Suppose you are climbing a hill whose shape is given by the equation z = 1400 − 0.005x2 − 0.01y2, where x, y, and z are measured in meters, and you are standing at a point with coordinates (100, 120, 1206). the positive x-axis points east and the positive y-axis points north. (a) if you walk due south, will you start to ascend or descend?

Answers

Answer 1
Answer: You start to ascend

Explanation:

Since you are walking due south and the positive y-axis points north, the y-coordinate decreases.

Let 

[tex]y'[/tex] = y-coordinate after walking due south
[tex]z'[/tex] = z-coordinate (or the height) after walking due south

So, the point where you stand after walking due south has a coordinate of [tex](100, y', z')[/tex]. Moreover,

[tex]z' = 1,400 - 0.05(100)^2 - 0.01(y')^2 \\ \boxed{z' = 1350 - 0.01(y')^2}[/tex]

Since the y-coordinate decreases after walking due south and [tex]z' = 1350 - 0.01(y')^2[/tex],

[tex] y' \leq 120\\ \Rightarrow (y')^2 \leq 120^2 = 14,400\\ \Rightarrow -0.01(y')^2 \geq -0.01(14,400) = -144\\ \Rightarrow z' = 1,350 - 0.01(y')^2 \geq 1,350 - 0.01(14,400) = 1,206\\ \Rightarrow \boxed{z' \geq 1,206}[/tex]

So, the height after walking due south exceeds 1,206 meters, which is the previous height before walking due south. Therefore, if you walk due south from point with coordinates (100, 120, 1206), you are ascending.
Answer 2

If walking due south from the point (100, 120, 1206) will cause you to descend, as the slope of the hill in the southward direction is negative.

To determine whether you will ascend or descend when walking due south from the point (100, 120, 1206), we need to consider the slope of the hill in the southward direction, which corresponds to the negative y-direction.

Given the equation of the hill's shape: [tex]\[ z = 1400 - 0.005x^2 - 0.01y^2 \][/tex]

We can find the slope in the y-direction (southward) by taking the partial derivative of z with respect to y:

[tex]\[ \frac{\partial z}{\partial y} = -2 \cdot 0.01 \cdot y \][/tex]

Evaluating this derivative at the point (100, 120, 1206) gives us the slope in the y-direction at that point:

[tex]\[ \frac{\partial z}{\partial y}\Bigg|_{(100, 120, 1206)} = -2 \cdot 0.01 \cdot 120 = -2.4 \][/tex]

Since the slope is negative, this means that as you move in the positive y-direction (northward), the height z decreases. Conversely, moving in the negative y-direction (southward) will also result in a decrease in height z, because the slope is linear and does not change direction.

Therefore, walking due south from the point (100, 120, 1206) will cause you to descend, as the slope of the hill in the southward direction is negative.

Find the fuction h (x) =f(x) - g (x) if f (x)=3^x and g (x)= 3^2x - 3^x

Answers

if h(x) = f(x) - g(x)

then --> h(x) = 3^x - 3^2x - 3^x
             h(x) = -3^2x
         


To find h(x) = f(x) - g(x), we substitute and simplify the given functions. The result is h(x) = 2 × 3ˣ - 3²ˣ. This solution involves basic algebraic manipulation and exponent rules.

Let's start by defining the given functions:

f(x) = 3ˣg(x) = 3²ˣ - 3ˣ

We need to find h(x) = f(x) - g(x). Substitute the expressions for f(x) and g(x):

h(x) = 3ˣ - (3²ˣ  - 3ˣ)

Now simplify the expression inside the parentheses:

h(x) = 3ˣ - 3²ˣ  + 3ˣ

Combine like terms:

h(x) = 3ˣ+ 3ˣ - 3²ˣh(x) = 2 × 3ˣ - 3²ˣ

Thus, the function h(x) = 2 × 3ˣ - 3²ˣ is found by subtracting g(x) from f(x).

What is the solution set to the inequality-3x 5.92-15.4 for x in the set (-10,-5, 0, 5, 10)?

