Answer:

Since [tex]AB \neq BC \neq AC[/tex] and [tex]\cos B = 0[/tex], we conclude that given triangle is a right-angled and scalene.

Step-by-step explanation:

First, we determine the lengths of sides [tex]AB[/tex], [tex]BC[/tex] and [tex]AC[/tex] by the Equation of the Line Segment, which is based on the Pythagorean Theorem:

Line segment AB

[tex]AB = \sqrt{(4-1)^{2}+ (4-1)^{2}}[/tex]

[tex]AB = 3\sqrt{2}[/tex]

Line segment BC

[tex]BC = \sqrt{(6-4)^{2}+(2-4)^{2}}[/tex]

[tex]BC = 2\sqrt{2}[/tex]

Line segment AC

[tex]AC = \sqrt{(6-1)^{2}+(2-1)^{2}}[/tex]

[tex]AC = \sqrt{26}[/tex]

And the angles are found by means of the Law of Cosine:, where acute angles exist when [tex]0 < \cos \theta < 1[/tex], whereas obtuse angles exist for [tex]-1 < \cos \theta < 0[/tex].

Angle A

[tex]BC^{2} = AB^{2} + AC^{2} - 2\cdot AB\cdot AC \cdot \cos A[/tex] (1)

[tex]\cos A = \frac{BC^{2}-AB^{2}-AC^{2}}{-2\cdot AB\cdot AC}[/tex]

[tex]\cos A = \frac{8-18-26}{-2\dot (3\sqrt{2})\cdot (\sqrt{26})}[/tex]

[tex]\cos A = 0.832[/tex]

Angle B

[tex]AC^{2} = AB^{2} + BC^{2} - 2\cdot AB\cdot BC\cdot \cos B[/tex] (2)

[tex]\cos B = \frac{AC^{2}-AB^{2}-BC^{2}}{-2\cdot AB\cdot BC}[/tex]

[tex]\cos B = \frac{26-18-8}{-2\cdot (3\sqrt{2})\cdot (2\sqrt{2})}[/tex]

[tex]\cos B = 0[/tex]

Angle C

[tex]AB^{2} = AC^{2}+BC^{2}-2\cdot AC\cdot BC\cdot \cos C[/tex] (3)

[tex]\cos C = \frac{AB^{2}-AC^{2}-BC^{2}}{-2\cdot AC\cdot BC}[/tex]

[tex]\cos C = \frac{18 -26-8}{-2\cdot (\sqrt{26})\cdot (2\sqrt{2})}[/tex]

[tex]\cos C = 0.555[/tex]

Since [tex]AB \neq BC \neq AC[/tex] and [tex]\cos B = 0[/tex], we conclude that given triangle is a right-angled and scalene.

Questions that followed :

What does the slope of the graph of this equation represent?

What does y-intercept of the graph of this equation represent?

Answer:

Kindly check explanation

Step-by-step explanation:

Given the model:

y = 16,500 - 1,500x

The slope = - 1500 ; this is a negative slope and means that the dependent variable will decrease with increase in the independent variable.

This means that, the market value of a car will decrease by 1500 per unit increase in year (a yearly fall of 1500 from the market value of cars per year after purchase).

The y - intercept is the value of y (market value) when x (number of years ) = 0 ; This means that the intercept value of 16500, is the initial prove of the car ; current value when the car hasn't been used.

Answer:

C. f(x) = 3·x + 2, g(x) = 7·x + 6

Step-by-step explanation:

The given equations relates to the property of equality of values;

The given formula for the association between f(x) and g(x) is f(x) = g(x)

The given equation of two expressions is 3·x + 2 = 7·x + 6

By transitive property of equality, the two above equations are correct when f(x) = 3·x + 2 and g(x) = 7·x + 6

Therefore, the function that may be used to represent the equation is option C; f(x) = 3·x + 2, g(x) = 7·x + 6.

Answer:

-9; 1

Step-by-step explanation:

x+4=5

x=5-4

x=1

x+4=-5

x=-5-4

x=-9

The solution of the quadratic equation (x + 4)^2 = 25 is x = -9 and x = 1

The correct answer is option (C)

"It is a polynomial with degree 2. The general form of quadratic equation is ax²+ b x + c =0, where a, b, c are real numbers with a ≠ 0."

For given example,

We need to find the solution of the quadratic equation (x + 4)^2 = 25.

⇒ (x + 4)^2 = 25

⇒ x² + 2(4)(x) + (4)² = 25

⇒ x² + 8x + 16 = 25

⇒ x² + 8x - 9 = 0

⇒ x² + 9x - x - 9 = 0

⇒ x(x + 9) - 1(x + 9) = 0

⇒ (x + 9)(x - 1) = 0

⇒ x + 9 = 0   and x - 1 = 0

⇒ x = -9 and x = 1

The correct answer is option (C)

Answer:

15/10

Step-by-step explanation:

Since it is adding you need to get a common denominator(bottom number).

I know that 2 × 5 = 10 so now we multiply 3/5 × 2

we get 6/10

now the problem is 9/10 + 6/10

9 + 6 = 15 and the denominator is 10

Step-by-step explanation:

The slant height of the pyramid is marked as 5. If we drew and auxiliary 2D right triangle in the pyramid, this slant height would be the hypotenuse and one of the legs would be the height of the pyramid. The base leg would be equal to half of a side of the pyramid (3). Therefore, we can use the Pythagorean theorem to find the height ([tex]h[/tex]):

[tex]3^2+h^2=5^2,\\h^2=16,\\h=\boxed{4}[/tex]

Answer: Cara takes longer to get to the library. She used 3 minutes more

Step-by-step explanation:

Cara leaves her house at 10:03 and arrives at the library at 10:17. The number of minutes used by Cara will be:

= 10.17 - 10.03

= 14 minutes

Irena leaves her house at 11:55 and arrives at the library at 12:06. The number of minutes used by Irena will be:

= 12.06 - 11.55

= 11 minutes

Cara takes longer to get to the library. She used (14 - 11) = 3 minutes more

Answer: a) 8/12

Step-by-step explanation:

Both numbers have to be the same for it to be equal: More info below.

The answer is a) because 8 divided by 2 is 4, and 12 divided by 3 is also 4.

It is not b) because 6 divided by 2 is 3, but 12 divided by 3 is 4.

Not c) because 9 divided by 2 is 4.5, and 12 divided by 3 is 4.

Not d) because 10 divided by 2 is 5, and 12 divided by 3 is 4.

Therefore, the answer is a) 8/12.
