Solve 5 – b = 2t for t.

Answers

Basically solving for t is like flipping the equation B= -2t+5

Answer:

[tex] \rm t = \dfrac{5 - b}{2} [/tex]

Step-by-step explanation:

Solve for t:

[tex] \longrightarrow [/tex] 5 - b = 2t

5 - b = 2t is equivalent to 2t = 5 - b:

[tex] \longrightarrow [/tex] 2t = 5 - b

Divide both sides by 2:

[tex] \longrightarrow [/tex] [tex] \sf \dfrac{2t}{2} = \dfrac{5 - b}{2} [/tex]

Quadrilateral W X Y Z is shown. Diagonals are drawn from point W to point Y and from point Z to point X and intersect at point C. Line segments Z C and C X are congruent. The length of W C is 2 x + 5 and the length of C Y is 3 x + 2. In quadrilateral WXYZ, WC = 2x + 5 and CY = 3x + 2. What must x equal for quadrilateral WXYZ to be a parallelogram? x =

Answers

The value of x must be 3, for quadrilateral WXYZ to be a parallelogram

The given parameters are:

[tex]\mathbf{CY = 3x + 2}[/tex]

[tex]\mathbf{WC = 2x + 5}[/tex]

From the question, we understand that:

Segments ZC and CX are congruent

This means that:

Segments WC and CY are congruent

So, we have:

[tex]\mathbf{WC = CY}[/tex]

This gives

[tex]\mathbf{3x +2 = 2x + 5}[/tex]

Collect like terms

[tex]\mathbf{3x + 2x =-2 + 5}[/tex]

[tex]\mathbf{x =3}[/tex]

Hence, the value of x must be 3, for quadrilateral WXYZ to be a parallelogram

A brand new car costs $18,000, this price depreciates at 25% every year, how much would the car be after 12 years? 20 years?

Answers

Answer:

C(12)=$570.18

C(20)=$57.08

Step-by-step explanation:

Exponential Decay Function

The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

[tex]C(t)=C_o\cdot(1-r)^t[/tex]

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The depreciation of goods is often modeled as an exponential function. The new car costs $18,000 and its price depreciates at r=25%= 0.25 every year.

The depreciation model is:

[tex]C(t)=18,000\cdot(1-0.25)^t[/tex]

Operating:

[tex]C(t)=18,000\cdot 0.75^t[/tex]

At t=12 years, the price will be:

[tex]C(12)=18,000\cdot 0.75^{12}[/tex]

C(12)=$570.18

At t=20 years, the price will be:

[tex]C(20)=18,000\cdot 0.75^{20}[/tex]

C(20)=$57.08
