Answer:
see explanation
Step-by-step explanation:
x = r cosΘ
y = r sinΘ
with r = 54 and Θ = 69°, thus
x = 54cos69° ≈ 19.4
y = 54sin69° ≈ 50.4
Thus (54, 69° ) as an ordered pair
= ![\left[\begin{array}{ccc}19.4\\50.4\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D19.4%5C%5C50.4%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Hello :
4√2-7√2= (4-7)√2 = -3√2
Answer:
x=-7
Step-by-step explanation:
divide 12 on both sides and that equals -7
Answer:
A) TA
Step-by-step explanation:
A radius goes from the center of a circle to the outside edge.
RP connects two points on the outside edge of the circle without going through the center. This is not a radius.
TR connects two opposite points on the outside edge of the circle while going through the center. This is a diameter, not a radius.
GP connects two opposite points on the outside edge of the circle while going through the center. This is a diameter, not a radius.
TA connects the center of the circle to the outside edge. This is a radius.
