Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 5x + 1
x = 2
x = 3
<u>Step 2: Evaluate</u>
x = 2
- Substitute: f(2) = 5(2) + 1
- Multiply: f(2) = 10 + 1
- Add: f(2) = 11
x = 3
- Substitute: f(3) = 5(3) + 1
- Multiply: f(3) = 15 + 1
- Add: f(3) = 16
Answer:
x = 10
Step-by-step explanation:
OA = OD ( both radii of the circle )
OD = OB + BD = x + 16
OB is at right angles to OB ( line from centre to midpoint of chord is right )
Using Pythagoras' identity in right triangle ABO
OA² = OB² + AB² , that is
(x + 16)² = x² + 24²
x² + 32x + 256 = x² + 576 ( subtract x² from both sides )
32x + 256 = 576 ( subtract 256 from both sides )
32x = 320 ( divide both sides by 32 )
x = 10
Answer:
a.) 48m
b.) 158m
m<B.) 73 degrees
Step-by-step explanation:
No because you still don't know what the value of x is.
The area would be length times width so the answer is 648 squared inches!
