Answer:
The final cost for him is;

Explanation:
Given that the ipod costs $220;

The store gives a 35% discount, which means he will only pay 65% of the original cost;

The store price is;

Also he will need to pay additional 8% sales tax on the discounted price P;

The final cost he need to pay is the sum of the discounted price and the sales tax;

Therefore, the final cost for him is;
Answer:
Ou seja, nesse caso, 15 reais para cada uma, escrevendo de uma maneira mais simples:
" 15 para as duas"
E assim obtemos a resposta, a letra b) 1:45, pois são 15 para as duas.
Step-by-step explanation:
Answer:
f(x)=11+7√x
f'(x)=7/(2x^(1/2))
putting x=1
f'(1) = 7/(2×1^(1/2))
= 7/2 = 3.5
putting x=2
f'(2) = 7/(2×2^(1/2))
= 7/(2×√2)
= 7√2/4
= 2.47 (rounded to the nearest hundredth)
f'(3) = 7/(2×3^(1/2))
= 7/(2×√3)
= 7√3/6
= 2.02 (rounded to the nearest hundredth)
Answer:
-5/16
Step-by-step explanation:
multiply 4*2
4 * 2= 8 -16x -13
8-16x-13
add like-terms
8-13=-5
-5-16x=0
move the 5 with 0, which will make it positive
-16x=5
Divide
5/-16 =x
The slope of the line represents that the remainder of the goal decrease by 8 for each card sold.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the slope of the line and b is the y intercept.
The line passes through the point (1, 8) and (2, 16), hence:

The equation of the line is given by y =8x
