Answer:
The recoil velocity of the gun is and is pointing in opposite direction to the velocity of the bullet.
Step-by-step explanation:
Use conservation of linear momentum, which states that the momentum of the bullet (product of the bullet's mass times its speed) should equal in absolute value the momentum of the recoiling gun (its mass times its recoil velocity).
We also write the mass of the bullet in the same units as the mass of the gun (for example kilograms). Mass of the bullet = 0.010 kg
In mathematical terms, we have:
Answer:
see below
Step-by-step explanation:
Because the area of the square is 36 its side is 6 meaning the circle has a diameter of 6. This means that its radius is 3 so its area is 3² * π = 9π.
Answer:
15 inches
Step-by-step explanation:
We can solve this problem using the Pythagorean theorem. The formula is:
where 'c' is the <u>hypotenuse</u> (the longest side) and 'a' and 'b' are the <u>legs</u> (the other sides).
First, <u>draw a diagram</u> for the problem. (See the photo attached below)
We know the other leg is 8 and the hypotenuse is 17. 'a' is the missing side.
a = ?
b = 8
c = 17
<u>Substitute the values into the equation</u>.
<u>Rearrange to isolate 'a'</u>
Square root both sides
Square each number
Subtract under the root
Find the square root
Final answer
Therefore, the TV is 15 inches tall.
Given:
The function is
The binomial is a factor of f(x).
To find:
The value of .
Solution:
If is a factor of f(x), then .
It is given that, is a factor of f(x), then .
We have,
Substituting x=4, we get
Now,
Therefore, the value of a is 5.
