The water pressure on a submerged object is given by P = 64d, where P is the pressure in pounds per square foot, and d is the depth of the object in feet. a. solve the formula for d. b. Find the depth of a submerged object if the pressure is 672 pounds per square foot.
The water pressure on a submerged object is given by P = 64d, then the
a. The answer to the subject of the formula, "d," is d = P/64.
b. The depth of a submerged object if the pressure is 672 pounds per square foot is 10. 5 feet
A function can be defined as an expression, law or rule that shows the relationship between two variables.
These variables are namely;
Independent variableDependent variableGiven the role as;
P = 64d
Where;
P stands for pounds per square foot of pressure.
d represents the object's depth in feet.
Let's now make the variable "d" the focus of the formula.
The coefficient of the variable "d," which is 64, is used to divide both sides of the equation. So that the variable can stand on its own, this is done.
(a) We get,
P/64 = 64d/64
d = P/ 64
(b) P equals 672 pounds per square foot if there is pressure.
When the variable's value is substituted into the formula, we get;
d = P/64
Then,
d = 672/64
Discover the quotient,
d = 10. 5 ft.
The value is 10.5 feet .
Therefore,
a. The answer to the subject of the formula, "d," is d = P/64.
b. The depth of a submerged object if the pressure is 672 pounds per square foot is 10. 5 feet.

Isaac wants to play miniature golf. Go Golf charges $2.50 for ball and club rental and $4.25 per game. Golf Games charges $3.25 for ball and club rental and $8.50 for two games. For how many games would the cost be the same? Write and solve an equation to determine the number of games for which the cost would be the same.
For 47 Go golf and 54 golf game would the cost be the same.
Given that -
Go Golf charges -
Ball and club rental = $2.50
For 1 game = $4.25 and
Golf Games charges -

Total charges of Go golf per game = $2.50 + $4.25 = $6.75
Total charges of Golf game for 2 games = $3.25 + $8.50 = $11.75
For per game = $11.75 / 2 = $5.875
For Go golf let game = x and
for golf game let game = y
6.75 x = 5.875y

Construct a polynomial function with the stated properties. Reduce all fractions to lowest terms.
Third-degree, with zeros of -2,-1, and 5, and a y-intercept of -10.
Answer:
y = x³ -2x² -13x -10
Step-by-step explanation:
You want a polynomial with x-intercepts -2, -1, and 5, and a y-intercept of -10.
Polynomial factorsA polynomial with zero x = p will have a factor of (x -p). The three given zeros mean factors of the desired polynomial will be ...
p(x) = (x -(-2))(x -(-1))(x -5) = (x +2)(x +1)(x -5)
Expanding this gives ...
p(x) = (x +2)(x² -4x -5) = x³ -2x² -13x -10
This polynomial has a constant of -10, which will be its y-intercept. No additional scaling is needed.
The polynomial function is ...
y = x³ -2x² -13x -10
Which of the following is the graph of (g-f)(x)?
The graph (g-f)(x)=-4x complies with the query.
Graph example: What is it?An edge denotes the connection between the x and y vertices and is represented by the pair (x ,y). In the examples that follow, circles stand in for vertices and lines for edges.
The graph indicates that line generated by function f(x) passes through the points (1,-3) and (0,0) and that line similarly passes through the points (1,1) and (0,0).
With the use of the formula Y-Y1 = y2-y1/x2-x1, we can thus determine the equation of the lines (x-x2)
Therefore, the equation of the line produced by the function f(x) y+3= 3-0/0-1 (x-1)
Function f(x) Equals 3x since y+3=-3x+3 y=-3x.
the line drawn by the function g(x) has the equation y=x, hence function g(x)=x.
We now need to figure out, (g-f) (x) = g(x)- f(x) = -3x-x = -4x

What is an inequality?
An inequality in mathematics is a relationship that makes a non-equal comparison between two integers or other mathematical expressions. It is most commonly used to compare the sizes of two numbers on a number line. There are multiple notations used to denote various types of inequalities: (i)The symbol a b indicates that an is less than b. (ii)A > b indicates that an is greater than b. In either scenario, a and b are not equal. These are characterized as stringent inequalities because an is either strictly less than or strictly bigger than b. Equivalence is not allowed. In contrast to rigorous inequalities, there are two forms of non-strict inequality relations.

Suppose that y varies directly with x and that y=77 when x=7. What is the value of x when y=55? Responses 50 50 11 11 24 24 5
As y varies directly with x, the numerical value of x when y = 55 is 5.
How to solve direct variation problem?Proportional relationships are relationships between two variables where their ratios are equivalent.
A direct variation equation is a linear equation in two variables.
It is expressed as;
y ∝ x
Hence,
y = k(x)
Where k is proportionality constant.
Given that;
y = 77x = 7Proportionality constant k = ?First, we determine the proportionality constant of the direct variation.
y = k(x)
77 = k(7)
Divide both sides by 7
77/7 = k(7)/7
k = 77/7
k = 11
Now, we find the value of x when y = 55
y = k(x)
55 = 11(x)
Divide both sides by 11
55/11 = 11(x)/11
x = 55/11
x = 5
Therefore, the numerical value of x is 5.

Step-by-step explanation:
a city planner wants to build a road perpendicular to D street. What is the slope of the new road?
The slope of the new road is zero.
How to find slope?The slope of a line is the change in y with respect to the change in x.
In other words, the slope of a line is rise over run.
Therefore, the new road the city planner wants to build is perpendicular to the the D street.
(5, 1)(5, 4)
slope of D street = 4 - 1 / 5 - 5
slope of D street = 3 / 0
slope of D street = infinity
An infinite slope is simply a vertical line. Therefore, it is only perpendicular to a horizontal line which will have a slope of 0. Hence, the new road should have a slope of 0.

It should be emphasized that a relationship is proportional if its graph is a line that passes through its origin.
How should the information be illustrated?
If the graph of a connection is a line passing through the origin, the connection is proportionate. If it is not a line or ray that fails to do this, the ratio is not proportional. The equation for the proportionality constant is K = y/x. This is the same equation used to get the slope of a straight line with respect to the origin.
If the graph of a relationship is a line or ray that goes through the origin, the relationship is proportional. If the line or ray does not pass through the origin, it is not proportional. Additionally, if anything is not linear, it is not proportionate.

4408 books must to be produced so that production costs is equal to sales money.
What is production cost?
Production costs refers to the direct and indirect costs that come from manufacturing a product. Production costs usually include expenses, such as labor, raw materials and manufacturing supplies. Cost of products sold are the production costs incurred on goods that is actually sold in a certain specified period
Let the no. of books= X
Cost = 9.25X + 49590
revenue = 20.50X
20.50X = 9.25X+ 49590
20.50X - 9.25X = 49590
11.25X = 49590
X = 4408
4408 books must to be produced so that production costs is equal to sales money
We can Check by:
cost = 9.25(4408) + 49590
= 40774+ 49590
