Find an equation for the line that passes through the points (-6,6)and (4,6).
Answers
To find the equation of the line, we will use the formula below;
\(y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\)x₁=-6 y₁=6 x₂=4 y₂=6
substitute the values into the formula
\(y\text{ - 6 =}\frac{6-6}{4+6}(x\text{ + 6)}\)\(y-6=\frac{0}{10}(x+6_{})\)
y - 6 = 0

Find the local maximum and local minimum values of f using both the First and Second Derivative Tests. f(x) = 3 + 6x2 - 4x3 = local maximum value x local minimum value x
Answers
To find the local maximum and local minimum values of the function f(x) = 3 + 6\(x^2\) - 4\(x^3\), we can use the First and Second Derivative Tests.
The critical points of the function can be determined by finding where the first derivative is equal to zero or undefined. Then, by analyzing the sign of the second derivative at these critical points, we can classify them as local maximum or local minimum points.
To find the critical points, we first calculate the first derivative of f(x) as f'(x) = 12x - 12\(x^2\). Setting this derivative equal to zero, we solve the equation 12x - 12\(x^2\) = 0. Factoring out 12x, we get 12x(1 - x) = 0. So, the critical points occur at x = 0 and x = 1.
Next, we find the second derivative of f(x) as f''(x) = 12 - 24x. Evaluating the second derivative at the critical points, we have f''(0) = 12 and f''(1) = -12.
By the First Derivative Test, we can determine that at x = 0, the function changes from decreasing to increasing, indicating a local minimum point. Similarly, at x = 1, the function changes from increasing to decreasing, indicating a local maximum point.
Therefore, the local minimum occurs at x = 0, and the local maximum occurs at x = 1 for the function f(x) = 3 + 6\(x^2\) - 4\(x^3\).

A jeweler designs necklaces that are perfectly round open- circles each with a radius of 8.4mm. (1m= 1000mm) What is the largest number of open- circle necklaces that can be made from a wheel of spooled gold that is 42m long?
Answers
Answer:
795
Step-by-step explanation:
First, we find the circumference of 1 ring.
c = 2πr
c = 2 × 3.14159 × 8.4 mm
c = 52.7787 mm
The circumference of 1 ring is the length of spooled gold used for 1 ring.
The spool has a total length of 42 m.
42 m × 1000 mm / 1 m = 42,000 mm
The spool has a total length of 42,000 mm.
Now we divide the length of the spool by the length of 1 ring.
42,000 mm / 52.7787 mm = 795.78
He can make 795 rings.
problem 12a: fullerton iv company has had a policy of reordering inventory every 30 days. using the data below, what is the economic order quantity eoq?ordering cost f $10 per ordercarrying cost c 20% of purchase price purchase price p $10 per unittotal sales per year s 1,000 units safety stock days per year 360. continuing with the previous question, what is the total inventory cost, tic?
Answers
The economic order quantity (EOQ) for Fullerton IV Company is 100 units. The total inventory cost (TIC) is $200.
The economic order quantity (EOQ) for Fullerton IV Company can be calculated using the given information. The EOQ formula is:
EOQ = √((2 * S * F) / C)
where S is the total annual sales, F is the ordering cost per order, and C is the carrying cost as a percentage of the purchase price.
Given data:
Ordering cost (F) = $10 per order
Carrying cost (C) = 20% of purchase price
Purchase price (P) = $10 per unit
Total sales per year (S) = 1,000 units
Substituting these values into the formula, we get:
EOQ = √((2 * 1,000 * 10) / (0.2 * 10))
Simplifying further:
EOQ = √(20,000 / 2)
EOQ = √10,000
EOQ = 100
Therefore, the economic order quantity (EOQ) for Fullerton IV Company is 100 units.
To calculate the total inventory cost (TIC), we need to consider both the ordering cost and the carrying cost. The formula for TIC is:
TIC = (S / EOQ) * F + (EOQ / 2) * C * P
where S is the total annual sales, EOQ is the economic order quantity, F is the ordering cost per order, C is the carrying cost as a percentage of the purchase price, and P is the purchase price per unit.
Substituting the given values into the formula, we have:
TIC = (1,000 / 100) * 10 + (100 / 2) * 0.2 * 10
Simplifying further:
TIC = 10 * 10 + 50 * 0.2 * 10
TIC = 100 + 100
TIC = 200
Therefore, the total inventory cost (TIC) for Fullerton IV Company is $200.

