Answer:

  2

Step-by-step explanation:

The values of a, b, c are ...

  a = 1, b = -3, c = 2

Then the discriminant is ...

  d = b^2 -4ac

  d = (-3)^2 -4(1)(2) = 9 -8 = 1

The discriminant is positive, so there are two x-intercepts.

Additional comment

The indications given by the discriminant are ...

  d > 0, 2 real roots (2 x-intercepts)

  d = 0, 1 real root (1 x-intercept)

  d < 0, 2 complex roots (0 x-intercepts)

Answer:

  f(x) = 4·3^x

Step-by-step explanation:

We assume the function will be of the form ...

  f(x) = a·b^x

Substituting the given values, we can find 'a' and 'b'.

  4/9 = a·b^(-2)

  108 = a·b^3

Dividing the second equation by the first gives ...

  108/(4/9) = b^(3 -(-2))

  243 = b^5

  b = 3 . . . . . . 5th root

Using the second equation, we can find 'a':

  108 = a·3^3 = 27a

  a = 108/27 = 4

The formula for the exponential function is ...

  f(x) = 4·3^x

Answer:

3 or 3/1

Step-by-step explanation.

since 9 is in parenthuses, do 2x9, then you have the fraction 6/18, and 6 does into 18 3 times evenly, so the answer is 3.

The simplification form of the fraction 6/2(9) is 1/3 after using the concept of fraction and basic arithmetic operation.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

The fraction is:

= 6/2(9)

From the definition of the fraction, the top of the fraction number is called the numerator and the second is the bottom of the fraction number which is called the denominator.

In the given fraction the number 6 is in the numerator and 2(9) is in the denominator.

= 6/18  (after the multiplication of 2 and 9)

= 1/3  (divide by 6 on the numerator and denominator)

Thus, the simplification form of the fraction 6/2(9) is 1/3 after using the concept of fraction and basic arithmetic operation.

Answer:

  B.  False

Step-by-step explanation:

The three pairs of corresponding angles have the same measures, so the triangles are similar by AA similarity. However, at least one pair of corresponding sides must be shown congruent before the triangles can be declared congruent.

There is nothing in the diagram to require the triangles be congruent.

With three corresponding equal angles triangles are not congruent. Therefore, the given statement is false.

Triangle congruence theorem or triangle congruence criteria help in proving if a triangle is congruent or not. The word congruent means exactly equal in shape and size no matter if we turn it, flip it or rotate it.

The three pairs of corresponding angles have the same measures, so the triangles are similar by AA similarity. However, at least one pair of corresponding sides must be shown congruent before the triangles can be declared congruent.

With three corresponding equal angles triangles are not congruent. Therefore, the given statement is false.

The index form of the fraction  [tex]\frac{1}{(7^{(\frac{1}{5})}) }[/tex] is written as [tex]7^{(\frac{-1}{5})}[/tex] where the exponent notation is [tex]7^{(\frac{-1}{5})}[/tex].

Given data:

In index form, the expression  [tex]\frac{1}{(7^{(\frac{1}{5})}) }[/tex] is written as [tex]7^{(\frac{-1}{5})}[/tex] , where the base is 7 and the exponent is -1/5. This means that we are taking the reciprocal of the fifth root of 7. The exponent of -1/5 indicates that we are essentially finding the inverse of the fifth root of 7.

When dealing with fractional exponents, the denominator of the fraction becomes the root, and the numerator becomes the power to which the base is raised. In this case, the base is 7, the denominator is 5, and the numerator is -1. So, [tex]7^{(\frac{-1}{5})}[/tex]  represents the reciprocal of the fifth root of 7, which can also be expressed as the fifth root of 7 raised to the power of -1.

Hence, the exponent notation is [tex]7^{(\frac{-1}{5})}[/tex].

Emiliano divided by two instead of multiplying. To solve the equation, he had to multiply both sides by two so that he could see what x equals when it's alone (if half of x is 80, x, or two halves, is 160).

The solution of the given equation is 160. Emiliano wrong because instead of multiplying he must have divided 80 by 2.

The given equation is 1/2 x=80.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The solution of the given equation is

1/2 x=80

⇒ x =80×2

⇒ x =160

The solution of the given equation is 160. Emiliano wrong because instead of multiplying he must have divided 80 by 2.

Answer:

6 Km / hour

Step-by-step explanation:

Convert distance to Km ( 1 Km = 1000 m )

150 m = 150 ÷ 1000 = 0.15 Km

Convert 1.5 mins to hours ( 1 hour = 60 minutes )

1.5 = 1.5 ÷ 60 = 0.025 hours

average speed = [tex]\frac{distance}{time}[/tex] = [tex]\frac{0.15}{0.025}[/tex] = 6 Km / hour

The average speed in km per hour is 6 kilometers per hour

The given parameters are:

Convert meters to kilometers

Distance = 150/1000 km

Distance = 0.15 km

Convert minutes to hours

Time = 1.5/60 hour

Time = 0.025 hour

The average speed is then calculated as:

Speed = Distance/Time

This gives

Speed = 0.15 km/0.025 hour

Evaluate

Speed = 6 kilometers per hour

Hence, the average speed in km per hour is 6 kilometers per hour
