Answer:

d y dx=0

Explanation:

From the given

y=sin2x+cos2x

The right side of the equation is

y=1

d y d x=d d x(1)=0

or we can do it this way.

y = sin2x+cos2x

d y d x=2

⋅(sinx)2−1

⋅

d d x(sinx)+2

(cosx)2−1 d d x(cosx)

d y d x=2⋅

sinx⋅cosx+2⋅cosx⋅(−sinx)

dydx=2⋅sinx⋅cosx−2⋅sinx⋅cosx

dydx=0

God bless....I hope the explanation is useful.

Determine the account balance of a simple interest account if the principal is $10,000, the interest rate is 1.5%, and the time

AnnZ [28]

Answer:

Capital: 2 400

Tasa: 5% = 5/100 = 1/20

Tiempo: 4 años

A) Interés = capital*tasa*tiempo

Interés = 2400*(1/20)*4

Interés = 480 soles

B) Interés = Capital*((1 + tasa)^tiempo+1)

Interés = 2400*((1 + 1/20)^4 + 1)

Interés = 2400*((21/20)^4 + 1)

Interés = 2400*(194 481/160 000 + 1)

Interés = 2400*(354 481/160 000)

Interés = 5 317,215Step-by-step explanation:

Kelly has a rock garden with a length of 6 feet. She constructs a scale model of the rock garden using the scale 1 inch:2 feet.

melamori03 [73]

Answer:

Part a) 3 inches

Part b) Yes, her scale model drawing will fit on the piece of paper 8.5 by 7 inches

Step-by-step explanation:

we know that

The scale drawing is

$1\ inch:2\ feet$

That means

1 inch in the model represent 2 feet in the actual

Part a) What is the length of the garden in her model?

we know that

The length of the garden is 6 feet in the actual

Find out the length of the garden in her model, using proportion

$\frac{1}{2}\ \frac{in}{ft}=\frac{x}{6}\ \frac{in}{ft}\\\\x=6/2\\\\x=3\ in$

Part b) If the width is 5 inches for the scale model and the scale is still 1 inch to 2 feet, will her scale model drawing fit on a piece of paper that is 8.5 inches by 7 inches? Why or why not?

we know that

The model width is described as 5 inches. Both the 3-inch length and the 5-inch width are less than the 8.5 inch and 7 inch dimensions of the paper Kelly is using.

therefore

She can easily draw her model on that size paper.
