Answer is D) [tex]g(x)=(x+1)^2+3[/tex]

Step-by-step explanation:

[tex]f(x)=(x-h)^2+k[/tex]

h = shift left or right

k = shift up or down.

Given:

h = -1 , k = 3

Put that into the equation f(x)

[tex]f(x)=(x-(-1))^2+(3)\\f(x)=(x+1)^2+3[/tex]

The end behavior of the function f(x) describes the behavior of the function as x approaches the +∞  f(x) approaches to 1/2 and the x approaches the -∞  f(x) approaches to 1/2.

It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

[tex]\rm f(x) = \dfrac{4x-7}{8x+8}[/tex]

For the end behavior:

As x → ∞  f(x) → 1/2

And x → -∞ f(x) → 1/2

Thus, the end behavior of the function f(x) describes the behavior of the function as x approaches the +∞  f(x) approaches to 1/2 and the x approaches the -∞  f(x) approaches to 1/2.

The amount of money she spends per year on utility bills for the air conditioner is; D: $176.40

We are told that;

Cost of running the air conditioner = 7 hours per day

Cost of running the air conditioner = 21 cents per hour = $0.21 per hr.

She runs it for four months at 7 hours per day. Thus;

Total number of hours for the 4 months = 7 × 30 × 4 = 840 hours

Total cost for the 4 months = $0.21 per hr. × 840 hours = $176.4

The different parts of a circle are radius, diameter, chord, tangent, arc, centre, secant, sector. Write down the circle formulas. If “r” is the radius of the circle, then the formula for the area and the circumference of a circle are:

An equation is formed of two equal expressions. The value of x that can satisfy this equation is 1.875.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

The model represents the equation as given below,

[tex](6 \times -x)+(6 \times 1) = (2 \times x) + (9 \times -1)\\\\-6x+6=2x-9\\[/tex]

The value of x that can satisfy this equation can be written as,

[tex]-6x+6=2x-9\\\\-6x-2x=-9-6\\\\-8x = -15\\\\8x=15\\\\x = \dfrac{15}{8} = 1.875[/tex]

Hence, the value of x that can satisfy this equation is 1.875.

Answer:

Step-by-step explanation:

There is no pair of real numbers that have a total of -4 and a product of 5. The complex numbers (-2+i) and (-2-i) will meet your requirements.

__

If the numbers of interest are 'a' and 'b', they will be zeros of the quadratic whose factored form is ...

  (x -a)(x -b) = 0

Expanding that, we find an opportunity to use the given sum and product numbers:

  x² -(a+b)x +ab = 0

  x² -(-4)x +5 = 0

Rewriting this in vertex form gives ...

  (x² +4x +4) +1 = 0

  (x +2)² +1 = 0

We can find the values of x by subtracting 1 and taking the square root.

  (x +2)² = -1

  x +2 = ±√(-1) = ±i

  x = -2±i

The two numbers of interest are -2+i and -2-i.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Formula : ( surface area of a cone )_________________________

The total surface area = The curved surface area + area of the base

____________________________________________________

→The curved surface area = π × r × g = π × r × (√(h2 + r2))

 where g is the slant height of the cone and r is the radius of the base

 and h is the height of the cone

 and g = √(h2 + r2)

→Area of the base = π × r²

We get :

The curved surface area = π × r × (√(h2 + r2))

                                         = π × 5.1 × √(14^2+(5.1)^2)

                                         = 238.729625746288                                        

Area of the base = π × r²

                            = π × (5.1)^2

                            = 81.712824919871

Conclusion:

The total surface area = The curved surface area + area of the base

                                     = 238.729625746288 + 81.712824919871

                                     = 320.442450666159

If the first cube lands on a 4, then the second cube must land on 4 5 or 6.

It cannot land on 5 because that would make it the sum odd. (4 + 5 = 9)

So that leaves 4 and 6. You cannot use 2 because 4 + 2 = 6. The sum must be greater than 6.

So we are left with 2 results. The second cube should be 4 or 6

The results are 4 and 4

The value that can take the place of "?" is -6a. The length of line AB is 6a units.

The distance or length of any line on the graph,

[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where,

d = distance/length of the line between point 1 and 2,

(x₁ , y₁) = coordinate of point 1,

(x₂ , y₂) = coordinate of point 2,

The length of a line with two points known is written as,

[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Given the coordinate of points A and B are (-3a,b) and (-3a,b), respectively. Therefore, the length of the line AB can be written as,

[tex]AB = \sqrt{(-3a-3a)^2+(b-b)^2}\\\\AB = \sqrt{(-6a)^2+(0)^2}\\\\AB = 6a[/tex]

Hence, the length of line AB is 6a units.

Step-by-step explanation:

First off, great job on answering the rest! Kevin worked the fastest because he has the lowest time spent per flyer. This means that for every flyer he spent time working on, he would complete it faster than Bill or Dante. This can also be estimated from the table given because although kevin only made 6, he spent only 24 minutes while Bill spent 56 minutes and only made 8. The smaller minutes spent in comparison to the amount of flyers made shows that Kevin is the fastest.

Answer:

21

Step-by-step explanation:

The pattern goes +5 , -2

From 7 you add 5, and than from 12 you minus 2. If you keep this up you get the following numbers.

7,12,10,15,13,18,16,21,19,24,22,27,25,30...ect

21 is the 8th term in the patterns so thats your answer.

The eighth term in the given number pattern is 21. This is obtained by the logic, of adding 5 and subtracting 2.

These keep a relationship between a series of numbers. That relationship is given by logic.

Some of the examples are like Even number pattern, Odd number pattern, Fibonacci series, etc.

Given that the number pattern is 7,12,10,15,13....

In this pattern 7 is the first term

So, the logic is adding 5 and subtracting 2

7+5=12 (2nd term)

12-2=10 (third term)

10+5=15 (fourth term)

15-2=13 (fifth term)

13+5=18 (sixth term)

18-2=16 (seventh term)

16+5=21 (eighth term)

Therefore, the eighth term is 21.