General Sherman, a tree located in Sequoia National Park, stands 275
feet tall. To see the top of the tree, Carlos looks up at a 15° angle of elevation. If Carlos is 6 feet tall, how far is he from the base of the tree to the nearest foot? There are 4 options A.1004 B.1020 C.1026 D.1049
Answers
Answer:
Step-by-step explanation:
If Carlos is 6ft tall and looks up at the tree that is 275 ft tall, subtract those two.
275 - 6 = 269
Use tangent with the given angle and the new height. The distance is x.
tan15 = 269/x
x = 269/tan15
x = 1004ft
The distance from Carlos to the tree, given he is 6 feet tall and looks up at a 15° angle of elevation to see the top of a 275-foot tall tree located in Sequoia National Park, is 1026.
Hence option C is correct.
According to the information given,
We can set up a right triangle with Carlos's eye level, the top of the tree, And the base of the tree as the three points of the triangle.
Carlos's height of 6 feet can be used as one side of the triangle,
And we can use the tangent function to find the length of the adjacent side.
A tangent of 15 degrees is equal to the opposite side (height of the tree) divided by the adjacent side (distance from Carlos to the tree).
So, we can solve for the adjacent side by multiplying the height of the tree by the tangent of 15 degrees:
tan(15) = height of the tree / distance from Carlos to the tree
Distance from Carlos to the tree = height of the tree / tan(15)
Plugging in the values given:
Distance from Carlos to the tree = 275 / tan(15)
≈ 1026
Therefore,
The nearest foot to the distance from Carlos to the tree is option C. 1026.

x = 5 - y → (2)
substitute x = 5 - y into (1)
4(5 - y) - y = 5
20 - 4y - y = 5
20 - 5y = 5 ( subtract 20 from both sides )
- 5y = - 15 ( divide both sides by - 5 )
y = 3
substitute y = 3 into (2)
x = 5 - y = 5 - 3 = 2

x = 10/5 = 2
x + y = 5
2 + y = 5

over a 24-hour period, brown bears counted 940 salmon swimming upstream, and they safely assumed that they only counted 20% of the total number of fish going by. the salmon-spawning haven along copper river measures approximately 70,000 cubic meters of water. given that the haven was empty before this week, that the salmon swim upstream at a constant rate, and that once they reach the haven, the salmon hang out there indefinitely, what will the population density of salmon in the copper river spawning haven be after one week (to the nearest thousandth fish per cubic meter)?
Answers
The population density of salmon in the Copper River spawning haven after one week is approximately 0.218 fish/m3.
We can calculate the population density of salmon in the spawning haven by dividing the total number of salmon by the volume of the haven:
Population density = total number of salmon / volume of haven
Population density = 19,600 / 90,000
Population density = 0.2178 fish/m3
Rounding to the nearest thousandth of fish/m3 gives us a population density of 0.218 fish/m3.
Density is a physical property of matter that measures the amount of mass per unit volume of a substance. Density is an important concept in the physical sciences and is a fundamental property of matter that can provide valuable information about the nature of a substance.
The density of an object can provide information about its composition and physical properties. For example, materials with a higher density are generally more compact and have a greater mass per unit volume than materials with a lower density. This property is important in many scientific fields, including physics, chemistry, and engineering. Density can also be used to determine if an object will float or sink in a fluid.

Relative to ground level, what is the elevation of the hole after placing the plant in the hole?
Enter your answer as a mixed number in the simplest form by filling in the boxes.
Answers
Given that Jackson digs a hole at a rate of 3/5 feet every 10 minutes, and he dug for 40 minutes. Thus, the total depth of the hole dug by him is given by:
3/5 x 4 = 12/5
= 2.4 feet (Depth of the hole dug by Jackson)
After he placed the plant in the hole, the depth of the plant is 9/10 feet.
So, the total depth of the hole that is filled after he placed the plant is:
2.4 + 9/10= 12/5 + 9/10
= 24/10 + 9/10
= 33/10 feet
Now, if we consider ground level as zero, then the elevation of the hole is 33/10 feet above the ground level.
Therefore, the relative elevation of the hole after placing the plant in the hole is 33/10 feet above ground level.
Jackson digs a hole at a rate of 3/5 feet every 10 minutes. After digging for 40 minutes, Jackson places a plant in the hole that fills exactly 9/10 feet of the hole.

