The ball is dropped from a building and the quadratic function which models the ball`s height is:
h ( t ) = - 16.1 t² + 150
We can find the initial height if we calculate h ( 0 ), or the height for : t = 0 sec.
h ( 0 ) = -16.1 · 0² + 150 = 0 + 150 = 150 ft
Answer:
The ball was dropped from 150 feet.
data is not provided. what type of degrees? and which country?
1) Equation of the line
Slope, m = [-2 -1]/[0 - 2] = -3 / -2 = 3/2y-intercept, b = -2
y = 3x/2 - 2
2) InequalityThe points over the line have y-coordinate greaetr than the value of the line, then
y ≥ 3x/2 - 2
2y ≥ 3x - 4
3x - 2y ≤ 4
3) Answer: 3x - 2y less than or equal to 4.
Answer:
The decimal 0.345 expressed as a fraction is 69200 .
Im guessing 21 and 72 are the side lengths for the triangle?
Alright, so since it's a right triangle you can use the Pythagorean theorem or a^2+b^2=c^2
Since i cant see the picture, im going to use some general math <span>so i</span> can figure out if those two sides are the legs or if one of them is the hypotenuse
Alright
so im guessing the side we're trying to find is the hypotenuse
21^2+72^2=c^2
441+5184=c^2
5625=c^2
<span>√5625=c</span>
75=c
The answer is 75, hope i helped!
