The circle below is centered at (4,-1) and has a radius of 3. What is it’s equation?

The values of x are 1/ 5 and 11 respectively.

Algebraic expressions are expressions that are comprised of terms, constants, coefficients, variables and factors.

They are also made up of arithmetic operations made up of subtraction, addition, multiplication, division.

To determine the expressions, we have;

1. Let the number be x

We have the expression as;

6x - 8 = x - 7

collect like terms

6x - x = - 7 + 8

5x = 1

Make 'x' the subject

x = 1/ 5

2. Let the number be x

2x = x + 11

collect like terms

2x - x = 11

x = 11

Thus, the values of x are 1/ 5 and 11 respectively.

The sequence of rigid transformations that will map the preimage ΔABC onto image ΔA'B'C' is Option(a) a reflection across the x-axis, a translation 8 units right, and then a reflection across the x-axis.

Co-ordinates of the points of ΔABC are,

A = (-4, 2)

B = (-6, 2)

C = (-2, 6)

point (x,-y) is the reflection of the point (x,y) across the x-axis.

So, new co-ordinates are,

A = (-4, -2)

B = (-6, -2)

C = (-2, -6)

point (x+8,y) is the translation of the point (x,y) by 8 units right.

So, new co-ordinates are,

A = (4, -2)

B = (2, -2)

C = (6, -6)

Then, the reflection of the point (x,y) across the x-axis is the point (x,-y).

So, new co-ordinates are,

A' = (4, 2)

B' = (2, 2)

C' = (6, 6)

These are the coordinates of ΔA'B'C' so the correct answer is Option(a).

The values of the expression at the domain {-2, 3} are {-8, 4}

The expression is given as

2x^2 + 3x - 10

The domain of the function is given as

{-2, 3}

Rewrite the domain as

x = {-2, 3}

Next, we substitute these values of x in the expression 2x^2 + 3x - 10

So, we have

x = -2:⇒ 2(-2)^2 + 3(-2) - 10 = -8

x = 2:⇒ 2(2)^2 + 3(2) - 10 = 4

The solutions to the equation in the interval are x = π/3, x = 5π/3 and x = π.

A formula for a mathematical equation is one that connects two expressions and expresses their equality using the equals sign (=). In English, an equation is defined as a properly written formula that consists of two expressions connected by an equals sign, however cognates of the word in other languages may have slightly different meanings. For instance, an equation is defined as having one or more variables in French. Finding the variables' values that cause the equality to be true is the first step in solving an equation with variables.

Let's assign a variable to the cosine function, cos(x), and say y = cos (x). Our phrase changes to

4y2 + 2y - 2 = 0

2(2y2 + y - 1) = 0

2y2 + y - 1

= 2y(y+1) - (y + 1)

= (2y - 1)(y + 1)

2(2y-1)(y+1) = 0

y + 1 = 0 = y = -1

The answers cos(x) = 1/2 and cos(x) = -1 result from replacing y with cos(x). Our solutions are x = /3, x = 5/3, and x = on the interval [0, 2], where cos(x) = 1/2 for x = /3 and x = 5/3 and cos(x) = -1.

The function f(x), representing the number of blocks Eva is away from her house after x minutes is

[tex]f(x) = \begin{cases} & 0\text{ if } x= 0\\ & x\text{ if } 0 < x\leq 3 \\ & 3\text{ if } 3 < x\leq 6\\ & x/2\text{ if } 6 < x\leq 12\\ & 6\text{ if } 12 < x\leq 18\\ & 24-x\text{ if } 18 < x\leq 24 \\ & 0\text{ if } x > 24 \end{cases}[/tex]

The graph for the same is attached.

In the question, we are asked to form a graph showing the number of blocks, that Eva is away from her home at x minutes, after she leaves her home.

To form the graph, we first try to make a function for x minutes, f(x), showing the number of blocks Eva is away from her home after x minutes.

Since x represents time, it cannot be negative.

At x = 0, f(x) = 0, as she is at her home at 0 minutes.

Then, Eva visits the store, 3 blocks away from her home at a speed of 1 block per minute.

Thus, she moves 1 block every minute up to 3 minutes.

Thus, we get f(x) = x, 0 < x ≤ 3.

After this, she spends 3 minutes at the store, giving f(x) = 3, 3 < x ≤ 6.

Then she moves towards the bank, in the same direction, 3 blocks away at the speed of 1 block every 2 minutes.

Thus, in every minute, she travels 1/2 block.

Thus, the function can be designed as follows:

f(x) = 3 + (1/2)(x - 6), 6 < x ≤ 12,

or, f(x) = x/2, 6 < x ≤ 12.

