The cost C, in dollars, to have medical records transcribed is a function of time, t in hours. A physician's group spends C(t) =

Contact [7]

Answer:

B. $39550

Step-by-step explanation:

The expression for the function is not well-formatted, find the correct format in the solution bellow

Step one:

given data

We are told that the function of the cost is

$C(t) = 0.04t^3- 0.1t^2 + 5.5t$

instantaneous rate c(t) is the value obtained when we plug in 100 for t in the function above

substituting we have

$C(t) = 0.04(100)^3- 0.1(100)^2 + 5.5(100)\\\\\C(t) = 0.04*1000000- 0.1*10000 + 5.5*100\\\\C(t) = 40000-1000+550\\\\C(t) = 39550$

Y+1=2/5(x+3) in standard form?

Rzqust [24]

For this case we have that by definition, the equation of a line in the standard form is given by:

$ax + by = c$

According to the statement we have the following equation of the line:

$y + 1 = \frac {2} {5} (x + 3)$

We manipulate algebraically to write in the standard form. To do this we follow the steps below:

We apply distributive property on the right side of the equation: $y + 1 = \frac {2} {5} x + \frac {6} {5}$

We subtract $\frac {6} {5}$ on both sides of the equation:

$y + 1- \frac {6} {5} = \frac {2} {5} x\\y- \frac {1} {5} = \frac {2} {5} x$

We multiply by 5 on both sides of the equation:

$5y-1 = 2x$

We subtract 5y on both sides of the equation:

$2x-5y = -1$

Finally, the equation in its standard form is:

$2x-5y = -1$

Answer:

$2x-5y = -1$

Find the sum of the sequence: 108, 105, 102,...,15

Gre4nikov [31]

Answer:

1968

Step-by-step explanation:

The given sequence is a finite arithmetic sequence.

Step 1: Determine the number of terms in the sequence

For an arithmetic sequence, the nth term:

A(n)=a+(n-1)d

In the sequence:

First term, a=108
Last term, l=15
Common difference, d=105-108= -3

Therefore, to find which term the number 15 is, we have:

15=108+(n-1)(-3)

15=108-3n+3

15=111-3n

3n=111-15

3n=96

Number of terms in the sequence, n=32

Step 2: Find the sum of the sequence

For an arithmetic sequence with a given first and last term:

$Sum, S(n)=\frac{n}{2}(a+l)\\ =\frac{32}{2}(108+15)\\=16*123\\$Sum of the sequence, S(n)=1968$

On Sunday Sheldon bought 4 1/2 kg of plant food. He used 1 2/3 kg of plant food on his strawberry plants and used 1/4 kg of plan

abruzzese [7]

Answer:

27/12 KG

Step-by-step explanation:

On Sunday, Sheldon bought 4 1/2 kg of plant food. He used 1 2/3 kg on his strawberry plants and used 1/4 kg on his tomato plants. How many kilograms of plant food did Sheldon have left?

41/2 - (12/3 + 1/4)

$1\frac{2}{3} + \frac{1}{4}$

$1\frac{8 + 3}{12}$ = 1 11/12

$4\frac{1}{2} - 1\frac{11}{12}$

$3\frac{6-11}{12}$ = 2 7/12
