6 0

Answer:

Step-by-step explanation:

126 + 44 = 170 ( total for under 25s)

186 - 56 = 130 (online for 25s - 50s)

154 - 58 = 96 ( in stores for aboves 50s)

314 for ONLINE TOTAL

196 for IN STORES TOTAL

510 for TOTAL TOTAL

A = 170

B = 56

C = 96

D = 96 - 58 = 38

E = 314 - 196 = 118

F = 510

creativ13 [48]

Answer: 10 cents

Step-by-step explanation:

First find the unit rate of each item.

$42.60 divided by 100= 0.426

$32.60 divided by 100= 0.326

Then find the difference

0.426 minus 0.326= 0.1 or 10 cents.

A function f is described by f(x)=A*exp(kx)+B, where A, B and k are constants. Given f(0)=1, f(1)=2, and that the horizontal asy
s2008m [1.1K]

Answer:

k = ln (6/5)

Step-by-step explanation:

for

f(x)=A*exp(kx)+B

since f(0)=1, f(1)=2

f(0)= A*exp(k*0)+B = A+B = 1

f(1) = A*exp(k*1)+B =  A*e^k + B = 2

assuming k>0 , the horizontal asymptote H of f(x) is

H= limit f(x) , when x→ (-∞)

when x→ (-∞) , limit f(x) =  limit (A*exp(kx)+B) = A* limit [exp(kx)]+B* limit = A*0 + B = B

since

H= B = (-4)

then

A+B = 1 → A=1-B = 1 -(-4) = 5

then

A*e^k + B = 2

5*e^k + (-4) = 2

k = ln (6/5)    ,

then our assumption is right and k = ln (6/5)

mindy is 3 years older than two times her brother jake’s age. let j represent jake’s age and m represent mindy's age. which equa
horrorfan [7]
Okay so, it would be

<span>2*j+3 = m
( jake's age times 2 in order to represent being 2 years older, however... Mindy is 3 more years old than the product of that expression. This would add 3.)

So, C? m = 2j + 3
