Find the area of a regular octagon with side length 6 cm

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:

5.56 m

Step-by-step explanation:

Circumference = 2πr

r is the radius, however the diameter is given. The radius is half the diameter. So the radius is:

1.8 ÷ 2 = 0.9

Circumference = 2 × π × 0.9

= 5.56 m ( in 3 significant figures )

Answer:

3x +7x -2y + 3y

10x - 5y

5xy

Answer and Step-by-step explanation:

The answer is A.

y = x + 2 and y = -2x + 4

This is because:

- The graph going from left to right matches the first equation, in which the graph has a slope of 1 and has a y-intercept at (0, 2).

- The graph going from right to left matches the second equation, in which the graph has a slope of -2 (Since it is going from right to left), and has a y-intercept at (0, 4).

Answer:

[tex](-6, 0)[/tex]

[tex](0, -2.3)[/tex]

[tex](0,\frac{3}{4})[/tex]

Step-by-step explanation:

Solving (1). x-intercept: -6

At x intercept, [tex]y= 0[/tex]

So, the ordered pair is: [tex](-6, 0)[/tex]

Solving (2):  y-intercept: -2.3

At y intercept, [tex]x = 0[/tex]

So, the ordered pair is: [tex](0, -2.3)[/tex]

Solving (3): y-intercept: 3/4

At y intercept, [tex]x = 0[/tex]

So, the ordered pair is: [tex](0,\frac{3}{4})[/tex]

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

Answer:

.53

Step-by-step explanation:

your diameter is .82,so divide it by two to get your radius

Answer:

25

Step-by-step explanation:

For these types of problems you'll need the Pythagorean theorem (woohoo..). This amazing formula looks like: a^2 + b^2 = c^2. The a and b in this formula are the legs of the triangle, the straight non-diagonal lines. The c stands for the hypotenuse which is the diagonal line.

Since you have both of the legs we can go ahead and plug that into our equation: 15^2 + 20^2 = c^2.

NOTE: It doesn't matter which leg you plug into which variable! Just make sure it's not c!

With exponents, it just means to multiply the number by itself. 15^2 is the same as 15(15). So, simplifying the equation, we get: 225 + 400 = c^2.

This part is pretty straightforward. I mean, unless you don't remember addition... Adding it together, you will get 625 = c^2.

This part kinda requires a calculator if you don't know all of your square roots. Luckily, this is a perfect root and goes into 25.

And that, my friend, is your answer. Hope this helped :)

Answer:

x=5

Step-by-step explanation:

First off, you need to subtract 67 from 17 to get the variable alone.

That will leave you with -10x=-50

Then you need to divide -10 and -50,

Two negatives make a positive so

x=5

Answer is C

Answer:

The y values are decreasing, I would say it's decay.

Answer:

y - 2x = 3

Step-by-step explanation:

Use the point-slope formula y - k = m(x - h), with h = 0, k = 3 and m = 2:

y - 3 = 2(x - 0), or

y - 3 = 2x, or

y - 2x = 3

Note that the given point, (0, 3), is the y-intercept of this line, and so we immediately know b in y = mx + b:  it is 3.

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

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
