Can someone help me?

Answer:

Center (0, 1)

Radius 1

x-intercept (0, 0)

y-intercept (0, 0), (0, 2)

Step-by-step explanation:

(1) A circle that has center (a, b) and radius r can have the equation as below:

(x - a)^2 + (y - b)^2 = r^2

Re-write the original equation: x^2 + (y - 1)^2 = 1, we have:

(x - 0)^2 + (y - 1)^2 = 1^2

=> The center of this circle: (a, b) = (0, 1) and the radius r = 1

(2) To find out the x-intercept, we substitute y = 0 into original equation.

=> x^2 + (0 - 1)^2 = 1

=> x^2 + 1 = 1

=> x^2 = 0

=> x = 0

=> x-intercept (0, 0)

(3) To find out the y-intercept, we substitute x = 0 into original equation.

=> 0^2 + (y - 1)^2 = 1

=> (y - 1)^2 = 1

=> y - 1 = -1 or y - 1 = 1

=> y = 0 or y = 2

=> y-intercept (0, 0) and (0, 2)

Answer:

Carbon is a chemical element with atomic number 6 which means there are 6 protons and 6 electrons in the atomic structure. The chemical symbol for Carbon is C. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. Carbon is one of the few elements known since antiquity.

The equation of the line of best fit is: y = -2.33x + 591.78

The correlation coefficient is: -0.99

There is a strong negative correlation

Step-by-step explanation:

The negative correlation is seen in the sign of the correlation coefficient, which is negative.

The correlation is strong because the absolute value of the correlation coefficient (0.99) is near to one

Answer B

One thing that gave it away was that we are dealing with a 30-60-90 triangle so in the final equation we should have (x=Any number) [tex]x\sqrt{3}[/tex] not square root two

The triangle ABC with ∠C as right angle , BC = 7 and ∠b = 30 degrees has AC as 7√3 / 3

A right angle triangle is a triangle that has one of its angle as 90 degrees. Therefore, the sides can be found using trigonometric ratios.

BC = 7 units

∠b = 30°

Hence, AC can be found as follows;

tan 30° = opposite / adjacent

tan 30 = AC / 7

cross multiply

AC = 7 tan 30

AC = 7 × 1 / √3

AC = 7 / √3

AC = 7√3 / 3

Answer:

20 minutes

Step-by-step explanation:

The mean, or average of a data set can be found by adding all the values together, and dividing by the number of values.

The data set is: 20 minutes, 22 minutes and 18 minutes

1. Add the values together

Add all the numbers in the set together.

Data set: 20, 22, 18

Add them: 20+22+18

60

2. Divide by the number of values

Count how many numbers are in the set.

In this set, there are 3 numbers.

Divide 60 by 3

60/3 =20

20 minutes

His mean time is 20 minutes.

Answer:

30 minutes

Step-by-step explanation:

Mean means the average so the average equals (20+22+18)/2

= 30

Answer:

x = 9

Step-by-step explanation:

We know sum of interior angles of a polygon = [tex](n-2)\times 180[/tex]

For a triangle (having n = 3),

Sum of interior angles = (3 - 2)×180°

                                     = 180°

In ΔVWX,

m∠V = (12x + 19)°

m∠W = (2x + 19)°

m∠X = (x + 7)°

And m∠V + m∠W + m∠X = 180°

(12x + 19)° + (2x + 19)° + (x + 7)° = 180°

(12x + 2x + x) + (19 + 19 + 7) = 180°

15x + 45° = 180°

15x = 180° - 45°

x = [tex]\frac{135}{15}[/tex]

x = 9

Therefore, value of x = 9.

Answer:

Both Distance formula and Slope formula are used to classify quadrilaterals and triangles, as Distance formula is used to calculate the length of each side while Slope formula is used to find the angle of a line with respect to an axis or another line.

We can classify the figure as finding the lengths of each side by using Distance formula. For example, if we find that a quadrilateral has all 4 sides equal, is it a square. If it has opposite sides equal, it can be a rectangle or a parallelogram, and so on. It can also tell whether a triangle is right angled, isosceles or equilateral.

Slope are used to find angles of the lines. If 2 lines have the same slope, it means they are parallel to each other. If the product of their slopes is -1, it means they are perpendicular to each other

Answer:

The sum of the two leg measures equals the hypotenuse.

Step-by-step explanation:

The answer choice "The measure of the hypotenuse squared is equal to the sum of the side measures squared" is true because it is the Pythagorean Theorem.

The other two answer choices basically describe what a hypotenuse is.

Answer:

The sum of the two leg measures equals the hypotenuse.

Answer:

No. of hours already volunteered + total volunteer hours dedicated in w weeks > = Least volunteer hours required to graduate

=> 52 + 3w >= 90

Step-by-step explanation:

Given that Antonina needs to have worked at least 90 volunteer hours to graduate means that she needs to volunteer either for 90 hours or more than that . Mathematically this can be written as

Total volunteer hours required to graduate greater than or equal to 90

Total volunteer hours required to graduate>= 90

No. of hours already volunteered = 52

no. of hours left for volunteering = Total volunteer hours required to graduate - No. of hours already volunteered = 90 - 52 = 38

No. of hours in one week she can dedicate for volunteering= 3

if w is the number of weeks that Antonina needs to tutor in order to complete her volunteer hours

then total volunteer hours dedicated in w weeks will be = w*No. of hours in one week she can dedicate for volunteering = w*3 = 3w

Thus,

No. of hours already volunteered + total volunteer hours dedicated in w weeks > = Least volunteer hours required to graduate

=> 52 + 3w >= 90

Answer:

The angle of the shaded region is 124.9°

Step-by-step explanation:

Since there's an region inside the circle that is shaded and has an area of 34 pi square units, we can apply the circle's sector area's formula in order to find the angle of this region. The formula is given by:

[tex]\text{sector area} = \frac{\text{angle}*\pi*r^2}{360}\\[/tex]

Applying the data from the problem gives us:

[tex]34*\pi = \frac{angle*\pi*(7*\sqrt{2})^2}{360}\\34 = \frac{angle*(49*2)}{360}\\98*angle = 34*360\\angle = \frac{12240}{98} = 124.9\°[/tex]

The angle of the shaded region is 124.9°

Answer:

15x + 10.

Step-by-step explanation:

To find the area of a rectangle, recall the formula is A = l × w. Therefore:

A = (3x + 2) (5)

Distribute the '5':

A = 15x + 10

Therefore, the area of the rectangle of 15x + 10.

Answer:

15x+10 units ^2

Step-by-step explanation:

The area of a rectangle can be found using:

A = l * w

The length of the rectangle is 3x+2 and the width is 5.

l=3x+2

w=5

Substitute these values into the formula.

A= 3x+2 *5

This can be rewritten as: (Commutative property of Multiplication)

A= 5* 3x+2

A= 5(3x+2)

Distribute the 5. Multiply each term inside the parentheses by the number outside the parentheses.

A= (5*3x) + (5*2)

A= 15x +10

A= 15x+10 units^2

The area of the rectangle is 15x+10 square units.
