Answer:

The graph of the equation h=-16t^2+80 is shown in the figure attached.

The y-intercept is obtained replacing t = 0 in the equation, as follows

h=-16(0)^2+80 = 80

The x-intercepts are obtained replacing h = 0 in the equation, as follows

0=-16t^2+80

16t^2 = 80

t^2 = 80/16

t = √5

t ≈ -2.236 or  t ≈ 2.236

With this 3 points, (0, 80) (-2.236, 0) (2.236, 0)  the curve of a quadratic equation is defined.

If you have 2 different slopes what is true about the slopes
Anna007 [38]

Answer:

Step-by-step explanation:

If two lines have different slopes, they cannot be the same line. If they share a y-intercept, that means they cross the y -axis at the same y value.  If they share an x value and corresponding y value, they intersect at that point, in this case their y-intercept.

Hope this helped!!

If it takes 8 inches of ribbon to make a bow,how many bows can be made from 3 feet of ribbon (1 foot = 12 inches)? Will any ribb
Aloiza [94]

First, find out how much ribbon there is.

3 x 12 = 36

Now, see how many times you can divde that by 8.

36 can only be divided by 8 four times, and there would be 4 inches of ribbon left.

So, you would be able to make 4 bows, with 4 inches of ribbon remaining.

boyakko [2]

Answer:

7 + 42i.

Step-by-step explanation:

u v = 7i(6 - i)

=  42i - 7i^2    But i^2 = -1 so:

=  42i - 7(-1)

=     7 + 42i.
