The equation representing the circle A is (x – 4)² + (y + 5)² = 36.

What is circle?

A circle is a spherical shape without boundaries or edges. A circle is a closed, curved object with two dimensions in geometry.

The general equation of circle is given by equation

( x - h )² + ( y - k )² = r²

Where,  ( h, k ) is the centre and 'r' is the radius.

As, the circle has a shift of 4 units on the +x axis.

The circle has a shift of the 5 units on the -y axis.

As, the circle has a radius of 6 units from the graph.

So, (h,k) = (4, -5).

Substitute the values of (h,k) in the general equation of the circle.

( x - 4 )² + ( y - (-5) )² = 6²

( x - 4 )² + ( y + 5 )² = 36

Therefore, the equation of circle becomes ( x - 4 )² + ( y + 5 )² = 36.

First, you need to graph a triangle using the points given.

Then reflect across y = x

R is (3,0) which when reflected across y = x is (0,3)

S is (3,3) which when reflected across y = x is (3,3)

R is (4,0) which when reflected across y = x is (0,4)

The Beechcraft 1900D is a commuter airplane with a fuel capacity of 665 gallons. The function that represents how the amount of fuel changes as a function of distance flown is f(x)=−0.9x+665, where x represents miles flown, and f(x) represents the amount of fuel remaining. What is the rate of change for this scenario?

Answers

Given:

The  function that represents how the amount of fuel changes as a function of distance flown is

[tex]f(x)=-0.9x+665[/tex]

where x represents miles flown, and f(x) represents the amount of fuel remaining.

To find:

The rate of change for this scenario.

Solution:

The slope intercept form of a linear function is

[tex]y=mx+b[/tex]        ...(i)

Where, m is the slope or rate of change and b is the y-intercept.

We have,

[tex]f(x)=-0.9x+665[/tex]        ...(ii)

On comparing (i) and (ii), we get

[tex]m=-0.9[/tex]

Therefore, the rate of change for this scenario is -0.9. It means, the amount of fuel in the airplane is decreasing by 0.9 gallons per mile.

Answers

Answer:

x = 20°

Step-by-step explanation:

3x - 10° + 5x + 30° = 180° { being co-interior angles }

8x = 180° - 20°

8x = 160°

x = 160° / 8

How long does it need to keep $600 in an account that pays 2.75% annual simple interest to earn $264?

Answers

Answer:

16 years

Step-by-step explanation:

Principal amount (P) = $600

Rate of interest (R) = 2.75%

Simple interest (S.I.) = $264

Let t denotes time period.

[tex]S.I.=\frac{PRT}{100}[/tex]

[tex]264=\frac{600(2.75)t}{100} \\\\t=\frac{264(100)}{600(2.75)}[/tex]

[tex]t=16[/tex] years.  

Therefore,

interest of $264 will be earned in 16 years.

What is the missing value of 5x-2y=30 (8,)

Answers

Answer:

In this equation, we can start by understanding that "x" has a value of 8, as given in the ordered pair. When multiplied by 5, this leads to "40 - 2y = 30". Next, we can subtract 40 from both sides of the equation. This leads us to a value of "-2y = -10". The next step would be to divide both sides by -2 as a way of isolating "y", which leads us to a final value of "y = 5". The final ordered pair would be (8,5).

Answers

Answer:

314,880

Step-by-step explanation:

If the population decreases by 1.6% per year, this means the population is 98.4% of the population of the previous year. What this means is we can multiply the current population, 320,000, by 98.4/100, as 98.4/100 is equivalent to 98.4%. This gets us 314,880.

Carter and his children went into a bakery where they sell cupcakes for $3 each and
cookies for $0.50 each. Carter has $35 to spend and must buy a minimum of 15
cupcakes and cookies altogether. If x represents the number of cupcakes purchased
and y represents the number of cookies purchased, write and solve a system of
inequalities graphically and determine one possible solution. (I need 2 inequality’s)

Answers

Answer:
3x + 0.5y = 35
x + y >/= 15

Possible solution: (11, 4)
11 cupcakes, 4 cookies
____________
Cupcakes = x
Cookies = y

Cupcakes are $3 each —> 3x
Cookies are $0.50 each —> 0.5y

$35 to spend: less than or equal to =
3x + 0.5y = 35

Minimum of 15: greater than or equal to >/= 15

x + y >/= 15
____________

3x + 0.5y = 35
x + y >/= 15

Solve second for y:
y >/= 15 - x

Substitute into first:
3x + 0.5(15 - x) = 35
3x + 7.5 - 0.5x = 35

Combine like terms
2.5x + 7.5 = 35

Subtract 7.5
2.5x = 27.5

Divide by 2.5
x is less than or equal to 11

So y is less than or equal to 4

Check:
4 + 11 = 15 :)

3*11 + 0.5*4 = 35
33 + 2 = 35
35 = 35 :)
