That is a good question but I'm not sure
Answer:
y=7
Step-by-step explanation:
Slope: 7-7/4-0=0
Point: (0,7)
pt/slope form:
y-7=(0)(x-0)
y=7
Answer:
The y - intercept is (0, 4)
Step-by-step explanation:
The equation x + 4y = 8 is in 'standard form.' Any line parallel to this line has an equation that looks exactly the same EXCEPT for the constant.
So, let's write out x + 4y = 8 and replace the 8 with C.
x + 4y = C
Now take the coordinates of the given point (4, 3) and substitute them into the above equation: 4 + 4(3) = C = 16
Thus, the equation of the line passing through (4, 3) is x + 4y = 16.
To find the y-intercept, set x = 0 and calculate y:
0 + 4y = 16, or y = 4
The y - intercept is (0, 4)
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.
