Consider the quadratic function, f(x)=-2x^2+12x+32=0. Select all statements that are true for the function. The value of the discriminant is -112. The value of the discriminant is 20. The value of the discriminant is 400. The function has 1 real solution. The function has 2 real solutions. The function has 2 complex solutions.

Answers

Answer:

Step-by-step explanation:

-2x² + 12x  + 32 = 0

discriminant = 12² - 4(-2)(32) = 400

positive discriminant means there are two distinct real roots

x = [-12 ± √(12² – 4(-2)·32)] / [2·(-2)]

 = [-12 ± √400] / (-4)

 = [-12 ± 20] /(-4)

 = 8, -2

Kayla is thinking of a 3-digit number.

* It is divisible by 18.

* It is a palindrome (It reads the same left-to-right as it does right-to-left, like 252 and 848).

* It is one less than a multiple of 5.

What is Kayla’s number?

Answers

Answer:

kaylas thinking of the number 414

Step-by-step explanation:

414 is divisable by 18 (414 divided by 23)

414 is palindrome

414 is one less than a multiple of 5 (415)

Answer:

414

Step-by-step explanation:

The last digit must be 4 or 9 since it is one less than a multiple of five. Then, it says the number must be divisible by 18, and 18 = 2x9. Only 4 is divisible by 2, so four must be the last digit. Since it's a palindrome, the first digit must also be four. Since it also has to be divisible by nine, 4 + 4 = 8, and 8 + 1 = 9.

The points are (1, 1), (2, 2), (3, 4), (4, 8). On a coordinate plane, 3 points are plotted. The points are (1, 2), (4, 4), (9, 6). On a coordinate plane, 3 points are plotted. The points are (1, 1), (2, 4), (3, 9).

Answers

Answer:

Graph B is the correct answer. Just in case it is not choice B for you, it's the graph with points (1,1), (2,2), (3,4), and (4,8) in that order. Sadly, the other guy is incorrect and you should not listen to him.

Step-by-step explanation:

The graph that represents a geometric sequence is (b) (1, 1), (2, 2), (3, 4), (4, 8)

What is a geometric sequence?

A geometric sequence is a sequence that has a common ratio

The common ratio of a geometric sequence is calculated as:

[tex]r = \frac{y_2}{y_1}[/tex]

Using the above rule, we have:

[tex]r = \frac{2}{1} = \frac 42 = \frac 84[/tex]

[tex]r =2 =2 =2[/tex]

The above represents option B, and it has a common ratio of 2

Hence, the graph that represents a geometric sequence is (b) (1, 1), (2, 2), (3, 4), (4, 8)

Find the value of x that makes lines u and v parallel, answer needed

Answers

Given:

u and v are parallel lines.

To find:

The value of x.

Solution:

If a transversal line intersect the two parallel lines, then

(1) Corresponding angles are congruent.

(2) Same sides interior angles are supplementary angles and their sum is 180 degrees.

15.

[tex]23x-2=90[/tex]           (Corresponding angles)

[tex]23x=90+2[/tex]

[tex]x=\dfrac{92}{23}[/tex]

[tex]x=4[/tex]

Therefore, the value of x is 4.

16.

[tex](x+106)+(x+86)=180[/tex]         (Same sided interior angles)

[tex]2x+192=180[/tex]

[tex]2x=180-192[/tex]

[tex]2x=-12[/tex]

Divide both sides by 2.

[tex]x=\dfrac{-12}{2}[/tex]

[tex]x=-6[/tex]

Therefore, the value of x is -6.
