Answer:

It would take the projectile 4 seconds

T = 4

Step-by-step explanation:

g = 32 feets/ seconds (s)

s = 128 feet

t = ?

g = <u>s</u>

g = s t

32 = <u>12</u><u>8</u>

t

t = <u>12</u><u>8</u>

32

t = 4 seconds

27? i cant figure out her mistake can anyone help ?
expeople1 [14]
The mess up occurs in one of the first things she says. She first claims that 7^2 +25^2 = 24^2
Wait a minute... slow your roll there.
25 is the hypotenuse, or the longest side of the triangle AND opposite the right angle (but we aren't supposed to know that yet).
The Pythagorean Theorem holds that a^2 + b^2 = c^2, where a & b are the legs of the triangle & c is the hypotenuse. So, she got the formatting correctly, but she switched 24 & 25.
Hope this helps!
