Answer:

[tex]cos^{4}[/tex] x

Step-by-step explanation:

Using the trigonometric identities

1 + tan²x = sec²x and 1 - sin²x = cos²x

secx = [tex]\frac{1}{cosx}[/tex]

Given

[tex]\frac{1-sin^2x}{1+tan^2x}[/tex]

= [tex]\frac{cos^2x}{sec^2x}[/tex]

= [tex]\frac{cos^2x}{\frac{1}{cos^2x} }[/tex]

= cos²x × cos²x

= [tex]cos^{4}[/tex] x

Final answer:

The integer representing the temperature drop of 28°, leaving the thermometer at 48°, is -28. The original temperature before the drop was 76°.

Explanation:

The integer that represents the number of degrees the temperature drops when the temperature drops 28° and the thermometer reads 48° afterwards is -28. To find this, we use the final temperature (48°) and add the temperature drop (28°) to determine the original temperature. However, since it is a temperature drop, we have to add a negative sign to the drop, making it -28°. Therefore, the original temperature was 48° + 28° = 76°. The decrease in temperature is represented by the negative integer -28°.

Hello!

3,486 / 2 = n

n = 1743

work:

you simply divide 3,486 by 2

if you divide each number by two (right to left)

6 / 2 = 3

8 / 2 = 4

4 / 2 = 2

3 / 2 = 1.5

since there is a decimal in this, multiply it by 10 and add it to the number before. this number will go on the right side of the total

1.5 * 10 =15

15 + 2 = 17

17 4 3 are the final numbers in order. put them together and you have 1743

(this is my personal way of doing it, but there are plenty more ways to do it)

I hope this helps, and have a nice day!

Answer:

0.75x + 0.8(x + 10) = 101

Step-by-step explanation:

Write an expression to represent the number of shots each one made.

Jared attempted x shots and made 75% of them, or 0.75x.

Zach attempted 10 more shots than Jared did, which is represented as x + 10. He made 80% of them, or 0.8(x + 10).

Together, they made 101 shots. So, add the two expressions and set the sum equal to 101:

0.75x + 0.8(x + 10) = 101.

Answer:

For the length of time less than 6 hours cost less to hire Hanks movers

Step-by-step explanation:

Let

x -----> the time in hours

y ----> the total cost in dollars

we know that

Acme movers

[tex]y=30x+150[/tex] ----> equation A

Hanks movers

[tex]y=55x[/tex] ----> equation B

Equate equation A and equation B and solve for x

[tex]55x=30x+150[/tex]

[tex]55x-30x=150[/tex]

[tex]25x=150[/tex]

[tex]x=6\ hours[/tex]

That means-----> For x= 6 hours The cost in both companies is the same

Verify

For x=6 hours

Acme movers

[tex]y=30(6)+150=\$330[/tex]

Hanks movers

[tex]y=55(6)=\$330[/tex]

If x < 6 hours ----> It cost less to hire Hanks movers

If x > 6 hours ----> It cost less to hire Acme movers

therefore

For the length of time less than 6 hours cost less to hire Hanks movers

Answer: One 8-cm pipe (Its is greater than the total area of of two 4-cm pipes)

Step-by-step explanation:

The area of a circle can be calculate with this formula:

[tex]A=\pi r^2[/tex]

Where "r" is the radius of the circle.

We need to calculate the area of 8-cm pipe. In this case:

[tex]r=8cm[/tex]

Then, substituting the radius into the formula, we get:

[tex]A=\pi (8cm)^2\\\\A=201.06cm^2[/tex]

Now we must calculate the area of the two 4-cm pipes.

Since they are two pipes, the formula is:

[tex]A=2\pi r^2[/tex]

In this case:

[tex]r=4cm[/tex]

Then, substituting into the formula, we get:

[tex]A=2\pi (4cm)^2\\\\A=100.53cm^2[/tex]

Therefore, since the area of one 8-cm pipe is greater than the total area of of two 4-cm pipes, we conclude that the pipe configuration that can deliver more water to residents is:

One 8-cm pipe

Answer:

It will cost 4 cents to print a page using the MOST EXPENSIVE cartridge than using the LEAST EXPENSIVE cartridge .

Step-by-step explanation:

Cartridge           Price            Printed Pages

Cartridge A        $36.00              300

Cartridge B        $67.50               450

Cartridge C        $70.00              500

Cartridge D        $66.00              600

Cartridge E        $84.50              650

Cost of printing 300 pages with Cartridge A = $36

Cost of printing 1 page with Cartridge A = [tex]\frac{36}{300}=0.12[/tex]

Cost of printing 450 pages with Cartridge B = $67.50

Cost of printing 1 page with Cartridge B=  [tex]\frac{67.50}{450}=0.15[/tex]

Cost of printing 500 pages with Cartridge C = $70

Cost of printing 1 page with Cartridge C =  [tex]\frac{70}{500}=0.14[/tex]

Cost of printing 600 pages with Cartridge D = $66

Cost of printing 1 page with Cartridge D =  [tex]\frac{66}{600}=0.11[/tex]

Cost of printing 650 pages with Cartridge D = $84.50

Cost of printing 1 page with Cartridge D =  [tex]\frac{84.50}{650}=0.13[/tex]

Based on the unit price per page most expensive cartridge B and least expensive cartridge is Cartridge D.

