triangle is 4.

Therefore the area of the isosceles triangle is

6•4/2=12

However, we can split the isosceles triangle into three separate triangles indicated by the red lines in the diagram below. Because the radius always meets a tangent at a right angle the area of each triangle will be the length of the side multiplied by the radius of the circle. So the total area of the isosceles triangle is given by

6r/2+2•5r/2=8r=12
8r=12
r=12/8
r=3/2

When you solve the system shown by the elimination method, which statement is true?
y + 3x = 10
−y − 3x = 10

Answers

Answer:

B. There is no solution; x and y are eliminated and you get the false statement 0 = 20.

Step-by-step explanation:

According to the elimination method, the two equations are

y + 3x = 10

−y − 3x = 10

If we solve it

0 = 20

As x and y would be eliminated due to positive and negative signs

Therefore the option b is correct

Step-by-step explanation:

The director of a customer service center wants to estimate the mean number of customer calls the center handles each day, so he randomly samples 29 different days and records the number of calls each day. The sample yields a mean of 279.4 calls with a standard deviation of 25.1 calls per day. He can be 99% confident that the mean number of calls per day is between 266.5 and ________. (Round your answer to 1 decimal place.)

Answers

Answer:

He can be 99% confident that the mean number of calls per day is between 266.5 and 292.3.

Step-by-step explanation:

Confidence interval:

A confidence interval is symmetric, which means that the difference between the sample mean and the lower bound is the same as the difference between the upper bound and the sample mean.

In this question:

Sample mean: 279.4 calls

Lower bound: 266.5 calls

Upper bound: x calls

Due to the symmetry of the confidence interval:

[tex]x - 279.4 = 279.4 - 266.5[/tex]

[tex]x = 12.9 + 279.4[/tex]

[tex]x = 292.3[/tex]

So

He can be 99% confident that the mean number of calls per day is between 266.5 and 292.3.
