Answer: 175 minutes where used
Step-by-step explanation:
Refer to the diagram shown below.
h = the height of the cliff.
d = the distance of the landing spot from the base of the cliff.
Assume that air resistance may be neglected, and g = 9.8 m/s².
The horizontal distance traveled in 2 seconds is
d = (1.8 m/s)*(2 s) = 3.6 m
The initial vertical velocity component is zero.
Therefore the vertical height traveled before landing on the water obeys the equation
h = (1/2)*(9.8 m/s²)*(2 s)² = 19.6 m
Answers:
The height of the cliff is 19.6 m
The distance of the landing spot from the base of the cliff is 3.6 m
Answer:
y = 2x + 4
Step-by-step explanation:
- Form the equation of how to get the gradient of a line.
- Substitute the values you have to the equation and solve it to form the equation y = 2x + 4.
19/2
If you don’t want an improper fraction then nothing further can be done so the answer would stay the same (8 3/2)
The Hypotenuse Angle Theorem states that if one acute angle and the hypotenuse of the two right angled triangles are congruent then the triangles are congruent.
ADC is congruent to triangle CBA given that ∠D and ∠B are right angles and DC is parallel to AB.
Given: ∠D and ∠B are right angles
DC || AB
Prove: △ADC ≅ △CBA
STATEMENT REASON
1.∠D and ∠B are right angles 1. Given
2. ∠1=∠ 2 2. If lines are parallel, then alternate
Interior angles are equal
3. AC ≅ AC 3. Common to both △s
4. △ADC ≅ △CBA 4. Hypotenuse Angle Theorem
