Answer:

SW

Step-by-step explanation:

Answer:

A. True

Step-by-step explanation:

Given:

O is the center of the Circle

Chord BC is the line segment passing from the center of circle

Chord: It is a line segment whose end points lies on the circle.

Diameter: It is defined as a line segment passing from the center of the circle whose end point lies on the circle.

Hence chord BC is a diameter of the circle as passes from the center O of the circle and its end points B,C lies on the circle.

Hence the statement is TRUE

Yes, The chord BC is a diameter of circle C.

Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.

We have to given that;

To check The chord BC is a diameter of circle C.

Now, WE know that;

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Here, The line segment BC is passing through the center O.

Hence, The chord BC is a diameter of circle C.

A fraction, like 2/9, has a numerator and a denominator separated by a dividing line.

2 is the numerator, because it is the number above the dividing line.

9 is the denominator because it is the bottom number of the dividing line.

To convert 2/9 to a decimal, divide the numerator by the denominator.

How much does the Kyrie 5 cost?

Step-by-step explanation:

Correct option is A)

Let Q(h,k) be the image of P(3,3) w.r.t the line mirror x+y=0

k−3

=

−2(6)

⇒h−3=k−3=−6

⇒h=−3,k=−3

So, the image is Q(−3,−3).

In the second transformation, point Q is translated horizontally 3 units to the left and vertically 3 units up.

So, the coordinates of new image is (−3−3,−3+3) i.e. (−6,0)

In the third transformation, point (−6,0) is reflected w.r.t the line y=x

So, the final image is (0,−6).

Was this answer helpful?

In h(x) = 4x^2 + 3x - 2, there is an x contained with h as well as an x in the expression. To find h(j + 1), we'll need to plug in (j + 1) everywhere that there is an x.

h(j + 1) = 4(j + 1)^2 + 3(j + 1) - 2

h(j + 1) = 4(j^2 + 2j + 1) + 3j + 3 - 2

h(j + 1) = 4j^2 + 8j + 4 + 3j + 3 - 2

h(j + 1) = 4j^2 + 11j + 5

Answer:

4536.459792... ft^2 or 1444pi ft^2

Step-by-step explanation:

Surface area of a sphere

A = 4 x pi x r^2

Since we have the diameter we can divide that by two to get the radius

38/2 = 19

Then we plug the digits we have into the equation

A = 4 x pi x 19^2

A = 4536.459792... or 1444pi

Answer:

Step-by-step explanation:

Hi there!

We are given the equation of a line, and we want to write the equation of this line in slope-intercept form

Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y-intercept

First, we need to find the slope of the line

The slope (m) can be calculated from 2 points, using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

First, let's find 2 points on the line:

The intercepts - the points where the line hits the x and y axis are a good place to start; the intercepts of this line are (4,0) and (0, 4), which will also work for calculating the slope

Let's label the values of these 2 points to avoid any confusion and mistakes when calculating.

[tex]x_1=4\\y_1=0\\x_2=0\\y_2=4[/tex]

Substitute into the formula

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{4-0}{0-4}[/tex]

Subtract

m=[tex]\frac{4}{-4}[/tex]

Divide

m = -1

The slope of the line is -1

We can substitute that into our equation:

y = -x + b (when -1 is the leading coefficient, only adding a minus sign in front of the variable will suffice)

Now we need to find b

As said earlier, b is the value of y at the y intercept

The point of the y intercept is (0, 4), and the value of y at this point is 4

So substitute 4 as b into the equation

y = -x + 4

Answer:

A.  The probability of event B​ occurring, given that event A has occurred

Step-by-step explanation:

Conditional probability

A probability is conditional if is depends on what has already happened.

The probability that event B happens, given that event A has already happened is "B given A" or P(B | A)

Therefore, P(B | A) means "The probability of event B​ occurring, given that event A has occurred"

Additional information:

P(A | B) means "A given B", i.e. the probability of event A​ occurring, given that event B has occurred

P(A ∩ B) means the probability of event A and event B both happening.
