89.75 scooter:7 1/4% tax
eduard
The question is find the total cost when the price is $89.75 and the tax is 7 1/4%

Total cost = price + tax

Tax  = 7  1/4 % of price

Tax rate = [7 + 1/4] = 7.25 %

Tax = 7.25 % * price = 7.25 % * $89.75 = $[7.25/100] * 89.75 = $6.51

Total cost = $89.75 + $ 6.51 = $96.26

How do you do series with an n
SOVA2 [1]
The problem can be solved step by step, if we know certain basic rules of summation.  Following rules assume summation limits are identical.
\sum{a+b}=\sum{a}+\sum{b}
\sum{kx}=k\sum{x}
\sum_{r=1}^n{1}=n
\sum_{r=1}^n{r}=n(n+1)/2

Armed with the above rules, we can split up the summation into simple terms:
\sum_{r=1}^n{40r-21n+8}=n
=40\sum_{r=1}^n{r}-21n\sum_{r=1}^n{1}+8\sum_{r=1}^n{1}
=40\frac{n(n+1)}{2}-21n^2+8n
=20n(n+1)-21n^2+8n
=28n-n^2

=> (a) f(x)=28n-n^2
=> f'(x)=28-2n 
=> at f'(x)=0 => x=14
Since f''(x)=-2 <0  therefore f(14) is a maximum
(b) f(x) is a maximum when n=14

(c) the maximum value of f(x) is f(14)=196

HELP PLEASE SHOW STEPS I HAVE NO IDEA WHAT TO DO. I HAVE BEEN TRYING TO FIGURE IT OUT BUT I CAN’T.
weqwewe [10]

Answer: x^{2} +23x+49

Step-by-step explanation:

To find the area of the shaded region, you must find the area of the larger rectangle [(x+10)×(2x+5)] and subtract the area of the smaller rectangle [(x+1)×(x+1)] from it.

First, you simplify the larger rectangle's area:

(x+10)×(2x+5) = 2x^{2} +25x+50

Then, simplify the smaller rectangle's area:

(x+1)×(x+1) = x^{2} +2x+1

Finally, subtract the smaller rectangle's area from the larger rectangle's area:

(2x^{2} +25x+50) - (x^{2} +2x+1) = x^{2} +23x+49

Therefore, the final answer is x^{2} +23x+49.

I hope this helps!

kkurt [141]

Answer:

1

Step-by-step explanation:

To find x, set both equations equal to each other.

\sqrt{x}  =   \sqrt{5x - 4}

( { \sqrt{x} })^{2}  =  ({ \sqrt{5x - 4} })^{2}

x = 5x - 4

x - 5x = 5x - 5x - 4

- 4x =  - 4

- 4x \div  - 4 =  - 4 \div  - 4

x = 1
