Answer:
Step-by-step explanation:
100 = -16t^2 + 92t
16t^2-92t + 100 = 0
4t^2 - 23t + 25 = 0
t = [23 ±√(23^2-4(4)(25))]/[2(8)] ≈ 1.5, 4.3
The rocket has altitude of 100 ft at 1.5 sec and 4.3 sec.
:::::
0 = 16t^2-92t = t(16t-92)
t = 0, 5.75
Rocket is in the air for 5.75 seconds
Answer:
18.6 units
Step-by-step explanation:
A rectangle is a four sided shape with 4 perpendicular angles. It has two pairs of parallel sides which are equal in distance: width and length. A diagonal can be drawn between opposite corners that splits the triangle into two equal right triangles. The distance of this diagonal is found using the Pythagorean Theorem a² + b² = c². In the rectangle a = 11 and b = 15. Substitute these values and simplify using a square root operation.
11² + 15² = c²
121 + 225 = c²
346 = c²
√346 = c
18.6= c
