Prove that sin^4x + cos^4x= sinxcosx

Answers

Answer:

(the relation you wrote is not correct, there may be something missing, so I will simplify the initial expression)

Here we have the equation:

[tex]sin^4(x) + cos^4(x)[/tex]

We can rewrite this as:

[tex](sin^2(x))^2 + (cos^2(x))^2[/tex]

Now we can add and subtract cos^2(x)*sin^2(x) to get:

[tex](sin^2(x))^2 + (cos^2(x))^2 + 2*cos^2(x)*sin^2(x) - 2*cos^2(x)*sin^2(x)[/tex]

We can complete squares to get:

[tex](cos^2(x) + sin^2(x))^2 - 2*cos(x)^2*sin(x)^2[/tex]

and we know that:

cos^2(x) + sin^2(x) = 1

then:

[tex]1 - 2*sin(x)^2*cos(x)^2[/tex]

This is the closest expression to what you wrote.

We also know that:

sin(x)*cos(x) = (1/2)*sin(2*x)

If we replace that, we get:

[tex]1 - \frac{sin^2(2*x)}{2}[/tex]

Then the simplification is:

[tex]cos^4(x) + sin^4(x) = 1 - \frac{sin^2(2*x)}{2}[/tex]

A tablet sales associate makes $84 each day that she works and makes approximately $33 in commission for each tablet that she sells. If she wants to make at least $348 in one day, at least how many tablets does she need to sell?

Answers

Answer:

8 tablets

Step-by-step explanation:

t = # tablets she must sell

348 = 33t + 84

264 = 33t

t = 8

The sales associate needs to sell at least 8 tablets in order to make at least $348 in one day.

To determine the minimum number of tablets the sales associate needs to sell in order to make at least $348 in one day, we can set up an inequality based on the given information.

Let's denote the number of tablets sold as "x."

Given:

Earnings per day (base pay) = $84

Commission per tablet sold = $33

Desired earnings for the day = $348

The total earnings for the day can be calculated as follows:

Total earnings = Base pay + (Commission per tablet * Number of tablets sold)

Total earnings ≥ Desired earnings

Setting up the inequality:

$84 + ($33 * x) ≥ $348

Simplifying the inequality:

$84 + $33x ≥ $348

Now, let's solve for x:

$33x ≥ $348 - $84

$33x ≥ $264

Dividing both sides of the inequality by $33 (the coefficient of x):

x ≥ $264 / $33

x ≥ 8

Therefore, the sales associate needs to sell at least 8 tablets in order to make at least $348 in one day.

Find the perimeter of this semi-circle with diameter, d = 52cm.

Answers

Perimeter = 133.681 cm

or 52.63 inches.

Step-by-step explanation:

"So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius."

let's use,  πr + 2r

Diameter: 52

Radius: 26 (RAdius is half of the diameter)

πr + 2r (plug in)

pi x 26 + 2(26)

pi x 26 + 52

HELP 25 POINTS +BRAINIEST The weight of a substance measures 3 × 10^-3. grams. Express this weight in standard notation.

Scientific notation is a way of writing very large and very small numbers.

A number in scientific notation has the form  

N

×

10

a

, where  

N

is a number between 1 and 10, and  

a

is a positive or negative integer.

To convert to scientific notation, you move the decimal point until the new form is a number between 1 and 10 (

N

) and then record the exponent (

a

) as the number of places the decimal point was moved.

If you move the decimal to the right, the exponent is negative.

A special CPI is constructed to measure the variation of these products, so that coffee and bread have a weight of 0.35 of the total and egg, ham and cheese 0.1 of the total. variation of the CPI?

Answers

9514 1404 393

Answer:

  The CPI increased 3.42% in Month 2.

Step-by-step explanation:

In a spreadsheet, the weighted sum is easily computed using the SUMPRODUCT( ) function. It multiplies the corresponding values of two arrays, then returns the sum of those products. If one of the values is a weight, then the result is a weighted sum.

Your CPI is computed as the weighted sum of the prices of the individual products. The percentage change is computed in the usual way:

  pct change = ((new value)/(old value) -1) × 100%

Of course, the spreadsheet can format a fraction as a percentage, so the computation of the change can stop after 1 is subtracted from the ratio.

Answers

Answer:

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula. This is X when Z has a p-value of 1-0.01 = 0.99. So it is X when Z = 2.325.

The level is L = 134.6