Answers

I have attached an image of the question

Answer:

-10 , -5 , 0 and 5

Explanation:
The given inequality is:
-3x + 5.9 ≥ -15.4

We will need to isolate the x on one side of the inequality as follows:
First, we will subtract 5.9 from both sides of the inequality as follows:
-3x + 5.9 - 5.9 ≥ -15.4 - 5.9
-3x ≥ -21.3

Then, we will divide both sides of the inequality by -3. Remember that when we divide by a negative number, we flip the inequality sign as follows:
-3x / -3 ≥ -21.3 / -3
x ≤ 7.4

This means that x could be any value starting from -∞ till 7.4
The given set is (-10,-5, 0, 5, 10)
Now, we will check the given options, the correct ones would be those having a value of 7.4 or less.
This means that the correct options are:
-10 , -5 , 0 and 5

Hope this helps :)

Final answer:

The solution set to the given inequality '-3x < 5.92 - 15.4' is {5, 10}.

Explanation:

The student's question seems to be about solving an inequality to find which values from a given set satisfy it. While the inequality itself appears to be incorrectly written or has a typo, I'll assume it's meant to be '-3x < 5.92 - 15.4'.

We can begin by simplifying the right side of the inequality:

5.92 - 15.4 = -9.48

So the inequality becomes:

-3x < -9.48

To solve for x, we divide both sides by -3, remembering to reverse the inequality sign because we are dividing by a negative number:

x > 9.48 / 3

x > 3.16

Now we can compare this result to the set of numbers given: (-10, -5, 0, 5, 10).

The only numbers greater than 3.16 are 5 and 10.

Therefore, the solution set to the inequality is {5, 10}.

Philip is going on a 400040004000-kilometer road trip with three friends. The car consumes 666 liters of gas per 100100100 kilometers, and gas costs \$1.50$1.50dollar sign, 1, point, 50 per liter.

Answers

 If Philip and his friends want to split the cost of gas evenly, how much should they each pay?
the amount of gas it consumes per 100 km = 6 l
the cost per litre = $1.50
the total distance of the trip = 4000 km
If 100 km consumes - 6 l
Then 1 km consumes - 6/100 l/km
therefore amount of gas for the whole trip of 4000 km = 6/100 l/km * 4000 km
the gas consumed = 240 l
cost of 1 l = $1.5
then the cost of gas for the whole ride = 240 l * $ 1.5
  cost = $ 360
there are 4 friends , cost of each friend = $ 360/4 = $ 90
cost each friend has to pay = $ 90

Use Cavalieri’s Principle to calculate the exact volume of an oblique cylinder with a height of 10 meters and a circular base with a radius of 8 meters

Answers

I think it is 640 pi

Answer: Volume of an oblique cylinder is 2011.43 sq.m.

Step-by-step explanation:

Since we have given that

Radius of a cylinder = 8 meters

Height of a cylinder = 10 meters

Cavelieri's Principle states that volume of an oblique cylinder is same as the volume of right circular cylinder with equal radius and height.

As we know the formula for "Volume of cylinder":

[tex]Volume=\pi r^2h\\\\V=\frac{22}{7}\times 8\times 8\times10\\\\V=\frac{14080}{7}\\\\V=2011.43[/tex]

Hence, Volume of an oblique cylinder is 2011.43 sq.m.

Mah problem, in class no substitute beed help

Answers

You need the greatest common factor of the two numbers.

First, we find the prime factorization of each number.

72/2 = 36
36/2 = 18
18/2 = 9
9/3 = 3
3/3 = 1

72 = 2^3 * 3^2

90/2 = 45
45/3 = 15
15/3 = 5
5/5 = 1

90 = 2 * 3^2 * 5

To find the GCF, use only common factors with the lower exponent.

Both 72 and 90 have 2 as a factor. 72 has 2^3, and 90 has 2. 2 has a lower exponent than 2^3, so we use 2.

