Mathematics

1 answer:

Svetach [21]3 years ago

6 0

Answer:

x = 2, x = -3

Step-by-step explanation:

We are given the following quadratic equation and we are to solve it for x:

$x ^ 2 + x - 6 = 0$

We need to find such factors of -6 that when added give a result of 1 and when multiplied, give a product of -6.

$x ^ 2 + x - 6 = 0$

$x ^ 2 - 2x + 3x - 6 = 0$

$x ( x - 2 ) + 3 ( x - 2 ) = 0$

$(x-2) = 0, (x+3)=0$

x = 2, x = -3

If a ball is thrown into the air with a velocity of 42 ft/s, its height (in feet) after t seconds is given by y = 42t − 16t2. Fi

Andru [333]

$\bf y=42t-16t^2\implies \left. \cfrac{dy}{dt}=42-32t \right|_{t=1}\implies 42-32\implies 10$

A function is great to represent the cost per person to attend the school dance. What restrictions would be made to the domain

Cloud [144]

Answer:

(0, ∞)

Step-by-step explanation:

Take a look at "cost per person." This involves dividing the total paid for admission tickets divided by the number of people attending. Obviously this function would not be defined for zero attendees or for partial attendees. Thus, the domain is made up of all integers greater than zero.
