1.234, 1.244 , and 1.247 from greatest to least?

Answer:

5.5cm

Step-by-step explanation:

The volume of a cuboid is given by

V = lbh

where l is the length

b is the breadth

h is the height.

We know that

V = lbh = 440 cm^3

Given l = 10 cm, h = 8 cm

So, we can find b by substituting these values in the above equation

440 = 10 * b * 8

Solving for b, we get:

b = 440 / (10*8)

b = 5.5cm

So, the breadth of the cuboid is 5.5 cm.

The population of Calculus City can be modeled by an exponential function, g(t) = 10(1.3) ^t, where t is the number of years since 2019. Evaluating g (6) means calculating the population of Calculus City after 6 years, which is 10(1.3) = 39.5 thousand people.

(a) The population of Calculus City can be modeled by an exponential function, g(t) = 10(1.3) ^t, where t is the number of years since 2019.

(b) g (6) = 10(1.3) = 46.6 thousand. This means that the population of Calculus City will be 46.6 thousand in the year 2025.

(c) Solving the equation g(t) = 16.9 yields t = log1.3(16.9/10) = 4.7 years. This means that the population of Calculus City will be 16.9 thousand in the year 2023.7.

a. The table for the weekly weight of Julie is illustrated below.

b. The recursive definition for this sequence is y = 180 - 2x.

An equation is written in the form of variables and constants separated by the operation of multiplication and division,

An equation states that terms in different forms on both sides of the equality sign are equal.

Multiplication and division do not separate the terms of an equation.

Given, Julie is trying to lose weight.

She now weighs 180 pounds and every week for eight weeks, she was able to lose 2 pounds.

The list of her weight every week for eight weeks is,

week 1 = 180 - 2 = 178 pounds.

week 2 = 178 - 2 = 176 pounds.

week 3 = 176 - 2 = 174 pounds.

week 4 = 174 - 2 = 172 pounds.

week 5 = 172 - 2 = 170 pounds.

week 6 = 170 - 2 = 168 pounds.

week 7 = 168 - 2 = 166 pounds.

Answer:

First, find out how many guests have ordered chicken: 240 guests * 3535/10000 = 84 guests

Then subtract that number from the total number of guests to find the number of guests who haven't ordered chicken: 240 guests - 84 guests = 156 guests

Then find how many of those guests have ordered gluten-free meals: 156 guests * 12.5% = 19.5 guests

Then round down the number of guests who have ordered gluten-free meals to the nearest whole number to find the exact number of guests who ordered gluten-free meals: 19 guests

Then subtract that number from the number of guests who haven't ordered chicken to find the number of guests who haven't ordered their meals yet: 156 guests - 19 guests = 137 guests

So 137 people haven't ordered their meals yet.

If their assembly rates continue, based on an equation, Summer will catch up with Jin in 52 minutes.

An equation refers to a statement claiming the equality of two or more mathematical expressions.

Using the equation sign (=) mathematicians show that expressions are equal or equivalent.

Jin's assembling rate per minute = 12 parts

Summer's assembling rate per minute = 15 parts

The number of parts already assembled by Jin before Summer started = 156 parts

Let the minutes used by Jin or Summer = n

The total parts assembled by Jin in n minutes = 156 + 12n

The total parts assembled by Summer in n minutes = 15n

For Summer to catch up to Jin, 15n = 156 + 12n

Grouping like terms:

15n - 12n = 156

3n = 156

n = 52

Thus, in 52 minutes, the number of assembly parts by Summer will equal Jin's.

Answer: Let x be the original cost of the jersey.

We know that the jersey was on sale at a 30% discount, so the sale price is x - (30/100)*x = x(1- 0.3) = 0.7x

We also know that Tyrone spent a total of $83.39 and the hat cost $37.89, so the jersey cost is 83.39 - 37.89 = 45.5

So we can write the equation:

0.7x = 45.5

To find the original cost of the jersey, we can divide both sides by 0.7:

x = 45.5 / 0.7

x = 65

So the original cost of the jersey is $65.

So. the left Riemann sum is 23.74 ft^2.

