Answer:

x² + (y + 8)² = 81

Step-by-step explanation:

Centre (h,k) = (0,-8)

radius (r) = 9

(x - h)² + (y - k)² = r²

(x - 0)² + (y + 8)² = 9²

x² + (y + 8)² = 81

Answer:

f(1) = 4

Step-by-step explanation:

f(1)  means let x=1 and find the y value at that point on the graph

At x=1 there is an open circle and a closed circle.  The open circle means that the function does not have a value at that point, so we use the closed circle

f(1) = 4

Answer:

[tex]t=\dfrac{d}{s}[/tex]

Step-by-step explanation:

Dan is driving with an average speed of s. He is driving a total distance of d.

The average speed of an object is given by :

Average speed = total distance/total time

Let b the time of his trip

So,

[tex]s=\dfrac{d}{t}\\\\or\\\\t=\dfrac{d}{s}[/tex]

So, the formula for the total time of his trip is [tex]\dfrac{d}{s}[/tex].

Answer:

Answer: 2/7

Step-by-step explanation:

There are 7 letters in January, and 2 "a"s in order to find the probability, simply take 2/7. You can either leave it in the fraction form, or use the calculator, showing you have a 0.2857% chance of picking an "a"

2/7

there are 7 letters in jAnuAry and as you can see there are 2 A's so there is a 2/7 chance which is higher of a chance than the rest of the letters which are 1/7 each so it is most likely you would draw A although I can't fully say that because there is a 5/7 chance of drawing the other letters. Another way to say it is there is a 0.28571428571% chance of drawing A but there is a 0.71428571428% chance of drawing any other letter.

Answer:

We have the value as;

8x/5

Step-by-step explanation:

Here, we want to get the breakdown of the given expression

We have (x^2 - 9) as (x-3)(x + 3)

So we have;

2x/(x + 3) * (x-3)(x+3)/5 * 4/(x-3)

= 2x * 4/5= 8x/5

Answers:

==========================================================

Explanation:

Match up (7x+3)(7x-3) with (a+b)(a-b)

We have

We can see that a = 7x and b = 3

Furthermore, we can say,

(a+b)(a-b) = a^2 - b^2

(7x+3)(7x-3) = (7x)^2 - (3)^2

(7x+3)(7x-3) = 49x^2 - 9

The values of a and b are 7x and 3 respectively

(7x+3) (7x−3)

Using the format

(a + b)(a − b) = a² − b²

Therefore,

a = 7x

b = 3

Therefore,

From (a + b)(a − b) = a² − b²

(7x+3) (7x−3) = (7x)² - 3²

(7x+3) (7x−3) = 49x² - 9

Answer: 6 meters

Step-by-step explanation: 6 is also what we call a cube root of a number. A cube root is a number you multiply by itself 3 times to get the product.

6 times 6 equals 36. 36 times 6 equals 216.

(6 times 6 times 6 = 216)

Answer:

y = 2x + 8

Step-by-step explanation:

To find the line, use the equation y = mx + b.

Plug in the slope and given point, then solve for b:

y = mx + b

2 = 2(-3) + b

2 = -6 + b

8 = b

Plug in the slope and b into the equation:

y = 2x + 8

So, the equation of the line is y = 2x + 8

Answer:

162 ft^3

Step-by-step explanation:

volume = area of base * height

V = 22 1/2 ft^2 * 7 1/5 ft

Change the mixed numerals into fractions.

V = 45/2 ft^2 * 36/5 ft

Multiply the fractions.

V = 45/2 * 36/5 ft^3

Switch the denominators.

V = 45/5 * 36/2 ft^3

Simplify each fraction.

V = 9 * 18 ft^3

V = 162 ft^3
