Answer:
let t be winning time t < 7.09 seconds
Step-by-step explanation:
let's first order the times from least to greatest:
7.09, 7.40, 7.75, and 7.86
Now, in order to have the winning time, the last runner must have a time less than the fastest runner so far. So, the winning time is less than 7.09 seconds.

Many doctors rely on the use of intravenous medication administration in order to achieve an immediate response of a particular drug's effects. The concentration, C, in mg/L, of a particular medication after being injected into a patient can be given by the function C of t is equal to the quantity negative 10 times t squared plus 50 times t end quantity over the quantity t squared plus 4 times t plus 3 end quantity comma where the time, t, is hours after injection. Part A: What is the domain of the function C(t) based on the context of the problem? Show all necessary calculations. (5 points) Part B: Graph the function to determine the greatest concentration of the medication that a patient will have in their body. (5 points)
Graphs are used to show the relationship between variables, where the variables are represented by a pair of axes.
The domain of the function is [tex]t \ge 0[/tex] The greatest concentration of the medication is 5mg/LGiven that:
[tex]C(t) = \frac{-10t^2 + 50t}{t^2 + 4t + 3 }[/tex]
(a): The domain of the function
Because the medication concentration C(t) is a function of time (t), the domain is the possible values t can take.
t, cannot take negative values (i.e. it is not possible to have a negative time).
The least possible value of t is 0
So, the domain of the function based on the context is:
[tex]t \ge 0[/tex]
(b) The greatest concentration of the medication
From the graph (see attachment), the maximum y-value is 5.
Hence, the greatest concentration of the medication is 5 mg/L

In triangle ABC, m ZA = 47°, m ZB = 62°. m ZC =
a. 81°
b. 61°
C. 71
d. 51°
Answer:
m ZC = 71 degrees. Option C.
Step-by-step explanation:
Triangles always measure a total of 180 degrees.
47 + 62 + c = 180
109 + c = 180
c = 71
Answer:
71°
Step-by-step explanation:
The total angles in a triangle should equal 180°
a + b + c = 180
47 + 62 + c = 180
109 + c = 180
180 - 109 = 71
c = 71°

Answer:
19, 25, 32
Step-by-step explanation:
Find the difference within each number:
5 -> 7: + 2
7 -> 10: + 3
10 -> 14: + 4
With each difference, + 1 is added so we can infer the next difference will be + 5.
14 + 5 = 19
Next is + 6.
19 + 6 = 25
Now + 7.
25 + 7 = 32

Please find the value of x and y. It's in angle addition postulate so if you know how to solve these please help.
Answer:
see explanation
Step-by-step explanation:
(7)
(25x + 8) and (9x + 2) are adjacent angles and sum to 180° , then
25x + 8 + 9x + 2 = 180 , that is
34x + 10 = 180 ( subtract 10 from both sides )
34x = 170 ( divide both sides by 34 )
x = 5
Then
9x + 2 = 9(5) + 2 = 45 + 2 = 47
(7y + 5) and (9x + 2) are vertical angles and are congruent , so
7y + 5 = 47 ( subtract 5 from both sides )
7y = 42 ( divide both sides by 7 )
y = 6
------------------------------------------------------
(8)
(11x - 24) and (7x + 30) are vertical angles and are congruent, so
11x - 24 = 7x + 30 ( subtract 7x from both sides )
4x - 24 = 30 ( add 24 to both sides )
4x = 54 ( divide both sides by 4 )
x = 13.5
Similarly
(17y - 4) and (5y + 38) are vertical angles and congruent , then
17y - 4 = 5y + 38 ( subtract 5y from both sides )
12y - 4 = 38 ( add 4 to both sides )
12y = 42 ( divide both sides by 12 )
y = 3.5

Jasper Hall sells farm chemicals. He is paid a commission of 99% of his first $6,000 in sales during the month and 14% on all sales over $6,000. What is his commission in a month in which he has sales worth $16,120?
Amount of total commission is $1,956.8 (Approx.)
Given:
Percent of commission upto $6,000 sale = 9% (Misprint)
Percent of commission over $6,000 sale = 14%
Amount of total sales = $16,120
Find:
Amount of total commission
Computation:
Amount of commission upto $6,000 sale = 6000 × 9%
Amount of commission upto $6,000 sale = $540
Amount remain = 16120 - 6000
Amount of commission upto $6,000 sale = $10,120
Amount of commission over $6,000 sale = 10,1200 × 14%
Amount of commission over $6,000 sale = $1,416.8
Amount of total commission = Amount of commission upto $6,000 sale + Amount of commission over $6,000 sale
Amount of total commission = 540 + 1,416.8
Amount of total commission = 1956.8
Amount of total commission = $1,956.8 (Approx.)

What is the volume, in ml, of 100. grams of mercury? Mercury has a density of 13.54 g/mL
(which means 1mL=13.54 g).
13.54 g/mL = (100 g)/v
==> v = (100 g)/(13.54 g/mL) = 7.39 mL
The volume of 100 grams of mercury is 7.38 mL when the density of mercury is 13.54 g/mL.
To calculate the volume of 100 grams of mercury, we can use the density formula:
Density = Mass / Volume
We are given the density of mercury as 13.54 g/mL, and we want to find the volume in mL.
Volume = Mass / Density
Substituting the given values:
Volume = 100 g / 13.54 g/mL
Simplifying the division:
Volume= 7.38 mL
Therefore, the volume of 100 grams of mercury is 7.38 mL.
