Step-by-step explanation:
<u>Step 1: Define</u>
y = 5x + 1
x = 3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: y = 5(3) + 1
- Multiply: y = 15 + 1
- Add: y = 16
Answer:
18/5 = 3.6 (note that 3/2 = 1.5 )
the actual division is 3.387
Step-by-step explanation:
Put the given information into the formula and solve for the variable of interest.
.. V = π*r^2*h
.. 24 = π*(h/3)^2*h
.. 24 = π/9*h^3
.. 9*24/π = h^3
.. ∛(216/π) = h
.. h = (6/π)√(π^2) ≈ 4.097 . . . . units
The height of the cylinder is about 4.097 units.
Answer:
Diameter = 19.33
Step-by-step explanation:
Imaging a radius line from O to the endpoints of the 7. call this line R.
Label the part of the vertical line from O to the 90 degree intersection y.
Now you have a right triangle.
Using the Pythagorean theorem:
R² = 7² + y²
also
y = R - 3
substitute for y:
R² = 49 + (R-3)²
R² = 49 + R² - 6R + 9
simplify:
0 = 58 - 6R
6R = 58
R = 9.6667
Diameter = 2(9.6667) = 19.33
