a). 0.45 with a line over the 45 means 0.45454545454545... forever.

It's equivalent to 45/99 which is 5/11 .

b). 0.45 with a line over the 5 means 0.455555555... forever.

It's equivalent to (0.4 + 0.555555.../10)

The 0.4 part is 4/10

The 0.5555555555.../10 part is 5/90 .

(4/10) + (5/90) = 41/90

c). 0.45 means 45/100 . That's 9/20 .

If a population of 100 cells triples every hour, which function represents p(t), the population after t hours?

tia_tia [17]

Exponential functions are in the form $f(x)=a*b^x$ , where a is the initial value, b is the growth rate (percent increase) + 1, and x is the number of time periods. Our initial value is 100, and we're given the growth rate + 1 (tripling is the same as increasing by 200%; 200%=2.0; 2.0+1=3). Therefore our function is $p(t)=100*3^t$ .

Dan bought a truck for $29,800. The value of the truck depreciated at a constant rate per year. The table shows the value of the

leonid [27]

Answer:

A) f(t) = 29,800(0.89)^t

Step-by-step explanation:The truck value decreases by 11% each year.

The present value of the truck was $29,800.

29,800 x 0.11 = 3,728 dollars lost from value.

29,800 - 3,728 = 26,522, the value of the truck after one year.

26,522 x 0.11 = 2,917.42 cash lost from value.

26,522 - 3,728 = 23,604.58, the value of the truck after two years.

Therefore, the answer is A) f(t) = 29,800(0.89)^t.

$x {}^{2} - x - \frac{5}{2} = 0$
(1±√(1-4(1)(-5/2))/(2)

(1±√1+10)/(2)

$\frac{1 + \sqrt{11} }{2} \\ \frac{1 - \sqrt{11} }{2}$

aliya0001 [1]

Answer:

she needs to earn at least $200 more to equal $2,700, so

200=x($amount of needed sales) * .06

200/.06=x

$3,333=x is sales needed to meet goal

variable is $ amount of sales needed to earn $2,700 this month.

Commission rate as decimal=.06

Inequality that represents is...

x> or = $3,333
