Answer:
$29.865
Step-by-step explanation:
Because 3.75/2 =1.875 so $1.875 plus $15 Plus the flat $12.99
Using a linear function, it is found that he spent $29.865 for the 4.5 hours he was on the river.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, we have that:
The intercept is the flat rate of $12.99.The slope is the cost per hour of $3.75.Hence the cost of x hours is given by:
C(x) = 12.99 + 3.75x.
For 4.5 hours, the cost is given as follows:
C(4.5) = 12.99 + 3.75(4.5) = $29.865.

augustin and edson are going to a baseball game to get to the stadium they travel east on the highway at 120km/hr for 30 minutes then they turn onto the stadium parkway and travel south at 60km/hr for 10 minutes assume their starting point is at the origin what is the position of the stadium
Answers
The position of the stadium, given the data is 60 Km east and 10 Km south
What is speed?Speed is the distance travelled per unit. Mathematically, it can be expressed as:
Speed = distance / time
With above formula, we can determine the position of the stadium. Details below
How to determine the distance travelled in 30 minutesTime = 30 minutes = 30 / 60 = 1/2 hourSpeed = 120 Km/hDistance =?Speed = distance / time
Cross multiply
Distance = speed × time
Distance = 120 × 1/2
Distance = 60 Km east
How to determine the distance travelled in 10 minutesTime = 10 minutes = 10 / 60 = 1/6 hourSpeed = 60 Km/hDistance =?Speed = distance / time
Cross multiply
Distance = speed × time
Distance = 60 × 1/6
Distance = 10 Km south
Thus, we can conclude that the position of the stadium is 60 Km east and 10 Km south

f has a range of (-infinaty, 7),
and a graph that is symmetric
about the line x = 3, and has a
Y-intercept of 4
Answers
Answer:
[tex]f(x)=-|x-3|+7[/tex]
Step-by-step explanation:
The parent function of an absolute function is the modulus function:
[tex]f(x)=|x|[/tex]
Graph of Modulus function:
(see 2nd attachment)
[tex]f(x)=|x|=\begin{cases} \textsf{\:\:\:$x$, \quad if $x\geq 0$}\\\textsf{$-x$, \quad if $ x < 0$} \end{cases}[/tex]
Its vertex is at the origin (0, 0).
Its line of symmetry is x = 0.
It opens upwards.
Given information:
Range: (-∞, 7)Axis of symmetry: x = 3y-intercept: (0, 4)The axis of symmetry is the x-value of the vertex of an absolute function.
The y-value of the range is the y-value of the vertex of an absolute function.
Therefore, the vertex of the absolute function f(x) is (3, 7).
Graphing
Plot the vertex at (3, 7) and the y-intercept at (0, 4).As the function f(x) has a range of (-∞, 7), it opens downwards. Draw a straight line through the y-intercept that terminates at the vertex.Draw a line that is symmetrical to this line.To find the equation of the absolute function, work out the series of transformations that take the parent function to the given function.
As the function f(x) has a range of (-∞, 7), it opens downwards. Therefore, the parent function has been reflected in the x-axis:
[tex]\implies -f(x)=-|x|[/tex]
As the function f(x) is symmetric about the line x=3, the parent function has been translated 3 units to the right:
[tex]\implies -f(x-3)=-|x-3|[/tex]
Finally, as the highest y-value of the function is y = 7, the y-value of its vertex is y = 7. Therefore, the parent function has been translated 7 units up:
[tex]\implies -f(x-3)+7=-|x-3|+7[/tex]
Therefore, the equation of the absolute function with the given parameters is:
[tex]f(x)=-|x-3|+7[/tex]

point A bisects LS BC. If LS BA=6x-3 and LS AC= 3x+7. Solve for X. PLS ANSWER QUICKLY!!!
Answers
Based on the bisection of line BC by point A, the value of x is 10/3
How to determine the value of x?The given parameters are:
Point A bisects BCBA = 6x - 3 AC= 3x + 7Because the point A bisects BC, then
BA = AC
Substitute the known values in the above equation
So, we have
6x - 3 = 3x + 7
Collect the like terms
6x - 3x = 3 + 7
Evaluate the like terms
3x = 10
Divide both sides of the equation by 3
x = 10/3
Hence, based on the bisection of line BC by point A, the value of x is 10/3

n = 1 is a counterexample for both the given equations.
Here, we are given two equations, let us look at them one by one-
a. (n + 5) / 5 = n + 1
let us take n = 1
the, (1 + 5) / 5 = 1 + 1
6/ 5 = 2
This equation does not hold as 6/5 ≠ 2. Thus, n = 1 doesn't satisfy the given equation and hence is a counterexample.

Circumference of circle or perimeter of the circle is that the measure of the boundary of the circle whereas the world of circle defines the region occupied by it which is given by A = πr² where "r" is the radius of the circle.If we tend to open a circle and create a line out of it, then its length is that the circumference which is given by C = 2πr where "r" is the radius of the circle.It's typically measured in units, like cm or unit m.It is given that area of the circular park is .02 square miles .
Using area formula , we get
0.02 = πr²
0.02 = 3.14r²
0.0063 = r²
0.079 = r

A circle is a locus (collection) of points that are a defined distance apart from one another. The fixed point and fixed distance are referred to as the "center" and "radius," respectively. A quarter-circle is one-quarter of a circle. As a result, the area of a quarter circle is one-fourth of the size of a full circle.

The time Emma should take for the run must be less than 15 minutes to bear her previous record.
What is referred as the inequality?The expression 5x - 4 > 2x + 3 resembles an equation, but the equals sign has been replaced through an arrowhead. It's an example of inequity. This means that the left part, 5x - 4, is larger than the right part, 2x + 3. We'll be looking for x values where the inequality holds true.Emma's previous record was 1 hour and 10 minutes. This is equivalent to
60+10 minutes equals 70 minutes.
She already has run 55 minutes;
So, let us consider the remaining time, x, added to 55, must be less than 70 to overcome her previous time:
x + 55 < 70
The inequality is obtained.
Subtract 55 from each side:
