juin [17]

Answer:

$unit\ rate=22\ frames\ per\ second$

Step-by-step explanation:

we know that

To find the unit rate , divide the total frames by the total seconds

x ----> the total frames displayed by the video game

y ----> the total seconds

$unit\ rate=\frac{x}{y}$

we have

$x=132\ frames\\y=6\ seconds$

substitute the values

$unit\ rate=\frac{132}{6}=22\ frames\ per\ second$

Write a quadratic equation whose roots are -4 and one and who's leading coefficient is five

Alex

Step-by-step explanation:

- 4 and 1 are roots.

Therefore, (x + 4) & (x - 1) are factors and 5 is leading coefficient.

Therefore, required quadratic equation is:

$5 (x + 4) (x - 1) \\ = 5( {x}^{2} - x + 4x - 4) \\ = 5( {x}^{2} + 3x - 4) \\ = 5 {x}^{2} + 15x - 20$
