Answers
The dimensions of cone B is radius, 6.8 units and height 7 units.
What are the possible dimensions of cone B?
The possible dimensions of cone B is calculated as follows;
Volume of cone = ¹/₃πr²h
Volume of cone A = ¹/₃π(6²)(4) = 150.8 units³
Volume of cone B = 487 units³ - 150.8 units³ = 336.2 units³

describe how to use the zero product property when solving a quadractic equation by factoring
Answers
X + 1 = 0, so x = -1, and x - 24 = 0, so x = 24. Consequently, the two answers to the equation are x = -1 and x = 24.
What is equation?It is a method for illustrating a notion, a connection, or a behaviour that often involves two or more variables. Equations can be used to explain several events, including economic models and physical principles. They can also be applied to problem-solving and forecasting. Symbols, integers, and mathematical operations like addition, subtraction, multiplication, and division are used to create equations.
An essential tool for factoring quadratic equations is the Zero Factor Property. Finding two terms, one of which is a factor of the constant term and the other of which is a factor of the coefficient of the squared term, whose product is equal to the constant term, is the fundamental principle behind the Zero Factor Property. With this knowledge, the given quadratic equation can be factored into two parts that equal zero.
One must first factor a quadratic equation into two factors that are equal to zero in order to solve it using the zero factor property. To do this, one needs determine the constant term's factors as well as the coefficient of the squared term's factors. The coefficient of the squared term is always obtained by multiplying the factors, which are always different integers.
The constant term's factors are always sums of numbers that result in the constant term. Once the elements are known, the equation can be factored into two factors that are equal to zero each.
Consider the equation [tex]x^2+5x-24=0[/tex], for instance. The factors of the constant term are -1 and 24, while the factors of the squared term's coefficient are 1 and 5. The equation then reads as (x + 1)(x - 24) = 0.
At this stage, the Zero Factor Property can be used to find x. Since all factors must be equal to zero, x can be solved for by setting all factors to zero. Thus, x + 1 = 0, resulting in x = -1, and x – 24 = 0, resulting in x = 24. Thus, x = -1 and x = 24 are the two answers to the problem.

Line F has a slope of −6/3, and line G has a slope of −8/4. What can be determined about distinct lines F and G?
The lines will intersect.
Nothing can be determined about the lines from this information.
The lines are parallel.
The lines have proportional slopes.
Answers
Reasoning:
If we simply the slopes of both lines, line F has a slope of -2 since -6/3=-2, and line G also has a slope of -2 since -8/4=-2. Because the slopes are equal, the lines rise and run at the sane rate, and as long as they have different y-intercepts, they will be parallel. Essentially, both lines will have the same “steepness” but start at different points, so they never intersect.

A squirrel on the ground sees a hole in a tree that could be its new home. The squirrel is 8 feet away
from the base of the tree and sees the hole at an angle of elevation of 43°. How high up the tree is the
hole? Round your answer to the nearest hundredth foot.
Answers
tan(43°) = h/8
Multiplying both sides by 8, we get:
h = 8 * tan(43°)
Using a calculator, we get:
h ≈ 7.19 feet
Therefore, the hole in the tree is approximately 7.19 feet high. Rounded to the nearest hundredth foot, the answer is 7.19 feet.
Let h be the height of the hole above the ground. Then, we have:
tan(43°) = h/8
Solving for h, we get:
h = 8 tan(43°)
h ≈ 7.07 feet
Therefore, the hole is approximately 7.07 feet above the ground.

Complete parts (a) through (g). Use a graphing utility to determine the distance that the ball has traveled when the height of the ball is 80 feet. Choose the correct answer below and, if necessary, fill in the answer box to complete your choice.
Answers
The distance that the ball has traveled when the height of the ball is 80 feet is either about 9.86 feet or about 3.64 feet.
We are given that;
Velocity= 140feet
Inclination= 45degrees
Function h(x)=(-32x^2/140^2)+x
Now,
To find the distance that the ball has traveled when the height of the ball is 80 feet, we need to solve the equation:
h(x) = 80
Substituting h(x) with the given function, we get:
(-32x2/1402) + x = 80
Multiplying both sides by 140^2 and simplifying, we get:
-32x^2 + 140x - 11200 = 0
Dividing both sides by -32 and simplifying, we get:
x^2 - (35/4)x + 350 = 0
Using the quadratic formula, we get:
x = [ (35/4) ± √( (35/4)^2 - 4(350) ) ] / 2 x ≈ 9.86 or x ≈ 3.64
Using a graphing utility, we can confirm that these are the approximate x-intercepts of the function h(x) - 80.

