Cos(x+y)cos(x-y)=cos^2y - sin^2x

Answers

cos(x + y) cos(x - y) = (cos(x) cos(y) - sin(x) sin(y)) (cos(x) cos(y) + sin(x) sin(y))

… = (cos(x) cos(y))² - sin(x) sin(y) cos(x) cos(y) + sin(x) sin(y) cos(x) cos(y) - (sin(x) sin(y))²

… = (cos(x) cos(y)) - (sin(x) sin(y))²

… = cos²(x) cos²(y) - sin²(x) sin²(y)

… = (1 - sin²(x)) cos²(y) - sin²(x) sin²(y)

… = cos²(y) - sin²(x) cos²(y) - sin²(x) sin²(y)

… = cos²(y) - sin²(x) (cos²(y) + sin²(y))

… = cos²(y) - sin²(x)

4.A peach weighs 55 grams. If you buy 6 peaches and they sell for $5.50 per kilogram, how
much will they cost?

Answers

Answer:

1.815

Step-by-step explanation:

1peach=55grams

6peaches=?

55*6=330grams

1kg=1000grammes

    =330grams

330 divide 1000=0.33

                    1kg=5.50

              0.33kg=                                Hence,0.33*5.50=1.815

The area of a triangle is 36 square inches. What is the height of the triangle if the base length is 8 inches? (3 points) a 8 inches b 9 inches c 12 inches d 6 inches

Answers

9514 1404 393

Answer:

  b.  9 inches

Step-by-step explanation:

The area of a triangle is given by ...

  A = 1/2bh

Solving for h, we get ...

  h = 2A/b

  h = 2(36 in²)/(8 in) = 72/8 in

  h = 9 in

The height of the triangle is 9 inches.

Select the function that is nonlinear.

b
y = 2x3 - 10

y = 4x -12

d

Answers

B
Because all of the other equations are in the linear format of y=mx+b while B has the extra 3 added on to it.
Hope this helps!!

Answer:

B

Step-by-step explanation:

A C and D are all linear. The powers on x in all three questions is 1. For example the first answer could be written as y = 3x^1 - 4. C and D are much the same.

So if you are thinking that B must be the answer, you would be right. x is raised to the third power --  or I think that is what is intended. y = x^3 - 10

A conglomerate of Christmas tree growers in Oregon wants to know if there is a difference in preference for live Christmas trees between urban and rural regions of the state. They randomly surveyed 160 rural households that put up a Christmas tree the previous season and found that 64 had used a live tree. In a separate random survey, 89 of 261 urban household had put up a live tree the previous season. The 95% confidence interval for the difference of the true proportion of all households (rural - urban) in Oregon that preferred a live tree is between -0.036 and 0.154. Based on the confidence interval, is there convincing evidence that the two population proportions are different

Answers

Answer:

0 is part of the confidence interval, which means that there is not convincing evidence that the two population proportions are different.

Step-by-step explanation:

Based on a confidence interval for the difference of proportions, there will be significant evidence that the proportions are different if 0 is not part of the confidence interval for the difference of proportions.

In this question:

Confidence interval between -0.036 and 0.154

0 is part of the confidence interval, which means that there is not convincing evidence that the two population proportions are different.

Answer:

Answers

Answer:

16x² + 64x + 64

Step-by-step explanation:

Given

A = 16x²

Increasing the sides by 2, substitute x = x + 2 into A

A = 16(x + 2)² ← expand factor using FOIL

   = 16(x² + 4x + 4 ) ← distribute

In the coordinate plane, line p has slope 8 and y-intercept (0, 5). Line r is the result of dilating line p by a factor of 3 with center (0, 3). What are the slope and y-intercept of line r?

A.
Line r has slope 8 and y-intercept (0, 9).

B.
Line r has slope 8 and y-intercept (0, 5).

C.
Line r has slope 5 and y-intercept (0, 2).

D.
Line r has slope 11 and y-intercept (0, 8).

Answers

Answer:

im not that smart but

Step-by-step explanation:

Given that In the coordinate plane line p had slope 8 and y intercept (0,5).

Hence equation of line p is

y = 8x+5 (slope intercept form)

When we dilate p by a factor of 3, we have

we find that slope would remain the same but the y intercept would become 3 times.

Hence new line would be

y = 8x+15

Slope = 8 and y intercept = 15

This line will be parallel to original line.

The line r has slope 8 and y-intercept (0, 9) and the equation of the line is y = 8x + 9 if the line p has slope 8 and y-intercept (0, 5). Line r is the result of dilating line p by a factor of 3 with center (0, 3) option (A) is correct.

What is a linear equation?

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

We have:

p has a slope of 8 and y-intercept (0, 5)

Line r is the result of dilating line p by a factor of 3 with center (0, 3).

Line p is:

y = 8x + 5

The center is not on the line because it does not satisfy the line.

Now dilated line r will have the same slope.

And inetercept = 3+3(5-3)

= 9

Thus, the line r has slope 8 and y-intercept (0, 9) and the equation of the line is y = 8x + 9 if the line p has slope 8 and y-intercept (0, 5). Line r is the result of dilating line p by a factor of 3 with center (0, 3) option (A) is correct.