Both 72 and 90 have 3 as a factor. The both have 3^2, so we use 3^2.

90 has 5 as a factor, but 72 does not, so 5 is not a common factor, so we do not use 5.

The GCF is the product of the factor we use.

GCF = 2 * 3^2 = 2 * 9 = 18

Answer: The greatest number of students he can place in a row is 18.

x>2 because you first divide 3 by 3, to cancel out the 3 and what you do to one side you do to the other. So you divide 6 by three which equal 2. This process is to isolate the x, so you can somewhat determine what x is. Therefore x is greater than 2, x>2


The Philips family had 3 cats. They needed to split 20 ounces of cat food among the three cats. How much cat food would each cat get? between what two whole numbers does your answer lie?

Answers

Final answer:

Each cat would get approximately 6.67 ounces of cat food, which falls between 6 and 7 ounces. The calculation is done by dividing the total amount of food (20 ounces) by the number of cats (3).

Explanation:

The Philips family had to split 20 ounces of cat food among their 3 cats. To find out how much food each cat gets, we need to divide the total amount of food by the number of cats. Calculating this, 20 ounces ÷ 3 cats equals approximately 6.67 ounces per cat. Even though this is a decimal, if we consider whole numbers, the amount each cat gets falls between 6 and 7 ounces, since 6.67 is more than 6 and less than 7.

When dealing with fractions and division, it's essential to understand the concept of division and be able to find averages. The task at hand may often find itself related to dividing a quantity evenly among a number of recipients, much like in scenarios where we have to split a pie or determine individual portions.

Final answer:

To divide 20 ounces of cat food equally among three cats, each cat gets approximately 6.67 ounces. The amount of food per cat lies between the whole numbers 6 and 7.

Explanation:

The question is asking how to divide 20 ounces of cat food equally among three cats. To find out how much each cat would get, you divide the total amount of cat food by the number of cats:

Determine the total amount of food: 20 ounces.Count the number of cats: 3 cats.Divide the total amount of food by the number of cats: 20 ounces ÷ 3 cats = approximately 6.67 ounces per cat.

This calculation shows that each cat would get approximately 6.67 ounces of food. This value lies between the whole numbers 6 and 7. Therefore, when the Philips family divides the cat food, each cat gets a little more than 6 ounces but less than 7 ounces of food.

16 divided by 12.99 = $1.23
now you will divide 37.01 divided by 1.23
37.01 divided by 1.23 = about 30 
this means youll get about 30 single tracks with your gift card.
let me know if you have any further questions
:)

Final answer:

After purchasing an album for $12.99 from the $50 gift card, the remaining balance is $37.01, which allows the purchase of 37 more single tracks, assuming each track costs $1.

Explanation:

To determine how many songs can be bought with a $50 gift card after purchasing an album for $12.99, we need to subtract the cost of the album from the total amount on the gift card. So, we have:

Total amount on gift card: $50Cost of album: $12.99

Subtracting the cost of the album from the gift card amount gives us:

$50 - $12.99 = $37.01

Assuming that each single track costs $1 as per the scenario provided, we can divide the remaining balance by the cost per single track:

$37.01 ÷ $1 per track = 37 tracks

This means that you can purchase 37 more single tracks with the remaining balance on the gift card.

7b divided by 12=4.2 what is b

Answers

Final answer:

To solve for b in the equation 7b divided by 12 equals 4.2, multiply both sides by 12 and then divide by 7, resulting in b being equal to 7.2.

Explanation:

To solve the equation 7b ÷ 12 = 4.2 for b, we must isolate b on one side of the equation. We can begin by multiplying both sides of the equation by 12 to cancel out the division by 12 on the left side. This results in the equation 7b = 4.2 × 12. To find the value of b, we then divide both sides of the equation by 7:

Multiply both sides by 12: 7b ÷ 12 × 12 = 4.2 × 12Simplify: 7b = 50.4Divide both sides by 7: 7b ÷ 7 = 50.4 ÷ 7b = 7.2

Therefore, the value of b is 7.2.

