To find the value of the calculator after 5 years, you need to find how much the price of the calculator drops each year. From years 0 to 2, it seems that the price of the calculator has dropped by some amount of money x. To find how much the calculator drops each year, first you will need to subtract 160 from 225 (225-160) to get 65. Next, you need to divide 65 by 2 (65/2) to get $32.50.

I believe that in order to find the price after 5 years, you will need to multiply 32.5 by 5 (32.5*5) to get $162.50. Next you would subtract $162.50 from $225 (225.00-162.50) to get $62.50.

So, the price of the calculator after 5 years is $62.50!

I hope this helps!

State the various transformations applied to the base function f(x)=|x| to obtain a graph of the function g(x) = |x| − 2.
Molodets [167]

Horizontal shift of 1 unit to the left and a vertical shift downward of 2 units.

<h3>Transformation of function</h3>

Transformation technique is a way of changing the position of an object on an xy-plane.

Given the parent function of a modulus function f(x) = |x|, the graph of the function g(x) = |x| - 2 shows a vertical translation of the parent function down by 2 units.

The resulting graph of the translated function is as shown below

Answer: Area of Δ DUO = 12.0 square units.

Step-by-step explanation:

From the diagram, Δ DPA is a right angled triangle and right angled at P.

Therefore ∠D will be

Tan ∅° = PA/DP ie, opposite side all over the adjacent.

            = 4.5/3.75

Tan∅°   = 1.2

to calculate ∅°, we know find the inverse of Tan 1.2

∅ = Tan^-1 1 .2 from your log tables or calculator

         ∅° = 50.20°.

               = 50°

Since line DR is ⊥ to line OP

∠ADR = 90° - 50°

            = 40°.

From the diagram,

     ∠ADR = ∠UDR = 40°

Therefore,

    ∠ODU = 180 - ( 40 + 40 + 90 )  { Angle on a straight line }

                 = 180 - 170

                 = 10°

From Δ UDM , line MU is he height of the required Δ DUO whose area is to be determined.

Now find the height MU

            Tan10.0° = MU/10, where MU is the opposite side and 10.0 is the adjacent from the diagram given.

             MU = Tan10.0 x 10.0

                    =  0.1763 x 10.0

                    =  1.763

Therefore to calculate the area of Δ DUO

                    =   1/2 x base x height

                    = 1/2 x line OD x line MU

                    = 1/2 x 14.0 x 1.763

                    = 7 x 1.763

                    = 12.341

                    = 12.0 square units.

         

           =

Yuliya22 [10]

Answer:

x intercepts there are three and y intercept in 0

Step-by-step explanation:

so  f(x)=a(0+3)(x-2)^2(x-2)

-2=a(3)(4)(-2)

-2=a(-10)

a=5

rewrite

f(x)=5(x+3)(x-2)^2(x-2)

6*10 =$60 for sugar sticks
14*8=$112 for jelly beans

Thus, $60 + $112 = $172 for overall candy mixture.
