It appears that the derivatives of sine and cosine are related. What about the second derivatives?.
Andru [333]

Answer:

Step-by-step explanation:

\frac{d}{dx} (sin~x)=cos~x\\\frac{d}{dx}(cos~x) =-sin~x\\\frac{d^2}{dx^2} (sin~x)=\frac{d}{dx} (cos~x)=- sin~x\\\frac{d^2}{dx^2} (cos~x)=\frac{d}{dx} (-sin~x)=-cos~x

Bess [88]

Answer:

12566.4 mm²

Step-by-step explanation:

The Petri dish shown has no lid. What is the surface area of the outside of the Petri dish? Round to the nearest tenth. A cylindrical-shaped Petri dish with a radius of 50 millimeters and a height of 15 millimeters.

TSA = Total Surface Area

CSA = Curved Surface Area

TSA of open cylinder = CSA of cylinder + area of base or top

= 2πrh + πr²

= πr(2h + r)

From the above question:

r = 50mm

h = 15mm

Hence,

= π × 50 (2 × 15 + 50)

= π × 50 (30 + 50)

= π × 50(80)

= π × 4000

= 12566.370614mm²

Approximately = 12566.4 mm²

The Surface Area of the petri dish with no lid = 12566.4 mm²

Write 18 out of 100 as a fraction, as a percent, and as a decimal
raketka [301]

Answer:

Step-by-step explanation:

18/100

0.18

18%

Solve the following problem. Write 18% as a fraction in simplest form.

First, write the percent as a fraction out of 100.

18/100

Next, you simplify this fraction. The greatest common factor of 18 and 100 is 2, so you divide both the numerator and the denominator by 2.

18÷2/100÷2=950

Then, check to ensure that the fraction cannot not be reduced further. In this instance it cannot.

The answer is 18% can be written as the fraction 9/50 in simplest form.