So, Difference between the unit price of most expensive cartridge B and least expensive cartridge is Cartridge D = $0.15-$0.11 = $0.04

$1 = 100 cents

$0.04 = 4 cents

Hence it will cost 4 cents to print a page using the MOST EXPENSIVE cartridge than using the LEAST EXPENSIVE cartridge .

Answer:

Prime.

Step-by-step explanation:

A^2+4a+12

Not factorable.

More gallons of water in the tank have 2/5 water in it

Solve for a:

3a +11 > 5

Subtract 11 from both sides:

3a >-6

Divide both sides by 3:

a > -6/3

a > -2

The Correct graph is the second one, because it has the dot on the -2 and the arrow points to the right

The 2 number line shows the solutions to the inequality 3a + 11 > 5 and the correct option is B.

The image shows two number lines, and asks which one shows the solutions to the inequality 3a + 11 > 5.

To solve this inequality, we can subtract 11 from both sides, and then divide both sides by 3. This gives us a simpler inequality: a > -2.

This means that all values of a that are greater than -2 are solutions to the inequality. On a number line, this can be represented by an open circle at -2, and an arrow pointing to the right.

The number line on the left of the image shows exactly this. Therefore, the number line on the left shows the solutions to the inequality 3a + 11 > 5.

The number line on the right of the image does not show the solutions to the inequality correctly. The open circle at -2 is missing, and the arrow points to the left, which is incorrect, since the solutions to the inequality are all values of a that are greater than -2, not less than -2.

Here is a more detailed explanation of the steps involved in solving the inequality:

1. Subtract 11 from both sides:

3a + 11 > 5

-11 - 11

3a > -6

2. Divide both sides by 3:

3a > -6

3 / 3

a > -6 / 3

3. Simplify:

a > -2

Therefore, the solution to the inequality is a > -2. On a number line, this can be represented by an open circle at -2, and an arrow pointing to the right.

The number line on the left of the image shows exactly this. Therefore, the 2 number line on the left shows the solutions to the inequality 3a + 11 > 5 and the correct option is B.

The factors of [tex]x^{2} + 9 x + 8[/tex] is (x + 8)(x +1)  

Solution:

From question, given that [tex]x^{2} + 9x + 8[/tex]

To factorise the given equation, follow the below steps:

9x can be rewritten as 8x + 1x. Hence the above given equation becomes,

[tex]x^{2} + 9x + 8 = x^{2} + 8x + 1x + 8[/tex]

Rearranging the terms, we get

[tex]= x^{2} + 1x + 8x + 8[/tex]

Taking x as common from first two terms and 8 as common from last two terms, the above equation becomes,

= x(x+1)+8(x+1)

Since (x +1) is common in both the terms, we get

= (x +1)(x+8)

Hence the factors of [tex]x^{2} + 9x + 8[/tex] is (x + 8)(x +1)

To use the distributive property and mental math to find 5 times 8.9, break down 8.9 into 8 and 0.9, multiply each by 5, and sum the products to get 44.5.

The solution obtained is,

To find the product of 5 and 8.9 using the distributive property and mental math, we can break down 8.9 into 8 and 0.9 for easier multiplication. Thus, 5(8 + 0.9) = (5 × 8) + (5 ×0.9). Calculating each part separately, we get 40 and 4.5. Finally, by adding these two products together, we find that 5(8.9) equals 40 + 4.5, which is 44.5.

Answer:

each book costs $13

Step-by-step explanation:

Let the cost of each book be $x

cost of buying 8 books = $8x

It is given that with an original amount of $116, after buying 8 books, he had $12 left over. Hence,

$8x + $12 = $116   (dropping the $ signs)

8x + 12 = 116

8x = 116 - 12

8x = 104

x = 13  (each book costs $13)

Answer:

he possibly spent $13 on order to end up with $12 left.

Step-by-step explanation:

1) look. at the number 116 you can use a calculator.

Answer:

(- 1, 9 )

Step-by-step explanation:

A translation of 3 units left, subtract 3 from the original x- coordinate

A translation of 1 unit up, add 1 to the original y- coordinate.

The rule is (x, y ) → (x - 3, y + 1 ), thus

(2, 8 ) → (2 - 3, 8 + 1 ) → (- 1, 9 )

The image point of (2,8) is (-1,9).

The term P', which is pronounced "P prime," is used to refer to the reflection of point P across the line, which is considered to be the "image" of point P.

Given point is (2,8).

And the translation is left 3 unit and up 1units of the point (2,8)

By increasing or decreasing the output or the input, you may change the direction of the function's graph to the right, left, up, or down. A function's output can be increased to shift the graph up. The graph is shifted downward when a function's output is subtracted from.

That means -3 and +1 respectively.

Now the image point of (2,8)

= (2-3, 8+1)

= (-1, 9)

Therefore, the image point is (-1,9).
