Answer:

To solve this problem, we can use a system of equations.

We know the quadratic expression has the form

$f(t)=at^{2}+bt$

Using points (1,12) and (4,0), we can form the following system to find a and b.

$12=a+b$

$0=16a+4b$

We need to divide the second equation by -4 and sum both equations

$12=a+b\\0=-4a-b$

$12=-3a\\a=\frac{12}{-3}\\ a=-4$

Then, we use this value to find the other variable

$12=a+b\\12=-4+b\\b=12+4\\b=16$

<h3>Therefore, the quadratic function that models the situation is</h3>

$f(t)=-4t^{2} +16t$ or $f(t)=-4t(t-4)$

According to this expression, after 2 seconds, the height is 16 feet.

$f(2)=-4(2)(2-4)=-8(-2)=16$

Find the solution to the system of equations x + y = 9 and x - y = -1.

Galina-37 [17]

Answer:

(4, 5 )

Step-by-step explanation:

x + y = 9 → (1)

x - y = - 1 → (2)

adding the 2 equations term by term will eliminate y

2x + 0 = 8

2x = 8 ( divide both sides by 2 )

x = 4

substitute x = 4 into either of the 2 equations and solve for y

substituting into (1)

4 + y = 9 ( subtract 4 from both sides )

y = 5

solution is (4, 5 )

Three years after paying $2800 in a startup company, you sell for $2200. The total percent return is what?

masha68 [24]

Answer:

The total percentage return is 26.19

Step-by-step explanation:

Given as :

The amount paid for three years = $ 2800

So, Total amount paid for three years = $ 2800 × 3 = $ 8400

The return amount after three years = $ 2200

The time period = 3 years

Let the percentage return = x %

So, According to question

x % of $ 8400 = $ 2200

Or, x % = $\frac{2200}{8400}$

Or, $\frac{x}{100}$ = $\frac{11}{42}$

∴ x = $\frac{11}{42}$ × 100

I.e x = 26.19

Hence The total percentage return is 26.19 Answer
