Answer:
The y-intercept in coordinate form is (0, 2.9), which the y-intercept represents the pickup fee which is $2.90 before any mileage
Step-by-step explanation:
Hello, I do apologize that no one responded for two hours.
1 - Understanding what it means to be a y-intercept
When mathematics presents the "y-intercept" its the unimaginative way of saying "Where the equation crosses the y-axis"
Looking at a graph we can deduce that, the y axis in traditional graphs is always at the x value of 0.
What can this mean for this situation?
We want to find out how much each person with 0 miles or no miles driven.
This will be our pickup fee alone
How can we do this?
Theres multiple ways, however the way I like is to set an equation to zero.
2 - Slope Intercept Form
We need to get it into the slope-intercept form using data given to us to use as our equation.
For reference the slope-intercept form is
y = mx + b
y = y value
m = slope
x = x value
b = y - intercept
2.1 - Find the slope
for y = mx + b we'll need to find our slope, m, and to do so we use the following formula
[tex]slope = m = \frac{\triangle y}{\triangle x} = \frac{change~in~y}{chnage~in~x} = \frac{y_2 ~ - ~ y_1}{x_2 ~ - ~ x_1}[/tex]
To do this we need to assign x values and y values.
Our total cost is our y value, because its a total, and our variable is x which will be our miles.
(x value is always the variable, and our y value is always the totals)
So now looking at the data;
Gus;
$12.00 for a 6.5-mile journey
Tony;
$15.50 for a 9-mile journey
We can deduce at 6.5 miles we'll pay $12, and at 9 miles we'll pay $15.50
Because 6.5 is less than 9 our x1 and y1 will be deduced from that, and with that in mind, let's solve that equation.
POINT → (x, y)
(6.5, 12)
(9, 15.50)
[tex]\frac{y_2 ~ - ~ y_1}{x_2 ~ - ~ x_1} = \frac{15.50 ~ - ~ 12.00}{9 ~ - ~ 6.5} = \frac{3.5}{2.5} = 1.4[/tex]
Our slope is 7/5, so therefore,
y = mx + b
=
y = 1.4x + b
2.2 - Plug and chug to find our y-intercept, b.
We'll need to plug in a point into the unfinished equation to solve for b
y = 7/5x + b
In this instance let's use (6.5, 12)
(x, y)
12 = 1.4(6.5) + b
12 = 9.1 + b
-9.1 -9.1
2.9 = b
Lets plug that in to our y = mx + b
y = 1.4x + b
↓
y = 1.4x + 2.9
And would you look at that, just by setting up the equation we now know our y-intercept, now if you recall from earlier one of my notes said this:
POINT → (x, y)
This is the same thing as coordinate form I'm assuming, and as a result, we have all the information we need to answer the problem.
3 - Putting it together to answer the problem
POINT → (x, y)
=
Coordinate Form:
=
(x, y)
Now remembering what I said earlier, the y-axis, is always on x = 0
So our y-intercept in coordinate form is;
(0, 2.9)
This means;
The pickup fee is $2.90 which excludes any mileage.
See the answer for it put together

Step-by-step explanation:
The decibel level of the sound of a monster truck is
Further explanation:
Decibel is defined as a unit which is used to measure the relative loudness or intensity of the sound.
In the question it is given that the intensity of the sound of a monster truck is watts per square inch.
The formula which is used to calculate the decibel level of a sound is as follows:
Here, represents the intensity of the sound of a monster truck and represents the threshold intensity of hearing at .
The value of the threshold intensity of hearing at is watts per square meter.
This implies that the valiue of is watts per square meter.
The intensity of the sound of a monster is given in unit of per square inch.
The relation between per square inch and per square meter is as follows:
So, the intensity of a monster truck is converted into per square meter as follows:
This implies that the value of is watts per square meter.
Now, substitute the value of and in the equation .
The approximated value of the above equation is as follows:
From the above calculation it is concluded that the decibel level of the sound of a monster truck is .

Find the volume of a hemisphere with a radius of 8. Round to the nearest tenth.
Answer:
V(hemisphere) = 1072.3in^3
Step-by-step explanation:
To find the volume of a hemisphere, we will have to take the volume of a sphere as a whole and divide it by 2. This is because a hemisphere is half of a sphere.
The volume of a sphere is:
[tex]V(sphere) = \frac{4}{3} \pi r^3[/tex]
Let's plug in the radium of 8 into the equation and solve:
[tex]V(sphere) = \frac{4}{3} \pi (8)^3\\V(sphere) = \frac{4}{3}\pi 512 \\V(sphere) = 2144.660585[/tex]
Now, divide it by 2
V(sphere) = (2144.660585)/2
V(hemisphere) = 1072.3in^3
I hope this helps!!

3.Solve: 12 = -4h + 7 +11h
Which of the following would be an appropriate first step to take in solving for "h"?
Group of answer choices
adding 7 to both sides
adding 12 to both sides
combining (-4h) and (11h)
multiplying both side by 4
Answer:
$3.21
Step-by-step explanation:
Answer:
1: $3.21.
2: 50x+120=300
3: h=5/7/ first step would be to adding 7 to both sides.
Step-by-step explanation:
for the 3rd:
you're combining like terms so you have to subtract 7 from both sides you gotta subtract 12-7 so that gives you 5=7h+7-7 and the subtract the 7-7, and that will give you 0 so you have 5=7h left.divide both sides by the same terms (7), so you'll have 5/7 and 7h/7 so 7/7=0 so you drop that and just have the h. now switch sides with the virable and the fraction you still have (5/7)you now have h=5/7.apply the product rules to determine the signof each expression

Sam spent $1.08 to make 18 copies at office max.At that rate how much will he pay to make 40 copies?
Answer:
$2.40
Step-by-step explanation:
If we know it is $1.08 to make 18 copies. We can do the math to find the rate of 1 copy. This would be by doing 1.08/18=0.06. So, it costs $0.06 to make 1 copy. Now, multiply that by 40 copies 0.06x40=2.40. The cost of 40 copies is $2.40.
