Answer: B. t=2

Step-by-step explanation:

If we implement t=2 into the function h=32(2)-16(2)^2 we get the height of 0 (Ground level).

Solve for h by simplifying both sides of the equation, then isolating the variable.

Hope this helps! :)

Which equation describes this line?
yawa3891 [41]

Answer:

The equation of line with given points is  y - 4 = 3 ( x + 2 ) .

Step-by-step explanation:

Given as :

The points of line are ( 1 , 13 )   and    ( - 2 , 4 )

The point slope intercept equation of line is

y - y_1 = m ( x -  x_1 )

Where m is the slope of line

So , Slope , m = \frac{y_2 - y_1}{x_2 - x_1}

Or, m =  \frac{4 - 13}{ - 2 - 1}

Or, m =  \frac{ - 9}{ - 3}

∴    m = 3

Now The equation of line is

y - y_1 = m ( x -  x_1 )

Or. y - 13 = 3 ( x -  1 )

Or, y - 13 = 3 x - 3

Or, y = 3 x - 3 + 13

∴   y = 3 x + 10

I.e y - 4 = 3 x + 6

Or, y - 4 = 3 ( x + 2 )

Hence The equation of line with given points is  y - 4 = 3 ( x + 2 ) . Answer

Perform the indicated operation. f(n)=n-3 g(n)=n-2 find (f+g)(6)
Grace [21]

Answer:

7

Step-by-step explanation:

(f + g)(n) = f(n) + g(n) = n - 3 + n - 2 = 2n - 5 , thus

(f + g)(6) = 2(6) - 5 = 12 - 5 = 7
