How do I write the equation of the parabola in intercept form

lord [1]

Answer:

The equation of the parabola in intercept form is $y = -\frac{3}{4}\cdot x\cdot (x-4)$ .

Step-by-step explanation:

The equation of the parabola in intercept form is defined by following formula:

$y = a\cdot (x-r_{1})\cdot (x-r_{2})$ (1)

Where:

$x$ - Independent variable.

$y$ - Dependent variable.

$a$ - Vertex constant.

$r_{1}, r_{2}$ - Intercepts of the parabola.

According to the graph, we find that intercepts are 0 and 4, respectively, and a point in the parabola is $(x,y) = (3, 2.25)$ . If we know that $r_{1} = 0$ , $r_{2} = 4$ and $(x,y) = (3, 2.25)$ , then the vertex constant is:

$a = \frac{y}{(x-r_{1})\cdot (x-r_{2})}$

$a = -\frac{3}{4}$

The equation of the parabola in intercept form is $y = -\frac{3}{4}\cdot x\cdot (x-4)$ .

-4 and a y intercept at 3

scoundrel [369]

Answer:

f(x)=-4x+3

Step-by-step explanation:

Assuming you're talking about f(x)=mx+b. b is y intercept. So f(x)=mx+3. You substitute m for -4, as you said, and we get f(x)=-4x+3

Dominic pays 7% interest on his $16,000 college loan and 12% interest on his $12,000 car loan. What average interest rate does h

Naya [18.7K]

The average interest rate is 8.57% paid on the total of $28,000

<h3>What is the percentage?</h3>

The percentage is defined as a ratio expressed as a fraction of 100.

Dominic pays 7% interest on his $16,000 college loan,

And 12% interest on his $12,000 car loan

To determine the average interest rate paid on the total $28,000 he owes

Calculating the total interest amount paid :

⇒ 7% of 16,000 + 12% of 12,000

⇒ (7/100)16,000 + (12/100)12,000

⇒ (0.07)16,000 + (0.12)12,000

⇒ 960 + 1440

⇒ 2400

So the average interest rate paid on the total of $28,000 as

⇒ 2400/28,000 = 0.0857 ≈ 8.57%

Hence, the average interest rate is 8.57% paid on the total of $28,000
