Answer:

D $175

Step-by-step explanation:

If function f(x)= x² then g(x) is  -x² - 3 , option A is correct.

A relation is a function if it has only One y-value for each x-value.

The reflection in the x-axis changes the sign of the y-coordinate. So, the reflection of f(x) = x² in the x-axis is g(x) = -x².

Secondly, the downward shift of 3 units means subtracting 3 from the y-coordinate.

So, the transformation applied to f(x) to get g(x) is reflection in the x-axis followed by a downward shift of 3 units.

g(x) = -x² - 3 is the result of applying a reflection in the x-axis followed by a downward shift of 3 units to the function f(x) = x².

Hence, if function f(x)= x² then g(x) is  -x² - 3 , option A is correct.

Answer:

B. (5/6)^2

Step-by-step explanation:

A. 2^3

= 2 × 2 × 2

= 8

The base is 2

Therefore, the expression is greater than the base

B. (5/6)^2

= 5/6 × 5/6

= 5*5 / 6*6

= 25/36

Base = 5/6 = 0.833

Expression =25/36 = 0.694

Therefore, the expression is less than the base

C. 3^1

= 3

The base is 3

Therefore, the expression is equal to the base

D. 4^4

= 4 * 4 * 4 * 4

= 256

The base is 4

Therefore, the expression is greater than the base

The correct answer is B. (5/6)^2

Given:

Total number of students = 27

Students who play basketball = 7

Student who play baseball = 18

Students who play neither sports = 7

To find:

The probability the student chosen at randomly from the class plays both basketball and base ball.

Solution:

Let the following events,

A : Student plays basketball

B : Student plays baseball

U : Union set or all students.

Then according to given information,

[tex]n(U)=27[/tex]

[tex]n(A)=7[/tex]

[tex]n(B)=18[/tex]

[tex]n(A'\cap B')=7[/tex]

We know that,

[tex]n(A\cup B)=n(U)-n(A'\cap B')[/tex]

[tex]n(A\cup B)=27-7[/tex]

[tex]n(A\cup B)=20[/tex]

Now,

[tex]n(A\cup B)=n(A)+n(B)-n(A\cap B)[/tex]

[tex]20=7+18-n(A\cap B)[/tex]

[tex]n(A\cap B)=7+18-20[/tex]

[tex]n(A\cap B)=25-20[/tex]

[tex]n(A\cap B)=5[/tex]

It means, the number of students who play both sports is 5.

The probability the student chosen at randomly from the class plays both basketball and base ball is

[tex]\text{Probability}=\dfrac{\text{Number of students who play both sports}}{\text{Total number of students}}[/tex]

[tex]\text{Probability}=\dfrac{5}{27}[/tex]

Therefore, the required probability is [tex]\dfrac{5}{27}[/tex].

Answer:

55 cm²

Step-by-step explanation:

In a parallelogram, the top base is equal to the bottom base (and the sides are equal to each other too!)

So the top and bottom base are both 9, and the left and right sides are both 5.

So, to solve, we need to use the equation:

(4 + 1) * (9 + 2) = 5 * 11 = 55 cm²

[tex]Q_n=(2000)-(20)P_n[/tex]

Step-by-step explanation:

From the question we are told that:

Initial Quantity demanded Q_1= 200 units

Initial demand price [tex]P_1=\$90[/tex]

Final Quantity demanded [tex]Q_2= 1200 units[/tex]

Final demand price [tex]P_2=\$40[/tex]

Generally the  Demand Equation is mathematically given by

 [tex]Q_n=a-bP_n[/tex]

Where

a=Other factors affecting price

b=Slope of the demand curve

Therefore

 [tex]Q_1=a-bP_1[/tex]

 [tex]200=a-b(90)[/tex]

 [tex]Q_2=a-bP_2[/tex]

 [tex]1200=a-b(40)[/tex]

Comparing both above equations

  [tex]a=2000[/tex]

  [tex]b=20[/tex]

Therefore the  Demand Equation is mathematically given by

  [tex]Q_n=(2000)-(20)P_n[/tex]

Explanation:

In your studies so far, every number you encounter is a real number. This changes when your teacher will introduce complex and imaginary numbers later on down the road. So 3.5 is a real number. A real number is essentially any number we can express as a decimal value (whether the decimal terminates, or goes on forever).

The number 3.5 is also rational because we can express it as a ratio of two integers, aka a fraction of two integers. Specifically, we can say 3.5 = 35/10 = 7/2.

The number 3.5 being rational would automatically rule out "irrational", since "irrational" means "not rational". The number 3.5 isn't an integer either. It would need to be either a positive whole number, negative whole number, or zero for it to be an integer. We rule out "natural number" for similar reasoning that we ruled out "integer".

Answer:

C = 65.94 ft and A = 346.185 ft^2

Step-by-step explanation:

r = d/2 = 21/2 = 10.5

let [tex]\pi[/tex] = 3.14

C = 2[tex]\pi[/tex]r

C = 2(3.14)(10.5) = 65.94 ft

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

A = (3.14)(10.5)^2 = 346.185 ft^2

The solution is: the circumference of the circle is C = 65.94 ft and, the area of the circle A = 346.185 ft^2.

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.

here, we have,

given that,

diameter of the circle = 21

so, we have,

r = d/2

 = 21/2

 = 10.5

let  

π= 3.14

we know that,

the circumference of the circle is:

C = 2rπ

C = 2(3.14)(10.5)

   = 65.94 ft

the area of the circle is:

A =π r^2

A = (3.14)(10.5)^2

  = 346.185 ft^2

Hence, The solution is: the circumference of the circle is C = 65.94 ft and, the area of the circle A = 346.185 ft^2.

Answer:

The answer is below

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, scalene, equilateral, obtuse, acute and right angled triangles.

Two triangles are said to be congruent if all the corresponding sides and angles of both triangles are equal. Congruent triangles have the same size and shape.

Given that AB || DC and AD || BC, therefore:

∠DCA = ∠BAC (alternate angles are equal)

∠DAC = ∠BCA (alternate angles are equal)

AC ≈ AC

Therefore from triangle ABC and triangle CDA, since ∠DCA = ∠BAC, ∠DAC = ∠BCA and AC ≈ AC, hence both triangles are congruent by Ange-side-angle congruence theorem.

Therefore AB = CD

Answer:

Answer: [tex]84\ mm^2[/tex]

Step-by-step explanation:

Given

The long side of a triangle is 27 mm

The length of the base is 14 mm

height of the triangle is 12 mm

The area of a triangle is given by

[tex]\Rightarrow \dfrac{1}{2}\times \text{base}\times \text{height}[/tex]

Insert the values

[tex]\Rightarrow \dfrac{1}{2}\times 14\times 12\\\\\Rightarrow 84\ mm^2[/tex]

Thus, the area of the triangle is [tex]84\ mm^2[/tex]

Answer:

The base of the triangle has a length of 26 meters, and the height of the triangle has a length of 13 meters.

Step-by-step explanation:

Equation to find the height: [tex]\frac{2x*x}{2} = 169[/tex] ⇒ [tex]x^2=169[/tex] ⇒ [tex]x=13[/tex] meters.
