The FitnessGram pacer test is a multistage aerobic capacity test that progressively gets more difficult as it continues. The 20 meter pacer test will begin in 30 seconds. Line up at the start. The running speed starts slowly but gets faster each minute after you hear this signal bodeboop. A single lap should be completed every time you hear this sound. Ding Remember to run in a straight line and run as long as possible. The second time you fail to complete a lap after the sound, your test is over. The test will begin on the word start. On your mark. Get ready!!!! START!!!!
100m runner (don’t mind this i need it to be 20 characters long)
Answer: The answer is: f(x) = 2x^2 + 40x + 200
Explanation:
Given: x is the width of the Artwork
Let W be the Width of the Frame
Let L be the Length of the Frame
Width = x + 10
Length = Width * 2, so by substitution, Length = 2(x + 10)
Area = Width * Length
By substitution:
Area = (x + 10) * 2(x + 10)
f(x) = (x + 10) * (2x + 20)
f(x) = 2x^2 + 20x + 20x + 200
f(x) = 2x^2 + 40x + 200
To test this, if a picture 8" wide is put in this frame, the width would be 8+10 or 18 inches. The length would be twice the width, or 36 inches. The Area is 18 x 36 = 648.
Using the formula:
f(8) = (2 * 8^2) + (40 * 8) + 200
f(8) = (2 * 64) + 320 + 200
f(8) = 128 + 320 + 200
f(8) = 648
The scientists need to measure for forces are magnitude and direction.
<h3>What is Force?</h3>
The force is defined as the external effort applied in the form of push or pull to cause the acceleration of a body.
Mathematically it is expressed as the product of mass and acceleration of an object.
therefore standard expression for the force as per Newton's second law is given as,
F = ma
Here,
m is the mass of the body.
a is the magnitude of the acceleration of the body.
Also, the force is a vector quantity that has significance for its magnitude as well as the direction.
So scientific analysis regarding the force needs its magnitude along with the direction of application.
Thus,The scientists need to measure for forces are magnitude and direction.
