Answer:
20 feet
Step-by-step explanation:
Remember the Pythagorean theorem,
x^2 + y^2 = n^2
in this case
x= 16
y = 12
so substitute back into the equation
16^2 + 12^2 = n^2
256 + 144 = n^2
400 = n^2
sqrt ( 400) = n
20 = n
First, draw a diagram of a kite with sides GHIJ. The sides GH, HI, IJ, and JG are the sides. The diagonals can be determined by connecting the opposite sides. J and H, G and I. Therefore, the diagonals for the Kite GHIJ is JH and GI.
Answer:
x =0 and x = 4
Step-by-step explanation:
It is a quadratic function and hence will have two roots. It cuts graph at 2 points( x - axis ). Hence has two roots.
Pattie runs at 5 ft/sec
She has got a head start of 15 feet.
So after 1 second, Pattie runs = (5+15) ft
<span>
= 20 </span>
ft
After 2 second Pattie runs = (20+5)ft
= 25 ft
After 3 second Pattie runs = (25+5) ft
= 30 ft
After 4 seconds Pattie runs = (30+5) ft
= 35 ft
After 5 seconds Pattie runs = (35+5) ft
= 40 ft
After 6 seconds Pattie runs = (40+5) ft
= 45 ft
Now Keith runs at 8 ft/sec
After 1 second Keith runs = 8 ft
After 2 second Keith runs = (8+8) ft
= 16 ft
After 3 second Keith runs = (16+8) ft
= 24 ft
After 4 second Keith runs = (24+8) ft
= 32 ft
After 5 second Keith runs = (32+8) ft
= 40 ft
After 6 second Keith runs = (40+8) ft
= 48 ft
So Pattie will stay ahead of Keith upto 4 seconds. In the 5th second Pattie and Keith will be level and in the 6th second Pattie will be overtaken by Keith.
