Average rate of change of polynomials
1 answer:
Answer:
1
Step-by-step explanation:
g(t)= -(t -1 )² +5
1. Calculate the values of g(-4) and g(5)
g(-4) = -(-4 - 1)² + 5 = -(-5)² + 5 = -25 + 5 = -20
g(5) = -( 5 - 1)² + 5 = - (4)² + 5 = -16 + 5 = -11
2. Calculate the average rate of change
Rate of change = (y₂ - y₁)/(x₂-x₁) = [-11 -(-20)]/[5 - (-4)] = (-11+ 20)/(5 + 4) = 9/9 = 1
The average rate of change is 1.
In the figure below, the red curve represents the function g(t), while the black dashed line represents the average rate of change over the interval [-4,5].

x = 52
let x be the angle then (180 - x ) represents one half of the supplement of the angle and
2( 90 - x ) - 12 represents 12 less than twice the complement of the angle
equating these 2 expressions
(180 - x ) = 2(90 - x ) -12
distribute brackets on both sides
90 - x = 180 - 2x - 12 = 168 - 2x
add 2x to both sides
90 + x = 168 → ( subtract 90 from both sides )
x = 78
multiply both sides by 2 and divide by 3
x = 52
