Ann made a 33-step staircase using 1818 toothpicks as shown in the figure. How many toothpicks does she need to add to complete

malfutka [58]

You would take 1818÷33=55.09

55.09 is how many toothpicks it took for each step made

Then you would take 55.09×55=3029.95

You can make sure this is correct by taking 55.09×33=1817.97 which would actually be 1818 because you had to round it up

Find the radius of convergence, R, of the series. ∞ (−1)n (x − 6)n 4n + 1 n = 0 R =

Rina8888 [55]

I'm guessing the series is

$\displaystyle\sum_{n=0}^\infty\frac{(-1)^n(x-6)^n}{4n+1}$

Use the ratio test: we have

$\displaystyle\lim_{n\to\infty}\left|\frac{\frac{(-1)^{n+1}(x-6)^{n+1}}{4n+5}}{\frac{(-1)^n(x-6)^n}{4n+1}}\right|=|x-6|\lim_{n\to\infty}\left|\frac{4n+1}{4n+5}\right|=|x-6|$

The series converges for

$|x-6|$

which has a radius of convergence of 1.

Identify the slope and y-intercept of the line −2x+5y=−30.

guajiro [1.7K]

Answer:

slope = 2/5 , y-intercept = -30

Step-by-step explanation:

-2x + 5y = -30

5y = 2x - 30

y = 2/5x - 6

we know that the general form is:

y = (slope)*x + (y- intercept)

so, from our equation, we can say that...

slope = 2/5

y- intercept = -30

Adwoa receive a commission of 20% on bread she sold.in one week,adwoa's commission was 540 ghana cedis how much bread did she se

Simora [160]

Adwoa sold x amount of bread during that week, where a is mathematically given as

x = 2700

This is further explained below.

<h3>What is a commission?</h3>

Generally, a payment made to a representative or employee in exchange for the completion of a transaction or the provision of a service, in particular: a predetermined share of the profits made from the whole sum, which is then distributed to the agent in charge of the company.

i) 20% × x = 540

Therefore

x = 540 × 100/20

x = 2700

In conclusion, During that particular week, Adwoa had a total sales volume of x, where x is denoted by the mathematical expression 2700.
