Answer:
The inequality correctly matches the graph is -2 < x < 4 ⇒ B
Step-by-step explanation:
From the given figure
∵ There is a segment drawn from -2 to 4
∴ The starting point of the inequality is -2
∴ The ending point of the inequality is 4
∵ The endpoints of the segments are white circles (not shaded)
→ That means the signs of inequality without sign =
∴ The values of x are between -2 and 4
∴ The inequality is -2 < x < 4
∴ The inequality correctly matches the graph is -2 < x < 4

Answer:
max height = 7.5 ft
1.3 ft far
Please check below for the detailed answer
Step-by-step explanation:
<u>Given: </u>
f(x) = −0.3x^2 + 2.1x + 7
a) To obtain the maximum height , find f'(x)
f'(x) = - 0.6x + 0.8 = 0
=> x = 0.8 / 0.6 = 1.33 feet
So f(x) is maximum at a horizontal distance of 1.33 ft
To find the max height , find f(1.33)
f(x) = −0.3x^2 + 2.1x + 7, plug in 1.33 for x
=> f(1.33) = −0.3(1.77) + 0.8(1.33) + 7 = 7.5 ft
So the answer is
Maximum height = 7.5 ft , and 1.3 ft far from where it was thrown.
Answer:
The sports car, because it has less mass and therefore less inertia
Step-by-step explanation:
When an object has less inertia it is easier to be put into and out of motion, and a sports car would obviously weigh less than a van.
