Answer:

  ∠Y = 45°

Step-by-step explanation:

The sum of complementary angles is 90°.

  ∠Y + ∠S = 90°

  ∠Y + (3(∠y) -90°) = 90°

  4∠Y = 180° . . . . . . . . . . . . add 90°, collect terms

  ∠Y = 45° . . . . . . . . . divide by 4

Answer:

(a) unique triangle(b) more than one triangle(c) no triangle possible

Step-by-step explanation:

1. Three sides lengths uniquely specify a triangle.

__

2. Three angle measures specify the shape of a triangle, but not its size. More than one triangle is possible with any given set of angle measures.

__

3. If the lengths do not satisfy 3 + 7 > 10, which they do not, then no triangle can be formed.

Given:

The quadratic equation is

[tex]y=6x^2-9x+22[/tex]

To find:

The correct application of the quadratic formula.

Solution:

If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then the quadratic formula is

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

We have,

[tex]y=6x^2-9x+22[/tex]

Putting [tex]y=0[/tex], we get

[tex]6x^2-9x+22=0[/tex]

Here, [tex]a=6,b=-9,c=22[/tex]. Using the quadratic formula, we get

[tex]x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(6)(22)}}{2(6)}[/tex]

The correct application of the quadratic formula is [tex]x=\dfrac{-(-9)\pm \sqrt{(-9)^2-4(6)(22)}}{2(6)}[/tex].

Answers

Answer:

-2<x[tex]\leq[/tex]11

Step-by-step explanation:

The line spans from -2 to 11 so we know that those are the values that will be in our expression. -2 has an open circle, therefore, we do not include that value. So any value greater than -2 but not equal to -2 is included. -11 has a closed circle that ends the line segment. This means that any value less than 11 or greater than 11 is included. Therefore the expression would be x is greater than -2 and less than or equal to 11.

  Points on the number will be defined by the inequality → -2 < x ≤ 11.

Symbols to describe an inequality on a number line:   A hollow circle describes the value where the hollow circle is  

           located will not be included and the inequality will be denoted by

           (< or >).

   Solid circle describes the value to be included and denoted by

            (≤ or ≥).

   Dark line between two numbers denotes the values of 'x'

            between the numbers,

From the number line given in the picture,

Dark line starts with a hollow circle from x = -2

Dark line ends with a dark circle at x = 11.

Inequality for this situation will be → -2 < x ≤ 11

            Therefore, points on the number will be defined by the inequality → -2 < x ≤ 11.

True False The New Baby For 12 wonderful years, Cara had enjoyed her position as the youngest of five children, the baby of the family. But for the past nine months Cara had felt her special place slipping away as the family prepared for her oldest sister to give birth. Now, Caras parents would become grandparents and there would be a new baby to fawn over, which had not happened since Cara was born. Cara worried that her mother would forget about her and spend all her time with the new baby. She was less than thrilled as she rode the elevator to the hospitals ninth floor. The room was so full of family members and flower bouquets that Cara had trouble seeing the hospital bed. Angela, Caras sister, sat propped up by pillows. She cradled a squirming pink bundle in the crook of one arm. She grinned when she saw Cara and her parents and turned the pink bundle towards them. Only the babys face was visible. Her hands punched out under the swaddling. Caras mother was the first to hold the baby. She smiled and cooed at the baby. Then the baby was being passed to Cara, and she was face-to-face with her new niece. The baby squirmed a bit and then opened her eyes and looked right at Cara. The baby cooed at Cara, and Cara smiled at her niece, thinking that becoming an aunt might be wonderful after all.3.
