Answer:
2) -141 hits/da
Step-by-step explanation:
Calculate the values of h(2) and h(4)
h(2) = 2170(0.92)² = 2170 × 0.8464 = 1837
h(4) = 2170(0.92)⁴ = 2170 × 0.7164 = 1555
Calculate the average rate of change
Rate of change = (y₂ - y₁)/(x₂-x₁) = (1555 -1837)/(4 - 2) = -282/2 = -141 hits/da
The average rate of change is -141 hits/da.
In the figure below, the red curve represents the function h(d), while the green dashed line represents the average rate of change over the interval 2 ≤ d ≤4.
Answer:
(-7,2)
Step-by-step explanation:
The point (7,-2) when reflected across the x-axis becomes (7, 2). When it is reflected across the y-axis it becomes (-7,2). You can find this because when a point is reflected across the x-axis, its y-coordinate changes its sign. The same is true when reflected across the y-axis. It's x coordinate changes its sign.
A double reflection across both axis changes the sign of each coordinate.
Answer:
9 cars
Step-by-step explanation:
8 minutes = 3 cars
8 minutes x 3=24 minutes
3 cars x 3 = 9 cars
Answer:
They are actually 53.9 miles away.
Step-by-step explanation:
1 in = 15.4 mi
Set up an equation:
Variable x = number of miles
1/15.4 = 3.5/x
Cross multiply:
1 × x = 15.4 × 3.5
x = 53.9
