Answer:
-6/-11
Step-by-step explanation:
First we find the gradient.
Which is defined by the formula, y2-y1/x2-x1
In the coordinates given, y2= -1 y1= 5 x2= -4 x1=7
-1-5/-4-7 = -6.75 (this is the slope / gradient)
Therefore it is -6/-11

An inverted conical water tank with a height of 12 ft and a radius of 3 ft is drained through a hole in the vertex. If the water level drops at a rate of 1 ft/min, at what rate is water (in ft3/min) draining from the tank when the water depth is 8 ft
Answer:
dhdt≃0.283ft3s
Step-by-step explanation:
dhdt≃0.283ft3s
The draining from the tank when the water depth is 8 ft will be negative 1/π feet per minute.
What is differentiation?The rate of change of a function with respect to the variable is called differentiation. It can be increasing or decreasing.
An inverted conical water tank with a height of 12 ft and a radius of 3 ft is drained through a hole in the vertex. If the water level drops at a rate of 1 ft/min.
[tex]\rm \dfrac{dV}{dt} = -1 \ ft/min[/tex]
The volume of the cone is given as,
V = (1/3) πr²h
The relation between r and h is given as,
r / h = 3 / 12
r = h / 4
Then the volume is written as,
V = (1/3) π (h/4)² × h
V = (π / 48) h³
Differentiate the volume with respect to time. Then we have
(dV)/(dt) = (π/48) x 3h² x (dh / dt)
- 1 = (π/48) x 3(4)² (dh / dt)
- 1/π = dh / dt
The draining from the tank when the water depth is 8 ft will be negative 1/π feet per minute.

What is the slope of the line passing through the points A and B, as shown on the graph below?
A)-3
B) -1/3
C) 1/3
D) 3
Answer:
-1/3
Step-by-step explanation:
We can start by finding the coordinates of 2 points, A and B. A is (-3, 8) and B is (3, 6). Now, we can use [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] to find the slope, and if you plug in those points you get (8 - 6)/(-3 - 3) = 2/(-6) = -1/3.

Use the graph to determine the domain and range. Then state whether the relation is a function.
What is the domain of the function?
Answer:
[-2, 4]
Step-by-step explanation:
The domain of a function is the set of all x-values a relation could possibly take on to have an output. This is represented by in the graph by having the line correspond to the x-value. From the graph shown we can see that x-values from -2 to 4 have a line corresponding to them, and the dots are closed meaning it is inclusive. This would be written as: [-2, 4]

Answer:
18 cm²
Step-by-step explanation:
All sides of a rhombus are the same length (as shown by the markings), so one side is 1/4 of the perimeter:
(24 cm)/4 = 6 cm . . . . side length
As with all parallelograms, the area is the product of the side length and the height perpendicular to that side:
A = (6 cm)(3 cm) = 18 cm²
It has an area of 18 cm².

1.) I'm trying to see if I got this answer right. If not, correct me.
Step-by-step explanation:
The constant of proportionality (or constant of variation), denoted by "k," represents the constant proportion or ratio that exists between two variables, y and x, such that y = kx.
The given problem asks for you to identify the constant of proportionality and what it represents in context of the problem.
In the equation, y = 4.75x:
y = total cost in dollars earned
x = number of bracelets
The constant of proportionality, k = 4.75, represents the increase in total cost earned for every x number of bracelets sold. In other words, the total increases by 4.75 for every bracelet sold.
Thus, since Liv made x = 2 bracelets, then her total cost will equal to $9.50 because:
y = 4.75x
y = 4.75(2)
y = 9.50
Use this information to write an equation and solve the following problem. When you count by ones from any integer, you are counting consecutive integers. Using variables, three consecutive integers are x, x + 1, and x + 2. The sum of three consecutive integers is 48. What are they? Write an equation to represent the situation and solve.

a trader bought a stock of cabbage for 1200 rupees. after removing the spoiled stock, he had a loss of 8%. what is the amount he got by selling the cabbage
An item that originally cost $100 is decreased by 8%. The reduced price is then increased by 8%.
The resulting price is_
between $92 and $100
$92
$100
more than $100
Answer:
$99.36
Step-by-step explanation:
Hii!
So first, you need to find 8% of $100. You can do that by 100 x 0.08 which is $8. This means that the cost is reduced by $8 so 100 - 8 = $92
The reduced price is $92.
Then if we increase the reduced price by 8%, we will find the resulting price. Agani we find 8% of $92 which is 0.08 x 92 = 7.36. This means we have to increase the cost of $92 by this amount. $92 + 7.36 = $99.36
Hope this helps :)
Answer: 99.36
Step-by-step explanation:
because when you add 430 to 0 it makes 492/5 x 40 then x goes into m 4302 times there for its 99.36 USD.

..A teacher is buying T-shirts for her algebra class.
- Long-sleeve T-shirts (x) cost $16 each.
- Short-sleeve T-shirts (y) cost $10 each.
The teacher wants to buy at least 24 T-shirts, and she wants to spend no more than $300 in all. Which system of inequalities represents this situation?
Answer:
[tex]240\leq 10x+16y\leq 300[/tex]
Step-by-step explanation:
Let short-sleeve be x and long-sleeve be y
So, the least amount she could spend buying at least 24 shirts is $240 because the cheapest shirt is $10/shirt. The max amount is already given.
[tex]240\leq 10x+16y\leq 300[/tex]
