On a coordinate plane, point A is at (3, 3) and point B is at (negative 3, 3). Point B is the image of point A when A is rotated
90° counterclockwise around the origin. Point B must be the same from the origin as point A.
1 answer:
Answer:
Point B must be at the same distance from the the origin as point A.
Step-by-step explanation:
Coordinates of point A = (3, 3)
When point A is rotated 90° counterclockwise around the origin, coordinates of the new point B will be (-3, 3)
Distance from origin to point A =
Similarly, distance of point B from the origin =
Therefore, distances of both the points from the origin are same.
Point B must be at the same distance from the the origin as point A.

Answer:
$1.25.
Step-by-step explanation:
We have been given that at a football game Jasmine bought a soft pretzel for $2.25 in a bottle of water for $1.50 she paid with a $5 bill.
First of all let us find how much Jasmine spent on soft pretzel and water bottle by adding the cost of both items.
To find the amount that Jasmine will get as a change we will subtract the amount spent on both items from 5.
Therefore, Jasmine will get $1.25 back as change.
Answer:
C
Step-by-step explanation:
Use the sine ratio in the left, right triangle to find the common side to both triangles and the exact values
sin60° = , cos45° =
, thus
sin60° = =
=
( cross- multiply )
2 × opp = 21 ( divide both sides by 2 )
opp =
Now consider the right triangle on the right, using the cosine ratio
cos45° = =
=
( cross- multiply )
x = ×
=
→ C
