Answer 1
Answer:
Below.
Step-by-step explanation:
You haven't sent the graphs.
y - 3 = 3/2(x - 4)
y - 3 = 3/2x - 6
y = 3/2x - 3
- this is the slope intercept form of the graph.
It will be a straight line which rises to the right and passes through the y axis where y = -3. Also it has a slope of 3/2.
Wne y = 0 x = 2 so it passes through the x-axis at x = 2.

Answer:
Use tan trig ratio:
[tex]\sf tan(\theta)=\dfrac{O}{A}[/tex]
where [tex]\theta[/tex] is the angle, O is the side opposite the angle, and A is the side adjacent the angle
Given:
[tex]\theta[/tex] = 39°O = 10[tex]x[/tex] = A
Substituting these values into the formula:
[tex]\implies \tan(39)=\dfrac{10}{x}[/tex]
Multiplying both sides by [tex]x[/tex]:
[tex]\implies x\tan(39)=10[/tex]
Dividing both sides by [tex]\tan(39)[/tex] :
[tex]\implies x=\dfrac{10}{\tan(39)}[/tex]

How much, in total, did Noel spend to cash her three most recent paychecks?
Answers
The total amount of money that was spent by Noel to cash her three (3) most recent paychecks is equal to $10.99.
What is a paycheck?
A paycheck can be defined as a financial document that is issued by an employer to an employee as payment for the work done over a period of time.
How to calculate the amount spent.
From the table, we can see that the amount of money charged by the bank as check processing fee is equal to $1.99, as well as 1.99% (0.0199) of the amount being cashed by a customer.
Thus, we would compute the amount of money spent by Noel as follows:
Noel = (0.0199 × 100.53) + (0.0199 × 119.38) + (0.0199 × 122.52) + (1.39 × 3)
Noel = 2.00 + 2.38 + 2.44 + 4.17
Noel = $10.99.

Answer: y = 12.5x
Step-by-step explanation:
Because 250 bottles are filled every 20 minutes:
250/20=12.5
So, x=1, y=12.5
Hence, x=2 y=25
Because the number of bottles is directly proportional to the operation of the machine so:
12.5=a+b, 25.2a+b
a=12.5, b=0
Therefore, the equation is y = 12.5x
The Desmos graph of y = 12.5x is attached below

Use the right triangular prism to find the total surface area of the prism. Leave label off answer.
Answers
Step-by-step explanation:
the total surface area is the sum of the 5 individual areas in the surface :
2 triangle sides (left and right).
1 back rectangle side
1 rectangle floor
1 inclined rectangle front side
to get the length of the baseline (Hypotenuse) of the right-angled triangles on the side. we use Pythagoras
c² = a² + b²
where c is the Hypotenuse (the side opposite of the 90° angle).
c² = 3² + 4² = 9 + 16 = 25
c = 5
so, now, we have everything we need.
the area of a triangle side (since it is right-angled) :
4×3/2 = 6
2 sides, that makes 12
the area of the back side
6×3 = 18
the area of the floor
6×4 = 24
the area of the inclined front side
6×5 = 30
so, the total surface area is
12+18+24+30 = 84
