A ball is thrown into the air. The height in feet of the ball can be modeled by the equation h = -16t2 + 20t + 6 where t is the

makkiz [27]

$f(t)=h=-16t^2+20t+6

$

a=-16, b=20, c =6

Δ= $b^2-4ac=20^2-4*(-16)*6=400+384=784$

$\sqrt{Δ}=\sqrt{784}=28$

max:

$p=-\frac{b}{2a}=-\frac{20}{-32}=\frac{20}{32}=\frac{5}{8}$

max heigh: $h=-16(\frac{5}{8})^2+20*\frac{5}{8}+6=-16\frac{25}{64}+\frac{100}{8}+6$

$h=-\frac{25}{4}+\frac{50}{4}+6=\frac{-25+50+24}{4}=\frac{49}{4}$

$h=\frac{49}{4}$ at $t=\frac{5}{8}s$

will fall down at t:

$t=\frac{-20-28}{-32}=\frac{-48}{-32}=\frac{3}{2}=1.5$

$t=1.5s$

Answer:

A: -41/9

Step-by-step explanation:

Substitute the point (4, -5) and slope -1/9 into the equation y = mx + b.

-5 = -1/9(4) + b

-5 = -4/9 + b

Solve for b:

b = -41/9

Our equation: y = -1/9(x) - 41/9

My favorite recipe for lemonade calls for 4 cups of water to 3/4 cups sugar. How

Nikolay [14]

Answer and Step-by-step explanation:

To find the unit rate, divide the 4 cups of water and the $\frac{3}{4}$ cups sugar by 4 to get a unite rate for 1 cut of water.

4 divided by 4 equals 1.

$\frac{3}{4}$ divided by 4 equals $\frac{3}{16}$ .

Now, we multiply $\frac{3}{16}$ by 6.

$\frac{9}{8}$ is how many cups of sugar that needs to be measured for 6 cups of water.
