Answer:

Your answer would be

- 2/25 x^3a^3

Or vice versa with the variables

- 2/25 a^3x^3

TO solve it’s pretty simple if you do it correctly.

So with all the variables in the two multiples, you can find a way to combine them

So ignoring everything else you’d get

a^2x * x^2a

You we can see the difference,

theres a^2 and a

Whilst there is also x^2 and x

Now we can combine them

a^3 x^3

Now we can do the normal multipacation with the fraction

2/5 * - 1/5 which is -2/25

Now combine

ANd you got it :D

Vector d is shown on a centimetre grid. Image attached.
nexus9112 [7]

Answer:

see explanation

Step-by-step explanation:

A column vector has the form \left[\begin{array}{ccc}x\\y\\\end{array}\right]

Following the direction of the arrow , the x- displacement = - 3 and y- displacement = 2 , then column vector is

\left[\begin{array}{ccc}-3\\2\\\end{array}\right]

h + k

= \left[\begin{array}{ccc}4\\-3\\\end{array}\right] + \left[\begin{array}{ccc}-2\\-1\\\end{array}\right] ← add corresponding elements from each vector

= \left[\begin{array}{ccc}4-2\\-3-1\\\end{array}\right]

= \left[\begin{array}{ccc}2\\-4\\\end{array}\right]

Kedwin has $150.00 and wants to buy a new pair of headphones that cost $175.00 plus 10% shipping. He decides to wait until the h
cestrela7 [59]

Answer:

He needs to wait for a 30% discount (or more)

Step-by-step explanation:

175x110%=192.5

So that's how much it originally costs.

192.5x70%=134.75

134.75x110%= 148.225 (since you also need to add in shipping)

Find f(x) and g(x) so that the function can be described as y = f(g(x)). (5 points) y = eight divided by square root of quantity
zubka84 [21]

Answer:

  • f(x) = 8/√x
  • g(x) = 2x+4

Step-by-step explanation:

For this sort of problem, there can be an infinite number of answers.

It can be convenient to choose one of the simpler answers by looking at the operations that are performed on the variable. Here, you have ...

  • 2 multiplies it
  • 4 is added to the product
  • the square root is taken
  • 8 is divided by that root

You can work from the bottom up and define the outer function (f(x)) to be any of these operations. In our answer above, we have elected to include the "square root" and the "8 divided by that root" in our definition of f.

Then our function g takes care of the other operations.

The first term of a sequence is -5, and the common difference is 10. What are the next three terms?
Galina-37 [17]

Let the first term be <em>a</em>

Given, a = -5

d = 10

So, we need to find next three terms i.e. second, third and fourth terms.

Using \: formula \:  =  >   a_{n} = a + (n - 1)d

a _{2} =  - 5 + (2 - 1)10 \\  =  - 5 + 10 = 5 \\ a _{3} =  - 5 + (3 - 1)10 \\  =  - 5 + 20 = 15 \\ a _{4} =  - 5 + (4- 1)10 \\  =  - 5 + 30= 25
