Factoring the denominator we get (x -6)(x+4), therefore x = 6 and x = -4
These two values would make the rational expression undefined.

I need to find the measure of angle LMN.
sergiy2304 [10]
Notice the circle, the radius NM or ML is 5, and the arc the angle makes is 14.3 cm, thus

\bf \textit{arc's legnth}\\\\
s=\cfrac{\pi \theta r}{180}\quad 
\begin{cases}
r=5\\
s=14.3\\
\theta =angle~in\\
\qquad degrees
\end{cases}\implies 14.3=\cfrac{\pi \theta 5}{180}\implies \cfrac{14.3\cdot 180}{5\pi }=\theta

Write a function that is passed in a positive integer, n, and sum up all the digits from 1 to n, doubling the even numbers. In o
olya-2409 [2.1K]

Answer:

Written in Python

def sums(n):

    total = 0

    for i in range(1,n+1):

         if i%2 == 0:

              total = total + i*2

         else:

              total = total + i

    return(total)

Step-by-step explanation:

The function is written in Python

def sums(n):

This initializes total to 0

    total = 0

This iterates through the integers that makes up n i.e. 1,2,3.....n

    for i in range(1,n+1):

This checks if current digit is even

         if i%2 == 0:

If yes, it adds the double of the digit

              total = total + i*2

         else:

If otherwise, it adds the digit

              total = total + i

This prints the calculated sum or total

    return(total)

To call the function from main, use the following:

print(sums(n))

Where n is a positive integer. i.e. n \geq 1

Mike forgot to replace the cap on a bottle of room freshener. The room freshener began to evaporate at the rate of 15% per day.
riadik2000 [5.3K]
Percentages are out of 100. So we'll multiply by 0.85 to represent the 15%

To find the y points on the graph we can use f(x) = 0.85^x*40

We'll input 1-5 for x to find y:

1:  0.85^1=0.85*40=34
2: 0.85^2=0.7225*40=28.9
3: 0.85^3=0.614125*40=24.57
4: 0.85^4= 0.52200625*40=20.88
5: 0.85^5=0.443705312*40=17.75

Therefore the answer is a graph of exponential function going down from left to right in quadrant 1 through the point 0, 40 and approaching the x-axis.
