Step-by-step explanation:
65 - 2 × 7 + 9 ÷ 3
65 - 14 + 3
51 + 3 = 54
Option A is the correct answer
Answer: 1.4 seconds
<u>Step-by-step explanation:</u>
The equation is: h(t) = at² + v₀t + h₀ where
- a is the acceleration (in this case it is gravity)
- v₀ is the initial velocity
- h₀ is the initial height
Given:
- a = -9.81 (if it wasn't given in your textbook, you can look it up)
- v₀ = 12
- h₀ = 3
Since we are trying to find out when it lands on the ground, h(t) = 0
EQUATION: 0 = 9.81t² + 12t + 3
Use the quadratic equation to find the x-intercepts
a=-9.81, b=12, c=3

Note: Negative time (-0.2) is not valid
Answer:
38.47 m2
Step-by-step explanation:
Area = 3.5 x 3.5 x 3.14
Area = 12.25 x 3.14
Area = 38.465 --> 38.47m2
Hope that helps!
The given equation is:

We have to find, which of the given set of parametric equations given in the options, result in the above equation:
The correct answer would be option A.
The equations in option A are:

From first equation we can see that 5t is equal to x. Using the value of 5th in second equation, we get the equation as:
Therefore, the correct answer is option A
C because if you divide the angle minus the feet you get 120