What are expressions?
Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be of addition, subtraction, multiplication, or division. For example, x + y is an expression, where x and y are terms having an addition operator in between. In math, there are two types of expressions, numerical expressions - that contain only numbers; and algebraic expressions- that contain both numbers and variables.
e.g. A number is 6 more than half the other number, and the other number is x. This statement is written as x/2 + 6 in a mathematical expression. Mathematical expressions are used to solve complicated puzzles.

The interior angles sum = 180° ( n - 2 )
~~~~~~~~
n = 7
180° ( 7 - 2 ) = 900°
Answer:
900 degrees
Step-by-step explanation:
just apply the formulas discussed in class !
The sum of interior angles in a triangle is 180°. To find the sum of interior angles of a polygon, multiply the number of triangles in the polygon by 180°.
The number of triangles in each polygon is two less than the number of sides.
The formula for calculating the sum of interior angles is:
(n−2)×180∘ (where n is the number of sides)
in our case we have 7 sides.
so, we could split this polygon into 5 triangles.
each of these triangles would have an angle sum of 180°.
so, the angle sum of the polygon is
5×180 = 900°

The given polynomial function f meets the criteria of being negative for all real numbers and having an increasing slope when x is less than -1 and between 0 and 1. Therefore, we can represent this graphically on the coordinate plane by starting at the origin (x=0, y=0). We can then plot a line going from the origin with a negative slope (moving left to right). This will represent the increasing slope of the graph when x<-1 and 0<x<1.
We can then plot a line going from the origin with a positive slope (moving left to right). This will represent the decreasing slope of the graph when -1<x<0 and x>1.
The final graph should resemble a "V" shape starting from the origin and extending to the right (with two lines converging at the origin). The graph should be entirely below the x-axis, since the given polynomial function is negative for all real numbers.

determine the area of the given region under the curve. y = 1/x6
Answers
The area of the region under the curve y = 1/x^6 between x = 1 and x = ∞ is 1/5 square units.
The region under the curve y = 1/x^6 is bounded by the x-axis and the vertical line x = 1. To find the area of this region, we need to evaluate the definite integral ∫[1,∞] 1/x^6 dx.
We can do this using the power rule of integration:
∫[1,∞] 1/x^6 dx = [-1/5x^5] [1,∞] = [-1/(5∞^5)] - [-1/(5(1)^5)] = 1/5
Therefore, the area of the region under the curve y = 1/x^6 between x = 1 and x = ∞ is 1/5 square units.

the diameter of a cone is 1.5 meters, the height is 1.5 times the radius, what is the volume?
Answers
Answer:
.66 cu. meters
Step-by-step explanation:
volume for cone is V=1/3 x TT x r^2 x height
TT (pi) is 3.14
radius is 1/2 of diameter (1/2 x 1.5 = .75 )
height is 1.5 x radius (1.5 x .75 = 1.125)
V= 1/3 x 3.14 x .75^2 x 1.125
V= .66 cu. meters

85. What is the value of x?والے1040)DDrawing not to scaleA 38°B. 128°C. 76D. 52°
Answers
Given:
One of the angle of a triangle is 104°.
The objective is to find the missing angle x.
If two sides of a triangle are equal, then it is an isosceles triangle.
In an isosceles triangle, the angle formed by the equal sides is also equal.
Then, the value of angle x can be calculated angle sum property of triangle.
\(\begin{gathered} x+x+104\degree=180\degree \\ 2x+104\degree=180\degree \\ 2x=180\degree-104\degree \\ 2x=76\degree \\ x=\frac{76}{2} \\ x=38\degree \end{gathered}\)Hence, option (A) is the correct answer.
what is the sum of the perimeter in units of the five squares in the design
Answers
Answer:
Assuming that the squares are the same size,
the sum of the perimeter of the five squares =
(20 units × side length of each square in units)
If the squares are different sizes, the sum of the perimeter of the five squares =
(4 units × side length of square 1 in units) + (4 units × side length of square 2 in units) + (4 units × side length of square 3 in units) + (4 units × side length of square 4 units) + (4 units × side length of square 5 in units)
Explanation:
The perimeter of a square is 4 × side length because a square has 4 sides and the perimeter of a figure is the surrounding length of the figure.
