It's actually one; the point where the line intersects the x-axis (which is the answer). (x = 5)

If the graph intersects the x-axis at two points, then there is two answer.

A new car is purchased for $17,000 and over time its value depreciates by one half every 3 years. What is the value of the car 1

Jet001 [13]

Answer:

The answer is "$238".

Step-by-step explanation:

Current worth $= \$ 17,000$

depreciates by $\frac{1}{2}$ in 3 years.

time= 19 years

depreciates rate=?

Using formula:

$\to \text{Worth= Current worth}(1- \frac{\text{depreciates rate}}{100})^{time}$

$\to A_t=A_0(1-\frac{r}{100})^t$

calculates depreciate value in 3 year $= \frac{1}{2} \times 17,000$

$= 8,500$

so,

$A_t=8,500\\\\A_0=17,000\\\\t=3\ years$

$\to A_t=A_0(1-\frac{r}{100})^t\\\\\to 8,500= 17,000(1-\frac{r}{100})^3\\\\\to \frac{8,500}{17,000}= (1-\frac{r}{100})^3\\\\\to \frac{1}{2}= (1-\frac{r}{100})^3\\\\\to (\frac{1}{2})^{\frac{1}{3}}= (1-\frac{r}{100})\\\\\to 0.793700526 = (1-\frac{r}{100})\\\\\to \frac{r}{100} = (1-0.793700526)\\\\\to \frac{r}{100} = (1-0.8)\\\\\to r= 0.2 \times 100 \\\\\to r= 20 \%$

depreciates rate= 20%

$\to \text{Worth= Current worth}(1- \frac{\text{depreciates rate}}{100})^{time}$

$= \$ 17,000 (1- \frac{20}{100})^{19}\\\\= \$ 17,000 (1-0.2)^{19}\\\\= \$ 17,000 (0.8)^{19}\\\\= \$ 17,000 \times 0.014\\\\= \$ 238$

One of the roots of the equation 2x^2−bx−20=0 is −2.5. Find the other root

Lemur [1.5K]

Answer:

The answer to your question is x = 4

Step-by-step explanation:

2x² - bx - 20 = 0

One root is -2.5

Process

Get the value of the equation when x = -2.5

2(-2.5)² - b(-2.5) - 20 = 0

2(6.25) + 2.5b - 20 = 0

12.5 + 2.5b - 20 = 0

2.5b = 20 - 12.5

2.5b = 7.5

b = 7.5 / 2.5

b = 3

Then

2x² - 3x - 20 = 0

Factor the polynomial

2 x -20 = -40

2x² -8x + 5x - 20 = 0

2x(x - 4) + 5(x - 4) = 0

(x - 4)(2x + 5) = 0

x₁ - 4 = 0 2x₂ + 5 = 0

x₁ = 4 x₂ = -5/2

x₂ = -2.5