Given the information in the table:

(a) To use a left Riemann sum with three subintervals to approximate the integral of A(h) with respect to h, we need to divide the interval of integration [0,10] into three equal subintervals. The width of each subinterval is (10-0)/3 = 3.33 ft. The left Riemann sum can be calculated as:

(A(0) * 3.33) + (A(2) * 3.33) + (A(5) * 3.33) = (50.3 * 3.33) + (14.4 * 3.33) + (6.5 * 3.33) = 16.80 + 4.78 + 2.16 = 23.74 ft^2

(b) This approximation represents the total area of the horizontal cross section of the tank up to a specific height h.

(c) The Riemann sum is an underestimate of the actual integral. This is because the Riemann sum uses the left endpoint of each subinterval to approximate the area under the curve, but the actual area under the curve is always greater than or equal to the area of the rectangles.

Answer:

  z = √30

Step-by-step explanation:

Given similar right triangles with hypotenuse segments marked 3 and 7, you want to know the length of short leg z adjacent to the segment marked 3.

The fact that all of these triangles are similar gives rise to some "geometric mean" relationships:

  hypotenuse/short side = 10/z = z/3

  30 = z² . . . . . . . multiply by 3z

  z = √30 . . . . . . take the square root

__

Additional comment

The other two geometric mean relations are ...

  x = √(7·10) . . . . . hypotenuse/long side: 10/x=x/7

  y = √(7·3) . . . . . . short side/long side: y/7=3/y

The triangles are similar by AA: each has a right angle, and an angle in common with the largest triangle. Triangles similar to the same triangle are similar to each other.

The lines L₁ and L₂ given by the vector equations is perpendicular.

In order to prove that the lines are perpendicular,

L₁: r(t) = (-5+ 3t)i + (3 + t)j

L₂: r(s) = (2+2s)i + (4 - 6s)j

To determine whether the lines L₁ and L2 are parallel, perpendicular, or neither, we need to compare their direction vectors.

The direction vector for L₁ is given by <3,1> and the direction vector for L₂ is given by <2,-6>.

The dot product of the direction vectors is (32) + (1-6) = -8. Since the dot product is zero, the vectors are perpendicular, and therefore the lines are perpendicular.

The predicted value of y when I = 5 is equal to D) 30.

To determine the predicted value of y when I = 5, we can use the equation of the simple linear regression model:

y = b0 + b1x

where b0 and b1 are the regression coefficients and x is the predictor variable.

We can find b1 using the formula:

b1 = r(Sy/Sx)

where r is the sample correlation coefficient, Sy is the standard deviation of the y variable, and Sx is the standard deviation of the x variable.

Plugging in the given values:

b1 = -0.98(8/2) = -4

We can find b0 using the formula:

b0 = ybar - b1*xbar

where ybar and xbar are the mean of the y variable and the x variable respectively.

Plugging in the given values:

b0 = 10 - (-4)*10 = 50

Therefore, the equation of the simple linear regression model is:

y = 50 - 4x

So when I = 5, the predicted value of y is:

a) The block-spring system has an elastic potential energy equal to 2.517 joule.

b) The block has speed of approximately 1.513 meters per second.

In this problem we must analyze the energy and kinematics of spring-block system with no irreversibilites (no friction). Part A - Elastic potential energy is determined when spring is entirely deformed:

U = (1 / 2) · k · x²

Where:

If we know that k = 895 N / m and x = 0.0750 m, then the elastic potential energy of the block-spring system is;

U = (1 / 2) · (895 N / m) · (0.0750 m)²

U = 2.517 J

The elastic potential energy of block-spring system is 2.517 joule.

Part B - And the speed can be determined by principle of energy conservation and work-energy theorem:

K = U

Where K is translational kinetic energy, in joules.

(1 / 2) · m · v² = U

v² = 2 · U / m

v = √(2 · U / m)

If we know that U = 2.517 J and m = 2.20 kg, then the speed of the block is:

v = √[2 · (2.517 J) / (2.20 kg)]

v ≈ 1.513 m / s

The solution of the system of equations is given by the ordered pair (10, 85).

The solution tells us that the height of both Drone A and Drone B would be the same after 10 minutes.

In this scenario, heights of drones are represented by the following system of equations:

y = 8x + 5     .......equation 1.

y = 6x + 25    .......equation 2.

where:

By equating equation 1 and equation 2, number of minutes since the drones were released can be calculated as follows;

8x + 5 = 6x + 25

8x - 6x = 25 - 5

2x = 20

x = 20/2

x = 10 minutes.

Next, we would determine the height when x = 10 minutes:
