Answer:
Step-by-step explanation:
Given
--- acceleration
--- final velocity
--- initial velocity (it is 0, because the car starts from rest)
Required
Determine the time taken
This will be solved using Newton's first equation of motion:
Substitute values for v, u and a
Make t the subject
<em>Hence, the time taken is approximately 5.2 seconds</em>
Answer: The missing side is 5 units.
Step-by-step explanation:
Pythagorean Theorem states that a^2+b^2=c^2. Let the hypotenuse be x.
![4^2+3^2=x^2\\16+9=x^2\\25=x^2\\\sqrt{25}=\sqrt{x^2}\\\left[\begin{array}{c}x=5\end{array}\right]](https://tex.z-dn.net/?f=4%5E2%2B3%5E2%3Dx%5E2%5C%5C16%2B9%3Dx%5E2%5C%5C25%3Dx%5E2%5C%5C%5Csqrt%7B25%7D%3D%5Csqrt%7Bx%5E2%7D%5C%5C%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dx%3D5%5Cend%7Barray%7D%5Cright%5D)
Hope it helps <3
The expression is the same but know explain in the same way
Work out ys and shade the reigon
Answer:
x≤50
Step-by-step explanation:
100-3x≥-50
subtracting 100 at both side on inequality
-100+100-3x≥--50-100
-3x≥-150
Dividing both sides by 3
-3x/3≥-150/3
-x≥--50
Adding 50 on both sides
-x+50≥-50+50
-x+50≥0
Adding x on both sides
-x+x+50≥0+x
50≥x
so,
x≤50