The equation of the tangent line to the graph of y = g(x) at x = 2 is y = 6x - 17.
How to find the equation of the tangent lineThe point-slope form of the equation of a line can be used to find the equation of the tangent line to the graph of y = g(x) at x = 2.
y - y1 = m(x - x1)
where m is the tangent line's slope and (x1, y1) is the point on the g(x) graph at x = 2.
Given that g(2) = -5, the point on the g(x) graph at x = 2 is (2, -5).
We are told that g'(2) = 6, which is the slope of the tangent line at x = 2.
As a result, the tangent line equation is: y - (-5) = 6(x - 2)

Simplify expression sec×sin(-×)+tan(-x) over 1+sec(-×)
Answers
Answer:
-tan(x)/sin^2(x).
Step-by-step explanation:
To simplify the expression:
sec(x)sin(-x) + tan(-x)
1 + sec(-x)
We can use the fact that sin(-x) = -sin(x), cos(-x) = cos(x), and tan(-x) = -tan(x) to rewrite the expression as:
-sec(x)sin(x) - tan(x)
1 + sec(x)
Next, we can multiply both the numerator and denominator by the conjugate of the denominator, 1 - sec(x), to eliminate the square root in the denominator. This gives:
(-sec(x)sin(x) - tan(x))(1 - sec(x))
(1 + sec(x))(1 - sec(x))
Simplifying the numerator by distributing and combining like terms, we get:
-sec(x)sin(x) + sec(x)tan(x) + tan(x) - sec(x)tan(x)
1 - sec^2(x)
Simplifying further by canceling out the sec(x)tan(x) terms in the numerator, we get:
-tan(x)
1 - sec^2(x)
Finally, we can use the identity 1 - sec^2(x) = sin^2(x) to rewrite the denominator and simplify further:
-tan(x)
sin^2(x)
Therefore, the simplified expression is -tan(x)/sin^2(x).

The total number of zero pairs in the expression (-5) + (-8) is 2.
How to find the number of zero pairs?We must pair the negative numbers so that their sum is equal to zero in order to determine the number of zero pairs in this expression. To put it another way, we need to find pairs of numbers whose sum is the same as their additive inverse.
We are combining two negative numbers in the expression (-5) + (-8).
In this case, we can pair the (-5) with a (+5), since (-5) + (+5) = 0, and we can also pair the (-8) with a (+8), since (-8) + (+8) = 0.

If the spinner does not land on yellow, what is the probability it will land on blue?
Answers
Answer: 2/4 or 1/2
Step-by-step explanation: Based on the spinner shown, there are 5 equal sections, 1 of which is yellow and 2 of which are blue. If the spinner does not land on yellow, it will land on one of the 4 other sections, 2 of which are blue.
Therefore, the probability of landing on blue given that it does not land on yellow is 2/4 or 1/2.
En un cuadrado de 10 cm por 10 cm pinta de
forma creativa el 30 % de su área y encuentra
la fracción correspondiente.
Answers
10 cm x 10 cm = 100 cm²
Para encontrar el 30% del área del cuadrado, multiplicamos el área por 0.3:
100 cm² x 0.3 = 30 cm²
Por lo tanto, el área que se debe pintar de forma creativa es de 30 cm².
La fracción correspondiente se obtiene dividiendo el área que se debe pintar por el área total del cuadrado:
30 cm² / 100 cm² = 3/10
Por lo tanto, la fracción correspondiente es 3/10.

A machine that cost $500,000 has an estimated residual value of $20,000 and an estimated useful life of 20,000 machine hours. The company uses units-of-production depreciation and ran the machine 2,000 hours in year 1, 4,000 hours in year 2, and 8,000 hours in year 3.
Calculate its book value at the end of year 3. (Do not round intermediate calculations.)
Answers
The machine's book value at the end of year three is $164,000.
How to calculate the depreciation rate per machine hour?The total amount of hours used by the machine in the first three years is: 2,000 + 4,000 + 8,000 = 14,000 hours
To calculate the annual depreciation expense, we must first establish the depreciation rate per machine hour. The following is how the depreciation rate per machine hour is calculated:
Depreciation rate per machine hour = (machine cost - estimated residual value) / total number of machine hours estimated
Rate of depreciation per machine hour = ($500,000 - $20,000) / 20,000 machine hours
Depreciation per machine hour = $480,000 divided by 20,000 machine hours
Rate of depreciation per machine hour = $24 per machine hour
We may compute the depreciation expense for each year by using the depreciation rate per machine hour:
Depreciation expense in year one = depreciation rate per machine hour x hours used in the first year
Depreciation expense in year one = $24 x 2,000 hours
Depreciation expense for the first year = $48,000
Year 2 depreciation expense = Depreciation rate per machine hour multiplied by the number of hours consumed in year 2.
Depreciation expense for year 2 = $24 x 4,000 hours
Depreciation expense for year two = $96,000
Depreciation expense in year three = depreciation rate per machine hour x hours used in year three
Depreciation expense in year three = $24 x 8,000 hours
Depreciation expense during the third year = $192,000
The accumulated depreciation for the first three years is the sum of the following depreciation expenses:
Accumulated depreciation equals the sum of year one depreciation expense, year two depreciation expense, and year three depreciation expense.
Depreciation accumulated = $48,000 + $96,000 + $192,000
Depreciation accumulated = $336,000
To compute the machine's book value at the end of the year 3. We deduct the accumulated depreciation from the machine's cost:
Machine book value = machine cost minus accumulated depreciation
The machine's book value is $500,000 minus $336,000
The machine's book value is $164,000
As a result, the machine's book value at the end of year three is $164,000.
