Sine, Cosine, Tangent question below

All the given triangles are congruent by SSS, SAS, and AAA rules.

If two figures are exactly the same in sense of their length side 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 triangles,

In the first triangle, two sides are the same and the third side is the common side thus it will be congruent with the SSS rule.

The remaining triangles are also congruent similarly to SAS and AAA rules like this.

Hence "By the SSS, SAS, and AAA criteria, every triangle in the example is congruent.".

Answer:

The slope of a line perpendicular to the line y=1/3x-2 is the negative reciprocal of the slope of that line. The slope of the line y=1/3x-2 is 1/3, so the slope of a line perpendicular to it is -3.

A slope of -5/8 and 8/5 are perpendicular.

Lines that are perpendicular have slopes that are opposite reciprocals of one another.

Answer:

1.727 x 10^4

Step-by-step explanation:

2.26 x 10^4 = 22 600

5.33 x 10³ = 5330

22 600 - 5330 = 17 270

17 270 = 1.727 x 10^4

The two numbers are 12 and 14 (using quadratic equation)

Let two numbers be a and b

given,

(a + b)/2 = 13 ⇒ a + b = 26 ⇒a = 26 - b→ eq 1

also,

ab = 133

using eq 1 in ab = 133 we get,

[tex]b^{2}[/tex] - 26b + 133 = 0

using quadratic formula,

[tex]\frac{-b+- \sqrt{b^{2}-4ac } }{2a}[/tex]

we get b = 38,14

if b = 38, a = -12, which doesn't satisfy the question

so, b = 14, a = 12

quadratic equation:

The definition of a quadratic as a second-degree polynomial equation demands that at least one squared term must be included. It also goes by the name quadratic equations. The quadratic equation has the following generic form:

ax² + bx + c = 0

where a, b, and c are numerical coefficients and x is an unknown variable. An example of a quadratic equation is x2 + 2x + 1. Here, an is greater than zero because if it equals zero, the equation will cease to be quadratic and change to a linear equation, such as:

bx+c=0

As a result, we cannot refer to this equation as a quadratic equation.

Another name for the terms a, b, and c is quadratic coefficients.

(A) The rate of making coffee by coffee maker  is 6 mL/second.

(B) The rate of making juice by juice maker is 8 mL/second.

(C) Juice is being made at a faster rate.

Ratio basically compares quantities, that means it show value of one quantity with respect to other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

The rate of coffee made by coffee maker is represented by,

y = 6x       (1)

Here, y represents the amount of coffee in mL and x represents the time passed in seconds.

Also, The rate of juice made by juice make can be represented by the given table as,

k = 8h     (2)

Here, k represents the amount of juice in mL and h represents the time passed in seconds.

(A)

To find the rate of making coffee, solve the equation (1),

y = 6x

⇒ y/x = 6 mL/second

The rate of making coffee by coffee maker  is 6 mL/second.

(B)

To find the rate of making juice, solve the equation (2),

k = 8h

⇒ k/h = 8 mL/second

The rate of making juice by juice maker is 8 mL/second.

(C)

Since, the juice is made at the rate of 8 mL/second and the coffee is made at the rate of 6 mL/second.

Therefore, juice is being made at a faster rate.

Answer:

first and fourth statements are true

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180° , so

2x + 1 + x + x + 15 = 180 , that is

4x + 16 = 180 ( subtract 16 from both sides ) ← True

4x = 164 ( divide both sides by 4 )

x = 41 ≠ 49

then

∠ A = 2x + 1 = 2(41) + 1 = 82 + 1 = 83° ≠ 99°

∠ C = x + 15 = 41 + 15 = 56° ← True

The response choice that include the true statements based on the number line is the second option;

Point B represents [tex]-2\frac{1}{2}[/tex], Point C represents 1, and 1 > [tex]-2\frac{1}{2}[/tex]

A number line is a line that contains (equally spaced) markings, which is then used to illustrate mathematical operations.

The number line in the question is presented as follows;

<________|_____|_____|__|__|____|____|____|___|_|____|_____|____>

                -5          A               B                     0       C      D                     5  [tex]{}[/tex]

Therefore, based on the number line, we get;

The location of the point A is 4 units to the left of the point 0, taking the points to the right of zero as positive, we get;

Each unit to the left of point O, is -1 larger than the previous value, moving from right to left.

The coordinates of the point A is therefore, -1 × 4 = -4

The location of the point C is one unit to the right of 0, therefore, the coordinates of the point C is 1

The location of the point C = 1 is further right to 0 than the point B = -2 1/2

Therefore;

The correct option is; Point B represents -2 1/2, Point C represents 1, and 1 > -2 1/2

The next number in the given sequence is 256

What is Fibonacci sequence?

Leonardo Pisano Bogollo, an Italian, was the first to discover the Fibonacci sequence (Fibonacci). The numbers in the Fibonacci sequence are all whole numbers: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34,... Each phrase in this infinite sequence—which has 0 and 1 as its initial values—is the sum of the two terms before it. This pattern has been referred to as "nature's secret code."

Sunflowers, daisies, broccoli, cauliflower, seashells, and other spiral-shaped plants all display the Fibonacci sequence.

Observe that, the terms in the sequence are based on the 2 to the power of the Fibonacci series (0,1,1,2,3,5,8 …)

2^0=1

2^1=2

2^1=2

2^2=4

2^3=8

2^5=32

2^8=256
