Answer:

{x\ x e U and x has a negative square root} is an empty set.

Step-by-step explanation:

If x e U, x is a negative real number, and they don't have a square root (they don't have even roots). Their square roots are complex numbers, not real ones.

The set that will give an empty set will be {x|x ∈ U and x has a negative square root}

A set is a collection of numbers or objects. They are not necessarily arranged in pattern.

Given the following sets

r U = {x|x is a negative real number}

We are to determine the set that is empty. This means we need the set of numbers that are not real numbers.

The square root of a negative number will give a complex number. Hence the set that will give an empty set will be {x|x ∈ U and x has a negative square root}

Measures of the given angles:

∠S = 25° and ∠R = 47°

In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle.

There are two main parts related to an angle - the arms and the vertex.

Given,

Measure of angle R is 3 degrees less than twice the measure of angle S

⇒ 2∠S - ∠R = 3°        

⇒ ∠R = 2∠S - 3°         ------(a)

Sum of R and S

⇒ ∠R + ∠S = 72°      

Substituting ∠R in terms of ∠S in above equation from equation (a)

2∠S - 3° + ∠S = 72°

3∠S - 3° = 72°

3∠S = 72° + 3°

3∠S = 75°

∠S = 75°/3

∠S = 25°

Substituting value of ∠S in equation (a)

∠R = 2 × 25° - 3°

∠R = 50° - 3°

∠R = 47°

Hence, ∠S = 25° and ∠R = 47° are the measures of given angles.

Step-by-step explanation:

ratio - 0:7

in percentage=0÷7×100

A linear function in slope intercept form is

y = mx + c

To find the equation, you need m and c. This can be found by substituting the points you have.

For example, 5 = -1(m) + c and -7 = 2(m) + c

From here, do simultaneous equations

c = m + 5

-7 = 2(m) + m + 5

3m = -7 -5

m = -4

c = m + 5

c = 1

Rewrite the equation: (This is your answer)

y = -4x + 1

Answer:

Jamie has a  foot plank that he needs to cut into 1/9 pieces.

15 ÷ 1/9 = 135  

135 x 1/9 = 15

Step-by-step explanation:

Jude divided 15 pizzas bought into 1/9 pieces each. what is the total number of pizzas are we having?

This is a way of representing equations using real-world applications.

Given the expression 15 divided by 1/9, we can create a story to represent the expression. For instance;

Let the number of pizzas we have to be x

x = 15/(1/9)

x = 15 * 9/1

x = 135

Hence there are 135 pieces of pizzas

To solve this question, we must know the the angle sum property of a triangle. Therefore the value of ∠⁡⁣B is 85° when ∠A = 75° and ∠C=20° in △ABC

According to angle sum property of a triangle, the sum of all angles of a triangle is always 180 degree. It can never be more than or less than 180 degree. If two angles of a triangle is given then the third angle can be calculated by subtracting the sum of two angle from 180°

The sum of the three angles in a triangle = 180° , that is

∠ A + ∠ B + ∠ C = 180°

Substituting the given values in the given equation we get

75° + ∠ B + 20° = 180°

∠ B + 95° = 180°

subtracting 95° from both sides we get

∠ B = 85°

Therefore  the value of ∠⁡⁣B is 85° when ∠A = 75° and ∠C=20° in △ABC

Answer: 20°, 50° and 90°

Step-by-step explanation:

From the question, we are informed that the measures of the three angles whose sum is 160 are in the extended ratio ​2:​5:9.

The exact angle measures will then be:

= 2/(2+5+9) × 160°

= 2/16 × 160°

= 20°

= 5/(2+5+9) × 160°

= 5/16 × 160°

= 50°

= 9/(2+5+9) × 160°

= 9/16 × 160°

= 90°

Answer:

7/12

Step-by-step explanation:

the least common denominator is 12

4 goes into 12 three times so you multiply both numbers in 3/4 by three

3/4 = 9/12

6 goes into 12 twice so multiply both the 1 and 6 by two

1/6 = 2/12

so the equation becomes 9/12 - 2/12

subtract the numerators

9-2= 7

7/12 can't be simplified any farther so that's the final answer

Answer:

  a = √(b² +c² -2bc·cos(A))

  a = √(c² -b²)

Step-by-step explanation:

For sides a, b, c, and opposite angles A, B, C, the general form of the law of cosines is ...

  a² = b² + c² -2bc·cos(A)

An expression for 'a' can be written by taking the square root.

  a = √(b² +c² -2bc·cos(A))

__

If you recognize that cos(A) = b/c, then a substitution can be made:

  a = √(b² +c² -2(bc)(b/c)) = √(b² +c² -2b²)

  a = √(c² -b²) . . . . . . . same as the Pythagorean theorem

Step-by-step explanation:

The area of the shape in Step n is (n+1)²-2.

A recurring arrangement of numbers, forms, colours, and other elements constitutes a pattern in mathematics. The Pattern can be connected to any kind of occasion or thing. When a group of numbers are arranged in a particular way, the arrangement is referred to as a pattern. Patterns can also occasionally be referred to as a series.

From the given pattern,

Area of the shape in step 1 is 2 square centimeter

Area of the shape in step 2 is 7 square centimeter

Area of the shape in step 3 is 14 square centimeter

Here, the pattern is 2²-2=2

3²-2=7

4²-2=14

so, the general form is (n+1)²-2

Therefore, the area of the shape in Step n is (n+1)²-2.
