Nataly_w [17]

M=dc/dp=4/6=4/6=2/3

c(p)=2p/3 +b using (6,4)

4=2(6)/3+b

4=4+b, b=0 so

c(p)=2p/3

(the number of cherries needed as a function of the number of pies)

Find all real and non-real roots of the function ƒ(x) = x2 + 49. Question 1 options: A) x = –7, 7 B) x = –7i, 7i C) x = –49i, 49

dimulka [17.4K]

Answer:

Step-by-step explanation:

f(x) = x²+49 , rewrite the equation

x² +7² =0 , to find the roots make f(x) =0 and subtract 7² from both sides

x² = -7², square root both sides

√x² =√-7², consider √-1 =i

x= ±7i

the roots are -7i and 7i

Mary McDonald makes mugs in Miami. She makes two sizes of mugs: a small mug that she sells for $2.50 and a large mug that she se

IrinaVladis [17]

Mary McDonald sold 11 small mugs and 10 large mugs.

Step-by-step explanation:

Given,

Total cost of sold cups = $85

Cost of one small cup = $2.50

Cost of one large cup = $5.75

Cups at the start of day = 215

Cups at the end of day = 194

Cups sold = Cups at the start of day - Cups at end of day

Cups sold = 215 - 194 = 21

Let,

x represents the number of small cups.

y represents the number of large cups.

According to given statement;

x+y=21 Eqn 1

2.50x+5.75y=85 Eqn 2

Multiplying Eqn 1 by 2.50

$2.50(x+y=21)\\2.50x+2.50y=52.50\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(2.50x+5.75y)-(2.50x+2.50y)=85-52.50\\2.50x+5.75y-2.50x-2.50y=32.50\\3.25y=32.50$

Dividing both sides by 3.25

$\frac{3.25y}{3.25}=\frac{32.50}{3.25}\\y=10$

Putting in Eqn 1

$x+10=21\\x=21-10\\x=11$

Mary McDonald sold 11 small mugs and 10 large mugs.
