Answer:
The answer to the question is 1
Answer:
The value of 
is 
.
Step-by-step explanation:
The given equation is
We need to find the value of .
Differentiate with respect to t.
![[\because \frac{d}{dx}x^n=nx^{n-1},\frac{d}{dx}C=0]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Cfrac%7Bd%7D%7Bdx%7Dx%5En%3Dnx%5E%7Bn-1%7D%2C%5Cfrac%7Bd%7D%7Bdx%7DC%3D0%5D)
It is given that y=2 and dy/dt=1, substitute these values in the above equation.
Divide both sides by 4x³.
Therefore the value of is .
Answer:
y= 5
Step-by-step explanation:
:)
we know that
Two angles are supplementary if their sum is equal to 
degrees
in this problem we have
so
therefore
<u>the answer is</u>
The two angles are supplementary
circumference of the mirror = 175.84 cm
area of the mirror = 2461.76 cm²
The measure needed to find the amount of wire round the mirror is the circumference.
The measure needed to find the amount of glass needed is the area.
<h3>How to find area and circumference of a circle?</h3>
The circumference and area of a circle can be found as follows:
circumference of the mirror = 2πr
circumference of the mirror = 2 × 3.14 × 28 = 175.84 cm
area of the mirror = πr²
area of the mirror = 3.14 × 28²
area of the mirror = 2461.76 cm²
The measure needed to find the amount of wire round the mirror is the circumference.
The measure needed to find the amount of glass needed is the area.
