Write a quadratic equation in standard form that has roots of -12 and 2
Vinvika [58]

A quadratic with roots at 8 and 5 is f(x) = x^2 + 10x - 24

In order to find an equation given roots you can create statements that equal 0 in order to create parenthesis. For instance we know x = 8 at one point. So, we can solve that to equal 0.

x = -12 ----> add 8 from both sides

x + 12 = 0

We can do the same for the other zero.

x = 2 ----> subtract from both sides

x - 2 = 0

Now that we have both of these, we can multiply these two things together. This will give us the function we need.

f(x) = (x + 12)(x - 2)

f(x) = x^2 + 12x - 2x - 24

f(x) = x^2 + 10x - 24

<h2><u>Answer:</u></h2>

'?' is <u>88°.</u>

<h2><u>Step-by-step explanation:</u></h2>
  • First, we work out the final angle of the left triangle, which has a total of 180°. To do this we take 40° and 66° from 180°, giving us <u>72°</u>
  • Because there is a straight line along the bottom (which will total 180°), we take both 72° and 56° from 180°, giving us <u>52°</u>, which is the bottom left angle of the right triangle.
  • Finally, to work out '?', we take 52° and 40° from 180° to get our final answer of <u>88°.</u>

A toy rocket launched into the air has a height ( h feet) at given time ( t seconds) as h= -16^2+160t until it hits the ground.
Gennadij [26K]

Answer:

t = \frac{53}{32}

Step-by-step explanation:

h=\:-16^2+160t

9=\:-16^2+160t      substitute

-16^2+160t=9

-256+160t=9

-256+160t+256=9+256

160t=265

\frac{160t}{160}=\frac{265}{160}

t=\frac{53}{32}

At  \frac{53}{32}  seconds it is at a height of 9 ft.