Final answer:

To find the value of b in the equation 7b/12 = 4.2, multiply both sides by 12 and then divide by 7 to get b = 7.2. The value of b is 7.2.

Explanation:

The student is asking how to find the value of b in the equation 7b divided by 12 equals 4.2. To solve for b, you can follow these steps:

Write down the original equation: 7b / 12 = 4.2.Multiply both sides of the equation by 12 to eliminate the denominator: 12 * (7b / 12) = 12 * 4.2, which simplifies to 7b = 50.4.Divide both sides by 7 to solve for b: 7b / 7 = 50.4 / 7, which gives b = 7.2.

Therefore, the value of b is 7.2.

B. infinitely many solutions
C. no solution

Answers

The system of equations 4x-y=4(x+1) and y=6 has no solution.

To determine the solution(s) of the system of equations, let's analyze each equation:

Equation 1: 4x - y = 4(x + 1)

Equation 2: y = 6

To simplify Equation 1, we can distribute 4 on the right side:

4x - y = 4x + 4

By rearranging terms, we have:

- y = 4

Comparing Equation 2 with this result, we see that the two equations are contradictory. Equation 2 states that y = 6, while the modified Equation 1 states that y = -4. This means there is no value of y that can simultaneously satisfy both equations.

Thus, the system of equations has no solution.

Therefore, the correct answer is C. no solution.

What is the completely factored form of x2y – 2xy – 24y?

Answers

Factoring the expression we proceed as follows:
x^2y-2xy-24y
this can be simplified to:
x^2y-xy-xy-24y
=xy(x-1)-y(x-24)

Answer:

C: y(x + 4)(x – 6)

I need some help what 9 + 10?

Answers

9 + 10 will equal 19
19, because if let's say you took 9 blocks, added 10, and counted them all, 19 would be the answer

Write 4/10 as a fraction with a denominator of 100. Then write 4/10 as a decimal.
Would it be 4/100 or 40/100? The decimal would be 0.4 ?

Answers

4/10 = (4x10)/(10x10) = 40/100

4/10 = 0.4

Since there is one real root and one complex root, there must be one additional real root and another complex root that is the conjugate of the one given.

The conjugate complex roots give rise to the factor
.. (x -2 -5i)*(x -2 +5i)
.. = (x -2)^2 +25
.. = (x^2 -4x +29)

The given real root gives rise to the factor 
.. (x +2)

The remaining factor can be written as
.. (ax -3)
since we know the product of the constant terms in these factors must be -174.

The product of these factors is
.. (x +2)(x^2 -4x +29)(ax -3)
.. = ax^4 -(2a +3)x^3 +(21a +6)x^2 +(58a -63)x -174

Matching x-coefficients, we have
.. 53 = 58a -63
.. 116 = 58a
.. 2 = a


(a) The factored function is
.. f(x) = (x +2)(x^2 -4x +29)(2x -3)


(b) The values of a, b, c are ...
.. a = 2
.. b = -(2a +3) = -7
.. c = 21a +6 = 48

(a, b, c) = (2, -7, 48)

2. Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the quadrilateral. Show your work.

Answers

A cyclic quadrilateral is a quadrilateral whose vertices all touch the circumference of a circle.

Opposite angles in a cyclic quadrilateral add to 180 degrees. Quadrilateral ABCD is a cyclic quadrilateral.

< A+<C=180

Substituting <A and <B values given in figure:

x+2+x-2=180

Adding like terms:

2x=180

Dividing both sides by 2

x=90°

<A=x+2=90+2=92°

<C=x-2=90-2=88°

<D=x-10=90-10=80°

<B+<D=180

<B=180-80=100°

The angles of the quadrilateral ABCD are

<A=92°

<B=100°

<C=88°

<D=80°

the area of this circle is 72π m^2 what is the area of a 45° sector of this circle

Answers

A 45° sector is 1/8 of the area of the circle, so is (72π m^2)/8 = 9π m^2.
