Answer:

(f/g)(x) = \(\frac{2x^2-5}{3x+2}\) x can not equal -2/3

Step-by-step explanation:

(f / g) is telling you to make f the numerator and g as the denominator.

It also wants you to state the domain restriction. When you divide by something, remember you can not divide by 0 under any circumstances. This means, you need to find what combination of x values will result in the denominator equaling 0.

(f / g) (x)

\(\frac{2x^2-5}{3x+2}\)

Domain restrictions

As you can see here, our denominator is: 3x+2. What set of x values will result in 3x+2 equating to zero? To find this, set up the equation so that it equals zero.

\(3x+2=0\\3x+2-2=0-2\\3x=-2\\3x/3=-2/3\\x=-\frac{2}{3}\)

If you are not sure, replace x with the value you came up with.

To check, replace x with -2/3

\(3(-\frac{2}{3})+2=0\\-2+2=0\\0=0\)

Answer:

67.5 or 67 1/2

Step-by-step explanation:

15   ÷              2

         ___________            

                   9

The numbers in 15 divided by 2/9 are labeled below:

15 = whole number

2 = numerator

9 = denominator

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

15 x 9 2  =     135

                       ____

                          2

Thus, the answer to 15 divided by 2/9 in fraction form is:

 135

_____

   2

To make the answer to 15 divided by 2/9 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

135 / 2 = 67.5

The answer is rounded to the nearest two decimal points if necessary.

135/2 is an improper fraction and should be written as 67.5 or 67 1/2.

Hope this helps, have a nice day/night! :D

Answer:

67.5

Step-by-step explanation:

15 = 135/9

135/9 x 9/2 = 15 x 4.5 = 67.5

            9/2 = 4.5

The angle measures for this problem are given as follows:

The sum of the measures of the internal angles of a triangle is of 180º.

The triangle in this problem is ABC, hence the measure of a is obtained as follows:

a + 68 + 50 = 180

a = 180 - (68 + 50)

a = 62º.

c and d are corresponding angles to angle a, as they are on the same position relative to parallel lines, hence their measures are given as follows:

Angle b is a corresponding interior angle with angle a, hence they are supplementary and it's measure is given as follows:

a + b = 180

62 + b = 180

b = 118º.

Answer:  k = {8, -8}

Step-by-step explanation:

In order for a quadratic equation to have exactly one solution, the discriminant must equal zero.       →        b² - 4ac = 0

The number of hours Nick took to reach the shopping mall in terms of r  is ; 3.14  hours.

Rate is a measure of a quantity using another quantity as the basis.

Analysis:

speed travelling on foot = r

distance travelled on foot = 5 miles

time taken = 5/r

speed travelling on bicycle 80 percent faster than on foot is 1.8r

distance travelled on bicycle = 8 miles

time taken = 8/1.8r = 40/9r

total time taken to get to the mall = 5/r + 40/9r = 85/9r

speed while walking = 3 miles per hour = r

time taken = 85/9 x 3 = 3.14 hours

In conclusion, number of hours Nick took to reach the shopping mall in terms of r is 85/9r is 3.14  hours.

Answer:

  (c)  {15 -√235, 15 +√235}

Step-by-step explanation:

For solutions p and q, the trinomial is ...

  (x -p)(x -q) = x² -(p+q)x +pq

That is, the constant term (-10) must be the product of the roots, and the x-coefficient (-30) must be the opposite of their sum.

The sums of roots in the answer choices are ...

  a) 30

  b) -30

  c) 30

  d) -30

We know the sum of roots is 30, so we can eliminate choices 'b' and 'd'.

The product of the roots must be -10, eliminating choice 'a'. Thus, the only viable choice is C.

Here

so the required distance is 2200 miles.

The required amount of the space available is 0.045 cubic meter.

We need to determine Space inside the steps.

The Volume is defined as the mass of object per unit density.

The required space = 0.3*0.4*0.5 - 0.15*0.5*0.2

                                 =  0.06 - 0.015

answer: the range is 41.

Determine whether the statement is true or false. If it is false, provide an explanation or give an example.

If f is decreasing on [a,b] then the minimum value of f(x) on [a,b] is f(a)?

Answer:

False

Step-by-step explanation:

Given

[a,b]

Where f(x) is decreasing

Required

Is the minimum f(a)?

This statement is false and it is proved using the following illustration

Take f(x) to be

\(f(x) = -2x\)

The above represents a decreasing function because:

f(x) decreases as x increases

Having said that:

Assume [a,b] is:

\([a,b] = [2,5]\)

Substitute the value of a i.e. 2 for x in f(x)

\(f(2) = -2 * 2\)

\(f(2) = -4\)

Substitute the value of b i.e. 5 for x in f(x)

\(f(5) = -2 * 5\)

\(f(5) = -10\)

Notice that f(b) < f(a) i.e. -10 is less than -4

Hence:

f(x) is minimum at f(b)

Conclusively, the statement is false

Step-by-step explanation:

f(x) = 0

-2x + 2x is always 0.

so, g(x) + f(x) = g(x) + 0 = g(x) = 2x.

long proof :

g(x) + f(x) = 2x + -2x + 2x = 2x

Answer:

300%

Step-by-step explanation:

To find percent change we need to use this formula:

\(change = \frac{Amount of change}{Original} * 100\)

To find the amount of change we need to minus 50 from 200:

200 - 50 = 150

Now that we have the amount of change we can plug it in to the equation with the original amount (50):

\(change = \frac{150}{50} = 3 * 100 = 300\)

Therefore, the percent of change is 300%.
