Answer:
For first part, t= 0.18 sec or 3.4 sec.
For second part, t= 3.7 sec.
Step by step answer:
First part:
Set h(t) = 17and solve for tt.
-16t²+ 58t + 7= 17
-16t² + 58t - 10 = 0
Solve this quadratic equation for t. You should get 2 positive solutions. The lower value is the time to reach 17 on the way up, and the higher value is the time to reach 17 again, on the way down.
Second part:
Set h(t) = 0 and solve the resulting quadratic equation for t. You should get a negative solution (which you can discard), and a positive solution. The latter is your answer.

Answer:
Area= 247 feet²
Volume= 1235 feet³
Step-by-step explanation:
A storage pod has a rectangular floor that measures 19 feet by 13 feet and a flat ceiling that is 5 feet above the floor.
Area of the floor= length*width
Length= 19 feet
Width= 13 feet
Area= 19*13
Area= 247 feet²
Volume of the pod= area*height
Height of the pod= 5 feet
Area= 247 feet²
volume= 247*5
Volume= 1235 feet³
Answer:
x = 21°
Step-by-step explanation:
Triangle = 180°
Angle YXZ = 34°
Angle XZY = (x + 104)°
Angle x = ?
34° + x° + 104° + x° = 180°
138° + 2x° = 180°
2x° = 180° - 138°
2x/2 = 42/2
x = 21°
