Answer:
12.9 hours.
Step-by-step explanation:
First, do 2.15 hours multiplied by 2, for each day. Then, multiply 4.30 by the 3 for 3 weeks.
A
h(x)=6x^2+1
B
f(t)=-16t^2+48t
Before it hit the ground eqn would be
-16t^2+48t=0
16t^2=48t
t=3
3 seconds in the air before it hit the ground
Answer:
100
Step-by-step explanation:
Since, line a is parallel to line t ( from diagram ).
x - 30 and 70 are alternate interior angles.
Reason : -
Alternate interior angles are equal when two lines are parallel and cut by a transversal line.
x - 30 = 70
x = 70 + 30
x = 100
It’s the first one because the parabola is open
Answer:
t = 6√3 mm
Step-by-step explanation:
The angles of the triangle are 30°, 60°, and 90°. That's lucky for you, because the sides of a 30°-60°-90° triangle are always in the ratio 1:√3:2
The side opposite the 90° angle is 12 mm, so the side opposite the 30° angle is 12/2 = 6 mm
t = side opposite the 60° angle = 6√3 mm.
