Answers

Answer 1

Answer:

1. x =-4 (-4,27)

x =0 (0,3)

x = 2 (2 , -9)

2. x = -1 (-1 , 3)

x = -2 (-2 , 2)

x = -3 ( -3, 1)

3. x = -3 (-3 , 13)

x = 1 (1 , 1)

x = -2 ( -2, 10)

4. x =2 (2 , 24)

x = 3 (3 , 30)

x = -2 (-2 , 0)

5.x = -3 (-3 , -2)

x = 2 (2 ,-12 )

x =4 (4 , -16)

6. x = -1 (-1 , -2)

x = 0 (0 , 2)

x = 2 (2 , 10)

Prove that the roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k

Answers

The roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k

The equation is given as:

x^2 + (1 - k).x+k-3 = 0

For an equation to have real root, then the following must be true:

[tex]b^2 \ge 4ac[/tex]

In x^2 + (1 - k).x+k-3 = 0, we have:

a = 1

b = 1 - k

c = k - 3

So, we have:

[tex](1 - k)^2 \ge 4 * 1 * (k - 3)[/tex]

Evaluate

[tex]1 - 2k + k^2 \ge 4k - 12[/tex]

Collect like terms

[tex]k^2 - 2k - 4k + 1 + 12 \ge 0[/tex]

[tex]k^2 - 6k + 13 \ge 0[/tex]

Using a graphing calculator, the value of k is all real numbers

Hence, the roots of x^2 + (1 - k).x+k-3 = 0 are real for all real values of k

A right prism has height 7½ and triangular bases with sides of length 5, 12, and 13 What is the: Total Surface Area of the Prism

Answers

Given:

A right prism has height 7½ and triangular bases with sides of length 5, 12, and 13.

To find:

The total surface area of the prism.

Solution:

We have,

Height of prism = 7½ = 7.5

Sides of triangular base are 5, 12, 13. These sides of Pythagorean triplets because

[tex]5^2+12^2=13^2[/tex]

[tex]25+144=169[/tex]

[tex]169=169[/tex]

So, the base of the prism is a right triangle.

Area of a triangle is

[tex]Area=\dfrac{1}{2}\times base \times height[/tex]

[tex]A_1=\dfrac{1}{2}\times 5\times 12[/tex]

[tex]A_1=30[/tex]

The area of the base is equal to the area of the top, i.e., [tex]A_2=30[/tex] sq units.

Perimeter of the base is

[tex]P=5+12+13[/tex]

[tex]P=30[/tex]

The curved surface area of the prism is

[tex]CSA=\text{Perimeter of the base}\times \text{Height of the prism}[/tex]

[tex]CSA=30\times 7.5[/tex]

[tex]CSA=225[/tex]

Now, the total area of the prism is

[tex]A=A_1+A_2+CSA[/tex]

[tex]A=30+30+225[/tex]

[tex]A=285[/tex]

Therefore, the total surface area of the triangular prism is 285 square units.

What equivalent fractions for 2 3/5 and 1 1/3 using a common denominator

Answers

Answer:

The common denominator is 15.

2 3/5 = 13/5 = 39/15

1 1/3 = 4/3 = 20/15

Answer:

39/15 and 20/15

Step-by-step explanation:

Given function:

2 3/5 and 1 1/3to find the equivalent fraction for both fraction using common denominator..

Rewrite 2 3/5 and 1 1/3 by a number that is equivalent to 5 and 3:

[tex]5,10,15[/tex] [tex]3,6,9,12,15[/tex]

Multiply each numerator by how much times it turned into 15:

[tex]3[/tex]·[tex]3=9[/tex] [tex]1[/tex]·[tex]5=5[/tex]

Simplfly the fraction terms:

[tex]2\frac{9}{15}=\frac{39}{15}[/tex] [tex]1\frac{5}{15}=\frac{20}{15}[/tex]

Therefore, 39/15 and 20/15 is equivalent to 2 3/5 and 1 1/3.

Triangle ABC is similar to triangle A'B'C'. Calculate the length of side A'B'. Then check your
answer using a different method.

Answers

Answer:

A'B' = 7.5

Step-by-step explanation:

uhhh

AC = A'C'

4 = 6

×1.5

AB^2 = 4^2 + 3^2

AB^2 = 16 + 9

AB^2 = 25

AB = √25

AB = 5

A'B' = 5 × 1.5 = 7.5

The value of A'B' for the given congruent triangle will be 7.5.

What is congruence?

If two figures are exactly the same in sense of their side of all things then they will be congruent.

If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent or to be in the relation of congruence.

As per the given congruent triangle,

In triangle ABC,

AB = √(3² + 4²) = 5

The ratio of the corresponding sides of the two triangles is the same.

A'B'/A'C' = AB/AC

A'B'/6 = 5/4

A'B' = 30/4 = 7.5

Hence "The value of A'B' for the given congruent triangle will be 7.5".

if XYZ ~ RST, find RS

Answers

Answer:

RS = 38

Step-by-step explanation:

20x - 12 = 18x + 12

2x = 24

x = 12

3(12) + 2 = 38

The value of the side of triangle RS is equal to 38.

What is the similarity?

If two objects are having the same shape then they will be termed as similar. So in mathematics, if two figures have the same shapes, lines or angles then they are called similar.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the sides of the triangle XYZ are, XY = 5x - 3, XZ = 60 and the sides of the triangle TR = 40, RS = 3x + 2.

The value of RS will be calculated as,

( 5x - 3 ) / ( 3x + 2 ) = ( 60 / 40 )

( 5x - 3 ) / ( 3x + 2 ) = ( 6 / 4 )

20x - 12 = 18x + 12

2x = 24

x = 12

RS = 3x + 2

RS = ( 3 x 12 ) + 2

RS = 36 + 2

RS = 38

Therefore, the value of the side of triangle RS is equal to 38.
