Answer:
3:53 P.M. (15:53)
Step-by-step explanation:
x + 52 + 42 = the time (5:27 pm)
First we try to remove the extra minutes from 5:27pm
42 min (the second part of the fight) - 27 (the minutes from 5:27 pm) = 15
Now we have 15 minutes to take away and 60 minutes from 5pm
60 (5pm) - 15 = 45
Now once again we remove the extra minutes
52-45 (4:45pm) = 7
Then we take away the 7 minutes from 4pm
60 (4pm)- 7= 53

Answer:
y = 0.06x(20 -x)y = 5√(x+5) +4y = (x -9)^2 -76; (9, -76); 9±√76; 5Step-by-step explanation:
1.If we assume the ball was kicked from the origin and that it follows a parabolic curve, the equation can be written ...
y = -kx(x -20)
for some value of k that makes the maximum be 6. The maximum will occur at the value of x that is halfway between the points where the ball is on the ground, so at x=10. Then our value of k is such that ...
6 = k(10)(20 -10) = 100k
k = 6/100 = 0.06
The equation describing the ball's flight is ...
y = 0.06x(20 -x)
A graph is attached.
__
2.The translated square root function will have a vertical multiplier k that will make it pass through the given point. The parent function f(x) = √x can be translated so its vertex moves from (0, 0) to (-5, 4) by ...
g(x) = 4 +f(x+5)
Applying the scale factor k gives ...
g(x) = k·√(x +5) +4
We want g(20) = 29, so ...
29 = k·√(20 +5) +4
25 = 5k . . . . subtract 4
5 = k . . . . . . divide by 5
The equation of the function is ...
y = 5√(x +5) +4
__
3.We assume your "graphing form" is "vertex form", as that form is generally conducive to graphing.
We can complete the square by adding and subtracting the square of half the x-coefficient:
y = x^2 -18x +9^2 +5 -9^2
y = (x -9)^2 -76 . . . . . equation
vertex: (9, -76)
x-intercepts: 9±√76 ≈ {0.2822, 17.1778}
y-intercept: 5 . . . . (the constant in the given equation)
_____
Additional comment
When the quadratic is written in vertex form ...
y = a(x -h)^2 +k
the x-intercepts are h±√(-k/a).

Matthew wants to estimate the mean height of students attending his college. He records the heights of 100 randomly selected students attending the college. What is the population?
Select the correct answer below:
the mean height of the randomly selected students
the mean height of all students attending the college
the 100 randomly selected students
all the students attending the college
the heights of the randomly selected students
The correct option that shows the population of the research carried out by Matthew is;
Option D; all the students attending the college
We are told that Matthew wants to estimate the mean height of students attending his college.Now, let us say the total number of students in his college is x. If he decides to select 100 students randomly to record their height, it means this 100 students is a sample out of the total number of students which is x that is the population.
In conclusion, we can say that the population of this research by Matthew is the total number of students that attend the college.

the slope of tangent equals (y2 - y1) / (x2 - x1)
let the first point (x1 , y1 ) equals ( -1 , -2 )
and the second point (x2 , y2 ) equals (3 ,10)
so the slope equal (10+2)/(3+1) = 3
the equation is y-y1 =m(x-x1)
the answer is y+2=3(x+1)

The healthcare provider prescribes an IV solution of ampicillin 1 gram in 50 mL of DşW at 25 drops/minute. The nurse uses an infusion set that delivers 15 gtt/mL and starts the infusion at 1900. Using the 24-hour clock, what time should the nurse anticipate the infusion to be completed? (Enter numeric value only.)
The infusion will be completed at 19:31
The medicine that the nurse is giving the patient is 1 gram of ampicillin diluted in 50 mL of dextrose water.
This means 50 mL + 1 mL = 51 mL. 1 gram of ampicillin = 1 mL considering all water-based substances have a density of 1gm/mL.
Now, the set delivers 15 ggt or drops per mililiter. Let's calculate the total drops in the 51 mL.
51mL x 15ggt =765 drops
Finally, we know the medicine is given at a rate of 25 drops per minute. Let's calculate the time:
765 drops / 25 drops per minute = 30.6 minutesThis means the medicine it will take 30.6 minutes for the infusion to be completed and therefore the infusion will be completed at 19:31 (19:00 + 30.6 minutes = 19:30.6 or 19:31).

1. In a science lab, you collect the following sets of data. Which of the
four data sets are linear functions? If linear, determine the slope.
Answer:
data set: a ; slope: 1/2
Step-by-step explanation:
If an equation is linear, then the first common differences are all the same.
In table a:
17-12 = 5
22-17 = 5
27-22 = 5
etc.
Equation:
m represents slope
y = mx + b
y = mx + 12 (y-intercept is 12)
17 = 10m + 12
10m = 17-12
10m = 5
m = 10/5 = 1/2
