the concentration of a drug in a patient's bloodstream t hours after the drug was administrated presented by the equation c(t) =
Andrews [41]

The graph of the function has no asymptotes.

<h3>The table of values of c(t)</h3>

The function is given as:

c(t) = 5t - t² + 1

When t = 1, 2, 5, 10;

We have:

c(1) = 5(1) - 1² + 1 = 5

c(2) = 5(2) - 2² + 1 = 7

c(5) = 5(5) - 5² + 1 = 1

c(10) = 5(10) - 10² + 1 = -49

So, the table of values is

t        c(t)

1         5

2        7

5        1

10      -49

See attachment for the graph of the function

<u>The domain</u>

From the question, we understand that t represents time.

  • Time cannot be negative i.e. t ≥ 0
  • The time does not exceed 5.2 i.e. t ≤ 5.2

So, the domain is 0 ≤ t ≤ 5.2

<u>The range</u>

From the graph, the maximum of the graph is 7.25

So, the range is 0 ≤ f(t) ≤ 7.25

<u>Asymptotes</u>

From the graph, we can see that the graph has no asymptotes.

Find the value of x. then tell whether the side lengths form a Pythagorean triple
timurjin [86]

Answer:

x = √226

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

In that case, plug in <em>a </em>and <em>b</em>,

15² + 1² = c²

c = √(15² + 1²)

c = 15.0333

This is NOT a Pythagorean triple.

Find the remainder when f(x) is divided by (x - k) <br> f(x) = 5x4 + 8x3 + 4x2 - 5x + 67; k = 2
yan [13]

It is to be solved by reminder thorem
f(x)/(x-k) will have reminder f(k), 
so, f(2) = 5*(2^4) + 8 *(2^3) +4* (2^2) -5(2) +67

             =5*16 + 8*8 +4*4 -5*2 +67
             =80 + 64 + 16 -10 +67

             = 217

Best answer gets brainliest​
Luden [163]
K= -3

3y = x+6 can be rewritten as y = 1/3x + 2
a perpendicular slope is the opposite reciprocal of the original slope
so instead of 1/3 it would be -3
therefore. k must equal -3 to be perpendicular to 3y = x+6
