The two triangles ΔABC and ΔDEC are similar as the triangles follow the angle-angle axiom of similarity .

In the given triangles ΔABC and ΔDEC

In ΔABC

∠ABC = 21°

∠BAC = 36°

∠ACB = 180° - (36+21)°

or, ∠ACB = 180° - (57)° = 123°

In ΔDEC

∠CDE = 36°

∠DCE = 123°

∠CED = 21°

Therefore we can see that the two triangles are similar as all the angles are equal.

Hence the ΔABC and ΔDEC has 3 congruent angles by the angle sum property and the triangles are similar by angle-angle-angle axiom of similarity.

Two triangles are considered to be similar if their corresponding sides and angles match. Alternatively, comparable triangles may have the same shape but vary in size. The triangles are also congruent if the lengths of their respective sides are the same.

1/4 = 2x

(1/4)/2 = x/2

1/8 = x

Answer: x = -2

Step-by-step explanation:

X is -2 because whenever you get a negative exponent you gotta make it into a fraction which is [tex]\frac{1}{4}[/tex] because I ignored the negative sign for a second and did it normally so 2 to the power of 2 is 4 put it as a fraction 1 over 4.

To generate the overall equation A → 2C, should be B → 2C added to  

A → B gives the equation A + B → B + 2C.  

In mathematics, an equation is a method that expresses the equality of two expressions, by using connecting them with the equals signal =. The phrase equation and its cognates in other languages may also have subtly exclusive meanings; for example, in French, an equation is described as containing one or more variables, at the same time as in English, any nicely shaped formula together with expressions associated with an equal’s signal is an equation.

Solving an equation containing variables includes determining which values of the variables make the equality actual. The variables for which the equation must be solved are also known as unknowns, and the values of the unknowns that satisfy the equality are referred to as solutions of the equation. Equations come in two varieties: identities and conditional equations. An identification is actual for all values of the variables. A conditional equation is handiest genuine for unique values of the variables.

The price of one sweater is $15 and the price of one shirt is $10.

The first step is to form a set of linear equations using the information provided in the question:

s + 4p = $55 equation 1

4s + 5p = $110 equation 2

Where:

In order to determine the value of p, take the following steps:

Multiply equation 1 by 4

The fourth option D is a function of the form of f(x) = ax(x-2)(x+2) where a is a constant.

We know that any function of the form y = f(x) will pass through the x axis at points such that there is only 1 value of x for a value of y.

Of all the options given the option D is in the form of polynomial expression which crosses the x-axis at points (-2,0 ) ,  (0,0) and (0,2).

The graph of the function at D will be of the form:

f(x) = ax(x-2)(x+2) a is a constant.

At y = 0 , x =-2 ,0 and 2.

Therefore for one value of y there are 3 values of x. but every value of x is mapped into one single value of y only.

For option A at x = 2 , y ahs two values -2 and 2 so it is not a function of x.

For option B  the graph is not differentiable at certain points, hence it is not a function.

For option C again y has 2 values for a single x.

The values of x are used to denote the roots and zeros of the expression, which are also on the left side of the equation, and to satisfy the equation. A quadratic problem should only have two possible solutions. One contends that if there is just one solution, the problem has numerous causes.

The smallest number of instances at which the acceleration of the plane could equal zero on the open interval 0 < c < 6 is t= 25 to t= 30.

By the mean value theorem, somewhere between t = 0 and t = 15 , v'(t) = 0, because v(15)-v(0)/15-0 = 0. Also somewhere between t=25 and t=30, v'(t) = 0, because v(30) - v(25) / 30 - 25 = 0. This means a(t) = 0 for at least two values of t.

f(t) = 6+cos(t/10)+3sin(7t/40)

a(t) = f'(t) = 1/10 sin (t/10) + 21/40 cos (7t/40)

Answer:

  -6, 1

Step-by-step explanation:

You want the real roots of the quadratic x^2 + 5x = 6.

The roots are easily identified from the factored form of the equation. The factors will involve the constants that have a sum of +5 and a product of -6.

  -6 = 6·(-1) = 3·(-2)

Sums of the factor pairs are 5 and 1. We will use the constants that have a sum of 5.

  x^2 +5x = 6 . . . . . . given

  x^2 +5x -6 = 0 . . . . . standard form

  (x +6)(x -1) = 0 . . . . . . . factored form

The zero product rule tells us that a product will be zero if and only if at least one of the factors is zero. To find the values of x, we set the factors equal to zero and solve for x.

  (x +6) = 0   ⇒   x = -6

  (x -1) = 0   ⇒   x = 1

  x = -6, or x = 1 . . . . . . . . roots of the quadratic

The zeros, the polynomial x³-5x²+8x-6 are 3, (1-i) and (1+i) and factors are

(x-3)(x²-2x+2)

Zeros of a polynomial can be defined as the points where the polynomial becomes zero as a whole.

Given a polynomial (x³-5x²+8x-6)

x³-5x²+8x-6 = (x-3)(x²-2x+2)

(x²-2x+2) can't be factorized and will have imaginary roots,

The correct option (4)

A function is defined as a relationship between a collection of inputs with one output each. In simple terms, a function is a relationship between inputs, with each input corresponding to exactly one output. Every function has a domain and a codomain or range. A function is commonly denoted by f(x), where x is the input.

From the given information, we have that

f(x) = 3x - 4 and

g(x) = f(2x)

Then,

g(x) = f(2x) becomes

g(x) = f(2x) = 3(2x) -4

g(x) = 6x - 4

Now, we'll plug x numbers ranging from 1 to 3 into the equation.

When x = 1

g(x) = 6x - 4 becomes

g(x) = 6(1) - 4

g(x) = 6 - 4

g(x) = 2

When x = 2

g(x) = 6x - 4 becomes

g(x) = 6(2) - 4

g(x) = 12 - 4

g(x) = 8

When x = 3

g(x) = 6x - 4 becomes

g(x) = 6(3) - 4

g(x) = 18 - 4

g(x) = 14

Hence, the table that represents g(x) is

x         g(x)

1          2

Answer:

The voltage in an electrical circuit is multiplied by itself each time it is reduced. The voltage is 27 /125 of a volt and has been reduced 3 times.

Write the voltage in exponential form.

What was the original voltage in the circuit?

Step-by-step explanation:

voltage = v

v³ - exponential form

v³ = 27/125

make v³ a fraction so v³/1 then cross multiply

so... 125v³ = 27 then v³ = 27/125 or v³ = 0.216 if you like decimals better then to get v by it self you cube root mean v = ∛27/125

original voltage in circuit - v = ∛27/125

The information in the word problem indicates that the initial total number of marbles that were given to the three of them at the beginning of the game was 40 marbles

A word problem consists of describing a situation as well as providing the necessary information to a question verbally that is to be solved by by calculations mathematically.

The initial number of marbles Brea had = 10

The number of marbles Brea had at the end = 0

Let A represent the number of marbles given to Abby, let B represent the number of marbles given to Brea and let C represent the number of marbles given to Cleo, we get;

The number of marbles Abby gave Brea and Cleo = B + C

The number of marbles Brea gave Abby and Cleo = (A - (B + C)) + 2·C

The number of marbles Brea gave Abby and Cleo = All her marbles = 2·B

Therefore;

20 = (A - (B + C)) + 2·C = (A - (10 + C)) + 2·C

20 = A - 10 + C

A + C = 20 + 10 = 30

A + B + C = A + 10 + C = A + C + 10 = 30 + 10 = 40
