Answer: The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8
What is an equation?
An equation is an expression that shows the relationship between two or more variables and numbers.
A quarterback throws a football toward a receiver from a height of 6 ft. The initial vertical velocity of the ball is 14 ft/s. At the same time that the ball is thrown, the receiver raises his hands to a height of 8 ft and jumps up with an initial vertical velocity of 10 ft/s.
The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8
Answer:
Step-by-step explanation:
So if you expand out the two binomials (k-2)(k+1), you'll get: 
. which simplifies to: 
. Multiplying this by the k gives you: 
. As you can see the degree is odd, this means that this polynomial will have two opposite end behaviors. And as you can see the leading coefficient is positive, meaning that this function will go towards positive infinity as k goes towards positive infinity. Also we if look at the original equation given, it's in factored form, with the zeroes as k=0, k=2, and k=-1. So given this we can draw a simple graph to see when the value of the equation is negative. If you look at the graph I drew you'll see that it's negative from (-infinity, -1) and then negative from (0, 2)
Answer:
Usually written y=kx, where k is the factor of proportionality.
Step-by-step explanation:
We have that
points (−1, 0) and (0, −3)
step 1
find the slope m
m=(y2-y1)/(x2-x1)-------> m=(-3-0)/(0+1)--------> m=-3
step 2
find yhe equation of the line with m and the point (0, −3)
y-y1=m*(x-x1)-------> y+3=-3*(x-0)-----> y=-3x-3-----> y+3x=-3
the answer is the option
<span>C) 3x + y = −3</span>
see the attached figure
When simplifying you want to combine like terms so 14x²-12x² will equal 2x², now we move on to X, where 3x+11x will result in 14x, last we add up numbers without X so 4-3 is 1.
The Answer will end up being 2x²+14x+1 (B)
