Answer:

Step-by-step explanation:

The rock will hit the surface when its height equals zero.

t^2-8t-10=0

t^2-8t=10

t^2-8t+16=10+16

(t-4)^2=26

t-4=+(26^(1/2))

t=4+(26^(1/2))

t=9.1s

Alex17521 [72]

Answer:

Size 50

Step-by-step explanation:

You should choose the larger sample size.  This is because if you take the mean, it will help to cancel out outliers.  For instance, most people exercise half an hour.  With sample size of 10, there might be one person who doesn't exercise, thus dragging down the mean.  A larger sample size would have a greater ratio of "average" people.

Write the equation of the line through the given points : <br> I need help please
Diano4ka-milaya [45]

Answer:

y=-3x+5

Step-by-step explanation:

The equation for slope is:

Slope=\frac{y_2-y_1}{x_2-x_1}

We can substitute the given coordinates into the equation:

Slope=\frac{3-0}{\frac{2}{3}-\frac{5}{3}}=\frac{3}{\frac{2-5}{3}}=\frac{3}{\frac{-3}{3}}=\frac{3}{-1}=-3

The slope is -3

The equation for a line is:

y=mx+b

m: slope

b: y-intercept

x, y: (x, y) coordinate pair

Now, plug in the slope and one of the (x, y) coordinate pairs to solve for the y-intercept.

y=mx+b\\y=-3x+b\\0=-3(\frac{5}{3})+b\\0=\frac{-15}{3}+b\\0=-5+b\\$Add 5 to both sides\\b=5

Therefore the equation is:

y=-3x+5
