Answer:
Marry's seat is units far from Betty's seat
Step-by-step explanation:
We are given that Class of Math is mapped on a coordinate grid and center point of the hall is at origin.
Coordinates of Mary's seat are (2,2) and Coordinates of Betty's seat are (6,7). We have to find how far is Mary's seat to Betty's seat. In order words, we have to find the distance between Marry's seat and Betty's seat.
Remember that whenever the coordinates of two points are given, the distance between them is calculated using the distance formula. The distance between two points and is given by distance formula as:
Here, the points with subscript 1 are initial points (2,2) and the point with subscript 2 are final points (6,7). Using these values in the formula, we get:
This means, Marry's seats is units far from Betty's seat
Answer:
4y^3/2
Step-by-step explanation:
The 4 will remain 4 so we'll leave that alone. √y³ can be written as y^3/2. The way I like to remember how to write fractional exponents is that the index of the radical is the denominator of the fractional exponent and the exponent inside the radical is the numerator.
Answer:
Step-by-step explanation:
The vertex of an inscribed angle can be anywhere on the circle as long as its sides intersect the circle to form an intercepted arc. The Inscribed Angle Theorem states that the measure of an inscribed angle is half the measure of its intercepted arc. Inscribed angles that intercept the same arc are congruent.
In a circle, two inscribed angles with the same intercepted arc are congruent. Proof: The measure of each inscribed angle is exactly half the measure of its intercepted arc. Since they have the same intercepted arc, they have the same measure.
