Answer:

Yes

Step-by-step explanation:

It lies on the circle because the radius is 2 and the point goes down two units just like the radius

Answer:

yes

Step-by-step explanation:

the radius extends out 2 points throughout the entire circle therefore -2 will be reached as it is 2 units below the center of (4, 0)

it's 452.16 because it's the closest estimate

Answer:

A: Three-fifths

Step-by-step explanation:

I have attached an image to depict this question.

We can see that the point at which the radius goes on the unit circle is a coordinate (x, y)

We are told this coordinate is (0.6, 0.8)

Now, in these type of unit circle diagrams;

x = cos θ and y = sin θ.

Thus;

cos θ = 0.6

cos θ = 6/10

Simplifying gives;

cos θ = 3/5

Answer:

A. 3/5

Answer:

4

Step-by-step explanation:

first you put the numbers in order from least to greatest

1,1,1,1,2,2,2,4,12,13,15,15,15,16,16

next find the middle number(s)

1,1,1,1,2,2,2,4,12,13,15,15,15,16,16

the middle number is your median

*if you have 2 middle numbers just add the then divide it by 2 to find the median

Answer:

y=4x + 10

Step-by-step explanation:

Parallel lines always have the same slope. The point that you have is the y-intercept because the x is 0. So now you have both the slope and y- intercept and just need to sub it into the y=mx+b equation

The equation of line passes through the point (0, 10) will be;

⇒ y = 4x + 10

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (0, 10).

And, The parallel line is,

⇒ y = 4x - 3

Now,

Since, The equation of line passes through the point (0, 10).

So, We need to find the slope of the line.

Since, The slope of the parallel line is same.

Hence, Slope of the line is,

y = 4x - 3

m = dy/dx = 4

m = 4

Thus, The equation of line with slope 4 is,

⇒ y - 10 = 4 (x - 0)

⇒ y - 10 = 4x

⇒ y = 4x + 10

Therefore, The equation of line passes through the point (0, 10) will be;

⇒ y = 4x + 10

Step-by-step explanation:

Answer:

No, these segments do not form a right triangle.

Step-by-step explanation:

We need to calculate the distances between the points, taking 2 at a time:

From (-1, 6) to (4, 2), x increases by 5 and y decreases by 4.  The distance between the two points, by the Pythagorean Theorem, is d = √(5² + 4²), or √41.

From (-1, 6) to (7, 6) x increases by 8 but y stays the same:  6.  The distance between these two points is therefore 8.

Finally, from (4, 2) to (7, 6), x increases by 3 and y by 4, and so d = 5.

So now we have the 3 side lengths:  √41, 8 and 5.

Squaring them, we get 41, 64 and 25.  These do not satisfy the Pythagorean Theorem:  41 + 25 is not equal to 64.

No, these segments do not form a right triangle.

Yes

Step-by-step explanation:

Both sides are equal and the angles are too

Answer:

answer is (no) it is congruent

Step-by-step explanation:

I=P*R*T/100

R= I*100/P*T

so rate= I*100/3000*0.5

= 30000/1500

= 300/15

=20%

pls gimme brainliest I need it

Answer:

R = 20%

Step-by-step explanation:

Given

I = PRT , substitute corresponding values

300 = 3000 R × 0.5

300 = 1500 R ( divide both sides by 1500 )

0.2 = R ( multiply value by 100% ) , that is

R = 0.2 × 100% = 20%

Answer: x =67

Step-by-step explanation:

The equation to solve this is (x - 22) + 135 = 180

1) To solve for x, you must remove the parenthesis

x - 22 + 135 = 180

2) Simplify the equation...

x - 113 = 180

3) Simplify the equation

180-113 = x

3) Subtract to solve

180 - 113 = x

x = 67

Answer :

As shown in the figure the angles x - 22 and 135 lie on a straight line . So we may solve it using linear pair property that states that the sum of angles lying on a straight line is 180° .

Thus the correct answer is option d that is x = 67
