Step-by-step explanation:
<u>Step 1: Add 8 to both sides</u>
<u>Step 2: Multiply both sides by -4</u>
Answer:
Answer:
The ratio of the drag coefficients is approximately 0.0002
Step-by-step explanation:
The given Reynolds number of the model = The Reynolds number of the prototype
The drag coefficient of the model, = The drag coefficient of the prototype,
The medium of the test for the model, = The medium of the test for the prototype,
The drag force is given as follows;
We have;
Therefore;
= (1/17)^3 ≈ 0.0002
The ratio of the drag coefficients ≈ 0.0002.
Answer:
OPTION B - 2
Step-by-step explanation:
What is the upper limit for the zeros of the function P(x) = 4x^4 + 8x^3 - 7x^2 - 21x - 9. Ans: 2 is an upper limit. Use synthetic division. and the remainder are all positive, 2 is an upper limit.
Answer:
y=2x+13
Step-by-step explanation:
find gradient which is -2
-7-3/0--5=-10/5 =-2
y-3 =-2. (cross multiply)
x--5
y-3=2x+10
y=2x+13
