It is in order from least to greatest
That is a rule in it I beleive

1.8, 2.85, 3.90, 4.95, 6

To find the rule for this sequence, you find the difference between 2 numbers ..

1.8 + n = 2.85
n = 1.05

2.85 + n = 3.90
n = 1.05

3.90 + n = 4.95
n = 1.05

4.95 + n = 6
n = 1.05

As you can see, each have a difference of +1.05

The rule for this sequence is adding 1.05

Evaluate functions from their graph

suter [353]

Answer:

f(1) = 1

Step-by-step explanation:

To evaluate a function, you see the y value it gives when you plug in the x value.

When you plug in 1 for the x value, the y value is also 1, so f(1) = 1

A rectangle has a perimeter of 103.6 inches and a base of 39 inches. What is the height?

rusak2 [61]

Answer:

12.8 IN.

Step-by-step explanation:

So, what exactly is perimeter?

Perimeter= 2L+ 2W

In this question we were given the length.ie.Base and the perimeter itself.

●Length is 39 In.

●Perimeter is 103.6 In.

●We don't know the width.

But, as per given the question, we know that;

1 length = 39 In.

2 lengths= 78 In.

Now that we know the total length we can find the total width.

See as follows,

103.6 - 78= 25.6

2 widths= 25.6

1 width= 25.6÷2

=12.8 In

Find an equation of the circle that satisfies the given conditions. (Use the variables x and y.)

prohojiy [21]

Answer:

$x^2 + y^2 = 52$

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, $(x_1,y_1)$ and $(x_2,y_2)$ . The distance between them is given by:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Equation of a circle:

The equation of a circle with center $(x_0,y_0)$ and radius r has the following format:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

Center at the origin;

This means that $x_0 = 0, y_0 = 0$

$(x - x_0)^2 + (y - y_0)^2 = r^2$

$(x - 0)^2 + (y - 0)^2 = r^2$

$x^2 + y^2 = r^2$

Passes through (4, 6)

The radius is the distance from this point to the center. So

$r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$r = \sqrt{(4-0)^2+(6-0)^2}$

$r = \sqrt{16+36}$

$r = \sqrt{52}$

$r^2 = 52$

Then

$x^2 + y^2 = r^2$

$x^2 + y^2 = 52$

W varies jointly as x and p . If w=78 when x=2 and p=10, find x when w=858 and p=5.5

Lemur [1.5K]

W=kxp
where
k is the constant of proportionality given by:
k=w/xp
 If w=78 when x=2 and p=10 then
k=78/(2*10)
k=3.9
thus the formula is:
w=3.9xp

b] find x when w=858 and p=5.5
plugging the values in the formula we get:
858=3.9×5.5×x
hence
x=858/(3.9×5.5)
x=358/21.45
x=16.69

A 222-inch pipe is cut into two pieces. One piece is five times the length of the other. Find the length of the shorter piece.

djverab [1.8K]

Answer:

<h3>Notice This is example of another question u can try this like it</h3>

Step-by-step explanation:

Say, length of one piece = x inch

Length of second piece = 3x inch

3x+x= 188

4x= 188

x= 47

One piece = 47 inches

Other piece= 141 inches
