Write the equation of the circle graphed below.

Answers

Answer 1

Answer:

(x + 2)² + (y + 2)² = 0.75²

Step-by-step explanation:

Standard form

(x - h)² + (y - k)² = r²

the center is (h, k) = (-2, -2)

the radius is r = 0.75

(x + 2)² + (y + 2)² = 0.75²

Answer 2

Answer:

(x + 2)^2 + (y + 2)^2 = 0.5625

Step-by-step explanation:

By looking at the graph, we can see the center of the circle is (-2, -2) and by counting the squares, the radius is 0.75.

The standard form of a circle equation is:

(x - h)^2 + (y - k)^2 = r^2

where (h, k) is the center and r is the radius.

We can substitute our values in to get:

(x + 2)^2 + (y + 2)^2 = 0.5625

Okay so, first put a dot on the number three. Next, go down one and over two from that spot (2, 2) and so on.

Step-by-step explanation:

Answer and step-by-step explanation:

Here, we are given a linear equation, meaning that the graph is going to be a straight line. Firstly, we must identify the slope and the y-intercept of the line.

y = -1/2x + 3

The -1/2x is our slope, and the 3 is our y-intercept. So, let's plot the coordinate (0, 3) because that is the y-intercept. Lastly, we must find how steep the line is, and what direction it goes to. As you can see, it is negative, so that means that the slope will go from the top left to the bottom right. And, the slope is -1/2, which means that for every time you go to right two, you will also go down one. Hope this helps!

How many onto functions are there from a set with three elements to a set with eight elements?

Answers

Answer:

0 onto functions

Step-by-step explanation:

Let the sets be [tex]A\ and\ B[/tex] such that:

[tex]n(A) = 3[/tex]

[tex]n(B) = 8[/tex]

Required

The number of onto functions

The condition for onto functions is:

For there to be an onto function from set A to set B, the number of elements of B must be less than the elements in set A

Since n(B) > n(A) i.e. 8 > 3

Then, there can't be onto functions from A to B

Find the length of side x in simplest radical form with a rational denominator.
60°
V3
30°
X

Answers

Answer:

4√3/3

Step-by-step explanation:

Find the diagram attached below

Considering angle 60°

Opposite side = 2

Hypotenuse = x

Using the SOH CAH TOA identity

sin theta = opposite/hypotenuse

sin 60 = 2/x

x = 2/sin60

x = 2/(√3/2)

x = 2 * 2/√3

x = 4/√3

Rationalize

x = 4/√3 * √3/√3

x = 4√3/3

Hence the value of x in its simplest form is x = 4√3/3

m[tex]\angle{LMN[/tex] is 108°.

What is an angle ?

To form an angle we need at least two rays with one common endpoint this is also known as vertex of the angle.

There are many types of angles.For example - Acute angle, Obtuse angle, Right angle, complementary angle, Supplementary angle.

The most common unit for measuring an angle is in degrees and in radians,Where 1 rad = 180°.

According to the given question.

[tex]\angle{LMP[/tex] and [tex]\angle{PMN[/tex] are given they are 85° and 23° respectively.

From the given diagram we can observe that [tex]\angle{LMN[/tex] is sum of the angles [tex]\angle{LMP[/tex] and [tex]\angle{PMN[/tex].

∴ [tex]\angle{LMP[/tex] + [tex]\angle{PMN[/tex] = [tex]\angle{LMN[/tex]

85° + 23° = 108°.

So, [tex]\angle{LMN[/tex] = 108°.

A distribution center makes deliveries to food stores on a weekly basis. On the average, 50 stores are served daily. A typical store places an order for 10,000 lb of various products. 4 store orders can be placed on a delivery truck. Trucks are loaded in 5 hours. The distribution center operates an 8 hour shift. How many truck doors are needed?

Answers

Answer:

3 doors needed

Step-by-step explanation:

The computation of the no of trucks doors that are needed is shown below:

= serve daily ÷ no of store orders ÷ no of store orders

= 50 ÷ 4 ÷ 4

= 3 doors needed

First we divided the serve daily from the no of store orders and then the value that comes so it would be divided by no of store orders again so that the no of truck doors could come

Answers

Answer:

Triangles always have 180°, split in some manner between the three angles. With two of the three angles given, you can set up a relatively simple equation, where the third angle is assigned to the variable x:

45°+85°+x=180°

130°+x=180°

x=50°

Squids, which are carnivores that feed on fish and zooplankton, are another important link in these food webs, as they are in turn eaten by seals and toothed whales (Figure 1).
