On what interval is the function increasing.

Mathematics
1 answer:
LenaWriter [7]2 years ago
5 0
The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.

Solve the system of equations of equations by graphing on your calculator rounded to 3 decimal spaces
Vanyuwa [196]

Answer:

x=2.333\\y=-1,667  

Step-by-step explanation:

we have

y-x=-4 ----> equation A

2x+y=3 ----> equation B

Solve the system of equations by graphing

Remember that the solution of the system is the intersection point both graphs

Using a graphing tool

The intersection point is (2.333,-1.667)

see the attached figure

therefore

The solution is

x=2.333\\y=-1,667

Riley makes a mistake in step 2 while doing her homework. what was her mistake? startfraction x over x squared minus 5 x 6 endfr
maw [93]

The mathematical mistake that Riley made is that:
"She used the wrong common denominator." (Option A)

<h3>What is a Common Denominator?</h3>

A common denominator is a factor that is similar to all the fractions in the sequence of equations.

Hence the correct answer is:

(2(2x² - 6x + 9))/((x-3) (x-2) (x+3))

See the correct sequence of steps below:

Step One - the Expression is given as:

(x/(x-3)(x-2)) + (3/(x+3))

Step 2 - Find the common denominator and rewrite the expression so that the numerators are above the common denominators.

Hence we have:  (x (x+3) + 3(x-3) (x-2))/(x-3)(x-2)(x+3)

Step 3  Apply the Law of Multiplicative Distribution:

Hence we have  (x² +3x+3x²-9x-6x+16)/(x-3)(x-2)(x+3)

Step 4 -  Collect Like Items

This gives us: (x²+3x²)+(3x-9x-6x)+18/(x-3)(x-2)(x+3)

Step 5 Sort for like coefficients

This gives us:  ((1+3)x² +(3-9-6) * x + 18)/(x-3)(x-2)(x+3)

Step 6 -  check for the sum or difference

This gives us: (4x²+(3-9-6) * x+ 18)/(x-3)(x-2)(x+3)

We simplify and factor the expression to get

(2(2x²-6x+6)/(x-3)(x-2)(x+3).

You have agreed to loan some money to a friend at a simple interest rate of 180% which is outrageous but still about half of the
choli [55]

Answer:

the amount borrowed is ≅ $527

Step-by-step explanation:

Given that;

simple interest rate r = 180%  p.a

Let the amount borrowed (principal) be $x.

time t  = 4 weeks = 28 days

= 28/365 year

= 0.0767 year

we all know that :

Simple \ \  interest = \dfrac{P*r*t}{100}

Simple \ \  interest = \dfrac{x*180*0.0767}{100}

Simple interest = 0.13806x

Total amount to be paid after 4 weeks= Interest+Principal

= x + 0.13806x

= 1.13806x

Thus;

1.13806x = $600

x = $600/ 1.13806

x = $527.21

Hence; the amount borrowed is ≅ $527
