Which expression is equivalent to 36x6z2−−−−−−√36x6z2 when x>0x>0, and z>0z>0?

Answer:

To compare the times of Paul and Jeff, we need to convert Paul's time to seconds.

Paul's time = 2 minutes 2 seconds = (2 x 60) + 2 = 122 seconds

Now we can compare their times:

Paul's time: 122 seconds

Jeff's time: 121 seconds

Jeff finished first since he has the lowest time.

Answer: To compare the times of Paul and Jeff, we need to convert Paul's time to seconds:

2 minutes and 2 seconds = 2 × 60 seconds + 2 seconds = 122 seconds

Now we can compare their times:

Paul finished in 122 seconds

Jeff finished in 121 seconds

Since Jeff's time is lower than Paul's time, Jeff finished first.

Step-by-step explanation:

The present value of the annuity is $189,468.24 if the initial payment is $1,000 and the monthly interest rate is 0.3333%.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

To solve this problem, we need to first find the monthly interest rate since the payments are made monthly. The monthly interest rate can be found by dividing the annual interest rate by 12:

i = 4% / 12 = 0.3333% per month

Next, we need to find the present value of the annuity. We can use the formula for the present value of an annuity-immediate:

[tex]PV = P * (1 - (1 + i)^{-n}) / i[/tex]

where PV is the present value, P is the monthly payment, i is the monthly interest rate, and n is the number of payments.

The first year, the payments are level, so we can use the formula with n = 12 to find the present value of the payments for the first year:

[tex]PV1 = 1000 * (1 - (1 + 0.003333)^{-12}) / 0.003333 = \$11,887.87[/tex]

For the second year, the payments increase by 2%, so the monthly payment for the second year will be:

P2 = 1000 * 1.02 = $1,020

We can then use the formula again with n = 12 to find the present value of the payments for the second year:

[tex]PV2 = 1020 * (1 - (1 + 0.003333)^{-12}) / 0.003333 = \$12,061.92[/tex]

We can continue this process for the remaining 18 years, increasing the payment by 2% each year. The total present value of the annuity is the sum of the present values of each year's payments:

PV = PV1 + PV2 + ... + PV20 = $189,468.24

Therefore, the present value of the annuity is $189,468.24 if the initial payment is $1,000 and the monthly interest rate is 0.3333%.

a. The equation of the tangent plane is z = 1 + x.

b. The point (4/3, 8/3, 5) lies on both the plane T(0,1) and the line l.

c. The other points on the graph of f(x) whose tangent plane contains the line l are (-9/8, -1/2, -21/8) and (-25/32, -3/4, -47/32)

The function is defined as a mathematical expression that defines a relationship between one variable and another variable.

(a) The partial derivatives of f(x) at this point:

∂f/∂x = 2x + y²

∂f/∂y = x² + 2xy

Evaluating these at (0,1), we get:

∂f/∂x(0,1) = 1

∂f/∂y(0,1) = 0

So the equation of the tangent plane is:

z = f(0,1) + ∂f/∂x(0,1)(x-0) + ∂f/∂y(0,1)(y-1)

z = 1 + x

(b)

The plane T(0,1) contains the line l:

2x = y = (z+3)/2

Substituting y = 2x and z = 2y-3, we get:

z = 2(2x) - 3 = 4x - 3

So any point on the line l can be written as (x, 2x, 4x-3).

Substituting these values into the equation of the plane, we get:

4x-3 = 1 + x

3x = 4

So x = 4/3, y = 8/3, and z = 5.

Therefore, the point (4/3, 8/3, 5) lies on both the plane T(0,1) and the line l.

(c) To find all other points on the graph of f whose tangent plane contains the line l, we need to find the intersection of the graph of f with the plane T(0,1) + λ(2,0,1), where λ is a scalar. This gives us the system of equations:

x² + y²xy = 1 + x + 2λ

2x + y² = 0

y - 1 = λ

Solving for x and y in terms of λ, we get:

y = λ + 1

x = -(y²)/2 = -(λ+1)²/2

Substituting these values into the first equation, we get:

(λ+1)² + (λ+1)²(-(λ+1)²/2) = 1 - (λ+1)²/2 + 2λ

Simplifying and solving for λ, we get:

λ = -1/2, -1/4

Therefore, the other points on the graph of f(x) whose tangent plane contains the line l are:

(-9/8, -1/2, -21/8) and (-25/32, -3/4, -47/32)

The total area of the exercise room is 160 square feet.

The number of square yards equivalent to this total area is 17. 78 square yards.

Since the rubber flooring is sold in whole square yards, Juan must purchase exactly 18 square yards.

To find the area of the exercise room, you should divide it into two different rectangles and then add up their areas.

