What is Adding functions

Answers

Answer 1

Answer:

Adding two functions is like plotting one function and taking the graph of that function as the new x-axis. Points of the second function are then plotted with respect to the new axis. For example, (2, 3) becomes "over 2," "up 3 from the new axis," or (3, f + 2).

Another Example:

To add or subtract functions, just add or subtract the values at each point where it makes sense. If the functions are given by formulas, you can just add or subtract the formulas (it doesn't matter whether you plug in values before or after).

Answer:

An easy way to tell with a number like this is that both numbers are round, so they can both be divided by 2

Step-by-step explanation:

You can tell that it is not simplified if they are both even, as they can be divided by 2, or really, if both numbers have a common factor as a divisor.

For example, 3/6 has a common of factor by 3, 3/3 / 3/6 = 1/2.

Ahmed invests $4000 in two different accounts. The first account paid 10 %, the second account paid 9% in
interest. At the end of the first year he had earned $370 in interest. How much was in each account?

Answers

Answer: 3000$ in 9% account

Step-by-step explanation: sums in accounts are x and (4000-x)

Interests are 0.09x and 0.10(4000-x) = 400-0.1x

Now you get 0.09x -0.1x + 400 = 370

Then -0.01x = -30 and x= 3000

A triangle has side lengths of 25in, 30in, and 50 in. Classify it as acute, obtuse, or right. Please help me.

Answers

9514 1404 393

Answer:

  obtuse

Step-by-step explanation:

Using the idea of a "form factor", we find ...

  f = a² + b² - c²

  f = 25² +30² -50² = 625 +900 -2500 = -975

The form factor is negative, so the triangle is obtuse.

_____

Additional comment

The form factor, as defined above, classifies the triangle according to its sign:

  f > 0 . . . acute

  f = 0 . . . right

  f < 0 . . . obtuse

The largest angle in the triangle can be found from ...

  cos(C) = f/(2ab)

Here, it is C = arccos(-975/1500) ≈ 130.5416°

Answers

There’s 36 that use both so put that in the middle. The TOTAL amount of people using the fitness suite is 57 so to find just that side you subtract 36 from 57 to get 21. Same thing with 49 and you get 13. Add all of them up and you get 70. 100-70=30. 30 people use neither so they go outside of the circles :)

A Mustang GT on Missouri has a marked price of $60,000. If paid in cash you are to pay 15% less than the marked price. It also have a hire purchase plan which states to pay 30% of the marked price and $1000 monthly payments for 4 yrs.
A) Discount on Cash price.
B) Cash Price.
C) Amount Payable.
D ) Hire Purchase Price
E ) Difference between the Hire Purchase price and the Cash Price.

Answers

Answer:

A) Discount on Cash price. ($9,000 )

B) Cash Price. ($51,000 )

C) Amount Payable. ($51,000 )

D ) Hire Purchase Price ($66,000 )

E ) Difference between the Hire Purchase price and the Cash Price. ($15,000 )

Step-by-step explanation:

The following is the workings:

The GT Missouri marked price = $60,000

If paying cash,

Discount = 15%

(15/ 100 ) x $60,000 = $9,000

Actual Price (less discount) = $60,000 - $9000 = $51,000

If hire purchase,

Firstly, 30% marked price,

= (30/100) x $60,000 = $18,000

Monthly payment = $1000

Period = 4 years = 4 x 12 = 48 months

Total monthly payment,

$1000 x 48 = $48, 000

Therefore, total hire purchase payment

Monthly payment + initial 30% payment

= $18,000 + $48,000 = $66,000

Difference between hire purchase and cash price,

= $66,000 - $51,000 = $15,000

O C. H=kL

OD. H=*
b) H= |(Type an integer or a decimal.)

Answers

Answer:

i) The variation equation     H =  k L

ii) The value of H = 20

iii) C)  H = k L

Step-by-step explanation:

Step(i):-

Given that H varies directly as L

                    H ∝ L

                   H =  k L

Given that H =30 and L = 60

          ⇒   30 = k (60)

            [tex]k = \frac{30}{60} = \frac{1}{2}[/tex]

Step(ii):-

Given that L = 40

The variation of the equation = H = k L ...(i)

 put L = 40 in equation (i)

 [tex]H = \frac{1}{2} X 40 = 20[/tex]