Now, we are given that she stops at the bank for 6 minutes.

Thus, we get, f(x) = 6, 12 < x ≤ 18.

Now, she drove back home, at the speed of one block every minute.

Thus, we get f(x) = 6 - (x - 18), 18 < x ≤ 24,

or, f(x) = 24 - x, 18 < x ≤ 24.

At the 24th minute, Eva reaches her house back, giving f(x) = 0, x > 24.

Thus, the complete function can be shown as:

[tex]f(x) = \begin{cases} & 0\text{ if } x= 0\\ & x\text{ if } 0 < x\leq 3 \\ & 3\text{ if } 3 < x\leq 6\\ & x/2\text{ if } 6 < x\leq 12\\ & 6\text{ if } 12 < x\leq 18\\ & 24-x\text{ if } 18 < x\leq 24 \\ & 0\text{ if } x > 24 \end{cases}[/tex]

O Zeema gets paid £1870 per month in equal monthly payments.

The amount paid each month to repay the loan over the course of the loan is known as the monthly payment. When a loan is taken out, not only the principal, or the original amount borrowed, but also the interest that accrues, must be repaid.

Now when the total amount earned in a month is given then the monthly payment is calculated by dividing the total amount by 12 as there are 12 months in a year.

Annual amount earned by O Zeema=£22,440

Therefore monthly amount earned=£22,440 ÷12=£1870

In 12 days a professional gamer got 6561 points

We know that average is ratio of the sum of all observations and the number of total observations.

For given question,

A professional gamer averaged a score of 534 points, every day, for 5 days.

⇒ 534 = (total score of 5 days) / 5

⇒ total score of 5 days = 534 × 5

⇒ total score points of 5 days = 2670 points

Then, for the next 3 days he scored a total of 1827 points.

So, the total points of 8 days would be,

total score points of 5 days +  total score points of 3 days

⇒ 2670 points + 1827 points = 4497 points.

In another 4 days he averaged a score of 516 points each day.

⇒ 516 = (total score of 4 days) / 4

⇒ total score of 4 days = 516 × 4

⇒ total score points of 4 days = 2064 points

So, the total number of points he did in 12 days:

total score points of 5 days +  total score points of 3 days + total score points of 4 days

= 2670 points + 1827 points + 2064 points

= 6561 points

Therefore, in 12 days a professional gamer got 6561 points

Week 3:

Alex makes the most with $234.50

Chris made $272.50 and Michelle makes $206

Step-by-step explanation:

For Chris in week 1, multiply 3/100 x 1500 to get what he makes on commission. That equals $45. $150 + $45 = $195

For Michelle in week 1, multiply 15 x 5 = 75. Also multiply 25 x 6.5 = 162.5 to find how much she gets payed by the Pringles. Add it up to get $237.50

For Alex in week 1, multiply 21 x 8.5 = $178.50

For Chris in week 2, multiply 1/40 x 1000 = $25 to get what he makes on commission for the first $1,000. Then multiply 7/200 x 500 = $17.50 to get when he makes on commission for the sales over $1,000. Add it all up and get $192.50

For Michelle in week 2, multiply 10 x 5 = 50 to find how much she gets payed by the Rogers'. Then multiply 28 x 6.5 = 182 to find how much she gets payed by the Pringles. Add it up to get $232

For Alex in week 2, multiply 25 x 7 = 175 to find out how much he earns for 5 hours each day. Then, since Alex worked another 50 minutes, multiply 5/6 x 7 = 5.83. Add it up to get $180.83

For Chris in week 3, multiply 3/200 x 1500  = 42.50 to get what he makes on commission. Then add it with the base salary of 250 to get $272.50

For Michelle in week 3, since the Pringles paid her double, she earned $13 an hour. So, multiply 13 x 12 = 156. Then add it with the $50 she makes from the Rogers' and get $206

For Alex in week 3, multiply 7 by the number of hours he works each day in the week. Get $234.50

We'll begin by converting 19 Km/L to miles per litres. This can be obtained as follow:

1 Km/L = 0.621371 mile per litre

Therefore,

19 Km/L = (19 Km/L × 0.621371 mile per litre) / 1 Km/L

19 Km/L = 11.806 miles per lire

We can convert 11.806 miles per litre to miles per gallon as follow:

1 mile per litre = 3.78541178 miles per gallon

Therefore,

11.806 miles per litre = (11.806 miles per litre × 3.78541178 miles per gallon) / 1 mile per litre

We are also given the distance between the two points P and Q is:

PQ = 10 units.

We know that

Distance = P ± Q

10 = P ± 13

so, we get that

10 = P + 13 or 10 = P - 13

P = 10 - 13 or P = 13 + 10
