The point-slope form with a slope of 5/2 and a point of (4,-7) is 5x-2y=34.
What is line equation?
In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical phrase with two equal sides separated by an equal sign is called an equation. An example of an equation is 4 + 6 = 10. Linear equations are classified into three types: point-slope, standard, and slope-intercept.
Here,
The slope of line perpendicular to the line y +6=-2/5(x-1)
m1=5/2
point=(4,-7)
y-y1=m(x-x1)
y+7=5/2(x-4)
2y+14=5x-20
5x-2y=34
The point-slope form for slope given as 5/2 and point as (4,-7) will be 5x-2y=34.

The volume of the crater is 64800000 m³
Calculating volume of the craterFrom the question, we are to determine the volume of the crater.
From the given information,
d = 2∛(V/0.3)
To determine the volume,
First, we will solve for V in the equation
d = 2∛(V/0.3)
Divide both sides by 2
d/2 = ∛(V/0.3)
Take the cube of both sides
(d/2)³ = V/0.3
Then,
V = 0.3(d/2)³
Now, substitute the value of the diameter
d = 1200m
Then,
V = 0.3(1200/2)³
V = 0.3(600)³
V = 64800000 m³
Hence, the volume is 64800000 m³

A shipping container will be used to
transport several 150-kilogram crates
across the country by rail. The greatest
weight that can be loaded into the
container is 27500 kilograms. Other
shipments weighing 6800 kilograms have
already been loaded into the container.
Write and solve an inequality which can
be used to determine x, the number of
150-kilogram crates that can be loaded
into the shipping container.
Answer:
x=138
Step-by-step explanation:
The question is a high school Mathematics problem. It involves using inequalities to solve a practical problem about a shipping container's weight limit. The answer found was that a maximum of 138 crates can be added to the container.
Explanation:In this Mathematics problem, we have a shipping container that can hold a maximum weight of 27500 kilograms and there are already shipments totaling 6800 kilograms inside. We want to find out how many 150-kilogram crates (let's call this number 'x') can be added to the container without exceeding the maximum allowable weight.
Firstly, we build an inequality. The total weight of the container should not exceed 27500 kilograms, so we have:
6800 (the weight of the already loaded shipments) + 150*x (the weight of the x crates) ≤ 27500
This simplifies to:
150*x ≤ 20700 (because 27500-6800=20700)
Finally, to solve the inequality for 'x', divide throughout by 150:
x ≤ 138 (because 20700/150=138)
So, 138 is the maximum number of 150-kilogram crates that can be loaded into the shipping container without violating the weight constraint.

A cubic polynomial function f is defined by. 3. 2. ( ) 4. f x x ax bx k where a, b, and k are constants
In a cubic polynomial function f is defined by f(x) = 4x³ + ax² + bx + k, where a, b, k, are constants and has a local minimum at x = -2 and a local maximum at x = 0, then values of a and b is 12 and 0 respectively. If integrate of f(x)dx = 32 from 0 to 1, then value of k is 27.
The given cubic polynomial function is
f(x) = 4x³ + ax² + bx + k
f'(x) = 12x² + 2ax + b
f''(x) = 24x + 2a
At local maximum f' = 0
f'(0) = 12×(0)² + 2a×(0) + b = 0
b = 0
At local minimum, f' = 0
That is f'(-2) = 0 and f''(-2) > 0
f'(-2) = 12×(-2)² + 2a×(-2) + b = 0
48 - 4a + b = 0
4a - b = 48
a = 12
Therefore, f(x) = 4x³ + 12x² + k
Integrate f(x)dx = 32 from 0 to 1, that is
∫₀¹ f(x)dx = 32
∫₀¹ (4x³ + 12x² + k) dx = 32
[ x⁴ + 4x³ + kx ]₀¹ = 32
(1⁴ - 0⁴) + 4(1³ - 0³) + k(1 - 0) = 32
1 + 4 + k = 32
k = 27

-10.5 + m/ 11.57 = -2.748
Solve for M
Answer: 89.69
Step-by-step explanation:
-10.5 + m/ 11.57 = -2.748

m/ 11.57 = 7.752
Then we multiply both sides by 11.57
m = 89.69064, or we can simplify it be 89.69

If Dave bought 5 packs of snacks, then the amount on Dave's account for snack last month should be $3.75.
Dave purchased 5 packs of snacks last month and the cost of each pack was $0.75. The total cost of the snacks was charged to Dave's account, so his account balance should reflect the total cost of the snacks. In this case, Dave purchased 5 packs of snacks, so the total cost would be $3.75 ($0.75 x 5). Therefore, Dave's account balance should show $3.75 for the snack purchases last month. This amount is the sum of the individual cost of each snack pack, multiplied by the number of packs Dave purchased. In this case, the amount on Dave's account for snack last month should be $3.75.

The month they would have the same amount of money is 2 months.
When would they have the same amount of money?The linear equation that can be used to represent the total amount of money saved by each person is
Total amount saved = amount started with + (amount deposited per month x number of months)
Amount saved by Tonya = $60 + $20m
Amount saved by Jull = $20 + $40m
When they save the same amount of money, the two two above equations would be equal:
60 + 20m = 20 + 40m
In order to determine the value of m, take the following steps:
60 - 20 = 40m - 20m

m = 40 / 20

The average rate of change of a function is said to be a measure of how much the function changed per unit, on average, over that interval. It is also said to be derived from the slope of the straight line connecting the interval's endpoints on the function's graph
f(x) over an interval [x1,x2] is given by:
average rate of change = change in y/change in x
= f(x2) − f(x1) / x2−x1

the extent to which a reesearcher's sample is representative of the population that it was drawn from is called
The extent to which the researcher can refer that findings with a sample from which it was drawn is referred to as generalizability.
Generalizability refers to the ability to extrapolate study findings from a sample to the entire population. It also refers to the capacity to apply findings from one study to a similar environment in a different investigation.
Generalizability and transferability are two research traits that are related. When considering generalizability in research, there are two features or dimensions to consider: generalizability as it relates to the specific population on which the research is conducted, and generalizability on a global scale.
Such studies will be easier to generalize if the researcher uses adequate sampling approaches, sample sizes, and exact processes.
In general, a study has strong generalizability when the findings apply to a wide range of persons or situations. The study has weak generalizability if the results can only be applied to a subset of the population or in a very specific circumstance.

In this question we have been given Clayton and Iris purchase admission to a carnival plus a number of game tickets. Clayton purchased 10 game tickets and spend $19. 50.
Iris purchase 15 game tickets and spend $23. 25
We need to determine cost per game ticket.
The total cost of Clayton's game tickets is $19.50 for 10 tickets,
So, by unitary method the cost per ticket is:
= 19.5/10
= $1.95 per ticket.
The total cost of Iri's game tickets is $23.25 for 15 tickets
So, by unitary method the cost per ticket is:
= 23.25/15
= $1.55 per ticket.
The combined cost of all the game tickets is $19.50 + $23.25 = $42.75.
The total number of game tickets purchased is 10 tickets + 15 tickets = 25 tickets.
