You could set up a proportion
86/x = 98/100
Then solve for x, I'll do it by cross-multiplying.
86 times 100 divided by 98 = 87.755102
87-88 problems
The circumference is usually three times as much as the diameter
Is there anything else on the paper that can help me with that? like any questions at the top?
Step-by-step explanation:
y = -2x² + 4x + 1
Complete the square.
y = -2 (x² − 2x) + 1
y = -2 (x² − 2x + 1) + 1 − (-2)(1)
y = -2 (x − 1)² + 3
The vertex is (1, 3). The leading coefficient is negative, so the vertex is a maximum.
