Both questions please ❤️
Answer:
1.
2. x=108, y=180
Step-by-step explanation:
The height of the right triangle drawn to the hypotenuse is the geometric mean of two segments of the hypotenuse (two legs' projections)
1. Use this property, so
Consider right triangle BCD. By the Pythagorean theorem,
2. Consider right triangleGM*. By the Pythagorean theorem,
Use this property to find x:
Consider right triangle GMCup. By the Pythagorean theorem,
the ball will take 6.5 seconds to hit the ground
The question from the student is about time airborne for a volleyball hit upwards with an initial velocity. A physics equation of motion is utilized to solve it by inserting the values and extracting time.
The subject of the question is physics, specifically the subtopic of kinematics in terms of upward motion. The problem can be solved by using the equation of motion: `y = y0 + v0 * t - 0.5 * g * t²`, where y0 is the initial height, v0 is initial velocity, g is the acceleration due to gravity and t is the time taken. In this situation:
Set y (the final position) to 0 (ground level), and solve for t (time taken):
0 = 1m + (13 m/s) * t - 0.5 * (9.8 m/s²) * t²
Solving this quadratic equation, we get two solutions as the time cannot be negative for this context, so choose the positive value as the time taken for the ball to hit the ground. This will give the duration the volleyball remains in the air after being hit by Martina.

B) 7
C) 8
D) 9
The question is an illustration of divisions.
Cindy needs to buy (c) 8 packs
The given parameters are:
The number of packs is calculated by dividing the total number of invitation by the number of invitations in each pack.
So, we have:
Cindy needs 7.5 packs.
Since the packs cannot be split, Cindy must buy the closest number of packs greater than 7.5
So, we have:
Hence, Cindy needs to buy (c) 8 packs
