The correct answer is h≈3.6
Formula- Radius and volume
Hope this helps
Answer:
h(t) = 4.68 seconds
Step-by-step explanation:
The function that represents the height of each firework in feet is :
.....(1)
We need to find the time the fireworks take to reach their maximum height. For maximum height,
dh/dt = 0
So,
Put t = 4.68 in equation (1).
So, the fireworks will take 4.68 seconds to their maximum height.
Answer:
D. 5.32 cubic units
Step-by-step explanation:
Volume of a cone = ⅓πr²h
Radius (r) = 1.52 units
Height (h) = 2.2 units
π = 3.14
Substitute
Volume = ⅓*3.14*1.52²*2.2
Volume = 5.32 cubic units

PLEASE RATE AS THE BRAINLIEST ANSWER! THANK YOU! :)
Let's start with y = 4x + b (since 4 is the slope);
We need to find what number should be put instead of b;
Then, let's see what needs to be done;
Plug in the y and x values from the coordinate (22,12) into y=4x+b;
12 = 4(22) + b
Solve;
12 = 88 + b
12 - 88 = b
b = -76
Remember the equation y = 4x + b? Put the -76 instead of b:
y = 4x + -76
or: y = 4x - 76
That is the equation.
To make it standard form, put x and y both in the left side, with x first then y:
-4x + y = -76
