Designer Dolls, Inc., found that the number N of dolls sold varies directly with their advertising budget A and inversely with t
denis-greek [22]

here we are told that

number of dolls sold varies directly with advertising costs

number of dolls varies inversely with price of a doll


so initially

1800 dolls sold when advertising costs were $ 34 000

and price of a doll was $ 25


next they increased the advertising costs to $ 42 000

as we know number of dolls sold varies directly with advertising costs

so here when the advertising costs increase the number of dolls sold too should increases as its directly proportional relationship


we arent told that the price of a doll is changed so there's no effect on the number of dolls sold due to changes in price of a doll


only effect on number of dolls sold is due to increase in advertising costs

increase in advertising cost leads to increase in number of dolls sold


from the given options, only in one option the number of dolls sold are more than 1800 dolls. option is C with 2224 dolls


therefore correct answer is C. 2224 dolls

Pauley graphs the change in temperature of a glass of hot tea over time. He sees that the function appears to decrease quickly a
Mekhanik [1.2K]

Answer: We know that an "exponential growth" is that where a function start growing slowly and after start increasing more quickly.

a "logarithmic growth" is the opposite of this, at first you will see a quick increase, that after some time gets slower.

But in this case we are searching for decays: The decays are the opposite of the growths, an "logarithmic decay" starts slow and gets faster latter, and an "exponential decay" decreases very quickly at first, and latter more slowly.

Then, the model for the temperature of the hot tea over the time is a "exponential decay", this is a function of the form T(x) = T₀e^{-kt}, where T₀ is the initial temperature, t is the time, and k is a constant number.

Solve 4 - 2(-5a - 10)=30 and justify each step
Sergeeva-Olga [200]
First you would do parenthesis according to the PEMDAS(Parenthesis, Exponents, Multiply, Divide, Add, Subtract) Rule

4 -2(-5a -10) = 30

4 + 10a + 20 = 30

Now you need to add 4 and 20 because they are on the same side

24 + 10a = 30

Now subtract 24 on both sides

24 + 10a = 30

-24. -24


10a = 6

Last divide 10 from both sides


10a/10. = 6/10

a= 6/10

Last simplify (optional but recommended)

a = 3/5 or 0.6


Hope this helped :)

Help pls and no links
Svetlanka [38]

We know a or b != 0

but a-b==0 so both are the same unknown number

b/a must = 1

so

a/b is equivalent to b/a as a/b=1 as well.

So the last answer choice.
