Analyze the function’s graph to determine which statement is true.

zalisa [80]

Let us examine the given statements:

1. Over the interval [-2.5, 0.5], the local maximum is 2.
TRUE

2. As the x-values go to positive infinity, the function's values go to
negative infinity.
The opposite happens.
FALSE

3. The function is decreasing over the interval (-1, 0.75).
The function decreases in (-1, 0), but it increases in (0, 0.75).
FALSE

4. The function is negative for the interval [-2, 0].
The function is positive in [-2, -1). It is negative only in (-1, 0].
FALSE

Pleaseee help me this is gonna be due in a little and I need help bad it’s pretty algebra

Anarel [89]

Answer:

a.) .375 inches per day

b.) no

c.) 48 days

Step-by-step explanation:

If 8 days produces 3 inches of ice, I divided the 3 inches by the 8 days to see how much it grew per day. I got .375 inches per day.

Knowing how much it grew each day, I used .375 inches per day and multiplied it by 21 (3 weeks). So no, it only grew 7.875 inches over the 21 days.

You can double check it by dividing 10 inches / .375 inches per day and saw it would take over 26 days to reach 10 inches.

I took 1.5 feet and converted it to 18 inches. 18 inches divided by .375 inches per day equals 48 days.

I hope this helps you! :)

A radioactive isotope has a half life of 4.51 days. If 12.63 grams are now present, how much will be left after 15

Marizza181 [45]

Answer:

Step-by-step explanation:

$f=ir^t\\ \\ \frac{1}{2}=r^{4.51}\\ \\ ln(0.5)=4.51lnr\\ \\ r=e^{\frac{ln0.5}{4.51}}\\ \\ r\approx 0.8575\\ \\ f(15)=12.63(0.8575^{15}\\ \\ f(15)\approx 1.26g$

The management of Ditton Industries has determined that the daily marginal revenue function associated with selling x units of t

barxatty [35]

Answer:

(a) The daily total revenue realized from the sale of 210 units of the toaster oven is $6,195.

(b) The additional revenue realized when the production (and sales) level is increased from 210 to 310 units is $1,400.

Step-by-step explanation:

The marginal revenue gives the actual revenue realized from the sale of an additional unit of the commodity given that sales are already at a certain level. The derivative R' of the function R measures the rate of change of the revenue function.

We know that the daily marginal revenue function is given by

$R'(x) = -0.1x+40$

(a) To find the the daily total revenue you must:

Integrate the daily marginal revenue function,

$\int R'(x)dx = \int(-0.1x+40)dx\\\\R(x)=-\int \:0.1xdx+\int \:40dx\\\\R(x)=-0.05x^2+40x+C$ ,

where C is a constant.

Find the value of C, using the fact that if you sell 0 units your daily revenue is $0.

$0=-0.05(0)^2+40(0)+C\\C=0$

$R(x)=-0.05x^2+40x$

The daily total revenue realized from the sale of 210 units of the toaster oven is

x = 210 units

$R(210)=-0.05(210)^2+40(210)\\R(210)=-210^2\cdot \:0.05+8400\\R(210)=-2205+8400\\R(210)=6195$

(b) To find the additional revenue realized when the production (and sales) level is increased from 210 to 310 units you must:

Find the daily total revenue realized from the sale of 310 units

$R(310)=-0.05(310)^2+40(310)\\R(310)=-310^2\cdot \:0.05+12400\\R(310)=-4805+12400\\R(310)=7595$

The additional revenue realized when the production (and sales) level is increased from 210 to 310 units is

$R(310)-R(210)=7595-6195=1400$
