Answer:

The second and third answers are correct.

Step-by-step explanation:

This is a upwards opening parabola.  It has no maximum.  It has a minimum at ( 1,-4).  

The first answers is incorrect.

A function is increasing when it goes up.  It is increasing from 1 to the right  or when x>1 . It is also increasing from - infinity to 1   so x <1

The second answer is correct.

The y intercept is where it crosses the y axis.  This is at the point x = -2

The third answer is correct.

All points on a graph are solutions to the function.  If the function is set equal to zero, then this has two real zeros.

The fourth answer is false.

A constant rate of change means that it is linear.  This is a parabola.  A parabola increases as x^2 not x, so it is not a constant rate of change

The fifth answer is not correct.

The range is the values that y can take.This says y must be less than or equal to -4.  That is not true.  y≥ -4.  

The sixth answer is not correct.

What are the real and complex solutions of the polynomial equation? x^3-8=0. with imaginary numbers
seraphim [82]

Answer:

Solutions are 2,  -1 +  0.5 sqrt10 i  and -1 - 0.5 sqrt10 i

or 2,  -1 +  1.58 i  and -1 - 1.58i

(where the last 2 are equal to nearest hundredth).


Step-by-step explanation:

The real solution is x = 2:-

x^3 - 8 = 0

x^3 = 8

x = cube root of 8 = 2

Note that a cubic equation must have  a total of 3 roots ( real and complex in this case).  We can find the 2 complex roots by using the following identity:-

a^3 - b^3 = (a - b)(a^2 + ab + b^2).

Here  a = x and b = 2 so we have

(x - 2)(x^2 + 2x + 4) = 0

To find the complex roots we solve x^2 + 2x + 4 = 0:-

Using the quadratic formula x = [-2 +/- sqrt(2^2 - 4*1*4)] / 2

= -1 +/- (sqrt( -10)) / 2

= -1 +  0.5 sqrt10 i  and -1 - 0.5 sqrt10 i

The triangles are similar. If KL = 5, JL = 6, and PM = 9, find PN. Round to the nearest tenth.
Pachacha [2.7K]
If the triangles are similar, then the corresponding ratio of their sides have equal ratios. Through ratio and proportion, we would determine the answer.

5/6 = x/9, where x is the length for side PN

Transposing the equation so that x is on the left side:

x = (5/6)*9
x = 7.5
