Answer:
I only
Step-by-step explanation:
given h = - at² + bt + c
the vertex = -
Thus altering a or b effects the position of the vertex
and the maximum value is the value of the vertex
Altering c effects the h-intercept only
Point M is will be plotted between L and N on the number line.

Answer:
Height of Tower = 41.8901 ft
Base to Ground Wire = 94.0905 ft
Step-by-step explanation:
So you want to find the opposing side of the angle, as well as the distance from the base to where the wire is attached to the ground. You would need to use CAH to find the ground, and SOH to find the height. To find the height or opposite, take the Sine of 24°, 0.4067, and times it by your hypoteneuse 103 to get an exact height of 41.8901 ft. Next, use the Cosine of 24°, 0.9135, and times that by your hypoteneuse 103 to get 94.0905 ft.
Here are the equations:
sin(24)=
cos(24)=
Answer:
2.4 years
Step-by-step explanation:
We can write two equations for each Type and equate and solve for unknown variable.
First, we need to make the initial height (in ft) to inches.
<u>Type A:</u>
3 feet = 3 * 12 = 36 inches
<u>Type B:</u>
4 feet = 4 * 12 = 48 inches
Let "t" be the number of years
For Type A, the equation would be:
36 + 15t [36 inches already and 15 inches per year]
For Type B, the equation would be:
48 + 10t [48 inches and 10 inches per year]
Now we equate and solve for "t", the time when both are same height:
Hence, after 2.4 years, both trees' heights would be same