Rectangle 1 length = 16 ft

Rectangle 1 width = ( 13 - 6 ) = 7 ft

Rectangle 2 length = ( 16 - 8 ) = 8 ft

Rectangle 2 width = 6 ft

The area is therefore :

= ( 16 x 7 ) + ( 8 x 6 )

= 160 square feet

1 square yard is 9 square foot so 160 square foot is:

= 160 / 9

= 17. 78 square yards

Step-by-step explanation:

Answer:

The correct answer is: domain: all real numbers, range: all real numbers greater than or equal to -5.

We can see that the function is a polynomial of degree 4, which means it is defined for all real numbers. Also, as x^4 is always non-negative, the minimum value of the function occurs when x=0, and it is f(0) = -4. Therefore, the range of the function is all real numbers greater than or equal to -4. However, since the function is increasing as we move away from 0, the range is actually all real numbers greater than or equal to the minimum value of -4 plus the vertical shift of -1, which is -5.

We may calculate the distance from Carlos and the tree as [tex]D = 781.23[/tex] ft using trigonometric relationships.

Many functions in trigonometry offer excellent illustrations of how calculus may be used in practical situations. By the way, basic trigonometry primarily deals with the algebraic features of circular functions, therefore basic calculus is not always simpler than basic trigonometry. On the other hand, calculus is fundamentally non-algebraic in nature.

The mnemonic SOHCAHTOA makes it simple for us to recall the three primary trigonometric ratios.

Then one of the cathetus of the triangle is equal to:

[tex]275ft - 6ft = 269ft[/tex]

That cathetus is the opposite cathetus to the angle of 19° (the elevation angle). And the adjacent cathetus is the distance between Carlos and the tree.

Then we can use the relation:

Where:

[tex]a=19^{0}[/tex]

opposite cathetus [tex]=269ft[/tex]

adjacent cathetus [tex]=D[/tex]

Replacing that, we get

[tex]tan(19^{0} ) = 269ft/D[/tex]

Solving for D, we get:

[tex]D = 269ft/tan(19^{0} ) = 781.2ft[/tex]

The worker worked 38 + 5 = 43 hours that week.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Let's break this problem down into two parts.

Part 1: Calculating the base pay for the 38 hours worked

The worker earned #80 per hour for a 38-hour week, so the base pay for those 38 hours would be:

Base pay = #80/hour x 38 hours = #3040

Part 2: Calculating the overtime pay for the additional hours worked

To find out how many hours were worked beyond the 38-hour week, we can use the fact that the total pay for the week was #3640. We know that the base pay for 38 hours was #3040, so the remaining #600 must be the overtime pay.

Since the company pays overtime at a time and a half, we can use this to find out how many hours were worked beyond the 38-hour week:

Overtime pay = (#80/hour x 1.5) x (number of overtime hours)

We can rearrange this equation to solve for the number of overtime hours:

Number of overtime hours = Overtime pay / (#80/hour x 1.5)

Number of overtime hours = #600 / (#80/hour x 1.5) = 5

Therefore, the worker worked 38 + 5 = 43 hours that week.

Answer:

To use the Pythagorean Theorem to determine if the triangle is right, acute, or obtuse, we need to find the length of the longest side (also known as the hypotenuse) by squaring each side, adding the results, and taking the square root of the sum.

So,

63^2 = 3969

58^2 = 3364

30^2 = 900

Now, we add 3969 and 3364 to get 7333, and take the square root to get approximately 85.62.

Since 63, 58, and 30 are the lengths of the sides of the triangle, we can compare the length of the longest side (85.62) to the sum of the other two sides (63 + 58 = 121) to determine if the triangle is right, acute, or obtuse.

85.62^2 = 7326.23

121^2 = 14641

Since 7326.23 is less than 14641, the triangle is acute.

If two bakers can make 30 loaves in 1 hour, then we can use proportionality to find how many hours it would take for 3, 5, 6, and 15 bakers to make 30 loaves.

Let h be the number of hours needed for a given number of bakers to make 30 loaves. Then we have:

2 bakers can make 30 loaves in 1 hour, so 1 baker can make 15 loaves in 1 hour.

Therefore:

3 bakers can make 45 loaves in h hours, so 45/3 = 15 loaves can be made in 1 hour. Thus, 3 bakers can make 30 loaves in 2 hours.

5 bakers can make 75 loaves in h hours, so 75/5 = 15 loaves can be made in 1 hour. Thus, 5 bakers can make 30 loaves in 2 hours.

6 bakers can make 90 loaves in h hours, so 90/6 = 15 loaves can be made in 1 hour. Thus, 6 bakers can make 30 loaves in 2 hours.

15 bakers can make 225 loaves in h hours, so 225/15 = 15 loaves can be made in 1 hour. Thus, 15 bakers can make 30 loaves in 2 hours.

Therefore, regardless of the number of bakers, it would take 2 hours to make 30 loaves of bread.
