Answer:

C

Step-by-step explanation:

Use the sum of cubes factoring rule

[tex]a^3 + b^3 = (a+b)(a^2 - ab + b^2)[/tex]

to transform the left hand side into the right hand side.

[tex]\frac { \sin^{3} \theta + \cos^{3} \theta } { \sin \theta + \cos \theta } = 1 - \sin \theta \cdot \cos \theta\\\\\frac { (\sin \theta + \cos \theta)(\sin^2 \theta - \sin \theta \cdot \cos\theta + \cos^2 \theta) } { \sin \theta + \cos \theta } = 1 - \sin \theta \cdot \cos \theta\\\\[/tex]

[tex]\sin^2 \theta - \sin \theta \cdot \cos\theta + \cos^2 \theta = 1 - \sin \theta \cdot \cos \theta\\\\(\sin^2 \theta + \cos^2\theta)- \sin \theta \cdot \cos\theta = 1 - \sin \theta \cdot \cos \theta\\\\1- \sin \theta \cdot \cos\theta = 1 - \sin \theta \cdot \cos \theta \ \ \checkmark\\\\[/tex]

Throughout the entire process, the right hand side stayed the same.

On the last step, I used the pythagorean identity.

Answer:

610.5

Step-by-step explanation:

First, we have to organize the data. We know that:

Mary the Manager slept for 999 hours,

Cam the Cashier slept for 333 hours,

Teddy the Truck Driver slept for 777 hours,

Sierra the Security Guard slept for 444 hours.

Next, we have to the the median number of hours of sleep.

To find the median:

First, we have to order the numbers from least to greatest. In this problem that is 333, 444, 777, 999. in an odd amount of numbers, like 5, the middle number is the median. In this case, however, there is not an odd amount of numbers, there are 4 numbers. Which means, we have to do the odd number equation:

We have to add the two middle numbers, which are 444, and 777 together, which results in 1,221. Finally, we must divide the result in half, which gives us out final total of 610.5

Answer:  2 3/10

Step-by-step explanation: I got it correct on k12 .

The value of Z is 2.3 (as a decimal) or 2 3/10 (as a mixed number in simplest form).

The diameter of a circle or sphere is the length of a straight line that passes through the center of a body or figure, notably a circle or sphere.

The diameter of the circle is 11 4/5 ft, which can be written as:

11 4/5 ft = 11 + 4/5 ft = (11 x 5)/5 + 4/5 ft = 55/5 + 4/5 ft = 59/5 ft

The formula to calculate the radius of a circle using the diameter is:

radius = diameter/2

So, the radius of the circle is:

radius = (59/5)/2 = 59/10 ft

Now, we can use the given expression to represent the radius in terms of Z:

radius = Z + 3.6

Substituting the value of the radius, we get:

59/10 = Z + 3.6

Subtracting 3.6 from both sides, we get:

59/10 - 3.6 = Z

Multiplying both sides by 10, we get:

Z = 59/10 - 36/10

Z = 23/10

Therefore, Z = 2 3/10.

Answer:

1. The cylinder has a greater volume of 352 cm to 240 cm for the rectangular prism. Work shown below. Place into your own words.

2. The cylinder has a greater surface area than the rectangular prism at 276 cm instead of 268 cm. Work shown below. Place into your own words.

Step-by-step explanation:

First you have to know the formula for the Volume of the objects

For rectangular prism its: Width x Length x Height

For a cylinder its: Height x pi x Radius^2

With this information you can plug in the information that you already have

For rectangular prism: 10 cm x 8 cm x 3 cm = 240 cm

For the cylinder you have to find radius since its not given to you, while your diameter is, so your radius is diameter/2

For the cylinder: 7 cm x pi (3.14) x 4 cm^2 = 351.858 or 352 cm

1. So therefore, the cylinder has a greater volume because it is greater in centimeters

For the second question, the formula are changed since its now asking for Surface Area

You have to remember that surface area is all the surfaces that are outside the prism, or all the surfaces of the object

Surface Area formula for a rectangular prism is: 2( wl + hl + hw)

Surface Area formula for a cylinder is: 2πrh+2πr^2

All you have to do now is plug in your information

SA for rectangular prism: 2 ((10x8) + (3x8) + (10x3)) = 2 ((80) + (24) + (30)) =

2 (134) = 268 cm

SA for a cylinder: 2 x pi (3.14) x 4 x 7 + 2 x pi (3.14) x 4^2 = 175.929 + 100.531 = 276.460 or just 276 cm

So once again, the cylinder has a greater surface area than the rectangular prism

Answer: D

Step-by-step explanation:

The correct answer is D because absolute value is the distance a number is from 0, which in this case is 16. Absolute value cannot be negative as a distance cannot be negative.

Answer:

D

Step-by-step explanation:

absolute value is how far it is from 0, so any negative number is just the same number but positive. think of it like distance, something can be 10 inches to the right, or to the left. absolute value doesn't care which direction it goes, noon y absolute would call the left -10

Answer:

Question 1

This is a special triangle as the angles are 30-60-90

This means that the sides have a special ratio of
1 : √3 : 2 = short leg : long leg : hypotenuse

So the hypotenuse is twice the length of the short leg,
and the long leg is √3 times the length of the short leg.

Given:

⇒ x = 30 ÷ 2 = 15

⇒ y = 15 × √3 = 15√3

Question 2

The sum of the interior angles of a triangle is 180°.  Therefore the unknown angle of the triangle is 60°.

So again, this is a special 30-60-90 triangle, and we can use the same method as question 1 above.

Given:

⇒ x = 5 × √3 = 5√3

⇒ y = 5 × 2 = 10

Question 3

Pythagoras' Theorem:  a² + b² = c²

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

To find x:

Given:

⇒ 8² + 6² = x²

⇒ x² = 100

⇒ x = √100

⇒ x = 10

To find y:

Given:

⇒ 5² + 10² = y²

⇒ y² = 125

⇒ y = √125

⇒ y = 5√5

Question 4

Pythagoras' Theorem:  a² + b² = c²

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

To find x:

Given:

⇒ 5² + 12² = x²

⇒ x² = 169

⇒ x = √169

⇒ x = 13

To find y:

Given:

⇒ y² + 13² = 14²

⇒ y² + 169 = 196

⇒ y² = 27

⇒ y = √27

⇒ y = 3√3

Answer: the first one, top left corner

Step-by-step explanation:

The last table has a constant slope of -3, hence it represents a linear function.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

To determine that, we must check which of the table has a constant rate of change

Looking at the last table;

Slope = -4-(-2)/2-1

Slope = -4+1/1

Slope = -3

Since the last table has a constant slope of -3, hence it represents a linear function.

Hence, the last table has a constant slope of -3, hence it represents a linear function.
