Answer:

Matrices are a useful way to represent, manipulate and study linear maps between finite-dimensional vector spaces (if you have chosen basis).

Matrices can also represent quadratic forms (it's useful, for example, in analysis to study hessian matrices, which help us to study the behavior of critical points).

Cindy has decided to lease a car. the lease includes a money factor of 0.00354. what interest rate is cindy being charged in her
Liono4ka [1.6K]

The interest rate Cindy will be charged with money factor 0.00354 is approximately 8.5% which is option b.

Given The factor included in lease is 0.00354.

Interest is the amount that a bank or person who gives loan charges from loan taker.

Money factor is a method for finding the financing charges on a lease with monthly payments. The money factor can be translated into the annual percentage rate by multiplying the money factor by 2400.

Money factor=0.00354.

So the interest rate that Cindy will charge is equal to 2400*0.00354

The interest rate Cindy will be charged =8.496%

=8.5%

Hence the interest rate charged is approximately 8.5%.

Find​ f(x) and​ g(x) such that ​h(x)equals​(fcircle​g)(x). h left parenthesis x right parenthesis equals left parenthesis 2 x pl
GaryK [48]

Answer:

  • f(x) = x^3
  • g(x) = (2x+4)^2

Step-by-step explanation:

There are many ways to decompose h(x) into f(x) and g(x). The main purpose of the exercise seems to be to get you to think about the operations that are performed on x, then divide that list of operations into two parts.

In the function ...

  h(x) = (2x +4)^6

the variable x is ...

  • multiplied by 2
  • 4 is added to the sum
  • the sum is raised to the 6th power

Of course, the 6th power can be considered as the cube of a square or the square of a cube, if you like.

In the decomposition shown in the answer above, we have chosen to put most of this list in g(x), including the square of the sum. Then we have made f(x) be the cube of that square.

  h(x) = f(g(x)) = (2x+4)^6

When f(x) = x^3, this is ...

  h(x) = f(g(x)) = g(x)^3 = ((2x+4)^2)^3

so ...

  g(x) = (2x+4)^2 . . . and . . . f(x) = x^3

_____

Other possible decompositions are ...

  • g(x) = 2x
  • f(x) = (x+4)^6

or

  • g(x) = (x+2)
  • f(x) = (2x)^6

or

  • g(x) = 2x+4
  • f(x) = x^6

or ... (many others)

What is the unit rate of 13/2 pounds per 3/4 quart?
kodGreya [7K]

Answer:

26/3 or 8.66666 (8.6 with a line over the 6)

Step-by-step explanation:

According to the problem, 13/2 pounds is only 3/4 of a quart. A unit rate, however, has a denominator value of 1. To solve this question, we must change the value of 3/4 to 1.

The first step to this is changing 3/4 to 1/4. This means affecting the value 13/2 pounds. 1/4 is a third of 3/4. We must find a third of 13/2 to properly change this relationship. So, we should do 13/2 ÷ 3. This can also be written as 13/2*3. So, a third of 13/2 is 13/6. Our new relationship is 13/6 pounds = 1/4 quart.

Now, we can multiply 13/6 and 1/4 by 4 to get ? and 4/4, or 1. We can multiply the numerator by 4 to finish this step. 13/6 becomes 13*4/6, which equals 52/6. 52/6 can be divided by 2 to simplify the fraction and becomes 26/3.

So, the <em>unit rate of 13/2 pounds per 3/4 quart is 26/3</em>. 26/3 can also be written as 8.66666, or 8.6 with a line over the 6, in decimal form.
