Answer:
Time it took for the walker to land on net = 1.75 seconds
Step-by-step explanation:
Given:
Height above the ring as a function of time is give as:
Height of the tightrope walker after he falls = 11 feet
Plugging the height in order to find the time it took for the walker to land on net.
Adding to both sides.
Subtracting both sides by 11.
Dividing both sides by 16.
Taking square root both sides.
Since time is always positive
∴
∴ Time it took for the walker to land on net = 1.75 seconds
Y=2x
so what you do is sub 2x for y in the top equation
x^2+(2x)^2=5
x^2+4x^2=5
5x^2=5
divide both sides by 5
x^2=1
sqrt both sides
x=1 or -1
sub back
y=2x
y=2(-1)
y=-2
y=2(1)
y=2
the solutions are (1,2) and (-1,-2)
Answer:
-10.49.
Step-by-step explanation:
Using order of operations PEMDAS:
4(-8+4.5)/ 6.25 + (-8.25)
= 4 * -3.5 / 6.25 - 8.25
= -14/6.25 - 8.25
= -2.24 - 8.25
= -10.49.
