Answer:
When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.
0 = -(x-2)^2 + 16
(x-2)^2 = 16
x-2 = 16
x-2 = 4
x = 6
This means the ball will hit the ground 6 seconds after Amir threw it.
Step-by-step explanation:
(5/3)*(7/3) = 35*(1/3)²
The area is 35 square units.
Answer:
it's pretty simple y × 50
Answer:
22
Step-by-step explanation:
The centroid divides a median in two parts that have this ratio = 1/3 and 2/3
In particular the part between the vertex and the centroid is 2/3 of the median.
So we have:
XN = (33 * 2)/3 = 22
Answer:
m∠x = 119°
m∠y = 61°
m∠z = 119°
Step-by-step explanation:
Angle x:
- m∠x = 180° - 61° (sum of angles in a straight line)
- m∠x = 119°
Angle y:
- m∠y = 61° (Alternate interior angles)
Angle z:
- m∠z = 119° (Sum of angles in a line, corresponding angles)
