This can be solved in two ways: With heavy tools or with just algebra.
What is your level? Have you studied calculus?
With pure algebra:
We need to find the maximum of the function <span>h = −16t^2 + 36t + 5
Lets take out -1 for simplicity:
</span><span>h = −(16t2 - 36t - 5)
For now lets just work with this: </span>16t^2 - 36t - 5
16t^2=(4t)^2
(4t-x)^2= 16t^2-2*4xt+x^2
we have -36t so x should be 4.5 as 2*4*4.5=36
Lets see what we have now:
16t^2 - 36t - 5= (4t-4.5)^2 is this true? No but close
(4t-4.5)^2= 16t^2- 2*4*4.5t +4.5^2= 16t^2-36t+20.25
16t^2 - 36t - 5 and 16t^2-36t+20.25 nearl the same just take away 25.25 from the right hand side
Getting long, just stay with me:
16t^2 - 36t - 5= (4t-4.5)^2 - 25.25
h= -{(4t-4.5)^2 -25.25}
h=-(4t-4.5)^2 + 25.25
We want to find the maximum of this function. -(4t-4.5)^2 this bit is always negative or 0, so it maximum is when it is 0. Solve: 4t-4.5=0
t=1,125
Answer:
684 mm squared
Step-by-step explanation:
Very simple. It's 18mm multiplied by 38 mm.
18 mm * 38 mm = 684 mm2
The correct option is a. 550 dm.
The 0.55 hectometers expressed in decimeters are 550 dm.
<h3>What is unit conversion?</h3>
Unit conversion is a multi-step process that involves multiplying or dividing by a numerical factor and, more specifically, a conversion factor.
- The process may also necessitate selecting the appropriate amount of significant digits and rounding.
- Different conversion units are employed to measure various parameters.
- Measuring Temperature
- Measuring Length
- Measuring Capacity
- Measuring Weight
- Conversion of units is defined as the process of converting between different units & measurements of a given quantity using multiplication or division.
- Conversion is the method of changing the amount of one form in terms of mathematics, such as inches to millimeters or liters to gallons.
- Units are used in the measurement of length, weight, capacity, temperature, and speed.

Answer:
y = x + 2
Step-by-step explanation:
Point (0, 2) :
y = x + 2
2 = 0 + 2
2 = 2
Point (4, 6) :
y = x + 2
6 = 4 + 2
6 = 6
