Answer:

SA = 10,800 ft²

Step-by-step explanation:

To find the surface area of a rectangular prism, you can use the equation:

SA = 2 ( wl + hl + hw )

SA = surface area of rectangular prism

l = length

w = width

h = height

In the image, we are given the following information:

l = 40

w = 60

h = 30

Now, let's plug in the information given to us to solve for surface area:

SA = 2 ( wl + hl + hw)

SA = 2 ( 60(40) + 30(40) + 30(60) )

SA = 2 ( 2400 + 1200 + 1800 )

SA = 2 ( 5400 )

SA = 10,800 ft²

Derivatives are mathematical operators that represent the rate of change of a function with respect to its independent variable. The partial derivatives are equal, this vector field is conservative.

A vector field is a mathematical construct that assigns a vector to each point in a given space. It describes the direction and magnitude of a vector quantity at every point in space. In other words, it associates a vector with each point in a region.

Vector fields can be represented graphically using vector arrows or symbolically using mathematical expressions. They are commonly used in physics, engineering, and mathematics to model physical phenomena such as fluid flow, electric and magnetic fields, and gravitational forces.

To determine if a vector field is conservative, we need to check if it satisfies the criteria for being conservative, which is the existence of a scalar potential function.

A vector field is conservative if it can be expressed as the gradient of a scalar potential function. In other words, if we can find a scalar function such that the vector field is the gradient of that function.

If we have the vector field F = (P, Q), where P and Q are the components of the vector field, we can check if it is conservative by taking the partial derivatives of P and Q with respect to their respective variables (x and y) and see if they are equal. If the partial derivatives are equal, then the vector field is conservative.

For example, if we have the vector field F = (2x, 3y), we take the partial derivatives:

∂P/∂y = 0

∂Q/∂x = 0

Since the partial derivatives are equal, this vector field is conservative.

So, based on the given vector fields, we need to check if each one satisfies the criteria for being conservative by taking the partial derivatives and comparing them.

The Taylor polynomial Ts(x) is 0.974, and the maximum possible error is 0.000026.

The Taylor polynomial Ts(x) is an approximation of a function using its Taylor series expansion. In this case, we are computing the Taylor polynomial for the function f(x) = cos(x) centered at a = 0. The Taylor polynomial Ts(x) represents an approximation of cos(x) using a polynomial of degree s.

By evaluating Ts(0.225), we find that it is equal to 0.974, rounded to six decimal places. This means that Ts(0.225) is an approximation of cos(0.225) with an error term.

To determine the maximum possible size of the error, we use the error bound formula. The error bound formula states that the absolute value of the error between f(x) and Ts(x) is bounded by the maximum value of the (s+1)-th derivative of f(x) on the interval [a, x] divided by (s+1)!, multiplied by the absolute value of (x - a)^(s+1).

In this case, since a = 0, x = 0.225, and s = 1, we can calculate the error bound. By evaluating the second derivative of cos(x), we find that the maximum value on the interval [0, 0.225] is 1. The absolute value of (0.225 - 0)^(1+1) is 0.050625. Therefore, the maximum possible error is 1 * 0.050625 / (1+1)! = 0.000026, rounded to six decimal places.

Thus, the Taylor polynomial Ts(0.225) is 0.974, and the maximum possible error is 0.000026.

The correct statements are,

m∠R > 90°

m∠S + m∠T < 90°

m∠R > m∠T

m∠R > m∠S

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Here, RST is a triangle,

Therefore,  

m∠R + m∠S + m∠T = 180°

⇒ m∠S+m∠T = 180° - m∠R

Since, m∠R > m∠S + m∠T

⇒ - m∠R < - (m∠S + m∠T) (by multiplying-1 on both sides)

⇒ 180°- m∠R < 180° - (m∠S + m∠T) (by adding 180° on both sides)

⇒ m∠S+m∠T < 180° - (m∠S + m∠T)

⇒ m∠S+m∠T+ m∠S+m∠T < 180° ( by adding m∠S + m∠T on both sides)

⇒ 2(m∠S+m∠T) < 180°

⇒ m∠S+m∠T < 90°

⇒ m∠R > 90° ( because m∠R+m∠S+m∠T = 180° )

Again, m∠R > m∠S + m∠T

⇒ m∠R > m∠S and  m∠R > m∠T

Thus, Option first second fourth and fifth are correct.

Since, m∠S = m∠T is only possible when m∠R=90° (but it is not given)

That is why m∠S = m∠T is not correct.

And, there are not enough information to prove m∠S > m∠T

That is why  m∠S > m∠T is also incorrect.

The expected value for each set of 50 items that Sammi sells is $1.82.

The expected value can be calculated by multiplying the profit from each successful sale by the probability of making that sale, and then subtracting the expected cost of each defective item.

