Inorder to find the height, you miust plug in 0.05s for all times (t)
h(f) = -490t^2 + 75t + 12
h(f) = -490 • 0.05^2 + 75 • 0.05 + 12
Next follow PEMDAS from left to right.
(MD reversible, AS reversible)
(parentheses, exponents, multiply, divide, add, subtract)
parentheses~ nothing to simplify with parentheses
exponents~ h(f) = -490 • 0.0025 + 75 • 0.05 +12
multiply~ h(f) = -1.225 + 3.75 +12
divide~ nothing to simplify with division
add~ h(f) = 14.525
subtract~ nothing to simplify with subtraction
DON'T FORGET UNITS!
Answer: h(f) = 14.525 cm
Answer:
w = 1.5
Step-by-step explanation:
22(w + 2) = 77
22w + 44 = 77
22w = 77 - 44
22w = 33
22w/22 = 33/22
w = 1.5