Expected value = (Profit from each successful sale * Probability of making that sale) - (Expected cost of each defective item)

Let's assume that Sammi plans to sell 50 items. So, the probability of a successful sale is 49/50 = 0.98. The expected cost of each defective item is $7.

Expected value = ($2 * 0.98) - ($7 * 1/50) = $1.96 - $0.14 = $1.82

So, the expected value for each set of 50 items that Sammi sells is $1.82.

Trust me bro;)

After solving, the remainder when \(-x+3x^2-1\)  is divided by x + 1 is 3.

In the given question, we have to find the remainder when \(-x+3x^2-1\)  is divided by x + 1.

The given polynomial is \(-x+3x^2-1\).

We have to find the remainder of the polynomial when we divide this polynomial x + 1.

To find the polynomial we equate x+1 equal to zero to find the value of x.

x + 1 = 0

x = -1

Now putting x = -1 in the given equation \(-x+3x^2-1\).

P(x) = \(-(-1)+3(-1)^2-1\)

P(x) = 1 + 3×1 - 1

P(x) = 1 + 3 - 1

P(x) = 3

Hence, the remainder when \(-x+3x^2-1\)  is divided by x + 1 is 3.

C = 7.72 ~ 7.7

Step-by-step explanation:

So when you solve this equetion you must 1st find x then c

we can find x by using cos(60)

cos(60) = x/14

x = cos(60) × 14

x = 1/2 ×14

x = 7

so after we find x we are going to solve c by using cos (25)

cos (25) = X/C = 7/c

cos(25) × C = 7

C = 7/cos (25)

C = 7.72 ~ 7.7

so the solution is 7.7

Take for instance, the new function is:

\(h = -at^2 + bt + c+ 1\)

The functions \(h = -at^2 + bt + c\) and \(h = -at^2 + bt + c+ 1\) are different, and both functions will have different intercepts and vertices.

In order to turn -2x + 10y = 2 into slope-intercept form:

First, as we know, the generic slope-intercept form is:

y= mx + b

where m is the slope and b is the y-intercept

Going back to our equation:

-2x + 10y = 2

Adding +2x to both sides:

-2x + 2x + 10y = 2 + 2x

Adding similar terms:

10y = 2 + 2x

Dividing both sides by 10:

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

Simplifying:

y = 1/5 + x/5 --> Slope-intercept form

Answer:

f(x) = \(2(\frac{1}{2})^x\)

Step-by-step explanation:

Let the exponential function is,

f(x) = a(b)ˣ

Since, the given graph passes through two points (0, 2) and (1, 1)

For point (0, 2),

2 = a(b)⁰

2 = a

For point (1, 1),

1 = a(b)¹

ab = 1

2(b) = 1

b = \(\frac{1}{2}\)

Therefore, equation of the exponential function will be,

f(x) = \(2(\frac{1}{2})^x\)

Step-by-step explanation:

to find any side of a right triangle we usually find it by using the pythagrean theory, which states that; a² ± b² = c²

so, 3² + 10² = c².......... note that (c) is the hypotenuse.

so, 9 + 100 = c²

109 = c²

find the square root of both sides.

√109 = √c²

so, 10.44030..... = c

Step-by-step explanation:

To determine the number of ways the letters in the word "payment" can be arranged using 5 letters, we can utilize the concept of permutations.

A permutation is an arrangement of objects where the order matters. In this case, we want to arrange the letters of the word "payment" using only 5 out of the 7 letters available. To calculate the number of arrangements, we use the formula for permutations: nPr = n! / (n - r)!, where n is the total number of objects (letters) and r is the number of objects to be selected (5 in this case).

In the word "payment," there are 7 letters. Therefore, we have 7 options to choose from for the first position, 6 options for the second position, 5 options for the third position, 4 options for the fourth position, and 3 options for the fifth position. Hence, the number of arrangements is:
7P5 = 7! / (7 - 5)! = 7! / 2! = 7 * 6 * 5 * 4 * 3 = 2,520. Therefore, there are 2,520 different ways to arrange the letters of the word "payment" using only 5 letters.

\(\dfrac{v}{u}+\dfrac{u}{v}=\dfrac{u^2+v^2}{uv}=\dfrac{(u+v)^2-2uv}{uv}=\dfrac{(u+v)^2}{uv}-2\)

And we know that

\(u+v=-\dfrac{5}{3}\\\\uv=\dfrac{7}{3}\\\\\\as \ \ (x-u)(x-v)=x^2-(u+v)x+uv\)

So it comes

\(\dfrac{v}{u}+\dfrac{u}{v}=\dfrac{5^2*3}{7*3^2}-2=\dfrac{25-42}{21}=-\dfrac{17}{21}=-0.80952...\)
